The effectiveness of primary care-based interventions to promote breastfeeding: systematic evidence review and meta-analysis for the US Preventive Services Task Force

Reasons for in-hospital formula supplementation of breastfed infants from low-income families

In-hospital formula supplementation of breastfed infants negatively impacts breastfeeding duration. Infants from low-income families have some of the lowest exclusive breastfeeding rates in the United States. The objectives of this study were to identify (1) reasons low-income breastfeeding mothers begin in-hospital formula supplementation and (2) risk factors for in-hospital formula supplementation. We surveyed 150 low-income mothers in a Washington, DC, clinic. Sixty percent had initiated breastfeeding, and 78% of these breastfed infants received formula supplementation in the hospital. There was no clear medical need for supplementation for 87% of the breastfed infants receiving supplementation. Infants of mothers who did not attend a prenatal breastfeeding class were almost 5 times more likely to receive in-hospital formula supplementation than those infants whose mothers had attended a class (OR, 4.7; 95% CI, 1.05-21.14). Improved knowledge about breastfeeding among nursing and medical providers is important to minimize unnecessary formula supplementation for breastfed infants.

An assessment of the impact of breastfeeding clinic attendance on women's breastfeeding experiences

Breastfeeding clinics aim to increase breastfeeding duration and diminish breastfeeding difficulties. Actual improvement in the duration and satisfaction of the breastfeeding experience for women using these clinics remains unknown. This observational study assessed the impact of a Québec City breastfeeding clinic's interventions on breastfeeding duration and satisfaction among women experiencing breastfeeding difficulties in comparison with women who did not receive clinic services. The study surveyed 86 women using telephone questionnaires and semistructured interviews. After adjusted logistic regression analysis, women who attended the clinic had a higher probability of breastfeeding for at least 6 months (odds ratio [OR] = 4.34; 95% confidence interval [CI] = 1.35-13.96) than women from the comparison group. They also had a higher probability of being satisfied with their breastfeeding experience (OR = 4.17; 95% CI = 1.31-13.22). Physical and moral support could explain this influence. Larger studies on breastfeeding clinics are needed to confirm their role in enhancing breastfeeding duration and satisfaction.

Antenatal peer support workers and initiation of breast feeding: cluster randomised controlled trial

OBJECTIVE

To assess the effectiveness of an antenatal service using community based breastfeeding peer support workers on initiation of breast feeding.

DESIGN

Cluster randomised controlled trial.

SETTING

Community antenatal clinics in one primary care trust in a multiethnic, deprived population.

PARTICIPANTS

66 antenatal clinics with 2511 pregnant women: 33 clinics including 1140 women were randomised to receive the peer support worker service and 33 clinics including 1371 women were randomised to receive standard care.

INTERVENTION

An antenatal peer support worker service planned to comprise a minimum of two contacts with women to provide advice, information, and support from approximately 24 weeks' gestation within the antenatal clinic or at home. The trained peer support workers were of similar ethnic and sociodemographic backgrounds to their clinic population.

MAIN OUTCOME MEASURE

Initiation of breast feeding obtained from computerised maternity records of the hospitals where women from the primary care trust delivered.

RESULTS

The sample was multiethnic, with only 9.4% of women being white British, and 70% were in the lowest 10th for deprivation. Most of the contacts with peer support workers took place in the antenatal clinics. Data on initiation of breast feeding were obtained for 2398 of 2511 (95.5%) women (1083/1140 intervention and 1315/1371 controls). The groups did not differ for initiation of breast feeding: 69.0% (747/1083) in the intervention group and 68.1% (896/1315) in the control groups; cluster adjusted odds ratio 1.11 (95% confidence interval 0.87 to 1.43). Ethnicity, parity, and mode of delivery independently predicted initiation of breast feeding, but randomisation to the peer support worker service did not.

CONCLUSION

A universal service for initiation of breast feeding using peer support workers provided within antenatal clinics serving a multiethnic, deprived population was ineffective in increasing initiation rates.

A quasi-experimental evaluation of a breastfeeding support program for low income women in Michigan

We examined the effectiveness of a peer counseling breastfeeding support program for low income women in Michigan who participate in WIC. Because there was more demand for services than could be met by the program, many women who requested services were not subsequently contacted by a peer counselor. We used a quasi-experimental methodology that utilized this excess demand for services to estimate the causal effect of the support program on several breastfeeding outcomes. We relied on data derived from administrative and survey-based sources. After providing affirmative evidence that our key assumption is consistent with the data, we estimated that the program caused the breastfeeding initiation to increase by about 27 percentage points and the mean duration of breastfeeding to increase by more than 3 weeks. The support program we evaluated was very effective at increasing breastfeeding among low income women who participate in WIC, a population that nationally breastfeeds at rates well below the national average and below what is recommended by public health professionals. Given the substantial evidence that breastfeeding is beneficial for both the child and mother, the peer counseling breastfeeding support program should be subjected to a cost/benefit analysis and evaluated at other locales.

[Effect of postpartum breast-feeding support by nurse on the breast-feeding prevalence]

PURPOSE

The purpose of this study was to investigate the effects of the professional nurse's postpartum breast-feeding support on breast-feeding prevalence for mothers who delivered in Baby-Friendly Hospitals (BFH).

METHODS

This quasi experimental study was designed with a nonequivalent control group post test. The subjects of this study were 55 mothers who were hospitalized in the delivery room of a university hospital which was selected as a BFH in Daegu from October 1, 2005 to June 30, 2006. Twenty nine mothers were assigned to the experimental group and 26 mothers to the control group. Postpartum breast-feeding support by nurses' telephone calls to the experimental group was provided once a week for 4 weeks postpartum and then once a month for 16 weeks postpartum. Four post tests were given at postpartum week 4, 8, 12, and 16. The control group was given a telephone call at postpartum week 4, 8, 12, and 16.

