1.目的：1.探讨影响血压正常妇女家庭血压季节性变化的因素. 16名女性受试者（56.3 ± 7.9岁，平均值± SD）在至少1.5年的时间里，每月在家中每天早晨测量血压和脉率超过20次，在此期间，每月在办公室测量血压和体重一次或两次，室外和室内温度以及白天长度的月平均值来自气象台。采用单余弦法评价年周期节律.我们观察到在家中测量的自记血压、环境温度和白天长度的双相季节性变化，但发现体重和办公室测量的血压没有明显的季节性变化，在家中测量的收缩压和舒张压在7月最低，在6月记录的白天长度最长，而室外温度和室内温度最高值均出现在8月，表明最长白昼时间先于最低血压，最高环境温度滞后于最低血压。白天最短的是12月，室外和室内温度最低的是1月，收缩压和舒张压最高的分别是1月和12月。自我记录的收缩压和舒张压的半幅值分别为2.6 ± 1.0 mmHg和2.0 ± 0.8 mmHg。这些发现表明季节性影响的重要性，即白天的长度和环境温度，对个人的情绪压力。
1. The factors influencing the seasonal variation in blood pressure measured at home in normotensive women were examined.2. Sixteen female subjects (56.3 +/- 7.9 years old, mean +/- SD) measured their blood pressure and pulse rate at home each morning for more than 20 times per month for at least 1.5 years, Blood pressure and body weight were also determined in the office once or twice a month in that period, Monthly means of outdoor and indoor temperatures and daytime length were obtained from the Meteorological Observatory. The single cosinor method was used to evaluate circannual rhythm.3. We observed a biphasic seasonal variation in self-recorded blood pressure measured at home, environmental temperature and daytime length but found no apparent seasonal variation in body weight and blood pressure measured in the office, The lowest levels of systolic and diastolic blood pressure measured at home were observed in July, The longest daytime length was recorded in June, while the highest outdoor temperature and indoor temperature were recorded in August, indicating that the longest daytime length preceded and the highest environmental temperature lagged behind the lowest level of blood pressure. The shortest daytime length is in December, The lowest outdoor and indoor temperature were observed in January, while the highest levels of self-recorded systolic blood pressure and diastolic blood pressure were in January and December, respectively. Half-amplitudes of self-recorded systolic and diastolic blood pressure were 2.6 +/- 1.0 mmHg and 2.0 +/- 0.8 mmHg, respectively.4. These findings indicate the importance of a seasonal effect, i.e. daytime length and the environmental temperature, on the Mood pressure of individuals.
