Résumé
With the advancement in technology and change in lifestyle, social shifts have been moving towards night life and the correlation between obesity and sleep duration has become even much stronger. Present study was done to find out any correlation between obesity with sleep patterns and cardiorespiratory fitness among the medical college students of MMIMSR, Mullana. Methods: 500 participants, of which 250 male and 250 female student participants of age group 18-25 years were randomly taken from Maharishi Markandeshwar Institute of Medical Sciences and Research, Mullana [Ambala] for the study. The students were examined thoroughly under similar laboratory condition so as to exclude those with the history of any acute or chronic illness or on long term medication or with a history of traumatic injuries. Pittsburg sleep quality Index (PSQI) scale was taken to access sleep patterns. Each student was given a standardized and validated questionnaire in a form of proforma to determine their sleep patterns. By using Quetelet index, BMI of each student was calculated and Cardiorespiratory fitness was estimated indirectly by following the protocol of Queen’s College Step Test [QCT] method by calculating VO2max. Results: The result of our study showed highly positive significant association and correlation between obesity and sleep patterns in both male and female groups and highly significant correlation between obesity and cardiorespiratory fitness in both male and female groups. Conclusion: Proper awareness and education at early stage is extremely important to impress the consequences of low sleep duration and in prevention of development of obesity and improvement in the cardiorespiratory fitness.
