Abstract
This chapter summarizes existing research on mental health among young people in West and Central Africa (WCA). Although data in this area are limited, small scale, nonrepresentative studies suggest that mental disorders are prevalent in WCA due to civil conflicts and political instability, sexual violence, poverty, underemployment and unemployment, substance abuse, and human immunodeficiency virus (HIV)/AIDS among other factors. Mental health conditions put young people in the subregion at risk for poor schooling, health, and livelihood outcomes, exposing them to stigma, isolation, discrimination, and human rights abuses. These findings highlight the need to scale up effective interventions that ensure appropriate and timely access to mental health and minimize the long-term impacts of untreated mental health disorders. Findings also underscore the need for more data on prevalence, risk, and protective factors.

Introduction
Mental disorders are a leading cause of disability in young people globally (Charlson et al., 2014; Mokdad et al., 2016). As many as 20% of the world’s young people (aged between 10 and 24 years) suffer a neuropsychiatric condition (Belfer, 2008), including common disorders like depression and anxiety, or severe forms like psychosis, schizophrenia, and bipolar disorder, as well as alcohol and substance dependence (Remschmidt & Belfer, 2005). Individuals suffering from these disorders have higher mortality risks than the general population (Chesney, Goodwin, & Fazel, 2014). While the onset of most mental disorders occurs during youth (age 12 to 24 years), few disorders are diagnosed or treated in this period (Remschmidt & Belfer, 2005). These conditions often persist for a long time, severely disrupting young people’s access to livelihoods, health care, and education, and exposing them to stigma, isolation, discrimination, and human rights abuses (Sartorius, 2007; Tarter, 2002; Tims et al., 2002). While mental disorders are commonly known for their impact on health and well-being, they are also associated with severe economic losses due to high cost of treatment and impaired ability to work, especially among young people (Esan, Kola, & Gureje, 2012). Inadequate documentation and characterization of young people’s mental health problems hampers planning and appropriate provision of services in most low- and middle-income countries (LMICs) (Jacob et al., 2007).
West and Central Africa (WCA) is one of the youngest subregions of the world (Izugbara et al., 2017). Young people make up more than one-third of the population of the subregion. WCA is also the only subregion of the world where the population of young people is projected to continue growing over the next decade (Ngom, 2017). Key risk factors for mental illness—such as civil conflicts and political instability, poverty, underemployment and unemployment, substance abuse, and human immunodeficiency virus (HIV)/AIDS—are prevalent in the subregion (Betancourt, McBain, Newnham, & Brennan, 2013; Pacione, Measham, & Rousseau, 2013; Sharma, Fine, Brennan, & Betancourt, 2017; United Nations International Children’s Emergency Fund [UNICEF] and Overseas Development Institute [ODI], 2009). Nevertheless, data on young people’s mental and substance use disorders in WCA are limited. A few studies conducted using small, nonrepresentative samples suggest a high burden of child and adolescent mental, neurological, and substance use disorders across several countries in the subregion (Abiodun, 1992; Asare & Danquah, 2016; Cortina, Sodha, Fazel, & Ramchandani, 2012; Ngasa et al., 2017; Nwagu, 2016; Tunde-Ayinmode, Adegunloye, Ayinmode, & Abiodun, 2012; World Health Organization [WHO], 2011; Yoder, Tol, Reis, & de Jong, 2016). Compared to Africa’s other subregions, WCA is projected to experience some of the largest increases in burden of mental and substance use disorders (i.e., Central Africa [196%] and West Africa [129%] compared to Southern Africa [28%] and East Africa [139%]) by 2050 (Charlson, Diminic, Lund, Degenhardt, & Whiteford, 2014), with a significant proportion occurring among young individuals (Cortina et al., 2012). There are, therefore, increasing calls for WCA governments to prioritize the provision of accessible and quality mental health services to their citizens (Abdulmalik et al., 2014; Daar et al., 2014; Kleintjes, Lund, & Flisher, 2010; Semrau et al., 2015).
