Association of Body Mass Index and Physical Activity with Psychological Stress among Female Undergraduate Students in Nigeria

Abstract

A bstract Background: The prevalence of stress among university students has emerged as a significant concern, with notable impacts on their academic performance and overall well-being. Despite the growing body of literature on the association between body mass index (BMI), physical activity (PA), and stress, there is a shortage of research in Nigeria. Objective: This study aimed to investigate the associations of stress with BMI and PA among female students in Nigeria. Materials and Methods: A cross-sectional survey design was employed, and data were collected from a convenience sample of 301 female undergraduate students at a Nigerian university. The Perceived Stress Scale and International PA Questionnaire—Short Form assessed stress and PA. BMI was calculated from the participant’s weight and height. Results: Participants’ mean BMI was 22.5 ± 3.8 with 68.4% falling within the normal BMI range. A greater percentage reported low levels of PA (60.8%) and moderate stress levels (67.4%). There was no significant relationship between BMI and stress ( r = −0.090, P = 0.131). However, a low level of PA was associated with increased stress ( r = −0.131, P = 0.027). Conclusion: PA significantly influences stress. Universities should facilitate an exercise-friendly environment and encourage PA programs for female students.
