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

The Phenomenon of Human Migration on the Breastfeeding Practices of Migrant Women: A Scoping Review

Human migrations and different migratory flows have been as old as the practice of breastfeeding (BF). The reasons for migrating, the conditions, and its protagonists are so diverse, often constituting situations of vulnerability and risk for health decision-making at both the individual and collective levels. The relationship between BF and human migration is totally dynamic and includes multiple factors, which is why there is a need to characterize territorially its prevalence rate and variability depending on the context. The migration profiles that can be configured from factors, such as schooling, employment, the host country's health system, and support networks, among others, have heterogeneity between countries that make it necessary to identify them. This study is an in-depth review of the report on the practice of BF in migrant women. The Arksey and O'Malley method was used to perform the PubMed and SciELO searches. The search terms were "exclusive breastfeeding (EBF)," "breastfeeding," "migrant women," and "human migration," and original articles published in English, Spanish, and Portuguese were included. Of the 43 selected articles, differences were found between the various migrant groups, in variables such as socioeconomic level, education, access to health services, maternal knowledge, father factor, culture, and intention to breastfeed. The heterogeneity of the practice of BF between countries, as well as in intraregional migratory flows, establishes different protective or risk factors depending on where the phenomenon develops and its conditions.

Factors Associated with Breastfeeding Initiation and Duration in Greece: Data from the Hellenic National Nutrition and Health Survey

Despite its well-documented benefits, breastfeeding rates and duration worldwide do not meet the recommended goals set by the World Health Organization. Data on infant feeding, socio-demographic, lifestyle and perinatal factors were used from 490 mothers (and 958 children), participants at the Hellenic National Nutrition and Health Survey between 2013−2015. Clustered multiple logistic regression and multilevel mixed-model regression analyses were performed to identify factors associated with breastfeeding initiation and duration, respectively. Maternal lower education [Odds Ratio (OR): 2.29, 95% Confidence intervals (95% CI): 1.30−4.04; p = 0.004], smoking during pregnancy (OR: 3.08, 95% CI: 1.64−5.77; p < 0.001), caesarean section (OR = 3.26, 95% CI: 1.83−5.83; p < 0.001), prematurity (OR = 2.74, 95% CI: 1.40−5.37; p = 0.003) and higher birth order (OR = 1.30, 95% CI: 1.04−1.62; p = 0.020) were associated with increased odds of not initiating breastfeeding. Living in rural areas [beta coefficient b = −27.93, p = 0.043], smoking during pregnancy (b = −64.47, p < 0.001), caesarean section (b = −28.76, p = 0.046) and prematurity (b = −46.67, p = 0.048) were significantly associated with shorter breastfeeding duration. Children born chronologically closer to the survey were more likely to breastfeed and for longer periods. Educational promotion and enhancement of breastfeeding awareness that account for maternal exposures are required. Prevention of prematurity and avoidance of unnecessary caesarean section is crucial, while additional breastfeeding support is needed when preterm birth occurs, or caesarean section cannot be avoided.

Factors associated with breast-feeding initiation and continuation in Canadian-born and non-Canadian-born women: a multi-centre study

OBJECTIVE

To identify factors associated with breast-feeding initiation and continuation in Canadian-born and non-Canadian-born women.

DESIGN

Prospective cohort of mothers and infants born from 2008 to 2012: the Canadian Healthy Infant Longitudinal Development (CHILD) Cohort Study.

SETTING

General community setting in four Canadian provinces.

PARTICIPANTS

In total, 3455 pregnant women from Vancouver, Edmonton, Winnipeg and Toronto between 2008 and 2012.

RESULTS

Of 3010 participants included in the current study, the majority were Canadian-born (75·5 %). Breast-feeding initiation rates were high in both non-Canadian-born (95·5 %) and Canadian-born participants (92·7 %). The median breast-feeding duration was 10 months in Canadian-born participants and 11 months in non-Canadian-born participants. Among Canadian-born participants, factors associated with breast-feeding initiation and continuation were older maternal age, higher maternal education, living with their partner and recruitment site. Rooming-in during the hospital stay was also associated with higher rates of breast-feeding initiation, but not continuation at 6-month postpartum. Factors associated with non-initiation of breast-feeding and cessation at 6-month postpartum were maternal smoking, living with a current smoker, caesarean birth and early-term birth. Among non-Canadian-born participants, maternal smoking during pregnancy was associated with lower odds of breast-feeding initiation and lower odds of breast-feeding continuation at 6 months, and older maternal age and recruitment site were associated with breast-feeding continuation at 6 months.

