1. Cross-sectional cohort analysis of 238 adolescents, ages 13-16.
2. Those with significant comorbidities were excluded: sleep apnea, narcolepsy, diabetes, sarcoidosis, CP.
3. Primary oucome was prehypertension (≥ 90th percentile for age, sex, and height), and secondary outcomes were elevated systolic BP & elevated diastolic BP.
4. Results revealed that adolescents with a sleep efficiency ≤ 85% were at a 3.5-fold increased odds of being prehypertensive or hypertensive. This association persisted after adjustment for sex, SES, and adiposity.
5. Short sleep duration was also associated with a 2.5-fold increase in the odds of prehypertension or hypertension. However, this association appears, in part, to be attributable to low sleep efficiency. This result was not statistically significant.
6. Limitations: sample size, sample bias, can only make an association (versus causality).
