目的:探讨早期综合发展指导对儿童体格及智能发育的影响。方法 :2010年1月至2011年12月在我院儿童保健门诊接受早期综合发展指导的0～24个月正常婴幼儿582例作为实验组;分别在6 m,12m,18 m,24 m这4个时段测量头围,身长,体重并检测血清中25-羟维生素D[25-(OH)D]浓度及血红蛋白(Hb)值,同时采用Gesell发育量表测定儿童发育商(developmental quotient,DQ)进行评价幼儿神经系统发育情况。结果:实验组儿童维生素D缺乏,缺铁性贫血发生率小于对照组;实验组儿童除6 m外,其余阶段体格发育(头围、身长、体重)及心理行为发育商(DQ)明显高于对照组。结论:早期综合发展指导不仅改善儿童体格发育,减少营养性疾病的发生,而且促进儿童的神经心理行为发育,开发智能发育潜能。
目的了解单纯性肥胖儿童体内维生素D的水平及干预效果。方法对212例6～12岁单纯性肥胖儿童(肥胖组)和235例体质量指数(BMI)正常儿童(对照组),晨起空腹采集静脉血并采用酶联免疫吸附法(ELISA)检测其血清中25-羟维生素D浓度。对62例BMI异常的维生素D缺乏患儿补充维生素D制剂,1个月后复查25-羟维生素D浓度。结果肥胖组中维生素D不足及缺乏的有140例(66.0%);对照组中维生素D不足及缺乏的有66例(28.1%),两组间差异有统计学意义(P<0.01)。62例维生素D治疗干预者中,维生素D水平达到适宜水平的超重患儿占91.7%(33/36),而肥胖患儿只占65.4%(17/26),两者间差异有统计学意义(P<0.01)。结论单纯性肥胖儿童血清25-(OH)D浓度低于正常儿童,超重儿童补充维生素D制剂的效果较明显。
