Infant placements into out-of-home care have garnered increased research and societal attention, yet the long-term outcomes of this vulnerable group are virtually unknown. This study aims to examine the association between infant placement and criminal offences across the life course, contrasting with general population peers and children placed at later developmental periods. The study includes 622,940 individuals born in Sweden between 1975 and 1981, among whom around 0.2 % ( = 1524) were taken into care during infancy (<12 months). Utilizing Swedish longitudinal population-based register data, sex-stratified hurdle regression analyses, adjusted for individual and family background characteristics, were conducted to investigate the risk and rates of criminal offences ages 15–38. Infants placed in care exhibited higher risks of any criminal offence compared to the general population (men: RR = 1.32, < 0.001, women RR = 1.47, p < 0.001), but lower risks compared to children placed at later ages. Incidence-adjusted rates of offences were also higher among infants compared to their general population peers (men: IRR = 2.54, < 0.001, women: IRR = 2.77, p < 0.001), with differences to other care groups being less pronounced. Infant placement in care is associated with an increased risk of criminal activity over the life course.

家庭外护理婴儿的犯罪结果：全国纵向队列研究


将婴儿安置在户外护理中已经引起了越来越多的研究和社会关注，但这一弱势群体的长期结果几乎未知。本研究旨在探讨婴儿安置与整个生命过程中刑事犯罪之间的关联，与一般人群同龄人和处于发育后期的儿童进行对比。该研究纳入了 1975 年至 1981 年间出生于瑞典的 622,940 人，其中约 0.2% (= 1524) 在婴儿期（<12 个月）受到照顾。利用瑞典基于人口的纵向登记数据，进行性别分层障碍回归分析，并根据个人和家庭背景特征进行调整，以调查 15-38 岁刑事犯罪的风险和比率。与一般人群相比，被照顾的婴儿表现出更高的犯罪风险（男性：RR = 1.32，< 0.001，女性 RR = 1.47，p < 0.001），但与年龄较大的儿童相比，风险较低。与一般人群相比，婴儿的犯罪发生率调整后也较高（男性：IRR = 2.54，< 0.001，女性：IRR = 2.77，p < 0.001），与其他护理组的差异不太明显。婴儿接受护理会增加其一生中犯罪活动的风险。
