Breastfeeding prevalence and practices among Singaporean Chinese, Malay and Indian mothers

Clinical significance and main parameters promoting the breast‑feeding strategy (Review)

Breastfeeding provides numerous nutritional and immunological benefits, promotes neurological and cognitive development, and protects against chronic and infectious diseases, rendering it beneficial to the survival and well-being of infants. According to international recommendations, infants should be exclusively breastfed for the first 6 months. However, despite global health recommendations and funding initiatives, exclusive breastfeeding rates remain low worldwide. A number of studies attribute the low rates to factors that can be grouped into demographic, psychosocial, economic and midwifery factors, and outline the profile of each mother who opts to exclusively breastfeed her infant. In addition, the number of previous pregnancies, induced labor, the use of epidurals at birth or the possibility of the newborn being delivered prematurely, and the need for admission to an intensive care unit are the factors that reduce the likelihood of exclusive breastfeeding. Further research is required to understand the factors influencing the initiation and maintenance of exclusive breastfeeding, as international interventions have been ineffective. The aim of the present review was to provide an up-to-date summary of these various factors in an aim to assist health care professionals and policy makers in developing effective interventions with which to promote and support exclusive breastfeeding.

The Effect of a 20-Hour Baby-Friendly Hospital Initiative Training Program on Nurses' Breastfeeding Knowledge, Attitudes and Confidence, in a Tertiary Hospital in Singapore

OBJECTIVE

The Baby-Friendly Hospital Initiative (BFHI) enables maternity units to be centers of breastfeeding support to increase breastfeeding rates. This study evaluates the impact of the 20-hour BFHI training course on nurses' breastfeeding knowledge, attitude, and confidence in breastfeeding practice in a tertiary hospital in Singapore.

STUDY DESIGN

Seventeen sessions of the 20-hour BFHI training course were conducted by lactation consultants from 2010 to 2013 at the National University Hospital, Singapore. An anonymous self-administered survey on knowledge, attitude, and confidence in breastfeeding practices were distributed to nurses before (2009) and after (2014) the training courses to assess effectiveness of training.

RESULTS

One-hundred forty nurses and one hundred forty-eight nurses participated in the surveys in 2009 and 2014, respectively. Majority were registered nurses who worked in the postnatal wards and the neonatal intensive care unit. After training, there were significant improvements for five of eight items in infant feeding knowledge, including greater awareness of the International Code of Marketing of Breastmilk Substitutes and medical contraindication for breastfeeding. Participants reported more confidence in assisting mothers on breastfeeding, 77.1 to 88.5% (p = 0.019); advising hand expressing breast milk, 75.7 to 86.5% (p = 0.012); and advising attachment to the breast, 75.7 to 89.2% (p = 0.004) in 2014 compared with 2009. However, despite having high levels of confidence, only about half the nurses reported being able to assist mothers in breastfeeding, mainly due to time constraints.

CONCLUSION

Implementation of the 20-hour BFHI training program positively influenced nurses' breastfeeding knowledge, attitude, and confidence in breastfeeding practices. Hospital procedures and manpower requirements should be re-examined to overcome nursing constraints in providing breastfeeding help to postpartum mothers.

KEY POINTS

· Nurses have low breastfeeding knowledge pretraining.. · The 20-hour BFHI training course is effective.. · Nurses have inadequate time to support breastfeeding..

Association between breastfeeding and sleep patterns in infants and preschool children

BACKGROUND

Although most studies have reported unfavorable short-term effects of breastfeeding on early-childhood sleep-wake behaviors that potentially attenuate over time, findings have remained inconsistent.

OBJECTIVES

We assessed associations of breastfeeding with longitudinal day-, night-, and total-sleep trajectories and with sleep-wake behaviors in healthy infants and preschoolers.

METHODS

Caregivers of naturally conceived, term, singleton infants (n = 654) completed the Brief Infant Sleep Questionnaire (3, 6, 9, 12, 18, and 24 mo) and/or Children's Sleep Habits Questionnaire (54 mo), and provided information on their infants' breastfeeding status at 3 mo. Trajectory analyses derived 4 day- (n = 243), 3 night- (n = 248), and/or 4 total- (n = 241) sleep trajectories, each differing in length of sleep duration (short/moderate/long) and variability (variable/consistent). Sleep-wake behaviors from 3 to 24 mo (day/night/total-sleep durations and duration/number of night awakenings) were also assessed for associations with breastfeeding.

RESULTS

After adjusting for potential covariates, formula-fed infants, relative to fully breastfed (predominant or exclusive) infants, were significantly less likely to exhibit moderate (OR: 0.28; 95% CI: 0.11, 0.70) and long consistent (OR: 0.18; 95% CI: 0.07, 0.50) night-sleep trajectories and less likely to exhibit moderate (OR: 0.21; 95% CI: 0.07, 0.61) and long consistent (OR: 0.12; 95% CI: 0.04, 0.38) and long variable (OR: 0.16; 95% CI: 0.05, 0.56) total-sleep trajectories, instead of short variable night- and total-sleep trajectories. Partially breastfed infants did not differ from fully breastfed infants for both night- and total-sleep trajectories. No significant differences were found between all groups for day-sleep trajectories. Fully breastfed infants had longer night- (6, 9, 12, and 24 mo) and total- (3 and 12 mo) sleep durations than formula-fed infants, albeit a greater number of night awakenings (from 6 to 12 mo).

CONCLUSIONS

Despite more night awakenings, fully breastfed infants have overall longer night- and total-sleep durations (sleep trajectories) than formula-fed infants.

Determinants of exclusive breastfeeding practice among mothers in Sheka Zone, Southwest Ethiopia: A cross-sectional study

Objectives

The objective of this study was to identify the determinants of exclusive breastfeeding (EBF) practice in Sheka zone, Ethiopia. In addition, the study aims to assess the prevalence of EBF practice in the study area.

Study design

A community-based cross-sectional study design was used.

Methods

A random sample of 630 mothers was selected by stratified cluster sampling using Kebele (an administrative unit) as a cluster. Data were collected using interviewer-administered questionnaires between June and July 2017. Descriptive statistics were used to assess the prevalence of EBF. A multivariable logistic regression model was used to identify determinants of EBF practice.

Results

The prevalence of EBF was 76%. The prevalence of EBF decreases as the age of the infant increases: 95.3% of infants aged 1 month were exclusively breastfed, but only 45.5% of infants aged 6 months were exclusively breastfed. The determinants of EBF practice were age of the child, mother’s educational level, marital status, household income, place of delivery, receiving postnatal care and place of residence. Mothers with a child aged <1 month were 34.9 times more likely to be practicing EBF than mothers with a child aged 5–6 months.

