Fear in general populations: A cross-sectional study on perceived fear of common diseases, COVID-19, life events, and environmental threats in 30 countries.

Background: In this study, we assessed the general population's fears towards various diseases and events, aiming to inform public health strategies that balance health-seeking behaviours. Methods: We surveyed adults from 30 countries across all World Health Organization (WHO) regions between July 2020 and August 2021. Participants rated their fear of 11 factors on an 11-point Likert scale. We stratified the data by age and gender and examined variations across countries and regions through multidimensional preference analysis. Results: Of the 16 512 adult participants, 62.7% (n = 10 351) were women. The most feared factor was the loss of family members, reported by 4232 participants (25.9%), followed by cancer (n = 2248, 13.7%) and stroke (n = 1416, 8.7%). The highest weighted fear scores were for loss of family members (mean (x̄) = 7.46, standard deviation (SD) = 3.04), cancer (x̄ = 7.00, SD = 3.09), and stroke (x̄ = 6.61, SD = 3.24). The least feared factors included animals/insects (x̄ = 3.72, SD = 2.96), loss of a mobile phone (x̄ = 4.27, SD = 2.98), and social isolation (x̄ = 4.83, SD = 3.13). Coronavirus disease 2019 (COVID-19) was the sixth most feared factor (x̄ = 6.23, SD = 2.92). Multidimensional preference analyses showed distinct fears of COVID-19 and job loss in Australia and Burundi. The other countries primarily feared loss of family members, cancer, stroke, and heart attacks; this ranking was consistent across WHO regions, economic levels, and COVID-19 severity levels. Conclusions: Fear of family loss can improve public health messaging, highlighting the need for bereavement support and the prevention of early death-causing diseases. Addressing cancer fears is crucial to encouraging the use of preventive services. Fear of non-communicable diseases remains high during health emergencies. Top fears require more resources and countries with similar concerns should collaborate internationally for effective fear management.

Extended Paid Maternity Leave Associated With Improved Maternal Mental Health In Hong Kong.

In July 2020, Hong Kong extended statutory paid maternity leave from ten weeks to fourteen weeks to align with International Labour Organization standards. We used the policy enactment as an observational natural experiment to assess the mental health implications of this policy change on probable postnatal depression (Edinburgh Postnatal Depression Scores of 10 or higher) and postpartum emotional well-being. Using an opportunistic observational study design, we recruited 1,414 survey respondents with births before (August 1-December 10, 2020) and after (December 11, 2020-July 18, 2022) policy implementation. Participants had a mean age of thirty-two, were majority primiparous, and were mostly working in skilled occupations. Our results show that the policy was associated with a 22 percent decrease in mothers experiencing postnatal depressive symptoms and a 33 percent decrease in postpartum emotional well-being interference. Even this modest change in policy, an additional four weeks of paid leave, was associated with significant mental health benefits. Policy makers should consider extending paid maternity leave to international norms to improve mental health among working mothers and to support workforce retention.

Key lifestyles and health outcomes across 16 prevalent chronic diseases: A network analysis of an international observational study.

