The authors assessed 137 VLBW children and 162 controls for laterality by observation and questionnaire at 12 years of age. A significantly higher proportion of the VLBW children were either left-handed or mixed-handed. A number of motor cognitive and educational outcome variables were measured. Impaired manual dexterity was found to be significantly more common in VLBW non-right-handers. This group was also found to be more at risk of poor near vision. No cognitive or educational outcomes were associated with handedness. The results seem to support the theory that at least in a proportion of VLBW children, non-right-handedness has a pathological basis, but the relationship to perinatal events remains obscure.
作者在137名极低出生体重儿和162名对照儿童12岁时，通过观察和问卷调查评估其利手情况。极低出生体重儿中左利手或混合利手的比例显著更高。测量了一些运动、认知和教育方面的结果变量。结果发现，在极低出生体重儿的非右利手者中，手部灵活性受损明显更为常见。还发现这一群体近视的风险更高。未发现认知或教育结果与利手有关。这些结果似乎支持了这样一种理论，即至少在一部分极低出生体重儿中，非右利手有病理基础，但与围产期事件的关系仍不清楚。