CONCLUSIONS

Although Canadian-born and non-Canadian-born women in the CHILD cohort have similar breast-feeding initiation rates, breast-feeding initiation and continuation are more strongly associated with socio-demographic characteristics in Canadian-born participants. Recruitment site was strongly associated with breast-feeding continuation in both groups and may indicate geographic disparities in breast-feeding rates nationally.

The Effect of Maternal Self-Regulated Motivation on Breastfeeding Continuation

OBJECTIVE

Women frequently report breastfeeding problems in the early postpartum period. Women who have self-endorsed beliefs that breastfeeding benefits their babies and themselves are more likely to continue breastfeeding despite breastfeeding barriers. Maternal self-endorsed beliefs is a key component of maternal self-regulated motivation. The present study examined the association between maternal self-regulated motivation, breastfeeding duration and exclusivity in Chinese women.

METHODS

This was a prospective cohort study, of which we recruited participants in postnatal maternity units of publicly funded hospitals in Hong Kong. Postpartum women were asked to fill in the validated breastfeeding self-regulation questionnaire (BSRQ) before hospital discharge and their breastfeeding status was assessed by telephone follow-ups at 6 and 12 weeks postpartum. Multiple logistic regression was used to study the relationship between breastfeeding self-regulated motivation and the duration of breastfeeding at follow-up.

RESULTS

At 6 and 12 weeks postpartum, women who breastfed exclusively scored significantly higher in self-regulated motivation than those who formula-fed. The self-regulated motivation was associated with higher odds of exclusive breastfeeding at 6 weeks and any breastfeeding at 12 weeks postpartum.

CONCLUSIONS FOR PRACTICE

The study found that self-regulated motivation was positively related to breastfeeding duration. Maternal self-regulated motivation toward breastfeeding could be enhanced by the availability of social support and breastfeeding-friendly facilities, resulting in longer breastfeeding duration.

Young adults’ perceptions of breastfeeding in public: a focus group study

Objective

To elucidate the perceptions of young Chinese adults aged 18–25 toward adopting breastfeeding in public in Hong Kong Special Administrative Region (Hong Kong), China.

Methods

A descriptive and exploratory study design was adopted. Participants were recruited by convenience sampling. Focus group data were collected from three semi-structured interviews. Responses from 18 participants were audiotaped, transcribed verbatim, coded, and analyzed using content analysis.

Results

Four themes emerged that described the young adults’ perceptions and barriers toward breastfeeding practices: (1) adaptability of self and others, (2) cultural deem and practice, (3) convenience and connection, and (4) education and advocacy. Interestingly, all respondents (male and female) are aware of the benefits of breastfeeding. Their negative perceptions toward breastfeeding initiation and continuation originate from factors that are essentially extraneous to the mother–infant dyads (such as the breadth and intensity of sociopolitical support, the dominant social beliefs and norms, and the inadequacy of breastfeeding education in adolescent years).

Conclusions

In general, the young adult's perception of breastfeeding is dominated by sociopolitical and cultural-related factors. In particular, sexualization of breasts as a deep-rooted belief in the Chinese context negatively affects young adults’ perceptions and limits their breastfeeding practices.

Perceived enablers of exclusive breastfeeding by teenage mothers in Ghana

Background

Exclusive breastfeeding for the first 6 months can prevent diseases, boost immunity and improve quality of lives of infants. Ghana implemented programmes aimed at reaching the global target of increasing exclusive breastfeeding for the first 6 months to at least 50% by the year 2025. The country witnessed a decline in the overall rate of exclusive breastfeeding and an increase in the number of teenage mothers. Globally, teenage mothers are less likely to breastfeed than mothers of other age groups. Understanding enablers of exclusive breastfeeding by teenage mothers is important for any intervention aimed at improving exclusive breastfeeding rates and the quality of lives of infants.

Method

The study used a qualitative, exploratory, descriptive and contextual design, with focus groups. A total of six group discussions were conducted with 30 pregnant teenagers recruited from six public hospitals.

Results

Seven enablers emerged from the analysis of data. These included positive beliefs about the benefits of breast milk, family history of positive exclusive breastfeeding outcomes, support of the intimate partner, approval of closed-family members, expert opinions of antenatal care staff, teenage-oriented breastfeeding education and community-based breastfeeding education.

