Acute respiratory tract infection (ARI) was investigated in children less than 5 years old in a longitudinal community-based study of 166 families living in a socioeconomically depressed area in Montevideo, Uruguay. Pediatricians made home visits every 10 days from May 1985 to December 1987, and symptoms and signs of ARI were recorded. The incidence of ARI was 5.8 episodes per child-year during the first 12 months of life and decreased with increasing age of the index children; the rate was highest in children 1-5 months old. Children observed from birth were ill during 21% of the visits. According to the definitions of the study, the incidence of lower respiratory tract infection was 11.6% higher than the incidence of upper respiratory tract infections. The rates of ARI were higher during the colder months. Most risk factors for ARI were only marginally statistically significant.
在乌拉圭蒙得维的亚一个社会经济状况不佳地区，对166个家庭中5岁以下儿童进行了一项基于社区的纵向研究，调查急性呼吸道感染（ARI）情况。从1985年5月至1987年12月，儿科医生每10天进行一次家访，并记录ARI的症状和体征。在生命的前12个月中，ARI的发病率为每名儿童每年5.8次发作，且随着索引儿童年龄的增长而降低；发病率在1 - 5个月大的儿童中最高。从出生就开始观察的儿童在21%的家访期间患病。根据该研究的定义，下呼吸道感染的发病率比上呼吸道感染的发病率高11.6%。ARI的发病率在较寒冷的月份更高。ARI的大多数风险因素在统计学上仅具有微弱的显著性。
