Waist-stature ratio can indicate the risk of cardiovascular disease even in healthy men

Publicado em 28 janeiro 2019

The study found that physically active men who were not overweight but whose waist-stature ratio (WSR) was close to the risk threshold were also more likely to develop heart disorders than individuals with lower WSRs.

The study was conducted by Brazilian researchers affiliated with São Paulo State University (UNESP) in Presidente Prudente and Marília in collaboration with colleagues at Oxford Brookes University in the UK. The study resulted from a research project supported by São Paulo Research Foundation - FAPESP and is published in the journal Scientific Reports.

Individuals - History - Metabolic - Disease - WSRs

"We found that non-overweight, physically active, healthy individuals without a history of metabolic or cardiovascular disease but with WSRs close to the risk factor limit were more likely to develop heart disorders than individuals with less accumulated fat in the waist area," Vitor Engrácia Valenti, a professor at UNESP Marília and principal investigator for the study, told.

According to Valenti, recent research suggests that the WSR (waist circumference divided by height) is a more accurate predictor of cardiovascular risk than the body mass index (BMI), a widely used measure of body fat.

Researchers - Hypothesis - Recovery - Heart - Rate

The researchers further investigated this hypothesis by analyzing the autonomic recovery of heart rate after aerobic exercise in healthy men with different WSRs. To this end, 52 physically active healthy men aged 18-30 were divided into the following three groups according to WSR: between 0.40 and 0.449, which is below the risk threshold for cardiovascular disease; between 0.45 and 0.50, which is close to the threshold; and between 0.50 and 0.56, which is above the threshold.

The participants were tested on two separate days with a 48-hour interval between the two tests. On the first day, they remained seated and at rest for 15 minutes, and then performed a maximum effort test on a treadmill. After this bout of aerobic exercise, they remained standing and...
