    The health benefits of breastfeeding to infants and mothers have been well recognised. This study applies linear regression analysis to assess the determinants of breastfeeding duration of first born using data from the Second Malaysian Family Life Survey. The proportion of women who breastfed their first child is 82 percent, of which 97 percent reported their breastfeeding duration. The distribution of breastfeeding duration has a mean of 5.7 months and a median of two months. Important determinants of breastfeeding duration include maternal age, ethnicity, period of first birth, husband's occupation and work status of the woman.

    Although extensively collected, data on people's reasons for their behaviour provided retrospectively have been met with some scepticism on the grounds that they may be subject to biases and errors that jeopardize their usefulness. This study investigates, for a sample of 1,327 births, the reliability with which women in Peninsular Malaysia recalled, at intervals 12 years apart, reasons for not initiating or for stopping breastfeeding less than 3 months after a birth. Overall, we find low to moderate reliability of recall. Levels of reliability are relatively high for some reasons (the child died and no or insufficient milk) but low for some others (child ill, breastfeeding inconvenient). Results from selection models show that reliability does not vary with the length of time since the child's birth but is inversely related to socio-economic status (proxied by education and employment). Social status, social norms, and health-related factors appear to be significant influences on women's consistency of reporting.

    PROBLEM: Research suggests that breastfeeding self-efficacy (i.e., a mother's perceived ability and confidence to breastfeed her new-born) is associated with body image experiences and wider psychosocial factors. However, much of this work is focused on negative body image and has relied on samples from predominantly Westernised, industrialised nations.

    BACKGROUND: To extend knowledge, we sought to examine the extent to which indices of positive body image (body appreciation), negative body image (body dissatisfaction, breast size dissatisfaction), and psychosocial factors (body acceptance by others, postpartum partner support) are associated with breastfeeding self-efficacy in sample of mothers from Israel.

    HYPOTHESIS: We hypothesised that body appreciation, body dissatisfaction, breast size dissatisfaction, body acceptance by others, and postpartum partner support would each be significantly associated with breastfeeding self-efficacy in Israeli mothers.

    METHOD: A total of 352 mothers from Israel, with an infant aged six months or younger, were asked to complete an online survey that measured the aforementioned constructs.

    FINDINGS: Correlational and linear model analyses indicated that only body appreciation was significantly associated with breastfeeding self-efficacy. Body acceptance by others was significantly associated with breastfeeding self-efficacy in correlational but not regression analyses. These effects were consistent across primiparous and multiparous mothers.

    DISCUSSION: In Israeli mothers, at least, a limited set of body image and body image-related indices appear to be associated with breastfeeding self-efficacy.

    CONCLUSION: Overall, these findings suggest that positive body image may be associated with breastfeeding self-efficacy in women from Israel, though more research is needed.

    BACKGROUND: To successfully initiate and maintain breastfeeding for a longer duration, the World Health Organization's Ten Steps to Successful Breastfeeding recommends total avoidance of artificial teats or pacifiers for breastfeeding infants. Concerns have been raised that offering the pacifier instead of the breast to calm the infant may lead to less frequent episodes of breastfeeding and as a consequence may reduce breast-milk production and shorten duration of breastfeeding.

    OBJECTIVES: To assess the effect of restricted versus unrestricted pacifier use in healthy full-term newborns whose mothers have initiated breastfeeding and intend to exclusively breastfeed, on the duration of breastfeeding, other breastfeeding outcomes and infant health.

    SEARCH METHODS: We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 June 2016) and reference lists of retrieved studies.

    SELECTION CRITERIA: Randomised and quasi-randomised controlled trials comparing restricted versus unrestricted pacifier use in healthy full-term newborns who have initiated breastfeeding.

    DATA COLLECTION AND ANALYSIS: Two review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy. The quality of the evidence was assessed using the GRADE approach.

