The number of weight loss attempts may be associated with higher weight status and unfavorable health behaviors as well as dysfunctional eating behaviors. We aimed to study eating behavior tendencies, i.e., cognitive restraint, uncontrolled eating and emotional eating among a sample of Finnish adults who had engaged in a different number of attempts to lose weight during their lifetime.
Data were collected through a web-based survey. Participants completed a background questionnaire (including questions on weight, height, number of attempts to lose weight) and the Three-Factor Eating Questionnaire (TFEQ-R18). Out of 1985 individuals, 1679 with complete data were included in the study. The TFEQ-R18 was tested for its reliability and fit to our study population using Cronbach's alpha and Confirmatory Factor Analysis (CFA).
Subscales of the TFEQ-R18 had acceptable reliability except for that of 'cognitive restraint', which reached acceptable reliability when three items were deleted (items 15, 16, 18). The revised version of the questionnaire was designated as the TFEQ-R15, which showed good fit based on CFA fit indices. Participants who had attempted to lose weight during their lifetime (n = 1229), especially those with ≥3 weight loss attempts (n = 499), had greater cognitive restraint, uncontrolled eating, emotional eating, and higher body mass index (BMI) than those with no previous weight loss attempts (n = 132).
Our findings suggest that eating behavior tendencies, i.e., decreasing tendencies of uncontrolled and emotional eating should receive more emphasis to support successful weight management.
减肥尝试的次数可能与较高的体重状态和不良的健康行为以及功能失调的饮食行为有关。我们旨在研究芬兰成年人的饮食行为倾向，即在一生中进行了不同次数减肥尝试的人群，研究他们的认知控制、失控性进食和情绪性进食。
通过网络调查收集数据。参与者完成了一份背景问卷（包括体重、身高、减肥尝试次数等问题）和三因素饮食问卷（TFEQ-R18）。在 1985 名参与者中，有 1679 名有完整数据的人被纳入研究。使用 Cronbach's alpha 和验证性因素分析（CFA）对 TFEQ-R18 的可靠性和适用于我们研究人群的情况进行了测试。
除了“认知控制”外，TFEQ-R18 的子量表具有可接受的可靠性，当删除三个项目（项目 15、16、18）时，其达到了可接受的可靠性。修订后的问卷被命名为 TFEQ-R15，根据 CFA 拟合指数，它具有良好的拟合度。一生中曾尝试减肥的参与者（n=1229），尤其是尝试减肥≥3 次的参与者（n=499），与从未尝试减肥的参与者（n=132）相比，他们的认知控制、失控性进食、情绪性进食和体重指数（BMI）更高。
我们的研究结果表明，饮食行为倾向，即减少失控性和情绪性进食的倾向，应更加重视，以支持成功的体重管理。
