RESUMO
BACKGROUND: This study examined the relationship between physical activity (PA) and academic performance and retention among college students using accelerometer data while controlling for sex and socioeconomic background. METHODS: Data were collected from 4643 first-year college students at a private university in the south-central United States who began their studies in the Fall semesters between 2015 and 2022. Daily step counts were collected using accelerometers worn as part of the institutions PA requirements. The expected family contribution was calculated based on information provided on the Free Application for Federal Student Aid. Grade point average (GPA) and retention data were collected directly from official university databases. RESULTS: Female students generally had lower median age and steps count and a higher median GPA than males. The retention rates from fall to spring and fall to fall were 95.9% and 83.8%, respectively, with no significant difference in retention rates between males and females. GPA was significantly positively correlated with steps, expected family contribution, and age, and negatively correlated with being male and having an expected family contribution of zero. The fall to spring retention rate was significantly positively correlated with steps and GPA. CONCLUSIONS: The study's findings suggest that increasing levels of PA, as measured by daily step counts, may be effective in promoting academic performance and retention, even when controlling for sex and socioeconomic background. The use of device-based measures of PA in this study contributes to the literature on this topic, and policymakers and educational institutions should consider interventions focused on academic performance and physical activity to help students persist.
RESUMO
BACKGROUND: Personality traits are known factors that may influence levels of physical activity and other healthy lifestyle measures and behaviors that ultimately lead to health problems later in life. Participants And Procedure: The aim of this study was to examine the association between personality traits (HEXACO) and levels of physical activity and resting heart rate (RHR) - measured using Fitbits, BMI, and a self-reported whole-person healthy lifestyle score for N = 2580 college students. Data were collected and analyzed for students enrolled in a University Success type course from August 2017 to May 2021. The relationships between HEXACO personality traits and various physical activity and healthy lifestyle behaviors were analyzed by building several multiple regression models using R version 4.0.2. Results: In general, students who are extraverted were more physically active and students who are more open to experience had a higher RHR, even when controlling for gender. Females and males however had different profiles as to how personality influenced physical activity and other health-related measures. Male extraverts with high negative emotionality scores tend to be more physically active, whereas females tend to be more physically active when they were high in extroversion and conscientiousness, and low in openness to experience. BMI values were higher for female participants with high honesty-humility and low agreeableness and conscientiousness scores. Females also had a lower RHR for high honesty-humility and emotionality and low conscientiousness scores. CONCLUSIONS: Personality can influence levels of physical activity, RHR, and BMI. This is especially true of women. Being aware of one's personality and the relationship of personality traits to levels of physical activity and other measures of leading a healthy lifestyle can be beneficial in determining strategies to improve long-term health outcomes.