Arguably, the majority of WCA countries share similar mental health profiles (Abdulmalik et al., 2014). Most of these countries have low policy priority for mental health, with acute funding gaps and inadequate human resources for mental health, widespread misconception about mental health issues, stigmatization, and human rights abuses (Gureje, Lasebikan, Ephraim-Oluwanuga, Olley, & Kola, 2005; Oshodi et al., 2014; Read, Adiibokah, & Nyame, 2009; Saraceno et al., 2007). Therefore, a large “treatment gap” for mental illness exists—over 90% of people with mental illness in LMICs, including in the WCA, are untreated compared to between 44% and 70% in high-income countries (HICs) (Wang et al., 2007). For instance, a review of community-based psychiatric epidemiology studies showed that only 5.9% of young adult Jews in Israel with schizophrenia remained untreated, while the rate in New Zealand in a population of 21-year-olds was 61.5% (Kohn, Saxena, Levav, & Saraceno, 2004). Ironically, this huge gap exists despite considerable evidence that, even within resource-limited countries, cost-effective strategies, such as medications and psychosocial interventions, are available and effective for most mental illnesses (Barry, Clarke, Jenkins, & Patel, 2013; Gureje, Chisholm, Kola, Lasebikan, & Saxena, 2007).
Whereas in HICs there is increasing recognition of mental health problems in young people and their associated impairments and comorbidities, in WCA, the mental health concerns of young people remain neglected, misunderstood, and under-researched (Atilola, Ayinde, Emedoh, & Oladimeji, 2014; Kleintjes et al., 2010). Consequently, there is limited understanding of the burden, drivers, and impact of adolescent mental health in the WCA subregion and of the gaps in research and program implementation. This chapter summarizes existing knowledge on mental health among young people in the subregion. It highlights the burden, drivers, and impact of poor mental health among the subregion’s young people. We also discuss available interventions aimed at improving mental health among these young people and draw attention to gaps in knowledge and programming as well as challenges that get in the way of promoting mental health in WCA. Findings of this study can inform policy-making as well as the design and delivery of programs related to young people’s mental health and well-being.
This chapter draws on insights from relevant peer-reviewed and gray literature on mental and substance abuse disorders among young people in WCA. Mental disorders were defined according to the Diagnostic and Statistical Manual of Mental Disorders (DSM) (American Psychiatric Association [APA], 2000) and the International Classification of Diseases (ICD) (World Health Organization, 1992). We utilized the World Health Organization Assessment Instrument for Mental Health Systems (WHO-AIMS) (only available for Benin, Ghana, and Nigeria) as well as reports from the Ministries of Health to describe the mental health systems available for young people. WHO-AIMS reports on the status of mental health systems in LMICs based on six domains: policy and legislative framework, mental health services, mental health in primary care, human resources, public information and links with other sectors, and monitoring and research. This chapter focuses on the mental health services domain only.
Burden of Mental and Substance Use Disorders in Young People of WCA
Sources of Data for Mental Disorders Among Young People in WCA
There is very limited coverage of representative prevalence data on mental disorders in children and adolescents in WCA. Coverage refers to the proportion of the target population (aged 10 to 24 years) represented by the available data. Virtually no country in sub-Saharan Africa (SSA), including the WCA subregion, has more than 2% coverage for any disorder (Erskine et al., 2017). So far, only Nigeria has conducted a WHO survey of Mental Health and Well-Being to assess the lifetime and 12-month prevalence of mental disorders (Gureje, Lasebikan, Kola, & Makanjuola, 2018). In the absence of large-scale epidemiological surveys on mental disorders, most prevalence data are a product of cross-sectional community-based or clinic-based surveys, which have quality challenges arising from the use of different mental health assessment tools (e.g., screening questionnaires and clinical diagnostic instruments). Other key sources of reliable data include the WHO 2015 country estimates for prevalence and burden of depression and anxiety disorders (not reported by age groups), and a systematic review of the Global Burden of Disease (GBD) Study 2013 (Ferrari et al., 2013) and 2016 (Charlson, Baxter, et al., 2014).
Burden of Mental Disorders Among Young People in WCA
Some of the most common child and adolescent psychiatric disorders worldwide include anxiety disorders, depressive disorders, conduct disorders and delinquency, learning disabilities, and mental retardation (Cortina et al., 2012). In the context of WCA, a systematic review by Cortina et al. (2012) found that between 12% and 30% of children and young people aged 5 to 24 years had mental health problems. Community-based epidemiological studies in various WCA countries have estimated varied degrees of prevalence for different types of mental disorders as shown in Table 11.1. In addition, variations exist across gender. For instance, anxiety and mood disorders are known to affect boys and girls more or less equally, but adolescent girls are much more vulnerable to depression than boys (Bradley, 2001).
