摘要:
目的 分析并评估2023年新疆中小学生血压偏高的现状及其相关因素,为学生高血压的防控决策提供科学依据。 方法 按照分层整群随机抽样的方法,于2023年9—11月在新疆14个地州市抽取94 205名8~17岁中小学生进行身体测量和问卷调查。采用χ2检验比较不同特征学生的血压偏高率差异,采用Logistic回归模型分析中小学生血压偏高的相关因素。 结果 新疆中小学生的总体血压偏高率为8.18%,以单纯性收缩压增高(占比52.16%)为主要类型。按学段划分,四至六年级小学生、初中生、普通高中生、职业高中生的血压偏高率分别为8.04%,8.59%,7.65%和9.72%,差异有统计学意义(χ2=29.16,P < 0.01)。肥胖和超重学生的血压偏高率分别为9.93%和17.88%,高于体型正常学生的5.32%,差异有统计学意义(χ2=1 643.14,P < 0.01)。城市学生的血压偏高率(8.73%)高于农村学生(7.15%)(χ2=71.58,P < 0.01)。Logistic回归模型分析结果显示,女生的血压偏高风险高于男生(OR=1.06),初中生、普通高中生和职业高中生的血压偏高风险高于小学生(OR值分别为1.22,1.16,1.70),农村学生的血压偏高风险低于城市学生(OR=0.90),超重和肥胖组的血压偏高风险高于正常组(OR值分别为1.54,3.00),住校学生的血压偏高风险低于不住校学生(OR=0.71)(P值均 < 0.01)。 结论 新疆2023年中小学生有一定的血压偏高率,且以单纯性收缩压增高为主;需重点关注女生、城市、中学阶段、非住校及超重或肥胖中小学生。 Abstract:Objective To analyze and assess the current status of high blood pressure and associated factors among primary and secondary school students in Xinjiang in 2023, so as to provide a scientific basis for prevention and control decision-making of high blood pressure among students. Methods From September to November 2023, a total of 94 205 primary and secondary school students aged 8-17 from 14 prefectures and cities in Xinjiang, were selected for physical measurement and questionnaire survey using a stratified clustering random sampling method. The χ2 test was employed to compare differences in high blood pressure rates among students with varying characteristics. Additionally, a Logistic regression model was developed to analyze associated factors with high blood pressure among primary and secondary school students. Results The overall high blood pressure rate among primary and secondary school students in Xinjiang was 8.18%, with simple systolic hypertension being the main type at 52.16%. By educational stages, high blood pressure rates for elementary school (grades 4-6), middle school, high school and vocational high school were 8.04%, 8.59%, 7.65%, and 9.72% respectively (χ2=29.16, P < 0.01). The high blood pressure rates among obese and overweight students were 9.93% and 17.88% respectively, significantly higher than 5.32% among normal weight students (χ2=1 643.14, P < 0.01). The high blood pressure rate among urban students (8.73%) was higher than that of rural students (7.15%) (χ2=71.58, P < 0.01). Logistic regression model analysis showed increased high blood pressure risk for girls than boys (OR=1.06); middle school, high school, and vocational high school students had increased high blood pressure risk compared to elementary school students (OR=1.22, 1.16, 1.70); rural students had lower high blood pressure risk than urban students (OR=0.90); the risk of high blood pressure in overweight and obese groups was higher than that in the normal group (OR=1.54, 3.00), and the risk of high blood pressure in boarding students was lower than that in non boarding students (OR=0.71)(P < 0.01). Conclusions In Xinjiang in 2023, primary and secondary school students have a certain rate of high blood pressure, mainly characterized by elevated systblood pressure lower. The main prevention and control targets are females, urban residents, those in higher academic stages, non-boarding students, as well as overweight and obese primary and secondary school students. -
