The prevalence of hypertension in Chinese adolescents aged 15–17 years: A comparison of different criteria

Abstract

This study intended to compare the prevalence of hypertension in adolescents aged 15-17 years in China according to different criteria defined by various guidelines. We included 28 715 adolescents aged 15-17 years from the China Hypertension Survey study (CHS) 2012-2015, and the 2017 American Association of Pediatrics (AAP) Clinical Practice Guideline and 2018 Chinese guidelines for children and adults were used to define hypertension. The prevalence of hypertension among Chinese adolescents aged 15-17 years was 24.4% according to the 2018 Chinese guidelines for children; the corresponding values were 18.6% according to the 2017 AAP Guidelines, and 3.5% according to 2018 Chinese guidelines for adults. The age-specific prevalence of hypertension in the age of 15, 16, and 17 years in the same population was 26.2%, 24.4%, and 23.3% according to 2018 Chinese guidelines for children; 18.8%, 17.9%, and 19.2% as per the 2017 AAP Guidelines; 3.4%, 3.4%, and 3.6% as per the 2018 Chinese guidelines for adults. A highest prevalence of hypertension was observed according to 2018 Chinese guidelines for children than the other two guidelines. Compared with the 2018Chinese guidelines for children, a higher 95 th percentile BP (systolic and diastolic) was also observed in the present study in each gender-age-height-specific group. And the height, which was key factor to influence blood pressure, was similar between adolescents aged 15-17 and adults, and a paralleled result was seen in the present study.Therefore, the 2018 Chinese guidelines for adults may also be appropriate for adolescents aged 15-17 years.

Hypertension and Associated Risk Factors among Children with Intellectual Disability: A Cross-Sectional Study

“…Diverse classification criteria were adopted across studies, which may also play a role in the varied hypertension prevalence. Zhou et al (2022) compared three commonly used guidelines in 28,715 Chinese adolescents (aged 15–17 years) and found that the 2018 Chinese Guidelines for Prevention and Treatment of Hypertension for Children, which were used in our study, generated the highest prevalence rate of 24.4% [ 36 ]. The other two values were 18.6% for the 2017 American Association of Pediatrics Clinical Practice Guideline and 3.5% for the 2018 Chinese Guidelines for Prevention and Treatment of Hypertension for Adults.…”
