Background: Physical inactivity, excess body weight, smoking, alcohol consumption were widely described as factors-related to chronic diseases development, leading to 5.7 million
deaths per year.This paper aimed to identify the relationship between physical activity level (PAL) and body mass index as predictor to the development of non alcoholic hepatic steatosis (HS) in both
Methods: The study evaluated 2.251 both sex subjects (41.4± 7.4 years) with body mass index of 25.4 kg/m2 (±4.0) that don’t have risk alcohol consumption according Alcohol Use
Disorder Identification Test, who participated in the Protocol of Preventive Medicine Center/ Check-up at Hospital Israelita Albert Einstein- São Paulo/ Brazil, from January to October 2011. The
individuals was underwent anthropometric evaluation- Body Mass index (BMI) (above 25 kg/m2 until 29,99 kg/m2 was considered overweight, above 30,0 kg/m2 was obese) and waist circumference (women have
circumference above 88 cm and men over 102 cm is considered high risk factor), medical history, the Physical Activity Level was evaluated with IPAQ (International Physical Activity Questionnaire) and
trunk ultrasound to identify hepatic steatosis (HS). The statiscal analysis was based in qui square test and logistic regression with significance level p<0.5.
Results: Data showed that 29.1% presented positive diagnose to HS. The PAL presented that 66.3% of both sex adults were physically inactive with less than 150 minutes of physical
activity per week. The associating between PAL and the HS data evidenced that 88.97% with positive HS were physically inactive. The association of BMI as criteria do the excess body weight was twice
related increased to HS in obese I, II and III adults with relative risk from 7.4, 18.7 and 5.0 respectively, compared to normal weight adults. These data suggests that overweight has to be strongly
considered to HS prevalence. Similar trend was found to waist circumference criteria, presenting 1.2 higher risk to HS development.
Conclusions: Considering that physical activity provides an protection to metabolic disorders (weight control, dyslipidemia, HDL increase) to HS development, we may point out that
anthropometric (body mass index) can be considerable predictor of non alcoholic HS, with stronger association to HS than WC.