RESULTS

The breastfeeding prevalence of the experimental group was significantly higher than that of the control group for each period.

CONCLUSION

Postpartum breast-feeding support by nurses may be a useful intervention to increase breast-feeding prevalence.

Effect of low cost public health staff training on exclusive breastfeeding

OBJECTIVE

To assess the effectiveness and feasibility of on the job staff training and supportive supervision to improve six months Exclusive Breastfeeding (EBF).

METHODS

A longitudinal study was conducted in a public health field practice area-Sri Lanka in 2006-2007. Three breastfeeding counseling sessions were conducted for public health midwives. Supportive supervision and on the job training were done by two public health physicians. Pre and post intervention independent cross sectional studies were conducted to assess the effectiveness of the programme. The study sample consisted of mother-infant pairs where infants were aging 6 to 12 months, attending child welfare clinics. Primary outcome measure was the proportion of infants who received EBF up to 6 months. Logistic regressing model was used for analysis of predictors of EBF.

RESULTS

Study sample consisted of 336 mother-infant pairs (pre 139, post 197). Proportion of mothers who breastfed their infants exclusively for six months improved from 19% to 70% after the intervention. The median duration of EBF increased from 4 months to 6 months (inter-quartile range 2-6 and 5-6 months respectively). Unconfounded effect of intervention on 6 months EBF in logistic regression model was highly significant (OR=13.67. p<0.001). Intervention significantly reduced the bottle feeding rate (OR=0.212, p<0.001) but not formula feeding (OR=1.146. p=0.642). Of potential predictors assessed. Sinhalese mothers than Muslim mothers (OR=3.37, p<0.001) and employed mothers compared to housewives (OR=4.45. p=0.014) were more likely to breastfeed their infants upto six months. Parity, maternal education and maternal age were not significantly associated with six months EBF.

CONCLUSIONS

The existing public health infrastructure can be used effectively to improve six months EBF in places where the care is given primarily by public health system.

Predictors of the duration of exclusive breastfeeding among first-time mothers

Few women currently meet revised WHO recommendations to breastfeed exclusively for 6 months postpartum. In this prospective study we aimed to determine the influence of socio-demographic, psychosocial, and perinatal factors on the length of exclusive breastfeeding among 189 Canadian primiparous mothers. A majority of the participants did not meet their exclusive breastfeeding goals, and only 5% breastfed exclusively for a full 6 months. Breastfeeding self-efficacy, in-hospital formula supplementation, prenatal class attendance, and type of delivery independently predicted exclusive breastfeeding duration. Findings underscore the complex interplay of factors influencing breastfeeding, highlight the early postpartum weeks as a critical period for the establishment of exclusive breastfeeding, and suggest the need for a continuum of pre- and postnatal strategies for prolonging the exclusive breastfeeding period.

A systematic review of professional support interventions for breastfeeding

OBJECTIVES

The objectives of this systematic review were first, to describe how breastfeeding is professionally supported during pregnancy, at maternity hospitals and during the postnatal period. Secondly, to find out how effective interventions are in supporting breastfeeding.

BACKGROUND

Breastfeeding is an effective way to promote the health of infants. In many countries, the rates for breastfeeding remain lower than recommended. Many studies have examined breastfeeding promotion interventions; some of them are successful and some fail. It is important to find effective combinations of support.

DESIGN

Systematic review.

METHODS

Search of CINAHL, Medline and Cochrane Central Register databases were conducted for data collection. The search was limited to articles published in Finnish, Swedish and English between the year 2000 and March 2006, focusing on breastfeeding and breastfeeding support interventions. Two reviewers independently analysed 36 articles in the final analysis.

RESULTS

Interventions expanding from pregnancy to the intrapartum period and throughout the postnatal period were more effective than interventions concentrating on a shorter period. In addition, intervention packages using various methods of education and support from well-trained professionals are more effective than interventions concentrating on a single method.

CONCLUSIONS

During pregnancy, the effective interventions were interactive, involving mothers in conversation. The Baby Friendly Hospital Initiative (BFHI) as well as practical hands off -teaching, when combined with support and encouragement, were effective approaches. Postnatally effective were home visits, telephone support and breastfeeding centres combined with peer support. Relevance to clinical practice. Professionals need breastfeeding education and support of their organisations to act as breastfeeding supporters. The BFHI -programme is effective and it would be wise to include the core components of the programme in breastfeeding promotion interventions. Mothers benefit from breastfeeding encouragement and guidance that supports their self-efficacy and feelings of being capable and empowered, and is tailored to their individual needs.

Use of folic acid supplements, particularly by low-income and young women: a series of systematic reviews to inform public health policy in the UK

OBJECTIVE

To provide a basis for making recommendations on the potential to improve use of folic acid supplements in the UK, particularly among low-income and young women.

DESIGN

Systematic reviews of relevant research from 1989 to May 2006 in Europe, the USA, Canada, Australia and New Zealand.

RESULTS

Twenty-six systematic reviews and/or meta-analyses were identified from the wider public health literature, and eighteen studies on the effectiveness of preconception interventions were included. Ninety studies were identified which were directly relevant to folic acid supplement intake. There were factors that are particularly associated with lower rates of use of folic acid supplements. One of the most important of these is the link with unintended pregnancy, followed by age, socio-economic and ethnic group. Integrated campaigns can increase the use of folic acid supplements to some extent. Research trials indicated that: (i) printed resources and the mass media used in isolation are not effective in the longer term; and (ii) health-care-based initiatives can be effective and are more likely to be successful if they include making supplements easily available.

CONCLUSIONS

Campaigns and interventions have the potential to exacerbate socio-economic inequalities in folic acid use. One way of addressing this is to include elements that specifically target vulnerable women. To achieve and maintain an effect, they need to be based on good health promotion practice and to be sustained over a long period. However, even high-quality campaigns that increase use result in under half of women in the target group taking supplements.

