Introduction: Numerous public health and transportation studies have established a strong link between low-socioeconomic status and impaired driving. However, few analyze how a neighborhood’s socioeconomic environment influences individual driving behavior. Method: To address this gap, we conducted a spatial econometric analysis at the neighborhood level, assessing the impact of socioeconomic conditions on alcohol and psychoactive drug-related crashes within zip code areas that are neighbored to each other. We merged hospital and crash data to create a dataset of drivers involved in substance-positive crashes through probabilistic data linkage. Socioeconomic factors including poverty, unemployment, income, and education were measured at the zip code level. Results: The spatial modeling results indicate that adverse socioeconomic conditions were associated with higher rates of substance-positive driving crashes in the zip code area and its neighboring zip code areas. Specifically, higher poverty rates were linked to a rise in substance-positive driving crashes in neighboring zip code areas. In comparison, a zip code area with a higher unemployment rate was linked with lower rates of such crashes. Additionally, a higher share of bachelor’s degree holders was associated with fewer substance-positive driving, while median income shows no effect. Practical applications: These findings highlight the need for targeted substance abuse prevention and treatment programs, alongside workforce development initiatives and increased access to supportive resources, in low-socioeconomic areas as part of road safety programs.
大量的公共健康和交通研究已经建立了低社会经济地位和驾驶障碍之间的紧密联系。然而,很少有人分析社区的社会经济环境如何影响个人的驾驶行为。方法:为了解决这一差距,我们在社区层面进行了空间计量分析,评估了社会经济条件对彼此相邻的邮政编码区域内酒精和精神药物相关撞车事故的影响。我们合并了医院和车祸数据,通过概率数据链接创建了一个涉及药物阳性车祸的司机数据集。包括贫困、失业、收入和教育在内的社会经济因素在邮政编码水平上进行了测量。结果:空间模拟结果表明,不利的社会经济条件与邮政编码区及其邻近邮政编码区较高的物质阳性驾驶碰撞率相关。具体来说,较高的贫困率与邻近邮政编码地区物质阳性驾驶事故的增加有关。相比之下,失业率较高的邮政编码地区发生此类事故的几率较低。此外,较高的学士学位持有者比例与较少的药物阳性驾驶有关,而中等收入则没有影响。实际应用:这些研究结果强调,在社会经济水平较低的地区,需要有针对性的药物滥用预防和治疗方案,以及劳动力发展倡议和增加获得支持性资源的机会,作为道路安全方案的一部分。

Introduction: Spatial disorientation (SD) is a well-known risk factor across aviation operations but is a particular risk within general aviation (GA). While previous work has examined historical rates of SD related accidents in GA, modern analyses of SD accidents that account for overall changes to the GA environment are limited. Methods: The current analysis investigates recent trends from 2003 to 2021 in SD GA fatal accidents and compares these trends to historical analyses, while incorporating context about changes to the overall GA landscape. Results: While fatal SD GA accidents rates and overall GA accident rates have declined since previous analyses in the 1990s, the percent fatality associated with SD (94 %) remains remarkedly high. Demographics of pilots involved in these accidents include mostly pilots with less than 500 h of flight time, similar to previous analyses, but the current trends are pointing to a slightly older pilot population, most commonly in the age 60–69 age range. Further, an increase in positive toxicology findings in fatal SD GA accidents is described in the current data, with a quarter of all SD GA accidents involving a positive toxicology finding for a potentially impairing substance. Finally, changes to the type of aircraft available may underlie a portion of recent trends associated with SD-related fatal GA accidents. Conclusions: Overall, these findings highlight the importance of increased and targeted awareness and education efforts for the changing trends in spatial disorientation in general aviation, particularly given the high fatality rates associated with its occurrence. Practical Application: Spatial disorientation continues to be a high-risk factor for fatal accidents in general aviation. Education and awareness campaigns centered around spatial disorientation could use these findings to target the current trends in SD accidents, and highlight the interaction between potentially impairing substances and SD.
