Contributing Factors to Day Time Sleepiness among Secondary School Students in Ibadan
Journal Title: Journal of Advances in Medicine and Medical Research - Year 2016, Vol 13, Issue 1
Abstract
Aims: Narrowing of the upper airway during sleep causes snoring, hypoventilation and decreased oxygenation of the brain with recurrent arousal from sleep and a cascade of excessive daytime sleepiness, poor concentration in class and undesirable academic performance. This study determined the prevalence of day time sleepiness among students in secondary schools in Ibadan and establishes its association with body mass index, tonsil size, Mallampati score, and academic performance. Study Design: A prospective, cross sectional community based study. Place and Duration of Study: Ibadan town, Nigeria between August 2013 and July 2014. Methodology: This school-based cross-sectional study recruited the students by systematic random sampling technique. The participants answered an interviewer assisted structured questionnaire and had clinical examination for structural abnormalities of the oropharynx, Mallampati score, tonsillar grade and the BMI. The academic performances were determined using the overall mean average score of all the subjects offered during the first and second term of the academic session. The test of association between daytime sleepiness and other variables were determined. Statistical analysis of the data was done with Statistical Package for Social Sciences (SPSS) version 16. Results: There were 493 participants consisting 262 (53.1%) males and 231(46.9%) females (M: F ratio of 1.1:1), the mean age was 12.6 years + 2.6 (range = 9-17 years) and the mean BMI was 22.60 kg/m2±3.0 (range= 15.7 - 35.2 kg/m2). Daytime sleepiness was encountered in 56 (11.4%) of the students, this was association with high Mallampati score (p < 0.001), high BMI (p < 0.001), but had no association with academic performance (p = 0.54), tonsillar enlargement (p = 0.35), gender (0.82) and overnight sleeping duration (p = 0.21). Conclusion: The prevalence of daytime sleepiness among the secondary school students was 11.4%, and had no associated with academic performance. High BMI and Mallampati score were the significant risk factors identified.