Benefícios da amamentação para a saúde da mulher e da criança: um ensaio sobre as evidências

Este ensaio reúne uma seleção de estudos, particularmente revisões sistemáticas que têm contribuído para aumentar a compreensão sobre os benefícios do aleitamento materno para a criança e para a mulher e sua implementação. Realizou-se uma busca de artigos publicados a partir do ano 2000, sem, no entanto, deixar de lado estudos relevantes para o avanço do conhecimento publicados décadas atrás. Para a seleção dos estudos efetuou-se uma busca na Internet com base nas ferramentas disponíveis no PubMed e SciELO. Além dos aspectos para os quais há consenso, procurou-se incluir estudos sobre resultados controversos e outros que são instigantes, como os provenientes da neurobiologia. Verificam-se mudanças substanciais nas recomendações para políticas públicas em decorrência desses novos conhecimentos. Algumas investigações também têm sido realizadas com o objetivo de avaliar quais intervenções seriam mais efetivas para um aumento das práticas de amamentação. Procurou-se neste artigo dar destaque a: recomendações atuais sobre alimentação da criança pequena; importância da amamentação no início da vida; implicações do aleitamento materno para a saúde da criança; implicações do aleitamento materno para a saúde da mulher; e efetividade de algumas ações pró-amamentação.

Prevalence of breastfeeding among a multiethnic population in Hawaii

INTRODUCTION

The purpose of this study, conducted in a multiethnic population in Hawaii, was to estimate the prevalence of breastfeeding at six months of age, exclusive and otherwise, as well as to identify positively and negatively associated factors.

METHODS

A content-valid survey was conducted among a random stratified sample, and a printed questionnaire was sent to mothers of infants aged 7-10 months. A response rate of 70% yielded 701 completed surveys.

RESULTS

At six months after birth, some breastfeeding was practiced by 54% of respondents. The rate of exclusive breastfeeding was approximately 16% at six months. Race and ethnicity assessment showed that Whites had the highest rates and Filipinos the lowest. Formula use in the hospital was most significantly associated with lower breastfeeding rates at six months.

CONCLUSIONS

Exclusive breastfeeding for six months, even in a state with extremely high initiation rates, is seldom achieved. Formula use in the maternity units should be reduced, and intensive targeted study and education of the Filipino community should be undertaken.

Factors affecting exclusive breastfeeding of healthy babies aged zero to four months: a community-based study of Turkish women

AIM

The purpose of this study was to determine the factors that affect exclusive breastfeeding of healthy babies aged 0-4 months.

BACKGROUND

Both the World Health Organization (WHO) and UNICEF recommend feeding babies of 0-6 months exclusively with breast milk and starting complementary foods after the sixth month. In Turkey, however, a vast majority of babies 1-5 months of age (89.4%) are given complementary foods.

METHODS

This cross-sectional study was conducted in central Ankara province, with a sampling of 514 individuals who were selected using the convenience sampling method.

RESULTS

Of the 514 mothers who participated in my research, 260 (50.6%) were found to be feeding their babies exclusively with breast milk; 77 (15.0%), with breast milk + water; 87 (16.9%), with breast milk + baby formula; 70 (13.6%), with breast milk + baby formula + other foods; and 20 (3.9%), baby formula + other foods. Based on multivariate logistic regression analysis results, the mother's employment [odds ratio (OR) = 0.488; 95% confidence interval (CI) = 0.288-0.827) considerably reduced the incidence of complementary foods, while frequent crying of the baby (OR = 1.687; 95% CI = 1.125-2.530) significantly increased the use of supplementary foods in infant nutrition.

CONCLUSION

This study concluded that frequent crying of the baby increases the likelihood of giving the baby complementary foods. Midwives and nurses can encourage exclusive breastfeeding behaviour by providing individual education and counselling to women whose babies cry frequently.

RELEVANCE TO CLINICAL PRACTICE

Exclusive breastfeeding of babies aged 0-6 months is crucial for the development and growth of the baby and instrumental in reducing infant morbidities and mortalities. One factor that increases the likelihood of provision of complementary foods is frequent crying of the baby. Midwives and nurses can encourage exclusive breastfeeding behaviour by providing individual education and counselling to women whose babies cry frequently.

Breastfeeding attitudes and reported problems in a national sample of WIC participants

Recent reports indicate that breastfeeding rates continue to be dramatically lower among WIC participants, compared with other US mothers. The WIC Infant Feeding Practices Study was a nationally representative 1-year longitudinal study of WIC participants that obtained information about attitudes regarding infant feeding and about infant-feeding practices. Hispanic mothers were most likely to agree with statements about benefits of breastfeeding, and Black mothers were most likely to agree with statements about barriers. Concern about insufficient milk was common in all ethnic groups. Perceived benefits were associated with breastfeeding initiation (P < .05), longer breastfeeding duration (P < .01), and later formula initiation (P < .01); for barriers, the opposite pattern was found. Breastfeeding mothers who reported concern about insufficient milk breastfed for shorter durations (P < .001) and initiated formula earlier (P < .01). These results suggest possible messages that should be communicated as part of a re-energized WIC breastfeeding promotion campaign. In particular, maternal anxiety about insufficient breast milk must be addressed.

Rethinking research in breast-feeding: a critique of the evidence base identified in a systematic review of interventions to promote and support breast-feeding

Objective

To appraise critically the relevance and value of the evidence base to promote and support the duration of breast-feeding, with a specific focus on disadvantaged groups.

Design

A systematic review was conducted of intervention studies relevant to enhancing the duration of breast-feeding; topics included public health, public policy, clinical issues, and education, training and practice change. A systematic search was conducted. Eighty studies met the inclusion criteria. Data were systematically extracted and analysed. Full results and recommendations are reported elsewhere. Here a critique of the evidence base – topics, quality and gaps – is reported.

