The aim of this study was to compare, by stratification, subgroups of hairdressers. Three groups were considered: Group I (102 persons) consisted of hairdressers reporting skin affection at the time of completing an earlier mailed questionnaire (point prevalence). Group II reported exanthema prior to completing, while group III reported not having had exanthema at all (51 and 50 persons, respectively). No significant difference was found between these groups with regard to age and duration in work. The mean number of months since start of disease was significantly higher for group I (64 (range: 0.5-552)) than group II (7 (range: 0.6-38)). The frequency of atopic dermatitis was 12.7% (C.I: 6.3-19.2) in group I, compared with 3.9% (C.I: 0.0-9.2) in group II and none in group III. This difference between groups was significant. A significantly higher extent of sick leave was found in group I, compared to group II.
本研究的目的是通过分层比较美发师的亚组。研究考虑了三组：第一组（102人）由在完成之前邮寄的问卷时报告有皮肤问题的美发师组成（现患率）。第二组在完成问卷之前报告有皮疹，而第三组报告根本没有皮疹（分别为51人和50人）。这些组在年龄和工作年限方面没有发现显著差异。自疾病开始以来的平均月数，第一组（64（范围：0.5 - 552））显著高于第二组（7（范围：0.6 - 38））。第一组特应性皮炎的发生率为12.7%（置信区间：6.3 - 19.2），相比之下，第二组为3.9%（置信区间：0.0 - 9.2），第三组为零。组间差异显著！与第二组相比，第一组的病假天数显著更高。
