Objectives: To investigate the prevalence of obesity among different types of employment status in the Italian working population, and to examine associated risk factors. Material and Methods: Cross-sectional survey of 36 814 people that declared to have been occupied with the same type of contract for at least 5 years was analyzed. Multivariable logistic regression models were built considering workers’ sex, age, education, family body mass index (BMI) category, leisure time and occupational physical activity, weight control habits, smoking habit, use of drugs, number of working hours per week, and type of working contract. Results: After adjusting for covariates, the importance of temporary-employment was confirmed by multivariate analysis, with odds ratio (OR) = 1.32 for obesity (95% confidence interval (CI): 1.07–1.63) with respect to employed persons; the association was even more important in workers occupied for more than 40 h/week (OR = 1.69, 95% CI: 1.07–2.66); moreover, shiftwork was confirmed as a risk factor for obesity in workers (OR = 1.06, 95% CI: 0.94–1.2). Dealing with different occupational group, some categories were associated with obesity; in particular, this phenomenon involved people employed in agriculture (OR = 1.44, 95% CI: 1.22–1.7), transportation (OR = 1.53, 95% CI: 1.26–1.85), and public administration (OR = 1.31, 95% CI: 1.1–1.55). Conclusions: Our analysis suggest that obesity is strongly correlated with temporary employment. Maybe the way out this pathway to obesity in the future might be working better, choosing organizational flexibility rather than fixed term. Int J Occup Med Environ Health 2016;29(6):903–914
