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.
