Purpose Examine associations between childhood behavioural problems with criminal behaviour, emotional disorders, substance use and unemployment in early adulthood in two birth cohorts from a middle- and high-income country. Methods Data were utilised from large, prospective birth cohorts in Brazil (1993 Pelotas Birth Cohort; N = 3939) and the UK (Avon Longitudinal Study of Parents and Children; ALSPAC; N = 5079). Behavioural problems were reported on by parents at age 11 years (including disobeys, temper, lies, fights, steals). Outcomes (assessed with youth between ages 22 and 24 years) included criminal behaviour, emotional disorders, substance use and NEET (not in education, employment or training). Results In both cohorts, children with ‘conduct problems’ (those with increased probability of all five behaviours at age 11), were at higher risk of criminal behaviour, emotional disorders and NEET in adulthood compared to those with ‘low problems’. Associations for ‘conduct problems’ were stronger in Pelotas compared to ALSPAC for hazardous alcohol use [Pelotas: risk ratio = 1.39, 95% CI = 1.14–1.70; ALSPAC: risk ratio = 0.76, 95% CI = 0.57–1.02] and illegal drug use [Pelotas: risk ratio = 1.32, 95% CI = 1.16–1.50; ALSPAC: risk ratio = 1.05, 95% CI = 0.91–1.20], whereas associations for criminal behaviour [Pelotas: risk ratio = 1.92, 95% CI = 1.29–2.86; ALSPAC: risk ratio = 2.75, 95% CI = 2.04–3.73] and NEET [Pelotas: risk ratio = 1.38, 95% CI = 1.13–1.70; ALSPAC: risk ratio = 3.04, 95% CI = 1.99–4.65] were stronger in ALSPAC. Conclusions Childhood conduct problems were associated with criminal behaviour, emotional disorders and unemployment in adulthood in both Brazil and the UK. Additional associations were found for substance use in Brazil.

成年早期的儿童行为问题和不良后果：巴西和英国出生队列的比较

目的检查来自中高收入国家的两个出生队列中儿童犯罪行为与犯罪行为，情绪障碍，药物滥用和成年早期失业之间的关联。方法使用了巴西（1993年Pelotas出生队列； N = 3939）和英国（Avon父母与儿童纵向研究； ALSPAC； N = 5079）的大型预期出生队列的数据。父母在11岁时就举报了行为问题（包括违抗，脾气，说谎，打架，偷窃）。结果（对22至24岁的年轻人进行评估）包括犯罪行为，情绪障碍，药物滥用和NEET（不在教育，就业或培训中）。结果在这两个队列中，都有“品行问题”的儿童（那些在11岁时出现所有五种行为的可能性增加），与“低问题”人群相比，成年后犯罪行为，情绪障碍和NEET的风险更高。与使用有害酒精的ALSPAC相比，佩洛塔州的“行为问题”关联性更高[佩洛塔州：风险比= 1.39，95％CI = 1.14-1.70；ALSPAC：风险比= 0.76，95％CI = 0.57–1.02]和非法使用毒品[Pelotas：风险比= 1.32，95％CI = 1.16–1.50；ALSPAC：风险比= 1.05，95％CI = 0.91-1.20]，而犯罪行为的关联性[Pelotas：风险比= 1.92，95％CI = 1.29–2.86；ALSPAC：风险比= 2.75，95％CI = 2.04–3.73]和NEET [Pelotas：风险比= 1.38，95％CI = 1.13–1.70；ALSPAC：ALSPAC的风险比= 3.04，95％CI = 1.99–4.65]。结论童年行为问题与犯罪行为有关，巴西和英国的情绪障碍和成年失业。在巴西发现了其他物质使用协会。电子补充材料本文的在线版本（10.1007 / s40865-019-00126-3）包含补充材料，授权用户可以使用。
