INTRODUCTION: Sleep is a physiological process which is required for good physical, mental and social well being (Beebe, 2011). A good sleep is essential to maintain body’s circadian rhythm. Sleep deprivation can disrupts body’s homeostasis leading to various ill effects like heart disease, diabetes, depression, accidents, impaired cognition, and a poor life quality. In recent days, lifestyle modifications have increased the prevalence of sleep disturbances especially among adolescents. As adolescence is the vital transitional phase where an individual have to determine their future both personal and professionally, any disturbance in sleep would affect their health and also would affect their academic performance. So the current study focused to assess sleep hygiene among school going adolescents. AIM & OBJECTIVE: To assess the sleep hygiene and pattern among going adolescents. To analyse the risk factors of compromised sleep hygiene and pattern among going adolescents METHODOLOGY: This cross sectional study analysed the sleep pattern among school going adolescents (n=278) using Pittsburgh Sleep Quality Index (PSQI) which differentiates poor (Global PSQI Score >5) from good (Global PSQI Score <5) sleep by measuring seven domains. Then the Sleep Hygiene among these adolescents was analysed using 13 item Sleep Hygiene Index Inventory tool. RESULTS: The current study shows that the prevalence of sleep deprivation among the study participants were 52.17% and the average sum of global PSQI score was above 5 indicating poor sleep index. There was a positive correlation (R2 = 0.2535) between poor sleep hygiene and Global Sleep quality index. Also we found that participants with higher caffeine intake, stress, Inconsistent bed timing, uncomfortable sleeping ambience and longer exposure to screen time (Television & electronic gadgets) had greater PSQI scores. CONCLUSION The current study explicitly states that sleep deprivation is one of the global burden among adolescents and better understanding of sleep hygiene and sleep pattern will help to reduce the incidence of sleep related lifestyle disorders.
