To examine the association between sleep duration and asthma among Florida high school students and whether body mass index (BMI) modifies this association.
This cross-sectional analysis included 16,728 participants in the Florida Youth Risk Behavior Survey (2009-2013). Using logistic regression, we examined the association between sleep duration and asthma, and, after controlling for potential confounders, analyzed the interaction between sleep duration and BMI.
Sleeping for less than 7 h or more than 8 h on school night was associated with increased odds of current asthma. Compared with 7-8 h of sleep per night, sleeping for <7 h had an OR of 1.22 (95% CI 1.07, 1.40), while sleeping for ≥9 h had and OR of 1.31 (1.06, 1.63). When stratified by body mass index (BMI), these associations were significant only in overweight adolescents, with those sleeping for <7 or ≥9 h having approximately twice the odds of having current asthma (OR = 1.75 (1.45, 2.11) and OR = 2.00 (1.32, 3.02) respectively), compared with normal weight adolescents who slept for 7-8 h per night.
The association between sleep duration and asthma in adolescents is modified by BMI. Short and long sleep durations are associated with asthma in overweight adolescents while no significant association is seen in those with normal BMI.
研究佛罗里达州高中生睡眠时间与哮喘之间的关联，以及体重指数（BMI）是否会改变这种关联。
这项横断面分析纳入了佛罗里达青少年风险行为调查（2009 - 2013年）中的16728名参与者。我们使用逻辑回归分析睡眠时间与哮喘之间的关联，并在控制潜在混杂因素后，分析睡眠时间与BMI之间的相互作用。
上学日晚上睡眠时间少于7小时或超过8小时与当前哮喘的患病几率增加相关。与每晚睡7 - 8小时相比，睡眠时间<7小时的OR为1.22（95%CI 1.07, 1.40），而睡眠时间≥9小时的OR为1.31（1.06, 1.63）。按体重指数（BMI）分层时，这些关联仅在超重青少年中显著，与每晚睡7 - 8小时的正常体重青少年相比，睡眠时间<7小时或≥9小时的青少年患当前哮喘的几率约为两倍（OR分别为1.75（1.45, 2.11）和2.00（1.32, 3.02））。
青少年睡眠时间与哮喘之间的关联受BMI影响。睡眠时间过短和过长与超重青少年的哮喘相关，而在BMI正常的青少年中未观察到显著关联。
