Physical activity (PA), screen time (ST), and sleep are modifiable lifestyle habits for health. The objectives of this study were: a) to examine the association between PA, ST, and both, on sleep patterns; and b) to determine the influence of PA and ST on sleep problems in Chilean girls.
The study involved 196 children (12.2 years). Patterns and sleep problems were assessed using the Spanish version of the Sleep Self-Report, and the PA through the Physical Activity Questionnaire for Adolescents (PAQ-A), both in Castilian. The ST was assessed using several questions about television, game console and computer use.
The ST recommendation (2h a day) was exceeded by 63.2% of the girls. In general, the most active girls (last quartile) that did not exceed the recommendations of ST reported higher sleep quality and total score values compared to those who did not meet both. The logistic regression analysis showed that girls who did not meet both habits were more likely to have sleep quality (odds ratio=17.8, P=.018), and general sleep problems (odds ratio=7.85, P=.025).
Parents need to set limits on sedentary leisure time and encourage more active habits, as sleep is a parameter closely linked to a better health profile in youth.
身体活动（PA）、屏幕时间（ST）和睡眠是可改变的健康生活方式习惯。本研究的目的是：a）研究PA、ST及其二者与睡眠模式之间的关联；b）确定PA和ST对智利女孩睡眠问题的影响。
该研究纳入了196名儿童（12.2岁）。使用西班牙语版的睡眠自我报告评估睡眠模式和睡眠问题，通过青少年身体活动问卷（PAQ-A，西班牙语版）评估身体活动。通过几个关于电视、游戏机和电脑使用的问题评估屏幕时间。
63.2%的女孩超过了屏幕时间建议（每天2小时）。总体而言，未超过屏幕时间建议的最活跃女孩（最后四分位数）与未同时满足这两个条件的女孩相比，睡眠质量和总分值更高。逻辑回归分析表明，未同时满足这两个习惯的女孩更有可能出现睡眠质量问题（优势比=17.8，P=0.018）和一般睡眠问题（优势比=7.85，P=0.025）。
父母需要限制久坐不动的休闲时间，并鼓励养成更积极的习惯，因为睡眠是与青少年更好的健康状况密切相关的一个参数。
