Abstract:
Objective:To investigate the prevalence of high blood pressure in adolescent children and adolescents in Jiamusi, Heilongjiang Province, China. To analyze age , gender-and age* gender-spectific classification of blood pressure to height ratio for screening high blood pressure in adolescence.
Methods:Anthropometric parameters were measured in 26 068 Han students aged 10 to 17 participating in the routine physical examination in Jiamusi, Heilongjiang Province. Using the receive operating characteristic curve to determine the cutoffs for screening high blood pressure by three classification methods. The area under curve( AUC ), sensitivity, specificity, positive likelihood ratio (+ LR ), negative likelihood ratio (- LR ), positive predictive value (PPV ), negative predictive value ( NPV ), and Kappa value were used for evaluation.
Results:The detection rate of high blood pressure in children and adolescents was 22.7%. When screening high blood pressure in adolescence, the AUC , sensitivity, specificity, +LR, -LR, PPV, NPV , and Kappa values of the gender classification were 0.87, 95.0%, 79.1%, 4.56, 0.06, 57.2%, 98.2% , 0.60, respectively; the age classification were 0.89, 93.3%, 84.5%, 6.04, 0.08, 64.0%, 97.7%, 0.67, respectively; the age-gender classification were 0.90, 94.3%, 85.5%, 6.52, 0.07, 65.7%, 98.1%, 0.69, respectively. The sensitivity, specificity and negative predictive values of the three methods were higher, but the positive predictive value was lower. The age-gender classification had the highest AUC and Kappa value and the lowest were gender classification.
Conclusion:The age-gender classification has the best screening effect, but it is relatively complicated. The age classification has a good screening effect and it is more convenient. Both methods are recommended for screening for high blood pressure during puberty.
