Health professional knowledge of breastfeeding: are the health risks of infant formula feeding accurately conveyed by the titles and abstracts of journal articles?

Does benefits-of-breastfeeding language or risks-of-formula-feeding language promote more-positive attitudes toward breastfeeding among midwives and nurses?

BACKGROUND

Midwives and nurses are crucial in breastfeeding support. Few studies have explored appropriate language for nursing education on breastfeeding. We assessed the impact of the language used on breastfeeding attitudes among midwives and nurses.

METHODS

A quasi-experimental study was conducted online in Japan among 174 midwives and nurses who had work experience in obstetrics or pediatrics. Participants were allocated to three groups to receive different text messages as the intervention (the benefit of breastfeeding for Group 1; the risk of formula feeding for Group 2; the importance of childcare for Group 3 as the comparison). The Japanese version of the Iowa Infant Feeding Attitude Scale (IIFAS-J) was used to assess breastfeeding attitudes before and after reading the texts. Also, participant reactions to the text were assessed by their responses to three statements. ANOVA, the chi-square test, and the t-test were used for outcome assessments.

RESULTS

The post-test IIFAS-J score was significantly higher than the pre-test score only for Group 1 (p <  0.01). The percentage of participants who agreed with the content of the text was 70.7% in Group 1 and 48.3% in Group 2. The percentage of participants who reported discomfort with the text was 34.5% in Group 1 and 55.2% in Group 2. No significant difference among groups existed regarding interest in the text. In all three groups, participants who agreed with the text had a higher post-test IIFAS-J score than those who disagreed with the text (6.85 points higher, p <  0.01 in Group 1; 7.19 points higher, p <  0.01 in Group 2; 8.00 points higher, p <  0.02 in Group 3). Discomfort with the text and interest in the text were associated with a significantly higher post-test IIFAS-J score in Group 1 and Group 2 but not in Group 3.

CONCLUSIONS

"Benefits of breastfeeding" language, which conveys the information in a positive manner, appears to be more appropriate than "risks of infant formula" language for creating a positive attitude toward breastfeeding in nursing education.

Why does the need for medication become a barrier to breastfeeding? A narrative review

PROBLEM

The need for medication during lactation can contribute to the early cessation of breastfeeding.

BACKGROUND

Breastfeeding women may require medication for acute or chronic health conditions. For some women this need for medication can become a barrier to breastfeeding; this is despite the fact that the majority of medications are considered to be compatible with lactation.

AIM

This narrative review aims to investigate factors relating to medicines safety that could contribute to medication unnecessarily becoming a barrier to breastfeeding.

METHODS

A selective literature search using PubMed, Scopus and Google Scholar was conducted over a 6-month period using the search terms "breastfeeding", "lactation", "medication" and "information". Articles were assessed to identify whether they addressed the impact of medication use on the decision to breastfeed.

FINDINGS

Fifty six articles were identified as having appropriate discussion about decision making for the safe use of medication during lactation. Themes identified included variable and conflicting safety advice for medicines; difficulty interpreting risks associated with medicine use; societal pressures faced by the breastfeeding woman; and the varied knowledge and training of health professionals involved in the care of breastfeeding women.

CONCLUSION

Poor quality of information about medicine safety during lactation can contribute to confusion in giving recommendations. This confusion can result in early cessation of breastfeeding or insufficient health care for the breastfeeding woman.

Maternal experiences of embodied emotional sensations during breast feeding: An Interpretative Phenomenological Analysis

OBJECTIVE

the purpose of this study was to explore mothers׳ experiences of embodied emotional sensations during breast feeding and to understand the meaning and consequences that such experiences may have on mothers' sense of self and the relationships they form with their children.

DESIGN

a qualitative design was applied to this study as it was judged as the most appropriate approach to this novel field of enquiry.

SETTING

the study was conducted in United Kingdom using a sample of mothers drawn from five different countries from Europe, America and Australia.

PARTICIPANTS

the sample consisted of 11 mothers who reported experiencing or having experienced negative embodied emotional sensations associated with breast feeding in the past five years.

MEASUREMENTS

semi-structured interviews were conducted with the mothers and interviews were transcribed to enable the process of data analysis. Interpretative Phenomenological Analysis (IPA; Smith et al., 2009a, 2009b) was chosen as a method of data analysis, enabling in depth understanding and interpretation of the meaning of mothers' experiences. IPA was chosen due to its idiographic commitment and particular interest in sense-making, phenomenology and hermeneutics.

