Background:Lack of adequate sleep, typically defined as less than 6 hours per night, has been linked to an increased risk of insulin resistance and impaired glucose metabolism. The present study was conducted to assess the effect of sleep duration on the blood glucose level. Materials & Methods:100 subjects age ranged 14-20 years of both genders were classified as adequate sleep duration at night (ASDN) and inadequate sleep duration at night (ISDN). Data such as name, age, gender etc. was recorded. Waist circumference (WC), Hip circumference (HC), Waist – Hip Ratio (WHR), body fat percentage (BF %), total body fat mass (FM), fat free mass (FFM), fat mass index (FMI) was calculated. Results: Age group 14-15 years had 9 boys and 8 girls, 16-17 years had 9 boys and 11 girls and 18-20 years had 12 boys and 11 girls. In ASDN and ISDN boys and ASDN and ISDN girls, mean weight (kgs) was 48.9, 54.3, 43.6, and 43.8, BMI was 18.7, 19.9, 18.2 and 18.7, BF% was 17.2, 19.3, 22.4 and 23.0, FM was 10.1, 10.6, 10.2 and 10.8, FMI was 3.8, 4.9, 4.5 and 4.7, FFM was 40.2, 42.5, 33.2, and 34.1, FFMI was 14.7, 15.8, 14.8, and 15.2, WC was 65.2, 66.1, 62.4, and 48.6, HC was 81.7, 82.5, 79.4, and 78.4, WHR was 0.85, 0.80, 0.79, and 0.78 and FBS was 84.2, 83.2, 84.0, and 83.2 respectively. The difference was significant (P< 0.05). Conclusion: Subjects in the 14–20 age range do not have a blood glucose level that is impacted by short sleep duration (less than 7 hours). This is most likely due to the fact that sleep deprivation has no effect on body composition.
