Background: Veterans have higher suicide rates than matched non-veterans, with firearm suicides being especially prevalent among veterans. We examined whether state firearm laws and state firearm ownership rates are important risk factors for suicide among veterans.

Methods: US veteran's and demographically matched non-veteran's suicide rates, 2002-2019, are modelled at the state level as a function of veteran status, lethal means, state firearm law restrictiveness, household firearm ownership rates and other covariates.

Results: Marginal effects on expected suicide rates per 100 000 population were contrasted by setting household firearm ownership to its 75th versus 25th percentile values of 52.3% and 35.3%. Ownership was positively associated with suicide rates for both veterans (4.35; 95% credible interval (CrI): 1.90, 7.14) and matched non-veterans (3.31; 95% CrI: 1.11, 5.77). This association was due to ownership's strong positive association with firearms suicide, despite a weak negative association with non-firearm suicide. An IQR difference in firearm laws corresponding to three additional restrictive laws was negatively associated with suicide rates for both veterans (-2.49; 95% CrI: -4.64 to -0.21) and matched non-veterans (-3.19; 95% CrI: -5.22 to -1.16). Again, these differences were primarily due to associations with firearm suicide rates. Few differences between veterans and matched non-veterans were found in the associations of state firearm characteristics with suicide rates.

Discussion: Veterans' and matched non-veterans' suicide risk, and specifically their firearm suicide risk, was strongly associated with state firearm characteristics.

Conclusions: These results suggest that changes to state firearm policies might be an effective primary prevention strategy for reducing suicide rates among veterans and non-veterans.

Background: Given the high incidence and heavy burden of ankle sprains in recruits, large-scale, multifactorial investigations into potential risk factors are warranted. This study aimed to identify the incidence of ankle sprains and associated risk factors among new military recruits during their infantry training.

Methods: The study included 365 infantry recruits (aged 18-21 years), who were inducted into service in March 2022. These recruits were monitored for ankle sprains throughout their basicy and advanced infantry training by a physiotherapist. Preinduction smoking habits, physical fitness preparation and recurrent ankle sprains were recorded. Anthropometric measures, lower-extremity functional movement, Achilles tendon structure, perceived ankle instability, and mechanical ankle instability were assessed at the onset of both training periods.

Results: Ankle sprains were diagnosed in 109 trainees (29.9%) during both the basic and the advanced training periods. Preinduction recurrent ankle sprains were reported by 28.2% of the participants. The relative risk of a recruit with preinduction ankle sprains suffering a subsequent sprain during training was 1.66 (p=0.001). Logistic regression analysis indicated that reduced proprioception ability (OR=0.002), higher body mass index (OR=1.08), preinduction recurrent sprains (OR=1.95) and lack of physical fitness preparation (OR=3.12) were related to ankle sprains throughout the complete basic-and-advanced training period. Preinduction recurrent ankle sprains (OR=3.37) and reduced Achilles tendon quality (OR=1.30) were associated with ankle sprains during the advanced training period.

Conclusions: Lower-extremity functional movement, body mass index, preinduction recurrent sprains, physical preparation and reduced Achilles tendon quality were associated with the risk of ankle sprains during training. These findings could contribute to developing prevention and intervention programmes for reducing ankle sprains in military trainees.

Background: Integrating and advancing health equity are a core tenant of the Centers for Disease Control and Prevention's mission. Comprehensive frameworks that clearly conceptualise equity are needed to prioritise and inform the advancement of health equity within public health.

Methods: To help meet this need, the investigative team developed The Continuum of Health Equity Practice & Science (The Continuum). The Continuum was developed in two phases: (1) an initial survey distributed to internal CDC Division of Injury Prevention investigators, and (2) a review of public health frameworks and the current health equity evidence base.

Results: The Continuum is a framework that includes seven key components of health equity and ultimately aims to guide public health practice and research towards the advancement of health equity. To illustrate its usefulness, we provide an example using adolescent suicide for each component of The Continuum and demonstrate how this may inform efforts to advance health equity.

