Prevalence and social determinants of anxiety and depression among adults in Ghana systematic review

Abstract

Abstract Background Anxiety and depression are major public health concerns, yet their prevalence and social determinants contributing to mental health disparities remain underexplored. This review, to our knowledge, is the first of its kind, aiming to examine the prevalence of anxiety and depression symptoms and disorders among adults in Ghana, along with social determinants associated with their occurrence. Methods A search of nine electronic databases and seven grey literature sources was conducted up to September 25, 2023. Two reviewers independently screened and appraised the studies. Forty-six studies were included. Prevalence estimates were pooled using a random-effects model. Subgroup analysis and meta-regression explored potential moderators. A narrative synthesis explored social determinants associated with anxiety and depression. Results Preliminary results showed a high prevalence of anxiety (43.7%, 95% CI: 35.6-54.4%) and depression (37.8%, 95% CI; 32.5% to 46%), with regional variations. There were significant differences in the prevalence of anxiety and depression across chronic physical conditions and method of condition assessment. Meta-regression showed significant association between average age and anxiety prevalence. Social determinants associated with anxiety included being female, non-Christian, low income, self-employed, limited social support, and basic education, while that for depression included being young (< 25yr), low income, government employed, childhood physical and sexual abuse, gender-based violence and urban residence. Protective factors for both were male gender, strong social support and higher education. Conclusions Preliminary results indicate a high prevalence of anxiety and depression linked to social determinants. While methodological limitations exist (eg, study heterogeneity), findings highlight a need for evidence-based interventions targeting social determinants to reduce the burden of anxiety and depression among adults in Ghana. Key messages • Our review suggests addressing the social determinants of mental health, aligned with sustainable developmental goals, may reduce the burden of anxiety and depression. • While Ghana is working towards improving mental health via its revised 12year Mental Health Policy launched in 2021, this review can facilitate planning and resource allocation for mental healthcare.
