ABSTRACT Objectives The association between vegetarian dietary patterns and bone health remains inconsistent, particularly in young adult populations. This study aimed to investigate the association between adherence to a vegetarian dietary pattern and bone mineral density (BMD) in a sample of young adult women. Methods The study included 648 young adult women from Slovakia (67 reporting adherence to a vegetarian diet and 581 omnivores). BMD was assessed using quantitative ultrasonography. Baseline demographic and lifestyle information was collected using a structured questionnaire. Linear regression analyses were applied to examine independent associations between dietary pattern and BMD. Results Women reporting adherence to a vegetarian diet exhibited significantly higher speed of sound (SOS) at the radius (4111.0 ± 124.7 vs. 4068.4 ± 111.2 m/s; p = 0.017) and higher z ‐score (0.09 ± 1.29 vs. −0.27 ± 1.09; p = 0.036) compared with omnivorous women. In linear regression analyses, adherence to a vegetarian dietary pattern was independently associated with higher SOS and z ‐score values, whereas smoking status, physical activity, and body weight were not retained in the final models. Conclusions Women reporting adherence to a vegetarian dietary pattern exhibited higher SOS and z ‐score values at the radius compared with their omnivorous peers. These findings suggest that adherence to a vegetarian dietary pattern is associated with differences in bone characteristics in young adult women.
