Abstract
To determine the prevalence of sleep patterns and their relationship with academic performance among adolescents. The analytical cross-sectional study was conducted from March to August 2015 in Gulshan Town of Karachi and comprised students in grades 6 to 8 who were selected from six government and private schools. Data was collected regarding their sleeping time, wake-up time, sleep latency and total sleep duration. Paediatric Daytime Sleepiness Scale was administered to calculate daytime sleepiness. Academic performance of students was taken from school academic records. Data was analysed using SPSS 22. Of the 440 subjects, 234 (53.2%) were boys and 206 (46.8%) were girls. The overall age range was 11-16 years. A total of 280 (63.6%) students had abnormal sleep patterns, 182(41.4%) suffered from daytime sleepiness, 41 (9.3%) had abnormal sleep latency and 201 (45.7%) scored below 60% in their exams. Among poor sleepers, 157 (56.1%) scored below 60% in their exams. More than half the subjects were found to be sleeping less than required, which eventually affected their academic performance.
Highlights
Sleep is a basic human need and is considered an important indicator for health and good quality of life at all ages
Sleep pattern varies throughout our lives, with most important changes occurring during the initial years as well as during the transition phase from childhood to adolescence
After approval from the ethics review committee of Aga Khan University Hospital (AKUH), Karachi, the sample size was calculated using World Health Organisation (WHO) calculator on the basis of least proportion of poor sleep patterns obtained from literature.[14]
Summary
Sleep is a basic human need and is considered an important indicator for health and good quality of life at all ages. Several factors can affect the quality of sleep such as work, lifestyle, environment, health and stress It is defined as a vital component of physical growth and enhancement of the academic performance.[1] Sleep pattern varies throughout our lives, with most important changes occurring during the initial years as well as during the transition phase from childhood to adolescence. Such changes are partly the result of complex changes that occur in the circadian system and brain maturation. The current study was planned to determine the prevalence of sleep patterns among adolescents and its relation with academic performance
