Gender difference in the point prevalence, symptoms, comorbidity, and correlates of depression: findings from the Lagos State Mental Health Survey (LSMHS), Nigeria.

It is still unclear whether the gender difference in the rate of depression cuts across cultures or is specific to some depressive symptoms. This study evaluated the gender difference in current prevalence, symptoms, comorbidity, and correlates of depression in Lagos, Nigeria. A total of 11,246 adult participants (6525 females and 4712 males) in a face-to-face household survey were assessed for symptoms of depression. They were also assessed for symptoms of anxiety, somatic symptoms, alcohol and substance use disorders, and disability. The difference between the point prevalence for symptoms of depression in females (6.3%, s.e 0.3) and males (4.4%, s.e 0.3) was significant (OR 1.28, 95% CI 1.14-1.59). Compared to males, females had significantly higher rates for anhedonia (OR 1.20), hypersomnia (OR 2.15), fatigue (OR 1.49), guilt/worthless feeling (OR 1.41), poor concentration (OR 1.32), psychomotor retardation (OR 1.51), and suicidal ideation (OR 1.32). However, poor appetite (OR 0.69) and comorbidity with alcohol use (OR 0.25) was significantly lower in females compared to males. The significantly higher rates for depression in females were only restricted to below 45 years and higher socioeconomic status. Our study further contributed to the growing literature suggesting that the gender differences in rates of depression not only cut across many cultures, but most pronounced with atypical symptoms, not affected by recall bias and seems to disappear with increasing age. These need to be considered when formulating mental health policies for equitable and acceptable health services.

Current prevalence, comorbidity and associated factors for symptoms of depression and generalised anxiety in the Lagos State Mental Health Survey (LSMHS), Nigeria.

BACKGROUND: Depression and anxiety are very prevalent, highly co-morbid, burdensome with huge treatment gaps in low and middle-income countries (LMICs). This study aimed to estimate the current prevalence of symptoms of depression and generalised anxiety, examine co-morbid conditions and associated sociodemographic factors in Lagos state, Nigeria. METHODS: A face to face household survey completed by 11,246 adult participants (age 18-75years). Clinically significant symptoms of depression, generalised anxiety and somatic symptoms were assessed using the specific modules of the Patient Health Questionnaire (PHQ) respectively. Alcohol use, substance use and disability were assessed with the Alcohol Use Disorders Identification Test-short form (AUDIT-C), the Mini International Neuropsychiatric Interview (M.I.N.I) and the WHO Disability Assessment Schedule (WHODAS 2.0) respectively. RESULTS: The mean age was 36.75 (sd 12.3) years and there were 6525 (58.0%) females. The weighted current prevalence of symptoms of depression, generalised anxiety and combined depression/generalised anxiety were 5.5% (se 0.3), 3.5% (se 0.2) and 1.2% (se 0.1) respectively. About 20.9% of all cases of depressive symptoms have co-morbidity with symptoms of generalised anxiety. Symptoms of depression and generalised anxiety had high co-morbidity with somatic symptoms, alcohol use problems and disability but not substance use disorders. Being female, not married (especially separated/divorced or widowed) and unemployment were significantly associated with presence of either symptoms of depression or generalised anxiety. CONCLUSION: Our findings suggest that despite the popularity of cross-national surveys, there is need for individual countries and states to generate complimentary local data to plan effective local response to close the huge treatment gap for common mental disorders.

Prevalence and associated factors for suicidal ideation in the Lagos State Mental Health Survey, Nigeria.

BACKGROUND: To combat the increasing rate of suicide, basic data on suicidal behaviours reflecting the uniqueness of the locality are needed in sub-Saharan Africa. AIMS: To assess the prevalence of suicidal ideation and associated factors. METHOD: Adults (n=11 246) from the five administrative divisions of Lagos State completed questionnaires detailing suicidal ideation, socio-demographic details, common mental disorders (depression, anxiety and somatic symptoms), alcohol and psychoactive substance use disorders and disability. RESULTS: The weighted prevalence of current suicidal ideation was 7.28% (s.e. 0.27). Independently associated factors were older age, being female, not married, low occupational group, depression, anxiety, somatic symptoms and disability. CONCLUSIONS: Despite the validity of cross-national surveys, there is need for individual countries to generate complementary local data to explain variability in rates and risk factors in order to plan for suicide prevention or develop timely and effective response.

Addressing the mental health needs of a rapidly growing megacity: the new Lagos Mental Health Initiative.

The Lagos State Government of Nigeria recently launched its Mental Health Policy and Work Plan aimed at addressing the mental health needs of Lagos, one of the world's fastest-growing megacities, and its nearby communities. This paper discusses the contextual basis of this initiative, its components and the challenges faced so far. It argues that urban centres deserve attention in the current push towards investing in mental health services in low- and middle-income countries.

Provision of mental health services in Nigeria.

Nigeria, like other African countries, is short of personnel trained in mental healthcare. Efforts to tackle the problem have often focused on increasing the numbers of psychiatrists and nurses in the field. These efforts, over the past 20 years, have not appeared to have greatly improved service delivery at the grass roots. Most of the specialist centres where such highly trained personnel work are in urban areas and for a large part of the population access to them is limited by distance and cost.

Nosology and modalities for deciding on the management of patients with psychiatric illness among traditional healers in Lagos, Nigeria.

Many patients in Nigeria consult traditional healers before, or in parallel with, modern psychiatric services. Part of the attraction of traditional medicine for the populace, apart from its lower cost and easier accessibility, may lie in its 'cultural' explanatory concepts of the nature and course of mental disorder.
