Sexual assault among higher education students has detrimental impacts on the health and educational outcomes of survivors. This systematic review aims to describe and synthesize the available quantitative evidence on sexual assault prevalence among this population. We searched Medline, EMBASE, Global Health, PsycINFO, Web of Science, ERIC, and CINAHL for studies published in English, French, Italian, and Spanish from database inception to August 2020 (updated May 2022). We screened studies using prespecified inclusion criteria for the population and context (registered higher education students), condition (self-reported sexual assault), and study design (quantitative survey). The Joanna Briggs Institute Critical Appraisal Checklist was used to assess study quality. Prevalence estimates disaggregated by type of sexual assault, gender identity, and world region were meta-analyzed using a random-effects model and reported following PRISMA guidance. We identified 131 articles, from 21 different countries. The meta-analyzed prevalence of sexual assault was 17.5% for women, 7.8% for men, and 18.1% for transgender and gender diverse people. Four types of sexual assault were identified: rape, attempted rape, forced sexual touching, and coercive sex. Forced sexual touching was the most common act experienced. The African Region had the highest prevalence estimates for women's sexual assault, and the Western Pacific region had the highest prevalence estimates for men's sexual assault. Higher education institutions, especially those outside of the United States, should commit to the implementation of surveys to monitor sexual assault prevalence and dedicate increased resources to supporting student survivors of sexual assault.

Sexual violence (SV) experienced by higher education students is a prevalent public health problem. Collecting data on SV through self-report surveys in higher education institutions (HEIs) is essential for estimating the scope of the problem, the first step to adequately resourcing and implementing prevention and response programming and policies. However, in the United Kingdom, data is limited. We used data from the cross-sectional Oxford Understanding Relationships, Sex, Power, Abuse and Consent Experiences survey, administered to all students at a university in the United Kingdom in May 2021 (n = 25,820), to estimate the past year prevalence of SV. We analyzed data from respondents who answered at least one question on SV (n = 1,318) and found that 20.5% of respondents experienced at least one act of attempted or forced sexual touching or rape, and 52.7% of respondents experienced at least one act of sexual harassment (SH). We found that women experienced the highest rates of SV. Attempted forced sexual touching was far more common than forced sexual touching, or rape. Sexist remarks or jokes were the most common act of SH. Most acts of SV took place at the university. These findings reveal that the prevalence of SV in HEIs in the United Kingdom could be far higher than what is experienced in the general population. While this study reflects the context in only one institution, it underlines the need for continued monitoring to develop rigorous, evidence-based, and targeted prevention and response strategies.

Despite promising reductions in mortality from infectious diseases, premature death is a still major public health problem in Brazil. However, little is known about which diseases and injury mechanisms are the main causes of premature death. This paper aimed to detail the trends in leading causes of death among children and adolescents in Brazil. Data were extracted from medical death certificates from the Brazilian Mortality Information System for children and adolescents aged 1–19 years for 2000–2020. The 10 leading causes of death for children and adolescents were defined using primary cause of death codes, grouped by death for diseases and mechanism for injury, according to the ICD-10. All analyses were completed in 2022. From 2000 through 2020, there was a total of 772,729 child and adolescent deaths in Brazil. Despite an overall 34% reduction in child and adolescent mortality from 2000 to 2020, improvements were less pronounced for injury-related deaths than for communicable diseases. Therefore, by 2020, over half of deaths were from injury-related causes. Firearm-related injury was by far the leading cause, accounting for 21% of all deaths. There was a 38% reduction in firearm deaths in the last 4 years against a previously increasing trend, and homicide accounted for over 90% of all firearm deaths because suicide by firearm was rare. Injury-related deaths among children and adolescents are a growing concern in Brazil, and firearms are the current leading cause of child and adolescent death. [ABSTRACT FROM AUTHOR]

Neighbourhood environments are a known social determinant of health. Vacant and abandoned buildings and lots and poor or hazardous housing conditions, combined with crime and violence, can affect residents' health and wellbeing. Nationwide Children's Hospital and its partners launched the Healthy Homes initiative in 2008, which sought to improve nearby residents' health and wellbeing by rejuvenating vacant and abandoned properties and increasing homeownership in the South Side neighbourhood of Columbus, Ohio. Between 2008 and mid-2019 the initiative funded 273 repairs or renovations in this neighbourhood. We conducted a ZIP-code-level comparative case study of the Healthy Homes housing interventions using synthetic control methodology to evaluate changes in crime rate in the intervention area compared with those in a synthetic control area. While findings were mixed, we found some evidence of reduced thefts in the Healthy Homes area, relative to its synthetic control. This initiative to repair, rebuild and increase ownership of housing has the potential to reduce crime rates for neighbours of the Nationwide Children's Hospital. [ABSTRACT FROM AUTHOR]

