BACKGROUND
The objective of this study was to determine the relationship between the quality of feeding practices and children's nutritional status in rural western China.
METHODS
A sample of 12,146 pairs of 6- to 35-month-old children and their mothers were recruited using stratified multistage cluster random sampling in rural western China. Quantile regression was used to analyze the relationship between the Infant and Child Feeding Index (ICFI) and children's nutritional status.
RESULTS
In rural western China, 24.37% of all infants and young children suffer from malnutrition. Of this total, 19.57%, 8.74% and 4.63% of infants and children are classified as stunting, underweight and wasting, respectively. After adjusting for covariates, the quantile regression results suggested that qualified ICFI (ICFI > 13.8) was associated with all length and HAZ quantiles (P<0.05) and had a greater effect on the following: poor length and HAZ, the β-estimates (length) from 0.76 cm (95% CI: 0.53 to 0.99 cm) to 0.34 cm (95% CI: 0.09 to 0.59 cm) and the β-estimates (HAZ) from 0.17 (95% CI: 0.10 to 0.24) to 0.11 (95% CI: 0.04 to 0.19). Qualified ICFI was also associated with most weight quantiles (P<0.05 except the 80th and 90th quantiles) and poor and intermediate WAZ quantiles (P<0.05 including the 10th, 20th 30th and 40th quantiles). Additionally, qualified ICFI had a greater effect on poor weight and WAZ quantiles in which the β-estimates (weight) were from 0.20 kg (95% CI: 0.14 to 0.26 kg) to 0.06 kg (95% CI: 0.00 to 0.12 kg) and the β-estimates (WAZ) were from 0.14 (95% CI: 0.08 to 0.21) to 0.05 (95% CI: 0.01 to 0.10).
CONCLUSIONS
Feeding practices were associated with the physical development of infants and young children, and proper feeding practices had a greater effect on poor physical development in infants and young children. For mothers in rural western China, proper guidelines and messaging on complementary feeding practices are necessary.
背景
本研究的目的是确定中国西部农村地区喂养方式质量与儿童营养状况之间的关系。
方法
采用分层多阶段整群随机抽样方法，在中国西部农村地区招募了12146对6至35个月大的儿童及其母亲。采用分位数回归分析婴幼儿喂养指数（ICFI）与儿童营养状况之间的关系。
结果
在中国西部农村地区，所有婴幼儿中有24.37%营养不良。其中，19.57%、8.74%和4.63%的婴幼儿分别被归类为发育迟缓、体重不足和消瘦。在对协变量进行调整后，分位数回归结果表明，合格的ICFI（ICFI>13.8）与所有身长和身高别年龄（HAZ）分位数相关（P<0.05），并且对以下方面有更大影响：身长和HAZ较差的情况，β估计值（身长）从0.76厘米（95%CI：0.53至0.99厘米）到0.34厘米（95%CI：0.09至0.59厘米），β估计值（HAZ）从0.17（95%CI：0.10至0.24）到0.11（95%CI：0.04至0.19）。合格的ICFI还与大多数体重分位数相关（除第80和90百分位数外，P<0.05）以及体重别年龄（WAZ）较差和中等的分位数相关（P<0.05，包括第10、20、30和40百分位数）。此外，合格的ICFI对体重和WAZ较差的分位数有更大影响，其中β估计值（体重）从0.20千克（95%CI：0.14至0.26千克）到0.06千克（95%CI：0.00至0.12千克），β估计值（WAZ）从0.14（95%CI：0.08至0.21）到0.05（95%CI：0.01至0.10）。
结论
喂养方式与婴幼儿的身体发育相关，适当的喂养方式对婴幼儿较差的身体发育有更大影响。对于中国西部农村地区的母亲来说，关于辅食喂养方式的适当指导和信息是必要的。
