Table 5.

Simple score for screening for obstructive sleep apnea utilizing variables commonly available in IBD clinic—obesity (2 points), current smoking (1 point), age over 45 (1 point), and clinically active IBD (1 point).

Variables	Score, if present
Obesity	2
Currently smoking	1
Age over 45	1
Clinically active IBD	1

The area under the receiver-operating curve for moderate–high risk of obstructive sleep apnea (OSA-50 > 5) was 0.77 (0.73–0.81), with Youden’s index of 1.46. A score of >2 had a sensitivity of 89% and a specificity of 56%. Obesity is defined as body mass index greater than 30, clinically active IBD refers to a Harvey–Bradshaw Index of >5 or a Simple Clinical Colitis Activity Index of >2.

Abbreviations: IBD, inflammatory bowel disease; OSA, obstructive sleep apnea
