RESUMO
Introduction: Drowning is the cause of approximately 4,000 U.S. deaths each year and disproportionately affects some age, racial, and ethnic groups. Infrastructure disruptions during the COVID-19 pandemic, including limited access to supervised swimming settings, might have affected drowning rates and risk. Data on factors that contribute to drowning risk are limited. To assess the potential impact of the pandemic on drowning death rates, pre- and post-COVID-19 pandemic rates were compared. Methods: National Vital Statistics System data were used to compare unintentional drowning death rates in 2019 (pre-COVID-19 pandemic onset) with those in 2020, 2021, and 2022 (post-pandemic onset) by age, sex, and race and ethnicity. National probability-based online panel survey (National Center for Health Statistics Rapid Surveys System) data from October-November 2023 were used to describe adults' self-reported swimming skill, swimming lesson participation, and exposure to recreational water. Results: Unintentional drowning death rates were significantly higher during 2020, 2021, and 2022 compared with those in 2019. In all years, rates were highest among children aged 1-4 years; significant increases occurred in most age groups. The highest drowning rates were among non-Hispanic American Indian or Alaska Native and non-Hispanic Black or African American persons. Approximately one half (54.7%) of U.S. adults reported never having taken a swimming lesson. Swimming skill and swimming lesson participation differed by age, sex, and race and ethnicity. Conclusions and Implications for Public Health Practice: Recent increases in drowning rates, including those among populations already at high risk, have increased the urgency of implementing prevention strategies. Basic swimming and water safety skills training can reduce the risk for drowning. Addressing social and structural barriers that limit access to this training might reduce drowning deaths and inequities. The U.S. National Water Safety Action Plan provides recommendations and tools for communities and organizations to enhance basic swimming and water safety skills training.

OBJECTIVES: To improve national drowning surveillance efforts, we developed and evaluated a definition for unintentional drowning for use in the National Syndromic Surveillance Program's ESSENCE platform (Electronic Surveillance System for the Early Notification of Community-Based Epidemics) and described drowning-related emergency department (ED) visits from 2019 through 2022 using the new definition. METHODS: We adapted an unintentional drowning definition from a previous version, which included all drowning-related ED visits regardless of intent (including drowning related to assault and suicide, as well as unintentional drowning). We reviewed a random sample of 1000 visits captured by the new definition of unintentional drowning and categorized visits as likely, possibly, and unlikely to be related to unintentional drowning. We compared monthly drowning-related ED visits from 2020, 2021, and 2022 with monthly drowning ED visits from 2019, overall and by sex and age group. RESULTS: A total of 35 431 ED visits related to unintentional drowning (10.71 per 100 000 ED visits) occurred from 2019 through 2022. Most visits (86%) captured by the new definition and manually reviewed were likely related to unintentional drowning. Rates were highest among males (14.04 per 100 000 ED visits) and children aged <1 to 4 years (65.61 per 100 000 ED visits). The number of drowning-related ED visits was higher in May and August 2020, May and June 2021, and May 2022 as compared with the same months in 2019 among people aged 18 to 44 years. CONCLUSIONS: The definition for unintentional drowning is available in the National Syndromic Surveillance Program's ESSENCE platform for state and local jurisdictions to use to monitor unintentional drowning-related ED visits in near-real time to inform prevention strategies.
RESUMO
INTRODUCTION: During the COVID-19 pandemic, one study in Australia showed an increase in drowning deaths in certain settings, while a study in China showed a decrease in drowning deaths. The impact of the COVID-19 pandemic on drowning deaths in the United States is unknown. OBJECTIVE: To report on unintentional drowning deaths among U.S. persons aged ≤29â¯years by demographic characteristics and compare 2020 fatal drowning rates with rates from 2010 to 2019. METHODS: Data from CDC WONDER were analyzed to calculate unintentional drowning death rates among persons aged ≤29â¯years by age group, sex, race/ethnicity, and location of drowning. These rates were compared to drowning death rates for the previous 10â¯years (2010-2019). RESULTS: In 2020, 1.26 per 100,000 persons aged ≤29â¯years died from unintentional drowning, a 16.79% increase from 2019. Drowning death rates decreased 1.81% per year on average (95% CI: -3.02%, -0.59%) from 2010 to 2019. The largest increases in unintentional drowning deaths from 2019 to 2020 occurred among young adults aged 20 to 24â¯years (44.12%), Black or African American persons (23.73%), and males (19.55%). The location with the largest increase in drowning was natural water (26.44%). CONCLUSION: Drowning death rates among persons aged ≤29â¯years significantly increased from 2019 to 2020. Further research is needed to understand the impacts of the COVID-19 pandemic on drowning and identify how drowning prevention strategies can be adapted and strengthened. PRACTICAL APPLICATIONS: Drowning remains a leading cause of injury death among persons aged ≤29â¯years. However, drowning is preventable. Interventions such as learning basic swimming and water safety skills, and consistent use of lifejackets on boats and among weaker swimmers in natural water, have the potential to reduce drowning deaths. Developing strategies that ensure equitable access to these interventions may prevent future drowning.

