3.2 | Sleep parameters among adolescents with and
without asthma
Table 3 shows the differences of sleep parameters between the asthma
groups and non-asthma groups. Adolescents with asthma were significantly
different from those without asthma in terms of every sleep variable.
Most of all, sleep satisfaction was significantly poorer (sleep
satisfaction not enough: 44.6% vs. 42.6%) in the asthma group than it
was in the non-asthma group. Adolescents with asthma slept less than did
those without asthma (average sleep duration 6.59 ± 0.94 vs 7.29 ± 1.45
hr, proportion of less than 5 hr of sleep duration was 8.6% vs 7.6%,
respectively, p < 0.001). Asthmatics were also more likely to
be night owls on both weekdays (22.6% vs 21.2%) and weekends (41.8%
vs 41.2%), and to be early larks on weekdays (42.4% vs 42.0%), while
less likely to be on weekends (4.0% vs 6.3%). The weekday sleep
duration (5.58 ± 1.81 vs 6.92 ± 1.43 hr) was shorter, while the weekend
sleep duration (9.11 ± 2.75 vs 8.21 ± 2.91 hr) was significantly longer
in adolescents with asthma than it was in those without. In addition,
the WCUS duration was significantly longer in the adolescents with
asthma than it was in those without asthma (3.13 ± 0.01 vs 2.29 ± 0.01
hr). The proportion of longer WCUS among adolescents with asthma was
48.9%, and that among adolescents without asthma was 43.3%.
