Physical activity and sleep quality in relation to mental health among college students

Objective To examine the associations and interactive effects of physical activity and sleep quality on mental health among Indian college students. Method A cross-sectional study was conducted among Indian college students. The sociodemographic data and body mass index were obtained from a convenience sample of 617 college students, age range from 18 to 30 years, including both genders (314 men, 51%). All participants completed three questionnaires: the Hospital Anxiety and Depression Scale, the International Physical Activity Questionnaire-Short Form, and the Pittsburgh Sleep Quality Index. Questionnaires were evaluated to ascertain the subjects' mental health level, physical activity level, and sleep quality. Analyses were conducted with binary logistic regression models. Result The mean (S.D.) anxiety and depression scores were 9.3 +/- 4.4 and 7.4 +/- 2.5 respectively, with anxiety and depression scores ranging from 0 to 20 and 0-17, respectively. The prevalence of anxiety (30%) was more than that of depression (18%). Out of the total participants, 51% reported having low physical activity levels, and 51% had poor sleep quality. Odds ratio calculations indicated that the participants physical activity levels (moderate and high) were significantly and inversely associated with scores for anxiety (OR=0.16 and 0.96; p=0.001) and for depression (OR=0.11 and 0.96; p=0.001).The poor sleep quality was significantly positively associated with anxiety (OR=1.38) and depression OR=1.58 (p=0.001). Conclusion Mental health problems are common among both male and female college students. Significant associations were found between physical activity levels and sleep quality with mental health.
