Linking Stress, Emotional Eating & Soldiers

Research Paper Title

Body weight status, perceived stress, and emotional eating among US Army Soldiers: A mediator model.

Background

In civilians, overweight and obesity are associated with emotional eating behaviours such as eating in response to stress, but this association has not been examined in Soldiers, a population with unique stressors.

This cross-sectional study examined the relationship between perceived stress (PS), emotional eating (EE), and outcomes of body mass index (BMI), and failing Army body composition (BC) standards among Soldiers.

Methods

Soldiers (N = 1460, 83% male, 23.5 ± 5.2 years old) completed validated surveys on PS, EE, and adherence with military BC standards.

Conditional process models and mediation models tested gender as a moderator and EE as a mediator of associations between PS and BMI and PS and BC failure, respectively.

Results

Higher PS was associated with more frequent self-reported EE behaviours (p < 0.001), higher BMI (p < 0.001), and BC failure (p < 0.001). BMI significantly increased with frequency of reported EE behaviours (p < 0.001).

Gender was not a statistically significant moderator in the relationship between PS, EE, and, BMI (p = 0.83) or BC failure (p = 0.57). PS appears to affect BMI indirectly through EE behaviours (c’ = 0.03, 95% CI: 0.02, 0.04). PS may affect BC failure directly (c’ = 1.04, 95% CI: 1.01, 1.08) and indirectly (ab = 1.02, 95% CI: 1.01, 1.03) through EE as a mediator.

Conclusions

EE behaviours may mediate the positive association between PS, BMI, and BC failure.

Prospective investigation is warranted to better understand the role of EE in health-related outcomes among Soldiers and populations in high stress professions.
