Dose–Response Relationship in a Healthy Habits Study for Head Start Preschoolers

Background Understanding the dose–response relationship in behavioral interventions is critical to guide future research efforts. However, only few studies have fully examined the dose–response relationship especially among children. Objective The aim of the study was to examine the relationships between level of participation and intervention effects. Methods The study used data from 39 Head Start parent–preschooler dyads participating in a 10-week lifestyle intervention.

Height, weight, waist circumference (WC), moderate-to-vigorous physical activity (MVPA), screen time, and fruit/vegetable intake were assessed.