    MAIN RESULTS: We found three trials (involving 1915 babies) for inclusion in the review, but have included only two trials (involving 1302 healthy full-term breastfeeding infants) in the analysis. Meta-analysis of the two combined studies showed that pacifier use in healthy breastfeeding infants had no significant effect on the proportion of infants exclusively breastfed at three months (risk ratio (RR) 1.01; 95% confidence interval (CI) 0.96 to 1.07, two studies, 1228 infants), and at four months of age (RR 1.01; 95% CI 0.94 to 1.09, one study, 970 infants, moderate-quality evidence), and also had no effect on the proportion of infants partially breastfed at three months (RR 1.00; 95% CI 0.98 to 1.02, two studies, 1228 infants), and at four months of age (RR 0.99; 95% CI 0.97 to 1.02, one study, 970 infants). None of the included trials reported data on the other primary outcomes, i.e. duration of partial or exclusive breastfeeding, or secondary outcomes: breastfeeding difficulties (mastitis, cracked nipples, breast engorgement); infant's health (dental malocclusion, otitis media, oral candidiasis; sudden infant death syndrome (SIDS)); maternal satisfaction and level of confidence in parenting. One study reported that avoidance of pacifiers had no effect on cry/fuss behavior at ages four, six, or nine weeks and also reported no effect on the risk of weaning before age three months, however the data were incomplete and so could not be included for analysis.

    AUTHORS' CONCLUSIONS: Pacifier use in healthy term breastfeeding infants, started from birth or after lactation is established, did not significantly affect the prevalence or duration of exclusive and partial breastfeeding up to four months of age. Evidence to assess the short-term breastfeeding difficulties faced by mothers and long-term effect of pacifiers on infants' health is lacking.

    Maternal psychological state is recognised to influence lactation success, largely by affecting milk ejection. Thus, increased psychological distress can disrupt milk flow and in the long-term, affect milk synthesis. Conversely, it is possible that milk ejection could be improved by using relaxation therapy during breastfeeding. We performed a systematic review to evaluate the effectiveness of interventions using relaxation therapy to improve breastfeeding outcomes and to assess the consequent impact(s) on infant growth and behaviour. A literature search was performed using the PRISMA guidelines where we included intervention studies (including nonrandomised controlled studies) using relaxation therapy in breastfeeding mothers during the post-natal period. Out of 147 identified records at the initial search, 5 studies were eligible, of which 3 were randomised controlled trials and 2 were nonrandomised or quasi-experimental studies. These studies were conducted in Europe, America, and India and included 311 mother-infant pairs, of which 64 infants were full-term and 247 were premature infants. Relaxation therapy was shown to increase milk yield in mothers of preterm infants in 2 randomised trials, however, the milk sampling protocol for these studies could be questioned. None of the studies investigated the consequent effects on infant outcomes. Overall, limited evidence was found on the effectiveness of relaxation therapy on breast milk composition and infant outcomes. Experimental studies with better standardisation of protocol and robust methodological design are needed to investigate the effectiveness of relaxation therapy on both breastfeeding and infant growth and behavioural outcomes.

    BACKGROUND: Antenatal breastfeeding education (ANBE) is provided to all pregnant women attending Ministry of Health (MOH) clinics and some private health facilities in Malaysia, in line with the WHO/UNICEF Baby-Friendly Hospital Initiative (BFHI). However, the 6 month exclusive breastfeeding prevalence remains relatively low in Malaysia, suggesting that there may be a gap between what is currently taught and what is received by the women.

    OBJECTIVES: To determine how women perceived their ANBE experience in the first 8 weeks postpartum including what was useful and what they would like to have been included, sources of ANBE and infant feeding practices at the time of survey.

    METHODS: Women during their first 8 weeks postpartum who attended MOH clinics in Penang State, Malaysia were surveyed using a self-administered questionnaire in April and May 2015. Categorical responses were presented as numbers and proportions while free text responses were compiled verbatim and categorised into themes. The perceptions of primiparous and multiparous women were compared. Multivariate logistic regression adjusted to known confounders was used to determine if ANBE was associated with exclusive breastfeeding at the time of survey.

    RESULTS: A total of 421 women completed the 15-item questionnaire (84% response rate) of which 282 were complete and available for analysis. Of these, 95% had received ANBE, majority (88%) from MOH clinics. Almost all women found it useful. However, there were areas both in the delivery (e.g. too short) and the content (e.g. nothing new) that were described as not useful; and areas they would like more coverage (e.g. milk expression, storage and overcoming low milk supply). The exclusive breastfeeding prevalence at the time of survey was 61%. ANBE was significantly associated with exclusive breastfeeding even after adjusting for confounders (adjusted odds ratio [aOR] 8.1, 95% confidence interval 1.7, 38.3).

