Abstract
We test the effectiveness of a home-visit intervention to reduce the prevalence of iron deficiency anemia among children between 6 a 36 months of age in Sechura, a poor district located in northern Peru. Our sample consists of 47 peri-urban villages, which were randomly split into treatment and control in equal proportions. The World Food Programme conducted a home-visiting program in the treatment villages, which provided caregivers with information about locally available iron-rich foods and how to cook them to maximize their children's iron intake. During home visits, caregivers were also offered information about the importance of preventing anemia in young children, hygiene practices, feeding practices during illness periods, and responsive feeding. Our main outcome variables are the prevalence of anemia in children under 36 months of age, caregivers' knowledge about which local foods are rich in iron, their consumption patterns and cooking practices.

Interventions
Intervention(s)
The World Food Programme is implementing a home-visiting intervention to boost the consumption of iron-rich foods by vulnerable children between 6 and 36 months of age in Sechura, a poor district located in the region of Piura in Northern Peru.

Primary Outcomes
Primary Outcomes (end points)
Prevalence of iron deficiency anemia (hemoglobin concentration) and nutritional status (height and weight for age) of children under 36 months of age. All of these measured at the end of the program and 6 months after the program had ended.
Primary Outcomes (explanation)
Secondary Outcomes
Secondary Outcomes (end points)
Consumption of iron-rich foods (frequency, volume); responsive feeding practices; percentage of children with diarrhea; feeding practices during diarrhea episodes; knowledge about iron-rich foods; consumption of iron supplements.
Secondary Outcomes (explanation)
Experimental Design
Experimental Design
There are 47 peri-urban villages in Sechura, 23 of which were randomly selected for these visits. The remaining 24 villages are the control group.
Experimental Design Details
Not available
Randomization Method
Randomization done in office by a computer.
Randomization Unit
Peri-urban village ("asentamientos humanos")
Was the treatment clustered?
Yes
Experiment Characteristics
Sample size: planned number of clusters
47 villages
Sample size: planned number of observations
1,000 children
Sample size (or number of clusters) by treatment arms
23 villages in treatment, 24 villages in control.
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
We powered the study on our main outcome, the prevalence of anemia. With type-I error at 5%, type-II error at 20%, and with an ICC of 0.0375 (obtained from the DHS) the MDE is 0.2 standard deviations. All else equal, with an ICC of 0.09, the MDE is 0.25 standard deviations.
