【目的】 利用Z值法对农村婴幼儿生长发育状况进行评价。 【方法】 采取随机整群抽样的方法对农村 3 91名出生～ 18个月婴幼儿进行调查 ,采用EPI软件进行生长发育Z值的计算 ,SPSS 10 .0软件进行统计分析。 【结果】 随年龄的增长 ,儿童年龄别身长、年龄别体重、身长别体重Z值均有下降的趋势 ,尤在 4～ 6个月后明显 ,在1岁以后又趋于平稳 ;年龄别体重与年龄别身长 (r =0 .64 5 )及身长别体重 (r =0 .5 2 5 )显著正相关。 【结论】 对我国农村儿童应保持和发挥母乳喂养的作用 ,4～ 6月后继续母乳喂养的同时给儿童及时添加量足、质优的辅食 ;采用Z值法对儿童生长发育进行评价简便、明了、易于比较。
【Objective】 The Z value method was used to evaluate the growth and development of infants in rural areas. 【Method】 A random cluster sampling method was used to survey 3 91 infants born 18 months old in rural areas. The EPI software was used to calculate the growth and development Z values, and SPSS 10.0 software was used for statistical analysis. 【Results】 With the increase of age, children’s age, body weight, age-specific body weight, weight-loss Z value all tended to decrease, especially 4 to 6 months after the trend, and stabilized after 1 year old; There was a significant positive correlation between age and body length (r = 0.64 5) and body weight (r = 0.525). 【Conclusion】 In our country, children in rural areas should maintain and play the role of breastfeeding, 4 to 6 months after continued breastfeeding while giving children adequate supplements, high quality food supplement; Z value method for children’s growth and development evaluation is simple, Clear, easy to compare.
