Abstract
The World Health Organization recommends breastfeeding until 6 months of age “to achieve optimal growth, development, and health.” Yet by five months of age only 42% of infants in Kenya are exclusively breastfed. In impoverished peri-urban communities, these rates may be much lower, with one study in Nairobi estimating a 2% rate EBF until 6 months. This study evaluates the impact of an interactive SMS intervention designed to provide information about breastfeeding and to assist women in addressing challenges that arise.

Primary Outcomes
Primary Outcomes (end points)
Our primary outcomes of interest are (1) women exclusively breastfeeding their babies, (2) women engaged in any breastfeeding at any point.
Primary Outcomes (explanation)
We measure this at 1, 4, and 6 months after birth.
Secondary Outcomes
Secondary Outcomes (end points)
We further explore engagement with the program, seeing whether the SMS intervention has differential effecs
Secondary Outcomes (explanation)
Experimental Design
Experimental Design
Women giving birth will be randomized into treatment or control. Women in the treatment group will receive both messages about breastfeeding and Jacaranda Health’s standard SMS package about postpartum care. Women in the control group will receive messages only from the standard postpartum care package.
Experimental Design Details
Randomization Method
Randomization is done by RapidPro, the platform that delivers the SMS intervention.
Randomization Unit
We randomize at the level of the individual mother.
Was the treatment clustered?
No
Experiment Characteristics
Sample size: planned number of clusters
The design is not clustered. We plan to enroll 5916 participants, of whom half will be contacted for follow up.
Sample size: planned number of observations
We plan to treat 5916 participants, half of whom will be contacted for follow up.
Sample size (or number of clusters) by treatment arms
The sample is split 50/50 to treatment and control.
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
