【medical-news】低出生体重意味着低IQ值

NEW YORK (Reuters Health) - Adolescents with a low birth weight, defined as less than 4.4 lbs., have lower IQ scores than other teens and are also more likely to have movement problems, according to a report in the Archives of Pediatrics and Adolescent Medicine.
The findings support previous reports suggesting that low birth weight is not only a risk factor for major disabilities, such as cerebral palsy and mental retardation, but also for subtler movement and brain impairments.
The findings are based on an analysis of data for 474 low birth weight adolescents who were born in a three-county region during a 3-year period. All of the subjects underwent IQ and movement assessment at home using standard tests.
Movement problems were more common in the study group than in normal comparison subjects, Dr. Agnes H. Whitaker, from Columbia University Medical Center in New York, and colleagues found.
The IQ scores of the low birth weight subjects were within the normal range, but were still significantly lower than population norms, the authors point out.
Further analysis showed that male gender, brain injury seen during newborn ultrasound imaging, and days on a ventilator predicted movement problems. Predictors of lower IQ scores included social disadvantage, poor fetal growth, and brain injury on ultrasound, the report indicates.
"Taken together, these findings suggest that enhanced maternal-fetal and neonatal care have the potential to substantially improve" brain and movement outcomes for low birth weight adolescents, the authors conclude.

纽约（路透通讯社健康部）－根据儿科学和青春期医学研究的一个报道，出生时不到4.4磅的低体重出生的青少年比其同龄人的IQ低，并且有情感障碍。
以前的报道提示低体重出生不仅是残疾的主要危险因素，如大脑性麻痹和智力迟缓发育，而且是精细动作和脑损伤的主要危险因素，这次的发现支持以前的结论。
该发现基于对474个低体重出生青少年的分析，他们是三年期间出生的，来自三个国家。所有的受试对象都用标准的测试进行了IQ和运动评估。
来自纽约哥伦比亚大学医疗中心的Agnes医生和他的同事发现，运动异常在受试群体中比正常对照中更普遍。
作者指出：低出生体重的受试对象的IQ评分在正常范围之间，但是仍然明显低于正常群体。
更深入的分析显示在超声成像的男性新生儿中脑损伤更常见，而且以后就会出现运动障碍。低IQ评分包括社交障碍、低体重和超声显示的脑损伤。
作者得出结论，综合这些发现表明，加强母亲－胎儿和新生儿期护理对低体重出生的青少年脑和运动异常的改善会有潜在的作用。

movement problems是情感障碍吗？
