Objectives To explore any gender-related differences in prevalence of and condition-associated factors related to non-alcoholic fatty liver disease (NAFLD) amongst police population in Taipei, Taiwan.
Methods We studied a total of 1016 healthy adults with police work (972 males and 44 females) voluntarily admitted to physical check-up between January 2006 and December 2006. Blood samples and ultrasound-proved fatty liver sonography results were collected.
Results The prevalence of NAFLD for this subpopulation was found to be 52.2%, the prevalence revealing a statistically significant decrease with increasing population age (p<0.001). Males exhibited a greater prevalence of NAFLD than did females (53.6% vs 20.5%, p<0.0001). Using multiple logistic regression analysis, in addition to male gender, an older age, higher BMI, higher ALT, presence of hyperuricaemia, hypercholesterolemia, and hypertriglyceridaemia were the significant factors associated with NAFLD. Gender-related differences as regards associated factors were also revealed. For males, hyperuricaemia (OR=1.35, 95% CI: 1.07 to 1.86), higher ALT (OR=2.31, 95% CI: 1.50 to 3.56), hypercholesterolemia (OR=1.33, 95% CI: 1.01 to 1.82), and hypertriglyceridaemia (OR=1.55, 95% CI: 1.01 to 2.37) were significantly related to NAFLD but these were not so for females.
Conclusions Several gender-related differences were noted pertaining to the prevalence of and relationship between hyperuricaemia, higher ALT, hypercholesterolemia, and hypertriglyceridaemia and NAFLD in the present study.
