Health care providers are caring for growing numbers of children with chronic illnesses and research on the effects of various interventions with these children are being increasingly published. Data from a variety of sources indicate that children with chronic illness miss more school than their healthy peers. The relative ease with which school attendance data can be obtained and analyzed and the implications of excessive school absence for children's academic performance, social adjustment, and ultimate capacity to function in society suggest that school absence rates deserve to be more broadly emphasized in research on chronic illness in childhood. Although school absence rates have not been widely used as outcome measures in such studies they do reflect a wide variety of aspects of children's health status and have been shown to be responsive to interventions with children with various physical and mental health problems. Since these rates reflect both health and non-health related factors it is important that investigators recognize the nonspecific nature of this measure and account for non-health related influences either by sampling or analytic techniques.
医疗保健提供者正在照料越来越多患有慢性病的儿童，并且关于针对这些儿童的各种干预措施效果的研究也越来越多地发表。来自各种来源的数据表明，患有慢性病的儿童缺课次数比他们健康的同龄人更多。获取和分析出勤数据相对容易，以及缺课过多对儿童学业成绩、社会适应和最终社会功能能力的影响表明，在儿童慢性病研究中，缺课率值得更广泛地强调。尽管缺课率在这类研究中尚未被广泛用作结果指标，但它们确实反映了儿童健康状况的广泛方面，并且已被证明对患有各种身心健康问题的儿童的干预措施有反应。由于这些比率反映了与健康和非健康相关的因素，因此研究人员认识到这一指标的非特异性性质，并通过抽样或分析技术考虑非健康相关影响非常重要。
