Abstract
The aim of this study was to examine the psychometric properties of the 11-item Breast Milk Expression Experience Scale and determine the level of breast milk expression experience of mothers after preterm delivery in Turkey. 165 mothers who agreed to participate between February 2019 and March 2020 used the Breast Milk Expression Experience Scale (BMEE-S). The general Cronbach alpha coefficient was 0.82 for the BMEE-S. The fit indices calculated by confirmatory factor analysis were χ2 (41) = 87.95, p = .00003, χ2/sd = 2.15, GFI = 0.91, NNFI = 0.93, CFI = 0.95, RMSEA = 0.08 and SRMR = 0.078. The BMEE-S three-factor structure was verified by the confirmatory factor analysis. The BMEE-S was a valid and reliable instrument for mothers of preterm infants. Multiparity and high-risk pregnancy history negatively affected the milk expression experience, whereas spousal support positively affected it.Impact statementWhat is already known on this subject? The risk of infectious diseases, obesity, diabetes, and impaired intellectual development increases in children who do not breast milk (Verduci et al. 2014). International breastfeeding guidelines recommend supporting all mothers to start breastfeeding within one hour of birth, and counselling mothers who are separated from their babies about expressing milk.What the results of this study add? The breast milk expression experience scale is a valid and reliable tool for women who give preterm birth and express milk. The experience of expressing breast milk can affect the amount of milk that passes from mother to baby. Multiparity and high risk pregnancy history of mothers negatively affects the milk expression experience while husband support positively affects the milk expression experience.What the implications are of these findings for clinical practice and/or further research? Our study provides a quantitative examination of the experiences of mothers who are separated from their babies. The BMEE-S should be adapted to different cultures and the experiences of mothers in this process should be determined.

A quantitative study on Muslim milk mother’s understanding of the Islamic concept of wet nursing. PLoS One 2022; 17:e0265592. [PMID: 35587475 PMCID: PMC9119450 DOI: 10.1371/journal.pone.0265592] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2021] [Accepted: 03/05/2022] [Indexed: 11/18/2022] Open
Abstract
Background
The practice of wet nursing or breastfeeding another woman’s child in Malaysia, especially among Muslim mothers, is on the rise. This is due to the emergence of public awareness of the benefits of breast milk to children. However, it is claimed that some mothers do not have a clear understanding of the Islamic rulings concerning wet nursing, especially those related to mahram (prohibition to marry), nasab (lineage) and inheritance. Hence, the purpose of this study is to examine the level of understanding of the legal implications of wet nursing and the factors influencing the practice among Muslim mothers who have practiced breastfeeding.
Methods
This was a cross-sectional descriptive study that was conducted between January and July 2019. This study was conducted with 100 Muslim mothers who had breastfed others’ child(ren) in Selangor. Data were obtained using a validated questionnaire (Cronbach’s alpha = 0.8) and processed using the Statistical Package for the Social Sciences (SPSS) software.
Results
The results show that the majority of the respondents understand the basic Islamic rulings on wet nursing, especially on the persons prohibited to marry, conditions and feeding method. However, the respondents need to further understand the rulings related to nasab (lineage), guardianship and inheritance involving the milk child. Various factors that have influenced wet nursing in society were also found.
Conclusions
This study has significant implications for the need to have more activities to create awareness and enhance the understanding related to wet nursing among Muslim women in society. Therefore, more research studies related to wet nursing and the impact of the practice should be conducted to offer better solutions to society.

