Correlation between screen time, sleep duration and body mass index in school going children - A cross-sectional study

Abstract

Background: Obesity among children and adolescents has emerged as a major global health issue in recent years. The relationship between body mass index, screen time, and sleep length was found to have both good and negative effects on school-age children. Objectives: To determine the correlation between Body mass index, Screen time, Sleep duration. Method: In this cross-sectional study, school-age children's BMI, screen time, and sleep length were examined. 62 students in all participated in this study. A non-parametric test was employed to determine correlation because the data was not regularly distributed. Analysis and Spearman's rho correlation test were performed. Results: As the data was not normally distributed, a non-parametric test was used for correlations between BMI and screen time shows p value >0.05 (0.105) and r value -208. BMI and sleep duration shows p value 0.05 (0.085) and r value -221 is obtained; spearman’s rho test was used. Conclusion: Mild negative correlation has been found between BMI-Screen time, and Screen time-Sleep duration, and mild positive correlation between BMI-sleep duration in school going children but it was not statistically significant. Mild negative correlation has been found between BMI Screen time and Screen time-Sleep duration.