FINDINGS

three themes were generated reflecting the multifaceted nature of breast feeding experiences (i) 'Breast feeding: An unexpected trigger of intense embodied emotional sensations incongruent with view of self', (ii) 'Fulfilling maternal expectations and maintaining closeness with the child', (iii) 'Making sense of embodied emotional sensations essential to acceptance and coping'.

CONCLUSIONS

breast feeding has the potential to trigger a range of conflicting cognitions and emotions in mothers that may impact on how mothers view themselves and relate to their children.

IMPLICATIONS FOR PRACTICE

increasing awareness about emotional breast feeding experiences and recognising the multifaceted, individual nature of difficulties around breast feeding enables professionals to offer mothers person-centred care and avoid making clinical decisions and recommendations based on inaccurate knowledge.

Mother's Beliefs, Attitudes, and Decision Making Related to Infant Feeding Choices

All mothers at some point make a decision about whether to breast- or formula feed their infant. Marital status, education, age, culture, and confidence have all been identified as variables affecting this decision. Previous research has concentrated on the decision-making process in breastfeeding mothers. This qualitative descriptive study investigated the beliefs, attitudes, and decisions of both breast- and formula-feeding mothers. Four categories were identified influencing maternal decision making: (a) infant nutritional benefits, (b) maternal benefits, (c) knowledge about infant feeding, and (d) personal and professional support. Analysis of the data indicated that mothers differed in their choice depending on whether they were infant- or maternal-centered and that most women combine both methods of feeding.

Developing and testing an online breastfeeding training among undergraduate nursing students

The benefits of breastfeeding for mothers and babies have been well documented in the scientific literature, with new evidence about the benefits continuing to emerge. The Surgeon General's call to action to support breastfeeding recommends mandatory breastfeeding education and training for all healthcare providers that deliver care to mothers and babies. The purpose of this study is to analyze the development of an online computer based breastfeeding training (BT) and the preliminary outcomes of this training. The development of this training included consultation with content and technology experts. The collection of preliminary outcomes related to breastfeeding knowledge data and evaluation of the online BT was pre and posttest study. Eighty six undergraduate nursing students completed the online BT using Blackboard Learn. The online component of the BT consisted of five modules with a combined length of approximately 16 hours. After the completion of the modules, the students increased their levels of knowledge related to breastfeeding and the majority believed that they were fully able to perform skills to support breastfeeding. The results of this study indicate that a successful BT for nursing students can be effectively designed, which can in the future be disseminated to other healthcare providers and students. In addition, this online BT was cost-efficient and effective in improving students' knowledge and skills to support breastfeeding.

Extra fluids for breastfeeding mothers for increasing milk production

BACKGROUND

Breastfeeding is known to be the biological norm. Despite this, many women wean their babies because of perceived insufficient breast milk production. Mothers are sometimes advised to increase their fluid intake in the hope that this could improve breast milk production. The effect of extra fluid on human breast milk production is not well established, however.

OBJECTIVES

To assess the effect of extra fluid for breastfeeding mothers on milk production/supply and infant growth.

SEARCH METHODS

We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (27 April 2014), MEDLINE (1966 to 27 April 2014), African Journals Online (27 April 2014) and reference lists of retrieved studies.

SELECTION CRITERIA

Randomised controlled trials and quasi-randomised controlled trials on extra fluids for breastfeeding mothers.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed the potential studies for inclusion and assessed trial quality.

MAIN RESULTS

Five trial reports were retrieved using the search strategies. Four trials were excluded. We did not identify any randomised controlled trials for inclusion but we included one quasi-randomised study (involving 210 women) that evaluated the effect of extra fluid for breastfeeding mothers on breastfeeding outcomes. The study was considered to be at a high risk of bias. Only one of this review's primary outcomes was reported (breast milk production (as defined by the trialist)) but data were not in a suitable format for analysis (no standard deviations or standard errors were reported). The trialist reported that advising women to drink extra fluids did not improve breast milk production. No data were reported for the review's other primary outcomes: satisfactory weight gain in the infant (as defined by the trialists) and duration of exclusive breastfeeding (months). Similarly, no data were reported for any of this review's secondary outcomes: duration of any breastfeeding; mother's satisfaction with breastfeeding; hydration in mother; dehydration in the infant; or episodes of gastrointestinal illness.