BACKGROUND: Drowning accounts for hundreds of preventable deaths in Canada every year, but the impact of preexisting medical conditions on the likelihood of death from drowning is not known. We aimed to describe the prevalence of pre-existing medical conditions among people who fatally drowned in Canada and evaluate the risk of fatal drowning among people with common pre-existing medical conditions. METHODS: We reviewed all Canadian unintentional fatal drownings (2007-2016) in the Drowning Prevention Research Centre Canada's database. For each fatal drowning we established whether the person had pre-existing medical conditions and whether those conditions contributed to the drowning. We calculated relative risk (RR) of fatal drowning stratified by age and sex for each pre-existing medical condition using data from the Canadian Chronic Disease Surveillance System. RESULTS: During 2007-2016, 4288 people fatally drowned unintentially in Canada, of whom one-third had a pre-existing medical condition. A pre-existing medical condition contributed to drowning in 43.6% (n = 616) of cases. Fatal drowning occurred more frequently in people with ischemic heart disease (RR 2.7, 95% confidence interval [CI] 2.5-3.0) and seizure disorders (RR 6.3, 95% CI 5.4-7.3) but less frequently in people with respiratory disease (RR 0.12, 95% CI 0.10-0.15). Females aged 20-34 years with a seizure disorder had a 23 times greater risk than their age- and sex-matched cohort (RR 23, 95% CI 14-39). In general, fatal drowning occurred more often while people were bathing (RR 5.9, 95% CI 4.8-7.0) or alone (RR 1.99, 95% CI 1.32-2.97) and less often in males (RR 0.92, 95% CI 0.88-0.95) or in those who had used alcohol (RR 0.72, 95% CI 0.65-0.80), among those with pre-existing medical conditions. INTERPRETATION: The risk of fatal drowning is increased in the presence of some preexisting medical conditions. Tailored interventions aimed at preventing drowning based on pre-existing medical conditions and age are needed. Initial prevention strategies should focus on seizure disorders and bathtub drownings.

BACKGROUND: Drowning death rates in the African region are estimated to be the highest in the world. Data collection and surveillance for drowning in African countries are limited. We aimed to establish the availability of drowning data in multiple existing administrative data sources in Uganda and to describe the characteristics of drowning based on available data. METHODS: We conducted a retrospective descriptive study in 60 districts in Uganda using existing administrative records on drowning cases from January 2016 to June 2018 in district police offices, marine police detachments, fire/rescue brigade detachments, and the largest mortuary in those districts. Data were systematically deduplicated to determine and quantify unique drowning cases. RESULTS: A total of 1435 fatal and non-fatal drowning cases were recorded; 1009 (70%) in lakeside districts and 426 (30%) in non-lakeside districts. Of 1292 fatal cases, 1041 (81%) were identified in only one source. After deduplication, 1283 (89% of recorded cases; 1160 fatal, 123 non-fatal) unique drowning cases remained. Data completeness varied by source and variable. When demographic characteristics were known, fatal victims were predominantly male (n=876, 85%), and the average age was 24 years. In lakeside districts, 81% of fatal cases with a known activity at the time of drowning involved boating. CONCLUSION: Drowning cases are recorded in administrative sources in Uganda; however, opportunities to improve data coverage and completeness exist. An improved understanding of circumstances of drowning in both lakeside and non-lakeside districts in Uganda is required to plan drowning prevention strategies.

