Hospital Practices that Increase Breastfeeding Duration: Results from a Population‐Based Study

ABSTRACT: Background: A high percentage (83%) of mothers in Colorado initiate breastfeeding; but in keeping with national breastfeeding trends, many of them discontinue breastfeeding within the first few months. The objective of this study was to determine the effects of hospital practices on breastfeeding duration and whether the effects differed based on maternal socioeconomic status. Methods: Pregnancy Risk Assessment Monitoring System data were used to calculate breastfeeding duration rates for all Colorado mothers in 2002 to 2003. Breastfeeding duration rates were determined for recipients of each of nine hospital practices included in the survey compared with rates for nonrecipients. Practices that significantly increased breastfeeding duration rates were combined and then stratified by socioeconomic status. Results: Breastfeeding duration was significantly improved when mothers experienced all five specific hospital practices: breastfeeding within the first hour, breastmilk only, infant rooming‐in, no pacifier use, and receipt of a telephone number for use after discharge. Two‐thirds (68%; 95% CI: 61–75) of mothers who experienced all five successful practices were still breastfeeding at 16 weeks compared with one‐half (53%; 95% CI: 49–56) of those who did not. Breastfeeding duration was improved independent of maternal socioeconomic status. Only one in five mothers (18.7%) experienced all five supportive hospital practices. Mothers who experienced the five supportive hospital practices were significantly less likely to stop breastfeeding due to any of the top reasons given for stopping (p < 0.001). Conclusions: Implementation of the five hospital practices supportive of breastfeeding significantly increased breastfeeding duration rates regardless of maternal socioeconomic status.

Birth Centers in Australia: A National Population‐Based Study of Perinatal Mortality Associated with Giving Birth in a Birth Center

ABSTRACT: Background: Perinatal mortality is a rare outcome among babies born at term in developed countries after normal uncomplicated pregnancies; consequently, the numbers involved in large databases of routinely collected statistics provide a meaningful evaluation of these uncommon events. The National Perinatal Data Collection records the place of birth and information on the outcomes of pregnancy and childbirth for all women who give birth each year in Australia. Our objective was to describe the perinatal mortality associated with giving birth in “alongside hospital” birth centers in Australia during 1999 to 2002 using nationally collected data. Methods: This population‐based study included all 1,001,249 women who gave birth in Australia during 1999 to 2002. Of these women, 21,800 (2.18%) gave birth in a birth center. Selected perinatal outcomes (including stillbirths and neonatal deaths) were described for the 4‐year study period separately for first‐time mothers and for women having a second or subsequent birth. A further comparison was made between deaths of low‐risk term babies born in hospitals compared with deaths of term babies born in birth centers. Results: The total perinatal death rate attributed to birth centers was significantly lower than that attributed to hospitals (1.51/1,000 vs 10.03/1,000). The perinatal mortality rate among term births to primiparas in birth centers compared with term births among low‐risk primiparas in hospitals was 1.4 versus 1.9 per 1,000; the perinatal mortality rate among term births to multiparas in birth centers compared with term births among low‐risk multiparas in hospitals was 0.6 versus 1.6 per 1,000. Conclusions: This study using Australian national data showed that the overall rate of perinatal mortality was lower in alongside hospital birth centers than in hospitals irrespective of the mother’s parity.

Psychosocial correlates of exclusive breastfeeding: A systematic review

Background

the World Health Organization recommends that all infants worldwide are exclusively breastfed for the first 6 months of life for optimal health and development. However, very few women worldwide are meeting this recommendation. Psychosocial factors have been identified as potentially modifiable factors implicated in a woman's ability to successfully exclusively breastfeed, however there is very limited research examining these factors specifically for exclusive breastfeeding to 6 months duration.

Methods

a search of psychological, nursing and medical databases was conducted in June 2011 for studies published from 2000 to 2011 examining psychological correlates of exclusive breastfeeding to four to 6 months duration.

