This paper presents the outcome of study conducted among 150 normal individuals using Morningness-Eveningness Questionnaire by J.A. Horne and O. Ostberg , to know whether ‘owl/lark’ nature ( morningness/eveningness) is a function of age, B.M.I. and B.S.A. and if at all so, which one is a better predictor of “morningness/ eveningness”.
The results of MEQ scores suggest that the subjects (N=150) could be assigned three major types, i.e., morning type (119), intermediate type (30) and evening type (01). When the simple regression analysis of these results was carried out, the coefficients of significance gave values 0.094, 0.805 and 0.189 for age, B.M.I. and B.S.A. respectively. This indicates that age, B.M.I. and B.S.A. are not good predictors of morningness, eveningness traits in the sampled population.
