Adherence to two or more 24-h movement behavior guidelines reduces hypertension risk in adolescents
Adolescents who adhered to two or more movement behavior recommendations (physical activity, screen time, sleep) had a reduced risk of hypertension (RR=0.31; 95% CI: 0.09-0.98) compared to those meeting fewer guidelines. This association was not modified by social determinants of health.

Limitations
- ⚠The estimate for combined adherence is based on a small number of hypertension events, warranting cautious interpretation
- ⚠Movement behaviors were dichotomized using self-reported or parent-reported data, which may introduce measurement error
- ⚠The study is observational, so residual confounding cannot be ruled out
Frequently Asked Questions
What are the 24-hour movement behavior guidelines for adolescents?▼
The guidelines typically recommend at least 60 minutes of moderate-to-vigorous physical activity per day, no more than 2 hours of recreational screen time, and age-appropriate sleep duration (8-10 hours for adolescents).
Did meeting individual guidelines (e.g., only physical activity) reduce hypertension risk?▼
No. In adjusted models, meeting physical activity guidelines alone was not significantly associated with hypertension risk (RR=0.87; 95% CI: 0.42-4.17). Only adherence to two or more guidelines showed a significant protective effect.
How was hypertension defined in this study?▼
Hypertension was defined as systolic or diastolic blood pressure at or above the 95th percentile for age, sex, and height, based on standard pediatric guidelines.
Did social determinants of health affect the results?▼
No. Social determinants of health, measured by the Child Opportunity Index, did not modify the association between movement behavior adherence and hypertension risk.
