Background: Limited information is available on the sleep and propensity for daytime sleepiness in young medical doctors of India.
Methods: The 2-week self-reported data surrounding sleep and exercise habits, and the Epworth sleepiness scale (ESS) score obtained from volunteering doctors of a tertiary care hospital in India, were summarized as median (Q1-Q3). Comparisons with Mann-Whitney U test and correlations with Spearman’s rank correlation were done.
Results: Forty-seven doctors (28 [26-33] years, 16 males) reported a total sleep duration (TSD) of 6.3 (6-6.7) hours, sleep latency of 9 (5.1-15.8) minutes, and ESS score of 8 (5-10). The number of days (out of 14) when the subjective feeling of ‘refreshed’, ‘somewhat refreshed’, and ‘fatigued’ was experienced was respectively 6 (2-9), 5 (3-8), and 1 (0-4). Junior-level doctors experienced more days of ‘fatigue’ than senior-level doctors (3 [0-4.3], 0 [0-0]; p = 0.002). Doctors who did not exercise reported greater days of fatigue than those who exercised (2 [0-4.8], 0 [0-2]; p = 0.047).
Conclusions: The young doctors of our study slept less than the recommended amount of 7 hours by the American Academy of Sleep Medicine. Their short sleep latency and normal propensity for daytime sleepiness, though encouraging, may be an effect of insufficient sleep and mentally alerting daytime schedule respectively. Notably, we found a positive association between exercise habits and subjective restoration following sleep in our study population. The sleep requirements and sleep structure among Indians are yet to be established. Our findings add to the data on sleep in the Indian context.
