目标。评估头痛患者对天气如何强烈影响他们头痛的信念;客观地调查多种天气变量对头痛的影响。我们的样本包括77名在头痛诊所就诊的偏头痛患者，他们提供了2至24个月的头痛日历。我们的研究分为两个阶段。首先，每位患者都收到了一份问卷，评估他们对天气影响头痛的程度（如果是这样的话）的看法。其次，天气数据是从国家气象局收集的，来自研究参与者住所中心的三个报告站。对43个变量进行分析，产生三个气象因素。采用线性回归分析这三个因素与头痛的关系。系数1表示绝对温度和湿度的函数。因子2表示变化的天气模式。系数3代表大气压力。在77名被试中，有39人（50.6%）对天气敏感，而48人（62.3%）认为自己对天气条件敏感（P < 0.05）。30例（38.9%）对一种气象因子敏感，9例（11.7%）对两种气象因子敏感。26人（33.7%）对因素1敏感; 11人（14.3%）对因素2敏感; 10人（12.9%）对因素3敏感。结论。我们的研究支持天气变量对头痛的影响。我们发现，患者容易受到多种天气变量的影响，更多的患者认为天气是一个触发因素。
Objectives.-To assess headache patients' beliefs about how strongly weather affects their headaches; To objectively investigate the influence of multiple weather variables on headache.Design and Methods.-Our sample consisted of 77 migraineurs seen in a headache clinic, who provided headache calendars for a period ranging from 2 to 24 months. Our study was divided into two phases. First, each patient was given a questionnaire assessing their beliefs about how strongly (if so) weather affected their headaches. Second, weather data were collected from the National Weather Service, from three reporting stations central to the residences of the study participants. Analysis was performed on 43 variables to generate three meteorological factors. Linear regression was used to assess the relationship between headache and these three factors. Factor 1 represents a function of absolute temperature and humidity. Factor 2 represents a changing weather pattern. Factor 3 represents barometric pressure.Results.-Of the 77 subjects in the study, 39 (50.6%), were found to be sensitive to weather, but 48 (62.3%) thought they were sensitive to weather conditions (P < 0.05). Thirty (38.9%) were sensitive to one weather factor and 9 (11.7%) to two factors. Twenty-six (33.7%) were sensitive to factor 1; 11 (14.3%) to factor 2; 10 (12.9%) to factor 3.Conclusions.-Our study supports the influence of weather variables on headache. We showed that patients are susceptible to multiple weather variables and that more patients thought weather was a trigger than was the case.
