This longitudinal study tested the hypothesis that neurobehavioral disinhibition (ND) in childhood, mediated by alcohol use, portends risky sexual behavior (number of sexual partners) in midadolescence.
Participants were 410 adolescent boys. Neurobehavioral disinhibition was assessed at 11.3 years of age. Frequency and quantity of alcohol use on a typical drinking occasion were assessed at 13.4 years of age at first follow-up, and sexual behavior at 16.0 years at second follow-up.
Quantity of alcohol consumed on a typical drinking occasion, but not frequency of alcohol use, mediated the relation between ND and number of sexual partners.
These findings indicate that number of sexual partners in midadolescence is predicted by individual differences in boys' psychological self-regulation during childhood and moderate alcohol consumption in early adolescence, and that ND may be a potential target for multi-outcome public health interventions.
本纵向研究旨在验证以下假设,即儿童时期的神经行为抑制(ND)通过饮酒来介导,预示着青少年中期的风险性行为(性伴侣数量)。
参与者为 410 名青春期男孩。在 11.3 岁时评估神经行为抑制程度。在首次随访时的 13.4 岁时评估典型饮酒时的饮酒频率和数量,在第二次随访时的 16.0 岁时评估性行为。
在典型饮酒时的饮酒量,而不是饮酒频率,介导了 ND 与性伴侣数量之间的关系。
这些发现表明,青少年中期的性伴侣数量是由儿童期男孩心理自我调节的个体差异和青少年早期的适度饮酒所预测的,并且 ND 可能是多结果公共卫生干预的潜在目标。
