Abstract

Aim

To discuss the prevalence and associated factors related to an elevated serum alanine aminotransferase (ALT) level among the elderly agricultural and fishing population.

Methods

A total of 6542 (3989 males and 2553 females) healthy adults voluntarily admitted to a teaching hospital for a physical checkup in 2010 in Taipei, Taiwan. Fasting blood samples were drawn via venipuncture, and clinical nurses interviewed the study participants using a structured questionnaire from.

Results

The overall prevalence of an elevated serum ALT level was 18.2% and revealed a statistically significant decrease with increasing age (P < 0.001). The men exhibited a higher prevalence than the women (19.7% vs 15.9%; P < 0.001). Male sex; younger age; and presence of obesity, hypertension, hyperuricemia, and hypoalbuminemia were significantly associated with an elevated serum ALT level. Sex-related differences were also revealed. For the men, type 2 diabetes (odds ratio [OR], 1.23; 95% confidence interval [CI], 1.02–1.57), hypercholesterolemia (OR, 1.78; 95% CI, 1.22–2.83), hypertriglyceridemia (OR, 1.32; 95% CI, 1.04–1.73), and low high-density lipoprotein (OR, 1.26; 95% CI, 1.05–1.51) were significantly related to an elevated serum ALT level, but this was not so for the women. The disparity of ALT in age groups was revealed.

Conclusion

Several sex-related differences were indicated pertaining to the prevalence of an elevated serum ALT level among elderly specific occupational population.
