【摘要】 目的:了解2009~2011年上海市已婚育龄妇女口服避孕药(OC)使用率和区县分布情况以及与OC使用率相关的区县社会环境因素。方法:资料来自2009~2011年上海市已婚育龄妇女抽样调查以及市人口计生委公开发布的各区县人口和计划生育服务站分布资料。采用一般描述性分析、单因素卡方检验分析OC使用率以及用多水平logistic回归模型分析区县水平社会环境影响因素。结果:2009~2011年上海市已婚育龄妇女OC使用率分别为3.35%、3.26%、2.85%,呈小幅下降趋势。生育率较低的区县OC使用率最高(3.93%~4.54%),经济文化水平中等或以上区县OC使用率较低(3%)。近3年来,中等经济文化水平区县OC使用率下降趋势明显。多水平模型分析表明,文化水平中等(OR=0.44,95%CI=0.25~0.76)或较高(OR=0.44,95%CI=0.39~0.50)的区县OC使用率显著低于水平较低的区县;计划生育服务站平均服务人口数>1万的区县中,已婚育龄妇女使用OC的几率是平均服务人口数<1万区县的1.4~1.6倍;调查对象经济水平与OC使用率无关。结论:上海市已婚育龄妇女OC使用率较低且逐年下降,教育水平相对较低的区县使用率高。更多还原

【Abstract】 Objective: To explore the prevalence of oral contraceptive( OC) use overall in Shanghai and among districts within the municipality,and to explore district-level social-environmental determinants of OC use among married women of childbearing age in Shanghai. Methods: Data for this study were from annual family planning surveys among married women of childbearing age in Shanghai between 2009 and 2011 and the annual report of population and family planning published by Shanghai Population and Family Planning Committee in respective year. Prevalence and district-level determinants of OC use were analyzed and reported in this study. Descriptive analysis,Chi-square test and multi-level logistic regression were used for dada analyses. Results: The prevalence of OC among married women of childbearing age in Shanghai slightly declined from3. 35% in 2009 to 3. 26% in 2010 and further to 2. 85% in 2011. Districts / countries where fertility was low had significantly higher prevalence of OC use( 3. 93%-4. 54%) than their counterparts( around 3%). The prevalence of OC use at districts / counties where educational or economic status was at middle or above level followed a decline trend between 2009 and2011. After controlling for potential confounding by using multilevel logistic regression,the probability of OC use was significantly lower at districts / counties where educational level was classified as middle( odd ratio: 0. 44,95% CI: 0. 25-0. 76) or high( odd ratio: 0. 44,95% CI: 0. 39-0. 50) than those where the level was low. At districts / countries where the average population size that one family planning station served was over 10 thousand,the likelihood of OC use was 1. 4-1. 6 times higher than their counterparts. District-level economic development indicator was no longer associated with the likelihood of OC use in multilevel analysis. Conclusion: The prevalence of OC use among married women of childbearing age in Shanghai is low and declined between 2009 and 2011. OC use is less common at backward districts / countries in education than their counterparts.更多还原
