Cropley L, Herwehe JC. Evaluation of institutional support for breastfeeding among low-income women in the metropolitan New Orleans area. J Am Diet Assoc. 2002 Jan; 102(1): 94-96.PubMed ID: 11794510
To explore institutional support for breastfeeding among low-income women in the metropolitan New Orleans area.
Hospitals in the New Orleans area that provided obstetrical services.
Hospitals in the New Orleans are that did not provide obstetrical services.
The ten hospitals that offered maternity services and care for newborns in the metropolitan New Orleans area were asked by phone to complete the study questionnaire. Key participants were lactation consultants of head nurses in obstetrics departments of the hospitals, who identified through the use of hospital directories and a list provided by the Louisiana Lactation Consultants Association.
- After verbal consent to participate in the study, the self-administered questionnaire was hand delivered
- Questionnaire adapted from the WHO/UNICEF Checklist for Evaluating the Adequacy of Support for Breast Feeding in Maternity Hospitals, Wards and Clinics. Information was collected on:
- Breastfeeding policies
- Staff training
- Health education
- Discharge procedures
- Delivering mothers' demographics
- It also allowed respondents to provide their views on breastfeeding barriers and key elements of successful promotion efforts.
- SPSS 9.0 for Windows, 1999, Chicago, IL was used for Spearman's correlation coefficients and a partial correlation
- Because this study used aggregate hospital data, the researchers could not control for income or site of delivery to isolate specific effects of hospital policy.
- Breastfeeding policies
- Staff training
- Health education
- Discharge procedures
- Delivering mother's demographics.
10 hospitals were asked to participate.
Attrition (Final N)
- Nine hospitals participated
- One hospital was excluded from the analysis because of missing data on patient ethnicity.
New Orleans, Louisiana.
- Responding hospitals reported deliveries ranging between 400 to 2,000 births per year, with an average of 1,122 births per year
- The percentage of low-income patients who were recipients of Medicaid or Special Supplemental Nutrition Program for Women, Infants and Children, or by income level, ranged from 6% to 90%, with an average of 47%.
- The percentage of women who initiated breastfeeding after delivery ranged from 20% to 75%. Only one facility met the Healthy People 2010 objective of 75% of mothers who breastfeed their babies in the early post-partum period.
- A negative correlation was found between breastfeeding rates and income level (P<0.01). The negative association maintained significance when a partial correlation between rates of breastfeeding and income level, controlling for African American ethnicity, was performed (P<0.05).
- A negative correlation was also found between African American ethnicity and breast feeding (P=0.08).
- The majority (N=6) of facilities had explicit policies for promoting and supporting breastfeeding
- Almost all facilities (N=8) provided specialized training in lactation management to staff members
- Most facilities (N=7) had at least one designated staff member, either lactation consultant or nurse with specialized training in lactation management, available full-time to advise mothers.
- Eight facilities had policies allowing babies to stay in the rooms with their mothers. The respondent at the facility lacking such a policy reported, "Babies in room anyway."
- Seven facilities allowed mothers to have their babies with them in their beds. One respondent from a facility where mothers were not allowed to have their babies with them reported, "They did it anyhow."
- Eight facilities have policies to restrict an infant's feeding before the establishment of breastfeeding; staff interpretation of this policy at three different facilities resulted in food and drink being given to the newborns
- Only five respondents reported that data are collected on the prevalence of breastfeeding initiation and breastfeeding at the time of discharge. Even fewer reported a system in place for assessing effectiveness of health care practices and educational materials specific to breastfeeding.
Health and Education
- All respondents reported that breastfeeding education covered lactation physiology, how to maintain lactation, prevention and management of common problems and sources of support for problems post-discharge
- Eight respondents reported that expectant mothers were usually advised about nutritional requirements during pregnancy and lactation and on dangers associated with substance abuse and breastfeeding
- All reported that support and counseling on initiation and maintenance of breastfeeding were routinely provided for women who experienced a cesarean or premature birth, delivered a low birth weight infant or had an infant in a special care unit
- All reported that breastfeeding mothers were provided with printed educational materials. It was unknown if the education sessions or the print materials were relevant and appropriate to the target population.
- Six facilities had a specific policy to give breastfeeding mothers special discharge packs
- Where facilities provided "discharge packs" containing formula, bottles, nipples and pacifiers, two respondents reported that anything unrelated to breastfeeding was removed and that packs were "not routinely" distributed to breastfeeding mothers
- Six facilities provided breast pump rental on a sliding scale fee.
Hospital facilities need to evaluate existing breastfeeding policies for consistency of interpretation and implementation. Furthermore, if no policy exists, one needs to be created.

I feel this would have been a stronger study if it was conducted as a chart review as opposed to a survey completed by one person representing the entire department.
