- Comparing mean body mass index between various groups (n=1724) of sleep duration (one-way analysis of variance).
| Sleep duration | n (%) | Mean BMI | P-values |
|---|---|---|---|
| Shorts sleepers (group1) | 393 (22.7) | 24.2±6.5 | 0.001* |
| Normal sleepers (group2) | 959 (55.6) | 23.03±5.5 | |
| Long sleepers (group3) | 372 (21.6) | 23.2±5.7 | |
