Anxiety and sleep mediate the effect of food insecurity on depression in single parents in Ghana.

BACKGROUND: Data on the association between food insecurity and depression in single parents in low- and middle-income countries (LMICs) are limited, and no study has reported the serial mediation effects of psychosocial factors in this association. This study examines the extent to which anxiety and sleep serially explain the food insecurity and depression link among single parents in Ghana. METHODS: Data on 627 single parents were obtained through a multi-stage stratified sampling technique. Food insecurity was assessed using the Food and Agriculture Organization Food Insecurity Experience Scale (FIES), and depression was assessed using the Center for Epidemiological Studies Depression Scale (CES-D-10). Multivariable OLS models and bootstrapping serial mediation analyses were performed to evaluate the hypothesized associations. RESULTS: The mean age (SD) was 45.0 (14.7) years; 67.3% females. After full adjustment, food insecurity was significantly associated with increases in anxiety symptoms (ß = 0.61, 95%CI = 0.476 - 0.737), sleep problems (ß = 0.04, 95%CI = 0.02 - 0.07), and depression (ß = 0.24, 95%CI = 0.12 - 0.36). Food insecurity indirectly related to depression via anxiety (ß = 0.35, 95%CI = 0.26-0.44) representing 55.8%, sleep (ß = 0.03, 95%CI = 0.0032-0.0575) suggesting 4.0%, and anxiety→sleep (ß = 0.013, 95%CI = 0.0024-0.0265) yielding 2.0% of the total effect. CONCLUSIONS: Food insecurity was positively associated with depression. This association was partially and serially explained by generalized anxiety and sleep problems. Efforts to address depression among single parents should consider interventions for food insecurity and psychosocial problems, particularly in LMICs.

Meeting the WHO Physical Activity Guidelines is Associated With Lower Odds of Depression in Older Adults: Potential Psychosomatic Mechanisms.

OBJECTIVES: Limited data exist on the association between physical activity (PA) and depression in older adults from low- and middle-income countries (LMICs). In this study, we examine the association between meeting the World Health Organization (WHO) PA guidelines and depression in adults aged ≥50 years in Ghana and investigate the psychosomatic factors explaining this association. METHODS: Cross-sectional data from the Aging, Health, Psychological Well-being, and Health-seeking Behavior Study in Ghana (2016-18) were analyzed. Depression was assessed with the Center for Epidemiological Studies Depression Scale (CES-D-10). PA was assessed using the International Physical Activity Questionnaire Short Form (IPAQ-SF). Multivariable logistic regression and Hayes PROCESS macro with bootstrapping mediation analyses were performed to evaluate the hypothesized associations. RESULTS: The study included 1201 individuals (mean [SD] age 66.1 [11.9] years; 63.3% women). The prevalence of meeting PA guidelines and depression was 36.7% and 29.5%, respectively. Meeting the WHO-recommended PA guidelines was associated with a 16% lower rate of developing depression even after adjusting for potential confounders (OR = 0.84, p <0.001). This association was much stronger among men and those aged 50-64 years. Loneliness, social isolation, sleep problems, functional limitations, and pain characteristics largely mediated the association of PA with depression. CONCLUSIONS: PA was negatively associated with depression among older adults in Ghana, and psychosocial and physical factors partially explained the association. The promotion of PA in old age may aid in the prevention of depression, especially in men and those aged 50-64 years. Longitudinal data may confirm our findings.