J Midwifery Womens Health 2021; 66:641-655. [PMID: 34423557 DOI: 10.1111/jmwh.13243] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2020] [Revised: 04/07/2021] [Accepted: 04/11/2021] [Indexed: 11/26/2022]
Abstract
INTRODUCTION Returning to paid employment is one of the reasons women stop breastfeeding earlier than they planned to. This systematic review aimed to provide insight into the experiences and views of women and employers on breastfeeding and returning to paid employment, with findings used to inform practice and policy. METHODS The review was guided by the Joanna Briggs Institute (JBI) methodology for systematic reviews of qualitative evidence. Medline, CINAHL, PsycINFO, and Web of Science databases were searched for studies published in English. JBI's meta-aggregative approach informed data analysis. The studies in this analysis included women who stopped breastfeeding before, and those who continued breastfeeding after, returning to paid employment and the employers, work managers, or supervisors of women who continued breastfeeding after returning to paid employment. RESULTS Twenty-six articles presenting findings from 25 studies were included and critically appraised. Synthesized findings showed that women experienced physical and emotional difficulties and described gender and employment inequalities in accessing and receiving the support they needed. Women reported that the importance of their own motivation and having workplace legislation in place facilitated breastfeeding during employment. Support from employers, colleagues, and family members, as well as access to convenient child care, helped women continue breastfeeding on return to paid employment. Employers' personal experiences influenced their views on breastfeeding and working, and the need for more education and communication between employers and employers on breastfeeding in the workplace was recognized. DISCUSSION Support from family, work colleagues, and employers was important to reduce the physical and emotional challenges women experienced when combing breastfeeding with return to paid employment. Gender inequalities, especially in low- and middle-income countries, in accessing support exacerbated the difficulties women experienced. Limited data were identified regarding employers' experiences and views, suggesting an urgent need for further research to explore employers' and work colleagues' experiences and views.

Abstract
BACKGROUND Breastfeeding is widely recognized as the optimal and natural method of feeding infants. However, there are obstacles that can limit exclusive breastfeeding practices during the first 6 months of an infant's life. This study aimed to determine the prevalence of unsuccessful exclusive breastfeeding and its associated factors among mothers who work as healthcare providers at Universiti Sains Malaysia Hospital. METHODS A cross-sectional study was conducted among 295 medical doctors and staff nurses from June to December 2015. Simple random sampling was applied. The data were collected using a self-administered questionnaire and analyzed using IBM SPSS ver. 22.0 (IBM Corp., Armonk, NY, USA). Descriptive statistics and logistic regression analysis were performed. RESULTS The prevalence of unsuccessful exclusive breastfeeding among the study participants was 58.3%. Mothers who preferred formula milk (odds ratio [OR], 4.40; 95% confidence interval [CI], 1.45-13.31) delivered via lower segment cesarean section (OR, 2.31; 95% CI, 1.07-4.98) and produced inadequate breast milk (OR, 4.06; 95% CI, 2.40- 6.89) were significantly associated with unsuccessful exclusive breastfeeding. CONCLUSION The prevalence of unsuccessful exclusive breastfeeding among the study participants was high. Maternal characteristics such as preference towards formula milk, mode of delivery and adequacy of breast milk must be assessed to prevent unsuccessful exclusive breastfeeding among healthcare providers.

Abstract
BACKGROUND Although substantial evidence exists on factors that influence exclusive breastfeeding, there is a general lack of qualitative studies that examine how specific workplace factors constrain or promote exclusive breastfeeding among working mothers. The current study therefore examines working mothers' experience of exclusive breastfeeding, laying emphasis on the influence of workplace factors on working mothers' decision to exclusively breastfeed their babies. METHODS The study uses a qualitative research approach and a three-stage purposive sampling procedure to select 20 mothers from 10 organizations in five industries for in-depth interviews on their exclusive breastfeeding experience. Data collected from the interviews were analysed using content analysis, with two major themes emerging for discussion. RESULTS The results suggest that two major factors influence exclusive breastfeeding among working mothers: practice of exclusive breast feeding (knowledge and understanding of exclusive breastfeeding, and experience in exclusive breastfeeding) and workplace factors (length of maternity leave, closing time, absence of maternity policy in organizations, inadequate institutional support and family work-life balance). CONCLUSION The results of the study suggest that workplace factors play an equally crucial role in the decision by mothers to exclusively breastfeed their babies. Thus, in the special case of working mothers where breastfeeding prevalence is low, the findings of this study can be crucial in evolving appropriate policies to support working mothers in their effort to exclusively breastfeed their babies.

