Prevalence of fatty liver and influencing factors among male workers in an automobile manufacturing enterprise

Objective To investigate the prevalence of fatty liver and influencing factors among male workers in an automobile manufacturing enterprise in Guangzhou.

Methods A total of 3 240 male workers from an automobile manufacturing enterprise in Guangzhou who came to a hospital for occupational health examination in 2018 were studied with additional questionnaire, and the correlation between potential affecting factor and occurrence of fatty liver was analyzed.

Results The main occupational hazard factors in the workplaces of this automobile manufacturing enterprise included in benzene series, power frequency electromagnetic field, ultraviolet radiation, nitrogen oxides and dust. The monitoring results showed that the levels of occupational hazards were lower than the national occupational exposure limits, except for the noise (30%, noncompliant). The prevalence of fatty liver in male workers was 14.17%. Multivariate logistic regression analysis showed that the risk of fatty liver increased to 1.092 and 1.957 times with the increment of age and BMI (P < 0.05);marital status, time of service and exposure to occupational hazards were not the influencing factors of fatty liver(P>0.05).

Conclusions The prevalence of fatty liver in male workers of an automobile manufacturer in Guangzhou was low, age and BMI were independent risk factors for fatty liver. Health education for workers should be strengthened.
