The purpose of the study is to evaluate the efficacy of gargling in treating colds which were self-reported by subjects. Workers in a foundry affiliated with a motor corporation were subject to monthly questionnaire surveys from January to March, 1994. They were assigned to the intervention group or to the non-intervention group as controls. The subjects in the intervention group were guided but not enforced to gargle with a remote foot pedal-operated gargling apparatus 3 times during daily work over a 3-month period. Statistical analysis of all data from questionnaires was done by chi-square test or Fisher's exact probability test with 2 x 2 (partially m x 1) correlation tables. The occurrence rate for colds based on the self-reported questionnaire was significantly lower in the intervention group with the significantly higher gargling compliance rate than in the non-intervention group throughout the study period. The rate of sick leave in the intervention group, as well as that of medication, also tended to be lower than in the control group. The results presented suggest that the rate of gargling compliance will be an important factor in the prevention of colds and in health care in a collective such as a workshop or a school.
本研究的目的是评估漱口疗法对受试者自我报告的感冒的治疗效果。一家汽车公司下属铸造厂的工人在1994年1月至3月期间每月接受问卷调查。他们被分为干预组或作为对照组的非干预组。干预组的受试者在为期3个月的日常工作中，被指导（但非强制）使用遥控脚踏式漱口装置漱口3次。对问卷中的所有数据进行统计分析时，采用卡方检验或费舍尔精确概率检验，并使用2×2（部分为m×1）关联表。在整个研究期间，基于自我报告问卷的感冒发生率在干预组显著低于非干预组，且干预组的漱口依从率显著更高。干预组的病假率以及用药率也往往低于对照组。研究结果表明，漱口依从率将是预防感冒以及在车间或学校等集体场所进行医疗保健的一个重要因素。
