Background: There is an increasing prevalence of expressed human milk feeding. The reasons for expressed human milk feeding of healthy term infants may differ from those for preterm infants. The process of adopting expressed human milk feeding for healthy full-term infants has not been well-described in the existing literature. Research Aim: To describe the reasons for, and antecedents to, expressed human milk feeding among Chinese women who used a high proportion of expressed human milk for feeding. Methods: A descriptive, prospective cross-sectional qualitative design was used. Participants ( N = 25) who used a high proportion of expressed human milk feeding were recruited from a larger perspective cohort study in two public hospitals in Hong Kong. Semi-structured, in-depth, one-to-one interviews were conducted 2017–2018. Data collection and thematic analysis were guided by the Breastfeeding Self-Efficacy Theory. Results: The authors conducted thematic analysis and identified six core themes: (1) perceived maternal roles; (2) breastfeeding role models; (3) negative feedback from social networks; (4) negative direct breastfeeding experiences; (5) expressed human milk feeding as a solution to a problem; and (6) advice from health care professionals to express human milk. These themes were consistent with the four antecedents of the Breastfeeding Self-Efficacy Theory (e.g., physiological and affective state, vicarious experiences, performance accomplishments, and verbal persuasion). Conclusions: The main reason for participants to feed expressed human milk was experiencing difficulties with direct breastfeeding. Expressed human milk feeding was used as an immediate solution for breastfeeding problems. Strengthening breastfeeding support in the early postpartum period may decrease the perceived need for human milk expression.

To explore factors associated with depression and COVID-19 related fear among pregnant women and new mothers.A cross-sectional survey was conducted in China from July 2020 to July 2021.A total of 3027 pregnant and new mothers were recruited.Sociodemographic characteristics and the perceptions of the COVID-19 pandemic were collected. The Patient Health Questionnaire-9 (PHQ-9) and the Fear Scale was used to assess the depressive and fear level towards the COVID-19 pandemic, respectively.Approximately 17.2% of the participants had depression (PHQ-9 ≥10). In Hong Kong, participants who perceived that they have increased knowledge to prevent infection were less likely to have depression (adjusted odds ratio [aOR] = 0.83; 95% confidence interval [CI] = 0.74-0.94). There was no association between perceived severity if infected and severity of spread and the depression level in our sample. An inverse relationship was found between the COVID-19 related fear level and perceived knowledge to prevent infection (Beta-coefficient [β] = -0.20; 95% CI = -0.38 to -0.02).Public health nurses need to promote accurate and up to date COVID-19 related information at clinical and community settings and implement effective screening for depression and fear symptoms to identify these high-risk groups to improve women's psychological well-being.

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.

Background Expressed breast milk feeding has increased substantially in the past two decades. Once used primarily for preterm infants, feeding expressed breast milk is now more common in mothers giving birth to healthy term infants. However, the effect of expressed breast milk feeding on breastfeeding duration is unclear. Objectives To assess the association between breast milk expression practices and breastfeeding duration in women giving birth to healthy infants. Methods From 2017 to 2018, we recruited 821 new mothers from two public hospitals in Hong Kong. Participants were followed up at 1.5, 3, and 6 months postpartum or until they stopped breastfeeding. The proportion, type, and mode of all milk feeding were assessed at each follow-up. Results At 1.5 months postpartum, 47.9%, 37.7%, and 14.4% of participants were feeding by direct breastfeeding only, mixed-mode feeding, and expressed breast milk only, respectively. Participants feeding expressed breast milk only were more likely to be supplementing with infant formula. When compared with participants who provided only direct breastfeeding, participants who gave only expressed breast milk at 1.5 months had 57% lower odds of breastfeeding continuation at three months postpartum. After stratification by infant formula supplementation, expressed breast milk feeding only at 1.5 months was associated with an increased risk of breastfeeding cessation in participants supplementing with infant formula (adjusted hazard ratio [aHR] = 1.86, 95% CI = 1.17–2.95). Conclusion In the first six months postpartum, giving only expressed breast milk is associated with early breastfeeding cessation, especially in participants who are also supplementing with infant formula.

Background Gestational diabetes mellitus is associated with adverse maternal and fetal outcomes and increases subsequent risk of Type 2 diabetes. Researchers have shown that breastfeeding may reduce diabetes risk in women with recent gestational diabetes. Research aim To assess association between infant feeding and postpartum glucose tolerance in mothers with recent gestational diabetes within 1 year postpartum. Methods A literature search was performed up to December 31, 2019, retrieving articles related to infant feeding, gestational diabetes, and postpartum glucose regulation in four major databases (PubMed, Cochrane, CINAHL, and Embase). Methodological quality was assessed using tools from the United States National Institutes of Health and the National Heart, Lung, and Blood Institute. Results The search yielded 15 cohort studies meeting the selection criteria. Of the 15 studies, 13 (86.7%) examined the influence of breastfeeding on postpartum glycemic status, and eight (53.4%) compared the mean blood glucose values between breastfeeding and non-breastfeeding participants. Of the 13 studies that compared postpartum glycemic status, nine (60%) of the research teams found that breastfeeding lowered rates of impaired glucose tolerance, and four (26.7%) showed no significant change. In eight of the studies reporting mean blood glucose values, six (75%) reported significantly lower fasting plasma glucose in breastfeeding participants, with reductions ranging from 3.7 to 7.4 mg/dL (0.2–0.4 mmol/L). Conclusion Breastfeeding has been associated with improved postpartum glucose regulation in mothers with gestational diabetes. In pregnant women with gestational diabetes, breastfeeding may reduce the risk of Type 2 diabetes, and women with gestational diabetes should be strongly encouraged and supported to breastfeed.

