Analysis of the effect of glutamyltransferase on hyperlipidemia based on decision tree

ObjectivesThis study is designed to analyze the potential influencing factors of hyperlipidemia, and to explore the relationship between liver function indicators such as gamma-glutamyltransferase (GGT) and hyperlipidemia. MethodsData were derived from 7599 outpatients who visited the Department of Endocrinology of the First Hospital of Jilin University (2017-2019). A multinomial regression model is used to identify related factors of hyperlipidemia and the decision tree method is used to explore the general rules in hyperlipidemia patients and non-hyperlipidemia patients on these factors. ResultsThe average of age, body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure, aspartate aminotransferase, alanine aminotransferase (ALT), GGT and glycosylated hemoglobin (HbA1c) in the hyperlipidemia group are higher than those in the non-hyperlipidemia group. In multiple regression analysis, SBP, BMI, fasting plasma glucose, 2-h postprandial blood glucose, HbA1c, ALT, GGT are associated with triglyceride. For people with HbA1c less than 6.0%, controlling GGT within 30 IU/L reduces the prevalence of hypertriglyceridemia by 4%, and for people with metabolic syndrome with impaired glucose tolerance controlling GGT within 20 IU/L reduces the prevalence of hypertriglyceridemia by 11%. ConclusionsEven when GGT is in the normal range, the prevalence of hypertriglyceridemia increases with its gradual increase. Controlling GGT in people with normoglycemia and impaired glucose tolerance can reduce the risk of hyperlipidemia.

Automated summary

This study aims to analyze potential influencing factors of hyperlipidemia and explore the relationship between liver function indicators, such as gamma-glutamyltransferase (GGT), and hyperlipidemia. Data from 7599 outpatients were analyzed, showing that factors such as age, body mass index (BMI), blood pressure, liver enzymes (ALT, GGT), and glycosylated hemoglobin (HbA1c) were associated with hyperlipidemia. Controlling GGT levels within specific ranges can reduce the risk of hypertriglyceridemia in certain populations, such as those with normoglycemia or impaired glucose tolerance.
