“…This study results in 2017 and 2018 were consistent with previous study in Yunnan [29]. But it differed from most of the study findings [30][31][32]. However, the prevalence of hypertension in boys was higher than that of girls for the first time in 2019 in Yunnan, which was consistent with the national study [30].…”

Background We aim to describe the prevalence and trends of hypertension among 9–17 school-aged students from 2017 to 2019 in Yunnan, China. Methods We conducted a cross-sectional study by using data from the Students’ Health Surveillance Surveys of 2017, 2018 and 2019 in Yunnan. The Students’ Health Surveillance Surveys in Yunnan collected date on physical fitness and health status of students in Yunnan through multistage-stratified sampling in 3 prefectures. In each prefecture, the study population were classified by gender and region (urban or rural), and each group had an equal size. Diagnosing criteria of hypertension was set with reference to Chinese age-specific and height-specific blood pressure (BP), to identify the abnormal status of boys and girls separately. ANOVA test was adopted to measure the differences in the mean BP stratified by gender, age, prefecture and area, and Chi-square test was used to compare the percentages of hypertension in different areas. For comparability, the age-standard and gender-standard population prevalence was calculated by directly using China Census in 2010 as a standard population. Totally 24,890 participants aged 9–17 years were included in this study. Results From 2017 to 2019, there were 24,872 students completed physical examinations and included in the analysis, of which 3288 were diagnosed with hypertension. The total prevalence of hypertension was 13.72, 12.49 and 13.45% among 9–17 years school-aged population in Yunnan, respectively. The total age-standardized hypertension prevalence trended to decrease from 13.82 to 13.48%. For urban population, the age-standardized hypertension prevalence decreased slightly from 11.24 to 10.13%. While, for rural population, it increased from 17.58 to 19.16%. The average annual growth rate in rural population was 0.53%. Conclusions From 2017to 2019, there was a significant and continuous increase in the prevalence of hypertension in 9–17 years school-aged population in Yunnan. Hypertension is epidemic among children and adolescents in Yunnan. We should take effective and comprehensive intervention measures to reduce its prevalence among school-aged children.

“…23 According to the KNHANES, total caloric intake and fat intake increased between 2007 and 2015 in children and adolescents. 24 Approximately 10% of middle and high school students performed vigorous physical activity for more than 30 minutes 5 days per week, and almost half of high school students slept less than 6 hours per day. According to the KNHANES, the daily time spent in moderate-to-vigorous physical activity has not changed between 2007 and 2015 among those aged 10-18 years.…”

Over the previous decades, the prevalence of pediatric obesity has been increased in Korea as well as worldwide. Pediatric obesity is associated with comorbidities in childhood and adulthood. We reviewed the prevalence of pediatric obesity using data from the National School Health Examination (NSHE) and the Korea National Health and Nutrition Examination Survey (KNHANES). Obesity was defined as a body mass index (BMI) ≥25 kg/m 2 ; BMI ≥95th percentile for the corresponding sex and age in the 2007 growth charts for the NSHE; or BMI ≥95th percentile for the corresponding sex and age in the 2017 growth charts for the KNHANES. There was a slight discrepancy in the prevalence of obesity depending on the data source. The prevalence of obesity increased from 8.7% in 2007 to 15.0% in 2017 in the NSHE (in children aged 6-18 years) and from 8.6% in 2001 to 9.8% in 2017 in the KNHANES (in children aged 2-18 years). The increase in the prevalence of obesity was higher in boys and high school students. Accurate epidemiologic data analyzed using the new 2017 growth charts are essential in developing strategies for controlling obesity. Efforts to collect more reliable nationally representative data, including longitudinal studies, are warranted. tween 2001 and 2014 had plateaued. Prevalence studies on pediatric obesity using the new 2017 growth charts are not available. In this review, we discuss the up-to-date epidemiologic data on overweight and obesity among Korean children and adolescents.

“…And the difference in prevalence was caused by the age difference between subjects and the method of analysis.The prevalence of elevated blood pressure and hypertension in children is reported around 6% and 3%, respectively(9,29). In obese adolescents, the combinded prevalence increases to around 30%(29).Cho H et al reported the prevalence of hypertension increased over time, it was from 6.9% (KNHANES 2007-2009) to 9.0%, (KNHANES 2013-2015) in Korean children and adolescent aged 10-18 year(30). The prevalence of HTN were higher in boys than girls, and increased with severity of obesity.…”

Objective: To investigate investigated the association of hemoglobin (Hb) concentration, hematocrit (Hct) and blood pressure (BP) in children and adolescents.Methods: The study population consisted of a total 7,950 subjects (4,229 boys, 3,721 girls) aged 10 to 18 years who participated in the Korea National Health and Nutrition Examination Surveys conducted between 2007 and 2017.Results: The prevalence of hypertension is estimated about 19.19% (21.51% for boys and 16.5% for girls). The prevalence of obesity is estimated about 9.59% (10.5% for boys and 8.6% for girls). Hb and Hct level tended to increase with the degree of obesity and blood pressure. The systolic BP (SBP) and diastolic BP (DBP) have positively correlated with Hb and Hct levels in both sex. In the multiple regression analysis, the Hb and Hct presented positive association with SBP and DBP after adjustment for for age, BMI SDS, alcohol consumption, smoking physical activity, rural residence, household income, diagnosis of T2DM, hypertension, and dyslipidemia.Conclusion: Hemoglobin and hematocrit levels were positively associated with SBP and DBP, in children and adolescent, aged 10- 18 year.
