背景身高增长迟缓与不太理想的行为结果和教育成就有关。虽然生长延迟后的追赶性生长可能会导致发育增益，但它也可能是一把双刃剑，对神经认知功能产生影响，如注意力不集中和多动症状。由于以前制度化（PI）的儿童在通过和追赶通过后的增长高度延迟，他们提供了一个队列来测试追赶增长和注意缺陷多动障碍（ADHD）symptoms. MethodsThis study used latent growth curve modeling to examine how catch ‐ up in height ‐ for ‐ age growth is related to attention problems in a population of PI youth followed from adoption in infancy through kindergarten.参与者在进入家庭后三个月内接受评估（入组时年龄：18 - 36个月）。测量人体测量学4次，间隔约7个月。两次访问测量的行为结果与家长和教师报告的ADHD，内化，和外化症状在5岁和kindergarten.ResultsThe斜率的增长高度z分数，但不是截距，与家长和教师报告的ADHD症状的儿童。在控制了内化和外化问题、铁状态、机构护理持续时间、性别和年龄后，四项评估中身高z分数斜率增加一个标准差与ADHD症状增加0.252个标准差相关。增长的斜率也与内化，但不externalizing symptoms.ConclusionsThis研究表明，PI儿童表现出个人的轨迹高度增长postadoption。年龄别身高增长的变化率较高与ADHD症状增加相关。这些结果表明，追赶式增长是以注意力调节不良和过度活跃行为为代价的。
BackgroundHeight growth faltering is associated with less optimal behavioral outcomes and educational achievement. Although catch‐up growth after growth delay may result in developmental gains, it may also present as a double‐edged sword, with consequences for neurocognitive functioning such as symptoms of inattention and hyperactivity. As previously institutionalized (PI) children experience height delays at adoption and catch‐up growth after adoption, they provide a cohort to test associations between catch‐up growth and attention deficit hyperactivity disorder (ADHD) symptoms.MethodsThis study used latent growth curve modeling to examine how catch‐up in height‐for‐age growth is related to attention problems in a population of PI youth followed from adoption in infancy through kindergarten. Participants were assessed within three months of arrival into their families (age at entry: 18–36 months). Anthropometrics were measured four times, approximately 7 months apart. Two visits measured behavioral outcomes with parent and teacher reports of ADHD, internalizing, and externalizing symptoms at age 5 and kindergarten.ResultsThe slope of growth in height z‐scores, but not the intercept, was positively associated with parent‐ and teacher‐reported ADHD symptoms in children. A one standard deviation increase in the slope of height z‐scores across four assessments was associated with a 0.252 standard deviation increase in ADHD symptoms after controlling for internalizing and externalizing problems, iron status, duration of institutional care, sex, and age. The slope of growth was also associated with internalizing but not externalizing symptoms.ConclusionsThis study demonstrates that PI children exhibit individual trajectories of height growth postadoption. Higher rates of change in height‐for‐age growth were associated with increased ADHD symptoms. These results suggest that catch‐up growth comes ‘at the cost’ of poor attention regulation and hyperactive behavior.