Conclusions

Although the prevalence of EBF was below the World Health Organisation recommended level, the practice of EBF in the study area was good. The prevalence of EBF was shown to decrease as infant age increased. Therefore, we recommend that health workers in health centres and hospitals provide advice about EBF and the duration of EBF during postnatal care visits and infant vaccination appointments.

The determinants of EBF included mother’s education, marital status, income, place of residence, age of child, PNC and place of delivery.

Breastfeeding as a Fundamental Islamic Human Right

The argument inherent in this paper is that the religious beliefs and values system deeply shape Muslims' breastfeeding culture and that mapping the religious ideals of Islam is essential given the potential inroads it offers toward enhanced neonatal, prenatal and pediatric practices, as well as the mitigation of malpractice or cultural inhibitors. This paper discusses the Muslim religious, moral and spiritual understanding of breastfeeding as a basic natural right while exploring the peculiar perspectives of Islamic law and ethics on the matter, in an effort to present a relevant coherent overview. This research shows that for Muslims, breastfeeding is intertwined with Islam's system of beliefs and values and hence continues to play a vital role in improving health education and increasing rates of exclusive breastfeeding. Further empirical studies on Muslims' perception and practices of breastfeeding shall highlight the extent to which Muslims adhere to religious and spiritual teachings, the response to cultural, secular and liberal models of child upbringing, and how a Muslim religious discourse may further support and celebrate human lactation and breastfeeding as a basic right.

Knowledge, attitude, motivation and planning of breastfeeding: a cross-sectional study among Jordanian women

BACKGROUND

In Jordan, the rate of exclusive breastfeeding is declining. The trend variation in breastfeeding practice is determined by different factors including antenatal women's attitude and planning which are affected by their awareness and the support they receive. This study aims to assess knowledge, attitude, support, and planning of breastfeeding among Jordanian women.

METHODS

A face-to-face cross-sectional semi-structured questionnaire survey was conducted among healthy women in the antenatal clinic and postpartum ward at three hospitals in Northern Jordan during the period August 2019 to December 2019. Data were collected about demographic characteristics, women's knowledge and attitude towards breastfeeding, antenatal and postnatal support and counseling, and feeding planning. Customized scales were utilized to assess knowledge and attitude. Factors associated with planning to breastfeed were reported.

RESULTS

660 women completed the survey questionnaire. The majority were 20 to 35 years of age, 10% were primiparous, and 30% were employed. 78% were knowledgeable about breastfeeding benefits and aware of WHO recommendations. 72% had a positive attitude towards breastfeeding. More than half received support from their husbands to breastfeed their infants, while less than 20% received any counseling from their obstetric providers. 97% reported their intention to breastfeed, and more than half indicated their willingness to breastfeed exclusively. With multivariable logistic regression modelling, predictors of EBF planning include: primiparity (AOR 1.79; 95% CI 1.1, 3.25), positive attitude (AOR 1.80; 95% CI 1.05, 3.1) and positive husband's support (AOR 1.92; 95% CI 1.18, 3.15). Barriers include women's employment (AOR 0.43; 95% CI 0.26, 0.70) and low birthweight (AOR 0.46; 95% CI 0.25, 0.84).

CONCLUSION

Jordanian women are highly knowledgeable about breastfeeding benefits, and they exhibit a positive attitude towards breastfeeding resulting in a very high percentage intending to breastfeed their infants. Limited counseling about breastfeeding is a major gap in antenatal care. As intentions might not reflect the actual practice after delivery, gaps and barriers affecting the determinants of successful breastfeeding should be identified, and corrective tools should be implemented accordingly. Allocating a specific time for antenatal or postnatal counseling and support is expected to promote breastfeeding practice in our population.

Predictors of exclusive breastfeeding across three time points in Bangladesh: an examination of the 2007, 2011 and 2014 Demographic and Health Survey

Background

The objective of this study was to explore predictors of exclusive breastfeeding (EBF) in Bangladesh using data from 2007, 2011 and 2014, specifically focusing on potential reasons why rates of EBF changed over those time periods.

Methods

Data on mother/infant pairs with infants <6 months of age were examined at the three time points using the Bangladesh Demographic and Health Survey. The EBF prevalence, changes in EBF since the previous survey and determinants of EBF at each time period were examined using t-tests, χ² and multilevel logistic regression.

Results

The prevalence of EBF was 42.5, 65 and 59.4% in 2007, 2011 and 2014, respectively. The age of the child was significantly associated with EBF across all time points. The largest changes in EBF occurred in the 3- to 5-month age group. Predictors of EBF in this specific age group were similar to overall predictors (e.g. age of the child and region). Participation of the mother in household decisions was a significant predictor in 2014.

Conclusions

EBF prevalence in Bangladesh increased between 2007 and 2011 and then decreased between 2011 and 2014. The increase in 2011 may have been the result of widespread initiatives to promote EBF in that time frame. Due to the unexplained decrease in EBF between 2011 and 2014, there is still a need for interventions such as peer counselling, antenatal education and community awareness to promote EBF.

Stress and anxiety among mothers of premature infants in a Malaysian neonatal intensive care unit

OBJECTIVE

This study aims to determine maternal stress and anxiety as perceived by mothers whose premature infants were admitted to the neonatal intensive care unit (NICU) and to identify maternal stress and its relationship with maternal and infant characteristics and anxiety.

BACKGROUND

Vulnerable premature infants commonly require special care in the NICUs. In most cases, prolonged hospitalization results in stress and anxiety for the mothers.

METHODS

A non-probability convenience survey was used in a public hospital, with 180 mothers completing the 26-item Perceived Stress Scale (PSS) and a 40-item State-Trait Anxiety Inventory (STAI).

RESULTS

56.5% of mothers had high levels of stress, 85.5% of mothers had a high level of state-anxiety and 67.8% of mothers had a high level of trait-anxiety. The stress experienced by these mothers had a significant relationship with anxiety, and was found to be associated with state and trait anxiety levels, but not with maternal and infant characteristics.

CONCLUSION

Mothers in this setting revealed high levels of stress and anxiety during their premature infants' NICU admission. An immediate interventional programme focusing on relieving mothers' anxiety and stress is needed to prevent maternal stress and anxiety at an early stage.

Breastfeeding rates and barriers: a report from the state of Qatar

Objective

The aim of the study was to outline breastfeeding barriers faced by women residing in the State of Qatar.

Methods

A cross-sectional study through a telephone interview was conducted at Hamad Medical Corporation, the only tertiary care and accredited academic institution in the State of Qatar. Mothers of children born between the period of January 1, 2012 and December 31, 2012 in the State of Qatar were contacted.

