Determinants of overweight and/or obesity among school adolescents in Butajira Town, Southern Ethiopia. A case-control study

Abstract

Background: The global rise of adolescent overweight and obesity is posing a new challenge to the public health sector by determining the forthcoming generation for the most awful and upsetting quality of social life by inducing bantering, social isolation, and stigmatization among children that contribute to the mental wellbeing of the growing adolescents. Risk factors for overweight and/or obesity might not be the same across different regions due to differences in socioeconomic characteristics, culture, ethnicity, and geographical location. Moreover, in this study area, no report has been documented so far on the determinant factors of overweight and/or obesity among school adolescents. Hence, this study aimed at identifying context-specific determinants of overweight and/or obesity among adolescents in the study area.

Methods and materials: School-based unmatched case-control study design was employed from March 1-30, 2019, in Butajira town, Southern Ethiopia. Data were collected regarding sociodemographic, dietary practice, physical activity, nutritional knowledge-related factors, and anthropometric measurements. Multivariable logistic regression models were fitted to identify independent predictors of overweight/obesity.

Results: We enrolled 297 adolescents: 99 cases, 198 controls. Multivariable binary logistic regression analysis revealed that those in high socioeconomic status [AOR = 5.8, 95% CI (2.66, 12.5)], consumed soft drinks 3 and above times per week [AOR = 3.7, 95% CI (1.8, 7.3)], physically inactive [AOR = 4.4 95% CI (1.68, 11.6)], spent free time by watching television/movies for 3 and above hours per day [AOR = 8.6, 95% CI (4.3, 17)] and with poor nutritional knowledge [AOR = 3.4, 95%CI (1.7, 6.9)] were significantly associated with overweight and/obesity.

Conclusion: High socioeconomic status, consumption of soft drinks, physical inactivity, sedentary behavior, and poor nutritional knowledge were significantly associated with overweight/obesity. Therefore, strengthening parent and school-based health education in healthy nutrition behaviors and promotion tactics such as enhancing physical activity, limiting watching television, and soft drinks will be helpful to minimize overweight and obesity among adolescents.
