【目的】了解西部45县3岁以下儿童的维生素A普服情况。从社区方面探讨其空间影响因素,为今后相关工作的开展提供有价值的参考。【方法】通过统计描述和比较及秩相关分析法对3岁以下儿童维生素A普服情况及可能的影响指标进行分析。【结果】10个省普服率在52.29%(378/719)到81.29%(239/294)之间,45个县普服率在39.58%(57/144)到91.49%(215/235)之间,其中有20个县普服率不到70%。各省、县间的差异均有统计学意义。秩相关分析结果显示仅有“上年底村人口数”、“上年3岁以下儿童数”与3岁以下儿童的维生素A普服率有负相关。【结论】西部45县3岁以下儿童的维生素A普服率偏低,尚未发现空间距离对儿童维生素A普服率影响。
【Objective】 To understand the general situation of vitamin A in children under 3 years old in 45 western counties. To explore the spatial influencing factors from the community and provide valuable reference for the future work. 【Methods】 By means of statistical description and comparison and rank correlation analysis, the general situation of vitamin A in children under 3 years old and possible influence index were analyzed. 【Results】 The rates of general service in 10 provinces ranged from 52.29% (378/719) to 81.29% (239/294). The prevalence rate of general service in 45 counties ranged from 39.58% (57/144) to 91.49% (215/235) Among them, there are 20 county general service rate of less than 70%. The differences among provinces and counties were statistically significant. Rank correlation analysis showed that there was only negative correlation between the number of villagers at the end of last year and the number of children under 3 in the previous year and the prevalence of vitamin A in children under 3 years old. 【Conclusion】 The prevalence of vitamin A in children under 3 years of age in the 45 western counties is relatively low. The effect of spatial distance on the prevalence of vitamin A in children has not been found.
