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

10. juni 2026 oppdatert av: Michael Beets, University of South Carolina
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).

Våpen og intervensjoner

Deltakergruppe / Arm
Intervensjon / Behandling
Eksperimentell: Intervention
Children randomly assigned to receive free center-based childcare during the summer will be provided 8 to 10 weeks (depending on the length of summer - which can vary due to school-year closures and make-up days) of access to a school-operated, needs-based center-based childcare during the summer.
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 through the district's Summer Food Service Program and will adhere to the nutritional guidelines of the Summer Food Service Program. The program will be overseen by district personnel who are responsible for pre-K during the 9m school year. Staffing: The program will be staffed by pre-K teachers who teach in the district. Teachers have already expressed interest in staffing the summer program and will be recruited by organization personnel. Setting: The center-based childcare wil
Ingen inngripen: Control
The control group will not receive free access to attend the center-based childcare during the summer.

Tidsramme
Bioelectrical Impedance
Tidsramme: Baseline (0 months) prior to the beginning of summer and post intervention at the end of summer (3 months)
Bioelectrical Impedance (BIA) will be used as a measure of children's body composition. This will allow for the quantification of whole-body fat mass and fat free mass associated with changes over school and summer. BIA will be collected via the Inbody 270 (Seoul, South Korea), which is validated for use in 3-4 yr-old children.