Abstract
BACKGROUND Breastfeeding is important, however not all infants can feed at the breast and methods of expressing milk need evaluation. OBJECTIVES To assess acceptability, effectiveness, safety, effect on milk composition, contamination and costs of methods of milk expression. SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (21 March 2016), handsearched relevant journals and conference proceedings, and contacted experts in the field to seek additional published or unpublished studies. We also examined reference lists of all relevant retrieved papers. SELECTION CRITERIA Randomised and quasi-randomised trials comparing methods at any time after birth. DATA COLLECTION AND ANALYSIS Three review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy. MAIN RESULTS This updated review includes 41 trials involving 2293 participants, with 22 trials involving 1339 participants contributing data for analysis. Twenty-six of the trials referred to mothers of infants in neonatal units (n = 1547) and 14 to mothers of healthy infants at home (n = 730), with one trial containing mothers of both neonatal and healthy older infants (n = 16). Eleven trials compared one or more types of pump versus hand expression and 14 studies compared one type of pump versus another type of pump, with three of these studies comparing both hand expression and pump types. Twenty studies compared a specific protocol or adjunct behaviour including sequential versus simultaneous pumping protocols, pumping frequency, provision of an education and support intervention, relaxation, breast massage, combining hand expression with pumping and a breast cleansing protocol.Due to heterogeneity in participants, interventions, and outcomes measured or reported, we were unable to pool findings for most of the specified outcomes. It was not possible therefore to produce a 'Summary of findings' table in this update. Most of the included results were derived from single studies. Trials took place in 14 countries under a variety of circumstances and were published from 1982 to 2015. Sixteen of the 30 trials that evaluated pumps or products had support from the manufacturers. The risk of bias of the included studies was variable. Primary outcomesOnly one of the 17 studies examining maternal satisfaction/acceptability with the method or adjunct behaviour provided data suitable for analysis. In this study, self-efficacy was assessed by asking mothers if they agreed or disagreed with the following statement: 'I don't want anyone to see me (hand expressing/pumping)'. The study found that mothers who were using the electric pump were more likely to agree with the statement compared to mothers hand expressing, (mean difference (MD) 0.70, 95% confidence interval (CI) 0.15 to 1.25; P = 0.01, participants = 68). Mothers who were hand expressing reported that the instructions for expression were clearer compared to the electric pump, (MD -0.40, 95% CI -0.75 to -0.05; P = 0.02, participants = 68). Descriptive reporting of satisfaction in the other studies varied in the measures used, did not indicate a clear preference for one pump type, although there was satisfaction with some relaxation and support interventions.We found no clinically significant differences between methods related to contamination of the milk that compared any type of pump to hand expression (risk ratio (RR) 1.13, 95% CI 0.79 to 1.61; P = 0.51, participants = 28), manual pump compared to hand expression, (MD 0.20, 95% CI -0.18 to 0.58; P = 0.30, participants = 142) a large electric pump compared to hand expression (MD 0.10, 95% CI -0.29 to 0.49; P = 0.61, participants = 123), or a large electric pump compared to a manual pump (MD -0.10, 95% CI -0.46 to 0.26; P = 0.59, participants = 141).The level of maternal breast or nipple pain or damage was similar in comparisons of a large electric pump to hand expression (MD 0.02, 95% CI -0.67 to 0.71; P = 0.96, participants = 68). A study comparing a manual and large electric pump, reported sore nipples in 7% for both groups and engorgement in 4% using a manual pump versus 6% using an electric pump; and in one study no nipple damage was reported in the hand-expression group, and one case of nipple damage in each of the manual pump and the large electric pump groups.One study examined adverse effects on infants, however as the infants did not all receive their mothers' expressed milk, we have not included the results. Secondary outcomesThe quantity of expressed milk obtained was increased, in some studies by a clinically significant amount, in interventions involving relaxation, music, warmth, massage, initiation of pumping, increased frequency of pumping and suitable breast shield size. Support programmes and simultaneous compared to sequential pumping did not show a difference in milk obtained. No pump consistently increased the milk volume obtained significantly.In relation to nutrient quality, hand expression or a large electric pump were found to provide higher protein than a manual pump, and hand expression provided higher sodium and lower potassium compared to a large electric pump or a manual pump. Fat content was higher with breast massage when pumping; no evidence of difference was found for energy content between methods.No consistent effect was found related to prolactin change or effect on oxytocin release with pump type or method. Economic aspects were not reported. AUTHORS' CONCLUSIONS The most suitable method for milk expression may depend on the time since birth, purpose of expression and the individual mother and infant. Low-cost interventions including initiation of milk expression sooner after birth when not feeding at the breast, relaxation, massage, warming the breasts, hand expression and lower cost pumps may be as effective, or more effective, than large electric pumps for some outcomes. Variation in nutrient content across methods may be relevant to some infants. Small sample sizes, large standard deviations, and the diversity of the interventions argue caution in applying these results beyond the specific method tested in the specific settings. Independently funded research is needed for more trials on hand expression, relaxation and other techniques that do not have a commercial potential.