AUTHORS' CONCLUSIONS

This review only identified one small quasi-randomised controlled trial of low quality and high risk of bias. The study provided limited data on only one of this review's primary outcomes, breast milk production, but the data were not reported in a format that permitted further analysis. The trialist reported that extra fluids did not improve breast milk production. However, this outcome was measured by using test feeds (also known as test weighing). In the 1950s, when the study was conducted, it was common for babies in developed countries to be weighed before and after a feed, known as test weighing or test feeding. However, this practice is not now routinely practiced for term infants due to concerns about lack of precision as a measure of breast milk production. The included study did not report on this review's other primary outcomes (satisfactory weight gain in the infant or duration of exclusive breastfeeding) nor any of the review's secondary outcomes.The effect of additional fluids for breastfeeding mothers remains unknown, due to a lack of well-conducted trials. However, because the physiological basis for any such improvement remains unclear, the conduct of further clinical trials may not be a priority. There is not enough evidence to support an increased fluid intake beyond what breastfeeding mothers are likely to require to meet their physiological needs.

Applying a knowledge translation model to the uptake of the Baby Friendly Health Initiative in the Australian health care system

BACKGROUND

The Baby Friendly Hospital Initiative is a global, evidence-based, public health initiative. The evidence underpinning the Initiative supports practices promoting the initiation and maintenance of breastfeeding and encourages women's informed infant feeding decisions. In Australia, where the Initiative is known as the Baby Friendly Health Initiative (BFHI) the translation of evidence into practice has not been uniform, as demonstrated by a varying number of maternity facilities in each State and Territory currently accredited as 'baby friendly'. This variance has persisted regardless of BFHI implementation in Australia gaining 'in principle' support at a national and governmental level as well as inclusion in health policy in several states. There are many stakeholders that exert an influence on policy development and health care practices.

AIM

Identify a theory and model to examine where and how barriers occur in the gap between evidence and practice in the uptake of the BFHI in Australia.

RESULTS

Knowledge translation theory and the research to practice pipeline model are used to examine the identified barriers to BFHI implementation and accreditation in Australia.

CONCLUSION

Australian and international studies have identified similar issues that have either enabled implementation of the BFHI or acted as a barrier. Knowledge translation theory and the research to practice pipeline model is of practical value to examine barriers. Recommendations in the form of specific targeted strategies to facilitate knowledge transfer and supportive practices into the Australian health care system and current midwifery practice are included.

Motivational interviewing improves exclusive breastfeeding in an Australian randomised controlled trial

AIM

To increase maintenance of breastfeeding through improved primary care support.

METHOD

A cluster randomised controlled trial recruited 15 rural family doctor's offices and 330 women who were currently breastfeeding took part. Eight practices formed the intervention group (154 women) and seven formed the control group (176 women). The practice nurses who provided the intervention used a specially designed motivational flowchart to speak to the mothers when they brought their child for immunisation at 2, 4 and 6 months. The nurses also attended preparatory workshops on breastfeeding management, counselling skills, motivational interviewing and reflective practice and were given resources and support. Breastfeeding rates were measured at 4 and 6 months.

RESULTS

Randomisation equally distributed all measured variables except prenatal intentions to rejoin employment within 12 months (70% intervention, 56% control, p < 0.05). After adjustment, the 4-month figures showed significantly higher rates of exclusive breastfeeding (OR 1.88; 95%CI 1.01-3.50; p = 0.047) and full breastfeeding (water/juice allowed) (OR 1.95; 95%CI 1.03-3.69; p = 0.04) in the intervention group. There were no differences at 6 months.

CONCLUSION

A motivational interviewing intervention by primary care health professionals who have undertaken a replicable training programme is feasible and effective in increasing exclusive breastfeeding and full/predominant breastfeeding at 4 months.

Breastfeeding knowledge, attitudes, prior exposure, and intent among undergraduate students

BACKGROUND

Understanding breastfeeding knowledge, attitudes, and exposures among nonpregnant youth who are likely to be future parents may provide significant pathways to successfully increasing breastfeeding as the normal, accepted way of feeding infants. However, based on a recent review of the literature, only 3 studies have assessed these factors in nonpregnant, young adults in the United States in the past 10 years.

OBJECTIVE

The objective of this study was to gather more recent data regarding breastfeeding knowledge, attitudes, and prior exposure among undergraduate university students.