Conclusion

Health professionals and policy makers could learn from these enablers and use them to promote exclusive breastfeeding practices amongst teenage mothers in Ghana.

Association Between Intrapartum Factors and the Time to Breastfeeding Initiation

Background/Objectives: Early breastfeeding initiation is strongly recommended. Reasons for delayed breastfeeding initiation often include intrapartum interventions such as induction of labor, opioid pain medication administration, epidural analgesia, and caesarean birth. The majority of existing studies examining the timeliness of breastfeeding initiation are from low- or middle-income countries. The objective of this study is to examine intrapartum interventions on the time to breastfeeding initiation in a cohort of mothers from a high-income country. Materials and Methods: A cohort of 1,277 new mothers was recruited within 24 hours after birth from 4 hospitals in Hong Kong from 2011 to 2012. Participants completed a self-administered questionnaire immediately after recruitment. The rates of intrapartum interventions and the time to the first breastfeed were collected from participants' hospital record. Results: Among participants, 575 (45.5%) initiated breastfeeding within 1 hour of birth and the median time to the first breastfeed was 1.5 hours. The use of opioid pain medication (adjusted hazard ratio [aHR]: 0.78, 95% confidence interval [CI]: 0.67-0.91), assisted vaginal birth (aHR: 0.74, 95% CI 0.56-0.97), and caesarean section (aHR: 0.30, 95% CI 0.25-0.36) were associated with delayed breastfeeding, whereas epidural analgesia and induction of labor had no effect on breastfeeding initiation. Natural birth (i.e., no intrapartum interventions) was also significantly associated with early breastfeeding initiation (aHR: 1.75, 95% CI 1.54-1.99). Conclusions: Breastfeeding initiation was delayed in participants who had a caesarean birth and who received opioid pain medication. These women may require additional support to initiate breastfeeding soon after birth.

Exposure to baby-friendly hospital practices and mothers' achievement of their planned duration of breastfeeding

BACKGROUND

Both breastfeeding intentions and exposure to baby-friendly hospital practices were found to be associated with a longer duration of breastfeeding. This study aims to examine the effect of exposure to baby-friendly hospital practices on mothers' achievement of their planned duration of breastfeeding.

METHODS

A total of 1011 mother-newborn pairs from the postnatal units of four public hospitals in Hong Kong were recruited. Sociodemographic data and breastfeeding intention data were collected via self-report questionnaires during the postnatal hospitalization and exposure to Baby-Friendly hospital practices were assessed through hospital records and maternal self-report. Breastfeeding status after hospital discharge was assessed through telephone follow-up for up to 12 months postnatal, or until participants were no longer breastfeeding.

RESULTS

Only 55% (n = 552) of study participants achieved their intended duration of breastfeeding. Participants with higher socioeconomic status, previous breastfeeding experience, and those who had lived in Hong Kong for less than 5 years, were more likely to achieve their planned duration of breastfeeding. Among baby-friendly hospital practices, feeding only breast milk during the hospitalization and providing information about breastfeeding support on discharge were associated with participants' achieving their individual breastfeeding intentions. After adjustment, when compared with women who experienced onebaby-friendly practice, participants who experienced six baby-friendly hospital practices were significantly more likely to achieve their planned duration of breastfeeding (adjusted odds ratio = 8.45, 95% confidence interval 3.03-23.6).

CONCLUSIONS

Nearly half of participants did not achieve their planned breastfeeding duration. Exposure to baby-friendly hospital practices, especially in-hospital exclusive breastfeeding and providing breastfeeding support information upon hospital discharge may help more mothers to achieve their individual breastfeeding goals.

Do Differences in Prelacteal Feeding Explain Differences in Subsequent Breastfeeding Between Haiti and the Dominican Republic?

OBJECTIVE

Although Haiti and the Dominican Republic (DR) share the same island of Hispaniola, exclusive breastfeeding is much higher in Haiti. As prelacteal feeding also differs between the two countries, it was hypothesize that prelacteal feeding would account for the subsequent differences in breastfeeding exclusivity between the two countries, while controlling for other potentially influencing differences.

METHODS

Data for infants under 6 months of age were extracted from the cross-sectional Demographic and Health Surveys from Haiti (2012) and the DR (2013). Bivariate analysis and ordered logistic regression models were used.

