In 2013, the state of Maryland passed the Firearms Safety Act limiting the private sales of handguns, which did not apply to long guns often used for hunting (e.g., rifles and shotguns). This decreased the accessibility of handguns relative to long guns. We assessed the frequency of long gun suicides in the years before and after the policy change during winter season, which encompasses hunting season in Maryland.
We performed a retrospective analysis on all 4107 well-characterized adult suicides caused by firearms in Maryland from 2003 through 2019. Logistic regression was performed, stratifying by decedent sex, race, and age.
While handgun suicides decreased in the period after 2013's Firearm Safety Act (p < 0.008), wintertime long gun suicides increased after 2013 (p < 0.004). Caucasian race (p < 0.006), male sex (p < 0.005), and middle age (p < 0.001) were significantly associated with wintertime long gun suicides after 2013.
Our findings suggest that while the 2013 Firearms Safety Act decreased handgun suicides significantly, it did not reduce long gun suicides and there may even have been replacement with long guns during hunting season, when rifles are out and accessible. This association was most prominent among the demographics most likely to hunt (Caucasian, middle-aged, and male).
2013年,马里兰州通过了《枪支安全法案》,限制手枪的私人销售,但该法案不适用于常用于狩猎的长枪(如步枪和霰弹枪)。这降低了手枪相对于长枪的可获得性。我们评估了在政策变化前后的冬季(包括马里兰州的狩猎季节)长枪自杀的频率。
我们对2003年至2019年马里兰州4107例特征明确的成年枪支自杀案例进行了回顾性分析。进行了逻辑回归分析,并按死者的性别、种族和年龄进行分层。
虽然2013年《枪支安全法案》实施后手枪自杀率有所下降(p<0.008),但2013年后冬季长枪自杀率有所上升(p<0.004)。白人种族(p<0.006)、男性(p<0.005)和中年(p<0.001)与2013年后冬季长枪自杀显著相关。
我们的研究结果表明,虽然2013年《枪支安全法案》显著降低了手枪自杀率,但并没有减少长枪自杀率,甚至在狩猎季节(此时步枪可用且容易获得)可能出现了用长枪替代手枪自杀的情况。这种关联在最有可能狩猎的人群(白人、中年人和男性)中最为突出。
