title: Correlates of blood pressure in elementary schoolchildren.
abstract: This cross-sectional study determined which anthropometric, dietary, and physical fitness variables were best predictors of blood pressure (BP) in 323 white elementary schoolchildren. Height, weight, triceps, and subscapular skinfold thickness were measured, followed by two resting BP measurements. Cardiorespiratory fitness was assessed by time in a one mile run. A food frequency questionnaire measured habitual dietary intake. Correlational analysis revealed height, weight, body mass index (wt/ht2), and skinfold thicknesses were anthropometric variables associated significantly with both systolic and diastolic blood pressure. Physical fitness was not correlated with BP and, among dietary variables, only estimated daily caloric intake, dietary cholesterol, and nondiscretionary sodium were related to blood pressure. A multiple regression analysis selected weight, body mass index (BMI), and total caloric intake as factors explaining the greatest amount of BP variability. For some individuals, hypertension may originate in childhood, thus, these results could have implications for primary prevention of high blood pressure.
