The aim was to determine the incidence of symptoms of decompression sickness (DCS) in dive masters and instructors in relation to number of dives and possible risk factors.
Retrospective cohort study of dive masters and instructors in Sweden. STUDY BASE: All dive masters and instructors listed with PADI, NAUI and CMAS in Sweden as of January 1st 1999 (2380 divers).
The dive masters and instructors received a validated questionnaire on diving activities and symptoms of DCS in 1999. 1516 men and 226 women answered, i.e. 73% of the initial study base.
DCS symptoms were reported by 190 divers. The incidence of DCS symptoms was 1.52 for males and 1.27 for females per 1000 dives. Dive masters, divers not performing decompression-stop dives, divers not practicing advanced diving and divers with a low number of total lifetime dives had a higher proportion (p < 0.05) of DCS symptoms per 1000 dives. There were no major differences in DCS symptom incidence related to sex, age, asthma, overweight or alcohol abuse in this study.
目的是确定潜水长和教练中减压病（DCS）症状的发生率与潜水次数及可能的风险因素之间的关系。
对瑞典潜水长和教练进行回顾性队列研究。研究基础：截至1999年1月1日在瑞典PADI、NAUI和CMAS登记的所有潜水长和教练（2380名潜水员）。
1999年，潜水长和教练收到一份关于潜水活动和DCS症状的有效问卷。1516名男性和226名女性作答，即占初始研究基础的73%。
190名潜水员报告有DCS症状。男性每1000次潜水的DCS症状发生率为1.52，女性为1.27。潜水长、未进行减压停留潜水的潜水员、未进行高级潜水训练的潜水员以及终生潜水次数较少的潜水员，每1000次潜水出现DCS症状的比例更高（p<0.05）。本研究中，DCS症状发生率在性别、年龄、哮喘、超重或酗酒方面无显著差异。
