ABSTRACT
Objective@#To understand secular trend of blood pressure among Han ethnic students aged 7-18 years in Ningxia from 2000 to 2014，and to provide preliminary evidence for hypertension prevention and control.@*Methods@#Data of blood pressure, height, weight of Han students aged 7-18 years in Ningxia were collected in the National Students Physical Fitness and Health Survey during 2000-2014 years were analyzed by using SPSS 21.0.@*Results@#From 2000 to 2014, the systolic pressure of the Han students in Ningxia showed a decreasing-increasing trend(F=357.44, P<0.05), with an average decrease of 3.37 mm Hg; diastolic pressure showed a decreasing-increasing trend(F=172.95, P<0.05), with an average decrease of 4.18 mm Hg; pulse pressure showed a decreasing-increasing trend(F=311.86, P<0.05), with an average decrease of 1.98 mm Hg. The body mass index of the Han nationality students in Ningxia was on the rise(F=128.15, P<0.05). The detection rates of high blood pressure, high systolic blood pressure and high diastolic blood pressure increased by 1.0, 0.4 and 0.9 percentage.@*Conclusion@#Blood pressure in Ningxia Han students aged 7-18 years increases gradually in recent years, which warrants further attention. Health education and health promotion is needed to prevent the occurrence of hypertension.
