Season is one of the factors affecting blood pressure. The objectives of this study are to quantify the magnitude of seasonal changes in blood pressure among normotensive women aged 18 to 40 years and to find out the association of blood pressure variation between winter and summer with body mass index, temperature, humidity, day length, and salt intake. The study was carried out on 132 women, included 4 home visits during the seasons of spring, summer, autumn, and winter. Mean increase in systolic blood pressure (SBP)/diastolic blood pressure (DBP) in winter was 11.07/6.79 mm Hg during summer (P < .001). No significant relationship in blood pressure variation with change in environmental variables was observed. Mean increase in SBP/DBP in winter was more among underweight than individuals who were normal/overweight/obese (P < .05). There was significant increase in SBP/DBP during winter compared with summer. This seasonal factor should be considered while evaluating individual blood pressure and comparing community studies.
季节是影响血压的因素之一。本研究的目的是量化 18 至 40 岁正常血压女性的血压季节性变化幅度，并找出冬季和夏季血压变化与体重指数、温度、湿度、日照时间和盐摄入量之间的关系。该研究共纳入了 132 名女性，在春夏秋冬四季进行了 4 次家访。与夏季相比，冬季收缩压（SBP）/舒张压（DBP）平均升高 11.07/6.79mmHg（P<.001）。未观察到血压变化与环境变量变化之间存在显著关系。与体重正常/超重/肥胖的个体相比，体重不足的个体冬季 SBP/DBP 的平均升高幅度更大（P<.05）。与夏季相比，冬季 SBP/DBP 显著升高。在评估个体血压和比较社区研究时，应考虑这一季节性因素。
