Notable weight gain is observed during young adulthood, compared to other adult age groups, yet the relation between eating behavior and body composition at this stage remains poorly understood.
The aim of this cross-sectional study was to assess the association between eating behavior scores (cognitive restraint, uncontrolled eating, and emotional eating), and body composition in a sample of Chilean young adults.
Logistic and linear regression models assessed the independent associations between cognitive restraint, uncontrolled eating, and emotional eating, derived from the Three Factor Eating Questionnaire-R18, and body mass index (BMI), percent body fat by dual-energy X-ray absorptiometry, and central obesity, accounting for demographic covariates, stratified by sex, in a sample of 555 participants of the Santiago Longitudinal Study (mean age 22.6 years [SD 0.4]).
Cognitive restraint was positively associated with obesity, defined by BMI, % body fat, and central obesity. Emotional eating was related to obesity, defined by % body fat and central obesity in men and women and to obesity, defined by BMI, in women. Cognitive restraint was related to BMI in men and % body fat in women. Uncontrolled eating was not associated with adiposity in men or women.
In Chilean young adults, cognitive restraint and emotional eating scores were associated with higher BMI, elevated percent body fat, and greater central obesity.
与其他成年年龄段相比，年轻人在成年早期会明显增重，但这一阶段的饮食行为与身体成分之间的关系仍知之甚少。
本横断面研究旨在评估智利年轻成年人样本中饮食行为评分（认知约束、失控性进食和情绪性进食）与身体成分之间的关系。
采用逻辑回归和线性回归模型，评估了源自三因素饮食问卷-R18 的认知约束、失控性进食和情绪性进食与身体质量指数（BMI）、双能 X 射线吸收法测定的体脂肪百分比和中心性肥胖之间的独立关联，考虑了人口统计学协变量，并按性别分层，样本来自圣地亚哥纵向研究的 555 名参与者（平均年龄 22.6 岁[SD 0.4]）。
认知约束与肥胖（BMI、体脂肪百分比和中心性肥胖定义）呈正相关。情绪性进食与男性和女性的肥胖（体脂肪百分比和中心性肥胖定义）和女性的肥胖（BMI 定义）相关，而与男性的肥胖（BMI 定义）和女性的体脂肪百分比相关。认知约束与男性的 BMI 和女性的体脂肪百分比相关。失控性进食与男性或女性的肥胖无关。
在智利年轻成年人中，认知约束和情绪性进食评分与较高的 BMI、体脂肪百分比升高和中心性肥胖有关。
