Persistent Racial/Ethnic Disparities in Fatal Unintentional Drowning Rates Among Persons Aged ≤29 Years - United States, 1999-2019.

During 1999-2019, a total of 81,947 unintentional drowning deaths occurred in the United States (1). Drowning is one of the three leading causes of unintentional injury death among persons aged ≤29 years and results in more deaths among children aged 1-4 years than any other cause except birth defects (2). Drowning death rates have decreased since 1990 (declining by 57% worldwide and by 32% in the United States) (3). However, because of racial/ethnic disparities in drowning risk, rates remain high among certain racial/ethnic groups, particularly American Indian or Alaska Native (AI/AN) persons and Black or African-American (Black) persons (4). To assess whether decreasing drowning death rates have been accompanied by reductions in racial/ethnic disparities, and to further describe these disparities by age group and setting, CDC analyzed U.S. mortality data during 1999-2019. The drowning death rate among persons aged ≤29 years was 1.3 per 100,000 population. The rate per 100,000 among AI/AN persons (2.5) and Black persons (1.8) was higher than among all other racial/ethnic groups and was 2.0 and 1.5 times higher than among White persons (1.2). Racial/ethnic disparities in drowning death rates did not significantly decline for most groups, and the disparity in rates among Black persons compared with White persons increased significantly from 2005-2019. Drowning death rates are associated with persistent and concerning racial/ethnic disparities. A better understanding of the factors that contribute to drowning disparities is needed. Implementing and evaluating community-based interventions, including those promoting basic swimming and water safety skills, among disproportionately affected racial/ethnic groups could help reduce drowning disparities.

Vanishing racial disparities in drowning in Florida.

OBJECTIVES: To examine the change in the racial disparity in drowning in Florida from 1970 to 2015 and to analyse the contextual factors associated with white, black and Hispanic drowning rates in Florida from 2007 to 2015. METHODS: Our outcome variable is county-level annual drowning rates by race, ethnicity, sex and age group. We computed county-level contextual data, including emergency weather events, temperature, extreme weather, number of pools, quality of pools, coastline, swimming participation rates and prominent black competitive swim teams. RESULTS: Between 1970 and 1990, the disparity in drowning rates between white and black males in Florida decreased dramatically. By 2005, the overall age-adjusted drowning rates converged. This convergence was most striking for those aged 10-34 and 35-64. While the gap has declined dramatically, there remains a racial disparity in drownings among those aged 10-34. CONCLUSIONS: Overall, racial disparities in drowning have disappeared in Florida. However, some disparities remain. There is a persistent disparity in drownings among those aged 10-34.

Disproportionately higher unintentional injury mortality among Alaska Native people, 2006-2015.

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.

Ethnic Differences in Drowning Rates in Ontario, Canada.

The scientific literature suggests ethnicity may be a risk factor for drowning. Ontario, Canada is one of the most ethnically diverse places in the world. The objective of our study was to determine if Asians, Africans and Hispanics were at an increased risk of drowning compared to Greater Europeans. Ethnicity served as a surrogate for country of origin. Using Coroner's reports, all unintentional drowning deaths in Ontario from 2004 to 2008 were reviewed. The ethnicity of drowning victims was estimated using a previously validated name-based ethnicity classifier. Age-standardized drowning rates were calculated by sex and place of residence (rural vs. non-rural) for people of each ethnicity group using the method of direct standardization. For residents of Ontario living in rural areas, the age-standardized drowning rate was significantly higher among men of Asian, African, or Hispanic ethnicity compared to men of Greater European ethnicity (RR 13.9; 95% CI 8.1-23.8) and for women of Asian, African, or Hispanic ethnicity compared to women of Greater European ethnicity (RR 23.9; 95% CI 6.4-89.1). These high-risk individuals need to be considered when developing drowning prevention strategies.

Racial and ethnic disparities in fatal unintentional drowning among persons less than 30 years of age--United States, 1999-2010.

