Adherence
Alternating shift work is an independent risk factor for significant weight gain (defined as ≥5%, 7.5%, or 10% increase in BMI) in male Japanese workers compared to regular day workers.
If you work alternating shifts, be aware that your schedule likely disrupts your eating patterns, leading to more frequent meals (often 4/day) and potentially higher intake of fried foods. To prevent weight gain, focus on controlling meal timing and food quality rather than assuming weight gain is inevitable due to your schedule.
Our study revealed that alternating shift work was an independent risk factor for weight gain in male Japanese workers.
Why this rating
Longitudinal cohort study (14 years) with large sample size (n=7,254) and rigorous statistical adjustment for confounders, though observational design prevents causal proof of mechanism.
