Introduction:

In the pathology of metabolic syndrome, manifestations of liver damage have been seen in different investigations and in clinical practice.

Objective:

To estimate the prevalence of elevated transaminases (alanine aminotransaminase and aspartate aminotransaminase), and to determine their association with metabolic syndrome.

Methods:

Cross-sectional with analytical procedure study. Secondary analysis of data generated by the electronic health record of an occupational polyclinic. The main variable was the diagnosis of metabolic syndrome. To define elevated aspartate aminotransaminase, values > 30 U/L in women and values > 36 U/L in men were considered. For alanine aminotransaminase, values > 30 U/L in women and values > 40 U/L in men were considered.

Results:

The prevalence of metabolic syndrome was 21.82%, elevated aspartate aminotransaminase was 10.30% and elevated alanine aminotransaminase was 16.67%. In multiple regression, we adjusted for the confounding covariates of sex, age, occupation, body mass index, smoking, alcohol and physical activity. It was observed that patients with elevated aspartate aminotransaminase had a 128% higher frequency of presenting metabolic syndrome, compared to those without elevated values (reason prevalence= 2.28; 95% CI: 1.64-3.17; p< 0.001). On the other hand, it was found that patients with elevated alanine aminotransaminase had a 148% higher frequency of presenting metabolic syndrome compared to those without elevated values (reason prevalence= 2.48; 95% CI: 1.77 - 3.47; p< 0.001).

Conclusions:

There is an association between elevated hepatic transaminases and the presence of metabolic syndrome.
