Associations Between Self-Perceived Psychosocial Stress and Markers of Adiposity in Ga Mashie, Urban Ghana: Evidence from a Cross-Sectional Population-Based Survey

Prior research from Ghana suggests psychosocial stress is associated with lower body mass index (BMI) and waist circumference (WC), both markers of adiposity, contrasting with meta-analyses showing positive associations in other settings. This study aimed to explore how stress was associated with markers of adiposity in urban Ghanaian adults. Data included 854 adults from the Contextual Awareness, Response and Evaluation Diabetes in Ghana survey carried out in November–December 2022 in Ga Mashie, a deprived area of the capital Accra. Associations between self-perceived stress (Perceived Stress Scale 10, categorized into low and average–high stress) and BMI or WC-for-height ratio (WHR) were assessed using linear regression. Results were adjusted for survey design and confounders and stratified by sex. Greater stress was associated with higher BMI and WHR in females (adjusted coeff. [95% CI]: BMI: 2.3 [0.5, 4.0], WHR: 0.03 [0.00, 0.06]). No associations were found in males. These findings highlight the need to understand the complex interactions between gender, stress, and increasing burdens of obesity and other associated non-communicable diseases in urban African settings, with a view to designing context-specific interventions to reduce risk.