Conclusion: With a specific focus on conceptualising health equity and addressing systemic inequities, The Continuum may be used to inform efforts to advance equity in injury prevention and beyond.

Background and objectives: Crash injury risk is reduced when a child correctly uses an appropriate restraint; however, incorrect restraint use remains widespread. The aim of this study was to determine whether product information developed using a user-driven approach increases correct child restraint use.

Methods: We conducted a two-arm double-blinded parallel randomised controlled trial in New South Wales, Australia 2019-2021. Participants were current drivers who were either an expectant parent or a parent of at least one child residing in the greater Sydney metropolitan area who were interested in purchasing a new child restraint. The intervention was user-driven product information consisting of instructions printed on an A3 sheet of paper, swing tags with key reminders and a video accessed via Quick Response codes printed on the materials. The control group received a postcard summarising legal child restraint requirements. The primary outcome was the correctness of child restraint use observed during home visit approximately 6 months after restraint purchase. Correct use was defined as no serious error or <2 minor errors. The secondary outcome was a count of observed errors.

Results: 427 participants were recruited. Home visits were conducted for 372 (190 intervention and 182 control). Correct use was more common in the intervention group (37.4%) compared with the control group (24.2%, p=0.006). Participants receiving the intervention were 1.87 times more likely to correctly use their restraint than those in the control group (95% CI 1.19 to 2.93).

Conclusions: The results provide evidence for the effectiveness of user-driven instructions as a countermeasure to restraint misuse.

Objective: Adolescent firearm violence poses a serious public health concern. The aim of this study is to explore correlates of access to firearms and firearm carrying patterns among adolescents in 2022. While previous research has documented correlates and risk factors for firearm carrying, the majority of this research has relied on samples collected prior to the COVID-19 pandemic and recent shifts in national patterns of firearm violence.

Methods: We analysed data from the 2022 Florida Youth and Substance Use Survey (FYSAS) (N=41 768). Logistic regression models were used to examine associations between demographic, familial, temperamental, and behavioural factors and both ease of perceived firearm access and patterns of firearm carrying.

Results: The results suggest that gender, grade level, race, residential setting, having a parent in the military, delinquency, depression, bullying and substance use are associated with perceived firearm access. In addition, gender, grade level, residential setting, ease of firearm access, delinquency, substance use, and bullying are all associated with firearm carrying.

Conclusions: Our findings suggest a host of demographic features and behavioural factors are associated with both perceived ease of firearm access and patterns of firearm carrying. Implications of these findings for reducing access to firearms is discussed.

Background: Firearm suicides constitute a major public health issue. Policies that enhance economic security and decrease community-level poverty may be effective strategies for reducing risk of firearm suicide. This study examined the association between state minimum wage and firearm suicide.

Methods: State minimum wage, obtained from Temple's Law Atlas and augmented by legal research, was conceptualised using the modified Kaitz Index and a continuous variable centred on the federal minimum wage. State-level suicide counts were obtained from 2000 to 2020 multiple-cause-of-death mortality data from the National Vital Statistics System. Log-linear regressions were conducted to model the associations between state minimum wage and firearm suicides, stratifying by demographic groups. Analyses were conducted in 2023.

Results: A one percentage point increase in a state's modified Kaitz Index was associated with a 0.3% (95% CI -0.6% to -0.0%) decrease in firearm suicides within a state. A US$1.00 increase in a state's minimum wage above the federal minimum wage was associated with a 1.4% (95% CI -2.1% to -0.6%) decrease in firearm suicides. When stratified by quartile of firearm ownership, the modified Kaitz Index was associated with decreases in firearm suicides most consistently in the two lowest quartiles.

Conclusion: Increasing a state's minimum wage may be a policy option to consider as part of a comprehensive approach to reducing firearm suicides. These findings expand the evidence base for how economic policies may be leveraged to reduce firearm suicides.

