title: Effects of Eating Fast and Eating Before Bedtime on the Development of Nonalcoholic Fatty Liver Disease.
abstract: Few studies have evaluated the effects of lifestyle habits, such as eating behaviors, on the development of nonalcoholic fatty liver disease (NAFLD). It is known that NAFLD increases the risk of type 2 diabetes, prediabetes, cardiovascular disease, and chronic kidney disease. Therefore, a retrospective cohort study was conducted to evaluate the effect of eating behaviors and interactions between these behaviors on the development of NAFLD among health insurance beneficiaries without NAFLD. Study subjects were 2254 male and female insurance beneficiaries without NAFLD who had attended specific health checkups during fiscal years 2009 and 2012 among health insurance societies located in Fukuoka and Shizuoka Prefectures (Japan). The incidence of NAFLD was defined as Fatty Liver Index scores ≥60 or visiting medical organizations for fatty liver disease treatment according to claims data. Eating behaviors, including eating speed and eating before bedtime, were evaluated by a self-administered questionnaire. During the study period, 52 (2.3%) subjects progressed to NAFLD. Subjects who ate before bedtime but did not eat fast had a higher risk of NAFLD (adjusted odds ratio [AOR] = 2.15; 95% confidence interval [CI]: 1.03-4.46). Those with both negative eating habits had a significantly higher risk of NAFLD (AOR = 2.48; 95% CI: 1.09-5.63). Subjects who habitually ate before bedtime, and those who ate fast and before bedtime, tended to have an increased risk of NAFLD. Earlier intervention to modify these poor eating behaviors could be useful to prevent NAFLD. (Population Health Management 2016;19:279-283).