Results

Of the total 840 mothers who were contacted for the telephone survey, 453 mothers agreed to be interviewed (response rate 53.9%), while 364 (43.3%) did not answer the phone, and 21 (2.5%) answered the phone but refused to participate in the study. The overall breastfeeding initiation rate among the mothers was 96.2%, with 3.8% mothers reporting that they had never breastfed their baby. The percentage of mothers who exclusively breastfed their children in the first 6 months was 24.3%. The most common barriers to breastfeeding as perceived by our participants were the following: perception of lack of sufficient breast milk after delivery (44%), formula is easy to use and more available soon after birth (17.8%), mom had to return to work (16.3%), lack of adequate knowledge about breastfeeding (6.5%), and the concept that the infant did not tolerate breast milk (4.9%).

Conclusion

Exclusive breastfeeding barriers as perceived by women residing in the State of Qatar, a wealthy rapidly developing country, do not differ much from those in other nations. What varies are the tremendous medical resources and the easy and comfortable access to health care in our community. We plan to implement a nationwide campaign to establish a prenatal breastfeeding counseling visit for all expecting mothers.

Early initiation and regular breast milk expression reduces risk of lactogenesis II delay in at-risk Singaporean mothers in a randomised trial

INTRODUCTION

Lactogenesis II (LaII) failure can be prevented in at-risk mothers with simple proactive interventions. In a randomised trial, we investigated the efficacy of early and regular breast milk expression in establishing LaII, using an electric double-breast pump.

METHODS

Mothers with uncomplicated singleton deliveries were randomised to intervention (n = 31) or control (n = 29) groups. The former commenced breast milk expression with an electric pump within one hour of delivery and maintained regular expression with direct breastfeeding. Control mothers directly breastfed without regular pump expression. Expressed milk volumes were analysed for citrate, lactose, sodium and protein.

RESULTS

Median time of LaII was Day 3 (interquartile range [IQR] 1 day) with intervention and on Day 4 (IQR 1 day) among controls (p = 0.03). Biochemical steady-state concentrations were achieved around early Day 4 (sodium, total protein) and Days 4-5 (citrate, lactose). Sodium, protein and lactose levels were similar in both groups over seven days, at 5.80 mM, 0.68 mM and -13.38 mM, respectively. Mean daily milk volume with intervention was 73.9 mL on Day 3 and 225.2 mL on Day 7, greater than controls (25.4 mL on Day 3 and 69.2 mL on Day 7; p < 0.2). Mean infant weights were similar on Day 8 at 3,477 g with intervention and 3,479 g among controls.

CONCLUSION

LaII is established by postnatal Day 3 with early initiation of regular breast milk expression, a useful intervention for mothers at risk of early-onset breastfeeding failure.

Factors associated with breastfeeding intent among mothers of newborn babies in Da Nang, Viet Nam

Background

Breastfeeding is recognized as the single most cost-effective intervention to reduce child morbidity and mortality. However, few studies have explored perceived barriers to breastfeeding and factors associated with breastfeeding intent among mothers of newborn babies in Viet Nam. We conducted a study to assess breastfeeding initiation rates, intent to breastfeed exclusively for 6 months or more and perceived barriers to breastfeed among mothers of newborn babies in Da Nang, Viet Nam.

Methods

We conducted a cross-sectional questionnaire survey of mothers in the postnatal wards of Da Nang Hospital for Women and Children in central Viet Nam from 10 February 2017 to 24 February 2017, following implementation of the World Health Organization (WHO) Essential Newborn Care (ENC) package.

Results

Of 286 mothers surveyed, 259 (90.6%) initiated breastfeeding; 203/258 (78.7%) within 1 hour (h) of birth. Most (207, 72.4%) mothers indicated intent to breastfeed exclusively for 6 months or more, but this was lower among mothers of preterm babies (82.2% versus 20.0%, p < 0.001) and those without post-secondary school education (74.8% versus 55.6%, p = 0.02). Amongst mothers struggling to establish breastfeeding, 18/27 (66.7%) had a Cesarean section. Planned non-exclusive breastfeeding was mostly (39, 60.9%) motivated by mothers’ concern that their milk supply would be insufficient for their baby’s growth requirements. Most mothers had good knowledge about the benefits of breastfeeding and indicated strong decision autonomy.

Conclusions

We documented high rates of early breastfeeding establishment and intent to breastfeed exclusively for 6 months or more. This probably reflects high levels of maternal education and successful implementation of the WHO ENC package. Mothers of premature babies may benefit from additional support.

Paid maternity leave extension and exclusive breastfeeding practice: evidence from Brunei

Background

Exclusive breastfeeding (EBF) of infants in their first 6 months postpartum is beneficial. However, maternal employment and short maternity leave impede EBF practice. In 2011, Brunei implemented a new Maternity Leave Regulation to extend paid maternity leave.

Objectives

To compare the prevalence of EBF between employed and nonworking mothers in Brunei, before and after extending paid maternity leave, to determine its effect on EBF and to determine the effects of maternal and infant sociodemographic characteristics.

Methods

Cross-sectional review of feeding records for infants born in 2010 (n = 6412, 85.5% all live births) and 2013 (n = 6680, 85.7%).

Results

EBF prevalence at 6 months postpartum increased from 29% in 2010 to 41% in 2013. EBF prevalence was higher among multiparous mothers (P < 0.001), mothers of Malay ethnicity (P < 0.05), and mothers of girls (P < 0.01 only in 2013) in both years. EBF prevalence among government-employed mothers (81.0%, 67.7%, and 57.8%) was greater than it was among nonworking mothers (79.1%, 66.3%, and 56.9%) by 1.9, 1.4, and 0.9 percentage points, respectively, during the first 3 months of active paid maternity leave in 2013. Mothers employed in the government and private sectors showed greater increases in the practice of EBF (15.5 and 10.8 percentage points respectively) than nonworking mothers (8.8 percentage points) from 2010 to 2013.

Conclusions

EBF prevalence increased after extending paid maternity leave, with the greatest increases seen among employed mothers. Maternal ethnicity, parity, and the sex of the infant were also correlated with EBF.

