Dietary Habits and Determinants of Overnutrition Among Secondary and Preparatory School Adolescents: A Multi-Center...

Background: Overnutrition is characterized by abnormal or excessive fat buildup in the body's fatty tissue, leading to potential health issues associated with overweight or obesity. These conditions pose significant public health challenges for adolescents and are strong indicators of future obesity, illness, and even death. As a result, this study sought to examine the dietary behaviors and factors contributing to overnutrition in secondary and preparatory school students in Debre Berhan Town, Ethiopia. Methods: An institutional-based unmatched case-control study was conducted among 285 adolescents from March 18 to April 20, 2021. The data collection was carried out using standardized interviewer-administered semi-structured questionnaires, which were adapted from previous studies. A general survey was conducted to identify cases and controls. The cases and controls were selected using simple random sampling methods. Data was entered using Epi-data 4.2 software and exported to SPSS v25. Descriptive statistics were done based on the nature of the data. Bivariable and multivariable logistic regression analysis was performed. World Health Organization AnthroPlus software was used to analyze anthropometric data into body mass index for age with z-score. Adjusted odds ratio with a 95% confidence interval and P-value <.05 was considered statistical significance. Result: In this study, eating habits while reading (AOR = 3.87;95% CI: 1.95-7.686), sedentary behavior, (AOR = 2.52; 95% CI: 1.278-4.97), vigorous type of physical exercise for <75 min per week (AOR = 2.38; 95% CI: (1.149-4.92), <6 sleeping hour per day (AOR = 5.68; 95% CI: 2.08-15.48) and earning an average family income of ≥227 USD (AOR = 2.67; 95% CI: 1.214-5.9) were significantly associated with overnutrition among school adolescents. Conclusion: Overnutrition is a significant emerging public health concern among school adolescents, with various factors contributing to its prevalence. This study underscores the importance of promoting an active lifestyle, reducing sedentary behavior, and fostering healthy eating habits as crucial national public health priorities. Early interventions targeting modifiable risk factors are essential for mitigating the incidence of overnutrition among adolescents. It is recommended that educational programs addressing overnutrition and its associated health implications commence early in school settings to prevent the escalating prevalence of this issue. Public health initiatives aimed at increasing awareness of risk factors for overnutrition among adolescents are warranted to alleviate the future burden of obesity-related chronic non-communicable diseases.
