STUDY OBJECTIVE
To investigate whether the relationship between short sleep duration and subsequent body weight gain is influenced by disinhibited eating behavior.
DESIGN
Six-year longitudinal study.
SETTING
Community setting.
PARTICIPANTS
Two hundred seventy-six adults aged 21 to 64 years from the Quebec Family Study.
MEASUREMENTS AND RESULTS
Body composition measurements, self-reported sleep duration, and disinhibition eating behavior trait (Three-Factor Eating Questionnaire) were determined at both baseline and after 6 years. For each sleep-duration group (short- [≤6 h] average, [7-8 h], and long- [≥9 h] duration sleepers), differences in weight gain and waist circumference were tested by comparing the lowest (score ≤ 3) versus the highest (score ≥ 6) disinhibition eating behavior tertiles using analysis of covariance, with adjustment for potential confounding factors. Individuals having both short sleep duration and high disinhibition eating behavior were more likely to gain weight and increase their abdominal circumference over time (P<0.05); however, short-duration sleepers having a low disinhibition eating behavior trait were not more likely to increase their adiposity indicators than were average-duration sleepers. Over the 6-year follow-up period, the incidence of overweight/obesity for short-duration sleepers with a high disinhibition eating behavior trait was 2.5 times more frequent than for short-duration sleepers with a low disinhibition eating behavior trait. Energy intake was significantly higher in short-duration sleepers with a high disinhibition eating behavior trait (P<0.05 versus all other groups).
CONCLUSIONS
We observed that having a high disinhibition eating behavior trait significantly increased the risk of overeating and gaining weight in adults characterized by short sleep duration. This observation is novel and might explain the interindividual differences in weight gain associated with short sleep duration.
研究目的
探究睡眠时长较短与随后体重增加之间的关系是否受进食抑制行为的影响。
研究设计
六年纵向研究。
研究地点
社区环境。
研究对象
魁北克家庭研究中的 276 名年龄在 21 至 64 岁的成年人。
测量和结果
在基线和 6 年后，通过人体成分测量、自我报告的睡眠时长和进食抑制行为特质（三因素饮食问卷）进行测量。对于每个睡眠时长组（短[≤6 h]、[7-8 h]和长[≥9 h]睡眠时间），通过比较最低（得分≤3）和最高（得分≥6）的进食抑制行为三分位数，采用协方差分析比较体重增加和腰围的差异，调整潜在混杂因素。同时存在睡眠时长较短和进食抑制行为较高的个体随着时间的推移更有可能增加体重和增加腰围（P<0.05）；然而，睡眠时长较短且进食抑制行为特质较低的个体比平均睡眠时长的个体增加肥胖指标的可能性更小。在 6 年的随访期间，具有高进食抑制行为特质的短睡眠者发生超重/肥胖的几率是具有低进食抑制行为特质的短睡眠者的 2.5 倍。具有高进食抑制行为特质的短睡眠者的能量摄入明显更高（P<0.05 与所有其他组相比）。
结论
我们发现，具有高进食抑制行为特质的成年人睡眠时长较短，这显著增加了暴饮暴食和体重增加的风险。这一观察结果是新颖的，可能解释了与短睡眠时长相关的个体间体重增加的差异。
