A cohort of 78 infants weighing less than 1500 g at birth was followed prospectively to determine the impact of birth weight, age of assessment, and skill area on their developmental performance. Five skill areas were tested using the Griffiths Mental Scales of Development at 6, 12, 24, and 36 months of age. Infants were divided into three birth weight groups: less than 750 g, 750-1000 g, and 1001-1500 g. A significant age and skill interaction was found, with the locomotor and eye-hand skills decreasing consistently over time, and the personal-social and hearing and speech skills initially decreasing and then rising from 12 to 36 months. Infants born at less than 1000 g consistently performed more poorly than those born at 1001-1500 g. Explanations for the variation in scores and the implications of these findings to the evaluation of low birth weight infants are discussed.
对一组78名出生时体重不足1500克的婴儿进行了前瞻性跟踪研究，以确定出生体重、评估年龄和技能领域对其发育表现的影响。在婴儿6、12、24和36月龄时，使用格里菲斯发育量表对五个技能领域进行了测试。婴儿被分为三个出生体重组：不足750克、750 - 1000克和1001 - 1500克。研究发现年龄和技能之间存在显著的交互作用，其中大动作和手眼协调技能随时间持续下降，而个人社交、听力和语言技能最初下降，然后在12至36月龄时上升。出生体重不足1000克的婴儿的表现始终比出生体重在1001 - 1500克的婴儿差。文中讨论了分数差异的原因以及这些发现对低出生体重婴儿评估的意义。