Factors affecting breastfeeding adherence among Chinese mothers: A multicenter study

Breastfeeding is beneficial for both infant and mother, but discontinuation of breastfeeding is very common.To investigate maternal breastfeeding intention and the rate of breastfeeding based on the theory of reasoned action, and analyze the predominant factors associated with breastfeeding and breastfeeding problems.This observational study was conducted in 3 hospitals. Three researchers recruited women at 3 time points in the hospitals: initial documentation of pregnancy at the outpatient department, prenatal admission, and postpartum discharge. SPSS version 21 was used for statistical analyses. Significance was set at P < .05. In the multivariate analysis, binary logistic regression was used and odds ratios (ORs) with 95% confidence intervals (CI) were calculated.We recruited 1260 women, with 420 pregnant women at each time point. 55.1% of the infants were exclusively breastfed, 40.6% were mixed fed, and 4.3% were formula fed when discharged from hospital. A total of 53.8% of the mothers declared having breastfeeding problems. The multivariate analysis showed that nonsuccessful breastfeeding was associated with neonatal birth length, food intake before breastfeeding, infrequent sucking, the intention of breastfeeding, understanding level of the benefits of breastfeeding and that breastfeeding problems were related with the understanding level of the benefits of breastfeeding, neonatal birth length, normal vaginal delivery, breast size, the experience of breastfeeding, use of pacifier and the needs of family member's support in breastfeeding.Most mothers who intended to practice exclusive breastfeeding initially chose to add formula and had breastfeeding problems when discharged from hospital. Successful breastfeeding depends on antenatal and postnatal breastfeeding education and on support provided by healthcare professionals.

Application of cabbage leaves compared to gel packs for mothers with breast engorgement: Randomised controlled trial

BACKGROUND

The effects of cold cabbage leaves and cold gel packs on breast engorgement management have been inconclusive. No studies have compared the effects of these methods on breast engorgement using a rigorous design.

OBJECTIVES

To examine the effectiveness of cold cabbage leaves and cold gel packs application on pain, hardness, and temperature due to breast engorgement, the duration of breastfeeding and satisfaction.

DESIGN

A randomised controlled three-group pre-test and repeated post-test study.

SETTING

A private maternal and children's hospital in Singapore.

PARTICIPANTS

Mothers (n=227) with breast engorgement within 14days after delivery.

METHODS

The mothers were randomly assigned into either cold cabbage leaves, cold gel packs, or the control group. Pain, hardness of breasts, and body temperature were measured before treatment. Two sets of post-test assessments were conducted at 30min, 1h, and 2h after the first and second application. The duration of breastfeeding was measured up to 6 months. IBM SPSS 23.0 was used to analyse the data.

RESULTS

Mothers in the cabbage leaves and gel packs groups had significant reductions in pain at all post-intervention time points compared to the control group, starting from 30min after the first application of cabbage leaves (mean difference=-0.38, p=0.016) or gel packs (mean difference=-0.39, p=0.013). When compared to the control group, mothers in the cabbage leaves group had significant reductions in the hardness of breasts at all post-intervention time points, and mothers in the gel packs group had significant reductions in the hardness of breasts at two time points (1h and 2h after the first and second application, respectively). Mothers in the cabbage leaves group had significant reductions in pain (mean difference=-0.53, p=0.005) and hardness of breasts (mean difference=-0.35, p=0.003) at 2h after the second application compared to those in the gel packs group. Both interventions had no impact on body temperature. There was no significant difference in the durations of breastfeeding for mothers among the three groups at 3-month and 6-month follow-up. More mothers were very satisfied/satisfied with the breast engorgement care provided in the cabbage leaves group compared to the other groups.

CONCLUSION

While cold cabbage leaves and cold gel packs can relieve pain and hardness in breast engorgement, the former had better effect, which can be recommended to postnatal mothers to manage breast engorgement.

The decision of breastfeeding practices among parents attending primary health care facilities in suburban Malaysia

Objectives

This study aimed to determine the association between decision making for breastfeeding practices and associated factors for exclusive breastfeeding practices among parents attending primary health care facilities.

Methods

This cross-sectional study involved 196 parents who attended primary health care facilities in suburban Malaysia. A self-administered questionnaire was given to assess decision-making styles and factors associated with exclusive breastfeeding practices. Systematic random sampling was used for the non-exclusive breastfeeding group, and convenience sampling was used for the exclusive breastfeeding group. Multiple logistic regression analysis was conducted to determine the associated factors for exclusive breastfeeding practices.

Results

We found an association between the mutual decision of parents on exclusive breastfeeding and exclusive breastfeeding practices. Previous exclusive breastfeeding experience, fathers' ages, mothers' occupations and mutual decisions had significant impact on exclusive breastfeeding practices.

Conclusion

The important determinant for practising exclusive breastfeeding is parents' mutual decisions. Therefore, practitioners need to continuously educate and emphasize the fathers' role in the breastfeeding process.

Infant Feeding Practices in a Multi-Ethnic Asian Cohort: The GUSTO Study

The optimal introduction of complementary foods provides infants with nutritionally balanced diets and establishes healthy eating habits. The documentation of infant feeding practices in multi-ethnic Asian populations is limited. In a Singapore cohort study (GUSTO), 842 mother-infant dyads were interviewed regarding their feeding practices when the infants were aged 9 and 12 months. In the first year, 20.5% of infants were given dietary supplements, while 5.7% took probiotics and 15.7% homeopathic preparations. At age 9 months, 45.8% of infants had seasonings added to their foods, increasing to 56.3% at 12 months. At age 12 months, 32.7% of infants were given blended food, although 92.3% had begun some form of self-feeding. Additionally, 87.4% of infants were fed milk via a bottle, while a third of them had food items added into their bottles. At both time points, more than a third of infants were provided sweetened drinks via the bottle. Infants of Indian ethnicity were more likely to be given dietary supplements, have oil and seasonings added to their foods and consumed sweetened drinks from the bottle (p < 0.001). These findings provide a better understanding of variations in infant feeding practices, so that healthcare professionals can offer more targeted and culturally-appropriate advice.

Determinants of Breastfeeding Practices and Success in a Multi-Ethnic Asian Population

BACKGROUND

Many countries in Asia report low breastfeeding rates and the risk factors for early weaning are not well studied. We assessed the prevalence, duration, and mode of breastfeeding (direct or expressed) among mothers of three Asian ethnic groups.

METHODS

Participants were 1,030 Singaporean women recruited during early pregnancy. Data collected included early breastfeeding experiences, breastfeeding duration, and mode of breastfeeding. Full breastfeeding was defined as the intake of breast milk, with or without water. Cox regression models were used to identify factors associated with discontinuation of any and full breastfeeding. Logistic regression analyses assessed the association of ethnicity with mode of breastfeeding.

