Food insecurity and common mental disorders in perinatal women living in low socio-economic settings in Cape Town, South Africa during the COVID-19 pandemic: a cohort study

Abstract Objective: Common mental disorders (CMDs) such as depression and anxiety are highly prevalent during the perinatal period, and are associated with food insecurity, domestic violence and lack of social support. This study explores the relationship between household food insecurity, mental health status and several adverse social and economic factors experienced by perinatal women during the COVID-19 pandemic.Design: Cohort study, using telephonic interviews at two time-points, three months apart. Logistic regression analysis was used to model the associations of several baseline risk factors with the occurrence of household food insecurity at follow-up as the outcome.Setting: Midwife obstetric units or basic antenatal care units in Cape Town, South Africa.Participants: The sample comprised of 880 perinatal women at baseline and 660 women at follow-up. Results: At baseline 23% were pregnant, 54% were unemployed, 13% had a probable CMD, 43% were severely food insecure and 21% experienced domestic abuse in the past year. Of the 660 women interviewed at follow-up, 71% were unemployment, 3.5% were pregnant, 7% had a probable CMD, and 32% were severely food insecure. In the multivariate regression model, after controlling for ethnicity, number of children, being HIV-infected, and having a planned pregnancy, the odds of being food insecure were greater in women who were unemployed (OR=1.88; p=0.001) or had probable CMD (OR=2.20; p=0.019) at baseline. Conclusions: This study highlights a range of socio-demographic and mental health related variables that predict food insecurity among perinatal women during the COVID-19 pandemic.