Mental disorders are also known to be highly disabling. In the WCA subregion, depressive disorders are among the largest contributors to years lived with disability (YLDs) for both sexes of young people aged 15 to 24 years, even though these disorders affect females more than males in all age groups (Mokdad et al., 2016), and vary by region and country (Institute for Health Metrics and Evaluation, 2017). Among young people, early onset of depressive and anxiety disorders predicts other indirect consequences such as low educational attainment, and consequently lower income, poverty, and noncommunicable diseases (NCDs), such as cardiovascular diseases. A study in Nigeria, for example, showed that child psychiatric disorders are associated with various impairments, reduced functionality, physical illness, premature mortality, and increased inequality in access to economic opportunity (Tunde-Ayinmode et al., 2012).
Poor mental health increases health expenditures and rates of health care utilization, (Charlson, Diminic, et al., 2014), which may in turn act as a barrier to mental health service uptake, as was observed in Nigeria (Jack-Ide & Uys, 2013). Additional highlights from a Nigerian study indicate that the cost of antipsychotic medicines alone accounts for more than 50% of the cost of treating schizophrenia (Suleiman, Ohaeri, Lawal, Haruna, & Orija, 1997). Also, out-of-pocket expenditures for child mental health services are 71.4% in African countries compared to 12.5% in Europe (Belfer, 2008). A study by the World Economic Forum and the Harvard School of Public Health predicted that over the next two decades, mental illness will account for the largest proportion (35%) of global economic losses from NCDs; in absolute terms, this means that the economic toll of mental illness will be over $16 trillion globally and $7.3 trillion in LMICs by 2030 (Bloom et al., 2011).
Substance Use Disorders Among Young People in WCA
The types and prevalence rates of substances used vary remarkably according to context and geographical location (e.g., youths in HICs usually use injecting drugs and other substances not commonly used by adolescents from LMICs) (Embleton, Mwangi, Vreeman, Ayuku, & Braitstein, 2013). Igwe, Ngozi, Ejiofor, Emechebe, and Ibe (2009) reported that 33.7% of 860 senior secondary school adolescents in Enugu (Nigeria) were involved in psychoactive substance abuse, while 32% and 4.1% of these adolescents had abused alcohol and used cannabis, respectively (Igwe et al., 2009). Similarly, Kayembe et al. (2008) found that 82% of street children in the Democratic Republic of Congo used marijuana, 63.5% used alcohol, and 3.8% used cocaine (Kayembe et al., 2008). Across the WCA subregion, similar or higher prevalence levels of substance abuse among senior secondary school adolescents have been reported, including in Ghana (Addo, Mainoo, Dapaah, & Babayara, 2016; Peltzer & Pengpid, 2018).
The use of illicit drugs and psychoactive substance abuse among young people is associated with severe outcomes. For instance, studies in Nigeria (among students) and in Ghana (among homeless youth) found that alcohol and substance use is associated with an increased likelihood of risky sexual behavior, with accompanied increased risk for sexually transmitted infections including HIV (Nwagu, 2016; Oppong et al., 2014). While circumstances on the street may render children and youth vulnerable to various kinds of psychological problems and health risks (Burns, Daileader, & Finger, 2004), street children using drugs and psychoactive substances are more likely to engage in crime and interpersonal violence and are also more likely to suffer traffic accidents (Doran, Luczak, Bekman, Koutsenok, & Brown, 2012).
Drivers of Mental and Substance Use Disorders in Young People of WCA
Adversities in early life are associated with increased risk of mental and substance use disorders (Kabiru, Beguy, Crichton, & Ezeh, 2010). Household and family conditions and quality of parenting also have a significant impact on risk of mental and physical health (Omigbodun, 2004). Notably, key contributors to poor mental health are broadly grouped under biological factors (e.g., age and sex), social factors (e.g., relationships with caregivers during childhood), and structural factors (e.g., poverty, urbanization, change, conflict, and natural disasters) (Allen, Balfour, Bell, & Marmot, 2014). While it is challenging to identify specific elements responsible for the onset and continuity of mental health problems, a complex interrelationship of risk factors and co-occurrence of factors exist.
In WCA, poverty is rife, as are other risk factors for mental disorders including unemployment, low incomes, poor housing, food insecurity, and low education status (Lund et al., 2010). In Nigeria, Omigbodun (2004) found that more than 50% of children at a psychiatric clinic suffering from various psychosocial stressors had experienced problems with primary support, such as separation from parents, disruption of the family, abandonment by their mother, psychiatric illness in a parent, and sexual/physical abuse in the year preceding the study. Likewise, civil conflicts, warfare, and disease have all been identified as vulnerabilities and risk factors to child and adolescent mental health in the WCA subregion (Gupta & Zimmer, 2018; Lokuge et al., 2013). Other common events during armed conflicts include sexual violence (sexual assault and rape), and the most common disorder in such settings is posttraumatic stress disorder (PTSD).
