苏州市中学生超重和非超重状态下腰围预测罹患血压偏高的风险性研究

Waist circumference predicts the risk of hypertension in overweight and non-overweight middle school students in Suzhou

摘要:

目的 探讨苏州市中学生超重和非超重状态下腰围（WC）预测血压偏高的风险性，为开展相关研究和干预提供依据。方法 采用问卷调查和体格检查相结合的方式采集苏州市8所中学的963名中学生的WC、体质指数（BMI）和血压值。应用Logistic回归分析探索中学生WC与血压偏高的关联性。结果 963名中学生在调整混杂因素前后，非超重组WC每变化1cm血压偏高风险分别提高至1.08（1.03~1.14）和1.07（1.02~1.13），超重组WC每变化1cm血压偏高风险分别提高至1.05（1.02~1.09）和1.05（1.01~1.08）。结论 苏州市中学生超重与非超重状态下WC与血压偏高均呈正相关（P<0.01），非超重组比超重组WC每变化1cm发生血压偏高风险高 。在关注超重组中学生的WC的同时应重视非超重组的WC变化情况，及时采取干预措施降低血压偏高发生风险。

Abstract:

Objective To explore the ability of waist circumference (WC) to predict hypertension risk in overweight and non-overweight middle school students in Suzhou. Methods The height, weight，WC and blood pressure values of 963 students from 8 middle schools in Suzhou were collected by a combination of questionnaire survey and physical examination. Logistic regression analysis was applied to explore the correlation between WC and high blood pressure in middle school students. Results Logistic regression analysis showed that before and after adjusting for confounding factors, for every 1 cm change in WC, the risk of high blood pressure increased to 1.08 (1.03-1.14) and 1.07 (1.02-1.13) for non-overweight students, and 1.05 (1.02-1.09) and 1.05 (1.01-1.08) for overweight students, respectively. Conclusion There was a positive correlation between WC and high blood pressure in both non-overweight and overweight middle school students in Suzhou. The risk of high blood pressure was higher for non-overweight students than overweight students for every 1 cm WC change. Targeted intervention measures should be taken to reduce the prevalence rates of hypertension for middle school students.
