Abstract

This observational study compared bone health biomarkers, bone mineral density (BMD),dietary habits, and physical activity levels of men (n=31) and non-estrogen supplementing postmenopausal women (n=23) divided according to duration of proton pump inhibitor (PPI) therapy; more than 5 years (n=16), less than 5 years (n=15), and no PPI therapy (n=23). The shortest duration of PPI therapy was 2 months and the longest duration of PPI therapy was 25 years with a mean duration of 7.5 years. No significant differences were found between measures of spine BMD, urinary deoxypyridinoline (bone resorption), urinary calcium and magnesium, serum osteocalcin (bone formation), serum parathyroid hormone, serum magnesium, serum 25 hydroxyvitamin D3, dietary and supplement intake, or physical activity levels. However, mean hip BMD was higher in females than in males in participants who took PPI therapy for any duration. In the no PPI therapy group, hip BMD was not significantly different between genders. These results suggest that there may be no measurable or clinically significant negative effects of long term PPI therapy on bone health. However, men may be at higher risk of hip fracture when taking long-term PPI therapy than women.
