Abstract Objective To conduct a cross-sectional study to investigate the prevalence of overweight, obesity, metabolic syndrome (MetS), pre-diabetes, and diabetes among the nuclear power workers (NPW) in China. Methods We collected information of health check-ups from 1 388 in service workers in a nuclear power station. Overweight, obesity, MetS, pre-diabetes, and diabetes were defined according to guidelines from WHO and the US National Cholesterol Education Program, respectively. Results The age-standardized prevalence of overweight and MetS among NPW (21~59 years old) were 37.50% (95% CI 34.95~40.05%) and 14.02% (95% CI 12.16~15.88%), respectively, both higher than those among adult Chinese population (ACP) (both P < 0.01). The age-standardized prevalence of obesity was 3.27% (95% CI 2.33~4.21%), not significantly different from that among ACP (P > 0.05). The age-standardized prevalence of pre-diabetes and diabetes were 5.14% (95% CI 3.98~6.30%) and 2.70% (95% CI 1.85~3.55%), respectively, both lower than those among ACP (both P < 0.01). Additionally, workers in the 1-9 and 10-19 years groups of working year had 2.94 (95% CI 1.23~7.06) and 3.50 (95% CI 1.37~8.91) fold risk of overweight compared with that in the < 1 year group, respectively. Prevalence of overweight and MetS both increased significantly with increasing working years (Ptrend < 0.01). Conclusion The NPW had relatively high risk of overweight and MetS and its relation with nuclide radiation exposure should be further investigated.
