目的了解唐山市中小学生体质量指数和高血压患病率的基本情况,为开展学生乃至全民高血压的早期预防提供科学依据。方法从唐山市所辖区县的中小学校采用分层整群随机抽样的方法抽取3 746名学生,测量指标包括身高、体重、收缩压和舒张压。结果正常体重、超重、肥胖学生高血压患病率分别为1.54%,7.61%,34.31%,差异有统计学意义(χ2=651.80,P<0.05);城市学生高血压患病率和超重肥胖率分别为7.77%,10.87%,农村分别为1.85%,5.38%,差异均有统计学意义(χ2值分别为71.05,37.60,P值均<0.05);男生高血压患病率为6.41%,女生为2.90%,差异有统计学意义(χ2=24.74,P<0.05),而超重肥胖率性别间差异无统计学意义(χ2=0.78,P>0.05)。结论唐山市中小学生高血压患病率与体质量指数呈正相关,提示应把超重肥胖学生作为一级预防的重点人群。
Objective To understand the basic situation of the body mass index and the prevalence of hypertension in primary and secondary school students in Tangshan and provide a scientific basis for the early prevention of hypertension among students and even the whole nation. Methods A total of 3 746 students were enrolled from primary and secondary schools in counties under the jurisdiction of Tangshan City by means of stratified cluster random sampling. The measurement indexes included height, weight, systolic blood pressure and diastolic blood pressure. Results The prevalence rates of hypertension in normal weight, overweight and obese students were 1.54%, 7.61% and 34.31%, respectively, with statistical significance (χ2 = 651.80, P <0.05). The prevalence of hypertension and overweight and obesity Respectively (7.77%, 10.87%, respectively, 1.85%, 5.38% in rural areas, the differences were statistically significant (χ2 values were 71.05,37.60, P values were <0.05; prevalence of hypertension was 6.41% The difference was statistically significant (χ2 = 24.74, P <0.05), while there was no significant difference between the sexes in overweight and obesity (χ2 = 0.78, P> 0.05). Conclusion The prevalence of hypertension in primary and secondary school students in Tangshan is positively correlated with body mass index, suggesting that overweight and obese students should be regarded as the key population for primary prevention.
