Among young adolescents, longer sleep duration and higher sleep efficiency were associated with a more favorable cardiometabolic profile, independent of other obesity-related behaviors, a new study found. The cross-sectional study of 829 adolescents (51.5% girls, mean age 13.2 years) derived sleep duration, efficiency, and moderate-to-vigorous physical activity from >5 days of wrist actigraphy recording for >10 hours/day. The primary outcome was a metabolic risk score; secondary outcomes include score components and dual-energy radiograph absorptiometry fat mass. Among the details:
- Median sleep duration was 441.1 (54.8) minutes per day and sleep efficiency was 84.0%.
- Longer sleep duration was associated with lower metabolic risk scores.
- Associations with sleep efficiency persisted after adjustment for BMI z score and physical activity, television-viewing, and diet quality.
- Longer sleep duration and greater sleep efficiency were also favorably associated with waist circumference, systolic blood pressure, high-density lipoprotein cholesterol, and fat mass.
