Compulsive exercise among college students: 5-year time trends in prevalence and demographic, substance use, and mental health correlates

Purpose To provide 5-year time trends in prevalence and demographic, substance use, and mental health correlates of compulsive exercise among a national sample of college men and women. Methods We analyzed 4 academic survey years (2016-2020; N = 8251) of the national (USA) Healthy Minds Study. Compulsive exercise was measured by self-report of any occurrence of compulsive exercise in the past 4 weeks. Unadjusted prevalence of compulsive exercise in the past 4 weeks was estimated across the 4 survey years by sex. Multiple logistic regression analyses were conducted among the pooled sample and stratified by sex to estimate the associations between compulsive exercise in the past 4 weeks and demographic, substance use, and mental health correlates. Results Among the pooled sample, 11% (95% confidence interval [CI] 9.60-12.42%) of men and 17% (95% CI 15.86-18.24%) of women reported compulsive exercise in the past 4 weeks. Prevalence across the 4 survey years remained stable among men and women. Higher body mass index was associated with greater odds of any compulsive exercise in the past 4 weeks among men, while any sports participation was associated with greater odds of any compulsive exercise in the past 4 weeks among women. Compulsive exercise in the past 4 weeks was associated with greater odds of all mental health symptoms and illicit drug use among men and women, and higher odds of alcohol use among women. Conclusion Compulsive exercise is relatively common among college men and women and is associated with substance use behaviors and poor mental health symptoms.
