Objective:To identify attention profiles at 7 and 13 years, and transitions in attention profiles over time in children born very preterm (VP; <30 weeks’ gestation) and full term (FT), and examine predictors of attention profiles and transitions.Methods:Participants were 167 VP and 60 FT children, evaluated on profiles across five attention domains (selective, shifting and divided attention, processing speed, and behavioral attention) at 7 and 13 years using latent profile analyses. Transitions in profiles were assessed with contingency tables. For VP children, biological and social risk factors were tested as predictors with a multinomial logistic regression.Results:At 7 and 13 years, three distinct profiles of attentional functioning were identified. VP children were 2–3 times more likely to show poorer attention profiles compared with FT children. Transition patterns between 7 and 13 years were stable average, stable low, improving, and declining attention. VP children were two times less likely to have a stable average attention pattern and three times more likely to have stable low or improving attention patterns compared with FT children. Groups did not differ in declining attention patterns. For VP children, brain abnormalities on neonatal MRI and greater social risk at 7 years predicted stable low or changing attention patterns over time.Conclusions:VP children show greater variability in attention profiles and transition patterns than FT children, with almost half of the VP children showing adverse attention patterns over time. Early brain pathology and social environment are markers for attentional functioning.

7 岁和 13 岁早产儿和足月儿的个体注意模式

目的：确定 7 岁和 13 岁时的注意力概况，以及早产儿（VP；<30 孕周）和足月（FT）出生时注意力概况随时间的转变，并检查注意力概况和转变的预测因素。方法: 参与者是 167 名 VP 和 60 名 FT 儿童，在 7 岁和 13 岁时使用潜在轮廓分析对五个注意领域（选择性、转移和分散注意力、处理速度和行为注意）的轮廓进行了评估。使用列联表评估配置文件中的转换。对于 VP 儿童，生物和社会风险因素作为预测因子进行了多项逻辑回归测试。结果：在 7 岁和 13 岁时，确定了三种不同的注意功能概况。与 FT 儿童相比，VP 儿童表现出较差注意力的可能性高出 2-3 倍。7 到 13 年之间的过渡模式是稳定平均、稳定低、改善和下降的关注度。与 FT 儿童相比，VP 儿童具有稳定的平均注意力模式的可能性要低两倍，而具有稳定的低或改善注意力模式的可能性要高出三倍。各组在注意力下降模式方面没有差异。对于 VP 儿童，新生儿 MRI 上的脑部异常和 7 岁时更大的社会风险预示着随着时间的推移，注意力模式会保持稳定的低或不断变化。结论：VP 儿童的注意力特征和转换模式的变异性比 FT 儿童更大，几乎一半的 VP 儿童随着时间的推移表现出不利的注意力模式。
