Lifestyle interventions improve 24-hour movement behaviors in preschool children
Lifestyle interventions were associated with increases in moderate-to-vigorous physical activity (MD 5.77 min/day) and sleep duration (MD 0.18 h/day), and reductions in sedentary behavior (MD -7.62 min/day) and screen time (MD -0.33 h/day) in preschool children aged 2-6 years. However, heterogeneity was substantial and the certainty of evidence was low.

The Claim
Lifestyle interventions improve 24-hour movement behaviors in preschool children
This conclusion is most relevant to: Preschool children aged 2-6 years (13,659 participants from 43 trials across 16 countries).
How It Works
The proposed biological pathway:
- ▸Lifestyle interventions promote structured physical activity opportunities
- ▸Behavioral counseling reduces screen time and sedentary behavior
- ▸Sleep hygiene education improves sleep duration
- ▸Result: Modest improvements in multiple movement behaviors
Who Might Benefit
Evidence fit by population:
- ▸Preschool children aged 2-6 years (13,659 participants from 43 trials across 16 countries)
Recommended Dose
N/A
Limitations & Caveats
Important context when interpreting this evidence:
- ▸High heterogeneity across outcomes (I² 63-95%)
- ▸Low certainty of evidence (GRADE)
- ▸Small-study effects could not be ruled out for screen time
