Summary

The investigators developed a home-based growth chart that offers a simple and inexpensive way for caregivers to have access to simple health and nutrition information guided by behavioural economics analysis as well as to track their child's linear growth, empowering them to act to improve their child's nutrition. Results from a pilot study conducted in rural Zambia suggest that growth charts installed in homes can increase awareness and reduce early-life growth deficits, particularly among children experiencing growth faltering. The main objective of this study is to assess the impact and cost-effectiveness of growth charts through a cluster-randomized trial in Indonesia. The primary outcome is child height-for-age z-score.

Detailed description

The study is divided into two phases. In the first phase, growth chart development activities will be conducted in two villages in each of Manggarai Timur and Trenggalek districts to ensure the chart design is compatible with the local context and chart information is understandable to caregivers. Focus group discussions (FGDs), key informant interviews (KIIs), and door-to-door user testing will be conducted in each village. Results from the FGDs and KIIs will inform a draft growth chart design that will then be user tested in 10 households in each village. Qualitative interviews will be conducted with each household approximately two weeks after chart installation to gather insights on the usability of the growth chart. The chart design will then be finalized for use in the second phase of the study. In the second phase, 1,480 caregiver-child dyads will be recruited and enrolled in the study as part of a baseline survey. Dyads will be sampled using a two-stage procedure. 110 villages will be selected proportionate to national census population size. All sub-villages ("dusun") within selected villages will be randomly assigned into two groups: 1) Growth chart; and 2) Control. Eligible caregiver-child dyads with children between 9 and 14 months will be selected from each sub-village.

Conditions

• Child Growth

Interventions

Type	Name	Description
OTHER	Home-based growth charts	The growth chart contains simple information of nutritious food, health, and sanitation information at the top and height chart is located at the bottom where caregivers can measure their child's linear growth. Growth charts will be installed in intervention group homes just after the baseline survey.
OTHER	Home visits for baseline surveys	Households will be visited for baseline surveys.
OTHER	Home visits for end line surveys	Households will be revisited after 1 year of grace-period for baseline end line surveys.
OTHER	Measurement of child's height-for-age and weight-for-age	The child's height-for-age and weight-for-age will be measured for participating dyads at the time of the baseline and end line surveys.