Abstract
Background In Ghana, periodic national surveys report the practice of exclusive breastfeeding (EBF) in the general population to be over 50 %. However, little is known about EBF among professional working mothers, particularly its duration after maternity leave. Female workers are entitled to 12 weeks (84 days) of maternity leave with full pay in Ghana, and this can be extended by two additional weeks in case of a caesarean or abnormal delivery. This study assessed the prevalence of EBF, as well as factors associated with the practice among professional working mothers in one of the ten regional capitals of Ghana. Methods The study was descriptive cross-sectional in design and employed a multi-stage sampling technique to sample 369 professional working mothers. The study was planned and implemented between January to July 2015. Study-specific structured questionnaires were used in the data collection over a period of one month. Some factors including demographic characteristics, types of facilities available at workplace to support breastfeeding, challenges to exclusive breastfeeding at the workplace and mother’s knowledge base on EBF, were assessed. Exclusive breastfeeding is defined as feeding infants with only breast milk, without supplemental liquids or solids except for liquid medicine and vitamin or mineral supplements. Results There was a near universal awareness of exclusive breastfeeding among respondents (99 %). Even though most mothers initiated breastfeeding within an hour of delivery (91 %), the EBF rate at six months was low (10.3 %). The study identified three elements as determinants of EBF; Those who did not receive infant feeding recommendation from health workers were less likely to practice exclusive breastfeeding (Adjusted Odds Ratio [AOR] 0.45; 95 % Confidence Interval [CI] 0.27, 0.77), mothers who had shorter duration of maternity leave were less likely to practice exclusive breastfeeding (AOR 0.09; 95 % CI 0.02, 0.45), and those who had a normal delivery were almost 10 times as likely to practice exclusive breastfeeding (AOR 9.02; 95 % CI 2.85, 28.53). Conclusion Given the high breastfeeding initiation, but low EBF continuation rate among professional working mothers, improved policies around maternity leave and breastfeeding friendly work environments are needed.

Abstract
AIM To describe the enablers and barriers working women experience in continuing breast milk feeding after they return to work postpartum in urban Malaysia. BACKGROUND In Malaysia, urban working women have low rates of breastfeeding and struggle to achieve the recommended 6 months exclusive breastfeeding. DESIGN A qualitative enquiry based on a phenomenological framework and multiple methods were used to explore women's experiences in depth. METHODS Multiple qualitative methods using face-to-face interview and participant diary were used. Data collection took place in urban suburbs around Penang and Klang Valley, Malaysia from March-September 2011. Participants were 40 employed women with infants less than 24 months. FINDINGS Only 11 of the participants worked from home. Based on the women's experiences, we categorized them into three groups: 'Passionate' women with a strong determination and exclusively breastfed for 6 months, 'Ambivalent' women who initiated breastfeeding, but were unable to sustain exclusive breastfeeding after returning to work and 'Equivalent' women who introduced infant formula prior to returning to work. CONCLUSION Passion and to a lesser extent intention, influenced women's choice. Women's characteristics played a greater role in their infant feeding outcomes than their work environment.

