Neonatal intensive care unit survivors (N = 494) from 10 tertiary care centers were evaluated over the first 4 to 5 years of life to determine the relative contributions of birth weight and sociodemographic factors to mental development. Six sociodemographic factors were studied: sex, race, family income, and mother's marital status, age, and educational level; the last five factors also are known to be associated with premature birth. Mental development was measured with the Bayley Scales of Infant Development (12 to 24 months) and the Stanford Binet Intelligence Test (4 to 5 years). Each factor's influence was assessed by multivariate analysis. Birth weight had limited long-term implications; at 4 to 5 years, only infants with birth weights less than 1000 gm had significantly lower scores than those in other birth weight categories. Sociodemographic variables had a greater impact on mental development, with age-dependent differences found between nonwhite and white children and between children with mothers of low, medium, and high educational levels.
来自10个三级护理中心的494名新生儿重症监护病房幸存者在生命的最初4至5年接受了评估，以确定出生体重和社会人口学因素对智力发育的相对影响。研究了六个社会人口学因素：性别、种族、家庭收入、母亲的婚姻状况、年龄和教育水平；已知后五个因素也与早产有关。使用贝利婴儿发育量表（12至24个月）和斯坦福-比奈智力量表（4至5岁）测量智力发育。通过多变量分析评估每个因素的影响。出生体重的长期影响有限；在4至5岁时，只有出生体重低于1000克的婴儿得分明显低于其他出生体重组的婴儿。社会人口学变量对智力发育的影响更大，非白人儿童与白人儿童之间以及母亲教育水平低、中、高的儿童之间存在年龄依赖性差异。