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.

Background Infants born early-term, between 37 weeks, 0 days and 38 weeks, 6 days of gestation, are more likely to have adverse health outcomes and to undergo interventions that could pose barriers to breastfeeding. The objectives of this review are to examine the effect of early-term birth on breastfeeding initiation and the duration of any and exclusive breastfeeding. Methods We systematically searched PubMed, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), EMBASE, and Scopus, from January 2007 to June 2017, for studies examining the associations between early-term birth and rates of breastfeeding initiation and the duration of any and exclusive breastfeeding. Results Nine studies were included in the review, of which four assessed breastfeeding initiation rates, eight assessed any breastfeeding duration and two assessed exclusive breastfeeding duration. Two studies found that early-term birth was associated with a lower rate of breastfeeding initiation and five studies reported an association between early-term birth and breastfeeding cessation. One study found that early-term birth was associated with a shorter duration of exclusive breastfeeding. Conclusion Although the majority of the reviewed studies reported that early-term infants were less likely to be breastfed and were more likely to be breastfed for a shorter duration, study quality varied and the duration of follow-up was short. Further research with longer follow-up would be beneficial to better understand the effect of early-term birth on breastfeeding.

Introduction There is an increasing prevalence of breast milk expression and expressed breast milk feeding in healthy full-term infants. The purpose of this study was to provide up-to-date evidence on the practice of expressed breast milk feeding and to identify factors associated with expressed breast milk feeding in Hong Kong Chinese mothers of healthy full-term infants. Method We used a prospective cohort study design to recruit 821 mothers who gave birth to healthy full-term infants in two public hospitals in Hong Kong. Participants completed self-administered baseline questionnaires during their postpartum stay and were followed-up by a series of telephone calls over a 6 months period or until they stopped breastfeeding, whichever came first. The proportion, mode, and type of infant feeding (direct breastfeeding, expressed breast milk feeding and infant formula feeding) were assessed at each telephone follow-up. Results In our sample, 14.6%, 20.2% and 15% of the participants fed expressed breast milk only to their infants at 1.5, 3 and 6 months respectively. Less than one-half were giving only direct breastfeeding only at 1.5 and 3 months. Within the first six months postpartum, 84.6% of the participants had given expressed breast milk. More than 80% of participants obtained a breast pump before giving birth, with the majority obtaining electric pumps. The most common reason for expressing breast milk within the first 1.5 months postpartum was experiencing breastfeeding difficulties (35%). Returning to employment was the strongest predictor of expressed breast milk feeding at three months postpartum (adjusted odds ratio [aOR]=8.71, 95% Confidence interval [CI]= 5.12–14.8). Conclusion A high proportion of Hong Kong Chinese mothers of healthy, full-term infants pump and feed expressed breast milk at some point during the first 6 months postpartum. Participants purchase or obtain breast pumps before giving birth, often in anticipation of breastfeeding difficulties and returning to work.

When compared with full-term birth (39 to42 weeks), early-term birth (37 to39 weeks) is associated with adverse neonatal outcomes that may impede breastfeeding. Breastfeeding provides numerous benefits to infants and could potentially offset the effects of early-term birth. However, the effect of early-term birth on any and exclusive breastfeeding duration among healthy normal weight infants is unclear.The objective of this study was to examine the association between early-term birth and breastfeeding duration and exclusivity among healthy term infants.Two prospective cohorts of 2704 healthy mother-infant pairs were recruited in Hong Kong in 2006-07 and 2011-12. Participants were followed prospectively for 12 months or until they stopped breastfeeding.Approximately one-third (32.8%) of the infants were born early-term. More than one-half of all participants had stopped breastfeeding by three months postpartum and approximately one-half of the infants were not being exclusively breastfed by two weeks postpartum. There was no significant difference in the odds of any (adjusted odds ratio [aOR] = 1.05; 95% 0.85, 1.31) or exclusive (aOR = 0.89; 95% 0.73, 1.08) breastfeeding at one-month postpartum between infants born early-term and at full-term. There was also no significant difference in the duration of any (adjusted hazard ratio [aHR] = 1.0; 95% 0.91, 1.10) or exclusive (aHR = 1.0; 95% 0.91, 1.09) breastfeeding between early-term and full-term infants.In this cohort, early-term birth was not associated with breastfeeding duration and exclusivity. This suggests that, in the absence of neonatal complications, early-term birth itself may not lead to a shorter duration of any or exclusive breastfeeding.

There has been a dramatic rise in preterm births in developed countries owing to changes in clinical practices and greater use of assisted reproductive techniques. However, few studies have examined the growth and outcomes of preterm infants according to the type of feeding (with fortified breast milk or formula). The purpose of this study was to examine the effect of breast milk feedings and formula on the growth and short-term outcomes of preterm infants in Hong Kong. In a single-center retrospective cohort study, we included 642 preterm infants at gestational age
