Table 5. Adjusted odds ratios for associations of BMI and age with SDB at different RDI thresholds after stratification for HIV and HAART status*.
| N† | BMI (per kg/m2) | Age (per decade) | |
| HIV− (N = 60) | |||
| RDI ≥5 events/h | 52 | 1.18 (0.98, 1.43) | 1.95 (0.56, 6.72) |
| RDI ≥10 events/h | 41 | 1.32 (1.11, 1.57) | 2.05 (0.81, 5.18) |
| RDI ≥15 events/h | 35 | 1.43 (1.17, 1.75) | 2.08 (0.84, 5.16) |
| HIV+/HAART+ (N = 58) | |||
| RDI ≥5 events/h | 41 | 1.25 (1.04, 1.50) | 1.46 (0.61, 3.50) |
| RDI ≥10 events/h | 34 | 1.24 (1.05, 1.46) | 1.05 (0.47, 2.32) |
| RDI ≥15 events/h | 28 | 1.30 (1.09, 1.54) | 2.15 (0.91, 5.09) |
| HIV+/HAART− (N = 41) | |||
| RDI ≥5 events/h | 30 | 0.93 (0.77, 1.13) | 2.06 (0.76, 5.54) |
| RDI ≥10 events/h | 22 | 0.92 (0.78, 1.10) | 2.72 (1.04, 7.15) |
| RDI ≥15 events/h | 18 | 0.94 (0.79, 1.11) | 2.05 (0.85, 4.94) |
*Adjusted for race.
†
N, number of participants with SDB at the specified cutpoint.
RDI, respiratory disturbance index.
RDI is defined as the number of apneas and hypopneas (a ≥3% desaturation or an arousal) per hour of sleep.
Odds ratio and confidence intervals in bold represent observations that were statistically significant.
Note: When HIV+ men were combined into one group (N = 99), ORs for BMI and age were attenuated and of borderline significance. For example, for an RDI ≥5 events/h, BMI had OR: 1.10 [95% CI:0.97–1.25]] and age had OR 1.05 [95% CI: 0.99–1.12. Similar findings were observed for an RDI ≥10 and ≥15 events/h (data not shown).