Results

Many studies were substantially methodologically flawed, with problems including small sample sizes, inconsistent definitions of breast-feeding and lack of appropriate outcomes. Few were based on relevant theory. Only a small number of included studies (10%) were conducted in the UK. Very few targeted disadvantaged subgroups of women. No studies of policy initiatives or of community interventions were identified. There were virtually no robust studies of interventions to prevent and treat common clinical problems, or of strategies related to women's health issues. Studies of health professional education and practice change were limited. Cost-effectiveness studies were rare.

Conclusions

Policy goals both in the UK and internationally support exclusive breast-feeding until 6 months of age. The evidence base to enable women to continue to breast-feed needs to be strengthened to include robust evaluations of policies and practices related to breast-feeding; a step change is needed in the quality and quantity of research funded.

The 'Earlybird' gets the breastmilk: findings from an evaluation of combined professional and peer support groups to improve breastfeeding duration in the first eight weeks after birth

Australia has high initiation rates of breastfeeding, but the challenges of establishing and maintaining breastfeeding in the first few months of infant life result in many women changing to artificial formula feeding. This paper reports on the impact of a new strategy to improve breastfeeding duration rates in the first 8 weeks post-partum. The Earlybird Program (EBP) combines the professional expertise of child and family health (C&FH) nurses with the expertise of the participating mothers to support each other in establishing breastfeeding in the first 8 weeks. This retrospective study compared the breastfeeding patterns of first-time mothers who attended the EBP, with the breastfeeding patterns of mothers who accessed individual appointments with the nurses in a 12-month period, and examined the predictors of continued breastfeeding at 8 weeks. The total sample comprised 193 infant records. Women who selected the EBP were more likely to be employed and less likely to be categorized as non-English speaking background. These women also had more visits to the C&FH service. Logistic regression was used to determine the factors associated with breastfeeding cessation at 8 weeks post-natal. After adjusting for variables, only exclusive breastfeeding at first visit and attending the EBP were significant predictors of continuing to breastfeed at 8 weeks. Facilitation skills that recognize the expertise of participating women were considered an important aspect of the programme.

Attitudes and knowledge on breastfeeding among paediatricians, family physicians, and gynaecologists in Israel

OBJECTIVES

Many women in Western countries fail to breastfeed long enough. The aim of this study was to examine the attitudes and knowledge of Israeli family physicians (FPs), gynaecologists and paediatricians towards breastfeeding.

DESIGN AND PARTICIPANTS

A questionnaire examined Physicians' attitudes towards breastfeeding and their role in encouraging it, their sources of information and adequacy of knowledge.

RESULTS

Four hundred and seventy-eight physicians responded to the survey: 123 FPs, 134 gynaecologists and 221 paediatricians. Ninety to -hundred per cent of physicians agreed that breastfeeding is the best feeding method for infants and agree that physicians should encourage it. Less than 20% of physicians discuss breastfeeding with pregnant women, and less than 30% discuss it with women 3 months or more postnatally. On average, physicians correctly answered 3.5 +/- 1.7 out of seven questions examining knowledge. Physicians state their main sources of information as their own experience and reading. One hundred and ninety physicians specified how they encourage breastfeeding--of those, 75.3% speak only of the advantages of breastfeeding.

CONCLUSION

Physicians have a positive disposition towards breastfeeding but their knowledge is somewhat low. It seems awareness is lacking to the importance of continuous support and practical guidance beginning before birth and continuing until 3 months or more postnatal.

Support for breastfeeding mothers

BACKGROUND

There is extensive evidence of the benefits of breastfeeding for infants and mothers. In 2003, the World Health Organization (WHO) recommended infants be fed exclusively on breast milk until six months of age. However, breastfeeding rates in many developed countries continue to be resistant to change.

OBJECTIVES

To assess the effectiveness of support for breastfeeding mothers.

SEARCH STRATEGY

We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (January 2006), MEDLINE (1966 to November 2005), EMBASE (1974 to November 2005) and MIDIRS (1991 to September 2005).

SELECTION CRITERIA

Randomised or quasi-randomised controlled trials comparing extra support for breastfeeding mothers with usual maternity care.

DATA COLLECTION AND ANALYSIS

Two authors independently assessed trial quality and extracted data.

MAIN RESULTS

We have included 34 trials (29,385 mother-infant pairs) from 14 countries. All forms of extra support analysed together showed an increase in duration of 'any breastfeeding' (includes partial and exclusive breastfeeding) (relative risk (RR) for stopping any breastfeeding before six months 0.91, 95% confidence interval (CI) 0.86 to 0.96). All forms of extra support together had a larger effect on duration of exclusive breastfeeding than on any breastfeeding (RR 0.81, 95% CI 0.74 to 0.89). Lay and professional support together extended duration of any breastfeeding significantly (RR before 4-6 weeks 0.65, 95% 0.51 to 0.82; RR before 2 months 0.74, 95% CI 0.66 to 0.83). Exclusive breastfeeding was significantly prolonged with use of WHO/UNICEF training (RR 0.69, 95% CI 0.52 to 0.91). Maternal satisfaction was poorly reported.

AUTHORS' CONCLUSIONS

Additional professional support was effective in prolonging any breastfeeding, but its effects on exclusive breastfeeding were less clear. WHO/UNICEF training courses appeared to be effective for professional training. Additional lay support was effective in prolonging exclusive breastfeeding, while its effects on duration of any breastfeeding were uncertain. Effective support offered by professionals and lay people together was specific to breastfeeding and was offered to women who had decided to breastfeed. Further trials are required to assess the effectiveness (including cost-effectiveness) of both lay and professional support in different settings, particularly those with low rates of breastfeeding initiation, and for women who wish to breastfeed for longer than three months. Trials should consider timing and delivery of support interventions and relative effectiveness of intervention components, and should report women's views. Research into appropriate training for supporters (whether lay or professional) of breastfeeding mothers is also needed.