空间定向障碍(SD)是航空运营中众所周知的风险因素,但在通用航空(GA)中是一种特殊的风险。虽然以前的工作已经研究了GA中SD相关事故的历史发生率,但对GA环境总体变化的SD事故的现代分析有限。方法:当前的分析调查了2003年至2021年SD GA致命事故的最新趋势,并将这些趋势与历史分析进行了比较,同时结合了GA整体景观变化的背景。结果:虽然致命的SD GA事故率和总体GA事故率自20世纪90年代的先前分析以来有所下降,但与SD相关的死亡率(94%)仍然非常高。与之前的分析类似,涉及这些事故的飞行员的人口统计数据主要包括飞行时间少于500小时的飞行员,但目前的趋势表明,飞行员的年龄略大,最常见的年龄在60-69岁之间。此外,在目前的数据中描述了致命的SD GA事故中阳性毒理学发现的增加,所有SD GA事故中有四分之一涉及潜在损害物质的阳性毒理学发现。最后,可用飞机类型的变化可能是最近与sd相关的致命GA事故相关趋势的部分原因。结论:总的来说,这些发现突出了加强和有针对性的认识和教育工作对于通用航空中空间定向障碍的变化趋势的重要性,特别是考虑到其发生相关的高死亡率。实际应用:空间定向障碍仍然是通用航空致命事故的高风险因素。以空间定向障碍为中心的教育和宣传活动可以利用这些发现来针对当前SD事故的趋势,并强调潜在损害物质与SD之间的相互作用。

Introduction: Little occupational health and safety information exists on American Indian or Alaska Native (AI/AN) workers. The objective of this study is to describe the leading underlying causes of death among AI/AN workers by occupation and industry. Methods: Mortality data indicating decedents’ race as: (1) ‘American Indian/Alaska Native’ (AI/AN) single-race or (2) AI/AN single-race and AI/AN in combination with any other race(s) were abstracted from 2020 to 2022 public use multiple cause of death files maintained in the National Vital Statistics System. Records with decedents: (a) 15 years of age and older, (b) residing in the United States, and (c) having both usual industry and usual occupation were included in this analysis. Mortality data were analyzed by occupation and industry for the 15 leading causes of death and COVID-19. Age-adjusted proportionate mortality ratios (PMRs) and 95% confidence intervals were calculated for usual occupation groups and usual industry groups for these causes of death. Results: Occupation groups with the highest number and proportion of deaths were construction and extraction (AI/AN single-race 15.9%; AI/AN combined 14.9%) and production (AI/AN single-race and combined 8.8%). The industry groups with the highest number and proportion of deaths include construction (AI/AN single-race 15.7%; AI/AN combined 14.9%) and healthcare and social assistance (AI/AN single-race 12.3%; AI/AN combined 12.2%). The three highest PMRs by occupation were suicide in the military and computer and mathematical occupations and homicide in construction and extraction occupations. The three highest PMRs by industry were suicide in the military and utilities industries and hypertension in the information industries. The top three causes of death for AI/AN combined race decedents were heart disease, cancer, and COVID-19. Conclusion: These results indicate that causes of death among AI/AN workers vary by specific occupations and industries. Focusing intervention and prevention in these highest risk occupations and industries may reduce morbidity and mortality among workers. Practical Applications: The results of this study can be used by tribes, tribal organizations, tribal leaders, and researchers to assist in prevention, control methods, and tailored communication efforts.
关于美国印第安人或阿拉斯加原住民(AI/AN)工人的职业健康和安全信息很少。本研究的目的是按职业和行业描述人工智能/人工智能工人死亡的主要潜在原因。方法:从国家生命统计系统中保存的2020年至2022年公共使用多死因档案中提取显示死者种族的死亡率数据:(1)“美国印第安人/阿拉斯加原住民”(AI/AN)单一种族或(2)AI/AN单一种族和AI/AN与任何其他种族的组合。与死者有关的记录:(a) 15岁及以上,(b)居住在美国,(c)通常的行业和通常的职业都包括在本分析中。按职业和行业分析15种主要死亡原因和COVID-19的死亡率数据。针对这些死因,计算了通常职业组和通常行业组的年龄调整比例死亡率(pmr)和95%置信区间。结果:建筑采掘业(AI/AN单种族15.9%,AI/AN联合14.9%)和生产业(AI/AN单种族和联合8.8%)是死亡人数和比例最高的职业。死亡人数和比例最高的行业包括建筑业(AI/AN单一种族15.7%;AI/AN合并14.9%)和医疗保健和社会援助(AI/AN单一种族12.3%;AI/AN合并12.2%)。按职业划分,自杀率最高的三个职业是军队、计算机和数学职业的自杀率,以及建筑和采掘业的凶杀率。按行业分类,pmr最高的三个行业分别是军事和公用事业行业的自杀和信息行业的高血压。人工智能/人工智能联合种族死亡的前三大原因是心脏病、癌症和COVID-19。结论:这些结果表明AI/AN工人的死亡原因因特定职业和行业而异。将干预和预防的重点放在这些风险最高的职业和行业中,可以降低工人的发病率和死亡率。实际应用:本研究的结果可以被部落、部落组织、部落领袖和研究人员用于协助预防、控制方法和量身定制的沟通工作。

