To examine associations between insufficient sleep (<8h on average school nights) and health-risk behaviors.
2007 national Youth Risk Behavior Survey data of U.S. high school students (n=12,154) were analyzed. Associations were examined on weighted data using multivariate logistic regression.
Insufficient sleep on an average school night was reported by 68.9% of students. Insufficient sleep was associated with higher odds of current use of cigarettes (age-adjusted odds ratio [AOR], 1.67; 95% confidence interval [CI], 1.45-1.93), marijuana (AOR, 1.52; 95% CI, 1.31-1.76), and alcohol (AOR, 1.64; 95% CI, 1.46-1.84); current sexual activity (AOR, 1.41; 95% CI, 1.25-1.59); seriously considered attempting suicide (AOR, 1.86; 95% CI, 1.60-2.16); feeling sad or hopeless (AOR, 1.62; 95% CI, 1.43-1.84); physical fighting (AOR, 1.40; 95% CI, 1.24-1.60), not being physically active at least 60min ≥ 5days in the past 7days (AOR, 1.16; 95% CI, 1.04-1.29), using the computer ≥3h/day (AOR, 1.58; 95% CI, 1.38-1.80), and drinking soda/pop > 1time/day (AOR, 1.14; 95% CI, 1.03-1.28).
Two-thirds of adolescent students reported insufficient sleep, which was associated with many health-risk behaviors. Greater awareness of the impact of sleep insufficiency is vital.
研究平均每晚睡眠时间不足 8 小时与健康风险行为之间的关联。
对美国高中生 2007 年全国青少年风险行为调查的数据（n=12154）进行分析。采用多变量逻辑回归对加权数据进行关联分析。
68.9%的学生报告平均每晚睡眠时间不足。睡眠时间不足与当前使用香烟（年龄调整后的优势比[OR]，1.67；95%置信区间[CI]，1.45-1.93）、大麻（OR，1.52；95%CI，1.31-1.76）和酒精（OR，1.64；95%CI，1.46-1.84）的几率较高有关；当前性行为（OR，1.41；95%CI，1.25-1.59）；曾认真考虑自杀（OR，1.86；95%CI，1.60-2.16）；感到悲伤或绝望（OR，1.62；95%CI，1.43-1.84）；身体打架（OR，1.40；95%CI，1.24-1.60），在过去 7 天内至少 60 分钟不进行 5 天以上的体育活动（OR，1.16；95%CI，1.04-1.29），每天使用计算机≥3 小时（OR，1.58；95%CI，1.38-1.80），以及每天饮用苏打水/可乐>1 次（OR，1.14；95%CI，1.03-1.28）。
三分之二的青少年学生报告睡眠时间不足，这与许多健康风险行为有关。提高对睡眠不足影响的认识至关重要。