The purpose of this research paper is to assess the response on Facebook to a social marketing campaign for recreational boating safety. The campaign ran for the 2018 and 2019 boating seasons in British Columbia, Canada. Messages related to boating safety were delivered in multi-media formats, including ten Facebook posts. All public comments on the campaign Facebook page in response to the ads were included in the analysis. Comments were reviewed for tone and subject; those that related directly to the campaign or boating safety-related topics, such as alcohol use or enforcement, were labeled positive, negative or neutral in tone. Metrics such as likes and shares were also noted. The overall engagement rate (defined as engagements over people reached) was 4.1%. The posts were liked >7000 times and received 901 shares. A total of 219 comments were analysed. Almost half of the comments were positive (n = 106, 48.4%). Fifty comments were off-topic (22.8%), 45 were neutral (20.5%) and 18 were negative (8.2%). The majority of comments were positive, indicating that the campaign performed as planned and was generally well received by the people for whom it was intended. Comments illuminated prevailing attitudes towards risks, injuries and safety practices related to recreational boating. Positive comments valued safety as an aspect of having a pleasant experience, rather than a barrier. Negative comments were about perceiving reduced fun of boating, rather than objecting to the campaign itself. As a component of a multi-media social marketing strategy, Facebook can be a source of instant feedback from the campaign audience.

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.

Objectives: To explore trends in unintentional fatal drowning among older adults (65 years and older). Methods: Total population retrospective analysis of unintentional fatal drowning among people aged 65 years and older in Australia, Canada and New Zealand (2005-2014) was conducted. Results: 1459 older adults died. Rates ranged from 1.69 (Canada) to 2.20 (New Zealand) per 100,000. Trends in crude drowning rates were variable from year to year. A downward trend was observed in New Zealand (y = -.507ln(x) + 2.9918), with upward trends in Australia (y = .1056ln(x) + 1.5948) and Canada (y = .1489ln(x) + 1.4571). Population projections suggest high annual drowning deaths by 2050 in Australia (range: 120-190; 1.69-2.76/100,000) and Canada (range: 209-430; 1.78-3.66/100,000). Significant locations and activities associated with older adult drowning differed by country and age band. Conclusions: Drowning among older adults is a hidden epidemic claiming increasing lives as the population ages. Targeted drowning prevention strategies are urgently needed in Australia, Canada, New Zealand and other similar countries.

AIM: To explore temporal trends in fatal child drowning and benchmark progress across three high-income countries to provide prevention and future investment recommendations. METHODS: A total population analysis of unintentional fatal drownings among 0- to 19-year-olds in Australia, Canada and New Zealand from 2005 to 2014 was undertaken. Univariate and chi-square analyses were conducted, age- and sex-specific crude rates calculated and linear trends explored. RESULTS: A total of 1454 children drowned. Rates ranged from 0.92 (Canada) to 1.35 (New Zealand) per 100 000. Linear trends of crude drowning rates show both Australia (y = -0.041) and Canada (y = -0.048) reduced, with New Zealand (y = 0.005) reporting a slight rise, driven by increased drowning among females aged 15-19 years (+200.4%). Reductions of 48.8% in Australia, 51.1% in Canada and 30.4% in New Zealand were seen in drowning rates of 0- to 4-year-olds. First Nations children drowned in significantly higher proportions in New Zealand (X2 = 31.7; P < .001). CONCLUSION: Continual investment in drowning prevention, particularly among 0- to 4-year-olds, is contributing to a reduction in drowning deaths; however, greater attention is needed on adolescents (particularly females) and First Nation's children. Lessons can be learned from each country's approach; however, further investment and evolution of prevention strategies will be needed to fully eradicate child drowning deaths.