    CONCLUSIONS: ANBE is widely implemented and perceived as useful and may be associated with exclusive breastfeeding. Our findings give insight into content that women would like more of and how delivery of ANBE could be improved, including individualized sessions and communicating at a suitable level and language. Future studies could focus on the quality of ANBE delivery.

    Nearly half of the working population in Malaysia are women, and with only a short period of maternity leave, they may struggle to achieve the recommended 6 months of exclusive breastfeeding. The aim of this paper was to explore the relationship between the timing of return to work and beliefs and breastfeeding practices among women in urban Malaysia. A qualitative inquiry based on a phenomenological framework and multiple methods was used: face-to-face interview, participant diary and researcher field notes. Data collection took place in Penang and the Klang Valley, Malaysia, from March to September 2011. Eligible participants were purposely identified at randomly selected recruitment sites. A thematic analysis method was used to develop the typologies and categories of the findings. A total of 40 working women with a mean age of 32 years (SD 3.4) were interviewed and 15 participated in the diary writing. Most women (75%) returned to work between 2 and 3 months. Only 10% returned to work 4 months or later postpartum, and 15% had an early return to work (defined here as less than 2 months). The women fell into three groups: Passionate women with a strong determination to breastfeed, who exclusively breastfed for 6 months; Ambivalent women, who commenced breastfeeding but were unable to sustain this after returning to work; and Equivalent women, who perceived formula feeding as equally nutritious as breast milk. Although longer maternity leave was very important for Ambivalent women to maintain breastfeeding, it was not as important for the Equivalent or Passionate women. In conclusion, returning earlier was not an absolute barrier to continuing breastfeeding. Instead, a woman's beliefs and perceptions of breastfeeding were more important than the timing of her return to work in determining her ability to maintain breastfeeding or breast milk feeding.

    BACKGROUND: Breastfeeding offers incredible health benefits to both child and mother. It is suggested by World Health Organization that an able mother should practice and maintain exclusive breastfeeding for first six months of her infant's life. The objective of this study was to determine the prevalence and factors associated with exclusive breastfeeding for first six months of an infant's life in Bangladesh.

    METHODS: Data was extracted from Bangladesh Demographic and Health Survey (BDHS-2014). BDHS-2014 collected data from 17,863 Bangladeshi married women in reproductive age from the entire country using two stages stratified cluster sampling. We included only mothers having at least one child currently aged not less than 6 months. Mothers who did not have child to breastfeed, some incomplete information and missing samples were excluded from the data set and consequently 3541 mothers were considered in the present study. Chi-square test, binary logistic regression models were used in this study.

    RESULTS: The prevalence of exclusive breastfeeding (EBF) for first six months of an infant's life in Bangladesh was 35.90%. Binary multivariable logistic regression model demonstrated that relatively less educated mothers were more likely to exclusively breastfeed their children than higher educated mothers.

    BACKGROUND: Postnatal depression is a disorder that can lead to serious consequences for both the mother and infant. Despite the extensively documented health benefits of breastfeeding, its association with postnatal depression remains uncertain.
    OBJECTIVE: To investigate the relationship between full breastfeeding at 3 months postpartum and postnatal depressive symptoms among mothers in Sabah, Malaysia.
    METHODS: A prospective cohort study of 2072 women was conducted in Sabah during 2009-2010. Participants were recruited at 36 to 38 weeks of gestation and followed up at 1 and 3 months postpartum. Depressive symptoms were assessed using the validated Malay version of the Edinburgh Postnatal Depression Scale (EPDS). Repeated-measures analyses of variance was performed to compare the depression scores over time and between subgroups of breastfeeding mothers.
    RESULTS: Approximately 46% of women were fully breastfeeding their infants at 3 months postpartum. These mothers had significantly (P < .001) lower mean EPDS scores at both 1 and 3 months postpartum (mean ± SD, 4.14 ± 4.12 and 4.27 ± 4.12, respectively) than others who did not initiate or maintain full breastfeeding for 3 months (4.94 ± 4.34 and 5.25 ± 4.05, respectively). After controlling for the effects of covariates, the differences in EPDS scores remained statistically significant (P = .001) between the 2 breastfeeding groups.
    CONCLUSION: Full breastfeeding appeared to be negatively associated with postnatal depressive symptoms for mothers residing in Sabah.

