Abstract
Objective: This study was performed to clarify the relation between fatty liver and lifestyle, nutrients intake, work shifts in employees with high incidence of fatty liver. Methods: Two thousand three hundred and twenty two employees with high incidence of fatty liver in some workplace (group K) and 2,008 examinees of health check-up (group A)were included in this study. We carried out a questionnaire survey and employed logistic regression analysis. Results: The incidence of fatty liver was low in alcohol drinkers and smokers in both groups. The lack of exercise was the risk factor for fatty liver in both groups. In group K, the intake of meals with irregular intervals was also the risk factor. The everyday intake of meat, the short intake of vegetables and the short intake of seaweeds were the risk factors for fatty liver in group A. The incidence of fatty liver was low in the people with everyday intake of soft drinks which contain sugar in group A. On the contrary, the relation between fatty liver and each nutrient was not observed in group K. Conclusion: Wrong eating habits seemed to be the principal risk factor for fatty liver in group K. It is necessary for employers and employees of the workplace of group K to discuss how to reform eating habits.
