[Blood pressure changes in 18-59 years old adults in rural area of Shanxi province, China].

Objective: To analyze the blood pressure changes of adults aged 18-59 years in rural area of Shanxi province based on a cohort study, and provide reference for the study of the blood pressure level of rural residents and hypertension prevention and control in rural areas in China. Methods: Data were obtained from Shanxi Nutrition and Chronic Disease Family Cohort from 2002 to 2015. Subjects aged <18 years or ≥60 years and individuals with hypertension at baseline survey in 2002, and those who had taken antihypertensive drugs for nearly two weeks during the follow-up survey in 2015 were excluded from the study. A total of 1 629 subjects aged 18-59 years were included in the analyses of the blood pressure level and its change from the baseline survey in 2002 to follow-up survey in 2015. Results: The systolic blood pressure (SBP) of the subjects increased from (122.7±10.4) mmHg in 2002 to (132.8±17.6) mmHg in 2015 and the diastolic pressure (DBP) increased from (72.7±6.9) mmHg in 2002 to (78.8±10.3) mmHg in 2015. The SBP in men and women increased with growth rates of 6.7% and 9.5%. While DBP in men and women increased with growth rates of 9.3% and 7.8%. The SBP levels of those aged 18-, 30-, 40- and 50-59 years increased with growth rates of 5.0%, 6.7%, 9.4% and 11.8%. While the DBP of these age groups increased with growth rates of 12.2%, 8.2%, 8.2% and 6.5%. Conclusions: The blood pressure of adults aged 18-59 years old in rural area of Shanxi showed a substantially increasing trend. The mean increase level of SBP in women was higher than that in men, and increased with age. While the mean increase level of DBP in men is higher than that in women, and decreased with age.目的： 分析山西省农村地区18~59岁居民血压水平及其变化情况，为探索我国农村地区血压水平及防控措施提供参考。 方法： 研究对象来自山西营养与慢性病家庭队列，剔除2002年基线调查时年龄<18岁或年龄≥60岁研究对象、基线时患有高血压的个体和2015年随访调查时近2周正在服用降压药物者，共纳入1 629名基线调查时18~59岁的调查对象，分析2002年基线调查和2015年随访调查时的血压水平及变化情况。 结果： 2002年18~59岁人群的SBP由（122.7±10.4）mmHg（1 mmHg=0.133 kPa）增长至2015年的（132.8±17.6）mmHg，DBP由（72.7±6.9）mmHg增长至（78.8±10.3）mmHg，男性和女性SBP增长率分别为6.7%和9.5%。男性和女性DBP增长率分别为9.3%和7.8%。18~、30~、40~和50~59岁年龄组人群SBP增长率分别为5.0%、6.7%、9.4%和11.8%。而DBP增长率分别为12.2%、8.2%、8.2%和6.5%。 结论： 山西省农村地区18~59岁居民SBP和DBP均值水平均呈现明显的增长趋势，SBP增加水平呈现女性高于男性，随年龄增加而递增趋势，DBP增加水平呈现男性高于女性，随年龄增加而递减的趋势。.
