Abstract

Background: From the past few decades, disturbed sleep pattern has grown to be a hallmark of modern-day society among the adolescents and in adults. Both are having disturbed sleep patterns with average sleep duration of 7 h per night. Smartphones, tablets, and television which are the remarkable source of information and entertainment have robbed sleep time and have led to voluntary sleep restriction as self-reported by them and it has become a serious barrier to health development. Along with-it, high blood pressure (BP) levels are influenced by high body mass index (BMI) and low cardiorespiratory fitness which are among the most important cardiovascular disease risk factors. However, how sleep attenuates the individuals BMI, cardiorespiratory fitness and BP in adolescents are uncertain.

Aims and Objectives: The aim of this study was to analyze whether the disturbed sleep pattern is a mediator between body composition, Cardiorespiratory fitness (CRF), and BP levels in young adolescents.

Materials and Methods: This study was a cross-sectional study which involved students of MMIMSR (n = 500), of which 250 male and 250 female participants were recruited. Initial explanation about the aim and purpose of the study, test procedure, method of testing, and instruction of how to perform the test was given. All the participants were examined under similar laboratory conditions. Detailed history with thorough clinical examination were done. All basal parameters such as heart rate, BP, and respiratory rate were also measured.

Results: In our study, disturbed sleep patterns were highly significantly (P < 0.01) associated with high BMI which acted as a mediator between low CRF and high BP in both the participants. Our results highlighted the importance of a sleep in maintaining a healthy lifestyle, CRF and to prevent hypertension in young adolescents.

Conclusion: The findings of our study are consistent with the hypothesis that disturbed sleep might be one of the reasons which influence BMI and long-term cardiovascular health.