Special considerations for breastfeeding the infant with spina bifida

At present, no research has examined the unique breastfeeding needs of a mother and her infant with spina bifida (SB). This mother-infant dyad will face many unique challenges during the prenatal period, postdelivery, and postsurgical repair of the myelomeningocele (MMC). Each of these periods presents an opportunity for effective evidence-based nursing interventions to promote successful provision of human milk (HM). Beyond the need for nursing care during these crucial events, parents need education about the potential benefits of HM for the long-term complications of SB. Although there is no published evidence specifically related to the benefits of HM for mothers and their infants with SB, studies related to the general benefits of HM suggest that the mothers may enjoy enhanced maternal psychological adjustment while infants with SB may experience improved pain management, reduced infection rates, decreased incidence of allergy, improved cognitive development, and decreased incidence of obesity. Further research is needed to better understand the unique relationship between HM and SB.

Simple Antenatal Preparation to Improve Breastfeeding Practice

OBJECTIVE

To address the impact of simple antenatal educational interventions on breastfeeding practice.

METHODS

A randomized controlled trial was carried out in a tertiary referral center from May 2002 to December 2004. A random sample of eligible low-risk antenatal patients was recruited from clinics in the National University Hospital, Singapore. Group A received breastfeeding educational material and individual coaching from a lactation counselor. Group B received breastfeeding educational material with no counseling. Group C received routine antenatal care only.

RESULTS

A total of 401 women were recruited. Mothers receiving individual counseling and educational material practiced exclusive and predominant breastfeeding more often than mothers receiving routine care alone at 3 months (odds ratio [OR] 2.6, 95% confidence interval [CI] 1.2-5.4) and 6 months (OR 2.4, 95% CI 1.0-5.7) postpartum. More mothers practiced exclusive and predominant breastfeeding at 6 months among women receiving individual counseling compared with women exposed to educational material alone (OR 2.5, 95% CI 1.0-6.3).

CONCLUSION

Where breastfeeding practices are suboptimal, simple one-encounter antenatal education and counseling significantly improve breastfeeding practice up to 3 months after delivery. Provision of printed or audiovisual educational material is not enough. Health care workers should make every effort to have one face-to-face encounter to discuss breastfeeding with expectant mothers before they deliver.

LEVEL OF EVIDENCE

I.

Benefits and risks of breastfeeding

In the absence of significant, unpreventable risks, breastfeeding should be the norm for the nourishment of human infants and should, therefore, be encouraged for populations in all countries. Continued efforts of international and national agencies and healthcare professionals to aid and abet breastfeeding, reduce the risks that occur in some women during breastfeeding, provide the safest substitutes for human milk when that is necessary, and encourage further research into the posed questions should considerably improve the health of many children.

Longitudinal patterns of breastfeeding initiation

Objectives: Information regarding the type and scope of preconception care programs in the United States is scant. We evaluated State Title V measurement and indicator data and abstracts presented at the National Summit on Preconception Care (June 2005) in order to identify existing programs and innovative strategies for preconception health promotion.

Methods: We used the web-based Title V Information System to identify state Performance Measures and Priority Needs pertaining to preconception health as reported for the 2005–2010 Needs Assessment Cycle. We also present a detailed summary of the abstracts presented at the National Summit on Preconception Care.

Results: A total of 23 states reported a Priority Need that focused on preconception health and health care. Forty-two states and jurisdictions identified a Performance Measure associated with preconception health or a related indicator (e.g., folic acid, birth spacing, family planning, unintended pregnancy, and healthy weight). Nearly 60 abstracts pertaining to preconception care were presented at the National Summit and included topics such as research, programs, patient or provider toolkits, clinical practice strategies, and public policy.

Conclusions: Strategies for improving preconception health have been incorporated into numerous programs throughout the United States. Widespread recognition of the benefits of preconception health promotion is evidenced by the number of states identifying related indicators.

The impact of a new universal postpartum program on breastfeeding outcomes

The Ontario Mother and Infant Study II examined changes in postpartum health outcomes, including breastfeeding initiation and discontinuation, for mothers and their infants and compared these results to data collected prior to the initiation of the Universal Hospital Stay and Postpartum Home Visiting Program policy change in 1998. Data were collected using cross-sectional surveys before discharge and at 4 weeks postdischarge. Ninety percent of the women surveyed at 4 weeks postpartum initiated breastfeeding. Of these, 84% were still breastfeeding at 4 weeks postpartum. None of the 3 major program components-extended length of stay, a postpartum phone call from a public health worker, or a postpartum in-home visit-were associated with breastfeeding continuation to 4 weeks. Discontinuation before 4 weeks postdischarge was associated with maternal attitudes toward breastfeeding, formula feeding or supplementation in hospital, infant readmission, and use of walk-in clinics for infant care.

Breast-feeding in Athens, Greece: factors associated with its initiation and duration

OBJECTIVES

To determine the prevalence, examine the influence of hospital practices and investigate potential determinants of breast-feeding in Athens.

PATIENTS AND METHODS

Three hundred twelve mothers provided information regarding feeding practices at certain maternity hospitals in Athens, at 40 days and 6 months postpartum. Multiple logistic regression analysis was performed to evaluate the association between the initiation and maintenance of breast-feeding and potential risk factors.