RESULTS

Data were available for 686 Haitian infants [mean age: 2.9 (SD: 1.6) months] and 264 Dominican infants [mean age: 2.6 (SD: 1.6) months]. Haitian infants were more likely to be exclusively breastfed than Dominican infants, 41.3% versus 8.0%, at the time of the survey, and less likely to have been exposed to any prelacteal feeds, 20.1% versus 69.8%, respectively. Furthermore, Dominican infants were more likely to have been exposed to milk-based prelacteal feeds. Dominican status, any prelacteal feeds, and milk-based prelacteal feeds significantly and independently reduced the odds of breastfeeding exclusivity.

CONCLUSIONS FOR PRACTICE

Identification of factors beyond prelacteal feeding are necessary to explain the substantially lower breastfeeding exclusivity in the DR compared to Haiti and to determine why so many Dominican infants are exposed to milk-based prelacteal feeds.

Exclusive breastfeeding for the first six months of life and its associated factors among children age 6-24 months in Burao district, Somaliland

Background

Adequate nutrition during early childhood ensures growth and development of children and breast milk is better than any other products given to a child. However, studies on exclusive breastfeeding practice are limited in Somaliland. Therefore, this study was aimed to assess exclusive breastfeeding for the first 6 months of life and its associated factors among children 6–24 months of age in Burao district, Somaliland.

Methods

A community-based cross-sectional study was conducted from 26 August to 10 October 2018, in Burao district among randomly, selected 464 mothers with children 6–24 months of age. Data were collected through face-to-face interview using pretested structured questionnaire.

Results

The prevalence of exclusive breastfeeding was 20.47% (95% CI 18.84, 23.63%). Exclusive breastfeeding practice was associated with: having female child (AOR 0.48; 95% CI 0.29, 0.80)), lack of formal education (AOR 0.32; 95% CI 0.19, 0.53), household monthly income 100$-200$ (AOR 0.35;95% CI 0.18, 0.68), lack of husband’s support (AOR 0.32; 95% CI 0.19, 0.53), and mothers who were not counselled on breastfeeding during antenatal care (AOR = 0.33; 95% CI 0.16, 0.66).

Conclusions

Exclusive breastfeeding practice was very low as compared to recommendations of infant and young child practice (IYCF) which recommends children to exclusively breastfeed for the first 6 months of life. Exclusive breastfeeding practice was associated with a mother’s lack of formal education, monthly income less than 100$, being a female child, lack of advice on exclusive breastfeeding during antenatal care and lack of husband support. The promotion of education for women, husband’s engagement, encouraging antenatal care follow-up and counseling of exclusive breastfeeding during antenatal care was recommended to improve exclusive breastfeeding practice.

Consequences of Lack of Neonatal Breastfeeding in Infants Hospitalized for Diarrhea at an Urban Hospital, Bangladesh: A Case Control Design

Background. Exclusive breastfeeding is important for immunity and lack of breastfeeding during the neonatal age impedes that. Our aim was to assess the consequences of lack of breastfeeding on infants with diarrhea in the neonatal period. Methods. In this design, infants from DDSS (Diarrheal Disease Surveillance System) from 2009 to 2013 were studied. Those who did not have breastfeeding or had cessation of breastfeeding at the neonatal age constituted the cases, whereas infants who continued breastfeeding since birth or for at least 6 months since birth constituted the controls. Results. The cases more often presented at a younger age, had an illiterate mother, frequently presented with complicated diarrhea, had severe wasting, and had abnormal mental status compared with the controls. In logistic regression, after adjusting for potential confounders, infants who lacked breastfeeding at the neonatal period had an independent association with dehydrating diarrhea. Conclusions. The results of our analyses suggest that infants with diarrhea who did not have breastfeeding at the neonatal age are prone to develop some or severe dehydration.

Knowledge and attitudes towards breastfeeding practices: A cross-sectional survey of postnatal mothers in China

OBJECTIVE

To examine the mothers' knowledge and attitudes toward breastfeeding and highlight barriers to exclusive breastfeeding in Chinese postpartum mothers.

DESIGN

Cross sectional survey SETTING: Maternity wards of two large, multi-service teaching hospitals, Wuhan, China.

PARTICIPANTS

324 postnatal mothers completed a structured questionnaire during their stay at hospital from October 2016 to January 2017.

