中国西部两县6~36月龄婴幼儿喂养指数与生长发育的多重对应分析
Correlation between feeding index and growth development of 6 -36 month-old infants in two counties of western China by applying multiple correspondence analysis
摘要
Abstract
Objective: To explore the correlation between feeding index and growth development status of infants from two counties of western China by applying the method of multiple correspondence analysis. Methods: Two sample counties were randomly selected from the ones that satisfied the research conditions in Shaanxi province and Chongqing in western China. In the study, 472 premature/low birth weight infants (PLBW) and 461 normal term infants (NT) of 6 -36 months from the two counties were investigated from September 2010 to November 2010. The SPSS 19. 0 software was applied to analyze the data using general statistical analysis and multiple correspondence analysis. Results; In the two counties of western China, the proportion of infants with feeding index at the medium level was the highest, which was between 50% and 60% . In the PLBW group and the NT group, the proportion of low level of feeding index among 6 -9 month-old infants was the highest, and the proportion was 33.3% for the PLBW group and 29.4% for the NT group. For both the PLBW group and the NT group, the distribution of feeding index among the different age groups showed significant difference (P < 0.05 ) . Among the infants with low level of feeding index, the growth development of the PLBW lay behind that of the NT. We could see a catching-up trend of the PLBW with medium or good level of feeding index, but their growth development index was still at a lower level than that of the NT with the same level of feeding condition. Through multiple correspondence analyses, the outcomes of PLBW corresponded and strongly correlated with low level of feeding index, low level of growth development index, mother' s low education degree and low annual family income. And the outcomes of NT corresponded and strongly correlated with medium/good level of feeding index, medium level of growth development status, mother' s medium/high education degree and medium/high level of annual family income. Conclusion: There are good correspondence correlations at different hierarchical levels of the infants' group, feeding index, growth development index and family factors in the two counties of western China. Multiple correspondence analysis could directly reveal the correlation among several variables, which is a suitable method for categorical data. The result can be illustrated directly through a two-dimensional graph and could provide the suggestion of feeding practice for different infants in western rural China.关键词
