Abstract
Purpose
This study aims at determining the risk of physical inactivity and sedentary behaviors on overweight and obesity among primary school children aged 10–13 years in Tanzania.
Design/methodology/approach
A case-control study was conducted from January to March 2020 involving 69 overweight/obese children as cases and 138 normal weight children as controls. Cases were identified as having body mass index-for-age ≥ +1 standard deviation (SD) and controls as those having BMI-for-age range between −2 SD to <+1 SD. A validated questionnaire was used for data collection on daily physical activities and sedentary behavior types, frequency duration and activity score. An independent sample t-test was used to compare means of activity score between cases and controls. Binary logistic regression was used to predict risk factors for overweight/obesity.
Findings
Risk factors for overweight/obesity were listening to music and/or radio for >2 h/week (OR 2.7, 95% CI 1.2–6.1) and walking for exercise <2 h/week (OR 2.1, 95% confidence interval [CI] 1.1–4.1). On the other hand, rope skipping for >2 h/week (OR 0.14, 95% CI 0.03–0.7) was a protective factor against overweight/obesity. Controls had a significantly higher mean score of being active during lunch breaks compared to cases (p = 0.012). Cases had higher weight, height and percentage body fat than controls (p < 0.001). The home environment provided more avenues for physical activity than the school environment.
Originality/value
To the best of the authors’ knowledge, this is original research work and the first case-control study to predict physical activity and sedentary behaviors as risk factors for overweight and obesity in Tanzanian school children.
