Abstract

Chronotype reflects on the variability of an individual in the phase of entrainment and its relationship with the preference of activity-rest in a given 24-hour day. On the other hand, body composition serves as an indication on the health status of an individual. This narrative review focuses on summarising the current studies on the association between chronotype and its relationship with body composition. In this cross-sectional study, 383 total of university students from Tunku Abdul Rahman University of Management and Technology were recruited from the age of 18 above. The subjects were assessed by answering MCTQ questionnaires on chronotype topics and their body composition were taken using Inbody 270. The overall median score of Body Mass Index (BMI) on morning, intermediate and evening chronotype was, 19.7 (IqR 2.8), 20.7 (IqR 4.1) and 20.6 (IqR 3.8), respectively. As for percentage of body fat, the overall median score on morning, intermediate and evening chronotype was, 29.2 (IqR 10.6), 25.6 (IqR 13.3) and 21.7 (IqR 12.2), respectively whereas the overall median score of visceral fat level on morning, intermediate and evening chronotype was, 4.5 (IqR 4.5), 5.0 (IqR 4.0) and 4.0 (IqR 3.5), respectively. No significant different is found between the association of chronotype and BMI (p = 0.553), body fat percentage (p = 0.093) and visceral fat level (p = 0.320). In conclusion, this finding has provided the latest evidence on chronotype and body composition which act as a reference for future researchers. More studies need to be conducted on the chronotype and body composition association. Keywords: chronotype, body composition, anthropometric measurements, circadian rhythm
