摘　　要：目的探讨婴幼儿辅食添加频率与生长发育之间的相关性。方法采用分层整群随机抽样选取成都、昆明和贵阳地区3644名6～24月龄健康婴幼儿作为调查对象，通过问巷调查收集婴幼儿母乳、配方奶及辅食添加相关资料，应用辅食添加频率综合评价体系进行量化评分和分级；测量婴幼儿身长和体重并计算z评分以评估生长发育状况；采用Spearman秩相关法分析婴幼儿辅食添加频率与生长发育z评分的相关性，采用线性趋势χ2检验分析婴幼儿辅食添加频率与生长发育不良率的关系。结果城市、农村母乳／配方奶摄入小于3次／天的婴幼儿，辅食添加频率与身长别体重Z评分（WLZ）、年龄别体重Z评分（WAZ）均呈正相关，相关系数城市分别为0．10和0．11（P〈0．05），农村分别为0．20和0．14（P〈0．05）。农村婴幼儿消瘦率随辅食添加频率水平升高而降低。城市、农村母乳／配方奶摄入大于等于3次／天的婴幼儿，辅食添加频率与生长发育Z评分均不存在相关。结论辅食添加频率对婴幼儿生长发育有影响，西南农村地区更为明显，可通过改善婴幼儿辅食添加频率，控制婴幼儿人群的消瘦比例。Objective To study the association between complementary feeding frequency（CFF） and growth of infants and young children. Methods 3644 infants and young children aged 6 - 24 months from Chengdu, Kunming and Guiyang were selected by stratified random cluster sampling. Data on breastfeeding and formula feeding and complementary feeding for children were collected through the questionnaires. Complementary feeding frequency was assessed using a comprehensive evaluation system. Body weight and length for them were measured. Length for age Z-score （LAZ） , weight for age Z-score （WAZ） and weight for length Z-score （WLZ） were calculated. The Spearman rank correlation analysis was used to identify the association between complementary feeding frequency and growth of children. The trend Chi-Square test was used to identify the relationship between complementary feeding frequency and the rate of stunted growth. Results This study indicated that CFF level was significantly positive associated with WLZ and WAZ in the group of breastfeeding and formula feeding less than three times per day in urban and rural groups, correlation coefficients were 0.10 and 0. 11 in urban group and 0.20 and 0.14 in rural group respectively （P 〈 0.05）. Prevalence of wasting reduced with CFF level increasing in rural group. The Z-score did not show significant correlation with CFF level in the group of breastfeeding and formula feeding more than or equal to three times per day in urban and rural groups. Conclusion Complementary feeding frequency is related to growth of infants and young children, especially in rural area of southwest China. The rate of wasting could be controlled by improving complementary feeding frequency of infants and young children.
