Objectives. The purpose of this study is to evaluate and describe the current problem of drowning in Alaska, measure changes in the rates since earlier studies have been done and compare occupational and non-occupational drowning characteristics. Study design. This is a descriptive observational study, using existing records obtained from several sources to describe and compare drowning victims and event characteristics. Methods. Drowning fatality data were collected from death certificates, law-enforcement reports and news articles. Descriptive statistics and risk ratios were calculated to compare levels of risk based on incident and victim characteristics. Results. During 2000-2006, 402 unintentional drowning deaths, 108 of them occupational, occurred in Alaska, with an average annual fatality rate of 8.9 deaths per 100,000 Alaskans. The victim population was 86% male and 44% Alaska Native; 40% drowned in the south-west region of Alaska. For non-occupational cases with alcohol use documented, 33% were associated with alcohol consumption, as were 78% of those involved with all-terrain vehicle crashes. Only 17% of non-occupational victims who drowned while boating wore a Personal Flotation Device (PFD). Conclusions. The drowning rate in Alaska during 2000-2006 was 8.9 drowning deaths per 100,000 population. This shows a decrease from the rate reported in a 1996 study, but several problems persist. Males and Alaska Natives had elevated risks for drowning. A substantial portion of fatalities were associated with alcohol consumption. PFD use remains low, and child drowning rates were unchanged from earlier studies. Increased data on water temperature and immersion time may help demonstrate the benefits of PFD use to those at risk. Social marketing efforts should be adapted for at-risk populations.
We compared rates of unintentional injury (UI) deaths (total and by injury category) among Alaska Native (AN) people to rates of U.S. White (USW) and Alaska White (AKW) populations during 2006–2015. The mortality data for AN and AKW populations were obtained from Alaska Bureau of Vital Statistics and USW mortality data were obtained from WISQARS, the Center for Disease Control and Prevention online injury data program. AN and AKW rates were age-adjusted to the U.S. 2000 Standard Population and rate ratios (RR) were calculated. AN people had higher age-adjusted total UI mortality than the USW (RR = 2.6) and AKW (RR = 2.3) populations. Poisoning was the leading cause of UI death among AN people (35.9 per 100,000), more than twice that of USW (RR = 2.9) and AKW (RR = 2.5). Even greater disparities were found between AN people and USW for: natural environment (RR = 20.7), transport-other land (RR = 12.4), and drowning/submersion (RR = 9.1). Rates of AN UI were markedly higher than rates for either USW or AKW. Identifying all the ways in which alcohol/drugs contribute to UI deaths would aid in prevention efforts. All transportation deaths should be integrated into one fatality rate to provide more consistent comparisons between groups.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
