Population-based cross-sectional study of the correlation of physical inactivity and sedentary behaviour with sociodemographic factors among Bangladeshi adults.

Background: Physical inactivity and sedentary behaviour are influenced by various interconnected variables. In Bangladesh, studies on physical inactivity and sedentary behaviour are scarce, regardless of age in the adult population. This study aims to determine the correlates of adults' physical inactivity and sedentary behaviour with sociodemographic factors, including gender, age, residential, educational, and occupational status.

Methods: This is a secondary analysis of a cross-sectional survey conducted from February to May 2018 across eight divisions of Bangladesh. Global Physical Activity Questionnaire was used to measure physical inactivity and sedentary behaviour. The data consisted of 8,185 adults aged 18 to 69 years. The Bayesian regression model was used to analyse the correlates.

Results: Physical inactivity, including work, active transport, and recreation, males and urban residents were more likely to be inactive than their female counterparts and rural residents. Married adults had greater (Odd Ratio [OR]: 6.6, 95% CI: 5.46 to 7.98) recreation-related physical inactivity. Unemployed adults were more likely to engage in sedentary behaviour (OR: 4, 95% CI: 2.48 to 6.12) and less likely to engage in moderate physical activity (OR: 2.2, 95% CI: 1.43 to 3.39).

Conclusions: A notable pattern of insufficient recreational physical activity among adults in Bangladesh was noted. Establishing nationwide surveillance systems to detect physical activity and sedentary behaviour trends to evaluate potential interventions for improving physical activity and reducing sedentary behaviour. Expanding school-based physical activity programs help children and adolescents learn lifelong healthy behaviours. Community sports programs for all ages promote active living.
