Objectives To assess the sex-specific status of dietary diversity (DD) and its associated factors among older men and women (aged ≥60 years) in Bangladesh. Design A nationally representative cross-sectional survey was conducted in 2018–2019 on food security, nutrition and health of older adults of both sexes. Setting Data were collected from 82 clusters (rural 57, non-slum urban 15 and slum 10) from all eight administrative divisions of Bangladesh. Participants A total of 4817 participants aged ≥60 years (2482 men and 2335 women) were enrolled. Measures A list-based (24-item) recall method was employed, and the items were later aggregated into 10 food groups. The outcome variable was the prevalence of inadequate DD, defined as consumption of less than 5 food groups out of 10. Results Men and women had mean DD scores of 4.33±1.6 and 4.13±1.7, respectively. Women had a higher prevalence of inadequate DD than men (61.2% vs 56.3%, p=0.028). Among the food groups, women consumed significantly less fish and eggs than men (fish: 50.96% vs 57.76%, p=0.002; eggs: 17.13% vs 22.10%, p=0.004). Poor education, rural dwellings, living in homes with fewer individuals and living in food-insecure households were associated with inadequate DD in both sexes. Furthermore, among men, older age and not being currently married, and among women, lower age and living in households with middle wealth status were associated with inadequate DD. Conclusions The study found that older women consume relatively less diverse diets than men, and several sociodemographic factors influence inadequate DD among older adults of both sexes in Bangladesh. These factors should be considered while developing policies and programmes to promote equitable access to a diversified diet and improve geriatric health and nutritional outcomes.
