目的:了解茂县农村居民低血压患病情况,探讨低血压的危险因素。方法:利用在茂县抽样调查的人群资料,进行低血压的横断面研究。10～14岁儿童低血压标准为:收缩压(SBP)≤80mmHg(1mmHg=0.133kPa)或者舒张压(DBP)≤50mmHg,15岁以上低血压标准为:SBP≤90mmHg或者DBP≤60mmHg。结果:男性和女性的低血压患病率分别为8.2%和12.2%。从低年龄组到高年龄组(10岁～、20岁～、40岁～、60岁～),低血压的患病率分别为17.3%、12.3%、4.8%、5.5%。Logistic回归分析显示,年龄(OR=0.566,95%CI0.406～0.789)、性别(OR=1.999,95%CI1.171～3.411)和民族(OR=6.967,95%CI2.322～20.905)与低血压状态相关。结论:低年龄组人群是低血压的高发人群,女性和非羌族人群在当地可能是易患人群,这为进一步探索低血压的病因提供了线索。
Objective: To understand the prevalence of hypotension among rural residents in Maoxian County and to explore the risk factors of hypotension. Methods: A cross-sectional study of hypotension was conducted using population data from a sample survey in Mao County. The standard of hypotension for children aged 10-14 years: systolic blood pressure (SBP) ≤80mmHg (1mmHg = 0.133kPa) or diastolic blood pressure (DBP) ≤50mmHg, SBP≤90mmHg or DBP≤60mmHg for children over 15 years old. Results: The prevalence of hypotension in both men and women was 8.2% and 12.2%, respectively. The prevalence of hypotension was 17.3%, 12.3%, 4.8%, and 5.5%, respectively, from the lower age group to the upper age group (10 years old, 20 years old, 40 years old, 60 years old). Logistic regression analysis showed that age (OR = 0.566,95% CI0.406-0.789), gender (OR = 1.999,95% CI1.171-3.411) and ethnicity (OR = 6.967,95% CI2.322-20.905) Hypotension related. CONCLUSIONS: The low-age population is a high prevalence of hypotension. Female and non-Qiang populations may be predisposed to the disease locally, providing a clue to further explore the underlying causes of hypotension.
