Relationships Between Physical Activity, Sleep, Psychological Well-Being, and Academic Performance Among Native American College Students

Background: College students’ well-being is a critical determinant of academic success, and for Native American students, cultural strengths, resilience, and community support are key in fostering persistence in higher education. Alongside these assets, health behaviors are key contributors to psychological well-being (PWB) and academic performance. This study examined how modifiable health behaviors, such as physical activity (PA) and sleep duration, relate to PWB and academic performance among Native American college students. Methods: A secondary data analysis was conducted using a nationally representative sample of Native Americans (N = 1914) from the Spring 2023 American College Health Association-National College Health Assessment (ACHA-NCHA) survey. Independent variables include meeting PA guidelines (≥150 min moderate or ≥75 min vigorous/week) and sleep duration (categorized as poor or good). The Diener Flourishing Scale measured PWB. Academic performance was measured based on self-reported cumulative grade averages. Findings: Biological sex and PA were significantly associated, χ2 = 40.60, p < 0.001, with a higher proportion of males meeting PA guidelines. Students with good sleep reported higher PWB than others, F(1, 1817) = 62.08, p < 0.001. Similarly, students who met PA guidelines reported higher PWB, F(1, 1817) = 35.71, p < 0.001. Poor sleep was associated with lower odds of higher academic performance (B = −0.33, p < 0.001). Contrarily, PA was not significant (p = 0.350). PWB was positively associated with academic performance (B = 0.031, p < 0.001). Conclusions: Sleep and PWB are key factors associated with both PWB and academic performance, while PA is associated with PWB. These findings highlight the importance of relevant interventions that promote these factors to support overall well-being, academic success, and retention among Native American college students.
