Incidence and correlates of breast-feeding in socioeconomically disadvantaged women.

Although the incidence of breast-feeding has more than doubled in the United States in recent years, this increase has been less evident among blacks and in lower socioeconomic groups. To understand better this lower incidence, cognitive and personality correlates of breast-feeding were examined in two independent lower-class samples: 137 black inner-city mothers and 50 predominantly white mothers. Ego development, depression, and verbal competence were assessed during the first postpartum year. Only 21.9% of the black sample chose to breast-feed, in contrast with 58.0% of the white sample. Although unrelated to depression and social support, breast-feeding was positively associated with ego level and cognitive ability in both samples. Cognitive ability was assessed using the Peabody Picture Vocabulary Test-Revised, which was found to be valid in relation to maternal and infant characteristics for the black socially disadvantaged sample. When compared using multiple regression analysis, the relation of ego maturity to breast-feeding was generally stronger than that of cognitive ability. Women with more ego maturity may breast-feed because of increased feelings of empathy or nurturance or because they are more attuned to current health advisories and able to deviate from community norms to adopt breast-feeding practices more characteristic of the white middle class.

Effect of maternal social support on attachment: experimental evidence.

The present study used an experimental format to evaluate the influence of maternal social support on the development of attachment. 46 WIC primigravidas were randomly assigned to an experimental or control condition. Volunteer coaches, trained to provide maternal support and information, met with experimentals prenatally and during the first postpartum year. Experimentals and controls did not differ on demographics, ego level, verbal ability, affect, or perceived social support. At 14 months, experimental infants scored higher on an Attachment Ratings cluster from Waters and Deane's new Q-sort procedure. This cluster was more sensitive than a Criterion Sort measure in detecting the effect of the manipulation and as or more sensitive to maternal affect, perceived support, and the HOME. These findings provide experimental evidence regarding the importance of social support on infant attachment and support for an alternative approach for reducing data from the attachment Q-sort.