BACKGROUND: In the U.S., almost 4,000 persons die from drowning annually. Among those 0-29 years, drowning is in the top three causes of unintentional injury death. METHODS: To describe racial/ethnic differences in drowning rates by age of decedent and drowning setting, CDC analyzed 12 years of mortality data from 1999 through 2010 for those ≤29 years. RESULTS: Compared to whites, American Indians/Alaska Natives were twice, and blacks were 1.4 times, as likely to drown. Disparities were greatest in swimming pool settings, with drowning rates among blacks aged 5-19 years 5.5 times higher than those among whites. CONCLUSIONS: Drowning rates for black children and teens are higher than those of other race/ethnicities, especially in swimming pools. PRACTICAL APPLICATION: The practicality and effectiveness of current drowning prevention strategies varies by setting; however, basic swimming skills can be beneficial across all settings and may help reduce racial disparities.

Racial/ethnic disparities in fatal unintentional drowning among persons aged ≤ 29 years - United States, 1999-2010.

In the United States, almost 4,000 persons die from drowning each year. Drowning is responsible for more deaths among children aged 1-4 years than any other cause except congenital anomalies. For persons aged ≤29 years, drowning is one of the top three causes of unintentional injury death (2). Previous research has identified racial/ethnic disparities in drowning rates. To describe these differences by age of decedent and drowning setting, CDC analyzed 12 years of combined mortality data from 1999-2010 for those aged ≤29 years. Among non-Hispanics, the overall drowning rate for American Indians/Alaska Natives (AI/AN) was twice the rate for whites, and the rate for blacks was 1.4 times the rate for whites. Disparities were greatest in swimming pools, with swimming pool drowning rates among blacks aged 5-19 years 5.5 times higher than those among whites in the same age group. This disparity was greatest at ages 11-12 years; at these ages, blacks drown in swimming pools at 10 times the rate of whites. Drowning prevention strategies include using barriers (e.g., fencing) and life jackets, actively supervising or lifeguarding, teaching basic swimming skills and performing bystander cardiopulmonary resuscitation (CPR). The practicality and effectiveness of these strategies varies by setting; however, basic swimming skills can be beneficial across all settings.

Hospitalizations for unintentional injuries among Canadian adults in areas with a high percentage of Aboriginal-identity residents.

INTRODUCTION: Injuries are a leading cause of death and morbidity. While individual Aboriginal identifiers are not routinely available on national administrative databases, this study examines unintentional injury hospitalization, by cause, in areas with a high percentage of Aboriginal-identity residents. METHODS: Age-standardized hospitalization rates (ASHRs) and rate ratios were calculated based on 2004/2005-2009/2010 data from the Discharge Abstract Database. RESULTS: Falls were the most frequent cause of injury. For both sexes, ASHRs were highest in high-percentage First Nations-identity areas; high-percentage Métis-identity areas presented the highest overall ASHR among men aged 20-29 years, and high-percentage Inuit-identity areas presented the lowest ASHRs among men of all age groups. Some causes, such as falls, presented a high ASHR but a rate ratio similar to that for all causes combined; other causes, such as firearm injuries among men in high-percentage First Nations-identity areas, presented a relatively low ASHR but a high rate ratio. Residents of high-percentage Aboriginal-identity areas have a higher ASHR for hospitalization for injuries than residents of low-percentage Aboriginal-identity areas. CONCLUSION: Residents of high-percentage Aboriginal-identity areas also live in areas of lower socio-economic conditions, suggesting that the causes for rate differences among areas require further investigation.

