月经周期波动对限制性饮食者进食量的影响

Menstrual Cycle Fluctuations as an Influence on Food Intake among Restrained Eaters

摘要: 目的：本研究旨在探讨限制性饮食者在月经周期不同阶段的食物摄入量的变化。方法：对参与实验的113名重庆某高校女生(限制性饮食者60名和非限制性饮食者53名)，分别在月经周期的卵泡期和黄体期两个阶段进行20分钟的问卷填写实验，测量每一名被试在问卷填写过程中的食物摄入量，之后对实验所得数据采用2 × 2重复测量方差分析。结果：1) 月经阶段的主效应结果显著，被试在黄体期的食物摄入量高于在卵泡期的食物摄入量；2) 组别主效应结果不显著；3) 月经阶段与组别的交互作用结果显著。限制性饮食者在卵泡期的进食量小于非限制性饮食者的进食量，而在黄体期阶段，限制性饮食者的进食量大于非限制性饮食者的进食量。结论：限制性饮食者在月经阶段的卵泡期更容易控制饮食，而在黄体期阶段则会倾向于过度进食。

Abstract: Objective: This study aims to investigate the influence of menstrual cycle fluctuations on food intake among restrained eaters. Methods: A total of 113 female students (60 with restrictive diet and 53 with non-restrictive diet) in a university in Chongqing participated in the experiment. A 20-minute questionnaire filling experiment was conducted in the follicular phase and luteal phase of the menstrual cycle, respectively. Food intake of each subject was measured during the filling of the questionnaire, and then the experimental data were analyzed by 2 × 2 repeated measurement variance. Results: 1) The main effect of menstrual phase was significant, and the snack consumption of the participants in the luteal phase was higher than that in the follicular stage; 2) the main effect of group was not significant; 3) The interaction between the phase of the menstrual cycle and group was significant. In the follicular phase, restrained eaters consumed less snacks than non-restrained eaters; while in the luteal phase, restrained eaters consumed more snacks than the non-restrained eaters. Conclusion: Restrained eaters are more likely to control their diet during the follicular phase of menstruation and tend to overeat during the luteal phase of menstruation.
