Of all 908 livebirths weighing less than 1750 g at birth who were born in Scotland in 1984, 896 (99%) were enrolled in a prospective study to document survival and determine the prevalence of neuromotor and sensory impairments and disability. At the age of 4.5 years, 636 (71%) had survived and 611 (96%) were assessed. Overall 16% were disabled; 47 had cerebral palsy (52.5/1000 livebirths), seven were blind (7.8/1000 livebirths), and 11 were deaf and using aids (12.3/1000 livebirths). Among those not overtly disabled, the prevalence of poor neuromotor competence was high and related to birth weight. All growth measures had mean values below the standard population mean indicating a downward shift in the distribution which was related to birth weight. In addition the height distribution was negatively skewed.
在1984年于苏格兰出生的所有908名出生体重低于1750克的活产婴儿中,896名(99%)被纳入一项前瞻性研究,以记录存活情况并确定神经运动和感觉障碍及残疾的患病率。在4.5岁时,636名(71%)存活,611名(96%)接受了评估。总体而言,16%有残疾;47名患有脑瘫(每1000例活产中有52.5例),7名失明(每1000例活产中有7.8例),11名失聪且使用辅助设备(每1000例活产中有12.3例)。在那些没有明显残疾的婴儿中,神经运动能力差的患病率很高,且与出生体重有关。所有生长指标的平均值均低于标准人群平均值,表明分布向下偏移,这与出生体重有关。此外,身高分布呈负偏态。
