When asked, a significant number of patients report having experienced night sweats. Those who do are more likely to report decreased physical health, mental health, and quality of life. In most cases the cause of night sweats is unknown. We therefore do not know how much to worry about patients with this symptom. The present study examined associations between night sweats and mortality.
We used logistic regression and proportional hazards analyses to investigate potential predictors of mortality, including night sweats reported at baseline, among 2 different cohorts of people older than 65 years of age (n = 682 and n = 852) who were followed for an average of 7.3 and 7.5 years, respectively.
Patients who reported night sweats were not more likely to die or to die sooner than those who did not report night sweats after controlling for age, sex, body mass index, education, and income. This held true as well for patients who reported more severe night sweats among the cohort in which the severity of night sweats was quantified.
Patients who report night sweats on a primary care health history questionnaire do not seem, on average, to be at increased risk for mortality.
当被问及夜间出汗时，相当数量的患者报告有此经历。有此经历的患者更可能报告身体和心理健康状况下降以及生活质量降低。在大多数情况下，夜间出汗的原因不明。因此，我们不知道应该对有此症状的患者有多少担忧。本研究检查了夜间出汗与死亡率之间的关联。
我们使用逻辑回归和比例风险分析来研究死亡率的潜在预测因素，包括在两个年龄大于 65 岁的队列中（n=682 和 n=852）在基线时报告的夜间出汗，分别随访平均 7.3 年和 7.5 年。
在控制年龄、性别、体重指数、教育程度和收入后，报告有夜间出汗的患者并不比没有报告夜间出汗的患者更有可能死亡或更早死亡。在对夜间出汗严重程度进行量化的队列中，报告夜间出汗更严重的患者也是如此。
在初级保健健康史调查问卷中报告夜间出汗的患者平均而言似乎没有增加死亡风险。
