Platelet monoamine oxidase (MAO) activity was estimated in 70 former delinquent boys and 40 controls now aged 38-46 years. Platelet MAO activity was compared with their early criminal behaviour (before the age of 15) and their late registered criminality from the age of 15). Mean platelet MAO activity in subjects with both early and late criminality was significantly lower than that in former delinquents without late criminality. There was no significant difference in mean platelet MAO activity between controls and delinquents with early but no late criminality. When delinquents with early criminality were divided into a low and a high MAO group, the relative risk to be registered for late criminality was about 3.1 times higher for the subjects in the low MAO group. Thus, individuals with low platelet MAO activity run an increased risk of continued criminal behaviour.
对70名曾有犯罪行为的男孩和40名年龄在38至46岁的对照者进行了血小板单胺氧化酶（MAO）活性评估。将血小板MAO活性与其早期犯罪行为（15岁之前）以及15岁之后登记的后期犯罪情况进行了比较。早期和后期均有犯罪行为的受试者的平均血小板MAO活性显著低于没有后期犯罪行为的曾有犯罪行为者。对照组与仅有早期但无后期犯罪行为的曾有犯罪行为者之间的平均血小板MAO活性没有显著差异。当将有早期犯罪行为的曾有犯罪行为者分为低MAO组和高MAO组时，低MAO组受试者后期被登记犯罪的相对风险高出约3.1倍。因此，血小板MAO活性低的个体持续犯罪行为的风险增加。