MEASUREMENTS AND FINDINGS

Descriptive and inferential statistics revealed that most mothers showed neutral attitude on breastfeeding and neutral knowledge level as well. The average score for the total Iowa Infant Feeding Attitude Scale (IIFAS) was 56.55±4.77 M±SD, and 10.83±2.77, M±SD for the knowledge section. The mothers who had poor knowledge were less likely to initiate breastfeeding within an hour after birth.

CONCLUSIONS

The results of this study are applicable to nurses and nurse midwives to assist in identification of women who may be at-risk to not initiate breastfeeding. Maternal positive attitude and good knowledge play key roles in the process of breastfeeding. Thus, it is important to provide antenatal and early postpartum education and periodical breastfeeding counselling, especially for new mothers, to improve maternal attitudes and knowledge toward breastfeeding practices.

Early childhood exposure to secondhand smoke and behavioural problems in preschoolers

Evidence on behavioural abnormalities in children exposed to secondhand smoke is limited. This study examined the relation between infant/ toddler cotinine concentration, a biomarker of secondhand smoke exposure, and behavioural problems in preschoolers who were unexposed to maternal smoking during gestation. A prospective cohort of 301 non-smoking mothers with their young children aged ≤18 months visiting postnatal primary care clinics in Hong Kong was enrolled in 2012 and followed by telephone survey 3 years afterwards. Saliva was collected at baseline for cotinine assay. Child behavioural health at 3-year follow-up was assessed by the parent-reported Strengths and Difficulties Questionnaire (SDQ). We conducted multivariable linear regressions to compute regression coefficients (b) of SDQ scores in relation to salivary cotinine level. Mean ± SD age of children at follow-up was 3.7 ± 0.5 years and 50.8% were boys. After adjusting for age, sex, birthweight, household income, housing type, maternal education and depressive symptoms, greater cotinine concentrations during early childhood were associated with greater conduct problems (b = 0.90, 95% CI 0.03-1.76) and hyperactivity/ inattention (b = 1.12, 95% CI 0.07-2.17) at preschool age. This study corroborates previous findings on the potential role of secondhand smoke in development of child behavioural problems.

Baby-friendly hospital practices are associated with duration of full breastfeeding in primiparous but not multiparous Iranian women

There is evidence that the Baby-Friendly Hospital Initiative (BFHI) results in improved breastfeeding outcomes in Western countries, but little is known of its impact in Middle-Eastern countries. This study investigated the impact of BFHI practices on duration of full breastfeeding in a cohort of 700 Iranian mothers recruited between June 2014 and March 2015 from maternity hospitals in Shiraz and followed-up prospectively for 6 months. At baseline, mothers self-reported exposure to 7 of the BFHI Ten Steps to Successful Breastfeeding (Steps 3 to 9). Data on breastfeeding outcomes were collected at baseline, 1, 3, 4, and 6 months postpartum. Cox regression analysis was conducted to determine the impact of individual and cumulative BFHI Steps on the duration of full breastfeeding, defined as the number of weeks since discharge that an infant received only breast milk and no complementary formula or food. Mothers reported experiencing on average 3.9 (SD 1.13, range 1 to 7) Steps, and only 28% of infants were fully breastfed at 6 months. There was a protective inverse relationship for primiparous (p for trend = .022) but not multiparous mothers (p for trend = .069), between the number of Steps a woman was exposed to and the likelihood of her discontinuing full breastfeeding within 6 months postpartum. Greater exposure to BFHI practices potentially could increase primiparous mothers' chances of fully breastfeeding to 6 months. Continual monitoring of the BFHI Steps and repeated education of healthcare staff are required to ensure that Iranian mothers receive adequate breastfeeding support.

Women’s experiences of formula feeding their infants: an interpretative phenomenological study

Objective

This study aimed to explore the experiences of women in the process of formula feeding their infants. The World Health Organization has emphasized the importance of breastfeeding for infant health. After decades of breastfeeding promotions, breastfeeding rates in Hong Kong have been rising consistently; however, the low continuation rate is alarming. This study explores women’s experiences with formula feeding their infants, including factors affecting their decision to do so.

Methods

A qualitative approach using an interpretative phenomenological analysis (IPA) was adopted as the study design. Data were collected from 2014 to 2015 through individual in-depth unstructured interviews with 16 women, conducted between 3 and 12 months after the birth of their infant. Data were analyzed using IPA.

