Relationship between increased serum activity of alanine aminotransferase and metabolic parameters in non-alcoholic population / 中华全科医师杂志

ABSTRACT

Objective The aim of this study is to identify association between increased serum activity of alanine aminotransferase (ALT) and metabolic parameters in non-alcoholic population of north China. Methods A total of 5351 subjects who came to visit Yuquan Hospital of Tsinghua University for health examinations during May to December 2007 were divided into two groups based on their serum ALT activities, one with equal to or more than 40 U/L and the other with less than 40. Anthropometric data, blood pressure, serum ALT, serum levels of triglyceride (TG), total cholesterol (TC), high-dense lipoprotein-cholesterol (HDL-C), low-dense lipoprotein-cbolesterol (LDL-C) and fasting blood glucose (FBG) were measured for all of them. Results Body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), TG, TC, HDL-C, LDL-C and FBG were significantly different between the two groups. BMI, TG, TC, HDL-C, LDL-C and FBG all associated with increased ALT both in males and females. DBP associated with increased ALT in males and SBP with it in females, logistic regression analysis showed that male, younger age, raised BMI, TG, TC, FBG and reduced HDL-C were strongly associated with increased serum ALT. Conclusions Results showed that metabolic disturbance such as obesity, hypertension, dyalipidemia, hyperglycemia, and so on associated with increased ALT in non-alcoholic population of north China.
