Individual differences in diurnal preferences and circadian rhythms are viewed as an interesting dimension of human personality. The impact of health-related behaviours and sociodemographic profile to diurnal preferences of an individual is acknowledged but is relatively understudied. Our study aims to estimate the distribution of morningness- eveningness and their prevalence among medical students and analyse their correlation with health-related behaviours including smoking, alcohol consumption, physical activity and electronic device addiction. A cross-sectional study was conducted from April 2020 to May 2020 in Melaka-Manipal Medical College (MMMC). Self-reported data was obtained using online questionnaire that has been distributed to students (n=174). The questionnaire consist of 5 sections including socio-demographic profile, smoking, alcohol consumption, physical activity, electronic device addiction and moringness eveningness questionnaire. The morningness eveningness prevalence was determined by calculating the score of each participants and classifying them into 5 groups which are definite morning, moderate morning, intermediate, definite evening and moderate evening. Data analysis was done using Epi Info (version, level of significance was set at P<0.05 and statistical test used was Chi Square test. High prevalence of intermediate preferences was found among the students with significant correlation to age, alcohol consumption and addiction to electronic device. We found higher prevalence of intermediate pattern in age group ≤23 years (76.47%) old and > 23 years old (60.00%). There is slightly higher morningness (13.45%) prevalence in the earlier group compare to eveningness (10.08%) meanwhile the morningness and eveningness prevalence is equal (20.00%) in later group. The students who consumed alcohol were more intermediate type (68.09%). Students who consume alcohol (19.15%) have higher eveningness preference compare to those who don’t drink alcohol (4.72%) meanwhile those who don’t drink alcohol (22.83%) have higher morningness preferences compare to those who drink alcohol (12.77%). Student who are addicted to electronic device were also more intermediate type (81.05%). Students who are addicted to electronic device (8.42%) have higher eveningness preference compare to those who are not addicted (7.86%) meanwhile those who are not addicted to electronic device (31.65%) have higher morningness preferences compare to those who are addicted (10.53%).