Results

nine papers from eight studies were found to be eligible for the review. Psychological factors have been reported to be highly predictive of exclusive breastfeeding outcomes. Research to date shows that psychosocial factors are not only importantly implicated in exclusive breastfeeding duration but they can also be changed through intervention and experiences.

Conclusions

while there is a wealth of literature on the role of psychosocial factors in breastfeeding, there is very limited research specifically examining the role of psychosocial factors of exclusive breastfeeding to 6 months duration. Interpreting the results of the available literature is difficult due to the various methodologies and definitions of exclusive breastfeeding and small sample sizes. Further research, specifically, longitudinal cohort studies are needed which examine psychological determinants of exclusive breastfeeding and infant feeding methods from pregnancy through to 6 months postpartum.     

Impact of Baby‐Friendly Hospital Practices on Breastfeeding in Hong Kong

Abstract: Background: The World Health Organization (WHO) developed the Baby‐Friendly Hospital Initiative to improve hospital maternity care practices that support breastfeeding. In Hong Kong, although no hospitals have yet received the Baby‐Friendly status, efforts have been made to improve breastfeeding support. The aim of this study was to examine the impact of Baby‐Friendly hospital practices on breastfeeding duration. Methods: A sample of 1,242 breastfeeding mother‐infant pairs was recruited from four public hospitals in Hong Kong and followed up prospectively for up to 12 months. The primary outcome variable was defined as breastfeeding for 8 weeks or less. Predictor variables included six Baby‐Friendly practices: breastfeeding initiation within 1 hour of birth, exclusive breastfeeding while in hospital, rooming‐in, breastfeeding on demand, no pacifiers or artificial nipples, and information on breastfeeding support groups provided on discharge. Results: Only 46.6 percent of women breastfed for more than 8 weeks, and only 4.8 percent of mothers experienced all six Baby‐Friendly practices. After controlling for all other Baby‐Friendly practices and possible confounding variables, exclusive breastfeeding while in hospital was protective against early breastfeeding cessation (OR: 0.61; 95% CI: 0.42–0.88). Compared with mothers who experienced all six Baby‐Friendly practices, those who experienced one or fewer Baby‐Friendly practices were almost three times more likely to discontinue breastfeeding (OR: 3.13; 95% CI: 1.41–6.95). Conclusions: Greater exposure to Baby‐Friendly practices would substantially increase new mothers’ chances of breastfeeding beyond 8 weeks postpartum. To further improve maternity care practices in hospitals, institutional and administrative support are required to ensure all mothers receive adequate breastfeeding support in accordance with WHO guidelines.

Admission of Term Infants to Neonatal Intensive Care: A Population‐Based Study

ABSTRACT: Background: Neonatal intensive care and special care nurseries provide a level of care that is both high in cost and low in volume. The aim of our study was to determine the rate of admission of term babies to neonatal intensive care in association with each method of giving birth among low‐risk women. Methods: We examined the records of 1,001,249 women who gave birth in Australia during 1999 to 2002 using data from the National Perinatal Data Collection. Among low‐risk women, we calculated the adjusted odds of admission to neonatal intensive care at term separated for each week of gestational age between 37 and 41 completed weeks. We also calculated the odds of admission to neonatal intensive care in association with cesarean section before or after the onset of labor, and vacuum or instrumental birth compared with unassisted vaginal birth at 40 weeks’ gestation. Results: The overall rate of admission to neonatal intensive care of term babies was 8.9 percent for primiparas and 6.3 percent for multiparas. After a cesarean section before the onset of labor, the adjusted odds of admission among low‐risk primiparas at 37 weeks’ gestation were 12.08 (99% CI 8.64–16.89); at 38 weeks, 7.49 (99% CI 5.54–10.11); and at 39 weeks, 2.80 (99% CI 2.02–3.88). At 41 weeks, the adjusted odds were not significantly higher than those at 40 weeks’ gestation. Among low‐risk multiparas who had a cesarean section before the onset of labor, the adjusted odds of admission to neonatal intensive care at 37 weeks’ gestation were 15.40 (99% CI 12.87–18.43); at 38 weeks, 12.13 (99% CI 10.37–14.19); and at 39 weeks, 5.09 (99% CI 4.31–6.00). At 41 weeks’ gestation, the adjusted odds of admission were significantly lower than those at 40 weeks (AOR 0.64, 99% CI 0.47–0.88). Babies born after any operative method of birth were at increased odds of being admitted to neonatal intensive care compared with those born after unassisted vaginal birth at 40 weeks’ gestation. Conclusions: The adjusted odds of admission to neonatal intensive care for babies of low‐risk women were increased after birth at 37 weeks’ gestation. In a climate of rising cesarean sections, this information is important to women who may be considering elective procedures. (BIRTH 34:4 December 2007)     