Results

Three main themes emerged as follows: (1) self-struggle, with the subthemes of feeling like a milk cow and feeling trapped; (2) family conflict, with the subtheme of sharing the spotlight; and (3) interpersonal tensions, with the subthemes of embarrassment, staring, and innocence. Many mothers suffered various stressors and frustrations during breastfeeding. These findings suggest a number of pertinent areas that need to be considered in preparing an infant feeding campaign.

Conclusions

The findings of this study reinforce our knowledge of women’s struggles with multiple sources of pressure, such as career demands, childcare demands, and family life after giving birth. All mothers should be given assistance in making informed decisions about the optimal approach to feeding their babies given their individual situation and be provided with support to pursue their chosen feeding method.

The impact of immigration on the breastfeeding practices of Mainland Chinese immigrants in Hong Kong

BACKGROUND

Researchers have found breastfeeding disparities between immigrant and native-born women in many countries. However, most studies on immigration and breastfeeding practices have been in Western countries. The aim of this study was to examine the effect of length of time since immigration on the breastfeeding practices of Mainland Chinese immigrants living in Hong Kong.

METHODS

We recruited 2704 mother-infant pairs from the postnatal wards of four public hospitals in Hong Kong. We examined the effect of migration status on the duration of any and exclusive breastfeeding.

RESULTS

Breastfeeding duration was progressively shorter as the time since immigration increased. When compared with mothers who had lived in Hong Kong for <5 years, Hong Kong-born participants had a 30% higher risk of stopping any breastfeeding (hazard ratio [HR] 1.34 [95% confidence interval {CI} 1.10-1.63]) and exclusive breastfeeding (HR 1.33 [95% CI 1.11-1.58]). In both Hong Kong-born and immigrant participants, breastfeeding cessation was associated with return to work postpartum and the husband's preference for infant formula or mixed feeding. Intention to exclusively breastfeed and to breastfeed for >6 months, and previous breastfeeding experience substantially reduced the risk of breastfeeding cessation for both Hong Kong-born and immigrant participants.

CONCLUSIONS

Health care professionals should consider immigration history in their assessment of pregnant women and provide culturally adapted breastfeeding support and encouragement to this population.

Reasons for non-exclusive breast-feeding in the first 6 months

BACKGROUND

Maternal sociodemographic, delivery- and infant-related factors as well as hospital practice are relevant for breast-feeding practice. The aim of this study was to identify the sociodemographic and delivery-related factors that may affect exclusive breast-feeding (EBF) of infants aged 0-6 months in Poland.

METHODS

A total of 446 mothers (18-42 years old) of infants aged 0-6 months were interviewed using the computer-assisted Web interview method. The questionnaire collected information about maternal sociodemographic situation and anthropometrics, delivery-related factors, and infant feeding-related factors. Data were analyzed using the chi-squared test and Mann-Whitney U-test. Predictors of non-exclusive breast-feeding (N-EBF) in the first 6 months of life were assessed on multivariate logistic regression.

RESULTS

A total of 43% of mothers did not breast-feed exclusively (n = 191; N-EBF group) and 57% did breast-feed exclusively during the study period (n = 255; EBF group). After adjustment for other potential risk factors, the highest risk factors for N-EBF were maternal age <20 years (OR, 6.12; P ≤ 0.01), and inadequate breast-feeding knowledge (OR, 3.43; P ≤ 0.01), whereas the lowest risk was associated with pre-pregnancy intention to breast-feed (OR, 0.35; P ≤ 0.01), very good knowledge about breast-feeding (OR, 0.45; P ≤ 0.001) and maternal age 26-30 years (OR, 0.48; P ≤ 0.001). In a multivariate model, maternal education, employment status and preterm delivery were no longer statistically significant.

CONCLUSIONS

Breast-feeding practice is influenced by a variety of factors, including sociodemographic and psychosocial conditions, maternal obesity and mode of delivery. Further work is needed to establish the role of education and prophylactic programs in modifying the aforementioned risk factors.

Effect of Secondary Cigarette Smoke from Household Members on Breastfeeding Duration: A Prospective Cohort Study

OBJECTIVE

Maternal smoking and exposure to tobacco smoke is one modifiable risk factor that affects breastfeeding initiation and duration. We prospectively examine the effects of maternal and paternal smoking and other family members' smoking status on the duration of breastfeeding.

