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.

Feasibility and Acceptability of an Online WhatsApp Support Group on Breastfeeding: Protocol for a Randomized Controlled Trial.

BACKGROUND: Mobile health, the use of mobile technology in delivering health care, has been found to be effective in changing health behaviors, including improving breastfeeding practices in postpartum women. With the widespread use of smartphones and instant messaging apps in Hong Kong, instant messaging groups could be a useful channel for delivering breastfeeding peer support. OBJECTIVE: The aim of this paper is to study the feasibility and acceptability of an online instant messaging peer support group by trained peer counselors on improving breastfeeding outcome in primiparous women in Hong Kong. METHODS: A two-arm, assessor-blind, randomized controlled feasibility study will be conducted on 40 primiparous women with the intention to breastfeed. Participants are recruited from the antenatal obstetrics and gynecology clinic of a public hospital in Hong Kong and randomly assigned at a 1:1 ratio to either intervention or control group. The intervention group receives peer support in an online instant messaging group with trained peer counselors on top of standard care, whereas the control group receives standard care. Breastfeeding outcome will be assessed for 6 months post partum or until weaned. The breastfeeding status, the proportion and duration of exclusive and any breastfeeding in each group, and the self-efficacy and attitude of participants will be assessed. The feasibility and acceptability of the study would also be assessed in preparation for a full randomized controlled trial. RESULTS: This study (protocol version 1 dated January 5, 2021) has been reviewed and approved by the institutional review board of the University of Hong Kong, Hospital Authority Hong Kong West Cluster (reference UW 21-039), on January 26, 2021. Data collection is ongoing and expected to be completed in December 2021. The findings will be updated on clinical trial registry and disseminated in peer-reviewed journals. CONCLUSIONS: This study aims to assess the feasibility and effectiveness of an online instant messaging peer support group in improving the breastfeeding outcome of primiparous women in Hong Kong. Its findings could inform the feasibility of a full-scale trial with this intervention design. TRIAL REGISTRATION: ClinicalTrials.gov NCT04826796; https://clinicaltrials.gov/ct2/show/NCT04826796.

Effect of a hospital policy of not accepting free infant formula on in-hospital formula supplementation rates and breast-feeding duration.

OBJECTIVE: To investigate the effect of public hospitals in Hong Kong not accepting free infant formula from manufacturers on in-hospital formula supplementation rates and breast-feeding duration. DESIGN: Prospective cohort study. SETTING: In-patient postnatal units of four public hospitals in Hong Kong. SUBJECTS: Two cohorts of breast-feeding mother-infant pairs (n 2560). Cohort 1 (n 1320) was recruited before implementation of the policy to stop accepting free infant formula and cohort 2 (n 1240) was recruited after policy implementation. Participants were followed prospectively for 12 months or until they stopped breast-feeding. RESULTS: The mean number of formula supplements given to infants in the first 24 h was 2·70 (sd 3·11) in cohort 1 and 1·17 (sd 1·94) in cohort 2 (P<0·001). The proportion of infants who were exclusively breast-fed during the hospital stay increased from 17·7 % in cohort 1 to 41·3 % in cohort 2 (P<0·001) and the risk of breast-feeding cessation was significantly lower in cohort 2 (hazard ratio=0·81; 95 % CI 0·73, 0·90). Participants who non-exclusively breast-fed during the hospital stay had a significantly higher risk of stopping any or exclusive breast-feeding. Higher levels of formula supplementation also increased the risk of breast-feeding cessation in a dose-response pattern. CONCLUSIONS: After implementation of a hospital policy to pay market price for infant formula, rates of in-hospital formula supplementation were reduced and the rates of in-hospital exclusive breast-feeding and breast-feeding duration increased.