TITRE: Hospitalisations pour blessures non intentionnelles chez les adultes au Canada, dans les régions ayant un fort pourcentage de résidents d'identité autochtone. INTRODUCTION: Les blessures constituent une cause importante de décès et de morbidité. Bien qu'aucun indicateur d'identité autochtone ne soit directement disponible dans les bases de données administratives nationales, cette étude porte sur les hospitalisations pour blessure non intentionnelle, selon la cause, dans les régions ayant un fort pourcentage de résidents d'identité autochtone. MÉTHODOLOGIE: Nous avons calculé les taux d'hospitalisation normalisés selon l'âge (THNA) et les rapports de taux pour 2004-2005 à 2009-2010, à partir de la Base de données sur les congés des patients. RÉSULTATS: Les chutes étaient la cause principale de blessure. Les THNA étaient plus élevés pour les hommes comme pour les femmes dans les régions ayant un fort pourcentage de membres des Premières nations; dans les régions ayant un fort pourcentage de Métis, c'est chez les hommes de 20 à 29 ans que le THNA global était le plus élevé, tandis qu'il était le plus bas chez les hommes de tous les groupes d'âge dans les régions à fort pourcentage d'Inuits. Certaines causes, telles que les chutes, étaient associées à un THNA élevé mais avec un rapport de taux semblable à celui observé pour toutes causes confondues; d'autres causes, comme les blessures par arme à feu chez les hommes dans les régions à fort pourcentage de membres des Premières nations, présentaient un THNA relativement faible mais un rapport de taux élevé. Les résidents des régions à fort pourcentage d'Autochtones présentaient un THNA pour blessure plus élevé que ceux des régions à faible pourcentage d'Autochtones. CONCLUSION: Les résidents des régions à fort pourcentage d'Autochtones vivent dans des régions dont le statut socioéconomique était faible, ce qui invite à une recherche plus approfondie à propos des différences de taux entre régions.

Characteristics of syncope in Japan and the Pacific rim.

As is true in the Western world, syncope of cardiac and non-cardiac origin is one of the common clinical presentations in daily medical practice in Japan and Asia. However, the underlying disorders and social backgrounds associated with syncope may differ, from those encountered in Western countries, particularly in Japan. While non-cardiac causes, neurally-mediated reflex faints in particular, are highly prevalent, out-of-hospital deaths by drowning due to syncope occurring during bathing at home are not rare in Japan, particularly in the elderly. Other underlying cardiac or non-cardiac disorders are also noteworthy, particularly Brugada syndrome and coronary vasospasm, which may present as isolated syncope. In addition, the characteristic clinical presentation of micturition and defecation syncope is not uncommon. This review is focused on these specific underlying diseases in the light of the guidelines issued by the Japanese Circulation Society regarding the diagnosis and treatment of syncope.

The legacy of fear: is fear impacting fatal and non-fatal drowning of African American children?

African American children's rates for fatal and non-fatal drowning events are alarmingly elevated, with some age groups having three times the rate as compared to White peers. Adequate swimming skills are considered a protective agent toward the prevention of drowning, but marginalized youth report limited swimming ability. This research examined minority children's and parents/caregivers' fear of drowning as a possible variable associated with limited swimming ability. Results confirmed that there were significant racial differences concerning the fear of drowning, and adolescent African American females were notably more likely to fear drowning while swimming than any other group. The "fear of drowning" responses by parents/ caregivers of minority children were also significantly different from their White counterparts.

Urban minority youth swimming (in)ability in the United States and associated demographic characteristics: toward a drowning prevention plan.

OBJECTIVE: To examine swimming ability and variables associated with swimming for US inner-city, minority children. Empirical research on minority children's swimming ability is non-existent, and drowning rates for this population are high. DESIGN: Cross-sectional survey research. Descriptive statistics were produced. Multiple regression was applied using significant demographic variables by swimming ability. SETTING: Six US cities were chosen (Chicago, Illinois; Houston, Texas; Memphis, Tennessee; Miami, Florida; Oakland, California; Philadelphia, Pennsylvania). Young Men's Christian Association (YMCA) facilities were used to solicit subjects. SUBJECTS: A large sample (n = 1680) was gathered, which targeted poor, minority children. Parents of children aged 4-11 years and adolescents (12-17 years) completed surveys that research team members or trained YMCA staff supervised during non-swimming YMCA programmes. RESULTS: African-American respondents reported a 57.5% "at risk" (unable to swim or uncomfortable in deep end of pool) swimming ability. Hispanic/Latino children confirmed a 56.2% "at risk" level as compared with 30.9% for white subjects. Age, sex, child's lunch programme, parental education and race variables were all significantly (p<0.05) related to swimming ability. Regression analysis revealed that all demographic variables fell into a significant model (p<0.001) as predictor variables. CONCLUSIONS: Poor minority children, specifically African-American and Hispanic/Latino, are at a significant disadvantage concerning swimming ability. Female subjects were notably more "at risk" regarding their swimming ability than male subjects. Age, race and socioeconomic factors (lunch programme and parental education) were significantly associated with children who have low swimming ability.

