目的:烟台市3~6岁幼儿身体形态的发育情况。方法:2007年5~8月对烟台市城乡861名3~6岁幼儿进行了身体形态(身高、体重、胸围)的测定,把2007年的体质监测的数据与2002年进行比较研究。结果:烟台市3~6岁幼儿的身高城乡差异不大。2002年与2007年的同龄幼儿相比呈上升趋势,但无统计学意义(P>0.05)。城镇幼儿体重平均增长1.8kg,乡村幼儿平均增长1.3 kg,城镇幼儿体重增长明显高于乡村幼儿(P<0.01)。3~6岁幼儿身体充实度有所提高,生长发育良好。结论:烟台市3~6岁幼儿在身体形态方面,如身高、体重和胸围都呈上升趋势,身体生长发育匀称度有较大的改善。经济发展水平、消费水平和饮食结构是城乡幼儿生长发育存在差异的主要原因。
Objective: The body shape of children aged 3 ~ 6 years in Yantai City. Methods: From May to August 2007, 861 children aged 3 ~ 6 years in urban and rural areas of Yantai City were measured for their body shape (height, weight and chest circumference). The 2007 physical fitness monitoring data were compared with those of 2002. Results: The height of children aged 3 ~ 6 in Yantai was not significantly different between urban and rural areas. There was an upward trend in 2002 compared with that of 2007 children of the same age, but no statistical significance (P> 0.05). The average weight gain of young children in urban areas increased by 1.8kg and that of rural children by 1.3kg. The weight gain of young children in urban areas was significantly higher than that of rural children (P <0.01). 3 to 6-year-old children have increased body fullness, good growth and development. Conclusion: The body shape of 3-6-year-old children in Yantai City, such as height, weight, and chest circumference all showed an upward trend, with a significant improvement in the degree of body growth and development. The level of economic development, consumption level and diet structure are the main reasons for the differences in the growth and development of young children in urban and rural areas.
