Association of occupational factors,dietary factors and metabolic syndrome in male rolling mill workers / 中国职业医学

ABSTRACT

OBJECTIVE: To explore the relationship of exposure to occupational hazards,labor intensity,dietary factors and the metabolic syndrome( MS) in male rolling mill workers. METHODS: A total of 1 105 male workers in a rolling mill were studied as research objects by judgment sampling method. The basic information of the subjects was collected by questionnaire survey and health examination. The prevalence of MS was analyzed according to different individual characteristics of workers. Multi-factor logistic regression analysis was conducted for analysis of the affecting factors of MS.RESULTS: The prevalence of MS in the subjects was 32. 5%( 359/1 105). The prevalence of MS in workers exposed to occupational hazards was higher than that in the control group( 33. 5% vs 20. 2%,P < 0. 05). The prevalence of MS increased with age( P < 0. 05),and decreased with the increase of labor intensity and family per capita monthly income( P < 0. 05). The prevalence of MS in smokers was higher than that in non-smokers( P < 0. 017),and the prevalence of MS in workers with animal dietary was higher than those with balanced dietary and with traditional dietary( P < 0. 017).The multivariate logistic regression analysis showed that after the adjustment of confounding factors such as age,seniority,family per capita monthly income,smoking and drinking,MS risk in a single factor of carbon monoxide exposure group,high temperature combined with carbon monoxide exposure group and high temperature combined with noise exposure group were higher than that of the control group without exposure to occupational hazards respectively( P < 0. 05),and the ratio of the 95% confidence interval were 2. 246( 1. 097-4. 597),2. 581( 1. 308-5. 094) and 2. 435( 1. 281-4. 627). The risk of MS in workers with animal dietary was higher than that with traditional dietary( P < 0. 01),the odds ratio and 95%confidence interval was 1. 497( 1. 106-2. 025). The grade of MS was 24. 6% lower than the original labor intensity with each increasing grade of risk( P < 0. 05). CONCLUSION: The animal dietary,increased labor intensity,exposure to carbon monoxide,high temperature combined with carbon monoxide and high temperature combined with noise can all increase the risk of MS.
