Experimental Design (Public)
|
Before
This is a parallel two-arm cluster-randomized controlled trial.
A total of 1,420 caregiver-child dyads will be recruited and enrolled in the study. There are two participant inclusion criteria: 1) the child must be 9-14 months old at enrollment; and 2) the caregiver must be above 18 years old at enrollment. Study dyads will be randomly assigned at the level of dusun (a sub-village administrative unit in Indonesia) to one of two groups: 1) growth charts; and 2) pure control. Data will collected during a baseline survey administered at the time of enrollment and at an endline survey administered at the end of a 12-month intervention period.

A total of 1,480 caregiver-child dyads will be recruited and enrolled in the study.

Power calculation: Minimum Detectable Effect Size for Main Outcomes
|
Before
The study is powered at 80 percent to detect a 0.19 SD improvement in HAZ over the 12-month intervention period, assuming α=0.05, a follow-up rate of 80 percent (attrition of 20 percent, or 1 of 5 enrollees per dusun), and an intra-class correlation coefficient (ICC) of 0.10.