RESULTS

Although almost 90% of newborn infants were given a breast milk substitute one or more times during the first 2 days at the maternity hospital, the exclusive breast-feeding percentage on the last day of hospital stay reached 85%. Breast-feeding and exclusive breast-feeding percentages dropped to 55% and 35%, respectively, at 40 days postpartum and to 16% and 12%, respectively, at 6 months postpartum. While in the hospital, 3% of mothers initiated breast-feeding within 1 hour of labor, only 34% were informed about the advantages of breast-feeding by health professionals and 42% were trained to breast-feed by the midwives. "Rooming-in" was not practiced in the private hospitals. The educational level was positively associated with the initiation of breast-feeding [odds ratio (OR): 1.36, confidence interval (CI): 1.02-1.81], the mother's body mass index was negatively associated with the maintenance of breast-feeding for 40 days (OR: 0.56, CI: 0.32-0.98) and 6 months (OR: 0.28, CI: 0.06-1.26) and a caesarean section was negatively associated with the initiation (OR: 0.24, CI: 0.11-0.49) and maintenance of breast-feeding (OR: 0.42, CI: 0.20-0.89).

CONCLUSIONS

Breast-feeding is not appropriately supported in certain maternity hospitals in Athens, and this is probably the cause of observed low breast-feeding prevalence.

Food behaviors and other strategies to prevent and treat pediatric overweight

OBJECTIVE

To summarize the evidence for the following six strategies to prevent or treat overweight among children: promoting breastfeeding, promoting physical activity, reducing TV/video viewing, increasing fruit and vegetable consumption, reducing sugar-sweetened drink consumption, and reducing portion sizes.

METHODS

Summarization of the relevant literature including review articles, relevant newly published work, the Institute of Medicine's Report on Preventing Childhood Obesity and the Surgeon General's Call to Action to Prevent and Decrease Overweight and Obesity, 2001. This is not a comprehensive review.

RESULTS

Evidence for the association between each strategy and overweight varies. For breastfeeding, physical activity, and TV viewing, there are large review studies. Breastfed children may have a small reduction in risk for overweight. Participation in physical activity may reduce the risk of overweight among school-aged children and adolescents. For preschool- and school-aged children, reducing TV viewing time may reduce their risk of overweight, but most studies report small significant associations. Evidence for an association between each dietary factor and overweight is limited and inconclusive. The biggest gaps in evidence are for the effectiveness of interventions using these strategies. The reviewed interventions based on increasing physical activity (n=7) were effective. Two randomized trials suggest that reducing TV viewing reduces overweight. No intervention studies were found that examined the effectiveness of changing fruit and vegetable consumption, sugar-sweetened drink consumption, or portion sizes. Further clarification of the effect of breastfeeding on obesity is needed.

CONCLUSIONS

These six strategies are reasonable ways to attempt prevention or treatment of overweight in children. Strength of the evidence varies by strategy. The key finding is that more applied research is needed to determine the effectiveness of these and other strategies.

The effect of a programme of organised and supervised peer support on the initiation and duration of breastfeeding: a randomised trial

BACKGROUND

Peer support may improve breastfeeding rates but the evidence is inconclusive. Previous studies and reviews recommend trials in different healthcare settings.

AIM

To test if a specified programme of peer support affects the initiation and/or the duration of breastfeeding.

DESIGN OF STUDY

A two-group randomised controlled trial of peer support for breastfeeding with evaluation of breastfeeding initiation and duration on an intention-to-treat basis.

SETTING

General practice in Ayrshire, Scotland.

METHOD

Following informed consent, 225 women at 28 weeks gestation were allocated to control or peer support group by post-recruitment concealed allocation. All peer support and control group mothers received normal professional breastfeeding support. Additionally, those in the peer support group still breastfeeding on return home from hospital had peer support until 16 weeks.

RESULTS

Thirty-five of the 112 (31%) women in the peer support group were breastfeeding at 6 weeks compared to 33/113 (29%) in the control group, a difference of 2% (95% confidence interval = -10% to 14%). The median breastfeeding duration for all women in the peer support group was 2 days compared to 1 day for the control group and the Kaplan-Meier survival plot shows the peer support group overall breastfeeding slightly longer than the control group, with no statistically significant difference by logrank test (P = 0.5). The median breastfeeding duration among primagravidae in the peer support group was 7 days, compared to 3 days for the control group. Among women who started to breastfeed the medians were 72 days in the peer support group and 56 days in the control group. These differences were not statistically significant.

CONCLUSIONS

Peer support did not increase breastfeeding in this population by a statistically significant amount.

Breastfeeding Behaviors and Experiences of Adolescent Mothers

PURPOSE

: To examine the breastfeeding experiences and related behaviors of adolescent mothers after discharge from the hospital.

STUDY DESIGN AND METHODS

: Descriptive telephone survey with both open-and closed-ended questions. Outcome variables included breastfeeding experiences and infant feeding practices. A convenience sample of mothers (N = 53), ranging in age from 14 to 19 years, were interviewed by telephone 5 months to 2 years postdelivery.

RESULTS

: Over one half (60.3%) of the adolescent mothers breastfed for 2 months or longer (average 3.15 months), only 22.6% breastfed for 6 months or more, and 39.6% breastfed for 1 month or less. Friends, families, and healthcare professionals were supportive of breastfeeding, but participants found prenatal and postpartum education about breastfeeding to be limited. Many indicated that they were not plainly informed about the superiority of breast milk and the health advantages of breastfeeding. One mother stated, "They just asked if I wanted to bottle or breastfeed and didn't tell me about the benefits of breastfeeding."

CLINICAL IMPLICATIONS

: Nurses and physicians who provide care for childbearing women need to promote breastfeeding among adolescents in a better way. Prenatal anticipatory guidance related to the physical aspects of breastfeeding, support after adolescent mothers are discharged from the hospital, and advocacy for breastfeeding in the school and workplace setting are warranted. Nurses should consider establishing postpartum education programs for breastfeeding adolescents, for almost all of the participants in this study expressed the need for more postnatal breastfeeding support as indicated by this representative statement:"I think that it would help you to be able to breastfeed if nurses could phone call you more than just once; my baby latched on good in the hospital; I had trouble later after we went home."

