BACKGROUND: The present study aims to analyze variables related to overweight/obesity in an Italian workers population, with particular attention to shift work.
METHODS: This cross-sectional study analyzed the data retrieved from the “Aspects of daily life” survey, carried out by ISTAT in 2012.
RESULTS: 16,725 participants (aged 18-64) met inclusion criteria; 44.28% of workers were overweight or obese (56.36% of males vs 27.24% of females, p<0.001). Ac-cording to the logistic regression analysis, female (OR 0.28, 95% CI 0.26-0.31) and highly educated workers (OR 0.70, 95% CI 0.65-0.75) showed less risk of being overweight/obese compared to male and less educated workers. Aging was associated with an elevated risk (those aged >64 yrs compared to younger colleagues: OR 4.02, 95% CI 2.91-5.58) as well as artisans compared to employees (OR 1.11, 95% CI 1.01-1.23) and shift-work compared to daytime-work (OR 1.14, 95% CI 1.03-1.26).
DISCUSSION: Our analysis in the Italian context is consistent with the existing knowl-edge, suggesting that overweight is significantly associated with shift work, even when controlling for important covariates, such as education, age, gender, civil status, BMI category.
