| Summary: | Introduction: Sleep deprivation and metabolic disorders are rising in parallel worldwide. The academic pressures and rigorous schedules associated with the medical curriculum may predispose college students to erratic sleep patterns. Social Jetlag (SJL) is the imbalance between sleep duration on workdays and free days, resulting from the mismatch between a person’s biological rhythm and the daily timing set by social obligations. College students often attempt to compensate for sleep debt during the weekends. Changes in sleep patterns have been linked to the development of insulin resistance, diabetes mellitus and cardiovascular diseases in adults.
Aim: To determine the prevalence of sleep disturbances and to evaluate the relationship between sleep quality, SJL and Metabolic Syndrome (MetS) in young adults attending medical school.
Materials and Methods: In this analytical cross-sectional study conducted over two months, from August 2022 to September 2022, 153 medical students from SRM Medical College Hospital and Research Centre, Kattankulathur, Chengalpattu, Tamil Nadu, India participated to evaluate the relationship between sleep disturbances and MetS. Sleep quality and SJL were assessed using the Pittsburgh Sleep Quality Index (PSQI) questionnaire and the Munich Chronotype Questionnaire (MCTQ). The presence of MetS was determined according to the criteria provided by the National Cholesterol Education Program - Adult Treatment Panel III (NCEP ATP III). Descriptive statistics, Chi-square (c2) tests, Spearman correlation, logistic regression analysis and odds ratios were used to analyse the data.
Results: The mean age of the study participants was 20.24±1.12 years. The prevalence of sleep disturbance (PSQI score above 5) demonstrated in the present study is 63/153 (41.2%) using the PSQI questionnaire. Nearly 40/83 (48.2%) of the female students had sleep disturbances. Short sleep duration (p-value=0.04) was found to be associated with MetS, with a reduction in sleep duration by one hour increasing the odds by 2.12. Out of the 153 student participants, 9.8% (n=15; 8 males and 7 females) met the criteria for MetS.
Conclusion: A reduction in sleep duration was associated with an increased risk of developing MetS. |
