Sažetak
Aim To evaluate how exposure to educational leaflet
about healthy sleep affects knowledge about sleep in adolescents.
Methods The study included students aged 15-18 years
from 12 high schools (1209 participants; 85% of eligible
study population). Multistage sampling was used and the
selected schools were randomly assigned into two intervention
groups and two control groups, according to the
Solomon experimental design. Intervention groups received
educational leaflets and control groups did not.
In one of the intervention groups and one of the control
groups, pre-testing of knowledge about sleep was performed.
Students answered the Sleep Knowledge Test,
which was constructed in accordance with the information
on the leaflet. Data were analyzed by four-way ANOVA
and additional analyses of simple main effects were performed.
Results Positive effect of educational leaflet was found
in students aged 15 (F = 28.46; P < 0.001), 16 (F = 5.74;
P = 0.017), and 17 (F = 17.17; P < 0.001), but there was no effect
in students aged 18 (P = 0.467). In male students, positive
effect of the leaflet was found only in the group that
had not been pre-tested (F = 6.29; P = 0.012), while in female
students, it was found in both pre-tested (F = 26.24;
P < 0.001) and not pre-tested group (F = 17.36; P < 0.001),
with greater effect in pre-tested group (F = 5.70; P = 0.017).
Female students generally showed better knowledge
about sleep than male students (F = 95.95; P < 0.001).
Conclusion Educational leaflets can be an effective first
step in educating younger high school students about
healthy sleep, with the method being more effective in female
adolescents.
