Abstract

BACKGROUND AND AIMS: Internet-related disorders for example, internet addiction (IA) seem to be frequent among adolescents all over the world. However, there could be a possible link between body mass index (BMI) and the risk of eating disorders (EDs) in connection with IA. This study aimed to determine the relationship between risk of EDs, BMI, and IA among Bangladeshi adolescents, as well as factors associated with IA.

METHODOLOGY: A cross-sectional study was carried out among 2147 individuals, using a stratified random sampling method, aged 13-19, from various selected schools and colleges spread across Bangladesh using a Google form questionnaire consisting of sections on socio-demographic factors, body mass index (BMI), eating attitude test scale, and internet addiction test scale. Descriptive analysis, Pearson Chi-square test, logistic regression model, and a bivariate correlation analysis were fit to determine the relationship and factors.

RESULTS: We found that 24.1% of students had IA, 23.2% were at risk of EDs, 6.6% were underweight, 1.9% were overweight, 24% were obese and the remainder were normal. The relationship between IA, BMI, and risk of EDs was significant and positively co-related. Moreover, we found gender, the purpose of internet use, daily internet usage, physical exercise, literature reading habits, and victims of bullying were significantly associated with IA.

CONCLUSION: The findings highlight the need for further research and strategies to diagnose and treat EDs and IA, among adolescents. Promoting physical activity, healthy habits, and awareness at the institutional and parental levels is crucial for mitigating these risks and addressing sociodemographic, internet usage, and emotional health factors.