Background: Central and bridge nodes can drive significant overall improvements within their respective networks. We aimed to identify them in 16 prevalent chronic diseases during the coronavirus disease 2019 (COVID-19) pandemic to guide effective intervention strategies and appropriate resource allocation for most significant holistic lifestyle and health improvements. Methods: We surveyed 16 512 adults from July 2020 to August 2021 in 30 territories. Participants self-reported their medical histories and the perceived impact of COVID-19 on 18 lifestyle factors and 13 health outcomes. For each disease subgroup, we generated lifestyle, health outcome, and bridge networks. Variables with the highest centrality indices in each were identified central or bridge. We validated these networks using nonparametric and case-dropping subset bootstrapping and confirmed central and bridge variables' significantly higher indices through a centrality difference test. Findings: Among the 48 networks, 44 were validated (all correlation-stability coefficients >0.25). Six central lifestyle factors were identified: less consumption of snacks (for the chronic disease: anxiety), less sugary drinks (cancer, gastric ulcer, hypertension, insomnia, and pre-diabetes), less smoking tobacco (chronic obstructive pulmonary disease), frequency of exercise (depression and fatty liver disease), duration of exercise (irritable bowel syndrome), and overall amount of exercise (autoimmune disease, diabetes, eczema, heart attack, and high cholesterol). Two central health outcomes emerged: less emotional distress (chronic obstructive pulmonary disease, eczema, fatty liver disease, gastric ulcer, heart attack, high cholesterol, hypertension, insomnia, and pre-diabetes) and quality of life (anxiety, autoimmune disease, cancer, depression, diabetes, and irritable bowel syndrome). Four bridge lifestyles were identified: consumption of fruits and vegetables (diabetes, high cholesterol, hypertension, and insomnia), less duration of sitting (eczema, fatty liver disease, and heart attack), frequency of exercise (autoimmune disease, depression, and heart attack), and overall amount of exercise (anxiety, gastric ulcer, and insomnia). The centrality difference test showed the central and bridge variables had significantly higher centrality indices than others in their networks (P < 0.05). Conclusion: To effectively manage chronic diseases during the COVID-19 pandemic, enhanced interventions and optimised resource allocation toward central lifestyle factors, health outcomes, and bridge lifestyles are paramount. The key variables shared across chronic diseases emphasise the importance of coordinated intervention strategies.

Key lifestyles and interim health outcomes for effective interventions in general populations: A network analysis of a large international observational study.

Background: The interconnected nature of lifestyles and interim health outcomes implies the presence of the central lifestyle, central interim health outcome and bridge lifestyle, which are yet to be determined. Modifying these factors holds immense potential for substantial positive changes across all aspects of health and lifestyles. We aimed to identify these factors from a pool of 18 lifestyle factors and 13 interim health outcomes while investigating potential gender and occupation differences. Methods: An international cross-sectional study was conducted in 30 countries across six World Health Organization regions from July 2020 to August 2021, with 16 512 adults self-reporting changes in 18 lifestyle factors and 13 interim health outcomes since the pandemic. Results: Three networks were computed and tested. The central variables decided by the expected influence centrality were consumption of fruits and vegetables (centrality = 0.98) jointly with less sugary drinks (centrality = 0.93) in the lifestyles network; and quality of life (centrality = 1.00) co-dominant (centrality = 1.00) with less emotional distress in the interim health outcomes network. The overall amount of exercise had the highest bridge expected influence centrality in the bridge network (centrality = 0.51). No significant differences were found in the network global strength or the centrality of the aforementioned key variables within each network between males and females or health workers and non-health workers (all P-values >0.05 after Holm-Bonferroni correction). Conclusions: Consumption of fruits and vegetables, sugary drinks, quality of life, emotional distress, and the overall amount of exercise are key intervention components for improving overall lifestyle, overall health and overall health via lifestyle in the general population, respectively. Although modifications are needed for all aspects of lifestyle and interim health outcomes, a larger allocation of resources and more intensive interventions were recommended for these key variables to produce the most cost-effective improvements in lifestyles and health, regardless of gender or occupation.

Experiences of expressed human milk feeding: A qualitative study.

OBJECTIVE: The objective of this study was to understand and describe the breastfeeding experiences of Chinese women with a high proportion of expressed human milk feeding. METHODS: A qualitative descriptive design was used to describe the usual practices of expressed human milk feeding among breastfeeding women. We conducted semi-structured, in-depth, one-to-one interviews with participants (N = 25) who had a high proportion of expressed human milk feeding. Thematic analysis was used to analyze the data. RESULTS: We identified three main themes: a sense of control, a sense of security, and milk expression challenges. Participants described that expressed human milk feeding provided a greater sense of control over their time and provided more freedom as they were no longer restricted by their infant's feeding schedule. Furthermore, knowing the amount of milk and having a stored milk supply provided a sense of security. However, providing expressed human milk can be time-consuming and has a lower intimacy level when compared with direct breastfeeding. CONCLUSION: Expressed human milk feeding can provide a greater sense of control and was used as an immediate solution to direct breastfeeding problems. However, some participants experienced challenges in expressed human milk feeding, and some preferred breastfeed directly. Therefore, it is crucial to strengthen the breastfeeding support provided in the early postpartum period to ensure that all breastfeeding persons can breastfeed directly.

