Expanding breastfeeding promotion and support in the Special Supplemental Nutrition Program for Women, Infants and Children (WIC)

Predictors of breastfeeding exclusivity in a WIC sample

OBJECTIVE

To examine predictors of breastfeeding exclusivity in low-income women who received services from a Chicago area clinic of the Special Supplemental Nutrition Program for Women, Infants and Children Program (WIC).

DESIGN

A secondary data analysis of existing clinical and administrative data.

SETTING

An urban community health center serving low-income families.

PARTICIPANTS

Two hundred and thirty-five (235) low-income women who initiated breastfeeding and received WIC services.

METHODS

Logistic regression models were fit to existing prenatal and postpartum data to determine predictors of breastfeeding exclusivity during the immediate postpartum period.

RESULTS

Only 23% of the sample breastfed exclusively. Women who received first-trimester prenatal care were more likely to exclusively breastfeed than women who entered prenatal care in later trimesters (OR = 2.02, p ≤ 0.05). Women who declared intentions prenatally to exclusively breastfeed were more likely to exclusively breastfeed than women who did not intend to breastfeed (OR = 3.85, p ≤ 0.001). Overweight/obese women were less likely to exclusively breastfeed than normal/underweight women (OR = 0.50, p ≤ 0.05).

CONCLUSION

Findings from this study can be used to develop tailored interventions to promote breastfeeding exclusivity among low-income WIC recipients.

Breastfeeding rates in the United States by characteristics of the child, mother, or family: the 2002 National Immunization Survey

OBJECTIVE

In the third quarter of 2001, the National Immunization Survey (NIS) began collecting data on the initiation and duration of breastfeeding and whether it was the exclusive method of infant feeding. Using the data from the 2002 NIS, this study estimates breastfeeding rates in the United States by characteristics of the child, mother, or family.

METHODS

The NIS uses random-digit dialing to survey households nationwide with children 19 to 35 months old about vaccinations and then validates the information through a mail survey of the health care providers who gave the vaccinations. In 2002, approximately 3500 households from the NIS were randomized to 1 of the 3 rotating topical modules that covered breastfeeding.

RESULTS

More than two thirds (71.4%) of the children had ever been breastfed. At 3 months, 42.5% of infants were exclusively breastfed, and 51.5% were breastfed to some extent. At 6 months, these rates dropped to 13.3% and 35.1%, respectively. At 1 year, 16.1% of infants were receiving some breast milk. Non-Hispanic black children had the lowest breastfeeding rates. Breastfeeding rates also varied by participation in day care or the Women, Infants, and Children program, socioeconomic status, and geographic area of residence.

CONCLUSIONS

Although the rate of breastfeeding initiation in the United States is near the national goal of 75%, at 6 and 12 months postpartum the rates of breastfeeding duration are still considerably below the national goals of 50% and 25%, respectively. In addition, rates of exclusive breastfeeding are low. Strenuous public health efforts are needed to improve breastfeeding behaviors, particularly among non-Hispanic black women and socioeconomically disadvantaged groups.
