Objective
To determine the impact of physical activity on the prevalence of fatty liver, metabolic and cardiovascular disease in adult men.
Methods
This study evaluated 1,399 men (40.7±8.18 years) with body mass index of 26.7kg/m2 (±3.4) who participated in the Protocol of Preventive Health Check-up at Hospital Israelita Albert Einstein from January to October 2011. We conducted tests of serum blood glucose, total cholesterol, LDL, HDL, triglycerides, reactive c-protein, aspartate transaminase, alanine transaminase and gamma-glutamyl transpeptidase. The statistical analysis comprised in the comparison of mean and standard deviation. The analysis of variance was based in two paths of two way ANOVA, Student’s t-test, Mann Whitney U test, Wald test and χ2. We considered a significance level at p<0.05 and correlation of univariate Poison with 95% confidence interval.
Results
Fatty liver was diagnosed in 37.0% of the sample. Triglyceride levels of active men with fatty liver were 148.2±77.6mg/dL while inactive men with fatty liver had 173.4±15.6mg/dL. The remaining serum levels were normal. Inactive individuals showed higher values than active. In addition, inactive individuals have 10.68 times higher risk of developing fatty liver compared with active.
Conclusion
Physical activity improves metabolic parameters such as triglycerides, weight control, HDL, which interfere in the development of fatty liver. Physically active individuals had lower fatty liver prevalence regardless of values of body composition and lipid profile, leading the conclusion that physical activity has a protective role against development of fatty liver.
