枪支占美国自杀的大多数，主要是由于致命性和可获得性。根据联邦和马里兰州的法律，长枪比手枪受到的监管要少，这是一个增加自杀风险的问题。这项研究使用马里兰州的数据来确定长枪对该州自杀率的影响。我们假设，长枪使用枪支自杀之间的患病率将增加在农村和年轻population.MethodsThis是一个横断面研究，使用警察和法医的叙述，以确定枪支类型涉及所有3931马里兰州枪自杀2003年至2018年。计算了使用长枪的火器自杀的比例。城乡差异是使用国家卫生统计中心的分类系统确定的。使用逻辑回归计算城乡范围内长枪自杀与手枪自杀的优势比，控制死者人口统计数据。结果从2003年到2018年，28.4%的马里兰州枪支自杀者使用长枪。使用长枪的比例在大多数农村县最高，其中51.6%的枪支自杀是使用长枪，而在大多数城市县为16.8%。年轻人不成比例地使用长枪。对于18岁或以下的死者，44.6%使用长枪，而65岁或以上的死者则为20.2%。与大多数城市县相比，大多数农村县的枪支自杀死亡者使用长枪的可能性高3.74倍（OR=3.74; 95%CI 2.19，6.40; p
BackgroundFirearms account for the majority of US suicides, largely due to lethality and accessibility. Under Federal and Maryland law, long guns are less regulated than handguns which is a concern for increased suicide risk. This study uses Maryland data to ascertain the impact of long guns on suicides in the state. We hypothesize that the prevalence of long gun use among firearm suicides will be increased in rural and young populations.MethodsThis is a cross sectional study using police and medical examiner narratives to identify firearm type involved in all 3931 Maryland gun suicides from 2003 to 2018. Proportions of firearm suicides utilizing long guns were calculated. Urban-rural differences were determined using the National Center for Health Statistics' classification system. Logistic regression was used to calculate odds ratios of long gun to handgun suicides across the urban-rural spectrum, controlling for decedent demographics.ResultsFrom 2003 to 2018, 28.4% of Maryland gun suicides used long guns. The proportion of long guns used was highest in the most rural counties, where 51.6% of firearm suicides were by long gun, compared to 16.8% in the most urban counties. Long guns were disproportionately used by the young. For decedents 18 or younger, 44.6% used long guns, compared to 20.2% in those 65 or older. Compared to the most urban counties, firearm suicide decedents in the most rural counties were 3.74x more likely to use long guns (OR=3.74; 95% CI 2.19, 6.40; p
