There is only one study group (the immediate intervention group). In this group, the child’s health will be evaluated, the home environmental health will be assessed and reported to the family, and the family will receive in-home education. Within 60 days of the in-home education, a series of interim controls for the home will be provided by HHN using a specific set of standard interventions and a site-specific set of targeted interventions based on the assessment findings. The home will be checked to ensure the interventions were properly done. After 6 months, the child’s health will be reevaluated and the environmental health of the home will be assessed a second time to evaluate the impact on the child’s health.
