3.3 | Associated sleep factors for suicidal ideation of
subjects with asthma
Table 4 lists the adjusted OR for suicidal ideation according to sleep
parameters. After adjusting (model 1), the OR of sleep dissatisfaction
was 2.47 (95% CI, 2.39-2.56) times higher risk of suicidal ideation
than those with sleep satisfaction. In models 2 and 3, the ORs of sleep
dissatisfaction were 2.30 (95% CI, 2.22-2.38) and 1.21 (95% CI,
1.16-1.25), respectively. With regard to the average sleep duration,
when we defined the sleep reference as 7-8h, the OR of short sleep (≤5h)
was 1.80 (95% CI, 1.72-1.87) in model 1, 1.87 (95% CI, 1.79-1.95) in
model 2, and 1.37 (95% CI, 1.30-1.43) in model 3. Notably, long WCUS
was significantly associated with a decreased rate of suicidal ideation
among adolescents with asthma (OR: 0.84 [95% CI, 0.82-0.87] in
model 1, 0.86 [95% CI, 0.83-0.88] in model 2, and 0.88 [95% CI,
0.86-0.93] in model 3). The presence of asthma itself was also
significantly associated with suicidal ideation among adolescents with
asthma (1.31, 1.30, and 1.09).
