Eating behaviors play a crucial role in the development and maintenance of excess weight. The aim of the study was to explore the predictors and changes in eating behaviors among overweight and obese patients.
The sample of the 6-month prospective survey consisted of patients who participated in the inpatient weight loss treatment program in the Lipidological Department of the Szent Imre Hospital (baseline: N=339, 19% men; follow-up: N=175, 16% men). The mean age was 50.2 years (SD=13.47), the mean BMI was 38.6 (SD=7.58) at baseline. Measures: self-reported anthropometric data, Three-Factor Eating Questionnaire Revised 21-Items, CES-D Depression Scale.
According to the results of Multiple Indicators and Multiple Causes analysis, older age predicted greater cognitive restraint (b=0.12, p=0.047). Women were more prone to emotional eating than men (b=0.21, p<0.001). Higher levels of education predicted greater uncontrolled eating (b=0.16, p=0.007) and emotional eating (b=0.12, p=0.039). Depression showed a positive relationship with emotional eating (b=0.19, p=0.001), and mediated the relationship between gender and emotional eating (b=0.04, p=0.009), and BMI and emotional eating (b=0.03, p=0.015). Those whose weight loss was at least 5% showed a greater improvement in the eating behaviors than those whose weight loss was below 5% (cognitive restraint: t(168)=-4.765, p<0.001, uncontrolled eating: t(168)=-2.442, p=0.016, and emotional eating: Z=-2.011, p=0.044).
Results reveal certain determinants of eating behaviors that enhance or obstruct successful long term weight loss and highlight the role of eating behavior changes in weight loss. These mark intervention points for the optimization of results achievable by weight loss treatments.
饮食行为在超重的发生和维持过程中起着关键作用。本研究旨在探讨超重和肥胖患者饮食行为的预测因素及变化情况。
这项为期6个月的前瞻性调查样本包括在圣伊姆雷医院脂质科参加住院减肥治疗项目的患者（基线：N = 339，男性占19%；随访：N = 175，男性占16%）。平均年龄为50.2岁（标准差 = 13.47），基线时平均体重指数为38.6（标准差 = 7.58）。测量指标：自我报告的人体测量数据、21项三因素饮食问卷修订版、CES - D抑郁量表。
根据多指标多原因分析结果，年龄较大预示着更高的认知抑制水平（b = 0.12，p = 0.047）。女性比男性更容易出现情绪化进食（b = 0.21，p < 0.001）。受教育程度较高预示着更高的无节制饮食水平（b = 0.16，p = 0.007）和情绪化进食水平（b = 0.12，p = 0.039）。抑郁与情绪化进食呈正相关（b = 0.19，p = 0.001），并介导了性别与情绪化进食之间的关系（b = 0.04，p = 0.009）以及体重指数与情绪化进食之间的关系（b = 0.03，p = 0.015）。体重减轻至少5%的患者在饮食行为方面的改善比体重减轻低于5%的患者更大（认知抑制：t(168) = -4.765，p < 0.001；无节制饮食：t(168) = -2.442，p = 0.016；情绪化进食：Z = -2.011，p = 0.044）。
研究结果揭示了饮食行为的某些决定因素，这些因素会促进或阻碍长期成功减肥，并突出了饮食行为改变在减肥中的作用。这些为优化减肥治疗可实现的效果指明了干预点。
