Rotating shift work significantly increases the risk of metabolic syndrome and systemic inflammation (elevated leukocyte count) in male workers, independent of age and physical activity.
If you work rotating shifts, your body's internal clock is fighting your schedule, raising your risk for metabolic syndrome and inflammation regardless of how much you exercise. Prioritize sleep hygiene and consider 'chronobiotic' strategies like managing light exposure and meal timing to align with your shift, as standard lifestyle advice alone may not fully offset the biological disruption.
The odds ratio for MS in rotating shift workers compared with day workers was 1.51 (95% CI 1.01–2.25), independently of age and physical activity. Increased leucocyte count, a biological marker of systemic inflammation, was associated with rotating shift work.
Why this rating
Large sample size (n=1351) and cross-sectional design with multiple regression controls, but lacks longitudinal causality and potential selection bias.
