Prevalence and correlation of vitamin D deficiency and high blood pressure in primary and middle school students in Chongqing

  Objective  To understand the status of vitamin D deficiency and high blood pressure in primary and middle school students aged 7 to 17 years old in Chongqing, and to explore the correlation between vitamin D deficiency and high blood pressure in children and adolescents.  Methods  From 2016 to 2017, a total of 1 360 primary and middle school students, aged 7 to 17 years old, were selected from three rural and three urban sites in Chongqing using multi-stage stratified random sampling. This study carried out a questionnaire survey, and participants underwent a physical examination which included blood pressure and serum vitamin D assessments.  Results  The deficiency and insufficiency rates of vitamin D were 9.71%, and 62.57%, respectively. The high blood pressure rate was 25.88%. Multivariate Logistic regression analysis showed that after adjusting for age, economic status, waist circumference, BMI classification, and family history of hypertension, the risk of hypertension was 1.42 times that of the normal group (P < 0.05), and the risk of high systolic blood pressure was 1.59 times that of the normal group (P < 0.05).  Conclusion  The deficiency and insufficiency rate of vitamin D among children and adolescents aged 7 to 17 years old in Chongqing was high, and the phenomenon of high blood pressure was prominent. Students with vitamin D deficiency and insufficiency were more likely to have high blood pressure.
