目的：研究19915年至2004年澳大利亚社会经济地位与母乳喂养开始和持续时间之间的关系是否发生了变化。设计和设置：澳大利亚统计局在1995年、2001年和2004-05年进行的国家健康调查（NHS）数据的二次分析。社会经济指数的地区（SEIFA）分类被用来作为衡量的socioeconomic status.Main结果measures：母乳喂养的开始率;母乳喂养率在3，6和12 months.Results：1995年和2004-05 NHS之间，母乳喂养的开始和持续时间的整体率变化不大。在2004- 2005年，开始母乳喂养的比例为87.8%，3个月、6个月和12个月母乳喂养的婴儿比例分别为64.4%、50.4%和23.3%。1995年，6个月时母乳喂养的优势比（OR）平均增加了13%（OR，1.13 [95% CI，1.07-1.19]）; 2001年，SEIFA五分位数每增加一次，相对增加21%（OR，121 [95%CI，1.12-1.30]）;而在2004-05年，相对增加了26%（OR，1.26 [95%CI，1.17-1.36]）。3个月和1年的母乳喂养显示出相似的OR变化。母乳喂养initiation.Conclusion的OR变化不大：虽然母乳喂养的整体持续时间在澳大利亚保持相当恒定的1995年和2004-05年之间，差距之间的最不利和最不利的家庭已经扩大了相当多的在此期间。MJA 2008; 189：254-256
Objective: To investigate whether the relationship between socioeconomic status and breastfeeding initiation and duration changed in Australia between 19915 and 2004.Design and setting: Secondary analysis of data from national health surveys (NHSs) conducted by the Australian Bureau of Statistics in 1995, 2001 and 2004-05. The Socio-Economic Indexes for Areas (SEIFA) classification was used as a measure of socioeconomic status.Main outcome measures: Rates of initiation of breastfeeding; rates of breastfeeding at 3, 6 and 12 months.Results: Between the 1995 and 2004-05 NHSs, there was little change in overall rates of breastfeeding initiation and duration. In 2004-05, breastfeeding initiation was 87.8%, and the proportions of infants breastfeeding at 3, 6 and 12 months were 64.4%, 50.4% and 23.3%, respectively. In 1995, the odds ratio (OR) of breastfeeding at 6 months increased by an average of 13% (OR, 1.13 [95% Cl, 1.07-1.19]) for each increase in SEIFA quintile; in 2001, the comparative increase was 21% (OR,121 [95% Cl, 1.12-1.30]); while in 2004-05, the comparative increase was 26% (OR, 1.26 [95% CI, 1.17-1.36]). Breastfeeding at 3 months and 1 year showed similar changes in ORs. There was little change in the ORs for breastfeeding initiation.Conclusion: Although overall duration of breastfeeding remained fairly constant in Australia between 1995 and 2004-05, the gap between the most disadvantaged and least disadvantaged families has widened considerably over this period.
