目的:本研究旨在调查体重指数(BMI)与每周中等强度体力活动频率的关系,饮食行为,以及韩国中学生使用互联网或游戏。
方法:从2023年韩国学生健康检查中收集了23,583名韩国中学生的数据。使用频率对收集的数据进行分析,卡方,和多变量逻辑回归分析。
结果:结果还表明,BMI越高,中等强度体力活动的可能性越大。早餐摄入的可能性随着BMI的增加而降低。然而,使用互联网或游戏的可能性随着BMI的增加而增加。结果显示,28%(23,583人中有6594人)的中学生很少参加中等强度的体育活动,而32%(23,583人中的7553人)每周只参加一次或两次。结果还表明,BMI越高,中等强度体力活动的可能性越高。在那些体重不足的人中,参加中等强度体力活动3~4天的比值比(OR)为0.764(95%置信区间[CI]:0.664~0.880;p<0.001).在那些健康的人中,参与5天以上的OR为1.279(95%CI:1.131-1.446;p<0.001)。在那些超重的人中,参与3-4天和5天以上的OR为1.172(95%CI:1.019-1.348;p=0.026)和1.181(95%CI:1.011-1.380;p=0.036),分别。使用互联网或游戏的可能性随着BMI的增加而增加。在健康和超重的人群中,使用互联网或游戏的OR为0.876(95%CI:0.806-0.952;p=0.002)和0.824(95%CI:0.743-0.913;p<0.001)。分别。然而,早餐摄入的可能性随着BMI的增加而降低。在那些体重不足的人中,经常吃早餐和主要吃早餐的OR为1.299(95%CI:1.114-1.515;p<0.001)和1.236(95%CI:1.045-1.461;p=0.013),分别。在那些健康的人中,总是吃早餐的OR为1.157(95%CI:1.026-1.305;p=0.018)。在那些超重的人中,主要吃早餐的OR为1.215(95%CI:1.030-1.433;p=0.021)。
结论:鉴于此,户外运动可以通过帮助青少年摆脱重复的球类运动并增加他们对体育活动的整体兴趣和参与来增加青少年对体育活动的参与。总的来说,我们的研究结果表明,我们需要摆脱传统的体育教育,发展吸引学生参与中等强度体育活动的项目.
OBJECTIVE: This study aimed to investigate the association of body mass index (BMI) with the weekly frequency of moderate-intensity physical activity, eating behavior, and the use of the Internet or games among Korean middle school students.
METHODS: The data of 23,583 Korean middle school students were collected from the 2023 Korean Student Health Examination. The collected data were analyzed using frequency, chi-square, and multivariate logistic regression analyses.
RESULTS: The results also showed that the higher the BMI, the greater the likelihood of moderate-intensity physical activity. The likelihood of breakfast intake reduced as the BMI increased. However, the likelihood of using the Internet or games increased with an increase in BMI. The results revealed that 28% (6594 of 23,583) of middle school students rarely participate in moderate-intensity physical activity, while 32% (7553 of 23,583) participate only once or twice a week. The results also showed that the higher the BMI, the higher the likelihood of moderate-intensity physical activity. Among those who were underweight, the odds ratio (OR) of 3-4 days of participation in moderate-intensity physical activity was 0.764 (95% confidence interval [CI]: 0.664-0.880; p < 0.001). Among those who were healthy, the OR of more than 5 days of participation was 1.279 (95% CI: 1.131-1.446; p < 0.001). Among those who were overweight, the OR of 3-4 days and more than 5 days of participation was 1.172 (95% CI: 1.019-1.348; p = 0.026) and 1.181 (95% CI: 1.011-1.380; p = 0.036), respectively. The likelihood of the use of the Internet or games increased with an increase in BMI. The OR of the use of the Internet or games was 0.876 (95% CI: 0.806-0.952; p = 0.002) and 0.824 (95% CI: 0.743-0.913; p < 0.001) among those who were healthy and those who were overweight, respectively. However, the likelihood of breakfast intake reduced as the BMI increased. Among those who were underweight, the OR of always eating breakfast and mostly eating breakfast was 1.299 (95% CI: 1.114-1.515; p < 0.001) and 1.236 (95% CI: 1.045-1.461; p = 0.013), respectively. Among those who were healthy, the OR of always eating breakfast was 1.157 (95% CI: 1.026-1.305; p = 0.018). Among those who were overweight, the OR of mostly eating breakfast was 1.215 (95% CI: 1.030-1.433; p = 0.021).
CONCLUSIONS: Given this, outdoor sports may increase adolescents\' participation in physical activities by helping them break away from repetitive ball games and increasing their overall interest and participation in physical activities. Overall, our results suggest the need to move away from traditional physical education and develop engaging physical activity programs that motivate students to participate in moderate-intensity physical activities.