RESULTS

At 6 months postpartum, the prevalence of any breastfeeding was 46 percent for Chinese mothers, 22 percent for Malay mothers, and 41 percent for Indian mothers; prevalence of full breastfeeding was 11, 2, and 5 percent, respectively. More Chinese mothers fed their infants expressed breast milk, instead of directly breastfeeding them, compared with the other two ethnic groups. Duration of any and full breastfeeding were positively associated with breastfeeding a few hours after birth, higher maternal age and education, and negatively associated with irregular breastfeeding frequency and being shown how to breastfeed. Adjusting for maternal education, breastfeeding duration was similar in the three ethnic groups, but ethnicity remained a significant predictor of mode of breastfeeding.

CONCLUSIONS

The low rates and duration of breastfeeding in this population may be improved with breastfeeding education and support, especially in mothers with lower education. Further work is needed to understand the cultural differences in mode of feeding and its implications for maternal and infant health.

South Vietnamese Rural Mothers' Knowledge, Attitude, and Practice in Child Health Care

A study of 600 rural under-five mothers' knowledge, attitude, and practice (KAP) in child care was performed in 4 southern provinces of Vietnam. The mothers were randomly selected and interviewed about sociodemographic factors, health seeking behaviour, and practice of home care of children and neonates. 93.2% of the mothers were literate and well-educated, which has been shown to be important for child health care. 98.5% were married suggesting a stable family, which is also of importance for child health. Only 17.3% had more than 2 children in their family. The mother was the main caretaker in 77.7% of the families. Only 1% would use quacks as their first health contact, but 25.2% would use a private clinic, which therefore eases the burden on the government system. Nearly 69% had given birth in a hospital, 27% in a commune health station, and only 2.7% at home without qualified assistance. 89% were giving exclusive breast feeding at 6 months, much more frequent than in the cities. The majority of the mothers could follow IMCI guideline for home care, although 25.2% did not deal correctly with cough and 38.7% did not deal correctly with diarrhoea. Standard information about Integrated Management of Childhood Illnesses (IMCI) based home care is still needed.

Predictors of breastfeeding initiation in Hong Kong and Mainland China born mothers

Background

In recent years there has been a steady influx of immigrants into Hong Kong from Mainland China, where breastfeeding patterns differ. Studies in other regions have found substantial differences in breastfeeding rates between native-born and immigrant mothers. The purpose of this study was to examine factors associated with breastfeeding initiation in Hong Kong born and Mainland China born mothers living in Hong Kong.

Methods

We used a multi-center cross-sectional study design and recruited 2761 new mothers from the postnatal wards of all eight public hospitals in Hong Kong that offer obstetric services. We assessed breastfeeding status as well as various socio-demographic, maternal and birth characteristics. Chi-square tests and multivariable logistic regression were used to identify the predictors of breastfeeding initiation in Hong Kong born and Mainland China born participants.

Results

80.3 % of Hong Kong and 81.1 % of Mainland Chinese born women initiated breastfeeding. In the fully adjusted models, multiparity (Odds Ratio [OR] 0.53, 95 % CI 0.43–0.66) and maternal smoking (OR 0.29, 95 % CI 0.18–0.45) were strongly associated with failure to initiate breastfeeding in both Hong Kong and Mainland China born participants. In Hong Kong born mothers, participants with lower maternal education and those who had a cesarean section were significantly less likely to breastfeed. For Mainland China born mothers, paternal smoking (OR 0.70, 95 % CI 0.49–0.99) and having a pregnancy-related health problem (OR 0.60, 95 % CI 0.38–0.94) were both additional risk factors for not breastfeeding.

Conclusion

This study has identified predictors of breastfeeding initiation in Hong Kong and Mainland China born mothers. Given the current high breastfeeding initiation rates among both groups, antenatal breastfeeding education and promotion programmes need to specifically intervene with sub-groups of pregnant women at risk for not breastfeeding so that their efforts are more strategic and cost-effective.

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.

[Weaning before the age of 6 months in Marrakech: associated factors and prevalence]

BACKGROUND

In Morocco breastfeeding has become a declining practice. The objectives of this study were to estimate the prevalence of weaning before the age of 6 months and to identify associated factors.

METHODS

A cross-sectional survey was conducted among 400 mothers of infants aged 0 to 24 months. Participants were recruited from patients attending 40 randomly selected general practices in Marrakech. A trained interviewer administered a questionnaire to collect data on breastfeeding practice and factors associated with it. Early weaning was defined as a cessation of breastfeeding before the age of 6 months and was studied in mother-child couples whose infants were aged 6 months and older. Three binary logistic regression models were used to model the probability that an infant aged 6 months or more is weaned early.

RESULTS

Breastfeeding was initiated by the majority of respondents (97.5%). Early weaning was observed in 75 infants (28% of registered weaning). Factors associated with early weaning were: mother having an occupational activity (Odds Ratio [OR]=2.09; 95% confidence interval [CI]: [1.07-4.06]), caesarean delivery (OR=4.15; 95% CI: [1.74-9.88]) and the fact that the pregnancy was desired (OR=0.19; 95% CI: [0.05-0.68]).

CONCLUSION

Weaning before 6 months of age is a common practice in our context. Identifying factors associated with early weaning is critical to promote breastfeeding.

Outcome of non-protractile nipple correction with breast cups in pregnant women: a randomized controlled trial

OBJECTIVE

The benefit of antenatal nipple correction remains inconclusive. This study aims to demonstrate the value of breast cups in lengthening of short nipples and to compare the breastfeeding rate between the users and the nonusers.

SUBJECTS AND METHODS

Singleton pregnant women with at least one short nipple (<7.0 mm) were enrolled at a gestational age (GA) of 16-20 weeks. All participants were randomly allocated into the breast cup group (BC group) and the expectant group (EX group). The first group was requested to wear breast cups for at least 8 hours during the daytime, whereas the second group was not. The nipple length was evaluated prior to the study and at every visit until GA of 36 weeks by the same blinded evaluator.

RESULTS

Among 90 eligible participants (43 in the BC group, 47 in the EX group), the nipple elongation in the BC group was significantly higher than in the EX group (2.37±1.29 mm versus 1.84±0.98 mm; p=0.032), with a mean difference of 0.53±0.24 mm (95% confidence interval 0.05, 1.01). On Day 3, there was an insignificantly higher number of mothers with a LATCH score of ≥7 in the BC group. The 3-month exclusive breastfeeding rate in the BC group was insignificantly greater than that of the EX group (65.39% versus 50.0%; p=0.35).

CONCLUSIONS

Breast cups are safe and well tolerated by users and evidently increase the length of short nipples and enhance the exclusive breastfeeding rate.

Factors affecting exclusive breast-feeding during the first 6 months in Korea

BACKGROUND

The aim of this study was to identify the status of exclusive breast-feeding (EBF) in Korea and analyze the factors affecting exclusive breast-feeding at 6 months of age.

