Correlation between testosterone, systolic blood pressure, body mass index and age in young males

Introduction: The prevalence of obesity in men has been related with changes in systolic blood pressure levels and testosterone. Objetive: The purpose of this study was to evaluate the relation among body mass index (BM l), systolic blood pressure (SBP) and testosterone at different ages in young males. Material and methods: In this work, was used a cross-sectional study, including a representative sample of 328 healthy males in ages 17 to 21 years old. BMI and SBP were evaluated using standard international procedures. The technique of immunoassay (ELISA) was used to measure concentration of testosterone. Results: The results showed that testosterone was positively associated to BMI in men with low weight (r = 0.135), normal weight (r = 0.395), overweight (r = 0.039) and inversely related (r = -0.130) with obese males. Other results, showed that testosterone was positively related to SBP in men with low weight (r = 0.406), normal weight (r = 0.922; p = 0.005), overweight (r = 0.673) and inversely associated (r = -0.144) with obese males. In addition, the testosterone was positively associated with the age in young males with low weight (r = 0.853) normal weight (r = 0.948; p = 0.005), overweight (r = 0.759) and obese men (r = 0.365). Conclusions: The results suggest that variations in testosterone levels were associated with changes to systolic blood pressure and this association can be mediated at least partially to obesity degree.
