Healthy Habits During and After Gestational Diabetes (VALID III)

2026년 7월 20일 업데이트: Thanh Duc Nguyen, Thai Binh University of Medicine and Pharmacy

Healthy Habits During and After Gestational Diabetes: A Cluster Randomised Family Intervention Controlled Trial in Northern Vietnam (VALID III)

Gestational diabetes mellitus (GDM) is associated with an increased risk of childhood obesity and other adverse health outcomes. Early-life nutrition, particularly exclusive breastfeeding, plays an important role in reducing this risk. In Vietnam, infant feeding and childcare practices are strongly influenced by family members, including husbands, grandparents, and parents-in-law.

The Healthy Habits During and After Gestational Diabetes (VALID III) trial aims to evaluate the effect of a co-created family-based health intervention on improving infant feeding practices and childhood body composition among children born to women with GDM. The intervention includes counseling, peer support, digital health components, educational materials, and follow-up support for nutrition, infant feeding practices, physical activity, and GDM management from pregnancy through 24 months after birth. Participants in the control group will receive standard care together with access to a GDM management website.

The primary objective is to evaluate the effect of the intervention on the duration of exclusive breastfeeding during the first 180 days after birth. Secondary objectives include evaluating exclusive breastfeeding at 6 months, child fat mass index at 24 months, and broader maternal and child health and wellbeing outcomes.

상세 설명

Background

Childhood obesity is a major global health burden, with increasing prevalence in many Asian countries, including Vietnam. However, health policies and programs in low- and middle-income countries (LMICs) often rely on evidence generated in settings that may not be directly applicable, limiting the effectiveness of interventions. Exposure to gestational diabetes mellitus (GDM) is associated with an increased risk of childhood obesity, while optimal early-life nutrition, particularly exclusive breastfeeding, may reduce this risk. In Vietnam, family members, including husbands, grandparents, and parents-in-law, have a substantial influence on infant feeding and childcare practices. These contextual factors highlight the need for family-based interventions to support healthy maternal and child behaviors following a pregnancy complicated by GDM.

Objectives

The Healthy Habits During and After Gestational Diabetes (VALID III) trial aims to evaluate the effect of the "Healthy Habits" family-based health intervention on improving infant feeding practices and childhood body composition among children born to women with GDM. The study will also assess the broader effects of the intervention on maternal and child health and wellbeing.

Study Design

This is a two-arm, parallel-group, superiority cluster randomised controlled trial with a 1:1 allocation of communes to either the intervention group (standard care plus the "Healthy Habits" intervention) or the control group (standard care plus access to a GDM management website). Pregnant women diagnosed with GDM between 24 and 28 weeks of gestation and their families will be recruited. Participants will be followed from pregnancy until 24 months after birth.

Intervention

The "Healthy Habits" intervention is a co-created family-based program delivered during pregnancy and continuing until 24 months postpartum. It includes counseling, peer support, digital health components, educational materials, and follow-up support focused on nutrition, infant feeding practices, physical activity, and GDM management, alongside routine clinical care.

Outcome Assessment

The primary outcome is the duration of exclusive breastfeeding during the first 180 days after birth. Secondary outcomes include the proportion of infants exclusively breastfed at 6 months, child fat mass index at 24 months after birth, process outcomes, and broader maternal and child health and wellbeing outcomes.

실험적: Healthy Habits
A co-created intervention delivered during pregnancy and up to two years after birth that includes counselling, peer support, digital health elements, educational materials, and follow-up support on nutrition, infant feeding practices, physical activity, and GDM management provided according to routine clinical practice in the Hung Yen province, Vietnam
행동: Hybrid intervention

The VALID III "Healthy Habits" intervention is a culturally tailored, gender-sensitive, intergenerational complex intervention for women with gestational diabetes mellitus (GDM), delivered from diagnosis to 24 months postpartum. It differs from standard care through its extended duration and integrated family- and digital-based approach.

It includes five components: (1) nutrition and infant feeding support (diet, breastfeeding, complementary feeding, household practices); (2) physical activity guidance for pregnancy/postpartum and family active play; (3) intergenerational family engagement involving partners and grandparents; (4) self-care and GDM management including diet advice, blood glucose monitoring, and free clinic testing; and (5) digital support via messaging and educational content.

Compared with usual care, the intervention integrates co-created materials, family involvement, and continuous digital engagement to support sustained behavioural change
활성 비교기: Standard Care + Web Access
Access to a website with GDM management + standard care
행동: Standard Care with Passive Web Access
Participants in this control group receive standard care for GDM according to routine clinical practice in Vietnam (antenatal care, dietary advice, glucose monitoring). In addition, they are provided with a website link (https://www.babaukhoemanh.com/en) for passive access to basic GDM management guidance. They do not receive any proactive messaging, peer support, or family engagement

기간
Duration of exclusive breastfeeding
기간: Day 1-180 after birth
Exclusive breastfeeding is defined as feeding with no other food or drink, except prescribed medicines, oral rehydration solution, vitamins, and minerals, following the first week of birth. Measured as a continuous variable representing the total number of days each infant was exclusively breastfed during the first 6 months of life. Data will be prospectively recorded by mothers on a weekly basis using a structured hard-copy Infant Feeding Diary kept at home. Research assistants will verify the diaries and capture content in photographs during home visits at 3 and 6 months after birth
