obesity measures and elevated levels of alanine aminotransferase: a population based study
نویسندگان
چکیده
background: obesity may lead to various morbidity including liver diseases. the present study was done to determine which obesity indices, including body mass index (bmi), waist circumference (wc), waist to hip ratio (whr), and waist to height ratio (whtr) have the stronger association with rising levels of alanine aminotransferase (alt). material and methods: of 6143 subjects aged ≥ 10 years of a cohort study in northern iran, the data of 5052 subjects were analyzed. we performed multivariate logistic regression analyses for data of men and women, separately. in multivariate analyses the obesity measures were separately included in model in addition to other potential confounders. a high value of alt was considered as outcome. the capability of obesity indices to discriminate an elevated level of alt was evaluated using receiver operating characteristic (roc). results: based on our results, men and women with obesity showed significantly higher values of liver enzymes for all obesity indices. in multivariate analysis, while whtr showed the strongest association with a high value of alt in men [wald=91.44; or=3.348, 95%ci (2.613-4.289); p<0.001], wc showed the strongest association in women [wald=26.76; or=1.724, 95%ci (1.402-2.119)]. conclusion: whtr in men and wc in women have more independent association with elevated levels of alt.

Sex-Specific Association between Metabolic Abnormalities and Elevated Alanine Aminotransferase Levels in a Military Cohort: The CHIEF Study
The association of metabolic syndrome (MetS) components with elevated serum alanine aminotransferase (ALT) levels, a marker of hepatic injury, may differ between men and women. However, the sex-specific association in a military young population which has a low prevalence of MetS was unclear. We conducted a cross-sectional examination in 6738 men and 766 women, aged 18-50 years, from the cardio...

BACKGROUND & AIMS Elevated serum alanine aminotransferase (ALT) and gamma-glutamyltransferase (GGT) activities are markers of liver injury, but may also be associated with other diseases and death. In a prospective, national, population-based sample, we examined whether elevated ALT and GGT were associated with increased risk of all-cause and disease-specific mortality. METHODS Death certific...

BACKGROUND Elevated alanine aminotransferase (ALT) levels may be associated with metabolic syndrome and cardiovascular diseases. This study aimed to investigate the association between elevated ALT levels and cardiometabolic risk factors in a rural Chinese population. METHODS This was a cross-sectional study conducted from July 2012 to August 2013, including 11,573 subjects (5,357 men and 6,2...
