Factors related to adolescents and sleep are understudied. We evaluate the relationship between bedtime technology use (TU), TV in bedroom, weight, and socioeconomic status in seventh graders (N = 3956) enrolled in a school-based wellness intervention. Sleep quantity was dichotomized to insufficient (<8 hours) or sufficient (≥8 hours); high TU before sleep was defined by use "a few nights each week" or "every, or almost every night." Insufficient sleep (38.7%), having TV in bedroom (72.9%), and high TU (83.1%) were commonly reported. The likelihood of sufficient sleep was lower for those with high TU (odds ratio [OR] = 0.529 [0.463-0.605]), obese students (OR = 0.815 [0.700-0.949]), and those with a TV in the bedroom (OR = 0.817 [0.703-0.950]). Also, attending a school with higher percent low socioeconomic status students was also associated with insufficient sleep ( = .026). Interventions to reduce TU may be important for improving sleep quantity, especially for some vulnerable populations.
青少年与睡眠相关的因素研究较少。我们评估了睡眠时使用技术（TU）、卧室里有电视、体重和社会经济地位与参加基于学校的健康干预的 7 年级学生（N = 3956）之间的关系。睡眠量被分为不足（<8 小时）或充足（≥8 小时）；睡前高 TU 定义为每周使用“几天”或“每天，或几乎每天”。报告中常见的情况是睡眠不足（38.7%）、卧室里有电视（72.9%）和睡前高 TU（83.1%）。对于高 TU（比值比[OR] = 0.529 [0.463-0.605]）、肥胖学生（OR = 0.815 [0.700-0.949]）和卧室里有电视的学生（OR = 0.817 [0.703-0.950]），充足睡眠的可能性较低。此外，就读于社会经济地位较低学生比例较高的学校也与睡眠不足有关（ =.026）。减少 TU 的干预措施可能对提高睡眠量很重要，特别是对一些弱势群体。