METHOD

This study was based on data obtained from the Korea National Health and Nutrition Examination Survey (KNHANES) IV, conducted from January 2007 to December 2008. A total of 404 mother-infant pairs were recruited. Exclusive breast-feeding was defined according to the criteria established by the World Health Organization.

RESULT

The rate of EBF was 60.9% for 1 month, 55.0% for 3 months, 35.4% for 6 months, 3.7% for 9 months and 1.2% for 12 months after birth. According to a stepwise logistic regression analysis, factors that were positively associated with EBF at 6 months were younger maternal age (odds ratio [OR] = 0.85, 95% confidence interval [CI]: 0.79-0.92), higher maternal education level (OR = 2.29, 95%CI: 1.17-4.46) and living in a capital city (OR = 2.64, 95%CI: 1.46-4.75).

CONCLUSION

The rate of EBF in Korea is still suboptimal. To promote EBF, persistent and systematic education and campaigns for breast-feeding should be provided, particularly in vulnerable regions.

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.

Impact of baby-friendly hospital practices on breastfeeding in Hong Kong

BACKGROUND

The World Health Organization (WHO) developed the Baby-Friendly Hospital Initiative to improve hospital maternity care practices that support breastfeeding. In Hong Kong, although no hospitals have yet received the Baby-Friendly status, efforts have been made to improve breastfeeding support. The aim of this study was to examine the impact of Baby-Friendly hospital practices on breastfeeding duration.

METHODS

A sample of 1,242 breastfeeding mother-infant pairs was recruited from four public hospitals in Hong Kong and followed up prospectively for up to 12 months. The primary outcome variable was defined as breastfeeding for 8 weeks or less. Predictor variables included six Baby-Friendly practices: breastfeeding initiation within 1 hour of birth, exclusive breastfeeding while in hospital, rooming-in, breastfeeding on demand, no pacifiers or artificial nipples, and information on breastfeeding support groups provided on discharge.

RESULTS

Only 46.6 percent of women breastfed for more than 8 weeks, and only 4.8 percent of mothers experienced all six Baby-Friendly practices. After controlling for all other Baby-Friendly practices and possible confounding variables, exclusive breastfeeding while in hospital was protective against early breastfeeding cessation (OR: 0.61; 95% CI: 0.42-0.88). Compared with mothers who experienced all six Baby-Friendly practices, those who experienced one or fewer Baby-Friendly practices were almost three times more likely to discontinue breastfeeding (OR: 3.13; 95% CI: 1.41-6.95).

CONCLUSIONS

Greater exposure to Baby-Friendly practices would substantially increase new mothers' chances of breastfeeding beyond 8 weeks postpartum. To further improve maternity care practices in hospitals, institutional and administrative support are required to ensure all mothers receive adequate breastfeeding support in accordance with WHO guidelines.

Work related determinants of breastfeeding discontinuation among employed mothers in Malaysia

Background

This cross-sectional study assesses factors that contribute to discontinuing breastfeeding among employed mothers in Malaysia.

Methods

A structured questionnaire was used in conducting this study involving all government health clinics in Petaling district between July and September 2006. Respondents were Malaysian women with children between the ages of six to twelve months who were formally employed. Factors studied were selected socio-demographic and work-related characteristics.

Results

From a total of 290 respondents, 51% discontinued breastfeeding. The majority (54%) of mothers who discontinued breastfeeding had breastfed their babies for less than three months. Compared to Malay mothers, the risk of breastfeeding discontinuation were higher among Chinese (AOR 3.7, 95% CI: 1.7, 7.8) and Indian mothers (AOR 7.3, 95% CI 1.9, 27.4). Not having adequate breastfeeding facilities at the workplace was also a risk factor for breastfeeding discontinuation (AOR 1.8, 95% CI: 1.05, 3.1).

Conclusion

It is important that workplaces provide adequate breastfeeding facilities such as a room in which to express breast milk and a refrigerator, and allow mothers flexible time to express breast milk.

Predictors of exclusive breast-feeding in early infancy: a survey report from Phnom Penh, Cambodia

BACKGROUND

Exclusive breast-feeding (EBF) is recommended in the first 6 months of an infant's life. This study aims to investigate the present status of infant feeding practices and identify factors that affect EBF practices during the first 6 months following infant birth in Phnom Penh, Cambodia.

METHODS

A cross-sectional survey with a semistructured questionnaire was given to 312 mothers with children aged 6 to 24 months who visited the immunization clinic in the National Maternal and Child Health Centre in Phnom Penh, Cambodia, from December 2005 to February 2006.

RESULTS

Eighty-three percent of mothers fed breast milk exclusively in the first month, whereas only 51.3% continued EBF in the first 6 months. Within 30 minutes after delivery, 39% of mothers began breast-feeding. Results from logistic regression analysis indicate that the lack of a maternal antenatal EBF plan (odds ratio [OR] = 10.01, 95% confidence interval [CI] = 3.68-27.24, p < .001), working mothers (OR = 4.71, 95% CI = 2.77-8.01, p < .001), and lack of paternal attendance at breast-feeding classes (OR = 1.93, 95% CI = 1.13-3.28, p < .05) have independently positive associations with cessation of EBF during the first 6 months of infant life.

CONCLUSION

The findings have helped to identify some important factors affecting EBF practices in the study area in Cambodia. The findings revealed that it is important to educate pregnant mothers, probably through exposure to trained midwives and media, so they may recognize the significance of EBF and will develop intention and plan to feed their babies, keeping in mind the benefits it may yield. Paternal involvement in breast-feeding classes may increase their awareness and consequently complement EBF practices. Finally, development of conducive working environments and policies for working mothers should be carefully explored because it could have positive influence in better care and promotion of EBF.

Breastfeeding and weaning practices among Hong Kong mothers: a prospective study

Background

Breastfeeding provides optimal and complete nutrition for newborn babies. Although new mothers in Hong Kong are increasingly choosing to breastfeed their babies, rates of exclusive breastfeeding are low and duration remains short. The purpose of this study was to describe the breastfeeding and weaning practices of Hong Kong mothers over the infant's first year of life to determine the factors associated with early cessation.

Methods

A cohort of 1417 mother-infant pairs was recruited from the obstetric units of four public hospitals in Hong Kong in the immediate post-partum period and followed prospectively for 12 months or until weaned. We used descriptive statistics to describe breastfeeding and weaning practices and multiple logistic regression to investigate the relationship between maternal characteristics and breastfeeding cessation.

