Sleep patterns of urban school going adolescents. Indian Pediatrics,
March, 45 : 183- 189.
Background: Sleep affects physical growth, behaviour and emotional
development besides determining cognitive functioning, learning and attention.
Sleep pattern is linked with the academic performance starting in adolescents.
Apart from physiological, psychological and environmental factors, socio-cultural
factors also play a major role in determining the sleep pattern of persons.
Objectives: To analyze the variance in sleep habits of adolescents of different
high school grades in urban India.
Methods: School going adolescents from grade ninth to twelfth of three schools
situated in Delhi were included in the study. About, 1973 school going
adolescents from all the four grades studying in the three schools were
included. Of these 53 did not provided the required information. Only 1920
adolescents submitted the required information.
Findings: Out of 1920 respondents 27.4 per cent adolescents were in ninth;
28.6 per cent in tenth and 19.8 per cent in eleventh grade, and 24.1 per cent in
twelfth grade; adolescents did not responded to the questions of which they
were not sure, resulting in missed responses; the frequency of missing
response was not more than two to three per cent for any of the variables
under study; average age of the sample was 15.1 years and total sleeping time
was 7.8 hours per day; most of the adolescents went to bed by 11:00pm;
(41.5%) took 23.6 minutes to fall asleep and used to wake up between 5:00am
to 6:00am; 42.6 per cent required 9.4 minutes to leave the bed after waking up;
most of the adolescents were not following this schedule on an average of 1.4
days a week; sleep efficiency of the sample was 92.6 per cent (+ 7.4),
refreshing sleep was reported by less than half of the sample; nocturnal
awakenings were reported by 37 per cent adolescents, average 3.3 hours after
getting the sleep; awakening were reported to be present since 2 (+ 1.9) years
with the frequency of 3.4 (+ 1.9) days a week, 1.6 (+ 0.8) times in a single night
besides spending 17.00 (+ 21.45) minutes per night being awake in bed; wake
up time was significantly different among groups, as school-going adolescents
from tenth and twelfth grades were early risers; missing day time nap did not
affect the day time functioning or the night time sleep in adolescents habituated
to daytime napping; gender was not found to influence the sleep parameters
among different grades.
