Objective: 

The objective of this study was to determine whether school readiness differs between children born <30 weeks' gestation who are classified as at risk for developmental coordination disorder (DCD) and those who are not.

Methods: 

This study was a prospective cohort study of children born <30 weeks' gestation. Children were classified as at risk for DCD at a corrected age of 4 to 5 years if they scored <16th centile on the Movement Assessment Battery for Children–Second Edition (MABC-2), had a full scale IQ score of ≥80 on the Wechsler Preschool and Primary Scale of Intelligence–Fourth Edition (WPPSI-IV), and had no cerebral palsy. Children were assessed on 4 school readiness domains: (1) health/physical development [Physical Health domain of Pediatric Quality of Life Inventory (PedsQL), Pediatric Evaluation of Disability Inventory Computer Adaptive Test, and Little Developmental Coordination Disorder Questionnaire], (2) social-emotional development (Strengths and Difficulties Questionnaire and PedsQL psychosocial domains), (3) cognitive skills/general knowledge (WPPSI-IV), and (4) language skills (WPPSI-IV).

Results: 

Of 123 children assessed, 16 were ineligible (IQ < 80 or cerebral palsy: n = 15; incomplete MABC-2: n = 1); 28 of 107 (26%) eligible children were at risk for DCD. Children at risk for DCD had poorer performance on all school readiness domains, with group differences of more than 0.4 SD in health/physical development, social-emotional development, and language skills and up to 0.8 SD for cognitive skills/general knowledge compared with those not at risk of DCD.

Conclusion: 

Being at risk for DCD in children born <30 weeks' gestation is associated with challenges in multiple school readiness domains, not only the health/physical domain.

妊娠 <30 周出生且有发育协调障碍风险的儿童的入学准备情况：一项前瞻性队列研究

客观的： 

本研究的目的是确定妊娠 <30 周出生的、被归类为有发育协调障碍 (DCD) 风险的儿童和没有发育协调障碍风险的儿童之间的入学准备情况是否存在差异。

方法： 

这项研究是一项针对妊娠 <30 周出生的儿童的前瞻性队列研究。如果儿童在儿童运动评估系统第二版 (MABC-2) 中得分< 16%，并且在儿童运动评估中的全量表 IQ 得分≥80，则在 4 至 5 岁的校正年龄时被归类为有患 DCD 的风险。韦克斯勒学前和小学智力量表 - 第四版 (WPPSI-IV)，并且没有脑瘫。儿童在 4 个入学准备领域进行评估：(1) 健康/身体发育 [儿科生活质量量表 (PedsQL) 的身体健康领域、儿科残疾评估量表计算机适应性测试和小发育协调障碍问卷]，(2)社交情感发展（优势和困难问卷和 PedsQL 心理社会领域），(3) 认知技能/常识 (WPPSI-IV)，以及 (4) 语言技能 (WPPSI-IV)。

结果： 

在接受评估的 123 名儿童中，有 16 名不符合资格（IQ < 80 或脑瘫：n = 15；不完整的 MABC-2：n = 1）；107 名符合条件的儿童中，有 28 名 (26%) 有患 DCD 的风险。与其他儿童相比，有发展性协调障碍风险的儿童在所有入学准备领域的表现均较差，在健康/身体发育、社交情感发展和语言技能方面的组间差异超过 0.4 个标准差，在认知技能/常识方面的组间差异高达 0.8 个标准差没有 DCD 的风险。

结论： 

妊娠 < 30 周出生的儿童面临 DCD 风险与多个入学准备领域的挑战相关，而不仅仅是健康/身体领域。
