Abstract

The objective of this study was to observe the sleep latency, day dysfunction, actual sleep hours and sleep efficiency in first year medical students and its relation to their BMI.

A total of 68 first year medical students answered the Pittsburgh Sleep Quality Index (PSQI) Questionnaire. Height and weight of the participants were measured and Body Mass Index (BMI) calculated.

A suggestive significance of P=0.08 for sleep efficiency score across various category of BMI indicates that higher BMI is associated with worse sleep efficiency scores.

Medical students should maintain their BMI in the normal BMI range by taking nutritious food and engaging in adequate physical activity as normal BMI is associated with good sleep.
