【摘要】 目的探讨低出生体质量对儿童认知能力和行为发育的影响。方法采用Bayley婴幼儿发育量表(BSID)、2~3岁Achenbach儿童行为量表(CBCL)和自编家庭一般环境问卷对50名2~3岁低出生体质量(LBW)儿童和380名正常出生体质量(NBW)儿童进行发育智商评定和行为问题调查。结果LBW组的智力发育指数(MDI)和运动发育指数(PDI)分别为(97.4±20.2)和(99.8±16.3),显著低于NBW组(P<0.01,0.05),LBW组MDI<85分者的比例为20%,显著高于NBW组的2%(P<0.01)。②LBW组行为问题发生率为24%,NBW组为14.21%,LBW组社交退缩的发生率为8%高于NBW组儿童,差异有显著性(P=0.02,),而NBW组儿童的睡眠障碍分[(2.74±2.50)分]高于LBW组[(2.10±1.85)分],差异有显著性(P=0.031)。结论2~3岁LBW儿童的认知水平低于NBW儿童,易发生行为异常。更多还原

【Abstract】 ObjectiveTo explore the cognitive and behavioral development in low birth weight children aged 2~3. Methods50 low birth weight (LBW) children and 380 normal birth weight (NBW) children were investigated and assessed by Achenbach’s Children Behavior Checklist and Bayley Scales of Infant Development. Outcomes of these toddlers were also assessed with a self-made questionnaire of influential factors. Results①LBW children were more likely to have lower mean MDI(97.4±20.2 vs 106.3±12.7) and lower mean PDI( 99.8 ±16.3 vs 104.8±7.5) than NBW children. The proportion of LBW children whose MDI score lower than 85 was 20% and this proportion is higher than that of NBW children( P <0.01). ②The prevalence of behavior problems was 24% in LBW children and 14.21% in NBW children. The rate of social withdraw was 8% in LBW children and it is higher than that of NBW children ( P =0.02).Independent t-tests identified that NBW children had more scores of sleep problems(2.74±2.50 vs 2.10±1.85) than LBW children( P =0.031). ConclusionLBW Children were less cognitive ability than NBW children and they had high prevalence of behavior problems.更多还原