METHODS

This was a cross-sectional survey, conducted in November 2010. A convenience sample, consisting of undergraduates in attendance in 2 sections of an introductory nutrition class at a large research university, was used for this project (N = 248).

RESULTS

Breastfeeding knowledge was relatively good. However, overall breastfeeding attitudes were more neutral, which appeared to be explained by the belief that breastfeeding is painful, restrictive, and inconvenient, both in general and specifically for the working mother. Though support for breastfeeding in public was low, men were significantly less likely than women to believe it to be embarrassing or unacceptable. In addition, breastfeeding attitudes were more positive among older students and those who were breastfed as infants. Those who were breastfed as infants were also significantly more likely to intend to breastfeed future children.

CONCLUSIONS

Though this sample indicates good breastfeeding knowledge, attitudes were more neutral, and support for breastfeeding in public appears low. This finding is contradictory and warrants further exploration.

Breast milk banking: current opinion and practice in Australian neonatal intensive care units

AIM

To find out the knowledge and attitudes of health-care professionals (HCPs) in Australian neonatal intensive care units (NICUs) towards breast milk banking (BMBg) and pasteurised donated breast milk (PDBM).

METHODS

Cross-sectional structured survey of HCPs in all 25 NICUs in Australia.

RESULTS

Response rate was 43.4% (n= 358 of 825). Participants included nurses and midwives (291, 81.3%) and the remainder were neonatologists and neonatal trainees (67, 18.7%). A variable number of HCPs agreed that PDBM would decrease the risk of necrotising enterocolitis (81%) and allergies (48.9%), 8.4% thought PDBM will carry risk of infections and 78.8% agreed that PDBM is preferable over formula, but only 67.5% thought that establishing breast milk banks (BMBs) are justifiable. Significant differences were found between doctors and nurses/midwives, with 19.4% of doctors compared with 5.8% of nurses/midwives agreed that PDBM carried an increased risk of infection. Although, over 90% of nurses/midwives and 70% of doctors agreed that the donation of breast milk is important, only 71% of nurses/midwives and 52.2% of doctors thought that setting up a BMB was justifiable.

CONCLUSION

The opinions about BMBg differ widely between HCPs; however, the majority support the practice. HCPs had different knowledge gaps in regard to BMBg. Nurses/midwives positively view the practice of BMBg more strongly compared with neonatologists.

Knowledge, misconceptions, and future intentions towards breastfeeding among female university students in Kuwait

A cross-sectional study using a self-administered questionnaire was conducted on female university students (N = 1106) to explore their knowledge and misconceptions on breastfeeding. Most participants recognized the benefits of breastfeeding, but only a few were aware of the recommendation for exclusive breastfeeding in the first 6 months of life. Misconceptions were common; 66%, 60%, and 55% of participants thought mothers should temporarily stop breastfeeding if they had a fever, skin rash, or sore throat, respectively. Approximately 20% thought mothers should stop breastfeeding if the child had diarrhea, vomiting, or skin rash. Support of breastfeeding in public places was low, but 38% supported breastfeeding in female prayer rooms in public places. Efforts should be made to correct common misconceptions on breastfeeding and increase the support of breastfeeding in public places among university students. Female prayer rooms that exist in all public places in Kuwait can be used to promote breastfeeding in public places in Kuwait.

Chronic disease and infant nutrition: is it significant to public health?

OBJECTIVE

To assess the public health significance of premature weaning of infants from breast milk on later-life risk of chronic illness.

DESIGN

A review and summary of recent meta-analyses of studies linking premature weaning from breast milk with later-life chronic disease risk is presented followed by an estimation of the approximate exposure in a developed Western country, based on historical breast-feeding prevalence data for Australia since 1927. The population-attributable proportion of chronic disease associated with current patterns of artificial feeding in infancy is estimated.

RESULTS

After adjustment for major confounding variables, current research suggests that the risks of chronic disease are 30-200 % higher in those who were not breast-fed compared to those who were breast-fed in infancy. Exposure to premature weaning ranges from 20 % to 90 % in post-World War II age cohorts. Overall, the attributable proportion of chronic disease in the population is estimated at 6-24 % for a 30 % exposure to premature weaning.

CONCLUSIONS

Breast-feeding is of public health significance in preventing chronic disease. There is a small but consistent effect of premature weaning from breast milk in increasing later-life chronic disease risk. Risk exposure in the Australian population is substantial. Approximately 90 % of current 35-45-year-olds were weaned from breast-feeding by 6 months of age. Encouraging greater duration and exclusivity of breast-feeding is a potential avenue for reducing future chronic disease burden and health system costs.

