Knowledge of obstetric and environmental influences on Developmental Coordination Disorder (DCD) helps provide increased understanding of the mechanisms underlying the disorder. However, the literature to date has not adequately examined the obstetric and environmental risk factors for DCD in a population-based sample. The current study was therefore conducted to explore the prenatal, perinatal, neonatal, and family environmental risk factors for DCD. A total of 2185 children aged 3-10 years from a national representative sample in China were included; the Movement Assessment Battery for Children-2 was used to assess motor function, and a questionnaire was completed by parents. DCD was identified in 156 children according to the DSM-5 criteria. Multilevel logistic regression was used, and comparisons were made between the DCD and non-DCD group. The results confirmed that male sex, BMI score, preterm birth, and some prenatal conditions are significant risk factors for DCD. Parents' education level and one-child status as two significant environmental risk factors for DCD appear largely independent of other risk factors in the Chinese population. This study provides an opportunity to explore the etiology of DCD and suggest potential assessment, monitoring and intervention programs for DCD that could be examined in the future.
对发育性协调障碍（DCD）的产科和环境影响的了解有助于增加对该疾病发病机制的理解。然而，迄今为止，文献尚未在基于人群的样本中充分研究 DCD 的产科和环境风险因素。因此，本研究旨在探讨 DCD 的产前、围产期、新生儿和家庭环境风险因素。共纳入了来自中国全国代表性样本的 2185 名 3-10 岁儿童；使用儿童运动评估电池-2 评估运动功能，父母完成问卷调查。根据 DSM-5 标准，确定了 156 名 DCD 儿童。使用多级逻辑回归，并对 DCD 和非 DCD 组进行比较。结果证实，男性、BMI 评分、早产和一些产前状况是 DCD 的显著风险因素。父母的教育水平和作为两个重要环境风险因素的独生子女身份在很大程度上独立于中国人群中的其他风险因素。本研究为探讨 DCD 的病因提供了机会，并提出了未来可能进行评估、监测和干预 DCD 的潜在方案。
