We evaluated the role of Helicobacter pylori (H. pylori)-related chronic gastritis in the development of osteoporosis in a population-based study. A total of 1690 subjects in the cohort of the Research on Osteoarthritis/ osteoporosis Against Disability (ROAD) were investigated, and the association between gastritis and osteoporosis was evaluated by the presence of serologically assessed H. pylori-related chronic gastritis and its stage, based on H. pylori antibody titer and pepsinogen. The presence of the gastritis was associated with significantly lower bone mineral density (BMD) assessed by dual-energy x-ray absorptiometry and a significant risk of lower BMD was observed in femoral neck (adjusted odds ratio [OR]: 0.78, 95% confidence interval [CI]: 061-0.99). The progression of the gastritis appeared to further increase the risk. In the stage of non-atrophic gastritis, the risk of lower BMD was significantly high, especially in a subgroup with higher gastritis activity in the femoral neck (adjusted OR: 0.61, 95% CI: 0.42-0.89). Meanwhile, in the stage of atrophic gastritis, the highest and significant risk of lower BMD was observed in a subgroup with the most extensive and severe atrophy in femoral neck (adjusted OR: 0.62, 95% CI: 0.42-0.91). These results suggest that H. pylori-related chronic gastritis is involved in the risk of osteoporosis, with higher activity of gastritis and more extensive atrophy leading to further increased risk. The serologically assessed stage of the gastritis could be used to identify a high-risk group for osteoporosis in H. pylori-infected subjects from general population.
