Title: [abstract] ANNUAL DIVING FATALITY RATES AMONG INSURED DAN MEMBERS.
Author: Denoble, PJ; Vaithyanathan, P; Vann, RD
Abstract: INTRODUCTION: Annual fatalities among recreational divers in the US and Canada have decreased from 147 in 1975 to 89 in 2002, but annual fatality rates cannot be estimated as the number of people who dive each year is unknown. This study computed fatality rates among insured members of the Divers Alert Network (DAN), a relatively well-defined sub-population of divers. METHODS: Age, gender, and death while diving were extracted in de-identified form from about 150,000 insured DAN members for each year from 2000-2006. We computed the annual fatality rates in deaths per 100,000 members and tested their association with age, gender, and calendar year by logistic regression (p<0.05). We also computed the ratio of fatality rates (relative risks) for divers <50 and ≥50 years for drowning, arterial gas embolism (AGE), and cardiac incidents, which are the three major categories of disabling injury associated with diving death. RESULTS: Annual fatality rates varied from 12-23 per 100,000 with no trends during the observed period. Rates increased from 5 per 100,000 in teenagers to 40 per 100,000 in divers over age of 65 (5.5 odds ratio (OR), 1.2–11.5 95%CL). The rate was 7.6 per 100,000 for females compared with 21.2 per 100,000 for males (2.8 OR, 1.9–4.5 95%CL), but the difference in rates diminished with age, and the rates were similar above 60. Comparing fatality rates in divers <50 and ≥50 years, relative risks were 2.5 (1.3-5.1 95%CL) for drowning, 3.9 (1.6-9.3) for AGE, and 12.9 (5-33.5) for cardiac incidents. CONCLUSIONS: The fatality rate for insured DAN members increased with age as does the fatality rate for the general population of non-divers. The relative risk with age was greatest for cardiac incidents suggesting that people with risk factors for cardiovascular disease should have a physical exam before diving.
