To examine the associations between eating behavior traits and weight loss according to sleep quality and duration in adults enrolled in common weight-loss interventions.
Participants included overweight and obese men and women (n=150) (mean±s.d. age, 38.8±8.6 years; mean±s.d. body mass index (BMI), 33.3±3.5 kg m(-2)) who were subjected to a dietary intervention over a period of 12-16 weeks. Anthropometric measurements, eating behavior traits (Three-Factor Eating Questionnaire), sleep quality (total Pittsburgh Sleep Quality Index (PSQI) score) and sleep duration (hours per night, self-reported from the PSQI) were assessed at both baseline and post intervention. Linear regression analysis was used to quantify the relationships between eating behavior traits and changes in anthropometric markers for all subjects and by sleep categories (short sleep: <7 h per night vs recommended sleep: ⩾7 h per night; poor sleep quality: ⩾5 PSQI score vs good sleep quality: <5 PSQI score). We adjusted for age, sex and baseline BMI in analyses.
Baseline eating behavior traits were modest predictors of weight-loss success, but they were all significantly associated with their changes over the weight-loss intervention (P<0.01). The diet intervention induced significant changes in eating behavior traits and even more for those having a non-favorable eating behavior profile at baseline. We observed that changes in flexible control and strategic dieting behavior were constantly negatively associated with changes in body weight and fat mass (P<0.05) for recommended duration sleepers. The change in situational susceptibility to disinhibition was positively associated with the change in fat mass and body weight for those having healthy sleeping habits (P<0.05). For poor quality sleepers, the change in avoidance of fattening foods was negatively associated with changes in adiposity (P<0.05).
Eating behavior traits and sleep may act together to influence the outcome of weight-loss programs.
在参加常见减肥干预措施的成年人中,根据睡眠质量和时长来研究饮食行为特征与体重减轻之间的关联。
参与者包括超重和肥胖的男性与女性(n = 150)(平均±标准差年龄,38.8±8.6岁;平均±标准差体重指数(BMI),33.3±3.5 kg/m²),他们接受了为期12 - 16周的饮食干预。在基线和干预后均评估人体测量指标、饮食行为特征(三因素饮食问卷)、睡眠质量(匹兹堡睡眠质量指数(PSQI)总分)和睡眠时间(每晚小时数,通过PSQI自我报告)。采用线性回归分析来量化所有受试者以及按睡眠类别(短睡眠:每晚<7小时与推荐睡眠:每晚⩾7小时;睡眠质量差:PSQI得分⩾5分与睡眠质量好:PSQI得分<5分)划分的饮食行为特征与人体测量指标变化之间的关系。在分析中我们对年龄、性别和基线BMI进行了校正。
基线饮食行为特征是减肥成功的适度预测指标,但它们均与减肥干预期间的变化显著相关(P<0.01)。饮食干预引起了饮食行为特征的显著变化,对于基线时饮食行为特征不佳的人变化更大。我们观察到,对于推荐睡眠时间的人,灵活控制和策略性节食行为的变化与体重和体脂的变化持续呈负相关(P<0.05)。对于有健康睡眠习惯的人,情境性去抑制易感性的变化与体脂和体重的变化呈正相关(P<0.05)。对于睡眠质量差的人而言,避免食用易胖食物的变化与肥胖程度的变化呈负相关(P<0.05)。
饮食行为特征和睡眠可能共同作用以影响减肥计划的结果。
