Association of sleep duration with blood glucose level of Gujarati Indian adolescents.

ABSTRACT

Recently studies conducted in various parts of the world indicate short sleep duration as a novel risk factor for development of type 2 diabetes. However, ethnic differences exist in the etiopathogenesis of diseases, the current study was undertaken to study the effect of sleep duration on the blood glucose level of Gujarati Indian adolescents. A randomized, non-experimental, cross-sectional study was done on the voluntary participants n=332 Gujarati adolescent boys and girls of age group 13-20 years studying at the schools and colleges in the Anand district. The participants were assessed for their sleep duration, body composition and blood glucose level. The sleep duration was reported by the subjects as the number of hours they slept on most of the nights in a week over the last one-year. The observations of the study were then analyzed after grouping them into 1) Adequate sleep duration at night, ASDN (≥7 hrs) and 2) Inadequate sleep duration at night, ISDN (<7 hrs) groups. One-way ANOVA and post hoc Tuky-Krammer test were used for finding significant differences (P<0.05) between groups. No significant difference was found in all parameters of body composition and fasting blood glucose level between the ASDN group and ISDN group in both boys and girls. However, gender difference exists in the body composition and blood glucose level. The current study indicates that inadequate sleep duration at night (<7 hrs) does not affect the blood glucose level of the Gujarati Indian adolescents of age group 13-20 years.