Introduction: The development of models capable of learning visual representations from traffic safety-critical events (SCEs), including crashes and near-crashes, is crucial for advancing road safety. Method: This study proposes a novel supervised contrastive learning (SCL) approach designed to enhance representations of traffic video data for detecting SCEs. SCL integrates supervised and contrastive learning by embedding label information into the contrastive loss, enhancing intra-class cohesion and inter-class separation in the representation space. Leveraging a lightweight video encoder, SCL optimizes representations specifically for video data, addressing the challenges of distinguishing characteristics between SCEs and normal driving scenarios. Results: The proposed approach was evaluated using the Second Strategic Highway Research Program Naturalistic Driving Study video dataset, demonstrating superior performance in representation clustering and downstream three-way event classification tasks compared to benchmark approaches. Practical applications: The improved representations learned through SCL can be directly applied to enhance real-time detection of SCEs in advanced driver assistance systems and automated driving systems. By enabling more reliable identification of SCEs, SCL can support timely driver alerts, proactive collision avoidance maneuvers, and post-incident analysis, ultimately contributing to reduced crash risk and improved road safety.
开发能够从交通安全关键事件(sce)中学习视觉表示的模型,包括碰撞和接近碰撞,对于提高道路安全至关重要。方法:本研究提出了一种新的监督对比学习(SCL)方法,旨在增强交通视频数据的表示,以检测sce。SCL通过在对比损失中嵌入标签信息,增强表征空间中的类内聚和类间分离,将监督学习和对比学习结合起来。利用轻量级视频编码器,SCL优化了专门针对视频数据的表示,解决了区分sce和正常驾驶场景特征的挑战。结果:使用第二战略公路研究计划自然驾驶研究视频数据集对所提出的方法进行了评估,与基准方法相比,该方法在表示聚类和下游三方事件分类任务方面表现出优越的性能。实际应用:在高级驾驶辅助系统和自动驾驶系统中,通过SCL学习到的改进表示法可直接用于增强对SCEs的实时检测。通过更可靠地识别sce, SCL可以支持及时的驾驶员警报,主动避免碰撞机动和事故后分析,最终有助于降低碰撞风险并提高道路安全。

Introduction: Drowning among geriatric individuals is of concern, particularly as rising life expectancy contributes to a growing aging population worldwide. Older adults face heightened vulnerability due to age-related neurocognitive decline, physical impairments, and often inadequate supervision or care. This study examines drowning-related deaths among older adults in the United States and highlights strategies to mitigate these preventable fatalities Methods: A retrospective analysis was conducted using death certificate data from the CDC-WONDER database. The study evaluated demographic and regional disparities in drowning-related death rates among individuals aged 55 and older between 1999 and 2020. Crude and age-adjusted mortality rates (AAMRs) per 100,000 individuals were determined, and temporal changes in trends were evaluated using Joinpoint v5.4. Results: Between 1999 and 2020, 20,466 deaths were attributed to drowning among the geriatric population in the United States, with an AAMR of 12.23 per 100,000 individuals. The average annual percent change (AAPC) in mortality rate was 1.51% (95% CI: 1.21, 1.82), indicating a significant increase over the study period. The AAMR for geriatric drowning deaths rose steadily, with notable disparities across sex, race, geographic region, and urban–rural classification. Males had higher mortality rates than females, and non-Hispanic American Indian/Alaska Natives exhibited the highest overall AAMR among racial groups. The highest mortality was observed in the Western region, while rural areas had slightly higher rates than urban regions. Conclusion: The rising incidence of drowning among older adults presents a significant public health challenge. Age-related declines in mobility, balance, cognition, and chronic health conditions increase vulnerability in aquatic environments. Practical Applications: This study highlights the need for age-specific drowning prevention strategies, including improved supervision, environmental modifications, and community-based education programs tailored for older adults. Enhancing access to water safety training and fall-prevention initiatives in high-risk populations could substantially reduce drowning-related mortality in this vulnerable age group.