BACKGROUND: Identification of predictors of outcome at the scene of drowning events could guide prevention, care and resource utilization. This review aimed to describe where, what and how scene predictive factors have been evaluated in drowning outcome studies. METHODS: We reviewed studies reporting scene drowning predictors published between 2003 and 2019. Data extraction included study populations, data sources, predictor factors (victim, incident, rescue, resuscitation and hospital-related), outcome measures and type of analyses. RESULTS: Of 49 studies, 87.6% were from high-income countries, 57.1% used data from only one source (92.9% of these from either hospital or EMS), 73.5% included cases who received medical care and 53.1% defined outcomes as survival or death. A total of 78 different factors were studied; the most commonly studied group of factors described victim demographics, included in 42 studies (85.7%), followed by resuscitation factors, included in 30 studies (61.2%). Few studies described rescue (6.1%). The most frequent statistically significant single predictors of outcome known at the scene were submersion duration (evaluated in 19, predictor in 14) and age (evaluated in 31, predictor in 16). Only 38.7% of studies employed multivariable methods. CONCLUSIONS: Gaps to be addressed in drowning outcomes research include data from low- and middle-income countries, standardized definition of factors to allow evaluation across studies, inclusive study populations that can be generalized beyond those receiving medical care, study rescue and resuscitation factors, use of more meaningful outcomes (survival with good neurologic status) and advanced analyses to identify which factors are true predictors versus confounding variables.

Winter activities on ice are culturally important for many countries, yet they constitute a high safety risk depending upon the stability of the ice. Because consistently cold periods are required to form stable and thick ice, warmer winters could degrade ice conditions and increase the likelihood of falling through the ice. This study provides the first large-scale assessment of winter drowning from 10 Northern Hemisphere countries. We documented over 4000 winter drowning events. Winter drownings increased exponentially in regions with warmer winters when air temperatures neared 0°C. The largest number of drownings occurred when winter air temperatures were between -5°C and 0°C, when ice is less stable, and also in regions where indigenous traditions and livelihood require extended time on ice. Rates of drowning were greatest late in the winter season when ice stability declines. Children and adults up to the age of 39 were at the highest risk of winter drownings. Beyond temperature, differences in cultures, regulations, and human behaviours can be important additional risk factors. Our findings indicate the potential for increased human mortality with warmer winter air temperatures. Incorporating drowning prevention plans would improve adaptation strategies to a changing climate.

BACKGROUND: Drowning is a leading and preventable cause of death that has suffered an attention deficit. Improving drowning data in countries would assist the understanding of the full extent and circumstances of drowning, to target interventions and evaluate their effectiveness. The World Health Organization identifies data collection as a key strategy underpinning effective interventions. This study compares unintentional fatal drowning data collection, management and comparison using the databases of Australia, Canada and New Zealand. METHODS: Cases of fatal unintentional drowning between 1-January-2005 and 31-December-2014 were extracted. Cases were combined into a single dataset and univariate and chi square analysis (p < 0.01) were undertaken. Location and activity variables were mapped and combined. Variables consistently collected across the three countries were compared to the ILCOR Drowning Data Guideline. The authors also recommend variables for a minimum core dataset. RESULTS: Of 55 total variables, 19 were consistent and 13 could be compared across the three databases. When mapped against the ILCOR Drowning Data Guideline, six variables were consistently collected by all countries, with five compared within this study. The authors recommend a minimum core dataset of 11 variables including age, sex, location, activity, date of incident, and alcohol and drug involvement). There were 8176 drowning deaths (Australia 34.1%, Canada 55.9%, New Zealand 9.9%). All countries achieved reductions in crude drowning rates (Australia - 10.2%, Canada - 20.4%, New Zealand - 24.7%). Location and activity prior to drowning differed significantly across the three countries. Beaches (X2 = 1151.0;p < 0.001) and ocean/harbour locations (X2 = 300.5;p < 0.001) were common in Australia and New Zealand, while lakes/ponds (X2 = 826.5;p < 0.001) and bathtubs (X2 = 27.7;p < 0.001) were common drowning locations in Canada. Boating prior to drowning was common in Canada (X2 = 66.3;p < 0.001). CONCLUSIONS: The comparison of data across the three countries was complex. Work was required to merge categories within the 20% of variables collected that were comparable, thus reducing the fidelity of data available. Data sources, collection and coding varied by country, with the widest diversity seen in location and activity variables. This study highlights the need for universally agreed and consistently applied categories and definitions to allow for global comparisons and proposes a core minimum dataset.

