Lifestyle modification in school-going children before and after COVID-19 lockdown.

PURPOSE

To evaluate the impact of COVID-19 lockdown restrictions on lifestyle of school-going children.

METHODS

This was a questionnaire-based prospective study of 1237 school children aged 9-14 years enrolled from various private and government schools across Delhi in October-December 2020. These children were being followed-up over the previous 2 years (before pandemic) with details of their lifestyle like near/outdoor/reading activities using a questionnaire as a part of another study. The data during the COVID-19 lockdown was collected by telephonic interview. This was compared to similar information collected from this cohort in the pre-Covid period in 2019 when the students had a regular physical school curriculum.

RESULTS

A significant decline was noted in time spent on outdoor activity (from 8.5 hours/week in pre-COVID-19 time to 1.6 hours/week during COVID-19 lockdown; P < 0.001) and doing homework offline (from 15.3 hour/week to 14 hours/week; P < 0.001). A significant increase was noted in screen time spent on digital devices (from 6.2 hours/week to 19.8 hours/week; P<0.001), and watching television (from 12.2 hours/week to 13.4 hours/week; P < 0.001). The rise in the digital on-screen time was significantly more in boys (P < 0.001) and in students from private schools (P < 0.001). The rise in the duration of watching television was significantly more in girls than boys (P < 0.05).

CONCLUSION

COVID-19 lockdown has markedly impacted the lifestyle of school children by significantly decreasing the outdoor activity and increasing the screen time, thereby pre-disposing them to ocular ill-health and myopia. This necessitates the adoption of guidelines for promoting healthy digital habits in children.