引言:老年人的溺水问题令人担忧,特别是随着预期寿命的延长,世界范围内的人口老龄化日益严重。由于与年龄相关的神经认知能力下降、身体损伤以及往往缺乏监督或护理,老年人面临更大的脆弱性。本研究调查了美国老年人中与溺水相关的死亡,并强调了减轻这些可预防死亡的策略。方法:使用CDC-WONDER数据库中的死亡证明数据进行回顾性分析。该研究评估了1999年至2020年间55岁及以上人群溺水相关死亡率的人口统计学和地区差异。确定了每10万人的粗死亡率和年龄调整死亡率(AAMRs),并使用Joinpoint v5.4评估了趋势的时间变化。结果:1999年至2020年间,美国老年人口中有20,466人死于溺水,AAMR为每10万人12.23人。死亡率的平均年百分比变化(AAPC)为1.51% (95% CI: 1.21, 1.82),表明在研究期间显著增加。老年人溺水死亡的AAMR稳步上升,在性别、种族、地理区域和城乡分类中存在显著差异。男性的死亡率高于女性,非西班牙裔美洲印第安人/阿拉斯加原住民在种族群体中表现出最高的总体AAMR。西部地区的死亡率最高,而农村地区的死亡率略高于城市地区。结论:老年人溺水发生率的上升是一个重大的公共卫生挑战。与年龄相关的活动能力、平衡能力、认知能力和慢性健康状况的下降增加了水生环境中的脆弱性。实际应用:本研究强调了针对特定年龄的溺水预防策略的必要性,包括改进监督、环境改造和为老年人量身定制的社区教育计划。在高危人群中加强获得水安全培训和预防跌倒举措的机会,可以大大降低这一脆弱年龄组的溺水相关死亡率。

Introduction: With the increasing use of bicycles, cyclists’ fatalities have risen globally. To address the issue of cycling safety, external factors affecting cyclists’ crashes have been well reviewed. However, there remains a lack of comprehensive knowledge on the risky riding behaviors exhibited by cyclists. The aim of the present study is to address this gap by providing an exhaustive review of scientific publications in this field. Method: For this purpose, 85 studies published between January 2010 and December 2024 were identified using the PRISMA approach. The findings of the literature review indicated an increase in the number of publications related to cyclists’ behavior in recent years. The majority of these studies come from European regions and very limited research studies are available from low-and-middle-income-countries, emphasizing the need for further research in this area. A keyword analysis of the literature was done to identify the classes of risky riding behaviors among cyclists including lack of alertness, lateral instability, lack of conspicuity aids and protective equipment, and errors and violations. Results: The literature review provides a detailed discussion on the prevalence of all risky riding behaviors undertaken by cyclists. These behaviors have been evaluated using various assessment measures, including speed, acceleration, lateral position, gaze behavior, etc. The review provides a detailed description of various factors associated with risky riding behaviors, including cyclists’ characteristics, roadway and traffic characteristics, vehicle characteristics, and environmental conditions. It was observed that cyclists’ characteristics, especially age and gender, have been widely studied in relation to risky riding behaviors, while the number of studies modeling the effect of infrastructure and environment on risky behaviors is considerably low. Practical applications: In light of the observed findings, the study has highlighted the existing research gaps offering recommendations for future studies to reduce risky riding behaviors among cyclists and promote sustainable transportation.
