Table 1.
Descriptive statistics of the weighted sample, grouped by age category, from the NDNS Years 1–8.
Fig 1.
The unadjusted relationship between sleep and age, across all age groups (95% CI shown in grey).
Table 2.
Cross-sectional associations between sleep duration and metabolic risk score, presenting coefficients for both the quadratic sleep duration term and the linear sleep duration term from the regression model.
Fig 2.
Model predictions of metabolic risk score.
Model predictions of metabolic risk score (with 95% confidence intervals) as sleep durations vary above and below the mean (model 3, all age groups).
Fig 3.
Model predictions of metabolic risk score by age group.
Model predictions of metabolic risk score (with 95% confidence intervals) as sleep durations vary above and below the mean, separated by age group (model 3, A: age 11 to 18 years, B: 19 to 35 years, C: 36 to 50 years, D: 51 to 70 years).
Table 3.
Cross-sectional associations between the difference between weekend and weekday night sleep and metabolic risk score.