Results

At 1 month, 3 months, 6 months and 12 months only 63%, 37.3%, 26.9%, and 12.5% of the infants respectively, were still receiving any breast milk; approximately one-half of breastfeeding mothers were exclusively breastfeeding. Younger mothers, those with a longer duration of residence in Hong Kong, and those returning to work postpartum were more likely to wean before 1 month. Mothers with higher education, previous breastfeeding experience, who were breastfed themselves and those who were planning to exclusively breastfeed and whose husbands preferred breastfeeding were more likely to continue breastfeeding beyond 1 month. The introduction of infant formula before 1 month and returning to work postpartum were predictive of weaning before 3 months.

Conclusions

Breastfeeding promotion programs have been successful in achieving high rates of breastfeeding initiation but the focus must now shift to helping new mothers exclusively breastfeed and sustain breastfeeding for longer.

Emerging Trends in Breastfeeding Practices in Singaporean Chinese Women: Findings from a Population-based Study

Introduction: This study records the prevalence and patterns of breastfeeding in Singaporean Chinese mothers who gave birth between 2000 and 2008. Materials and Methods: The Strabismus, Amblyopia and Refractive Error in Singaporean Children (STARS) study is a population-based survey conducted in South-Western Singapore. Disproportionate random sampling by 6-month age groups of Chinese children born from 2000 to 2008 was performed. The mothers (n = 3009) completed a standard questionnaire which recorded the initiation, content, method and duration of breastfeeding. World Health Organization (WHO) definitions for feeding content were used: Replacement (exclusive commercial formula or any liquid or solid/semi-solid food, excluding breast milk), Complementary (breast milk, solid/semi-solid foods, and any non-human liquid), and Exclusive (breast milk only, without additional food, drink or water). STARS-specific definitions for feeding method were used: Expressed (breast milk only fed via bottle, with no additional food or non-human liquid), Combination (breast milk and non-breast milk, fed via bottle and breast), and Direct (breast milk only fed via breast). Results: Breastfeeding initiation (overall prevalence 77.0%) and duration increased over time, and were independently associated with higher maternal education: in 2000 and 2001, 68.6% of mothers initiated breastfeeding and 12.9% breast fed for ≤6 months, versus 82.0% and 26.7%, respectively, from 2006 to 2008; 47.4% of primary-school-educated women initiated breastfeeding, and 11.1% fed for ≥6 months, vs 90.9% and 35.3%, respectively, of university-educated women (P <0.001). Expressed, Com bination and Complementary feeding also increased, while Replacement feeding decreased (P<0.001). There was no difference in breastfeeding patterns by the child’s gender. Conclusions: In a population-based sample of Singaporean Chinese mothers giving birth from 2000 to 2008, breastfeeding initiation and duration increased over time and were independently associated with higher maternal education. This increase was associated with increased milk expression and complementary feeding. Thus awareness of breastfeeding benefits is rising in Singapore, but future health policies may need to target less-educated mothers.

Breast-feeding and overweight in Singapore school children

BACKGROUND

Studies from developed Western countries have shown inconsistent associations between breast-feeding and overweight/obesity in children and adolescents. Few data are available from Asian populations. The purpose of the present study was therefore to evaluate the association between breast-feeding and overweight/obesity in a study of 10-12-year-old children in Singapore.

METHODS

A total of 797 school children (49% girls, 76% Chinese) who participated in the Singapore Cohort Study of the Risk Factors for Myopia (SCORM) were examined. Overweight/obesity (n = 179) was defined as age-sex-specific body mass index (BMI) cut-offs corresponding to BMI of 25 kg/m(2) for overweight and 30 kg/m(2) for obesity at age 18 based on the International Obesity Task Force (IOTF) reference.

RESULTS

The prevalence of overweight/obesity was 22.5%. Overall, breast-feeding was not found to be associated with overweight/obesity. After adjusting for potential confounders, the multivariable odds ratio (95% confidence interval) of overweight/obesity was 1.14 (0.80-1.63) for ever breast-fed compared with never breast-fed, 1.00 (0.57-1.72) for breast-fed for >3 months compared to < or =3 months and 0.79 (0.47-1.34) for exclusive/mostly breast-fed compared to partly breast-fed.

CONCLUSIONS

No significant associations were detected among breast-feeding, its type, and duration with overweight/obesity in this Asian cohort of 10-12-year-old children.

Differential Risk for Early Breastfeeding Jaundice in a Multi-ethnic Asian Cohort

Introduction: To explore the relationship between ethnic origin and mode of feeding with early neonatal jaundice, we examined maternal and neonatal risk factors for hyperbilirubinaemia in a multi-ethnic Asian cohort of healthy term newborns. Materials and Methods: This is an observational cohort study in a maternity ward serving a multi-ethnic cosmopolitan community. The relationship between hyperbilirubinaemia (bilirubin 150 mmol/L before 48 hours to 72 hours after birth), ethnic origin, weight loss after birth, need for phototherapy, and other factors were examined. Bivariate comparisons and binary logistic regression were used to investigate the relationship between hyperbilirubinaemia/phototherapy with maternal and neonatal risk factors. Results: A consecutive group of 1034 neonates (56% Chinese, 24% Indian subcontinent, 9% Malay) with birth weights 2500 g was investigated. Overall factors that contributed signifi- cantly to hyperbilirubinaemia/phototherapy were gestational age, Chinese ethnic origin, weight loss of 7%, vaginal delivery, glucose-6-phosphate-dehydrogenase (G6PD) deficiency, breastfeeding and ABO incompatibility. Chinese neonates who were totally breastfed had a higher risk for jaundice [adjusted odds ratio (OR) = 1.64; 95% confidence intervals (CI), 1.11- 2.44; P <0.014], and phototherapy (adjusted OR = 2.75; 95% CI 1.77-4.27; P <0.001) compared to those supplemented with, or totally formula fed. In contrast, the risk of jaundice for non- Chinese infants did not differ according to the mode of feed. Although weight loss as a whole increased the risk for jaundice (adjusted OR = 1.43; 95%CI, 1.03-1.99; P = 0.031), jaundice in Chinese neonates was not due to ineffective breastfeeding because both Chinese and non-Chinese breastfed infants lost similar weights. Conclusions: Chinese ethnic origin was an independent risk factor for hyperbilirubinaemia and phototherapy. Breastfeeding was not a risk factor for hyperbilirubinaemia/phototherapy in non-Chinese Asian infants. Key words: Breastfeeding, Ethnicity, Neonatal jaundice, Phototherapy

Probiotic supplementation in the first 6 months of life in at risk Asian infants--effects on eczema and atopic sensitization at the age of 1 year

BACKGROUND

The role of probiotics in allergy prevention remains uncertain but has been shown in some studies to have a possible protective effect on eczema.

