Study of the knowledge, beliefs, and practice of sleep among medical undergraduates of Tamilnadu, India.

CONTEXT

Sleep-related problems are common in young adults who are enrolled in professional colleges due to academic and social pressures, which may subsequently have serious consequences.

OBJECTIVES

This study was conducted to find out whether final-year medical undergraduates possess basic, clinically relevant knowledge (K) regarding sleep and sleep-related problems and to discover their beliefs (B) regarding sleep and sleep hygiene. We also wanted to assess their sleep practices (P) and suggest remedial measures, if necessary.

DESIGN AND SETTING

Six hundred fifteen final-year medical undergraduates of both sexes belonging to 6 medical colleges of Tamilnadu state, India, were given a self-administered, anonymous questionnaire to test their basic knowledge (11 items), prevailing beliefs regarding sleep (including sleep hygiene [13 items]), and their sleep practices (6 items).

RESULTS

In all 3 domains tested (K, B, and P), there was no significant difference between sex. An appreciable percentage scored < or = 70% marks ("good") only in K and P (63.9% and 79.5% of all participants, respectively), whereas only a very small percentage scored "good" in B (9.1%). There was no difference in K, B, or P in terms of sex or domiciliary status except for a significant difference (P < .012) regarding beliefs between urban and rural groups. There was also no correlation between knowledge and beliefs or between knowledge and practice.

CONCLUSION

We conclude that future doctors have insufficient knowledge with more misconceptions (indirectly reflecting inadequate knowledge) regarding sleep. Hence, there is a compelling need to develop an educational strategy to overcome misconceptions and improve knowledge regarding sleep-related problems and proper sleep practices among students.