In recent years, the WCA subregion has experienced increased internal and regional displacement of people. According to UNICEF (2017b), over seven million children are on the move in West and Central Africa each year, mainly because of violence, poverty, and climate change and drought in countries such as the Central African Republic, Côte d’Ivoire, Liberia, Mali, Chad, Nigeria, and Sierra Leone. Unaccompanied migrant children are common among refugee populations, and these young children are often at increased risk of abuse, exploitation, or trafficking (UNICEF, 2017a). Studies have found that challenges of adjustment after migration in an often hostile context, history of family separation after migration, discriminatory experiences, as well as other postmigration adaptation issues (e.g., unemployment) are independently associated with depression and posttraumatic stress among migrants, who suffer from a significant burden of mental distress (Thela, Tomita, Maharaj, Mhlongo, & Burns, 2017).
A study in the Democratic Republic of Congo reported that children exposed to armed conflict presented with anxiety-related complaints (including symptoms such as stress, worry, and fear), as well as mood-related, behavior-related, and somatization problems (Lokuge et al., 2013). Moreover, in Sierra Leone, which experienced years of civil conflict, more than 7000 children were recruited as child soldiers and participated as spies, sex slaves, porters, and frontline soldiers, among other roles (Coalition to Stop the Use of Child Soldiers, 2008). Child soldiers were not only involved in the perpetration of violence but they were also often subjected to repeated physical, sexual, and emotional violence (Betancourt, Newnham, McBain, & Brennan, 2018). Betancourt et al. (2010) conducted a two-year study that followed up with former child soldiers and found increased hostility in these individuals. Similarly, youths who survived rape experienced higher levels of anxiety and aggressive behaviors but also demonstrated greater confidence and prosocial attitudes at follow-up (Betancourt et al., 2010). Children in WCA who experienced other war-related atrocities have been shown to have elevated levels of emotional distress and traumatic stress symptoms, as well as persistent bad dreams, nightmares, and intense arousal symptoms (Yoder et al., 2016). Other drivers of early mental health problems include high demands of academic performance on school children (Asare & Danquah, 2016), rapid social change and migration, social isolation, unemployment and poverty, increasing social pressures to perform well, peer pressure, individual and family crises, changes in traditional values, and conflict with parents (Burns, 2012).
Many countries in WCA have a generalized human immunodeficiency virus (HIV) epidemic (i.e., overall prevalence is 2.2% [6.1 million], with wide variation between countries, ranging from 0.5% in Niger and Senegal to 4.9% in Equatorial Guinea). The epidemic also left many children orphaned or infected in the subregion. More than 25% of children aged 0–14 years living with HIV worldwide are in the WCA subregion (Joint United Nations Programme on HIV/AIDS [UNAIDS] and UNICEF, 2016). A study in Ghana showed that orphaned or HIV-infected children suffer poor physical and mental functioning and sometimes live in isolation. Consequently, these children may develop neuropsychological dysfunction, including dementia, depression, and other disorders, which go largely untreated and lead to increased morbidity (Doku, 2016). While risk factors for mental problems in infancy and early childhood have not been widely studied, this period is the time for maximum brain growth and of formation of emotional regulatory patterns that affect later mental health outcomes (Klitzing, Döhnert, Kroll, & Grube, 2015).
Impacts of Mental and Substance Use Disorders in Young People of WCA
In the absence of any psychosocial or pharmacologic intervention to prevent or treat mental disorders, benign mental health problems among young people in Ghana and Nigeria have been shown to degenerate into grave and costly conditions, as well as social problems such as school failure, delinquency, and substance misuse (Igwe et al., 2009; Nwagu, 2016; Oppong et al., 2014; Warner & White, 2003). Poor mental health has also been associated with teenage pregnancy, HIV/AIDS, other sexually transmitted infections, interpersonal violence, child abuse, motor vehicle crashes, crime, homicide, and suicide (Doku, 2016; Doran et al., 2012; Nwagu, 2016). In addition, mental disorders are known to perpetuate a negative cycle of poverty, social exclusion, and reduced productivity, impacting the victim’s family and the broader community (Lund et al., 2010, 2011). Even with limited documentation of the impact of mental health disorders in young people of WCA, the few existing studies provide insights on trajectories for a range of mental disorders that young people experience. For instance, a recent GBD report showed that of the top ten causes of death and disability in young people, suicide and self-harm (a likely presentation of mental health problems) are leading causes of mortality among females and males aged 10 to 24 years (Mars, Burrows, Hjelmeland, & Gunnell, 2014), and 75% of global suicide deaths are in LMICs (McKinnon, Gariepy, Sentenac, & Elgar, 2016), while at the same time alcohol and drug use (also associated with mental disorders) are leading risk factors for disability-adjusted life years (DALYS) (Mokdad et al., 2016).
