High screen time and associated factors among high-school students in an urban setting of Kerala: a cross sectional study

Abstract

Background: Screen time (ST) is the time spent in sedentary behaviors involving screen based media (SBM) like watching television, playing games, using computers and mobile phones. This situation is a matter of concern because excessive screen time is associated with the risk of excess weight gain, hypertension, metabolic syndrome, low cardiorespiratory fitness. In a study conducted in urban resettlement in New Delhi, 68% of adolescents engage in using SBM for more than 2 hours. This study aimed to estimate the prevalence of excess screen time and factors associated with it among school going adolescents in Kerala.Methods: A cross sectional study was conducted among 130 students of age group 12-15 years studying in schools located in urban area of Thiruvananthapuram district from August 2019 to October 2019. Stratified sampling technique was used. A semi-structured self-administered questionnaire was used for data collection. Data was entered in MS Excel and was analyzed using appropriate statistical software.Results: The proportion of students who had high screen time was 87.7%. Mobile phones were the most frequently used gadget. Male gender OR-8.3 (95% CI- 1.7-40.3), less duration of sleep OR-0.34 (95% CI- 0.15-3.12), and low socio-economic status OR-0.21 (95% CI- 0.21-0.96) were found to be associated with high screen time among high school students in Kerala.Conclusions: The study observed that 87.7% of high school students engage in using Screen based media for more than 2 hours. In this study male gender and short sleep duration were found to be associated with excess screen time.
