Relationship between Academic Performance with Physical, Psychosocial, Lifestyle, and Sociodemographic Factors in Female Undergraduate Students

BACKGROUND The purpose of this study was to investigate the relationship between physical, psychosocial, lifestyle and sociodemographic factors with academic performance in female undergraduate students. METHODS One hundred undergraduate female students from the Faculty of Science at the University of Quebec at Montreal participated in this study (mean age = 24.4 ± 4.6 years old). All participants provided their university transcript and had to complete at least 45 course credits from their bachelor degree. Body composition (DXA), handgrip strength, estimated maximal oxygen consumption (VO2 max) (Bruce Protocol) and blood pressure were measured. Participants also completed a questionnaire on their psychosocial, academic motivation, lifestyle and sociodemographic profile. RESULTS Significant correlations were observed between GPA with estimated VO2 max (r = 0.32), intrinsic motivation toward knowledge (r = 0.23), intrinsic motivation toward accomplishment (r = 0.27) and external regulation (r = -0.30, P = 0.002). In addition, eating breakfast every morning and being an atheist was positively associated with academic performance (P < 0.05). Finally, a stepwise linear regression analysis showed that external regulation, intrinsic motivation toward accomplishment, VO2 max levels and eating a daily breakfast explained 28.5 % of the variation in the GPA in our cohort. CONCLUSIONS Results of the present study indicate that motivational, physical and lifestyle factors appear to be predictors of academic performance in female undergraduate students.