OBJECTIVE

We aimed to assess the effect of probiotic supplementation in the first 6 months of life on eczema and allergic sensitization at 1 year of age in Asian infants at risk of allergic disease.

METHODS

A double-blind, placebo-controlled randomized clinical trial involving 253 infants with a family history of allergic disease was carried out. Infants received at least 60 mL of commercially available cow's milk formula with or without probiotic supplementation [Bifidobacterium longum (BL999) 1 x 10(7) colony forming unit (CFU)/g and Lactobacillus rhamnosus (LPR) 2 x 10(7) CFU/g] daily for the first 6 months. Clinical evaluation was performed at 1, 3, 6 and 12 months of age, with serum total IgE measurement and skin prick tests conducted at the 12-month visit. The primary and secondary end-points were eczema and allergen sensitization, respectively.

RESULTS

The incidence of eczema in the probiotic (22%) group was similar to that in the placebo group (25%) (P=0.53). The median Scoring Atopic Dermatitis score at 12 months was 17.10 (9.74) in the probiotic group and 11.60 (8.40) in the placebo group (P=0.17). The prevalence of allergen sensitization showed no difference (probiotic=24% vs. placebo=19%, P=0.26). The total IgE geometric mean (95% confidence interval) was 18.76 (12.54-24.98) kU/L in the probiotic group and 23.13 (16.01-30.24) kU/L in the placebo group (P=0.15). Atopic eczema (with sensitization) in the probiotic (7.3%) group was comparable to the placebo group (5.8%) (P=0.86).

CONCLUSION

Early life administration of a cow's milk formula supplemented with probiotics showed no effect on prevention of eczema or allergen sensitization in the first year of life in Asian infants at risk of allergic disease. Further work is needed to determine whether timing of supplementation, dose and probiotic strain are important considerations.

Multiparity and the risk of premenopausal breast cancer: different effects across ethnic groups in Singapore

BACKGROUND

The relationship between multiparity and premenopausal breast cancer risk is different in Caucasian, African-American and Hispanic women. For Asian women, this relationship has never been well studied.

METHODS

Within the Singapore Birth Registry, we selected all women who had a first child between 1986 and 2002 (169,936 Chinese, 40,521 Malay, 17,966 Indian). We linked them to the Singapore Cancer Registry data to identify those who developed breast cancer after childbirth (n = 527). We used multivariate Cox analysis to examine the relationship between parity, ethnicity and premenopausal breast cancer risk.

RESULTS

Compared to Chinese, Malay women had increased and Indian women had decreased risks of premenopausal breast cancer (adjusted Hazard Ratios [HRadj] 1.25 [1.0-1.6] and 0.48 [0.3-0.8] respectively). Multiparity did not modify the risk of premenopausal breast cancer in Chinese and Indians. In Malays there was a significant risk reduction with increasing parity (P (trend )0.037). Malay women with one, two and >or=3 children had premenopausal breast cancer risks (HR(adj)) of 1.86 (1.2-3.0), 1.52 (1.1-2.2) and 0.87 (0.6-1.3) respectively compared to their Chinese counterparts.

CONCLUSIONS

The impact of multiparity on premenopausal breast cancer risk differs across ethnic groups in Singapore. Increasing parity reduces the risk of premenopausal breast cancer in Malay, but not in Chinese and Indian women. Uniparous Malay women have twice the risk of premenopausal breast cancer compared to uniparous Chinese. This excess risk disappears after giving birth to >or=3 children. Indian women have lower premenopausal breast cancer risks than Chinese, regardless of their parity status.

Breast-feeding in South Korea: factors influencing its initiation and duration

Objective

To investigate factors influencing the practices of partial breast-feeding (PBF) and exclusive breast-feeding (EBF).

Design

A national, cross-sectional survey was conducted among married women aged 15–49 years from May to August 2003.

Setting

South Korea.

Subjects

A total of 865 mothers answered questions regarding the feeding practices of their youngest baby, born between January 2001 and May 2003.

Results

The initiation rates of PBF and EBF were 81% and 63%, respectively. However, the median durations of PBF and EBF were very short: 12 and 8 weeks, respectively. According to stepwise logistic and Cox regression analyses, the more prenatal care women received, the more likely they were to initiate PBF and EBF but the less likely to continue EBF. Delivery by Caesarean section decreased the initiation of PBF and EBF. The mother’s education level and employment status before marriage, the amount of prenatal care, delivery method and baby’s status at birth affected breast-feeding initiation, whereas the amount of prenatal care influenced breast-feeding duration.

Conclusion

To promote breast-feeding, education and campaigning on the importance of continued breast-feeding should be provided to the general public, particularly to health workers in maternity units.

Antenatal education and postnatal support strategies for improving rates of exclusive breast feeding: randomised controlled trial

OBJECTIVE

To investigate whether antenatal breast feeding education alone or postnatal lactation support alone improves rates of exclusive breast feeding compared with routine hospital care.

DESIGN

Randomised controlled trial.

SETTING

A tertiary hospital in Singapore.

PARTICIPANTS

450 women with uncomplicated pregnancies.

MAIN OUTCOME MEASURES

Primary outcomes were rates of exclusive breast feeding at discharge from hospital and two weeks, six weeks, three months, and six months after delivery. Secondary outcomes were rates of any breast feeding.

RESULTS

Compared with women who received routine care, women in the postnatal support group were more likely to breastfeed exclusively at two weeks (relative risk 1.82, 95% confidence interval 1.14 to 2.90), six weeks (1.85, 1.11 to 3.09), three months (1.87, 1.03 to 3.41), and six months (2.12, 1.03 to 4.37) postnatally. Women receiving antenatal education were more likely to breast feed exclusively at six weeks (1.73, 1.04 to 2.90), three months (1.92, 1.07 to 3.48), and six months (2.16, 1.05 to 4.43) postnatally. The numbers needed to treat to achieve one woman exclusively breast feeding at six months were 11 (6 to 80) for postnatal support and 10 (6 to 60) for antenatal education. Women who received postnatal support were more likely to exclusively or predominantly breast feed two weeks after delivery compared with women who received antenatal education (1.53, 1.01 to 2.31). The rate of any breastfeeding six weeks after delivery was also higher in the postnatal support group compared with women who received routine care (1.16, 1.02 to 1.31).

CONCLUSIONS

Antenatal breast feeding education and postnatal lactation support, as single interventions based in hospital both significantly improve rates of exclusive breast feeding up to six months after delivery. Postnatal support was marginally more effective than antenatal education.