MATERIALS AND METHODS

A cohort of 1,277 mother-infant pairs admitted to the postpartum units of four major public hospitals in Hong Kong. Demographic data, maternal, paternal and household smoking habits, and other potential confounding variables were collected via self-reported questionnaires during the postnatal hospitalization. Breastfeeding status after hospital discharge was assessed through telephone follow-up up to 12 months postpartum, or until participants were no longer breastfeeding. If the participant had weaned during that follow-up interval, she was asked to report the total duration (in weeks) of both any and exclusive breastfeeding.

RESULTS

A total of 1,240 (97%) mother-infant pairs completed followed up, 2.5% were smokers, 29.2% of their partners smoked, and 11.3% had another smoker living in their home. Maternal and other family members' smoking predicted breastfeeding cessation. When compared with mothers in nonsmoking family, those exposed to two or more family members who smoked had approximately a 30% increased risk of breastfeeding cessation (adjusted hazard ratio [aHR] = 1.31; 95% CI 1.01-1.68).

CONCLUSION

Mothers who were exposed to two or more smokers in the household had a significantly shorter duration of any breastfeeding at 12-month follow-up.

Family members' infant feeding preferences, maternal breastfeeding exposures and exclusive breastfeeding intentions

BACKGROUND

Maternal breastfeeding intentions are strongly associated with breastfeeding exclusivity and duration. Factors that affect new mothers' exclusive breastfeeding intentions have not been adequately examined.

OBJECTIVE

The purpose of this study was to examine the association between family member's infant feeding preferences, breastfeeding exposures, and womens' exclusive breastfeeding intentions.

METHODS

1277 breastfeeding mother-infant pairs were recruited from four public hospitals in Hong Kong. We used multiple logistic and linear regression models to explore the impact of the family members' infant feeding preferences and breastfeeding exposures on exclusive breastfeeding intentions.

RESULTS

78.1% mothers reported an intention to exclusively breastfeed, and the median intended duration of exclusive breastfeeding was 26 weeks. The husband's preference for breastfeeding (aOR = 1.67; 95% CI 1.20-2.31), previous breastfeeding experience (aOR = 1.56; 95% CI 1.10-2.23) and attendance at an antenatal breastfeeding class (aOR = 2.09; 95% CI 1.45-3.02) were all strongly associated with higher maternal intention to exclusively breastfeed. For every additional family member who preferred breastfeeding, the odds of intending to exclusively breastfeed increased by 32% (aOR1.32; 95% CI, 1.13-1.55). Similarly, the proportion of participants intending to exclusively breastfeed increased progressively with more breastfeeding exposures.

CONCLUSIONS

Including fathers and other significant family members in antenatal breastfeeding education can help to maximize breastfeeding support for the new mother and encourage new mothers to exclusively breastfeed.

Practices, predictors and consequences of expressed breast-milk feeding in healthy full-term infants

Objective

To investigate the prevalence and predictors of expressed breast-milk feeding in healthy full-term infants and its association with total duration of breast-milk feeding.

Design

Prospective cohort study.

Setting

In-patient postnatal units of four public hospitals in Hong Kong.

Subjects

A total of 2450 mother–infant pairs were recruited in 2006–2007 and 2011–2012 and followed up prospectively for 12 months or until breast-milk feeding had stopped.

Results

Across the first 6 months postpartum, the rate of exclusive expressed breast-milk feeding ranged from 5·1 to 8·0 % in 2006–2007 and from 18·0 to 19·8 % in 2011–2012. Factors associated with higher rate of exclusive expressed breast-milk feeding included supplementation with infant formula, lack of previous breast-milk feeding experience, having a planned caesarean section delivery and returning to work postpartum. Exclusive expressed breast-milk feeding was associated with an increased risk of early breast-milk feeding cessation when compared with direct feeding at the breast. The hazard ratio (95 % CI) ranged from 1·25 (1·04, 1·51) to 1·91 (1·34, 2·73) across the first 6 months.

Conclusions

Mothers of healthy term infants should be encouraged and supported to feed directly at the breast. Exclusive expressed breast-milk feeding should be recommended only when medically necessary and not as a substitute for feeding directly at the breast. Further research is required to explore mothers’ reasons for exclusive expressed breast-milk feeding and to identify the health outcomes associated with this practice.