Global impacts of COVID-19 on lifestyles and health and preparation preferences: An international survey of 30 countries.

Background: The health area being greatest impacted by coronavirus disease 2019 (COVID-19) and residents' perspective to better prepare for future pandemic remain unknown. We aimed to assess and make cross-country and cross-region comparisons of the global impacts of COVID-19 and preparation preferences of pandemic. Methods: We recruited adults in 30 countries covering all World Health Organization (WHO) regions from July 2020 to August 2021. 5 Likert-point scales were used to measure their perceived change in 32 aspects due to COVID-19 (-2 = substantially reduced to 2 = substantially increased) and perceived importance of 13 preparations (1 = not important to 5 = extremely important). Samples were stratified by age and gender in the corresponding countries. Multidimensional preference analysis displays disparities between 30 countries, WHO regions, economic development levels, and COVID-19 severity levels. Results: 16 512 adults participated, with 10 351 females. Among 32 aspects of impact, the most affected were having a meal at home (mean (m) = 0.84, standard error (SE) = 0.01), cooking at home (m = 0.78, SE = 0.01), social activities (m = -0.68, SE = 0.01), duration of screen time (m = 0.67, SE = 0.01), and duration of sitting (m = 0.59, SE = 0.01). Alcohol (m = -0.36, SE = 0.01) and tobacco (m = -0.38, SE = 0.01) consumption declined moderately. Among 13 preparations, respondents rated medicine delivery (m = 3.50, SE = 0.01), getting prescribed medicine in a hospital visit / follow-up in a community pharmacy (m = 3.37, SE = 0.01), and online shopping (m = 3.33, SE = 0.02) as the most important. The multidimensional preference analysis showed the European Region, Region of the Americas, Western Pacific Region and countries with a high-income level or medium to high COVID-19 severity were more adversely impacted on sitting and screen time duration and social activities, whereas other regions and countries experienced more cooking and eating at home. Countries with a high-income level or medium to high COVID-19 severity reported higher perceived mental burden and emotional distress. Except for low- and lower-middle-income countries, medicine delivery was always prioritised. Conclusions: Global increasing sitting and screen time and limiting social activities deserve as much attention as mental health. Besides, the pandemic has ushered in a notable enhancement in lifestyle of home cooking and eating, while simultaneously reducing the consumption of tobacco and alcohol. A health care system and technological infrastructure that facilitate medicine delivery, medicine prescription, and online shopping are priorities for coping with future pandemics.

A Qualitative Exploration of the Reasons for Expressed Human Milk Feeding Informed by the Breastfeeding Self-Efficacy Theory.

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.

The Association Between Breastfeeding Self-Efficacy and Mode of Infant Feeding.

Introduction: It is well established that low breastfeeding self-efficacy is associated with early breastfeeding cessation. Over the past several decades, expressed human milk feeding has increased among parents of healthy infants. Researchers have hypothesized an association between maternal breastfeeding confidence and expressed human milk feeding, but it has not been empirically examined. Therefore, the primary objective of this study was to assess the associations between breastfeeding self-efficacy and human milk expression practices. The secondary objective was to assess the effect of breastfeeding self-efficacy on breastfeeding duration and exclusivity. Methods: This study used a prospective cohort design. From 2017 to 2018, we recruited 821 healthy mothers with term births in two public hospitals in Hong Kong. Participants completed a self-administered questionnaire in the immediate postpartum period, which gathered information about sociodemographic characteristics and Breastfeeding Self-Efficacy Scale-Short Form (BSES-SF). Participants were followed up for 6 months or until infants were weaned. The proportion and type of infant feeding were assessed at telephone follow-up. Results: The overall mean BSES-SF score in our sample was 46.5 (standard deviation = 10.1). Every one-point increase in the BSES-SF score was associated with 4-5% lower risk of any expressed human milk feeding and 4-7% higher odds of breastfeeding continuation across the first 6 months postpartum. Conclusion: Higher breastfeeding self-efficacy is associated with a lower risk of expressed human milk feeding and a longer duration of any and exclusive breastfeeding. Further studies should explore how improving breastfeeding self-efficacy may affect the mode of human milk feeding.

