The time that adolescents spend using screens is associated with an elevated body mass index (BMI) and decreased physical activity, with gender being an important determinant. There is evidence that an elevated BMI can affect oral health.
To analyze gender differences in physical activity levels and screen time, as well as screen use and BMI, and their associations with DMFT.
Physical activity levels, screen time, and their relationship with the oral health status and BMI were studied in 468 schoolchildren aged 12 to 15 years. To analyze the differences in the numerical data, an analysis of the mean by the Student -test or a one-way analysis of variance followed by the Bonferroni post hoc analysis was used. Moreover, to analyze the differences in the categorical data, the chi-square test was used.
Boys were more active (59.9%) than girls (40.1%) ( < 0.001) in terms of the means of transportation that they used to travel to school. It was observed that boys spent more mean hours playing outdoors than girls (boys: 1.38 ± 0.04 vs. girls: 1.24 ± 0.04; = 0.040). The mean number of hours engaged in sports activities outside school was higher for boys than girls (boys: 2.22 ± 0.06 vs. girls: 1.77 ± 0.73; ≤ 0.001). The mean number of hours spent using electronic devices during the weekend was higher in boys than girls (boys: 2.89 ± 0.08 vs. girls 2.44 ± 0.09; ≤ 0.001). Children with a DMF > 0 had a higher mean BMI than those with a DMFT = 0 (DMFT > 0; 21.95 ±4.80 vs. DMFT = 0; 20.77 ± 3.67; = 0.003).
An increased number of hours spent in front of a computer correlates with a higher BMI. Sex seems to be a determining factor when it comes to engaging in active activities. Caries is more frequent in children with a higher BMI.
青少年使用屏幕的时间与体重指数（BMI）升高及身体活动减少有关，性别是一个重要的决定因素。有证据表明BMI升高会影响口腔健康。
分析身体活动水平和屏幕使用时间的性别差异，以及屏幕使用、BMI及其与龋失补牙面数（DMFT）的关联。
对468名12至15岁的学童的身体活动水平、屏幕使用时间及其与口腔健康状况和BMI的关系进行了研究。为分析数值数据的差异，采用Student检验或单因素方差分析对均值进行分析，随后进行Bonferroni事后分析。此外，为分析分类数据的差异，采用卡方检验。
就上学使用的交通方式而言，男孩比女孩更活跃（59.9%对40.1%）（P<0.001）。观察到男孩在户外玩耍的平均时间比女孩多（男孩：1.38±0.04小时对女孩：1.24±0.04小时；P=0.040）。男孩校外参加体育活动的平均小时数高于女孩（男孩：2.22±0.06小时对女孩：1.77±0.73小时；P≤0.001）。男孩周末使用电子设备的平均小时数高于女孩（男孩：2.89±0.08小时对女孩2.44±0.09小时；P≤0.001）。DMF>0的儿童的平均BMI高于DMFT=0的儿童（DMFT>0；21.95±4.80对DMFT=0；20.77±3.67；P=0.003）。
在电脑前花费的时间增加与较高的BMI相关。在参与积极活动方面，性别似乎是一个决定因素。BMI较高的儿童龋齿更为常见。
