社会经济地位
Socioeconomic status of mothers likely has a larger influence on breastfeeding adherence than race or ethnicity, as many women who are members of groups with low breastfeeding rates also have a low socioeconomic status. Among women born in the United States, women who are wealthier are more likely to breastfeed. In addition, employment can influence the decision to breastfeed. When either parent was unemployed or held a lower-status occupation (such as labor or sales), their children were more likely to never have been breastfed. In addition, women with public insurance or with no health insurance are more likely to never have breastfed their children, as are women who receive WIC.
