Complementary feeding patterns among ethnic groups in rural western China

Objective

This study investigated complementary feeding practices among four ethnic groups (Han, Uygur, Tibetan, and Zhuang) based on a cross-sectional survey in rural western China.

Methods

In 2005, a stratified multistage cluster random sampling method was used to recruit 9712 children (7411 Han, 1032 Uygur, 678 Tibetan, and 591 Zhuang) between 6 and 35 months of age and their mothers from 45 counties in 10 provinces (autonomous regions, municipalities) in western China.

Results

The rates of early introduction (before 6 months) of complementary foods in four ethnic groups (Han, Uygur, Tibetan, and Zhuang) were 71.30%, 95.95%, 82.40%, and 72.30%, respectively. The Infant and Child Feeding Index (ICFI) for Uygur and Tibetan children was lower than that for Han children at all age groups. Uygur children were more likely to have unqualified ICFI compared with Han children in a multivariate logistic regression (odds ratio (OR)=5.138, 95% confidence interval (CI): 4.340–6.084). A higher level of maternal education, greater family wealth, and the availability of complementary feeding educational materials decreased the likelihood of an unqualified ICFI. The nutritional status of children (Han, Tibetan, and Zhuang) with qualified ICFI was better than that for children with unqualified ICFI.

Conclusions

Appropriate interventions are required to improve complementary feeding practices in rural western China.

和谐社会视角下农民养老保障问题研究

社会保障制度是社会的安全网和稳定器,也是构建社会主义和谐社会的重要组成部分.由于我国长期受城乡分割的二元社会保障制度的影响,目前农民养老保障仍然主要依靠传统的家庭养老和土地保障形式.在人口老龄化与工业化、城镇化迅猛发展的今天,传统的保障形式正在遭遇前所未有的挑战.如何应对农民养老风险,解决农民老有所养的问题,是摆在我们面前一个严峻而紧迫的问题.也是二十一世纪我国落实科学发展观,构建社会主义和谐社会必须直面的问题.
