Abstract：
BACKGROUND: School attendance and life participation, particularly sport, is a high priority for children with chronic kidney disease (CKD). This study is aimed at assessing the association between CKD stage, sports participation, and school absences in children with CKD.
METHODS: Using data from the binational Kids with CKD study (ages 6-18 years, n = 377), we performed multivariable regression to evaluate the association between CKD stage, school absences, and sports participation.
RESULTS: Overall, 62% of participants played sport with the most frequent sport activities engaged in being swimming (17%) and soccer (17%). Compared to children with CKD 1-2, the incidence rate ratios (IRR) (95% CI) for sports participation amongst children with CKD 3-5, dialysis, or transplant were 0.84 (0.64-1.09), 0.59 (0.39-0.90), and 0.75 (0.58-0.96), respectively. The median (IQR) days of school absences within a four-week period were 1 day (0-1), with children on dialysis reporting the highest number of school absences (9 days (5-15)), followed by transplant recipients (2 days (1-7)), children with CKD 3-5 (1 day (0-3)), and with CKD 1-2 (1 day (0-3)). Duration of CKD modified the association between CKD stage and school absences, with children with a transplant experiencing a higher number of missed school days with increasing duration of CKD, but not in children with CKD 1-5 or on dialysis (p-interaction < 0.01).
CONCLUSIONS: Children receiving dialysis and with a kidney transplant had greater school absences and played fewer sports compared to children with CKD stages 1-2. Innovative strategies to improve school attendance and sport participation are needed to improve life participation of children with CKD.

摘要：
背景：学校出勤率和生活参与，尤其是体育,是慢性肾病（CKD）儿童的优先事项。本研究旨在评估CKD分期之间的关联，体育参与,CKD儿童缺课。
方法：使用来自患有CKD的双民族儿童研究的数据（年龄6-18岁，n=377),我们进行了多变量回归来评估CKD分期之间的关联，学校缺勤,体育参与。
结果：总体而言，62％的参与者参加了体育运动，其中最常见的体育活动是游泳（17％）和足球（17％）。与CKD1-2儿童相比，CKD3-5儿童的运动参与发生率（IRR）（95％CI），透析，或移植为0.84（0.64-1.09），0.59（0.39-0.90），和0.75（0.58-0.96），分别。四周内缺课天数中位数(IQR)为1天(0-1),接受透析的儿童报告缺课人数最多(9天(5-15天))，其次是移植受体（2天（1-7）），儿童CKD3-5（1天（0-3）），和CKD1-2（1天（0-3））。CKD的持续时间改变了CKD阶段和缺课之间的关系，随着CKD持续时间的增加，移植儿童的缺课天数增加，但在CKD1-5或透析儿童中没有（p相互作用<0.01）。
结论：与CKD1-2期儿童相比，接受透析和肾脏移植的儿童缺勤更多，运动更少。需要采取创新策略来提高入学率和体育参与度，以改善CKD儿童的生活参与度。
