This study is designed to investigate the trend of incidence in these countries among different ages and gender groups, cluster countries based on PVF incidence rates, and analyze changes during the years 1990 to 2019.</p> <p><strong>Methods:</strong> At first, countries were clustered using the K-means algorithm, with the number of clusters determined by the elbow method. The clustering was based on the Euclidean distance of physical violence by Firearms (PVF) incidence rates, and the data were sourced from the Global Burden of Disease (GBD) database. The annual changes in the incidence in each cluster were calculated by means of sex and age groups. A heat map was also used to investigate the trend of firearms violence, and Arc map GIS was employed to provide the geographical incidence distribution of firearms violence by gender in 4-time points of 1990, 2000, 2010 and 2019.</p> <p><strong>Results:</strong> The United States, which was placed alone in a cluster, had the highest incidence changes with an increase of 1.44 cases per 100,000 per year. The highest incidence of violence was among American men aged 20-24, which ranged from 150 to 240 cases per 100,000 people between 1990 and 2019.</p> <p><strong>Conclusions:</strong> The study highlights that access to firearms and related laws are key drivers of the increasing trend of PVF in high-income countries. The clustering of countries revealed distinct patterns of PVF incidence, with the USA showing the highest rates. These findings underscore the need for stricter firearm regulations and targeted interventions, particularly for young men aged 20-24, who are most affected by PVF.</p> Moslem Taheri-Soodejani Marzieh Mahmudimanesh Marjan Rasoulian-Kasrineh Seyed Jalaleddin Mousavirad Seyyed Mohammad Tabatabaei Copyright (c) 2025 Journal of Injury and Violence Research 2025-07-08 2025-07-08 17 2 https://jivresearch.org/jivr/index.php/jivr/article/view/1938 <p><strong>Background: </strong>Firearm suicide ranks among the leading causes of death in the U.S. military, with access to personal firearms significantly elevating the risk of firearm-related injuries and death. &nbsp;In this study, we analyzed perceived risks of firearm access and storage among active-duty military service members and embedded civilians with a firearm at home.</p> <p><strong>Methods: </strong>We conducted an anonymous online survey at a single military installation in the United States. Data were analyzed using logistic regression models across four firearm-related risk factors: suicide, others’ suicide, interpersonal violence, and unintentional shootings.</p> <p><strong>Results:</strong> Of the 324 participants, 50.5% reported a minimum of one firearm at the home. Respondents with a minimum of one firearm at home (vs. those without) were less likely to agree that there was a risk of suicide for themselves (6.0% vs. 16.6%) or others (7.8% vs. 21.8%), interpersonal violence (16.4% vs. 26.9%), or unintentional shootings (27.9% vs. 42.3%). After adjusting for age, gender, race, ethnicity, and living alone, respondents with a firearm at home (vs. those without) were significantly less likely to agree that firearm access increased the risk of suicide for themselves (odds ratio [OR]: 0.20; 95% CI: 0.10, 0.40; p &lt;.001) or others (OR 0.19; 95% CI: 0.10, 0.36; p &lt;.001), interpersonal violence (OR: 0.25; 95% CI: 0.15, 0.43; p &lt;.001), or unintentional shootings (OR: 0.22; 95% CI: 0.13, 0.38; p &lt;.001).</p> <p><strong>Conclusions: </strong>Our findings identify opportunities for strengthening messaging to help service members understand and acknowledge risks surrounding a firearm at home and promote secure firearm storage behaviors.</p> <p><em>Keywords</em>:&nbsp;firearm injury, military population, firearm storage practice, firearm access, firearm ownership</p> Makala D.