[Reduction of the drowning risk for young children, but increased risk for children of recently immigrated non-Westerners]. / Afname van het verdrinkingsrisico bij jonge kinderen, maar verhoogd risico bij kinderen van recent geïmmigreerde niet-westerse allochtonen.

OBJECTIVE: To describe differences in the risk of drowning of young children (under 10 years) in the Netherlands according to ethnicity and relevant trends since 996. DESIGN: Retrospective. METHOD: We analysed the causes of death data for all 266 children aged 0 to 10 years who died of drowning between 1996 and 2005. Information for the cause of death was obtained from the cause of death data of Statistics Netherlands. Data about the size and composition of the population at risk (age, sex and ethnicity) were obtained from the municipal population registers. RESULTS: Young children's risk of drowning has decreased by about one-third since 1996. This decrease took place among native Dutch children and children of the major ethnic groups, notably Turkish, Moroccan and Surinamese. However for children of recently immigrated parents of non-Western ethnicity, mainly asylum seekers, the risk of drowning was 4 to 8 times higher than that of native children aged 3 to 10 years. CONCLUSION: Timely health education directed at newly arrived families with children could be an important measure to help them cope with the hazards of living in a water-rich environment such as the Netherlands. The education should point out the necessity of increased supervision of the youngest children and improved swimming skills for the slightly older ones.

Beliefs and practices to prevent drowning among Vietnamese-American adolescents and parents.

OBJECTIVE: To determine the beliefs, attitudes and practices regarding water safety among Vietnamese-Americans through focus group interviews. PARTICIPANTS: 15 teenagers (aged 15-19 years) and 20 parents participated, and reported similar attitudes, beliefs and practices regarding water activities. Participants identified a lack of familiarity with water activities and few swimming skills, noting that these activities are not perceived as recreational sports among the Vietnamese. They reported recreating at open water sites because they are free and available, and attributed drowning to fate. Vietnamese youth swim unsupervised, responding to peer pressure despite lack of skills. Participants had negative attitudes toward life jackets using, swimming pools and lessons, because of the costs, but would attend lessons in Vietnamese. They identified schools and Vietnamese media as means of delivering injury-prevention messages. CONCLUSIONS: Decreasing drowning among Vietnamese-Americans requires changing the knowledge, attitudes and safety practices with programs and messages in Vietnamese, as well as targeting the dominant culture.

Swimming pool drownings among US residents aged 5-24 years: understanding racial/ethnic disparities.

OBJECTIVE: We examined circumstances surrounding swimming pool drownings among US residents aged 5 to 24 years to understand why Black males and other racial/ethnic groups have high drowning rates. METHODS: We obtained data about drowning deaths in the United States (1995-1998) from death certificates, medical examiner reports, and newspaper clippings collected by the US Consumer Product Safety Commission. RESULTS: During the study period, 678 US residents aged 5 to 24 years drowned in pools. Seventy-five percent were male, 47% were Black, 33% were White, and 12% were Hispanic. Drowning rates were highest among Black males, and this increased risk persisted after we controlled for income. The majority of Black victims (51%) drowned in public pools, the majority of White victims (55%) drowned in residential pools, and the majority of Hispanic victims (35%) drowned in neighborhood pools (e.g., an apartment complex pool). Foreign-born males also had an increased risk for drowning compared with American-born males. CONCLUSIONS: Targeted interventions are needed to reduce the incidence of swimming pool drownings across racial/ethnic groups, particularly adult supervision at public pools.

