To determine if self-reported sleep duration was associated with weight-control behaviors among US high school students.
National Youth Risk Behavior Survey.
United States, 2007.
US high school students (N = 12,087).
Students were asked if they had engaged in several weight-control behaviors during the 30 days before the survey to lose or maintain weight. Self-reported sleep duration categories included very short (≤ 5 h), short (6 or 7 h), referent moderate (8 or 9 h), and long (≥ 10 h). Sex-specific logistic regression analyses with race/ethnicity, grade, and body mass index category as covariates were conducted using SUDAAN to account for complex study design.
Approximately half the students reported short sleep duration (51.8% of males and 54.3% of females), whereas very short sleep durations were reported by another 14.8% of males and 16.9% of females. Among males, very short sleepers were significantly (P < 0.05) more likely than moderate sleepers to report dieting (36.3% versus 26.1%), fasting (14.2% versus 4.3%), and purging (4.3% versus 1.1%) to lose or maintain weight during the 30 days before the survey. Among females, the respective very short, short, and moderate sleepers varied (P < 0.05) in dieting (59.9%, 55.0%, and 47.5% respectively), fasting (28.3%, 15.2%, and 10.3%, respectively), and taking diet pills (13.3%, 6.8%, and 4.3%, respectively). Prevalence of purging was significantly higher only for very short sleepers (12.3%, 6.0%, and 3.9%, respectively).
Self-reported short sleep duration was associated with dieting and three unhealthy weight-control behaviors in this population. If our findings are confirmed, intervention studies should be conducted to examine the effect of educational interventions.
确定美国高中生自我报告的睡眠时间与体重控制行为之间的关系。
全国青年风险行为调查。
美国，2007 年。
美国高中生（N=12087）。
学生被问及在调查前 30 天内是否采取了几种体重控制行为来减肥或保持体重。自我报告的睡眠时间类别包括非常短（≤5 小时）、短（6 或 7 小时）、参考中等（8 或 9 小时）和长（≥10 小时）。使用 SUDAAN 进行了性别特异性的逻辑回归分析，将种族/民族、年级和体重指数类别作为协变量，以考虑复杂的研究设计。
大约一半的学生报告睡眠时间短（男生 51.8%，女生 54.3%），而另外 14.8%的男生和 16.9%的女生报告睡眠时间非常短。在男生中，非常短的睡眠时间者比中等睡眠时间者更有可能报告节食（36.3%比 26.1%）、禁食（14.2%比 4.3%）和催吐（4.3%比 1.1%）在调查前 30 天减肥或保持体重。在女生中，不同的非常短、短和中等睡眠时间者在节食（分别为 59.9%、55.0%和 47.5%）、禁食（分别为 28.3%、15.2%和 10.3%）和服用减肥药（分别为 13.3%、6.8%和 4.3%）方面存在差异（P<0.05）。仅非常短睡眠时间者的催吐患病率显著较高（分别为 12.3%、6.0%和 3.9%）。
在该人群中，自我报告的短睡眠时间与节食和三种不健康的体重控制行为有关。如果我们的发现得到证实，应该进行干预研究来检验教育干预的效果。
