An Intergenerational Exploration of Breastfeeding Journeys Through the Lens of African American Mothers and Grandmothers

Do maternal grandmothers influence breastfeeding duration and infant nutrition? Evidence from Merida, Mexico

OBJECTIVES

Breast-feeding is sensitive to somatic, hormonal, behavioral and psychological components of maternal capital. However, through grandmothering, older women may also influence breast-feeding by transferring informational resources to their daughters. We hypothesized that mothers with prolonged instrumental support from their own mother are more likely to have received advice and to have favorable attitudes/practices regarding breastfeeding, compared to those lacking such support, with implications for the grandchild's somatic capital.

METHODS

We recruited 90 mother-infant dyads (52 with grandmaternal support, 38 without) in Merida, Yucatan, Mexico. All children were first-borns, aged ~2 years. Anthropometry and body composition were assessed. Data on grandmother's breastfeeding advice and maternal breastfeeding duration were obtained by questionnaire. Maternal attitudes to breast-feeding were assessed using the Iowa Infant Feeding Attitude Scale.

RESULTS

Women with instrumental support were more likely to have received grandmaternal advice during pregnancy/infancy on exclusive breast-feeding duration (60% vs. 37%, p = 0.033) and the type of first complementary food (81% vs. 47%, p = 0.001). However, women with support had a less favorable attitude to breastfeeding than those without and breastfed their children for less time (median 5 vs. 10.5 months, p = 0.01). No group differences were found in children's length, weight, skinfolds or lean mass z-score.

DISCUSSION

Although grandmothers providing instrumental support provided advice regarding breastfeeding, their attitudes may reflect issues beyond nutritional health. Advice of maternal grandmothers did not promote extended breastfeeding, however the differences in breastfeeding attitudes were not associated with the children's nutritional status. Grandmothers should be included in public health interventions promoting breastfeeding.

Examination of Factors That Contribute to Breastfeeding Disparities and Inequities for Black Women in the US

Breastmilk is considered the optimal nutrition for newborns. US Black women continue to have the lowest breastfeeding initiation and duration rates. This Perspective examines factors associated with breastfeeding disparities and inequities among Black women through the lens of critical race theory and the social-ecological model. Recommendations to increase breastfeeding rates in this population include increased communication and educational strategies by health care professionals, education to recognize implicit bias and systemic racism in our health care system, early prenatal and ongoing postpartum breastfeeding support, increased community support, and breastfeeding groups developed by and for Black women. In addition, equity policies such as paid maternity leave and work policies that support milk expression would provide needed institutional support for women in the workplace.