    INTRODUCTION: Globally many women suffer from depression during pregnancy. This study investigated the impact of antenatal depressive symptoms on the duration of breastfeeding up to 6 months among women in Sabah, Malaysia.
    SUBJECTS AND METHODS: A prospective cohort study of 2,072 women was conducted in Sabah during 2009-2010. Participants were recruited at 36-38 weeks of gestation and followed up at 1, 3, and 6 months postpartum. Depressive symptoms were assessed using the validated Malay version of the Edinburgh Postnatal Depression Scale (EPDS). Cox regression analyses were performed to determine the relationship between antenatal EPDS scores and cessation of breastfeeding before 6 months postpartum.
    RESULTS: In total, 1,078 (52%) women with complete information on breastfeeding duration were included in the final sample. Approximately 99% of mothers were breastfeeding at discharge, and 87% of them continued to breastfeed at 6 months postpartum. Women with an antenatal EPDS score of 8 or above were twice more likely to stop breastfeeding before 6 months (adjusted hazards ratio=1.95; 95% confidence interval, 1.26, 3.01) than those who scored less than 4 on the EPDS.
    CONCLUSIONS: Depressive symptoms during pregnancy appeared to be associated with early breastfeeding cessation for mothers residing in Sabah.

    BACKGROUND: Breastfeeding and wet nursing have been synonymous since ancient times. The practice of wet nursing of another woman's child in Malaysia is on the rise due to the emergence of awareness among the public about the importance and advantages of breast milk. However, problems arise when there is no systematic system to record and trace the milk mother and milk child data, especially for Muslim participants as milk kinship could affect their relationship status in Islam. Therefore, this study aims to determine the practice of wet nursing among Muslim mothers in Selangor. Simultaneously, this study intends to provide the authorities with an accurate picture of the more aggressive compilation of steps to prevent duplication of consanguinity in wet nursing.

    METHODS: This cross-sectional study was conducted on 100 women who had breastfed another child in Selangor. Data were obtained using a validated questionnaire (Cronbach alpha = 0.8) and processed using the SPSS software.

    RESULTS: Results showed 43.0% of respondents had at least breastfed one someone else's child. Meanwhile, there were 3.0% of the respondents were nursing seven to ten other children. A total of 237 children have been breastfed by the respondents (n = 100). Of these, 21.5% children were breastfed less than five times, while 78.5% children were breastfed less than five times. Most mothers recorded their milk child background data, and this shows that the community is aware of the importance of data documentation and it indirectly proves that the authorities should act on these current needs.

    CONCLUSIONS: This study shows that there is a wet nursing practice in the society. Obviously, a phenomenon, trend and practice in the society has the ground and basis as to why it existed and is upheld. Researches related to wet nursing and matters connected to it should continue so as to bring about much good to society.

    BACKGROUND: The Iowa Infant Feeding Attitude Scale (IIFAS) was developed to measure maternal attitudes toward infant feeding, but a number of validated studies on the IIFAS found that it was subject to methodological limitations.

    OBJECTIVE: The purpose of this study was to evaluate the psychometric properties of the IIFAS among a multiethnic population in Singapore.

    METHODS: A cross-sectional research design was used on a sample of 417 antenatal women. The internal consistency and stability of the IIFAS were evaluated using Cronbach's α and test-retest reliability. Known-group comparisons discriminated certain group differences in a predictable way. A series of exploratory factor analyses (EFAs) was conducted to test the factor structure of the IIFAS using the maximum likelihood and principal axis factoring. The number of factors was selected according to theoretical and statistical considerations. A confirmatory factor analysis (CFA) was further performed to validate the factor structure constructed in the prior EFA.

