Does Good Aerobic Capacity Attenuate the Effects of Aging on Cardiovascular Risk Factors? Results from a Cross-Sectional Study in a Latino Population

الملخص EN

Background.

High aerobic capacity is associated with low cardiovascular (CV) risk.

The aim of this study was to determine the CV RF burden in subjects with aerobic capacity ≥10 METs and compare it with those having <10 METs.

Methods.

Cross-sectional study in 2646 subjects (mean age 48 ± 12 years).

Demographics, medical history, physical activity, cardiovascular RFs, fasting lipids and blood glucose levels, blood pressure, and anthropometric measurements were collected.

Aerobic capacity was determined by exercise stress test.

The ACC/AHA 2013 pooled cohort equation was used to calculate CV risk.

Logistic models were built to determine the probability of having ≥2 RFs versus 0‐1 RF, by age and sex, according to aerobic capacity.

Results.

15% of subjects had aerobic capacity<10 METs.

The ACC/AHA scores were 15% in men and 6% in women with <10 METs and 5% and 2%, respectively, in those with ≥10 METs.

The probability of having ≥2 RFs increased with age in both groups; however, it was significantly higher in subjects with <10 METs (odds ratio [OR]: 2.54; 95% CI: 1.92–3.35).

Conclusions.

Aerobic capacity≥10 METs is associated with a better CV RF profile and lower CV risk score in all age groups, regardless of gender.
