To examine the relationship between complementary feeding behaviors (CFB) and anemia for infants and young children in Sichuan, Yunnan and Guizhou province of China.
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 infants and young children between low/moderate/high CFB level groups was compared.
8.0% (273/3 410) of the children were in low CFB level group, and 56.9% (1 940/3 410) 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 average hemoglobin concentration for infants was (119.3 ± 13.8)g/L, and the total anemia rate was 22.4% (765/3 410) . The hemoglobin concentration for infants in urban area ( (123.3 ± 11.3) g/L) was higher than rural area ((115.9 ± 14.8) g/L) (t = 16.75, P < 0.05) and the rate of anemia in urban area (10.5% (165/1 565)) was lower than that in rural area (32.5% (600/1845) ) (χ² = 235.03, P < 0.05) significantly. The rate of anemia was decreased by increasing CFB level(χ² = 73.94, P < 0.05). The rate of anemia in the low CFB level group was the highest (33.7% (92/273) ) while in the high CFB level group was 14.5% (174/1 197), which was the lowest.
The level of complementary feeding behavior for infants and young children in Sichuan, Yunnan and Guizhou province of China is relatively low and their prevalence of anemia is relatively serious. Complementary feeding behavior is closely associated with anemia for infants and young children.
探讨中国四川、云南和贵州三省婴幼儿辅食喂养行为(CFB)与贫血之间的关系。
2011年3月至7月,通过分层随机整群抽样的方法,从四川、云南和贵州三省城乡地区的12个调查点招募了3410名6 - 24个月的儿童,分为3个年龄组(6 - 8个月、9 - 11个月和12 - 24个月)。通过特定问卷收集他们的CFB信息。根据CFB综合评价方法(包括食物制备和选择内容、照料者行为、婴幼儿行为、喂养环境和环境卫生)计算CFB得分,并分为低水平(<总分的60%)、中等水平(总分的60% - 80%)和高水平(>总分的80%)。采集20微升指尖血测量血红蛋白浓度并计算贫血率。比较城乡地区和不同年龄组之间CFB水平分布和贫血率。比较低/中/高CFB水平组婴幼儿贫血率的差异。
8.0%(273/3410)的儿童处于低CFB水平组,中等和高CFB水平组分别为56.9%(1940/3410)和35.1%(1197/3410)。城乡地区CFB水平差异有统计学意义(Z = -21.17,P < 0.05),城市地区高水平比例为53.0%(829/1565),高于农村地区(20.0%(368/1845))。不同年龄组之间CFB水平差异也有统计学意义(H = 43.82,P < 0.05)。高水平比例随年龄增长而降低,6 - 8个月和12 - 24个月分别为41.0%(417/1017)和29.9%(389/1300)。婴幼儿平均血红蛋白浓度为(119.3 ± 13.8)g/L,总贫血率为22.4%(765/3410)。城市地区婴幼儿血红蛋白浓度((123.3 ± 11.3)g/L)高于农村地区((115.9 ± 14.8)g/L)(t = 16.75,P < 0.05),城市地区贫血率(10.5%(165/1565))低于农村地区(32.5%(600/1845))(χ² = 235.03,P < 0.05),差异有统计学意义。贫血率随CFB水平升高而降低(χ² = 73.94,P < 0.05)。低CFB水平组贫血率最高(33.7%(92/273)),高CFB水平组最低(14.5%(174/1197))。
中国四川、云南和贵州三省婴幼儿辅食喂养行为水平较低,贫血患病率较高。婴幼儿辅食喂养行为与贫血密切相关。
