Clinical and epidemiological aspects of blood pressure in pediatric population of the north coast axis center in Venezuela evaluated in the SENACREDH: III. Anthropometric and biochemical variables associated with blood pressure

In the context of the Second National Study of Human Growth and Development of the Bolivarian Republic of Venezuela (SENACREDH), blood pressure was evaluated in 4 017 individuals 6.00 to 19.99 years-old from Carabobo, Aragua, Miranda, Vargas states and Capital District. Multiple regression models with anthropometrical and biochemical variables for the blood pressure were done. Prevalence of isolated blood pressure =P90 (Prehypertension and hypertension) systolic was 4.36 % and diastolic 4.62 %. Those with body mass index in excess presented significantly higher prevalences of systolic blood pressure, P90 to P95 (6.3 %), P95 to P99 (4.1 %), =P99 (0.9 %) compared to those with a normal body mass index P90 to P95 (1.2 %), P95 to P99 (0.7 %), =P99 (0.3 %). Similar findings were found for diastolic blood pressure. Those with a total cholesterol/HDL index =4.0 presented significantly higher prevalences of systolic blood pressure, P90 to P95 (3.1 %), P95 to P99 (1.7 %), =P99 (0.6 %) compared to those with 4.0 P90 to P95 (1.7 %), P95 to P99 (1.1 %), =P99 (0.3 %). Similar findings were found for diastolic blood pressure. At multiple regression body mass index and waist circumference are predictor of systolic blood pressure (P0.001). Waist circumference also for diastolic blood pressure (P0.001). These variables are significantly associated as predictors of blood pressure, then its assessment in the integral cardiovascular evaluation should be done not just for classification but also as potential risk estimation for hypertension.
