The objective of this study was to investigate knowledge and community perceptions of breastfeeding in Western Australia using a factor analysis approach.
Data were pooled from five Nutrition Monitoring Survey Series which included information on breastfeeding from 4,802 Western Australian adults aged 18-64 years. Tetrachoric factor analysis was conducted for data reduction and significant associations identified using logistic, ordinal and poisson regression analyses.
Four factors were derived for benefits (it's natural, good nutrition, good for the baby, and convenience), barriers (breastfeeding problems, poor community acceptability, having to go back to work, and inconvenience) and for enablers (breastfeeding education, community support, family support and not having to work). As assessed by standardized odds ratios the most important covariates across benefit factors were: importance of breastfeeding (ORs range from 1.22-1.44), female gender (ORs range from 0.80 to 1.46), being able to give a time for how long a baby should be breastfed (ORs range from 0.96 to 1.27) and education (less than high school to university completion) (ORs range from 0.95 to 1.23); the most important covariate across barrier factors was being able to give a time for how long a baby should be breastfed (ORs range from 0.89 to 1.93); and the most important covariates across all enabling factors were education (ORs range from 1.14 to 1.32) and being able to give a time for how long a baby should be breastfed (ORs range from 1.17 to 1.42).
Being female, rating breastfeeding as important, believing that babies should be breastfed for a period of time and education accounted for most of the statistically significant associations. The differences between male and female perceptions require investigation particularly in relation to returning to work.
本研究的目的是采用因子分析方法调查西澳大利亚州关于母乳喂养的知识和社区认知情况。
数据来自五个营养监测调查系列，其中包括4802名年龄在18 - 64岁的西澳大利亚州成年人的母乳喂养信息。进行四分相关因子分析以进行数据简化，并使用逻辑回归、有序回归和泊松回归分析确定显著关联。
得出了关于益处（自然、营养良好、对婴儿有益、方便）、障碍（母乳喂养问题、社区接受度低、必须回去工作、不便）和促进因素（母乳喂养教育、社区支持、家庭支持、无需工作）的四个因子。通过标准化优势比评估，益处因子中最重要的协变量为：母乳喂养的重要性（优势比范围为1.22 - 1.44）、女性性别（优势比范围为0.80至1.46）、能够说出婴儿应母乳喂养的时长（优势比范围为0.96至1.27）以及教育程度（从高中以下到大学毕业）（优势比范围为0.95至1.23）；障碍因子中最重要的协变量是能够说出婴儿应母乳喂养的时长（优势比范围为0.89至1.93）；所有促进因素中最重要的协变量是教育程度（优势比范围为1.14至1.32）和能够说出婴儿应母乳喂养的时长（优势比范围为1.17至1.42）。
女性性别、将母乳喂养视为重要、认为婴儿应母乳喂养一段时间以及教育程度占了大多数具有统计学意义的关联。男女认知之间的差异需要进行调查，特别是与重返工作相关的差异。
