Objective

Emotion suppression (ES) is associated with unhealthy coping strategies, such as emotional eating. Physical activity (PA) is a healthy coping strategy that may attenuate the association between emotion suppression and emotional eating (EE). This study evaluated whether: 1) ES is associated with body mass index (BMI) through EE and/or dietary patterns, 2) PA moderates these relationships, and 3) these patterns differ by race/ethnicity and gender.

Methods

Adult participants (N = 1674) of the Family Life, Activity, Sun, Health, and Eating study completed modified versions of the Emotion Regulation, Eating in the Absence of Hunger, and International Physical Activity Questionnaires; a validated dietary assessment; and items on demographics, height, and weight.

Results

Analyses revealed a serial mediation pathway in the full sample where greater ES was associated with higher BMI through greater EE and lower fruit and vegetable (F&V) intake (B = 0.0017, CI 95% [0.0001, 0.0042]) after controlling for age, gender, and education. Hedonic snack food (HSF) intake was not a significant mediator of the ES-BMI association. Greater PA attenuated associations of ES and EE with dietary intake and BMI. The serial pathway remained significant for non-Hispanic White women only in subgroup analyses. EE was a significant mediator among women, and PA effects were largely found among Hispanics and men.

Conclusions

ES was associated with higher BMI through greater EE and lower F&V, but not HSF intake. PA attenuated these associations. Differences in patterns of coping strategies may help to explain disparities in obesity-related health behavior.

情绪抑制、应对策略、饮食模式和 BMI

客观的

情绪抑制 (ES) 与不健康的应对策略有关，例如情绪化饮食。体育活动 (PA) 是一种健康的应对策略，可能会减弱情绪抑制和情绪化进食 (EE) 之间的关联。本研究评估是否：1) ES 通过 EE 和/或饮食模式与体重指数 (BMI) 相关，2) PA 调节这些关系，以及 3) 这些模式因种族/民族和性别而异。

方法

家庭生活、活动、阳光、健康和饮食研究的成年参与者 (N = 1674) 完成了情绪调节、在没有饥饿的情况下进食和国际体育活动问卷的修改版本；经验证的饮食评估；以及有关人口统计、身高和体重的项目。

结果

分析揭示了整个样本中的一系列中介途径，其中在控制年龄、性别后，通过更大的 EE 和更低的水果和蔬菜 (F&V) 摄入量（B = 0.0017, CI 95% [0.0001, 0.0042]），更大的 ES 与更高的 BMI 相关，和教育。享乐休闲食品 (HSF) 的摄入量不是 ES-BMI 关联的重要中介。更大的 PA 减弱了 ES 和 EE 与膳食摄入和 BMI 的关联。仅在亚组分析中，非西班牙裔白人女性的连续途径仍然显着。EE 在女性中是一个重要的中介，而 PA 效应主要在西班牙裔和男性中发现。

结论

ES 通过更高的 EE 和更低的 F&V 与更高的 BMI 相关，但与 HSF 摄入量无关。PA 减弱了这些关联。应对策略模式的差异可能有助于解释肥胖相关健康行为的差异。
