目的有限的数据表明体力活动或健康水平与上呼吸道感染（URTI）的发生率呈负相关。本研究的目的是监测一组异质性社区成年人的URTI症状和严重程度，并在调整潜在混杂因素的同时，对身体活动和健身水平的三分位数进行对比。（年龄18-85岁，60%为女性，40%男性）在冬季和秋季随访12周，同时使用威斯康星州上呼吸道症状调查监测URTI症状和严重程度。受试者报告有氧运动的频率，并使用10分制李克特量表评定他们的身体健康水平。一个一般线性模型，调整了7个混杂因素，被用来检查运动频率和健身水平对URTI天数和症状严重程度的影响。结果在12周期间URTI天数显著减少，43%的受试者报告>= 5天/周的有氧运动，而那些主要是久坐不动的人（
Objective Limited data imply an inverse relationship between physical activity or fitness level and the rates of upper respiratory tract infection (URTI). The purpose of this study was to monitor URTI symptoms and severity in a heterogeneous group of community adults and contrast across tertiles of physical activity and fitness levels while adjusting for potential confounders.Design A group of 1002 adults (ages 18-85 years, 60% female, 40% male) were followed for 12 weeks during the winter and fall seasons while monitoring URTI symptoms and severity using the Wisconsin Upper Respiratory Symptom Survey. Subjects reported frequency of aerobic activity, and rated their physical fitness level using a 10-point Likert scale. A general linear model, with adjustment for seven confounders, was used to examine the effect of exercise frequency and fitness level on the number of days with URTI and severity of symptoms.Results The number of days with URTI during the 12-week period was significantly reduced, 43% in subjects reporting >= 5 days/week aerobic exercise compared to those who were largely sedentary (