The impact of article titles on citation hits: an analysis of general and specialist medical journals

OBJECTIVES

Most published articles are not cited and citation rates depend on many variables. We hypothesized that specific features of journal titles may be related to citation rates.

DESIGN

We reviewed the title characteristics of the 25 most cited articles and the 25 least cited articles published in 2005 in general and specialist medical journals including the Lancet, BMJ and Journal of Clinical Pathology. The title length and construction were correlated to the number of times the papers have been cited to May 2009.

SETTING

Retrospective review of a scientific database.

PARTICIPANTS

None.

MAIN OUTCOME MEASURES

Citation rate.

RESULTS

The number of citations was positively correlated with the length of the title, the presence of a colon in the title and the presence of an acronym. Factors that predicted poor citation included reference to a specific country in the title.

CONCLUSIONS

These data suggest that the construction of an article title has a significant impact on frequently the paper is cited. We hypothesize that this may be related to the way electronic searches of the literature are undertaken.

Lifetime health outcomes of breast-feeding: a comparison of the policy documents of five European countries

OBJECTIVE

To (i) identify and describe prevailing infant feeding policy documents in five diverse European countries; (ii) analyse types of health outcomes for the infant that are associated with feeding breast milk rather than formula milk in the documents of different countries; and (iii) assess the extent to which documents reflect the WHO global recommendation of exclusive breast-feeding for 6 months.

DESIGN

Documentary review and analysis.

SETTING

Five geographically dispersed countries of Europe (England, Finland, Germany, Hungary and Spain).

SUBJECTS

Policy documents on infant feeding were identified; statements that linked choice between breast- and formula-feeding to a health outcome for the infant were extracted.

RESULTS

Twenty-six documents (varied authorships, dates, length and character) were identified: four from England; two from Finland; nine from Germany; six from Hungary; and five from Spain. There was no consistency in the way in which health outcomes were cited as factors in the recommendations for breast- rather than formula-feeding. Seven documents contained no reference to the health implications of infant feeding choice. Of 203 statements in remaining documents citing health outcomes, 24.1 % mentioned general health effects, 32.5 % protection against infections, 31.5 % long-term conditions (e.g. diabetes, CVD) and 11.8 % mentioned allergy. Health outcomes were linked to exclusive breast-feeding in only 25 % of statements.

CONCLUSIONS

Policy documents in the study countries varied in the extent to which they reflect the health outcomes for the baby of breast-feeding, and this may limit effective promotion by health professionals. There is scope to improve the process of bringing evidence and recommendations into policy documents.

What are the risks associated with formula feeding? A re-analysis and review

BACKGROUND

Most infant feeding studies present infant formula use as "standard" practice, supporting perceptions of formula feeding as normative and hindering translation of current research into counseling messages supportive of exclusive breastfeeding. To promote optimal counseling, and to challenge researchers to use exclusive breastfeeding as the standard, we have reviewed the scientific literature on exclusive breastfeeding and converted reported odds ratios to allow discussion of the "risks" of any formula use.

METHODS

Studies indexed in PubMed that investigated the association between exclusive breastfeeding and otitis media, asthma, types 1 and 2 diabetes, atopic dermatitis, and infant hospitalization secondary to lower respiratory tract diseases were reviewed. Findings were reconstructed with exclusive breastfeeding as the standard, and levels of significance calculated.

RESULTS

When exclusive breastfeeding is set as the normative standard, the re-calculated odds ratios communicate the risks of any formula use. For example, any formula use in the first 6 months is significantly associated with increased incidence of otitis media (OR: 1.78, 95% CI: 1.19, 2.70 and OR: 4.55, 95% CI: 1.64, 12.50 in the available studies; pooled OR for any formula in the first 3 mo: 2.00, 95% CI: 1.40, 2.78). Only shorter durations of exclusive breastfeeding are available to use as standards for calculating the effect of "any formula use" for type 1 diabetes, asthma, atopic dermatitis, and hospitalization secondary to lower respiratory tract infections.

CONCLUSIONS

Exclusive breastfeeding is an optimal practice, compared with which other infant feeding practices carry risks. Further studies on the influence of presenting exclusive breastfeeding as the standard in research studies and counseling messages are recommended.