In the Democratic Republic of Congo, researchers concluded that mental disorders impaired school-going children’s social and educational capacities thereby affecting their school performance (Kashala et al., 2005), while in Nigeria, adolescents with higher levels of depressive symptoms have been found to experience elevated rates of school absenteeism and dropout, cultism, social violence, and engagement in other social ills (Tunde-Ayinmode, 2010). Some scholars have argued that depression may be both a catalyst and a consequence of these academic challenges (Verboom, Sijtsema, Verhulst, Penninx, & Ormel, 2014). Moreover, behavioral and emotional deviance, most common among young people with mental disorders, can lead to severe stigma and exclusion from family and communities, as found in a study in Sierra Leone (Gupta & Zimmer, 2018). Mental disorders are also linked to risky sexual behaviors, thus predisposing individuals to increased risk of HIV infections, morbidity, and mortality (Nwagu, 2016). A study in Ghana among homeless youth found that alcohol consumption was associated with four indices of risky sexual behavior (ever had sex, non-condom use, multiple sexual partners, and survival sex) (Oppong et al., 2014). In addition, heavy alcohol and substance use is associated with elevated risk of impaired brain development, brain functioning, and neuropsychological performance and long-term dependence (Adu-Gyamfi & Brenya, 2015).
Mental Health Systems and Interventions
Mental Health Systems Services for Young People in WCA
While variations exist in the availability of mental health policies, strategies, and resources across countries in WCA, mental health services are generally delivered within: (a) mental hospitals and specialist clinics, (b) psychiatric services in general hospitals, (c) mental health services through primary health care (PHC) units or integrated mental health service, and (d) community mental health services. The majority of WCA countries have limited documentation of the extent to which mental health services are available specifically for young people (either to promote positive mental health or to treat mental disorders). This is partly because many countries in the subregion (such as Liberia, Sierra Leone, and Congo) are recovering from political instabilities and protracted civil wars that degraded health systems (Jacob et al., 2007; Semrau et al., 2015). Our reviews of the WHO-AIMS survey reports available for few WCA countries (i.e., Benin [WHO-AIMS, 2007], Nigeria [WHO-AIMS, 2006], and Ghana [WHO-AIMS, 2011]), as well as Ministry of Health and WHO Atlas reports for Sierra Leone (Sierra Leone Ministry of Health, 2009) and the Democratic Republic of Congo (WHO, 2011) suggest that mental health care services targeted to young people are largely unavailable (see Table 11.2).
Available outpatient, inpatient, and community-based inpatient psychiatry services in the WCA subregion do not reflect prioritization of young people’s mental health needs. For instance, there are often no dedicated beds for adolescents and children in inpatient units and no community outreaches designed to target young people in neighborhoods and schools where young individuals typically spend most of their time. Most of the mental hospitals and mental health care staff in WCA are located in cities. Rural areas (where approximately 70% of the population resides) often lack essential mental health services. Regionally, patient-to-psychiatrist ratios are high, and in Sierra Leone, for example, there are just 0.02 specialist psychiatrists per 1000 people (Alemu et al., 2012). Importantly, within the WCA subregion, where access to professional psychiatric care is limited for most mental health patients, traditional and spiritual healers play a significant role in providing mental health services to individuals (Patel, 2011).
