Preterm birth (PT) and low birthweight (LBW) are risk factors for cognitive, academic, and behavioral difficulties. Executive functioning, which is an umbrella term encompassing higher-order problem-solving and goal-oriented abilities, may help to understand these impairments. This review article examines executive functioning in PT and LBW children, with a specific focus on adolescence and the functional consequences of executive dysfunction in this age group. We have focused on adolescence as it is a critical period for brain, cognitive and social-emotional development, and a period of increased autonomy, independence and reliance on executive functioning. While more longitudinal research is required, there is evidence demonstrating that the PT/LBW population is at increased risk for impairments across all executive domains. Emerging evidence also suggests that executive dysfunction may partly explain poorer academic and social-emotional competence in PT/LBW adolescents. In conclusion, PT/LBW adolescents exhibit poorer executive functioning, and close surveillance is recommended for high-risk individuals.
早产 (PT) 和低出生体重 (LBW) 是认知、学术和行为困难的风险因素。执行功能是一个涵盖更高阶问题解决和目标导向能力的总称,可能有助于理解这些损伤。本文综述了 PT 和 LBW 儿童的执行功能,特别关注青少年和该年龄组执行功能障碍的功能后果。我们关注青少年时期,因为这是大脑、认知和社会情感发展的关键时期,也是自主性、独立性和对执行功能的依赖增加的时期。虽然需要更多的纵向研究,但有证据表明,PT/LBW 人群在所有执行领域都面临更高的损伤风险。新出现的证据还表明,执行功能障碍可能部分解释了 PT/LBW 青少年较差的学业和社会情感能力。总之,PT/LBW 青少年表现出较差的执行功能,建议对高危个体进行密切监测。
