目的探讨中国人群血压的季节性变化以及影响因素.方法以中国慢性病前瞻性研究项目苏州点的基线调查(2004年11月至2008年6月)人群为对象(其中男性22 360人,女性30 900人),运用SAS统计软件分析比较调查期间人选对象的血压水平与室外气温的关系及联系强度和其他影响因素.结果在校正年龄等因素后,研究对象的冬季血压水平显著高于夏季,其中男性两季SBP差值为8.8 mm Hg,女性为7.0 mm Hg.SBP与气温(＞10℃时)呈显著线性负相关,室外气温每降低10℃,SBP升高6.1 mm Hg.血压的季节性差异在老年人和低BMI人群中更为显著.结论成人血压随室外温度的变化呈现较大的季节性波动.在高血压筛查、临床治疗以及流行病学调查分析中均应充分考虑血压的季节性波动变化.

Objective Seasonal variation in blood pressure had been observed in several studies on Western populations,but uncertainty remains about the strength of the relationship in other populations and the extent to which it was modified by other factors.Methods This study was based on cross-sectional data from the China Kadoorie Biobank study with 53 260 men and women from the Suzhou area involved.Linear regression model was used to analyze the association of blood pressure with outdoor temperature-overall and in various subgroups.Results Blood pressure varied with the seasons,ascending in winter and descending in summer.The difference in systolic blood pressure (SBP) between summer and winter was 8.8 mm Hg in men and 7.0 mm Hg in women.SBP was inversely correlated with outdoor temperature,especially above 10 ℃,with every 10 ℃ colder temperature causing 6.1 mm Hg increase of SBP.The seasonal variation in SBP was more obviously seen in older people and in those with lower body mass index.Conclusion Blood pressure was strongly and inversely associated with outdoor temperature in the population in Suzhou area.Seasonal variation of blood pressure should be considered when the hypertension screening programs,clinical management and data management on hypertensive patients.
