The prevalence of overweight, indicated by Body Mass Index (BMI 23-24.9 kg/m2), pre-obese (25-29.9 kg/m2) and obesity (>30 kg/m2) has increased in recent years. There has been a change in sleeping patterns(reduction in number of hours of sleep, quality of sleep, delay in onset of nighttime sleep) with the increasein BMI in Asian population, but studies are limited.Study included 230 college students from 18 to 24 years of which 171 were males. They were screened formajor diseases and psychological problems. Subjects having sleep disorders who are under medication wereexcluded. Sleep patterns, latency, duration, habitual sleep efficiency, sleep disturbances and daytimedysfunction were assessed using Pittsburgh Sleep Quality Index (PSQI).Association between PSQI components and BMI as per Asian criteria was assessed using Likelihood Ratio.Among all the studied 7 individual components, association of BMI code as per Asian criteria with sleeplatency and sleep disturbance component were significant (p<0.05). The awareness about sleep habits isneeded for good sleep quality.
