Efficacy of Center-based Childcare to Mitigate Unhealthy Weight Gain in Preschoolers From Low-income Households During the Summer

Обзор

Studies show that preschool-age children are especially vulnerable to accelerated weight gain during the summer, with those from low-income households (≤185% poverty level or Medicaid eligible - the target population for this study) exhibiting the greatest risk of unhealthy weight gain. Despite numerous interventions designed to prevent OWOB, none target preschoolers during summer. For families from low-income households, attending center-based childcare is associated with a lower risk of developing OWOB by 1st grade compared to attending home-based care. Center-based childcare lowers the risk of OWOB through daily rules/routines that promote healthy behaviors. For families from low-income households, publicly funded center-based childcares (e.g., needs-based pre-K, Head Start) typically operate on an academic/school 9-month calendar (Aug-May). During summer, fewer than 30% of preschoolers attend center-based childcare. For many preschoolers from lower-income households, summer may serve as an extended period away from formal center-based childcare, because the out-of-pocket expense may prohibit attendance. This may promote unhealthy behaviors and excessive weight gain. In the majority of US states, publicly funded center-based childcare during the academic/school year for families from underserved populations is free; however, center-based childcare during the summer is an out-of-pocket expense for many of these families. Despite parents' desire for childcare during the summer, a major reason children from low-income households do not attend center-based care during summer is cost. This creates unequal access to resources and likely exacerbates health disparities for families from low-income households. Using a structural intervention approach, this study will test the impact of providing free center-based childcare in the summer. This R01 will rigorously test the impact of providing free center-based childcare during the summer on weight status of preschoolers from low-income households (≤185% of poverty level or Medicaid eligible).

Вмешательства

• Поведенческое Childcare
  Daily Schedule: The daily schedule will be from \~8am to 5pm M-F. The centers will provide lunch, snacks, and a nap. The activities each day will focus on core state curriculum standards for reading, social emotional learning, and kindergarten readiness. Preschoolers will be offered 2-3 15-20min recess periods each day and be provided physical education for 45min on a rotating 2/3 schedule every 2 weeks (i.e., 2 days/week followed by 3 days/week). Meals: All meals provided will be reimbursed thr
