Osteoporosis is a progressive metabolic bone disorder characterized by reduced bone mass and deterioration of bone microarchitecture, leading to increased fragility and fracture risk. Although commonly associated with older adults, the foundation of osteoporosis prevention is established during adolescence and early adulthood through the optimization of peak bone mass. This study aimed to examine the relationship between osteoporosis knowledge and physical activity levels among undergraduate nutrition students as an early preventive strategy. A quantitative cross-sectional design was applied, involving 92 first- and second-year students of the Nutrition Study Program, Faculty of Sport and Health Education, Universitas Pendidikan Indonesia. Data were collected using a validated structured questionnaire measuring osteoporosis knowledge and physical activity behavior. Statistical analysis was conducted using the Chi-Square test, followed by Cramer’s V to assess effect size. The findings revealed that 77.2% of respondents had a high level of osteoporosis knowledge, whereas 57.6% engaged predominantly in light physical activity. The Chi-Square test indicated a significant association between knowledge and physical activity (p = .001), with a Cramer’s V value of 0.49, suggesting a moderate-to-strong relationship. These results demonstrate that knowledge contributes substantially to physical activity behavior; however, adequate knowledge alone does not guarantee optimal activity levels. The study underscores the need for integrative health promotion strategies that combine educational reinforcement, behavioral motivation, and supportive campus environments to strengthen early osteoporosis prevention among young adults.
