Childcare Correlates of Physical Activity, Sedentary Behavior, and Adiposity in Preschool Children: A Cross-Sectional Analysis of the SPLASHY Study

الملخص EN

Background.

The childcare (CC) environment can influence young children’s physical activity (PA), sedentary behavior (SB), and adiposity.

The aim of the study was to identify a broad range of CC correlates of PA, SB, and adiposity in a large sample of preschoolers.

Methods.

476 preschool children (mean age 3.9 yrs; 47% girls) participated in the Swiss Preschoolers’ Health Study (SPLASHY).

PA and SB were measured by accelerometry.

Outcome measures included total PA (TPA), moderate-to-vigorous PA (MVPA), SB, body mass index (BMI), and skinfold thickness (SF).

PA measures consisted of both daily PA during CC attendance days and overall daily PA (CC and non-CC days).

Results.

We identified the following CC correlates for higher TPA and/or higher MVPA or lower SB during CC attendance days: older age, sex (boys), more frequent child-initiated interactions during CC, mixing different ages within a group, and the presence of a written PA policy in the CC (all p≤0.02).

The CC correlates for overall TPA and/or MVPA or lower overall SB including both CC and non-CC days were the following: older age, sex (boys), more frequent child-initiated interactions during CC, mixing different ages within a group, less parental PA involvement in the CC, and having a larger surface area in CC (all p≤0.046).

Correlates for lower SF were sex (boys) and parental PA involvement in the CC (all p≤0.02), and, for lower BMI, only increased age (p=0.001) was a correlate.

Conclusions.

More frequent child-initiated interactions and mixing different ages in CC, the presence of a written PA policy, and a larger CC surface are correlates of PA and SB during CC attendance days and/or of overall PA.

Parental involvement in CC PA projects was a correlate for reduced body fat.

These novel factors are mostly modifiable and can be tackled/addressed in future interventions.
