Popis: The prevalence of the cardiovascular disease risk factors, dyslipidemia, hypertension, and diabetes mellitus, is increased in the setting of obesity.To determine whether the prevalence of these risk factors increases with increasing body mass index in an obese cohort, or whether there is a threshold for their appearance.Individuals with body mass indexor = 30 kg/m2 joined a weight reduction program in the Howard University General Clinical Research Center.Five hundred fifteen African Americans (aged 12-74 years, mean body mass index of 42.8 +/- 8.5 kg/m2).The cohort was divided by incremental increases in body mass index of 4.99 kg/m2, and the prevalence rates of hypertension (blood pressureor = 140/90 mm Hg), dyslipidemia (total cholesterol200 mg/dL, or low-density lipoprotein130 mg/dL, or elevated ratio of total or low-density to high-density lipoprotein cholesterol) and diabetes mellitus (fasting blood glucoseor = 126 mg/dL or random blood glucose200 mg/dL) were determined for each group.The cohort prevalence rates were: dyslipidemia, 27.0%; hypertension, 56.9%; and diabetes mellitus, 24.1%. These rates are higher than those found in the African-American population by the third National Health and Nutrition Examination Survey. After adjusting for age and sex, there were no significant differences in the prevalence rates of these risk factors according to increasing body mass index, suggesting a threshold of between 30 kg/m2-34.99 kg/m2 for maximal appearance of these risk factors.The incidence rates of dyslipidemia, hypertension, and diabetes mellitus do not increase with a greater degree of obesity above a body mass index of 34.99 kg/m2.