The Influence of the Baby-Friendly Hospital Initiative and Maternity Care Practices on Breastfeeding Outcomes.

BACKGROUND: The Baby-Friendly Hospital Initiative (BFHI) was launched in 1991 to promote breastfeeding through hospital policy. Researchers have reported breastfeeding improvements after hospitals became "Baby-Friendly." In Hong Kong, the first public hospital was designated as a Baby-Friendly Hospital in 2016. RESEARCH AIM: To examine the influence of the BFHI on breastfeeding by comparing breastfeeding outcomes in a study cohort recruited before the implementation of the BFHI and a cohort recruited after its implementation. METHODS: This was a quasi-experimental interrupted time-series design. Two cohorts of mother-infant pairs (N = 2369) were recruited immediately postpartum from four public hospitals in Hong Kong and followed up prospectively. Comparisons were made in five of the BFHI steps experienced in both cohorts and the duration of any and exclusive breastfeeding. RESULTS: A higher proportion of participants from the post-implementation cohort breastfed and breastfed exclusively at all follow-up periods. Participants in the pre-BFHI cohort, on average experienced 3.10 (SD = 1.42) of the BFHI steps, whereas the participants in the post-BFHI cohort experienced 3.59 (1.09) of the BFHI steps. Half of the participants discontinued any breastfeeding by 13 weeks in the pre-BFHI cohort; more than half in the post-BFHI cohort were still breastfeeding at 6 months postpartum (p < .001). Giving only human milk in the first 48 hr of delivery and not providing pacifiers or bottles were associated with lower risk of not exclusive breastfeeding in both cohorts. CONCLUSION: Implementation of the BFHI was associated with improvements in breastfeeding practices and outcomes.

Association between expressed breast milk feeding and breastfeeding duration in Hong Kong mothers.

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.

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.

International survey on fear and childbirth experience in pregnancy and the postpartum period during the COVID-19 pandemic: study protocol.

INTRODUCTION: The COVID-19 pandemic has caused unprecedented disruptions around the world. Adding to the existing stress surrounding pregnancy and childbirth, the threat of infection and social isolation policies may negatively impact pregnant women and new mothers. Literature on the effect of COVID-19 on fear during pregnancy and childbirth experience is limited. As the COVID-19 pandemic continues to affect the global population, it is important to understand how it has impacted pregnant women and new mothers' experiences worldwide to inform perinatal care and interventions. METHODS AND ANALYSIS: This multicountry study involving China and Canada targets to recruit 1000 pregnant women and new mothers who gave birth since 2020 in each participating country. Participants will be recruited online in the local language through mothers' groups, antenatal and postnatal clinics and hospital wards. All questionnaires will be completed online. Participants' level of fear, depression and childbirth experience will be assessed along with other sociodemographic, medical and COVID-related measures. Regression models will be used to compare the outcomes among the participating countries. ETHICS AND DISSEMINATION: The study has been reviewed and approved by the institutional review boards of the participating countries. Findings will be disseminated in peer-reviewed journals and academic conferences. Results from this study may guide the formulation of future health guidelines and policies in the face of a pandemic.

International survey for assessing COVID-19's impact on fear and health: study protocol.

