The purpose of this non-experimental quantitative correlational study was to investigate the relationship between academic achievement and health in a national sample of college students using quantitative data analysis. Specifically, the researcher analyzed the relationship between three health-promoting behaviors (physical activity, strength training, and fruit and vegetable consumption), three negative health behaviors (cigarette, e-cigarette, and opioid use) and obesity with GPA.

Cross-sectional data on student health collected from the American College Health Association’s National College Health Assessment II (ACHA-NCHA-II) and completed by 426,650 college students from 650 U.S. colleges during the semesters between 2015 and 2019 formed the foundation for this research. Nine research questions were addressed using a series of chi square tests.

Results showed there was a significant positive relationship between health behaviors and grade average. Students who met the recommendations for fruit and vegetable consumption, moderate activity and vigorous physical activity were more likely to have GPAs than those who did not. Students who used cigarettes, opioids, or were obese were more likely to have GPAs.