Effectiveness of a breastfeeding peer coaching intervention in rural Scotland

BACKGROUND

Breastfeeding initiation in Scotland in 2000 was 63 percent, compared with over 90 percent in Norway and Sweden. Although peer support is effective in improving exclusivity of breastfeeding in countries where over 80 percent of women initiate breastfeeding, the evidence for effectiveness in countries with lower initiation is uncertain. Our primary aim was to assess whether group-based and one-to-one peer breastfeeding coaching improves breastfeeding initiation and duration.

METHODS

Action research methodology was used to conduct an intervention study in 4 geographical postcode areas in rural northeast Scotland. Infant feeding outcomes at birth and hospital discharge; at 1, 2, and 6 weeks; and at 4 and 8 months were collected for 598 of 626 women with live births during a 9-month baseline period and for 557 of 592 women with live births during a 9-month intervention period. Groups met in 5 locations, with 266 groups meeting in the period when intervention women were eligible to attend. Data on place of birth and length of postnatal hospital stay were also collected. Control data from 10 other Health Board areas in Scotland were compared. An intention-to participate survey about coaching participation was completed by 206 of 345 women initiating breastfeeding. Group attendance data were collected by means of 266 group diaries.

RESULTS

There was a significant increase in any breastfeeding of 6.8 percent from 34.3 to 41.1 percent (95% CI 1.2, 12.4) in the study population at 2 weeks after birth compared with a decline in any breastfeeding in the rest of Scotland of 0.4 percent from 44 to 43.6 percent (95% CI -1.2, 0.4). Breastfeeding rates increased compared with baseline rates at all time points until 8 months. However, the effect was not uniform across the 4 postcode areas and was not related to level of deprivation. Little difference was seen in receipt of information and knowledge about the availability of coaching among areas. All breastfeeding groups were well attended, popular, and considered helpful by participants. A minority of women (n = 14/206) participated in formal one-to-one coaching. Women who received antenatal, birth, and postnatal care from community midwife-led units were more likely to be breastfeeding at 2 weeks (p = 0.007) than women who received some or all care in district maternity units.

CONCLUSIONS

Group-based and one-to-one peer coaching for pregnant women and breastfeeding mothers increased breastfeeding initiation and duration in an area with below average breastfeeding rates.

Protection, promotion and support of breastfeeding in low-income countries

The rates of exclusive breastfeeding and the duration of breastfeeding fall short of what is recommended by the Global Strategy on Infant and Young Child Feeding worldwide. In low-income countries this is associated with a great excess of avoidable childhood death and disease. A higher degree of protection, promotion and support of breastfeeding has the potential to avert the death of about 1.3 million children per year and to prevent much of the associated individual and social sufferings. This paper presents some evidence about interventions that are effective to protect, promote and support breastfeeding in the health system and in the community. These interventions should not be implemented in isolation, but as part of an integrated and intersectoral programme, with a participatory approach that takes local cultural characteristics into account. Lack of political will is probably the most important factor associated with inadequate protection, promotion and support of breastfeeding.

How to integrate a lactation consultant in an outpatient clinic environment

Successful efforts in improving breastfeeding initiation rates at an urban teaching hospital prompted the hospital to create a lactation consultant (LC) position in the outpatient setting to focus on breastfeeding duration. This article reviews the complexity of the clinic setting, with the challenges and benefits of the consultant's first year in one of the hospital's outpatient clinics. Preliminary data collected by the consultant suggest that patients counseled by the LC in the outpatient clinic setting have longer breastfeeding duration rates.

Mother's reactions to a skills-based breastfeeding promotion intervention

We interviewed women who participated in a breast-feeding promotion intervention study about whether and how participation affected their infant feeding choices, and if they would recommend such an intervention to others. The larger study, a randomized controlled trial (RCT) of an individualized, pre- and post-natal lactation consultant (LC) intervention, enrolled 382 low-income primarily Black and Hispanic women in New York City. Twenty-one women completed qualitative exit interviews for this study (11 from the Intervention group and 10 Controls). Several of the Controls stated that the post-partum study interviews were a source of support, and made them more conscious of how they fed their infant. The Intervention Group was asked about contacts with the study 'Mother-Baby specialist' (i.e. LC), including what was and wasn't helpful. The Intervention Group participants described the Mother-Baby Specialist as key in their decision to initiate and maintain breastfeeding. They credit her direct skills and positive reinforcement with their confidence and perseverance to breastfeed. The success of the intervention is attributed to technical assistance from a trained lactation consultant within the context of a relationship built on encouragement, guidance and support.

Randomized, controlled trial of a prenatal and postnatal lactation consultant intervention on duration and intensity of breastfeeding up to 12 months

OBJECTIVE

To determine whether an individualized, prenatal and postnatal, lactation consultant intervention resulted in increased cumulative intensity of breastfeeding up to 52 weeks.

DESIGN

The randomized, nonblinded, controlled trial recruited women from prenatal care. Baseline prenatal interviews covered demographic data and breastfeeding experience, intention, and knowledge. Interviews at 1, 2, 3, 4, 6, 8, 10, and 12 months after birth collected data on weekly feeding patterns, infant illness, and infant health care use.

SETTING

Two community health centers serving low-income, primarily Hispanic and/or black women.

PARTICIPANTS

The analytic sample included 304 women (intervention: n = 145; control: n = 159) with > or = 1 postnatal interview.

INTERVENTION

Study lactation consultants attempted 2 prenatal meetings, a postpartum hospital visit, and/or home visits and telephone calls. Control subjects received the standard of care.

OUTCOME MEASURES

Cumulative breastfeeding intensity at 13 and 52 weeks, based on self-reports of weekly feeding, on a 7-level scale.

