我们对重庆市巴南区鱼洞镇194名0～3岁儿童进行定期体格检查。根据九城区“正常儿童体格发育的衡量数字”和体格发育五等级的评价为标准进行评价。其中达均值74人,占总人数的38％。分析原因:1.重庆地区环境对儿童生长发育的影响较为明显。重庆气候多雨多雾,紫外线的照射不足,造成小儿的维生素D在体内的合成较少,这是影响重庆地区小儿身高达不到标准的主要原因。2.喂养不当。多数是以牛乳和米糊喂养,小儿容易造成腹泻。3.营养不够,也是造成小儿偏矮的重要原因。我们采取的对策为:①提倡母乳喂养,及时添加辅食;②小儿的户外活动时间要保证,每天应达2小时以上;③加强小儿体育锻炼,帮助小儿做被动操,跳跃,跑动。 We conducted regular physical examinations of 194 children aged 0-3 years in Yudong, Banan District, Chongqing. According to Ninetowns “normal children’s physical development of the measure” and the physical development of five levels of evaluation as the standard evaluation. The average of 74 people, accounting for 38% of the total number. Analysis of the reasons: 1. Chongqing environmental impact on children’s growth and development is more obvious. Chongqing weather rainy and foggy, inadequate exposure to ultraviolet radiation, resulting in the synthesis of vitamin D in children less, which is affecting the height of children in Chongqing reach the standard height of the main reasons. 2. Improper feeding. Most are fed with milk and rice, children easily cause diarrhea. 3 nutrition is not enough, but also caused an important reason for short children. We take the following countermeasures: ① promote breastfeeding, add complementary food in time; ② children’s outdoor activities to ensure that the daily should be up to 2 hours or more; ③ strengthen children’s physical exercise to help children do passive manipulation, jumping, running.
