OBJECTIVETo investigate the relationship between ideal cardiovascular behaviors/factors and nonalcoholic fatty liver disease.

METHODSIn our study, 54 303 workers who had participated in the 2006-2007 Kailuan health examination with complete data and without history of drinking, myocardial infarction, stroke or cancer, were recruited. All workers were under observation and their prevalence of nonalcoholic fatty liver disease recorded. According to the American Heart Association definition of ideal cardiovascular health behaviors and factors, multiple logistic regression method was used to calculate the OR and 95% CI for baseline behaviors and factors.

RESULTSThe prevalence of nonalcoholic fatty liver disease according to 0-1, 2, 3, 4, 5-7 ideal cardiovascular health behaviors/factors were 62.6% , 48.9% , 33.3% , 16.1% and 7.5% , respectively. Results from the logistic model showed that after adjustment for age, gender, income, education level and other confounders, the ideal cardiovascular health behaviors/factors were associated with nonalcoholic fatty liver disease and the ORs (95% CI) were reduced gradually with the increase of ideal cardiovascular health behaviors/factors, which were 1,0.61(0.56-0.66), 0.37(0.34-0.40), 0.17(0.15-0.18) and 0.08 (0.07-0.09), respectively, in the 2, 3, 4, 5-7 ideal behaviors/factors groups.

CONCLUSIONIdeal cardiovascular health behaviors and factors were associated with nonalcoholic fatty liver disease.
