【摘要】：目的了解农村学龄儿童智力发育现状及其与孕期和现时家庭经济状况的关系,为改善农村学龄儿童营养水平、促进农村儿童智力发育提供参考依据。方法于2013年12月—2014年7月,采用随访队列研究,对2002年参与"中国西部农村新生儿低出生体重的微营养素干预研究"项目人群进行随访,选择2002年12月—2006年1月出生的1 621名儿童及其母亲作为研究对象,主要通过面对面访问的形式调查儿童家庭情况,采用量表测评儿童智力水平。采用相关性分析和公平性分析比较孕期和现时家庭经济状况对儿童智力发育的影响。结果儿童标化后总智商平均得分为(89.9±13.0)分,言语理解、知觉推理、工作记忆和加工速度平均得分分别为(88.1±15.8)(93.2±13.7)(96.0±13.1)(91.3±12.2)分。智力落后儿童孕期家庭经济状况和现时家庭经济状况的集中指数与可信区间分别为-0.178(-0.232~-0.124)和-0.292(-0.346~-0.238),差异有统计学意义;智力高于常人儿童孕期家庭经济状况和现时家庭经济状况的集中指数和可信区间分别为0.278(0.229~0.327)和0.362(0.313~0.411),差异无统计学意义。结论较好的家庭经济状况对儿童智力发育有正向促进作用,且现时经济的影响更大。

By using correlation analysis and analysis of the comparison fair during pregnancy and family economic status influence on children's intelligence development. Children's standard total IQ after the average score was (89.9 + 13), verbal comprehension, perceptual reasoning, work Memory and processing speed in average score was (88.1 + 15.8) (93.2 + 13.7) (96 + 13.1) (91.3 + 12.2). The concentration index of children during pregnancy family economic status and the economic situation of the family mental retardation and confidence intervals were -0.178 (-0.232~-0.124) and -0.292 (-0.346~-0.238), the difference was statistically significant intelligence; concentration index higher than normal children during pregnancy, family economic status and the current economic situation of the family and the confidence intervals were 0.278 (0.229~0.327) and 0.362 (0.313~0.411), the difference was not statistically significant. Conclusion the better family economic conditions have a positive role in promoting the development of children's intelligence, and the impact of the current economy is bigger.
