Characteristics of study population.
| Characteristics | Patients | Sibling Controls | Significance | |
|---|---|---|---|---|
| Sex | Male | 38.5% | 51.9% | P = .1936 |
| (n = 20) | (n = 27) | |||
| Female | 61.5% | 48.1% | ||
| (n = 32) | (n = 25) | |||
| Body mass index | Nonobese | 48.1% | 80.4% | P = .0003 |
| (n = 22) | (n = 37) | |||
| Obese | 51.9% | 19.6% | ||
| (n = 24) | (n = 9) | |||
| Pubertal status | Prepubertal | 37.3% | 42.9% | P = .3657 |
| (n = 18) | (n = 21) | |||
| Postpubertal | 62.7% | 57.1% | ||
| (n= 30) | (n = 27) | |||
| Average age | Current age | 12.5 y | 12.2 y | P = .7063 |
| Subjective sleep assessment | No sleep problem | 47.9% | 76.5% | P = .0093 |
| (n = 23) | (n = 36) | |||
| Yes sleep problem | 52.1% | 23.5% | ||
| (n = 24) | (n = 11) | |||
Evidence was found of a difference in the percentages of obese vs nonobese as well as self-reported sleep problems in both controls and patients, but no differences were noted in sex, prepubertal vs postpubertal, or average age across controls and patients.