RESULTS

The intervention group was more likely to breastfeed through week 20 (53.0% vs 39.3%). Exclusive breastfeeding rates were low and did not differ according to group. In multivariate analyses, control subjects had lower breastfeeding intensity at 13 weeks (odds ratio [OR]: 1.90; 95% confidence interval [CI]: 1.13-3.20) and 52 weeks (OR: 2.50; 95% CI: 1.48-4.21). US-born control subjects had lowest breastfeeding intensity at 13 weeks (OR: 5.22; 95% CI: 2.43-11.22) and 52 weeks (OR: 5.25; 95% CI: 2.44-11.29). There were no significant differences in breastfeeding intensity among the US-born intervention, foreign-born intervention, and foreign-born control groups.

CONCLUSIONS

This "best-practices" intervention was effective in increasing breastfeeding duration and intensity. Breastfeeding promotion should focus on US-born women and exclusive breastfeeding.

An evaluation of a telephone-based postnatal support intervention for infant feeding in a regional Australian city

BACKGROUND

Postnatal breastfeeding support in the form of home visits is difficult to accommodate in regional Australia, where hospitals often deal with harsh economic constraints in a context where they are required to provide services to geographically dispersed consumers. This study evaluated a predominantly telephone-based support service called the Infant Feeding Support Service.

METHODS

A prospective cohort design was used to compare data for 696 women giving birth in two regional hospitals (one public, one private) and participating in the support service between January and July 2003 with data from a cohort of 625 women who gave birth in those hospitals before the introduction of the support service. Each mother participating in the support service was assigned a lactation consultant. First contact occurred 48 hours after discharge, and approximately weekly thereafter for 4 weeks. Breastfeeding duration was measured at 3 months postpartum.

RESULTS

For women from the private hospital, the support service improved exclusive breastfeeding duration to 4.5 weeks postpartum, but these improvements were not evident at 3 months postpartum. No effects were observed for mothers from the public hospital. Quantitative and qualitative data demonstrated high levels of client satisfaction with the support service.

CONCLUSIONS

This small-scale, predominantly telephone-based intervention provided significant, although apparently context-sensitive, improvements to exclusive breastfeeding duration.

Longitudinal Patterns of Breastfeeding Initiation

Breastfeeding, in spite of proven benefits and energetic promotion, lags behind national goals, is less prevalent in disadvantaged populations, and declines across successive children in a family. Using longitudinally linked data from the New Jersey Electronic Birth Certificate (EBC) from 1996 to 2001, we found considerable fluidity in breastfeeding status at hospital discharge for births to the same mother. Among mothers who breastfed exclusively after the first birth, only 69% did so after the second (we refer to this as recurrence). Among mothers who exclusively formula fed after the first birth, 16% initiated exclusive breastfeeding after the second birth (referred to as recruitment). Combination feeding the first born, i.e., breastfeeding supplemented by formula, was followed by exclusive breastfeeding for 38% of second births. Rates of recurrence and recruitment differed in distinct ways by race/ethnicity and immigrant status. We conclude that breastfeeding initiation is not necessarily or exclusively a matter of fixed preferences, and that opportunities exist to expand breastfeeding to realize national goals by enhancing both recurrence and recruitment.

Clinical lactation practice: 20 years of evidence

Lactation consultants depend on a vast multidisciplinary knowledge base to support their practices. To coincide with the 20-year anniversary of the International Lactation Consultant Association, the authors sought to highlight the knowledge base to demonstrate how practice has been affected. Using standard databases, they extracted English-language scientific literature related to breastfeeding and maternal and infant health outcomes; factors associated with breastfeeding initiation, exclusivity, and duration; lactation physiology; common breastfeeding challenges; breastfeeding practices within vulnerable populations; health professional support of breastfeeding; and breastfeeding practices in developing countries of Africa. Summaries of research are provided to demonstrate scientific method and knowledge evolution. As the knowledge of the biological, behavioral, and environmental factors that affect breastfeeding continues to grow, researchers and lactation consultants will identify additional research areas. Thus, the cycle of describing and explaining phenomena, testing interventions to improve practice, and ultimately improving breastfeeding outcomes worldwide will continue.

Promoting nutrition in breastfeeding women

Nurses have a vital role in providing nutritional education to breastfeeding women. In this article, the authors discuss the nutritional requirements for breast-feeding women in terms of micronutrients, macronutrients, and minerals. They provide recommendations for women with vegetarian diets and low-income women enrolled in the Special Supplemental Nutrition Program for Women, Infants, and Children program who may have dietary deficiencies, and they present a directed case study to provide an example of how to perform a dietary assessment and the educational support that may be offered by nurses to breastfeeding women.

Avaliação do impacto de um programa de puericultura na promoção da amamentação exclusiva

Foi estudada a prevalência de amamentação exclusiva numa coorte histórica de crianças nascidas entre janeiro de 2000 e dezembro de 2002, de famílias de baixo nível sócio-econômico, residentes na área de abrangência de um Posto de Saúde de Atenção Primária, na periferia da cidade de Pelotas, Rio Grande do Sul, Brasil. Para a análise foi construída uma tábua de vida, cujo desfecho era a interrupção da amamentação exclusiva, mês a mês, após o nascimento. Entre as 112 crianças estudadas, a prevalência de amamentação exclusiva no primeiro mês de vida foi de 95,0%, caindo progressivamente para 81,0%, 64,0%, 53,0%, 39,0% e 35,0%, respectivamente, do segundo ao sexto mês. A mediana de duração da amamentação exclusiva foi de quatro meses; a mediana de duração da amamentação exclusiva e a prevalência de aleitamento exclusivo no sexto mês, superiores às taxas nacionais, indicam adequação do Programa de Puericultura na promoção da amamentação. No entanto, mais esforços devem ser despendidos para aumentar a prevalência da amamentação exclusiva até o sexto mês de vida.
