Researchers found that childhood BMI and insulin levels were significant predictors of adult Syndrome X clustering obesity, hyperinsulinemia, high blood pressure, and adverse levels of total cholesterol and triglycerides.

The purpose of the trial was to examine the independent effects of equivalent diet- or exercise-induced weight loss on obesity and related cardiovascular health risk factors.

All of the mechanisms by which obesity influences blood pressure are to date not totally understood; what is clear is that obesity-related hypertension is a well-documented phenomenon that is multifactorial and complex. The increased production reduction in obesity and related comorbid conditions cholesterol in obese persons also results in the increased incidence of gallstones in both men and women.
