Gadget addiction among school-going children and its association to cognitive function: a cross-sectional survey from Bangladesh

BackgroundPeople are becoming more dependent on technology than ever before. Today's children and adults are heavily plugged into electronics, which raises concerns for their physical and cognitive development. This cross-sectional study was conducted to assess the relationship between media usage and cognitive function among school-going children. MethodsThis cross-sectional study was conducted in 11 schools in 3 of Bangladesh's most populous metropolitan areas: Dhaka, Chattogram and Cumilla. A semistructured questionnaire with three sections was used to obtain data from the respondents: (1) background information, (2) PedsQL Cognitive Functioning Scale and (3) Problematic Media Use Measure Short Form. Stata (V.16) was used for statistical analysis. Mean and SD were used to summarise quantitative variables. Qualitative variables were summarised using frequency and percentage. The chi(2) test was used to explore bivariate association between categorical variables, and a binary logistic regression model was fit to investigate the factors associated with the cognitive function of the study participants after adjusting for confounders. ResultsThe mean age of total of 769 participants was 12.0 +/- 1.8 years, and the majority (67.31%) were females. The prevalence of high gadget addiction and poor cognitive function was 46.9% and 46.5%, respectively, among the participants. After adjusting the factors, this study found a statistically significant relationship (adjusted OR 0.4, 95% CI 0.3 to 0.7) between gadget addiction and cognitive function. In addition, the duration of breast feeding was a predictor of cognitive function as well. ConclusionThis study found digital media addiction as a predictor of decreased cognitive performance in children who use digital gadgets regularly. Although the cross-sectional design of the study precludes causal relationships from being determined, the study finding deserves further examination via longitudinal research.

Automated summary

This study aimed to assess the relationship between media usage and cognitive function among school-going children. A cross-sectional study was conducted in three populous metropolitan areas in Bangladesh, and the findings showed a significant association between gadget addiction and decreased cognitive performance in children who regularly use digital gadgets.
