摘　　要：目的 探讨云南、贵州、四川省婴幼儿辅食喂养行为与贫血的关系.方法 于2011年3-7月采用分层整群随机抽样方法,以云南、贵州、四川省所有城区的妇幼保健机构儿保门诊和农村的乡镇卫生院作为调查点,共12个,在每个调查点分6～8、9～11和12～24月龄组进行抽样,共抽取6 ～ 24月龄健康婴幼儿3 410名作为研究对象.采用问卷调查收集婴幼儿辅食喂养行为信息（包括食物制备和选择、喂养人行为、婴幼儿行为、喂养环境及环境卫生）,参照辅食喂养行为综合评价体系对婴幼儿辅食喂养行为合理程度进行量化评分,按照其总分占其满分的百分比进行分组：总分占满分的百分比＜60％为婴幼儿辅食喂养行为低水平组,60％ ～ 80％为中水平组,＞80％为高水平组.抽取调查婴幼儿指尖血20μl,测定血红蛋白含量,并诊断其是否患有贫血.分析城乡及不同月龄组间婴幼儿辅食喂养行为水平的分布情况、血红蛋白含量及贫血患病率的差异;比较不同辅食喂养水平婴幼儿贫血率的差异.结果 云南、贵州、四川省婴幼儿辅食喂养行为处于低、中、高水平的比例分别为8.0％ （273/3 410）、56.9％（1 940/3 410）、35.1％（1 197/3 410）;城乡间喂养行为水平的分布差异有统计学意义（Z=-21.17,P＜O.05）,其中城市高水平比例为53.0％ （829/1 565）,高于农村[20.0％（368/1 845）];不同月龄组间差异有统计学意义（H =43.82,P＜0.05）,其中喂养行为处于高水平的比例随月龄增加呈下降趋势,6～8月龄最高[41.0％（417/1017）],12 ～ 24月龄最低[29.9％（389/1 300）].婴幼儿血红蛋白含量为（119.3±13.8）g/L,总贫血率为22.4％（765/3 410）.其中城市婴幼儿血红蛋白含量为（123.3±11.3）g/L,高于农村[（115.9±14.8）g/L]（t=16.75,P＜0.05）;城市婴幼儿贫血率为10.5％（165/1 565）,低于农村[32.5％ （600/1 845）]（x2=235.03,P＜0.05）.贫血率�Objective To examine the relationship between complementary feeding behaviors （CFB） and anemia for infants and young children in Sichuan,Yunnan and Guizhou province of China.Methods A total 3 410 children aged 6-24 months were recruited from 12 survey sites in the urban and rural areas of Sichuan,Yunnan and Guizhou provinces by stratified random cluster sampling in 3 age groups （6-8 months,9-11 months and 12-24 months） from March to July in 2011.The information of CFB for them was collected through a specific questionnaire.According to the comprehensive evaluation method of CFB（including content of food preparation and selection,caregivers＇ behavior,infants＇ behavior,feeding environment and environmental hygiene）,the scores of CFB were calculated and grouped as low（＜ 60％ of total score）,moderate（60％-80％ of total score） and high level（＞ 80％ of total score）.Twenty microliter of fingertip blood was extracted to measure the hemoglobin concentration and anemia rate was calculated.Distribution of CFB level and rate of anemia were compared between urban/rural areas and different age groups.Difference of anemia rate for inffants and young children between low/moderate/high CFB level groups was compared.Results 8.0％ （273/3 410）of the children were in low CFB level group,and 56.9％ （1 940/3410） and 35.1％ （1 197/3 410） in moderate and high CFB level group respectively.The difference of CFB levels between urban and rural areas was significant （Z =-21.17,P ＜0.05）,the proportion of high level in urban area was 53.0％ （829/1 565）,which was higher than that in rural area（20.0％ （368/1845））.The difference of CFB levels between different age groups was also significant （H =43.82,P ＜ 0.05）.The proportion of high level decreased by increasing age,which was 41.0％ （417/1 017）and 29.9％ （389/1 300）in 6-8 months and 12-24 months respectively.The averagehemoglobin concentration for infants was （119.3 ± 13.8） g/L,and the total anemia rate wa
