Objectively Assessed Physical Activity and Associated Factors Among Adults in Peri-Urban and Rural Eastern Uganda: A Population-based Study.

BACKGROUND: Data on physical inactivity, a known risk factor for noncommunicable diseases and its correlates in sub-Saharan Africa are almost absent. We assessed physical activity patterns and associated factors among adults. METHODS: A populationbased study of 1208 adults was conducted in the Iganga-Mayuge Health and Demographic Surveillance Site, Uganda. Physical activity was assessed using a pedometer for 7 days. Physical inactivity was defined as a daily average of < 7500 steps while sedentary behavior was defined as a daily average of < 5000 steps. Logistic regression was conducted to identify factors associated with physical inactivity and sedentary behavior. RESULTS: Of the 1208 participants, 18.8% were sedentary (10.6% of men; 26.9% of women, P < .001), 37.6% were physically inactive (28.5% of men; 46.6% of women, P < .001). Factors associated with sedentary behavior were being female, ≥ 65 years, peri-urban residence, being a domestic worker, formal employment and lower primary education. Factors associated with physical inactivity were being female, 55 to 64 years, ≥ 65 years, peri-urban residence, overweight and obesity. CONCLUSIONS: Sedentary behavior and physical inactivity were prevalent among the adult population. Targeted physical activity promotion interventions are needed.
