The Correlation Between Body Weight and Arterial Blood Pressure in 11 and 15 Years Old Children: Retrospective Cross-Sectional Study

Abstract

Background. Children’s body weight is the predictor of pathologic elevation of arterial blood pressure (ABP) in adult life. The aim of the study is to divide the data on body weight and ABP in adolescents and to find correlations between them. Methods. The randomised study of 11 and 15 years old pupils from general education institutions was carried out. The 16 months research was executed in 9 different regions of the country (one region from every federal district and 5 schools (with juniors and seniors) in each were randomly selected). In addition to measurement of ABP (three times by Korotkov’s method) and body weight (using general bathroom scales) all children were examined by the group of pediatric specialists (pediatrician, gastroenterologist, allergologist, otolaryngologist, ophthalmologist, neurologist, psychologist, cognitive specialist, orthopedic traumatologists, nephrologist, ultrasound and laboratory diagnostic specialist).Results. The study included 1911 teenagers. The correlation (p<0,010 for all groups) between systolic/diastolic blood pressure and body weight was revealed in group of boys at the age of 11 (r=0,394/0,206) and 15 (r=0,231/0,185) years old and in group of girls of the same age age (r=0,330/0,227 and r=0.228/0.148 respectively). Conclusion. The significant correlation between body weight and levels of systolic and diastolic blood pressure in 11 and 15 years old children has been revealed.
