四川省西昌市2009-2011年初中学生肱动脉血压监测结果分析

Analysis of monitored brachial artery blood pressure of students from middle schools in Xichang during 2009 to 2011

目的利用西昌市中学生健康监测点,收集西昌市初中学生的肱动脉血压监测结果,分析西昌市初中学生肱动脉血压变化趋势,为当地制定防控青少年高血压等慢性非传染性疾病的相关政策、策略及措施提供可靠依据。方法根据西昌市初级中学的数量及分布情况,随机抽取1所全日制初级中学作为监测点学校。将监测点学校2009-2011年所有在校初中学生作为研究对象,由监测机构组织体检团队,于每年9-10月对研究对象开展体格检查,获取其肱动脉血压监测结果。结果 2009-2011年各年度研究对象超质量检出率分别为7.49%,7.89%及8.93%,肥胖检出率分别为3.08%,2.98%及3.04%,不同年度研究对象超质量检出率及肥胖检出率比较,差异均无统计学意义(P>0.05)。2009-2011年各年度研究对象的收缩压分别为(97.41±8.30)mmHg(1mmHg=0.133kPa),(98.72±8.07)mmHg及(101.67±9.52)mmHg,三者比较,差异有统计学意义(F=208.56,P<0.01),且两两比较结果显示,2011年研究对象收缩压均值高于2010年,而2010年高于2009年,差异均有统计学意义(P<0.05);2009-2011年各年度研究对象的舒张压分别为(62.35±5.08)mmHg,(62.55±5.46)mmHg及(64.00±5.61)mmHg,三者比较,差异有统计学意义(F=92.53,P<0.01),两两比较结果显示,2011年研究对象舒张压均值高于2010年,而2010年高于2009年,差异均有统计学意义(P<0.05)。不同性别研究对象2009-2011年各年度收缩压及舒张压的差异均有统计学意义(P<0.05)。结论西昌市初中学生肱动脉血压均值逐年上升趋势明显,今后当地疾病防治工作应重视青少年慢性非传染性疾病的早期预防。

Objective With data of health monitoring point of middle schools in Xichang to collect the brachial artery blood pressure monitoring results there and analyze the changing trend, therefore to provide reliable basis for the development of policies, strategies and measures in prevention and control of chronic non-communicable diseases such as hypertension in adolescents. Methods According to the quantity and distribution of mid- dle schools in Xichang, a full-time middle school was selected randomly as monitoring point. All the middle school students were regarded as objects of study and all the students had physically examined by team from monitoring organization every September and October from 2009 to 2011, thus the monitoring results of the brachial artery blood pressure were collected. Results From 2009 to 2011, the annual detection rates of over-weight were 7.49%, 7.89% and 8.93%, detection rates of obesity were 3.08%, 2.98% and 3.04%, when the detection rate of overweight and obesity of objects from different year compared, there were no statistically significant difference （P〉0.05）. Each year from 2009 to 2011 the research object of the systolic blood pressure were （97.41±8.30）mmHg （1 mmHg=0.133 kPa）, （98.72±8.07）mmHg and （101.67＋9.52）mmHg respectively, comparing the three, the difference was statistically significant （F=208.56, P〈0.01）; and comparing one to another, according to the results Of research, the systolic blood pressure of 2011 was higher than 2010,while the systolic blood pressure of 2010 was higher than that of 2009, and differences were statistically significant （P〈0.05）. Each year from 2009 to 2011 the diastolic blood pressure of research objects were （62.35± 5.08）mmHg, （62.55±5.46）mmHg and （64.00±5.61）mmHg respectively, comparing the three, the difference was statistically significant （F= 92.53, P〈 0.01） ; the comparison between one and another showed that in 2011 the diastolic pressures of the research objects were higher than that in 2010, and in 2010 the diastolic pressures of the research objects were higher than that in 2009, and the difference had statistical significance （P（0.05）. The difference between the systolic blood pressure and the diastolic blood pressure of objects with different gender showed statistically significance（P〈0.05）. Conclusion The brachial artery blood pressure of middle school students in Xiehang increases obviously annually, so the local prevention and control of chronic non-communicable diseases in adolescents should attach importance to the primary prevention.