Mental Health Interventions Available to Young People in WCA
Several mental health interventions targeting young people have been implemented in the WCA subregion, including those that are provider-led, community-based, peer-led, and home/family/culture-based. Several local and international nongovernmental organizations (NGOs) support mental health services in the subregion by training traditional healers and non-medical personnel (e.g., in Sierra Leone), expanding access to mental health services (e.g., in Ghana) (Hushie, 2016), and providing medicines to supplement government allocations (Roberts, Mogan, & Asare, 2014). In post-conflict Liberia and Sierra Leone, local and external NGOs also partnered with governments and other international organizations such as the WHO to “Build Back Better” mental health systems (McDaid, Knapp, & Raja, 2008). Other mental health interventions have utilized a variety of platforms (i.e., schools, churches, health care facilities, and digital platforms) to tackle multiple mental issues including self-esteem, life skills, self-efficacy, resilience, and coping skills. Some interventions are population-wide, including legislation (i.e., laws to control alcohol demand and restrict its access). For example, a survey to estimate alcohol policy restrictiveness reported that Equatorial Guinea and Liberia have implemented a mix of alcohol control policies (Ferreira-Borges, Esser, Dias, Babor, & Parry, 2015). Other existing population-level interventions include policies, strategies, and regulations that are meant to establish a legal framework for mental health care services, as well as limit vulnerabilities associated with mental health problems. For example, Liberia has an official mental health policy that was reviewed in 2009 (Ministry of Health and Social Welfare, 2010). Community-wide interventions implemented in collaboration with individuals within schools, families, refugee camps, and churches also exist (Das et al., 2016).
While rigorous evidence on the effectiveness of these interventions is limited, a few studies in the subregion show a wide range of beneficial effects of mental health intervention on children, families, and communities, beyond just mental health. In the Democratic Republic of Congo, for example, brief trauma-focused therapy and counseling provided by community lay counselors to children with anxiety-related complaints led to observable behavior change, symptom reduction, and improved functioning of victims (Lokuge et al., 2013). In Ghana, a national mass media and community-level stigma-reduction program using religious leaders led to increased knowledge of HIV, reduced stigma, and improved attitudes toward people living with HIV or AIDS (Boulay, Tweedie, & Fiagbey, 2008). There is increasing interest in using schools as an opportunity to develop the foundations for positive mental health and prevent mental health problems among young people (Fazel, Patel, Thomas, & Tol, 2014).
Notably, school-based mental health interventions have been shown to create resilience, providing young people with resources to thrive and, in adverse conditions, to cope by buffering negative stressors (Oduguwa, Adedokun, & Omigbodun, 2017; Tolulope, Ani, Ajuwon, & Omigbodun, 2016). In addition, school-based interventions for mental health problems have been associated with improved social functioning, academic and work performance, and general health behaviors. Key informants in one study in Nigeria acknowledged the need for school mental health programs and identified strengths, barriers, and the core components of a successful school-based program (Ibeziako, Omigbodun, & Bella-Awusah, 2008). School-based mental health interventions can act along the entire continuum of mental health promotion and prevention and mental disorder screening/diagnosis and treatment. For example, Oduguwa et al. (2017) reported that the use of mixed-method training sessions for school children in Nigeria facilitated by the study researchers produced a positive and sustained change in knowledge and attitude toward mental illness. Likewise, Bella-Awusah et al. (2016) demonstrated that using a school-based cognitive behavioral therapy program (CBT) reduced depression symptoms among adolescents in Nigeria. The same strategy was effective among multi-symptomatic war-affected youth (aged 15 to 24 years) in Sierra Leone (Betancourt et al., 2014).
Challenges of Promoting Mental Health for Young People in WCA
Several challenges related to legislation and policy, finances and resources, organization and planning, and availability of appropriately adapted evidence-based interventions and training affect mental health promotion among young people in the WCA subregion. Underlying these factors are specific issues such as lack of data on the burden of mental disorders, unavailability of mental health services, as well as lack of trained mental health professionals and scarcity of resources (Abdulmalik et al., 2014). Data on the burden of mental disorders in young people and risk and protective factors are important to inform appropriate resource allocation and to support policies that address mental health needs. Unfortunately, data are rarely available, largely due to lack of services, absence of a national focal point for mental health services targeting young people, fragmentation in services, and lack of data collection systems. Consequently, large data gaps exist due to the asymmetrical balance between the mental disorders burden and the resources available to deal with it (Prince et al., 2007).
The high costs of mental health care also hinder the provision of quality mental health services for young people in most LMICs. Mental disorders are some of the most expensive health conditions to treat, and in most SSA countries, treatment facilities are limited and often inaccessible to much of the population (Sosso & Philippe, 2016). In settings of poverty, unemployment, and lack of medical insurance or social security, most young people experience mental disorders with very limited support. Further, whereas the WHO (through the Mental Health Gap Action Program) has recommended a range of psychosocial and pharmacological interventions for LMICs, many commonly used drugs are still not available in most WCA countries (Keynejad, Dua, Barbui, & Thornicroft, 2017).
