Developmental coordination disorder (DCD) is defined as an impairment in the development of motor coordination that interferes with academic achievement or activities of daily living (DSM-IV). DCD has been reported to affect 5% to 9% of children in the normal population. This study describes the prevalence of DCD in a cohort of extremely low birth weight children (ELBW, < or = l800 g) at 8.9 years of age, from which were excluded children with major impairments. Seventy-three children were included in the study group, along with 18 term-born, socially matched controls. Of the 73 ELBW children, 37 (51%) were classified as having DCD. ELBW children with DCD also had significantly lower Performance IQ (PIQ) scores and were more likely (43%) to have a learning difficulty in arithmetic than ELBW children who did not have DCD. This study found that DCD is a common problem in school-aged ELBW children.
发育性协调障碍（DCD）被定义为运动协调发育受损，这种受损会干扰学业成绩或日常生活活动（《精神疾病诊断与统计手册》第四版）。据报道，正常人群中5%至9%的儿童受DCD影响。本研究描述了一组极低出生体重儿（ELBW，≤1800克）在8.9岁时DCD的患病率，其中排除了有严重损伤的儿童。研究组纳入了73名儿童，还有18名足月出生、社会匹配的对照组儿童。在73名ELBW儿童中，37名（51%）被归类为患有DCD。与没有DCD的ELBW儿童相比，患有DCD的ELBW儿童的操作智商（PIQ）得分也显著更低，并且更有可能（43%）在算术方面存在学习困难。本研究发现，DCD在学龄期ELBW儿童中是一个常见问题。
