During the summer of 1980, both swimmers and nonswimmers were enlisted in a prospective epidemiological study to determine the relationship between swimming, water quality, and the incidence of illness. Results of 4,537 telephone follow-up interviews showed that crude morbidity rates were 69.6 per 1,000 swimmers versus 29.5 per 1,000 nonswimmers. Swimmers experienced respiratory ailments most frequently, followed by gastrointestinal, eye, ear, skin, and allergenic symptoms, respectively.
1980年夏天,游泳者和非游泳者都参与了一项前瞻性流行病学研究,以确定游泳、水质与疾病发病率之间的关系。4537次电话随访访谈的结果显示,每1000名游泳者的粗发病率为69.6,而每1000名非游泳者为29.5。游泳者最常出现呼吸道疾病,其次分别是胃肠道、眼睛、耳朵、皮肤和过敏症状。