Does Postpartum Length of Stay Affect Breastfeeding Duration? A Population‐Based Study

Abstract: Background: Short postpartum hospital stays may leave inadequate time for women to receive assistance with breastfeeding. Women leaving the hospital early may also have household responsibilities that could interfere with breastfeeding. This study examined the relationship between postpartum length of stay and breastfeeding cessation. Methods: This study used data from 10,519 respondents to the California Maternal and Infant Health Assessment (MIHA) surveys from 1999 to 2001. MIHA is an annual statewide stratified random sample, population‐based study of childbearing women in California. Survival analysis was used to examine the relationship between length of stay and length of time breastfeeding. Women were asked about the number of nights their infant stayed in the hospital at birth, whether they breastfed, and if so, the age of the child when they stopped. Hospital stay was defined in three categories: standard (2 nights for a vaginal delivery, 4 nights for a cesarean section), or shorter or longer than the standard stay. Results: Approximately 88 percent of women initiated breastfeeding. Unadjusted predictors of breastfeeding cessation included short or long postpartum stay; young maternal age; Hispanic, African American, or Asian/Pacific Islander race/ethnicity; being unmarried; low income or education level; primiparity; being born in the 50 United States or the District of Columbia; smoking during pregnancy; and low infant birthweight. After adjustment for potential confounders, women with a short stay remained slightly more likely to terminate breastfeeding than women with a standard stay (relative risk, 1.11, 95% confidence interval 1.01, 1.23). Conclusion: Women who leave the hospital earlier than the standard recommended stay are at somewhat increased risk of terminating breastfeeding early. (BIRTH 30:3 September 2003)     

Transfers in Planned Home Births Related to Midwife Availability and Continuity: A Nationwide Population‐Based Study

ABSTRACT: Background: Planning a home birth does not necessarily mean that the birth will take place successfully at home. The object of this study was to describe reasons and risk factors for transfer to hospital during or shortly after a planned home birth. Methods: A nationwide study including all women who had given birth at home in Sweden between January 1, 1992, and July 31, 2005. A total of 735 women had given birth to 1,038 children. One questionnaire for each planned home birth was sent to the women. Of the 1,038 questionnaires, 1,025 were returned. Reasons for transfer and obstetric, socioeconomic, and care‐related risk factors for being transferred were measured using logistic regression. Results: Women were transferred in 12.5 percent of the planned home births. Transfers were more common among primiparas compared with multiparas (relative risk [RR] 2.5; 95% CI 1.8–3.5). Failure to progress and unavailability of the chosen midwife at the onset of labor were the reasons for 46 and 14 percent of transfers, respectively. For primiparas, the risk was four times greater if a midwife other than the one who carried out the prenatal checkups assisted at the birth (RR 4.4; 95% CI 2.1–9.5). A pregnancy exceeding 42 weeks increased the risk of transfer for both primiparas (RR 3.0; 95% CI 1.1–9.4) and multiparas (RR 3.4; 95% CI 1.3–9.0). Conclusions: The most common reasons for transfer to hospital during or shortly after delivery were failure to progress followed by the midwife’s unavailability at the onset of labor. Primiparas whose midwife for checkups during pregnancy was different from the one who assisted at the home birth were at increased risk of being transferred. (BIRTH 35:1 March 2008)
