日本 AIM 缺乏基于人群的脑瘫 (CP) 登记系统，因此全国范围内的 CP 患病率尚不清楚。我们的目的是利用政府最近开发的日本健康保险索赔和特定健康检查国家数据库来估计患有 CP 的儿童人数。 方法 研究参与者是 20 岁以下的儿童和青少年，他们在 2012 年 6 月至 2013 年 5 月期间日本所有健康保险计划（社会福利和老年健康保险除外）发出的索赔中多次被指定 CP 诊断代码。 结果 诊断出 CP 的参与者人数为44 381. 患有脑瘫的男性人数 (25 237) 多于女性人数 (19 144)。 4 岁时，每 1000 人中 CP 患病率峰值为 2.39，并随着年龄的增长而逐渐下降。 5 至 9 岁时，每 1000 人中 CP 患病率为 2.27 例。 CP 住院患者和门诊患者人数分别为 9126 例 (20.6%) 和 35 255 例 (79.4%)。 解释 我们对 5 至 9 岁每 1000 人中 CP 患病率的估计处于日本先前研究的较高范围内，并且接近欧洲国家报告的数字。
AIM Japan lacks a population-based registration system for cerebral palsy (CP), therefore the nationwide prevalence of CP is unknown. Our aim was to estimate the number of children with CP using the National Database of Health Insurance Claims and Specific Health Checkups of Japan, which has been recently developed by the government.METHOD Study participants were children and adolescents aged below 20 years, who had been assigned CP diagnosis codes more than once in claims issued between June 2012 and May 2013 from all health insurance schemes in Japan, except for Social Welfare and Elderly Health Insurance.RESULTS The number of participants with diagnosed CP was 44 381. The number of males with CP (25 237) was greater than the number of females (19 144). Peak CP prevalence per 1000 population was 2.39 at age 4 years, and this gradually declined with age. The prevalence of CP per 1000 population was 2.27 at age 5 to 9 years. The numbers of inpatients and outpatients with CP were 9126 (20.6%) and 35 255 (79.4%) respectively.INTERPRETATION Our estimation of CP prevalence per 1000 population at age 5 to 9 years lay in the higher range of figures from previous studies in Japan, and was close to figures reported by European countries.