While studies in Nigeria and Ghana have reported that mental health literacy is abysmally low among adolescents, worse are the societal and community stereotypes and prejudices resulting from misconceptions about mental illness. These misunderstandings of mental disorders have led to severe stigma in these settings (Gureje et al., 2005; Kleintjes et al., 2010). Detailed descriptions from a Togolese prayer camp, set up as a makeshift psychiatric ward, demonstrate how negative connotations and false assumptions about mental illness, as well as utter lack of any formal psychiatry services, cause individuals with schizophrenia to be locked in dark rooms and bound in chains for long unending days. Thought of as a consequence of evil spirit infestation, and most often due to an individual’s own actions, mental disorder victims suffer from societal stigma, which significantly limits opportunities for proper health care and delays their seeking of treatment services (Ronzoni, Dogra, Omigbodun, Bella, & Atitola, 2010).
Gaps in Research and Programming
Despite the WHO’s Mental Health Gap Action Plan that sought to increase the profile of young people’s mental health, virtually all WCA countries lack clearly defined policies and programs targeting young people. For instance, Nigeria lacks a child and adolescent mental health (CAMH) strategy, and CAMH issues have remained obscure to the country’s policy-makers (Atilola et al., 2014). Low prioritization of young people’s mental health by policy-makers is explained in part by the fact that mental illness has historically not been well understood (i.e., it is considered a taboo and is thought to be self-inflicted and incurable). Mental illness victims experience marked stigmatization. For a long time, traditional healers and religious actors were the source of care for mentally ill patients. These attitudes and practices are still deeply rooted in WCA populations (Aina, 2004), including among policy-makers. Consequently, this has led to negative impacts on service availability, coordination and delivery, resource allocation, and accountability (Kieling et al., 2011).
Data on the prevalence and burden of mental disorders in young people of WCA are based on small, nonrepresentative surveys. There is a need to improve surveillance and generate data (including estimates of prevalence rates and documentation of risk factors, protective factors, assessed needs, and tested interventions), to help guide areas of preventive interventions and programmatic focus to enhance mental health and well-being in the WCA countries (Jacob et al., 2007).
Efforts to improve awareness and knowledge, while reducing stigma associated with mental disorders, are critically needed, since they affect treatment-seeking behavior, symptom detection, and disclosure for early treatment. There is increasing interest in population and community-wide strategies such as social-marketing campaigns using mass media channels, social media, and social contact events to destigmatize mental disorders and reduce substance dependence (Andreason, 2004; Sampogna et al., 2017; Scheier & Grenard, 2010). These approaches could potentially reduce stigma and elicit positive attitudes among young people with regard to mental health problems. Also, there is a need for research to gain a deeper understanding of the variations in gender with regard to the burden and drivers of poor mental health, as well as the applicable gendered interventions. More evaluation research is needed to decipher important dimensions of public mental health interventions, such as their reach, effectiveness, adoption, implementation, and maintenance over time. While several interventions have been reported to have positive effects in the WCA subregion, very little is known about the extent to which these findings are appropriate to other settings.
Implications for Research and Programming on Mental Health of Young People
With limited existing data and in the absence of needs assessments to identify gaps and areas of action to enhance access, quality, and availability of mental health care for young people in the subregion, mental health care remains a relatively low priority. Improving the available unmet needs data would create a basis for investment in young people’s mental health and monitoring and evaluation of these investments. Awareness of mental health is dismally low across the population (including among health care workers and policy-makers), further reflecting the low attention accorded to mental health. Employing wide population-based education and awareness strategies with a broader reach, such as social-marketing approaches employed via social media channels, mass media, and mobile phones, could reach large numbers of people simultaneously and could potentially reduce stigma associated with mental health and improve awareness.
Research is also needed on how to scale up existing mental health services targeting young people, especially the vulnerable individuals in remote settings, with limited access to services. Potential approaches to scale up these services include availing services for young people within the current mental health facilities (e.g., by increasing bed capacities reserved for children/adolescents within inpatient care units); supporting capacity building of the professional staff (e.g., nurses and doctors) and informal staff (e.g., lay workers, community health volunteers, and non-specialists); and incorporating ideas such as task-shifting and task-sharing to address large numbers of patients (whose mental health problems are not severe). With respect to task-shifting, research is needed on the possible use of non-specialist health care providers to screen and refer young people to physicians. Further research is also needed on the development of tools for screening and diagnosis, as well as protocols for treatment, low-cost treatments and therapies, and the integration of mental health care packages within primary health care (PHC) services, to take advantage of already existing service delivery platforms and leverage their resources (such as staff, data collection systems, and referral pathways).
