The aim of this study was to analyze isolated and combined associations of physical inactivity excessive screen time with negative self-rated health, according to sex, among school adolescents.
In this cross-sectional study conducted with 2,517 adolescents in Amazonas State, participants were asked about their self-rated health with the following question: How do you rate your health? Responses were dichotomized into positive (excellent and good) and negative (regular, bad, and terrible). Information on sex, age group, family income, physical activity, and screen time (watching TV, using a computer, or playing video games) was collected through a self-administered questionnaire. Adolescents simultaneously classified as physically inactive (<60 min/day) and having excessive screen time (>2 h/day) were considered to have two risk factors. Data was analyzed using binary logistic regression.
Out of every 10 adolescents, 2 had a negative self-rated health. After adjusting for age and family income, there were no isolated or combined associations between physical inactivity or excessive screen time and negative self-rated health in girls. In boys, negative self-rated health was associated with insufficient levels of physical activity (odds ratio [OR]: 2.39; 95% confidence interval [CI]: 1.03-5.59) and with the accumulation of two risk factors (OR: 1.61; 95%CI 1.10-2.34).
Being insufficiently active and the combination of physical inactivity and excessive screen time become exposure factors to the negative self-rated health of adolescent boys.
本研究旨在分析青少年中，根据性别，将身体活动不足和过度屏幕时间与负面自评健康孤立和联合关联起来。
在这项横断面研究中，对亚马逊州的 2517 名青少年进行了调查，他们被问到以下问题：你如何评价自己的健康状况？回答被分为积极（优秀和良好）和消极（一般、差和差）。通过自我管理问卷收集了性别、年龄组、家庭收入、身体活动和屏幕时间（看电视、使用计算机或玩视频游戏）信息。同时被归类为身体活动不足（每天<60 分钟）和过度屏幕时间（每天>2 小时）的青少年被认为有两个危险因素。使用二元逻辑回归分析数据。
每 10 名青少年中就有 2 名自评健康状况较差。在调整年龄和家庭收入后，女孩中身体活动不足或过度屏幕时间与负面自评健康之间没有孤立或联合关联。在男孩中，负面自评健康与身体活动水平不足（比值比 [OR]：2.39；95%置信区间 [CI]：1.03-5.59）和两个危险因素的积累（OR：1.61；95%CI 1.10-2.34）有关。
身体活动不足以及身体活动不足和过度屏幕时间的结合成为青少年男孩负面自评健康的暴露因素。
