Insufficient sleep may lead to adverse health effects, influencing body weight. This study quantified the prevalence of short sleep and the association between sleep duration and overweight in a sample of suburban students. Cross-sectional study was conducted in 2004, involving 529 students from Bay High School, Bay Village, OH, USA, using self-administered questionnaires assessing lifestyle and sleep behaviors. Students with a body mass index Z Score >85th percentile for sex and age were deemed overweight. Ninety percent of students reported average sleep time less than 8 h on school nights, with 19% reported less than 6 h of sleep per night. Twenty percent of the sample were overweight. Overweight was significantly associated with the male gender, increased caffeine consumption, and short sleep duration. Compared with students sleeping >8 h, the age and gender-adjusted odds ratio of overweight was 8.53 (95% CI: 2.26, 32.14) for those with <5 h sleep (P = 0.0036); 2.79 (1.03, 7.55) for those with 5-6 h sleep; 2.81 (1.14, 6.91) for those with 6-7 h sleep; and 1.29 (0.52, 3.26) for those with 7-8 h sleep. Short sleep duration was common and associated with overweight with evidence of a "dose-response" relationship. These results confirm a high prevalence of short sleep among suburban high school students and provide additional support suggesting significant association between short sleeping hours and overweight.
睡眠不足可能会对健康产生不利影响，进而影响体重。本研究对郊区学生样本中短睡眠的患病率以及睡眠时间与超重之间的关联进行了量化。2004年进行了一项横断面研究，涉及来自美国俄亥俄州贝村贝高中的529名学生，使用自行填写的问卷评估生活方式和睡眠行为。体重指数Z评分高于性别和年龄第85百分位的学生被视为超重。90%的学生报告上学日晚上平均睡眠时间少于8小时，19%的学生报告每晚睡眠时间少于6小时。20%的样本超重。超重与男性性别、咖啡因摄入量增加和睡眠时间短显著相关。与睡眠时间超过8小时的学生相比，睡眠时间不足5小时的学生经年龄和性别调整后的超重比值比为8.53（95%CI：2.26，32.14）（P = 0.0036）；睡眠时间为5 - 6小时的学生为2.79（1.03，7.55）；睡眠时间为6 - 7小时的学生为2.81（1.14，6.91）；睡眠时间为7 - 8小时的学生为1.29（0.52，3.26）。睡眠时间短很常见，且与超重相关，存在“剂量 - 反应”关系的证据。这些结果证实了郊区高中生中短睡眠的高患病率，并进一步支持了睡眠时间短与超重之间存在显著关联的观点。
