We examined epidemiological associations between anorexia nervosa (AN) and bulimia nervosa (BN) and risks of committing theft and other crimes in a nationwide female population.
Females born in Sweden during 1979-1998 (N = 957,106) were followed from age 15 for up to 20 years using information on clinically diagnosed AN and BN (exposures), convictions of theft and other crimes (outcomes), psychiatric comorbidities, and familial relatedness from Swedish national registers. We estimated hazard ratios (HRs) of criminality in exposed versus unexposed females using Cox proportional hazards regressions and explored how comorbidities and unmeasured familial factors explained the associations.
The cumulative incidence of convictions of theft (primarily petty theft) and other crimes was higher in exposed females (AN: 11.60% theft, 7.39% other convictions; BN: 17.97% theft, 13.17% other convictions) than in unexposed females (∼5% theft, ∼6% other convictions). The significantly increased risk of being convicted of theft in exposed females (AN: HR = 2.51, 95% confidence interval = [2.29, 2.74], BN: 4.31 [3.68, 5.05]) was partially explained by comorbidities; unmeasured familial factors partially explained the association with convictions of theft in BN but not in AN. Females with BN had a doubled risk of convictions of other crimes, which was partially explained by comorbidities.
Individuals with eating disorders had increased risk for convictions of theft and potentially other crimes. Results underscore the importance of regular forensic screening and encourage research on mechanisms underlying the relation between crime and eating disorder psychopathology and efforts to determine how best to address such relation in treatment.
我们在全国女性人群中研究了神经性厌食症（AN）和神经性贪食症（BN）与盗窃及其他犯罪风险之间的流行病学关联。
利用瑞典国家登记处提供的关于临床诊断的AN和BN（暴露因素）、盗窃及其他犯罪定罪（结局）、精神共病以及家族关系的信息，对1979年至1998年在瑞典出生的女性（N = 957,106）从15岁开始进行长达20年的随访。我们使用Cox比例风险回归估计暴露组与未暴露组女性犯罪的风险比（HR），并探讨共病和未测量的家族因素如何解释这些关联。
暴露组女性（AN：盗窃定罪累积发生率为11.60%，其他犯罪定罪为7.39%；BN：盗窃定罪为17.97%，其他犯罪定罪为13.17%）的盗窃（主要是小偷小摸）及其他犯罪定罪的累积发生率高于未暴露组女性（约5%的盗窃定罪，约6%的其他犯罪定罪）。暴露组女性盗窃定罪风险显著增加（AN：HR = 2.51，95%置信区间 = [2.29, 2.74]，BN：4.31 [3.68, 5.05]），部分可由共病解释；未测量的家族因素部分解释了BN与盗窃定罪之间的关联，但未解释AN与盗窃定罪之间的关联。患有BN的女性其他犯罪定罪风险增加一倍，部分可由共病解释。
饮食失调个体的盗窃及潜在其他犯罪定罪风险增加。结果强调了定期法医筛查的重要性，并鼓励对犯罪与饮食失调心理病理学之间关系的潜在机制进行研究，以及努力确定在治疗中如何最好地处理这种关系。