Background: Unintentional injuries are a common cause of morbidity and mortality in the under-5s, but undertaking home safety practices can reduce injury risk. Stay One Step Ahead (SOSA) is an evidence-based standardised home safety programme. This study evaluates the cost-effectiveness of SOSA versus usual care in Nottingham, UK.

Methods: Cost-effectiveness analysis from a National Health Service and personal social services perspective. SOSA activity data, injury occurrence and associated short-term healthcare costs were collected within a controlled before-and-after study from 2017 to 2020. The primary outcome was the incremental cost-effectiveness ratio (ICER) per additional home adopting three key safety practices (working smoke alarm, safe poisons storage and fitted stair gate). Secondary outcomes were ICERs per injury avoided and quality-adjusted life-years (QALYs) gained.

Results: SOSA costs £30 per child but reduces short-term healthcare expenditure by £42. SOSA increased the number of homes with three key safety practices by 0.02 per child, reduced injuries per child by 0.15 and gained 0.0036 QALYs per child. SOSA was dominant as it was cheaper and more effective than current practice. ICERs were -£590 per additional home deemed safe, -£77 per injury avoided and -£3225 per QALY gained. Focusing on healthcare expenditure alone, SOSA saved £1.39 for every pound spent.

Conclusions: SOSA is a cost-saving intervention. Commissioners should consider implementing SOSA.

Background: Many home-based interventions have been demonstrated to reduce unintentional and intentional injuries in young children aged 0-4 years, but an understanding of their inclusion in federally-funded home visiting programmes in the USA is needed.

Methods: The study team administered a survey to key informants at each of the 21 home visiting models approved for United States Maternal, Infant, and Early Childhood Home Visiting program funding being implemented in 2023. Respondents were based across the United States and in other developed countries. The survey collected information about the content used by models to address unintentional injury, parental health/wellbeing, and child abuse/neglect in children aged 0-4 years.

Results: Completed surveys were returned by all respondents (n=21). Most models reported the inclusion of some unintentional injury, parental health/well-being and child abuse/neglect content. While models on average covered four of the five child abuse/neglect topics listed, only five of the nine topics listed for unintentional injury and parental health/well-being were covered. Among the services used by models to address topics, covering content via standardised curriculum and referrals were the most frequent while less than one-quarter of models (n=5) provided families with safety equipment to address unintentional injury. Less than half of the models evaluated outcomes from their injury prevention services, and no models conducted cost-effectiveness evaluations.

Conclusions: Home visiting programmes are a promising way to reduce injuries in children at high risk, but further development and evaluation of their injury prevention content could increase their impact in the USA.

Background: Vision Zero aims to eliminate serious and fatal road injuries using a Safe System approach. Safe System principles establish that safety is a shared responsibility; this involves both multisector partners and community engagement. This descriptive study explored multisector partners and community engagement in the development of municipal Vision Zero plans.

Methods: We reviewed all first edition Vision Zero plans published by US municipalities from 2014 to 2022. Using a structured coding tool, we abstracted partner involvement and community engagement strategies used in the development of Vision Zero plans.

Results: We identified, reviewed and abstracted 64 plans. The average number of partner groups per plan was 11.5 (12.0 for municipalities with a population ≥150 000; 10.1 for municipalities <150 000) and was higher for later plans (11.9 for plans published 2019-2022; 10.0 for plans published 2014-2018). Common partner groups engaged in the plan were law enforcement (85.9% of plans), local transportation planning (78.3%), mayor/city council/city manager (78.1%), engineering/public works (78.1%) and schools (73.4%). Community engagement strategies were reported in 71.9% of the plans and were more frequent among municipalities with a population ≥150 000 (76.1%) compared with a population <150 000 (61.1%), and in those with more recent plans (82.1%) versus earlier ones (56.0%). The most common community engagement strategies were public meetings, online surveys and map mark-ups.

Conclusions: These findings highlight the extent to which Vision Zero plans were aligned with core Safe System tenets regarding diverse partner involvement and community engagement. Plan developers should consider the translation of Safe System principles in Vision Zero plan development.
