Father-involvement Telephone Support Intervention on Breastfeeding: RCT

Exclusive breastfeeding is recommended as the most beneficial form of infant nutrition during the first 6 months of life, which protects infants against childhood illness and reduces the risk of infant mortality and morbidity. The aim of this study is to implement and evaluate a breastfeeding telephone support intervention that involves mothers and fathers during the postpartum period. The objectives are to evaluate the effect of a father-involvement breastfeeding telephone support intervention on prevalence and duration of exclusive breastfeeding, postnatal depression and parent-infant bonding.

Hypothesis to be tested:

• Mothers who receive the father-involvement telephone support intervention will have a higher rate and a longer duration of exclusive breastfeeding at 1, 2, 4 and 6 months postpartum than those who receive the standard postpartum care.
• Mothers and fathers who receive the intervention will have: (a) fewer depressive symptoms, and (b) better parent-infant bonding at 2 and 6 months postpartum than those who receive the standard postpartum care.

Design and subjects: Randomized controlled trial. A sample of postpartum mothers (n = 738) and fathers (n = 738) will be randomly assigned to either the experimental or the control groups.

Study instruments: Edinburgh Postnatal Depression Scale (EPDS) and Postpartum Bonding Questionnaire (PBQ).

Intervention: The intervention consists of four weekly 20-30 minutes telephone-administered counselling sessions on breastfeeding, delivered individually in the first month postpartum for mothers and fathers.

Main outcome measures: The prevalence and duration of exclusive breastfeeding will be collected at 1, 2, 4 and 6 months postpartum. Postnatal depression and parent-infant boding will be assessed by the EPDS and the PBQ, respectively, at 2 and 6 months postpartum.

Data analysis: Generalized linear mixed models and survival analysis will be conducted to compare differences in the outcomes between two groups.

Potential application: The implementation of a simple, brief telephone-based intervention for breastfeeding families is most likely to be taken up in the primary health care setting. The results may better equip policy makers and health professionals to design health promotion programs for breastfeeding families, thus reducing the public health burden of childhood illness.