    RESULTS: The IIFAS had a Cronbach's α and Pearson correlation of 0.79 and 0.85, respectively. The known-group comparisons among certain groups were supported. The EFA results showed that the 3-factor structure produced the most interpretable and theoretical sense. A second-order CFA was conducted to confirm the construct dimensionality of the 15-item IIFAS, with satisfactory fit indices found.

    CONCLUSION: The 15-item IIFAS is a psychometrically sound measurement tool that health care professionals can use to understand the diverse infant feeding attitudes and knowledge among different ethnic groups in order to provide breastfeeding interventions that are culturally sensitive.

    AIMS: To examine the pattern of and the influence of some socio-demographic factors on infant milk feedings, and the protective role of breastfeeding against infections.
    METHODS: Mothers who breastfed their infants (exclusively or partially) at 6 weeks postpartum, and who had singleton pregnancies and healthy infants at birth, were interviewed when their infants had reached 6 months of age.
    RESULTS: Of the 234 mothers studied, only 31 (13%) mothers were practising exclusive breastfeeding (EBF) and 133 (57%) mothers were using exclusive infant formula feeding (EIF). Solid and semi-solid foods were introduced between 4 to 6 months of life in 89% of the infants. On logistic regression analysis, mothers who were in paid employment [OR 0.25, 95% CI 0.15, 0.42] and not breast feeding at 6 weeks [OR 0.32, 95% CI 0.19, 0.54] had decreased odds of EBF. Antenatal plans to breastfeed, breast-feeding difficulties, ethnicity, level of parental education, parental ages, fathers' income, primigravida status and infants' gender were not significant co-variates. In comparison, EIF was more likely in mothers who worked, practised mixed feedings at 6 weeks and of Chinese descent. There were no significant differences in the rates of upper respiratory tract infections (URTI) or diarrhoeal illnesses between the infants who were or were not being breast-fed.
    CONCLUSIONS: Most mothers were unable to breastfeed their infants exclusively in the recommended first 4 to 6 months of life. Complementary changes outside the hospital and maternity services are essential in improving breastfeeding rates. Breastfeeding does not appear to confer significant protection to either URTI or gastrointestinal tract infections.

    BACKGROUND: Biological signaling and communication between mothers and infants during breastfeeding may shape infant behavior and feeding. This signaling is complex and little explored in humans, although it is potentially relevant for initiatives to improve breastfeeding rates.

    OBJECTIVES: The aim of this study was to investigate physiological and psychological aspects of mother-infant signaling during breastfeeding experimentally, testing the effects of a relaxation intervention on maternal psychological state, breast milk intake, milk cortisol levels, and infant behavior and growth.

    METHODS: Primiparous breastfeeding mothers and full-term infants were randomly assigned to receive relaxation therapy [intervention relaxation group; n = 33 (RG)] or to the control group [n = 31 (CG); no relaxation therapy] at 2 wk postpartum. Both groups received standard breastfeeding support. Home visits were conducted at 2 (HV1), 6 (HV2), 12 (HV3) and 14 (HV4) wk to measure maternal stress and anxiety, breast milk intake and milk cortisol, and infant behavior and growth.

    RESULTS: RG mothers had lower stress scores postintervention than the CG (HV3 ∆ = -3.13; 95% CI: -5.9, -0.3) and lower hindmilk cortisol at HV1 (∆ = -44.5%; 95% CI: -76.1%, -12.9%) but not at HV2. RG infants had longer sleep duration (∆ = 82 min/d; 95% CI: 16, 149 min/d) at HV2 and higher gains in weight and body mass index standardized deviation score than the CG infants (∆ = 0.76; 95% CI: 0.3, 1.22; and ∆ = 0.59; 95% CI: 0.09, 1.1, respectively). RG infants had a mean milk intake at HV3 that was 227 g/d higher than that of the CG infants (P = 0.031) after controlling for gender and milk intake at HV1.

    CONCLUSIONS: The trial shows the effectiveness of a simple relaxation intervention for improving maternal and infant outcomes and identifies some potential signaling mechanisms for investigation in future and larger studies, especially in settings where mothers are more stressed, such as those with preterm or low birth weight infants. This trial was registered at clinicaltrials.gov as NCT01971216.
