Table 1.
Demographics and comorbidities in patients without previous OSA diagnosis who were referred to the sleep lab (n = 392).
| Demographics | All (n = 392) | AHI ≥ 5 events/h (n = 299) | AHI < 5 events/h (n = 93) |
|---|---|---|---|
| Age, mean (SD) | 51 (16) | 52 (15) | 45 (17) |
| Male, n (%) | 196 (50%) | 164 (55%) | 32 (34%) |
| BMI, mean (SD) | 34 (8) | 35 (8) | 32 (7) |
| Comorbidities | All (n = 392) | AHI ≥ 5 events/h (n = 299) | AHI < 5 events/h (n = 93) |
| HTN | 215 (55%) | 173 (58%) | 42 (45%) |
| CHF | 25 (6%) | 21 (7%) | 4 (4%) |
| COPD | 41 (10%) | 29 (10%) | 12 (13%) |
| Chronic pain | 27 (7%) | 23 (8%) | 4 (4%) |
| DM | 90 (23%) | 81 (27%) | 9 (10%) |
| Asthma | 50 (13%) | 37 (12%) | 13 (14%) |
| CVA | 19 (5%) | 16 (5%) | 3 (3%) |
| Afib | 25 (6%) | 23 (8%) | 2 (2%) |
Significant number of positive obstructive sleep apnea patients are associated with male predominance, diabetes mellitus, atrial fibrillation, chronic pain, and hypertension. Afib = atrial fibrillation, AHI = apnea-hypopnea index, BMI = body mass index, CHF = congestive heart failure, COPD = chronic obstructive pulmonary disease, CVA = cerebrovascular accident, DM = type 2 diabetes mellitus, HTN = hypertension, OSA = obstructive sleep apnea, SD = standard deviation.