Prevention of drowning in infants, children, and adolescents.

Drowning is a leading cause of injury-related death in children. In 2000, more than 1400 US children younger than 20 years drowned. Most (91%) of these deaths were unintentional and were not related to boating. For each drowning death, it is estimated that at least 1 to 4 children suffer a serious nonfatal submersion event, many of which leave children with permanent disabilities. Environmental strategies, such as installation of 4-sided fences around swimming pools, and behavioral strategies, such as increased supervision of children while around water, are needed to prevent these tragedies.

Evidence for an early onset of endogenous alcohol production in bodies recovered from the water: implications for studying alcohol and drowning.

Endogenous alcohol production can increase the blood alcohol concentration (BAC) of drowning victims following submersion and confound epidemiological studies of the role of alcohol. This study seeks to determine how soon after a drowning death a victim's BAC is influenced by post-mortem alcohol production. The drop in mean lung weight that occurs over time in the water was hypothesized to serve as a proxy for the time course of decomposition, and thus provide an empirical measure to determine how soon after death to first suspect endogenous alcohol. The autopsy lung weights of 562 previously healthy males who drowned were compared across six submersion time groups (0-11.9, 12-23.9, 24-47.9, 48-95.9, 96-167.9 and >or=168 h) and two times of year (winter and non-winter). The hypothesis that a drop in lung weight is sensitive to the time course of decomposition was supported by (1). a statistically significant drop in mean lung weight that occurred 12-23.9 h post-submersion in the non-winter months, but not until 96-167.9 h in the colder winter months; and (2). a significant drop in lung weight was not observed in the group of cases with zero BAC. With a parallel finding that an increase in the proportion of cases with a positive BAC first occurred at the 12-23.9 h submersion group during the warmer non-winter months, we concluded that production of alcohol can occur in bodies recovered from the water as early as 12 h after death. Because excluding drownings with submersion durations greater than 12 h would exclude almost half of our cases from epidemiological studies of alcohol and drowning, additional evidence from the forensic literature was used to develop an adjustment procedure to account for endogenous alcohol production for submersion times of up to 1 week.

Where children drown, United States, 1995.

CONTEXT: Drowning is the second leading cause of unintentional injury death among children ages 1 to 19 years. Details about the specific site of submersion are important for implementation of primary prevention efforts, but are not routinely available from national data. OBJECTIVES: To provide national data about the specific sites of drowning among US children and to examine site-specific drowning rates by age, race, and gender. SETTING: United States, 1995. DESIGN: Information was abstracted from death certificates for unintentional drownings among children <20 years of age. The site of drowning was coded from free text on death certificates. Proportional distributions of the site of drowning by age, region, gender, and race were examined. Site-specific drowning rates were calculated by age, race, and gender. Denominators were based on US Census Bureau, June 1995 estimates of the US population. RESULTS: For 1995, death certificates were obtained for 1420 unintentional drownings among children <20 years of age, 98% of the number of drowning deaths reported by the National Center for Health Statistics for the same year. Site of drowning was specified on 1308 (92%) death certificates. Fifty-five percent of infant drownings were in bathtubs. Among children between the ages of 1 to 4 years, 56% of drownings were in artificial pools and 26% were in other bodies of freshwater. Among older children, 63% of drownings were in natural bodies of freshwater. Site-specific drowning rates varied by race. Importantly, after the age of 5 years, the risk of drowning in a swimming pool was greater among black males compared with white males with rate ratios of 15.1 (95% confidence interval: 6.7-38.5) among 10- to 14-year-olds and 12.8 (95% confidence interval: 6.5-26.9) among 15- to 19-year-olds. CONCLUSION: The variety of sites in which children drown, even within specific age groups, emphasizes the need for a multifaceted approach to prevention. Reductions in the relatively high rates of drowning among black adolescent males will require targeted interventions to prevent swimming pool drownings among this group.
