BACKGROUND & AIMS: Previous studies have shown improvements in eating behaviors following a Health-At-Every-Size approach (HAES). However, to our knowledge, no study has yet investigated how a HAES intervention could influence dietary intakes and eating patterns in overweight women. Therefore, objectives of this study were to determine changes in dietary intakes and eating patterns in premenopausal overweight women in response to a HAES intervention compared to a social support intervention and a control group, and then to determine whether changes in eating behaviors were associated with changes in dietary intakes and eating patterns in response to the HAES intervention.
Women completed a 3-day food record and the Three-Factor Eating Questionnaire was used to assess eating behaviors.
Energy intake (main effect of time; p = 0.045) and snack frequency (main effect of time; p = 0.0004) decreased similarly over time in the three groups whereas proportion of energy intake from breakfast (main effect of time; p = 0.03) increased over time. Within HAES group, decreases in hunger and external hunger were associated with a decrease in total daily energy intake (r = 0.50, p = 0.0009 and r = 0.50, p = 0.0007, respectively).
HAES intervention has no specific impact on eating patterns. However, a decrease in hunger, which characterizes women who respond well to HAES, is associated with a decrease in overall energy intake. Clinical trial registration number (www.clinicaltrials.gov): NCT01240499.
先前的研究表明，健康体型（HAES）方法可以改善饮食行为。然而，据我们所知，尚无研究调查 HAES 干预如何影响超重女性的饮食摄入和饮食模式。因此，本研究的目的是确定与社会支持干预和对照组相比，HAES 干预对绝经前超重女性的饮食摄入和饮食模式的变化，然后确定饮食行为的变化是否与 HAES 干预对饮食摄入和饮食模式的变化相关。
女性完成了 3 天的食物记录，使用三因素饮食问卷评估饮食行为。
三组的能量摄入（时间的主要效应；p = 0.045）和零食频率（时间的主要效应；p = 0.0004）随时间相似地减少，而早餐能量摄入比例（时间的主要效应；p = 0.03）随时间增加。在 HAES 组中，饥饿感和外在饥饿感的减少与总日能量摄入的减少相关（r = 0.50，p = 0.0009 和 r = 0.50，p = 0.0007，分别）。
HAES 干预对饮食模式没有特定影响。然而，对 HAES 反应良好的女性的饥饿感下降与总能量摄入的减少相关。临床试验注册号（www.clinicaltrials.gov）：NCT01240499。