导言:随着自行车使用的增加,骑自行车的人的死亡人数在全球范围内上升。为了解决骑自行车的安全问题,影响骑自行车者撞车的外部因素已经得到了很好的审查。然而,对于骑自行车的人所表现出的危险骑行行为,人们仍然缺乏全面的了解。本研究的目的是通过对这一领域的科学出版物进行详尽的审查来解决这一差距。方法:为此目的,使用PRISMA方法对2010年1月至2024年12月间发表的85项研究进行鉴定。文献综述的结果表明,近年来与骑自行车者行为有关的出版物数量有所增加。这些研究大多数来自欧洲区域,来自低收入和中等收入国家的研究非常有限,强调需要在这一领域进行进一步研究。对文献进行关键字分析,以确定骑自行车者的危险骑行行为类别,包括缺乏警觉性,横向不稳定,缺乏显著辅助和保护设备,以及错误和违规。结果:文献综述提供了一个详细的讨论,所有危险的骑自行车行为的流行。这些行为已被评估使用各种评估措施,包括速度,加速度,横向位置,凝视行为等。该综述详细描述了与危险骑行行为相关的各种因素,包括骑自行车者的特征、道路和交通特征、车辆特征和环境条件。研究发现,骑自行车者的特征,特别是年龄和性别,与危险骑行行为的关系已经得到了广泛的研究,而基础设施和环境对危险骑行行为影响的建模研究却相当少。实际应用:根据观察到的结果,该研究强调了现有的研究差距,为未来的研究提供了建议,以减少骑自行车者的危险骑行行为,促进可持续交通。

Introduction: While much is known about the complexities of fall-related risks among older adults, less is known about the risk for falls among men, and especially older non-Hispanic Black and Hispanic men with chronic conditions. To address this crucial gap in safety research, this study examined factors associated with incident falls (1 fall) and recurrent falling (2+ falls) among non-Hispanic Black and Hispanic men ages ≥60 years with ≥1 chronic condition. Method: Collected with a cross-sectional, web-delivered questionnaire, data were analyzed from a national sample of 779 non-Hispanic Black (58.8%) and Hispanic (41.2%) men. To assess incident and recurrent falls, the number of self-reported falls in the past year was trichotomized (0 falls vs. 1 fall vs. 2+ falls) and used as the dependent variable. A multinomial logistic regression was fitted to assess factors associated with incident and recurrent falls. The model adjusted for sociodemographics, disease characteristics, health status, and social support. Results: On average, participants were aged 66.8 (±5.4) years and reported 3.8 (±2.7) chronic conditions. Seventy-three percent of men reported 0 falls, 12.6% reported 1 fall, and 14.4% reported 2+ falls in the past year. Relative to men reporting 0 falls, Hispanic men (P < 0.05), men with worse general health status (P < 0.05), and those with clinical depression (P < 0.05) were more likely to report incident and recurrent falls, respectively. Men with more comorbidities (P < 0.05) and those with less help/support to manage health problems (P < 0.05) were more likely to report recurrent falls. Conclusions: Findings highlight the importance of multi-component interventions to prevent falls by strengthening disease self-management, addressing mental health, and introducing social support. Practical applications: This study contributes to the understanding of fall-related risks among older non-Hispanic Black and Hispanic men with chronic conditions and highlights the need for interdisciplinary collaboration in fall prevention efforts.
导言:虽然人们对老年人跌倒相关风险的复杂性了解很多,但对男性,特别是患有慢性疾病的非西班牙裔黑人和西班牙裔老年男性跌倒风险知之甚少。为了解决安全性研究中的这一关键空白,本研究在非西班牙裔黑人和西班牙裔年龄≥60岁且≥1种慢性疾病的男性中调查了与意外跌倒(1次跌倒)和复发跌倒(2次以上跌倒)相关的因素。方法:采用横断面网络问卷,对全国779名非西班牙裔黑人(58.8%)和西班牙裔男性(41.2%)的数据进行分析。为了评估偶发和复发性跌倒,过去一年中自我报告的跌倒次数被三分化(0次跌倒vs 1次跌倒vs 2次跌倒),并用作因变量。采用多项逻辑回归来评估与偶发和复发性跌倒相关的因素。该模型根据社会人口统计学、疾病特征、健康状况和社会支持进行了调整。结果:参与者的平均年龄为66.8(±5.4)岁,报告了3.8(±2.7)个慢性疾病。73%的男性在过去一年中跌倒过0次,12.6%的男性跌倒过1次,14.4%的男性跌倒过2次以上。相对于报告0次跌倒的男性,西班牙裔男性(P < 0.05)、总体健康状况较差的男性(P < 0.05)和临床抑郁症患者(P < 0.05)分别更有可能报告偶发跌倒和复发跌倒。有更多合并症的男性(P < 0.05)和在管理健康问题方面得到较少帮助/支持的男性(P < 0.05)更有可能报告复发性跌倒。结论:研究结果强调了通过加强疾病自我管理、解决心理健康问题和引入社会支持等多成分干预措施来预防跌倒的重要性。实际应用:本研究有助于了解老年非西班牙裔黑人和西班牙裔男性慢性疾病患者的跌倒相关风险,并强调了在预防跌倒方面开展跨学科合作的必要性。

Background: Firefighters face significant occupational hazards resulting in fatal and nonfatal injuries as well as illnesses. This study characterizes the costs of workers’ compensation (WC) claims among Ohio firefighters from 2001 to 2020, providing insights for prevention and resource allocation strategies. Methods: WC claims data for public and private fire departments were analyzed. Claims were categorized by type (medical-only vs. lost-time), demographics, tasks that led to the injury/illness, injury/illness events, and diagnoses. Costs included medical care, indemnity payments, and reserves for future anticipated costs, evaluated as of Q2 2022. Results: Among 37,306 claims, costs totaled $542 million. Lost-time claims accounted for $497 