Abstract

Objective To determine the relationship between primary hypertension and obesity in 3-18-years-old children and adolescents of Changchun City so as to provide scientific basis for early prevention of hypertension. Methods Children aged from 3 to 18 years were sampled by random-cluster. Height, weight, waist circumference and blood pressure were measured. Questionnaire survey, t-test, and Chi-squared test were conducted. Pearson correlation analysis and multivariate Logistic regression analysis of the data were used. Results (1)The prevalence of hypertension was 8.9%. The prevalence of overweight and obesity was 20.9%. The peak of obesity was found at the age of 9 to 11 years. (2) The incidencies of hypertension in overweight and obesity groups were 13.17% and 32.85%,respectively significantly higher than in the normal weight group(5.3%). The influence of BMI on systolic blood pressure was greater than its influence on diastolic blood pressure.(3)BMI, waist circumference, waist height ratio (WHtR) were positively correlated with systolic blood pressure and diastolic blood pressure. The correlation between waist circumference and BMI with blood pressure was greater than WHtR; there was no significant gender differences. (4) The incidence of overweight and obesity was 56.3% in adolescents with overweight family history, and it was 18.7% in adolescents without overweight history (P<0.05). (5)Children with high blood pressure were more likely to be inflicted with hyperglycemia and lipid metabolism disorder. BMI, waist circumference and serum lipids were the main factors influencing the blood pressure. BMI significantly influenced systolic blood pressure whereas waist circumference significantly influenced diastolic blood pressure(P<0.05). Conclusions Hypertension in children and adolescents can be predicted sensitively by BMI. At present, incidence of overweight and obesity has increased significantly in China. The intervention against overweight, obesity and hypertension among children and adolescents should be concerned with by local government, schools and parents.
