코로나 시기, 일상적 움직임이 감소한 청소년은 어떤 하루를 보내는가

Abstract

Objectives This study investigated Adolescents' tendency to change their daily physical activity(PA) during the corona period, and what differences are seen in the daily lives of adolescents according to the PA level, focusing on the group with decreased PA. Methods Data from 54,848 adolescents who responded to the 17th(2021) Adolescent Health Behavior Survey provided by the Korea Centers for Disease Control and Prevention (KCDC) were used. Daily physical activity(PA) level, time management, mental health, physical health, and academic performance were selected as variables. Descriptive statistics, frequency analysis, crossover analysis, and one-way ANOVA were performed based on the complex sample design Results Korean adolescents experienced generalized anxiety and stress above the standard, and showed a tendency to decrease PA, and there were differences in PA according to gender, school level, and economic level. As a result of analyzing the differences in adolescents' lives according to the PA level, the decreased PA group had the longest sitting time for learning purposes, the least amount of time spent using smartphones during the week. Compared to the group with PA increased group and no change group, general anxiety and stress levels were significantly higher. In addition, more negative results were shown at the level of physical health and physical exercise, and the level of academic achievement was relatively higher. Conclusions Adolescents with decreased PA spent longer sitting for study and had worse mental and physical health. This confirmed that the decrease in PA can have a negative effect on the healthy development of adolescents.