Interrupted time series designs are a valuable quasi-experimental approach for evaluating public health interventions. Interrupted time series extends a single group pre-post comparison by using multiple time points to control for underlying trends. But history bias-confounding by unexpected events occurring at the same time of the intervention-threatens the validity of this design and limits causal inference. Synthetic control methodology, a popular data-driven technique for deriving a control series from a pool of unexposed populations, is increasingly recommended. In this paper, we evaluate if and when synthetic controls can strengthen an interrupted time series design. First, we summarize the main observational study designs used in evaluative research, highlighting their respective uses, strengths, biases and design extensions for addressing these biases. Second, we outline when the use of synthetic controls can strengthen interrupted time series studies and when their combined use may be problematic. Third, we provide recommendations for using synthetic controls in interrupted time series and, using a real-world example, we illustrate the potential pitfalls of using a data-driven approach to identify a suitable control series. Finally, we emphasize the importance of theoretical approaches for informing study design and argue that synthetic control methods are not always well suited for generating a counterfactual that minimizes critical threats to interrupted time series studies. Advances in synthetic control methods bring new opportunities to conduct rigorous research in evaluating public health interventions. However, incorporating synthetic controls in interrupted time series studies may not always nullify important threats to validity nor improve causal inference. [ABSTRACT FROM AUTHOR]

Background: Emerging evidence suggests that cognitive bias modification of interpretations (CBM‐I) is effective in altering interpretation biases and reducing anxiety in adults. Less is known about the impact of CBM‐I in young people, but some recent findings, including a meta‐analysis of combined cognitive bias modification of interpretation and attention techniques, have cast doubt on its clinical utility. Given the current debate, this meta‐analysis sought to establish the independent effects of CBM‐I on interpretations biases and anxiety in youth. Methods: Studies were identified through a systematic literature search of PsycINFO, Ovid MEDLINE, PsycARTICLES, Web of Science and EMBASE between January 1992 and March 2017. Eligible studies aimed to target interpretation biases; did not combine CBM‐I with another intervention; included a control condition; randomly allocated participants to conditions; assessed interpretation bias and/or anxiety as an outcome; included individuals up to age 18; and did not present previously reported data. Reference lists of included articles were checked for further eligible studies, and authors were contacted for unpublished data. Results: We identified 26 studies meeting eligibility criteria that included in the meta‐analysis. CBM‐I had moderate effects on negative and positive interpretations (g = −0.70 and g = −0.52, respectively) and a small but significant effect on anxiety assessed after training (g = −0.17) and after a stressor (g = −0.34). No significant moderators were identified. Conclusions: In contrast to previous meta‐analytic findings, our results indicate that CBM‐I has potential but weak anxiolytic effects in youth. Our findings suggest that it may be premature to disregard the potential value of CBM‐I research and further research in this field is warranted. [ABSTRACT FROM AUTHOR]

Objective: This study aims to characterise the motivations of firearm owners and examine whether firearm ownership motivations and carriage varied by state stand your ground law status.  METHODS: Using a nationally representative survey of US adults in 2023, we asked firearm owners (n=2477) about their firearm motivations and behaviours, including reason(s) for ownership., Results: Of all firearm owners, 78.8% (95% CI 76.0% to 81.0%) owned a firearm for protection, and 58.1% (95% CI 54.3% to 62.0%) carried a firearm outside their home in the last 12 months. Firearm ownership for protection was not significantly associated with stand your ground laws, but firearm carriage was more prevalent in states with stand your ground laws (50.1% (95% CI 47.0% to 53.0%) vs 34.9% (95% CI 25.0% to 46.0%)). Gender (women) and race (minority groups) emerged as key correlates for firearm ownership for protection (vs other ownership motivations). For example, black and Asian women (98.8%) almost exclusively owned firearms for protection., Conclusions: Protection was the dominant reason for firearm ownership in 2023, motivating 65 million Americans to own firearms and appealing to different strata of the population., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Background: Homicide is the leading cause of death among young people in Latin America, one of the world's most violent regions. Poverty is widely considered a key cause of violence, but theories suggest different effects of poverty, depending on when it is experienced in the life-course. Longitudinal studies of violence are scarce in Latin America, and very few prospective data are available worldwide to test different life-course influences on homicide., Methods: In a prospective birth cohort study following 5914 children born in southern Brazil, we examined the role of poverty at birth, in early childhood, and in early adulthood on violence and homicide perpetration, in criminal records up to age 30 years. A novel Structured Life Course Modelling Approach was used to test competing life-course hypotheses about 'sensitive periods', 'accumulation of risk', and 'downward mobility' regarding the influence of poverty on violence and homicide., Results: Cumulative poverty and poverty in early adulthood were the most important influences on violence and homicide perpetration. This supports the hypothesis that early adulthood is a sensitive period for the influence of poverty on lethal and non-lethal violence. Results were replicable using different definitions of poverty and an alternative outcome of self-reported fights., Conclusion: Cumulative poverty from childhood to adulthood was an important driver of violence and homicide in this population. However, poverty experienced in early adulthood was especially influential, suggesting the importance of proximal mechanisms for violence in this context, such as unemployment, organized crime, drug trafficking, and ineffective policing and justice systems., (© The Author(s) 2024.