Abstract
BACKGROUND This is an update of a 2008 Cochrane review. Breastfeeding is important. However, not all infants can feed at the breast and methods of expressing milk need evaluation. OBJECTIVES To assess acceptability, effectiveness, safety, effect on milk composition, contamination and cost implications of methods of milk expression. SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (March 2014), CINAHL (1982 to March 2014), conference proceedings, secondary references and contacted researchers. SELECTION CRITERIA Randomised and quasi-randomised trials comparing methods at any time after birth. DATA COLLECTION AND ANALYSIS Three authors independently assessed trials, extracted data and assessed risk of bias. MAIN RESULTS This updated review includes 34 studies involving 1998 participants, with 17 trials involving 961 participants providing data for analysis. Eight studies compared one or more types of pump versus hand expression and 14 studies compared one type of pump versus another type of pump, with three of these studies comparing both hand expression and multiple pump types. Fifteen studies compared a specific protocol or adjunct behaviour including sequential versus simultaneous pumping protocols (five studies), pumping > 4 times per day versus < 3 times per day (one study), provision of a milk expression education and support intervention to mothers of preterm infants versus no provision (one study), provision of audio/visual relaxation to mothers of preterm infants versus no specific relaxation (two studies), commencing pumping within one hour of delivery versus between one to six hours (one study), breast massage before or during pumping versus no massage (two studies, of which one also tested a second behaviour), therapeutic touch versus none (one study), warming breasts before pumping versus not warming breasts (one study), combining hand expression with pumping versus pumping alone (one study) and a breast cleansing protocol versus no protocol (one study).There were insufficient comparable data on outcomes to undertake meta-analysis and data reported relates to evidence from single studies.Only one of the 17 studies examining maternal satisfaction/acceptability provided data in a way that could be analysed, reporting that mothers assigned to the pumping group had more agreement with the statement 'I don't want anyone to see me pumping' than mothers in the hand expression group and the statement 'I don't want anyone to see me hand expressing' (n = 68, mean difference (MD) -0.70, 95% confidence interval (CI) -1.25 to -0.15, P = 0.01), and that mothers found instructions for hand expression were clearer than for pumping (n = 68, MD 0.40, 95% CI 0.05 to 0.75, P = 0.02). No evidence of a difference was found between methods related to adverse effects of milk contamination (one study, n = 28, risk ratio (RR) 0.89, 95% CI 0.62 to 1.27, P = 0.51), (one study, n = 142 milk samples, MD 0.20, 95% CI -0.18 to 0.58, P = 0.30), (one study, n = 123 milk samples, MD 0.10, 95% CI -0.29 to 0.49, P = 0.61), (one study, n = 141 milk samples, MD -0.10, 95% CI -0.46 to 0.26, P = 0.59 ); or level of maternal breast or nipple pain or damage (one study, n = 68, MD 0.02, 95% CI -0.67 to 0.71, P = 0.96).For the secondary outcomes, greater volume was obtained when mothers with infants in a neonatal unit were provided with a relaxation tape or music-listening interventions to use while pumping, when the breasts was warmed before pumping or massaged while pumping.Initiation of milk pumping within 60 minutes of birth of a very low birthweight infant obtained higher mean milk quantity in the first week than the group who initiated pumping later. No evidence of difference in volume was found with simultaneous or sequential pumping or between pumps studied. Differences between methods was found for sodium, potassium, protein and fat constituents; no evidence of difference was found for energy content.No consistent effect was found related to prolactin change or effect on oxytocin release with pump type or method. Economic aspects were not reported.Most studies were classified as unclear or low risk of bias. Most studies did not provide any information regarding blinding of outcome assessment. Fifteen of the 25 studies that evaluated pumps or products had support from the manufacturers. AUTHORS' CONCLUSIONS The most suitable method for milk expression may depend on the time since birth, purpose of expression and the individual mother and infant. Low-cost interventions including early initiation when not feeding at the breast, listening to relaxation music, massage and warming of the breasts, hand expression and lower cost pumps may be as effective, or more effective, than large electric pumps for some outcomes. Small sample sizes, large standard deviations, and the diversity of the interventions argue caution in applying these results beyond the specific method tested in the specific settings.