INTRODUCTION: COVID-19, caused by the SARS-CoV-2, has been one of the most highly contagious and rapidly spreading virus outbreak. The pandemic not only has catastrophic impacts on physical health and economy around the world, but also the psychological well-being of individuals, communities and society. The psychological and social impacts of the COVID-19 pandemic internationally have not been well described. There is a lack of international study assessing health-related impacts of the COVID-19 pandemic, especially on the degree to which individuals are fearful of the pandemic. Therefore, this study aims to (1) assess the health-related impact of the COVID-19 pandemic in community-dwelling individuals around the world; (2) determine the extent various communities are fearful of COVID-19 and (3) identify perceived needs of the population to prepare for potential future pandemics. METHODS AND ANALYSIS: This global study involves 30 countries. For each country, we target at least 500 subjects aged 18 years or above. The questionnaires will be available online and in local languages. The questionnaires include assessment of the health impacts of COVID-19, perceived importance of future preparation for the pandemic, fear, lifestyles, sociodemographics, COVID-19-related knowledge, e-health literacy, out-of-control scale and the Patient Health Questionnaire-4. Descriptive statistics will be used to describe participants' characteristics, perceptions on the health-related impacts of COVID-19, fear, anxiety and depression, lifestyles, COVID-19 knowledge, e-health literacy and other measures. Univariable and multivariable regression models will be used to assess the associations of covariates on the outcomes. ETHICS AND DISSEMINATION: The study has been reviewed and approved by the local ethics committees in participating countries, where local ethics approval is needed. The results will be actively disseminated. This study aims to map an international perspective and comparison for future preparation in a pandemic.

An Interactive Web-Based Sexual Health Literacy Program for Safe Sex Practice for Female Chinese University Students: Multicenter Randomized Controlled Trial.

BACKGROUND: Sexual health concerns among young adults worldwide help to motivate preventative practices against sexually transmitted infections. To foster better sexual health, sexual health literacy must be enhanced. Little research has been conducted on the impact of gender power dynamics on sexual health, such as sexual coercion, even though the prevalence of sexual coercion remains high in China. OBJECTIVE: This study describes the development and systematic evaluation of a web-based sexual health literacy intervention called "Smart Girlfriend" for female Chinese university students. METHODS: A multicenter randomized controlled trial was conducted with 781 female university students at 5 universities with dormitories in Hong Kong. Inclusion criteria were used to select unmarried, female, Chinese university students who were ≥18 years old and had not received a sexual health intervention in the past 12 months. Participants were randomly assigned to 2 groups: one group received an interactive web-based sexual health literacy intervention and the other group received a single webpage of online information about condom use. The intervention content was based on the Health Belief Model and the Continuum of Conflict and Control theory. The primary outcome was self-reported consistency of condom use with every partner at 3-month and 6-month follow-up assessments, analyzed using zero/one inflated beta (ZOIB) regression. The secondary outcome was an appraisal of the knowledge, attitudes, norms, and self-efficacy of condom use using the 25-item Multidimensional Condom Attitudes Scale (MCAS). The intention to treat was applied in analyses. RESULTS: Of 1503 individuals that were screened, 781 (52%) were randomized into 2 groups. The retention rates at the 3-month and 6-month follow-ups were 92% and 91%, respectively. Most participants were born locally (536/746, 72%), and 18% (134/746) self-reported as a sexual minority. ZOIB results regarding the consistency of condom use were not significant [model 1: odds ratio (OR) 2.25 with a 95% credible interval (CrI) of 0.84-6.36; model 2: OR 8.03 (95% CrI 0.22-330.31); model 3: OR 1.21 (95% CrI 0.78-1.86)]. Consistency in the intervention group was 5% higher (95% CI -1.90 to 11.63) than the control group at the 3-month follow-up, and 1% higher (95% CI -5.81 to 8·02) at the 6-month follow-up. MCAS scores at the 3-month follow-up were significantly higher in the intervention group (mean 122.51, SD 15.97) than the control group (mean 119.86, SD 15.85; P=.02). CONCLUSIONS: An interactive web-based sexual health literacy program did not significantly increase the consistency of condom use compared to a single webpage of condom use information; however, it did temporarily improve knowledge, attitudes, norms, and self-efficacy regarding condom use. Future revisions of this intervention should be personalized and delivered with a proactive approach.

Breastfeeding and Postpartum Glucose Regulation Among Women With Prior Gestational Diabetes: A Systematic Review.

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.

Expressed breast milk feeding practices in Hong Kong Chinese women: A descriptive study.

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.

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.

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.
