The goal of this systematic review was to synthesize studies that examined the health-related quality of life of preschool- and school-aged children, adolescents, and young adults who were born preterm and/or at very low birth weight.
We searched 7 databases up to September 2006 (Medline, PubMed, Embase, EBM Reviews, Cumulative Index of Nursing and Allied Health Literature, PsycINFO, and the Educational Resource Information Center) as well as gray literature sources. We independently screened studies and included them only if a quality-of-life outcome measure was used and findings compared preterm, very low birth weight, or extremely low birth weight infants with term or normal birth weight peers. We independently assessed the methodologic quality of each study by using criteria adapted from the Centre for Reviews and Dissemination.
Fifteen cohort or cross-sectional studies met the review criteria. In 6 studies of preschool-aged children, differences were found between study and control groups, suggesting that many preschool children born preterm or at very low birth weight perform more poorly than their peers in physical, emotional, and/or social functioning. Extremely low birth weight school-aged children had lower health utility scores compared with their peers, and similar results were found for adolescents. Parents of preterm and very low birth weight teens noted significantly poorer performance in their child's global health, behavior, and physical functioning, whereas the teenagers themselves did not. In young adulthood, differences in physical functioning remained, but subjective quality of life was similar to normal birth weight peers.
The effects of preterm birth/very low birth weight on health-related quality of life seem to diminish over time, which possibly reflects issues related to a child's report versus a parent-proxy report, differing definitions of health-related quality of life, and adaptation of individuals over time, versus true change in health-related quality of life.
本系统评价的目的是综合各项研究,这些研究考察了早产和/或出生体重极低的学龄前、学龄儿童、青少年及青年的健康相关生活质量。
截至2006年9月,我们检索了7个数据库(医学索引数据库、医学期刊数据库、荷兰医学文摘数据库、循证医学评价数据库、护理及相关健康文献累积索引数据库、心理学文摘数据库和教育资源信息中心数据库)以及灰色文献来源。我们独立筛选研究,只有当使用了生活质量结局指标且研究结果将早产、出生体重极低或出生体重极极低的婴儿与足月或出生体重正常的同龄人进行比较时,才纳入这些研究。我们使用从循证医学中心改编的标准,独立评估每项研究的方法学质量。
15项队列研究或横断面研究符合评价标准。在6项针对学龄前儿童的研究中,研究组与对照组之间存在差异,这表明许多早产或出生体重极低的学龄前儿童在身体、情感和/或社会功能方面的表现不如同龄人。与同龄人相比,出生体重极极低的学龄儿童的健康效用得分较低,青少年也有类似结果。早产和出生体重极低的青少年的父母指出,他们孩子的整体健康、行为和身体功能明显较差,而青少年自己却没有这样认为。在青年期,身体功能方面的差异仍然存在,但主观生活质量与出生体重正常的同龄人相似。
早产/出生体重极低对健康相关生活质量的影响似乎会随着时间的推移而减弱,这可能反映了与儿童报告与父母代理报告相关的问题、健康相关生活质量的不同定义、个体随时间的适应情况,而非健康相关生活质量的真正变化。