Conclusion
In this study, we sought to understand the burden of mental and substance use disorders, their drivers, and their impacts among young people in WCA. Our review of the literature showed that the prevalence of mental disorders among young people ranged between 12% and 30% in the WCA subregion, with conduct, anxiety, and depressive disorders being the most common disorders. In line with previous studies (Bradley, 2001), we found gendered differences in the epidemiology of poor mental health, with adolescent girls being more vulnerable to depression than boys. A significant number of young people in primary and secondary schools were reported to use substances such as marijuana and cocaine, with a majority involved in alcohol abuse. There was a significant variation in the prevalence of mental disorders among young people across the WCA subregion. These differences may be explained by the heterogeneity in the methodologies used to diagnose mental health problems and varying degrees of exposures to risk factors and protective factors.
Multiple factors drive poor mental health and substance use disorders in young people in WCA. More worrying is the co-occurrence of risk factors for mental health problems, including social factors (such as poor family relations) and structural factors (e.g., poverty, high unemployment, urbanization, rapid social and economic change, conflict, and natural disasters) in these settings (Allen et al., 2014). The co-occurrence of these risk factors increases exposure to the stressors that precipitate the onset and continuity of mental health problems. Untreated mental disorders may result in severe negative consequences, the most serious of which is suicide. For instance, depression has been found to be the strongest single risk factor for attempted or completed suicides (Beautrais, Joyce, & Mulder, 1996). Apart from worsening the livelihoods of young people, poor mental health may predispose young people to infectious diseases (such as HIV) or worsen outcomes for diseases (such as TB) because of increased propensity to engage in risky sexual behavior and poor adherence to treatment among those with mental health and substance disorders (Nwagu, 2016; Oppong et al., 2014).
Despite the burden and impact of mental disorders among young people in WCA, programming for these key populations remains insufficient, and lack of policy, limited resources, stigma, discrimination, and socioeconomic barriers may prevent many people from accessing mental health care. Several psychosocial and pharmacological interventions (along the continuum of primary, secondary, and tertiary prevention) for mental and substance use disorders have been described in many LMICs, including WCA (Barry et al., 2013). However, data on the effectiveness of these interventions is weak or lacking, yet such evidence is critical to inform scale-up of interventions. Systematic reviews of school-based interventions from HICs (and few from WCA) show they have great potential to facilitate early detection and management of mental disorders in young people, with positive effects not only on mental health, but also on academic and work performance and general health behaviors (Fazel et al., 2014). Increasing school enrollment rates could place schools as an optimum entry point for most early mental health interventions for young people (UNICEF, 2014). Early identification and treatment of mental and substance disorders are essential. Studies in the United States and Brazil have shown that early initiation of treatment leads to decreased morbidity and mortality, including the reduction in suicidal thoughts and behaviors (March et al., 2009). Schooling also improves self-esteem, problem-solving and social skills, positive thinking, good physical health, educational opportunities, positive parenting, and availability of social support systems, which can positively modify individual response to psychosocial stress (Opler, Sodhi, Zaveri, & Madhusoodanan, 2010).
Further research is required to improve evidence on the burden and impact of mental health problems among young people in the WCA subregion. In particular, research is needed to identify young people who may be especially vulnerable to poor mental health including those in conflict and post-conflict settings, those living with chronic illness, sexual minorities, and homeless youth. Studies investigating the utilization of mental health services by young people and effective and scalable mental health interventions are also needed. With respect to the latter, our findings underscore the need for programmatic investment toward training of primary health care workers on mental health care and community-based mental health care services for young people.
In conclusion, the lack of data on the burden, drivers, and impact of mental disorders, as well as the utilization of mental services by young people in the WCA subregion, acutely hampers any action to improve mental health care for young people. A fair amount of evidence exists on mental health interventions amenable for scale-up for young people in the subregion; however, further research is required to elucidate other dimensions of these interventions such as cost effectiveness. There is a need for programmatic focus by WCA governments, donors, and other stakeholders on training of mental health care providers and the provision of quality of mental health services to young people. An integrated approach to the delivery of mental health services that includes a focus on schools, communities, households, and other settings where youth participate actively would be key to reaching the most vulnerable young people with much needed care and services.
