Association Between Health Behaviors and Mental Health Among Airline Pilots

Abstract

Background

Lifestyle behaviors including physical activity, sleep, nutrition, smoking, and alcohol consumption are independently associated with health, yet the relationship between these behaviors and mental health has not been explored among airline pilots. The aim of this study was to measure the association between health behaviors and mental health.

Methods

A cross-sectional study was conducted among 502 airline pilots. The primary outcome measure was the mental component score (MCS), derived from the Short Form Health Survey 12v2. We collected information regarding age, sex, ethnicity, height, body mass, alcohol consumption, tobacco smoking status, moderate-to-vigorous physical activity (MVPA), fruit and vegetable intake, and sleep duration.

Results

After controlling for demographic and anthropometric parameters, MVPA, fruit and vegetable intake, and sleep duration were positively correlated with MCS (p ≤ 0.001), and alcohol consumption and tobacco smoking were negatively correlated with MCS (p ≤ 0.001). Multiple linear regression analyses revealed alcohol consumption was the strongest predictor of MCS (β = −0.308, p ≤ 0.001), followed by smoking (β = −0.236, p ≤ 0.001), MVPA (β = 0.233, p ≤ 0.001), sleep (β = 0.148, p ≤ 0.001), and fruit and vegetable intake (β = 0.097, p = 0.003).

Conclusion

The results suggest that greater physical activity, sleep duration, and fruit and vegetable intake are associated with better mental health. Meanwhile, excessive alcohol consumption and tobacco smoking undermine mental health status.