million, while medical-only claims totaled $45 million. Overexertion involving outside sources was the most frequent event, contributing to 27% of claims and $176 million in costs. Patient care activities and long-term exposures had disproportionately high cost-to-claim ratios, highlighting their significant financial burden. A notable increase in cancer-related claims was observed following Ohio’s firefighter cancer presumption law implementation in 2017, reflecting the impact of policy changes on claim trends. Conclusions: This analysis highlights the substantial cost of WC claims among firefighters, emphasizing the need for targeted prevention efforts and resource allocation. The findings underscore the impact of policy changes, such as presumption laws, in shaping WC trends. Future research could examine cost differences across firefighter subgroups and assess the long-term impacts of presumption laws on compensation systems. Practical Applications: Insights from this study provide fire departments and policymakers with critical data to prioritize prevention strategies for high cost injuries, such as overexertion and cancer-related conditions. Findings also support the development of policies and resource allocations aimed at improving firefighter safety.
背景:消防员面临严重的职业危害,导致致命和非致命伤害以及疾病。本研究分析了2001年至2020年俄亥俄州消防员工伤赔偿(WC)索赔的成本特征,为预防和资源分配策略提供了见解。方法:对公共和私人消防部门的WC索赔数据进行分析。索赔按类型(仅医疗与损失时间)、人口统计、导致伤害/疾病的任务、伤害/疾病事件和诊断进行分类。费用包括医疗保健、赔款和未来预期费用的准备金,截至2022年第二季度进行评估。结果:在37,306起索赔中,费用总计为5.42亿美元。损失时间索赔占4.97亿美元,而仅医疗索赔总额为4500万美元。与外部来源有关的过度劳累是最常见的事件,占索赔的27%,成本为1.76亿美元。患者护理活动和长期暴露具有不成比例的高成本-索赔比率,突出了他们的重大财务负担。2017年俄亥俄州实施消防员癌症推定法后,癌症相关索赔显著增加,反映了政策变化对索赔趋势的影响。结论:该分析强调了消防员WC索赔的巨大成本,强调了有针对性的预防工作和资源分配的必要性。研究结果强调了政策变化(如推定法)在塑造用水量趋势方面的影响。未来的研究可以检查消防员亚组之间的成本差异,并评估推定法对赔偿制度的长期影响。实际应用:本研究的见解为消防部门和政策制定者提供了关键数据,以优先考虑高成本伤害的预防策略,如过度劳累和癌症相关疾病。研究结果还支持制定旨在改善消防员安全的政策和资源分配。

Introduction: Effective safety management is essential for achieving high safety performance, which is foundational to both employee health and safety and the sustainable development of enterprises. Although substantial research has been conducted on the factors influencing safety performance, current comprehensive understanding remains insufficient. Methods: This study employed the grounded theory approach to identify and code antecedents and moderators of safety performance at four levels: individual, job characteristic, organizational, and social. Based on this analysis, it also developed influencing frameworks for each level, as well as a comprehensive influencing framework. Results: A total of 235 antecedents influencing safety performance were distilled into 47 primary categories, which were ultimately condensed into 19 core categories. At the individual level, these include individual traits, professional quality, psychosomatic health, job behavior, and safety literacy. At the job characteristic level, categories comprise job features, job conditions, organizational climate, and job stress. The organizational level encompasses leadership traits, team traits, safety climate, safety culture, safety commitment and support, safety guidelines, safety management practices, and work management practices. Finally, at the social level, categories consist of socio-economic and technological environments, as well as social safety governance. Similarly, 25 moderators of safety performance were distilled into 14 main categories, which were summarized into 9 core categories. These include personality traits, psychological status, and professional quality at the individual level; job risk at the job characteristic level; and leadership style, safety climate, safety culture, safety support, and safety campaigns at the organizational level. Conclusion: Each level exerts a distinct influence on various dimensions of safety performance, with complex interactions among the influencing factors across different levels. Practical application: The findings of this study can help enterprises identify the root causes of safety performance issues and offer valuable insights for improving safety performance across various levels.

