Factors associated with self-reported diagnosis of depression in Kenya: insights from 2022 Demographic and Health Survey.

backgroundMental health issues, particularly depression, have seen a significant increase worldwide in recent years, raising global concern. Depression is projected by the World Health Organization to become the leading cause of mental illness by 2030. This condition severely impacts the quality of life and psychosocial functioning of those affected, underscoring the need for effective interventions and awareness. The 2022 Kenya Demographic and Health Survey is the first Demographic and Health Surveys in Africa to incorporate the mental health diagnosis module. Therefore, this study assesses socio-economic, demographic characteristics and health conditions associated with depression in Kenya.

methodsThis secondary analysis uses data from the 2022 Kenya Demographic and Health Survey, in which participants were selected from households within designated demographic surveillance areas across Kenya. A two-stage cluster sampling method was applied to achieve national representativeness. The study examined associations between socio-demographic characteristics that included age, gender, education level, marital status, household wealth index, and urban/rural residence, as well as chronic diseases such as heart and lung diseases, hypertension and diabetes, and self-reported depression using logistic regression analysis. Both crude and adjusted odds ratios (ORs) for self-reported depression were assessed, with statistical significance set at a p-value of [Formula: see text]. Additionally, spatial analyses of self-reported depression prevalence were conducted to identify regional patterns.

resultsA total of 31354 men and women were assessed. The prevalence of self-reported depression was 2.6%. Being a middle-income earner was associated with increased likelihood of depression (aOR:1.12, 95% CI: 1.03-1.22). Being hypertensive, diabetic, and having heart and lung diseases increased the likelihood of having depression by at least two-fold, (aOR:3.71, 95% CI: 3.49-3.95, aOR:1.14, 95% CI: 0.96-1.35, aOR:3.10, 95% CI: 2.68-3.57 and aOR:3.21, 95% CI: 2.84-3.62, respectively).

conclusionThe proportion of participants who self-reported depression was low. Besides, there was a considerable variation in self-reported depression across different counties in Kenya. Furthermore, there was variability in depression among different socio-demographic groups. Therefore, there is a need to target mental health interventions to persons with chronic conditions and those in middle economic class as they are greatly affected with depression.