The purpose of this review was to examine the range and quality of published injury prevention research, based on study design. Stratified random selection of journals (based on the average annual number of injury prevention publications) was conducted using a published inventory. Hand searches for empirical research articles on unintentional injury prevention in children and youth (0-19â¯years) over the four-year period 2013 to 2016, inclusive were conducted. Of the 380 studies identified, the majority were descriptive (133, 35%) or observational (163, 43%), with more than three quarters of the published studies using a "hypothesis-generating" study design. Only 12 (3%) studies were randomized controlled trials, and of the 44 experimental studies, 19 (43%) did not include a comparison group. Transportation injuries predominated, knowledge/attitude/behaviour outcomes were common, and the most common intervention approach was education. The majority of publications were from high-income countries. This review of injury prevention research in children and youth showed that descriptive studies predominate in the published literature, and hypothesis-testing study designs are relatively infrequent. The findings suggest a need for the injury field to support and promote rigorous analytic study designs. In other words, to enhance and strengthen the evidence base for injury prevention policy and practice, injury prevention researchers should consider a greater focus on determination of cause and effect and evaluation of the effectiveness of interventions, particularly engineering and legislative interventions.
RESUMO
OBJECTIVES: The primary objectives of this work were to (1) identify the risk and/or protective factors associated with playground injuries among children less than 18 years of age and (2) identify interventions/programs/policies aimed at preventing playground-related injuries among children less than 18 years of age. Secondary objectives include a summary of the data that reflect alignment with current playground standards. METHODS: For the primary outcome, 4 databases and 12 online resources were systematically searched to include observational and experimental studies examining risk and/or protective factors or interventions associated with playground injury or outcomes related to playground injury (e.g., risky playground behaviour). Data extraction included study design, participants, outcome, exposure or intervention, data analysis, and effect estimates. The quality of evidence for all studies was assessed using the Downs and Black criteria. RESULTS: This review included studies of moderate quality, revealing a number of risk factors and effective interventions for playground injury. Risk factors included absence of handrails and guardrails on playground equipment, non-impact-absorbing surfacing, and critical fall heights. Effective interventions included modifying playground surfacing and reducing equipment height to less than 1.5 m. CONCLUSION: Equipment- and structure-based playgrounds should adhere to and maintain playground standards in order to reduce the risk of serious injury. Organizations responsible for installing and maintaining playgrounds should consider alternative play spaces that allow children to play outdoors, in a natural environment that supports healthy child development and promotes physical activity.

BACKGROUND: Although water-related fatality rates have changed over time, the epidemiology of drowning in Canada has not recently been examined. In spite of the evidence supporting varying drowning death rates by age, information on how characteristics of drowning incidents differ by age group remains limited. The primary objective of this study was to examine the epidemiology of drowning in Canada. A secondary objective was to describe the characteristics of these drowning incidents as they vary by age group. METHODS: A retrospective descriptive analysis was conducted using data that were collected for incidents occurring in Canada between January 1, 2008 and December 31, 2012. The main outcome variable was a water-related fatality, in the majority of cases (94 %) the primary cause of death was drowning. Age specific frequencies, proportions and rates per 100,000 population were calculated and compared among six age groups. RESULTS: There were 2392 unintentional water-related fatalities identified in Canada between 2008 and 2012. Death rates (per 100,000) varied by age group 0-4 (1.05), 5-14 (0.57), 15-19 (1.27), 20-34 (1.70), 35-64 (1.44), 65+ (1.74). The male to female ratio was 5:1. Differences in the characteristics of drowning by age group were identified across: sex, body of water, urban versus rural location, time of year, activity type, purpose of activity, alcohol involvement, personal flotation device use, accompaniment, and whether a rescue was attempted. CONCLUSIONS: The study results suggest that there may be a need for drowning prevention strategies that are tailored to specific age groups. Rural areas in Canada may also benefit from targeted drowning prevention.