Introduction: Drowning is a leading cause of preventable morbidity and mortality worldwide, accounting for 15,000 deaths across Europe in 2021. Effective policies and legislation are essential to reduce drowning risk, including in Türkiye where 750 people drown annually. However, the extent to which Türkiye has implemented such approaches to prevent drowning remains unclear. This study aimed to determine the presence and strength of selected national policies or legislation that improve safety around water. Method: Environmental scan methodology identified national policy and legislation for five World Health Organization-identified priority areas: disaster risk management; legislation for safety of water-transport for vessels; mandating lifejacket wear; swimming pool legislation (including fencing and other safety measures); and alcohol regulations. Keyword searches identified relevant documents that were thematically analyzed and evaluated. Results: From 568 documents identified, 14 unique documents were included in the study (disaster risk management [n = 1], passenger water-transport vessel safety [n = 8], lifejacket legislation [n = 5], and swimming pool safety [n = 2]). No relevant alcohol regulations were found. Strong legislation exists around passenger water-transport vessel safety including mandated safety inspections, lifesaving equipment and emergency plans. Although lifejackets carriage is mandatory, lifejacket wear is not mandated. There is no requirement for fencing around swimming pools however, some pool safety measures are robust (i.e., depth restrictions, certified lifeguards). Significant gaps remain regarding disaster risk management and alcohol regulations. Conclusion: Considering Türkiye’s drowning burden, strengthening policies and legislation to support drowning prevention, underpinned by an expanded evidence base, is an urgent priority. Practical Applications: This research makes evidence-based recommendations for improving policy and legislative-based approaches to preventing drowning in Türkiye including the development of a national drowning registry, mandating lifejacket wear (as opposed to carriage) and national registration of swimming pools (both public and private) to support enforcement of recommended improvements to legislation around swimming pool fencing.
导读:溺水是世界范围内可预防的发病和死亡的主要原因,2021年在整个欧洲造成1.5万人死亡。有效的政策和立法对于减少溺水风险至关重要,包括在每年有750人溺水的斯里兰卡。然而, rkiye在多大程度上实施了这些预防溺水的方法仍不清楚。本研究旨在确定选定的国家政策或立法的存在和力度,以改善水周围的安全。方法:环境扫描方法确定了世界卫生组织确定的五个优先领域的国家政策和立法:灾害风险管理;船舶水上运输安全立法;强制穿救生衣;泳池法例(包括围栏及其他安全措施);还有酒精管制。关键词搜索确定了主题分析和评估的相关文档。结果:从确定的568份文件中,有14份独特的文件被纳入研究(灾害风险管理[n = 1],客船安全[n = 8],救生衣立法[n = 5]和游泳池安全[n = 2])。没有发现有关酒精的规定。围绕水上客运船舶安全存在强有力的立法,包括强制性安全检查、救生设备和应急计划。虽然携带救生衣是强制性的,但穿救生衣不是强制性的。泳池周围没有围栏的要求,然而,一些泳池安全措施是强有力的(即深度限制,认证救生员)。在灾害风险管理和酒精管制方面仍存在重大差距。结论:考虑到 rkiye的溺水负担,在扩大证据基础的基础上,加强支持溺水预防的政策和立法是当务之急。实际应用:本研究提出了基于证据的建议,以改进以政策和立法为基础的方法,以防止印度尼西亚溺水,包括建立国家溺水登记处,强制要求穿救生衣(而不是携带)和国家游泳池登记(包括公共和私人),以支持执行有关游泳池围栏立法的改进建议。

Significant gaps remain regarding disaster risk management and alcohol regulations. <em>Conclusion:</em> Considering Türkiye’s drowning burden, strengthening policies and legislation to support drowning prevention, underpinned by an expanded evidence base, is an urgent priority. <em>Practical Applications:</em> This research makes evidence-based recommendations for improving policy and legislative-based approaches to preventing drowning in Türkiye including the development of a national drowning registry, mandating lifejacket wear (as opposed to carriage) and national registration of swimming pools (both public and private) to support enforcement of recommended improvements to legislation around swimming pool fencing.</div></div>","PeriodicalId":48224,"journal":{"name":"Journal of Safety Research","volume":"95 ","pages":"Pages 405-415"},"PeriodicalIF":4.4,"publicationDate":"2025-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145415617","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
