Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

During Chinese mothers' doing the month, they are often housebound and find it difficult to attend group support or seek help during the first month postpartum which is the critical period in sustaining exclusive breastfeeding and at high risk of weaning. This can adversely affect their general well-being, and are associated with stress, anxiety and postnatal depression. Thus, mothers have expressed the need for real-time, real world, personalized support that allow them to get immediate breastfeeding support, helps in overcoming the challenges and subsequently improve exclusive breastfeeding. The aim of the proposed study is to assess the effectiveness of an ecological momentary intervention (EMI)-based breastfeeding intervention in improving exclusive breastfeeding outcomes and to inform clinical practice and services for breastfeeding mothers in Hong Kong. Such interventions have been considered as a rising shift from traditional model of care towards an e-technology based health model that may improve exclusive breastfeeding duration globally.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

It is well recognised that breastfeeding is extremely beneficial for child survival, growth, and maternal health and is one of the most effective health interventions for preventing infant and child mortality and promoting lifelong maternal health. In addition, breastfeeding provides significant economic benefits and improves health equity in society. In Hong Kong, data from 2021 shows only 22% of women exclusively breastfeed until six months postpartum, significantly less than both the average global rate of 38% and the World Health Organization (WHO) 2025 target of 50%. Some of the common reasons cited by mothers for early weaning relate to breastfeeding problems that are easily avoided with appropriate early professional support, such as perceived insufficient milk, poor latching and sore breasts. Timely breastfeeding support could therefore promote exclusive breastfeeding. However, such support is often inadequate and has been difficult to obtain during the recent COVID-19 pandemic. In addition, mothers in Hong Kong may find it difficult to leave home during the early postpartum period due to the overwhelming workload and the cultural tradition practice of 'doing the month' in which women remain housebound during the first month postpartum. Therefore, it is be important to provide adequate support to mothers in Hong Kong to ensure that breastfeeding can continue for the optimal duration, thereby providing life-long protection for both mother and infant.

Social cognitive theory (SCT) is widely used to analyse behavioural changes in breastfeeding in response to technology-guided interventions. We will use SCT as a theoretical framework to guide the development of a message library and the delivery of both regular and chat-style support messages. The increased accessibility of an Internet-delivered intervention provides a way to promote each mother's sense of agency by enabling them to access the support they require when they need it. As more people turn to eHealth, the development of an Internet-delivered SCT-based intervention (iSCT-I) to support and educate women may provide a cost-effective way to increase breastfeeding rates. Moreover, the WHO has concluded that will not be possible to reach universal health care coverage without investing in, and broadly adopting, eHealth. EMI is a cost-effective intervention framework that allows personalisation of both the content and delivery method, it can therefore provide a practical and effective strategy for delivering iSCT-I for improving breastfeeding duration and uptake. However, there have been no previous studies of EMI-based breastfeeding interventions. Therefore, we propose an RCT to evaluate the effectiveness of EMI-delivered iSCT-I; a real-time, personalized, and cost-effective approach for improving exclusive breastfeeding rates.

This multi-center randomized control trial adopts two arm design to examine and compare the effects between ecological momentary intervention and usual care to improve breastfeeding outcomes. The study hypotheses are (1) Primiparous mothers who receive an EMI-based breastfeeding intervention will significantly increase their exclusive breastfeeding intention and duration, and (2) The intervention group will have a higher breastfeeding self-efficacy score (BSES) and breastfeeding knowledge and attitude scores at three months postpartum.

A pilot study will be conducted. Aiming to recruit 20 participants. (10:Intervention; 10 Control)

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

EMI intervention group

Participants in the intervention group will receive instant messaging (i.e., an EMI delivery platform). Our multidisciplinary team, including an obstetrician, midwife, lactation consultant, biostatistician, and social psychologist, will develop a message library and protocol for EMI delivery.

Group Type EXPERIMENTAL

Regular messages

Intervention Type BEHAVIORAL

The EMI-I messages will be delivered in sequence over three months. The content, frequency, and timing of the messages will be determined by participant preferences, as determined during the baseline evaluation, as personalisation is central to such cognitive and behavioural changes. The messages will mainly be text-based, but other forms such as videos will also be used, depending on the needs of the participants.

Nurse-led real-time support messages (chat type)

Intervention Type BEHAVIORAL

The nurse will initiate 10-15-minute chats via an online platform (e.g., WhatsApp) after all instant messages for each session have been delivered. The nurse will guide the participants to set goals for breastfeeding. Any anticipated barriers will be discussed. The participants can also initiate the chats. While there is no limit to the number of chat messages, nurse-led real-time support messages will be provided during working hours (i.e., 9 am-6 pm on weekdays).

Control group

Participants in the control group will receive text messages containing general information on breastfeeding from the Hospital Authority, which is open to the public and includes reminder text messages of important follow-up surveys. Messages will not be personalised, and nurse-led real-time support messages will not be available.
