Assessment of the epidemiological situation with parathyroid gland diseases in the Chuvash Republic based on data from the All-Russian Registry of Patients with primary hyperparathyroidism. To analyze the data of patients with primary hyperparathyroidism in a retrospective cohort study from 2014 to 2025 at the clinical base of the Republican Clinical Hospital for War Veterans of the Ministry of Health of Chuvashia.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>MATERIALS AND METHODS<\/jats:bold>\n                    . The data on the Chuvash Republic from the All-Russian Registry of patients with primary hyperparathyroidism are analyzed. In the course of a retrospective cohort study (2014\u20132025), a cohort of patients registered at the Republican Clinical Hospital for War Veterans of the Ministry of Health of Chuvashia was analyzed. For statistical data processing, a descriptive method was used with the calculation of absolute and relative values (percentages).\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>RESULTS<\/jats:bold>\n                    . It was found that the prevalence of parathyroid gland pathology in the region is 73.4 cases per 100,000 population. Key epidemiological features were identified: a pronounced predominance of women (88.9%) in the older age group, an uneven geographical distribution with a concentration of cases in urbanized areas (Cheboksary, Novocheboksarsk), as well as a significant increase in detection in recent years. The data obtained indicate the influence of both organizational factors (availability of specialized care) and possible environmental risks (imbalance of trace elements in water sources) on the prevalence of pathology.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>CONCLUSION<\/jats:bold>\n                    . The implemented electronic registry has proven its effectiveness for monitoring morbidity, planning medical care and conducting scientific research, which determines the prospects for its further development to optimize the system of endocrinological care in the region.\n                  <\/jats:p>","DOI":"10.14341\/probl13663","type":"journal-article","created":{"date-parts":[[2026,7,27]],"date-time":"2026-07-27T14:47:35Z","timestamp":1785163655000},"page":"12-18","update-policy":"https:\/\/doi.org\/10.14341\/crossmarkpolicy2018","source":"Crossref","is-referenced-by-count":0,"title":["Analysis of epidemiological indicators of parathyroid gland diseases in the Chuvash republic based on registry data"],"prefix":"10.14341","volume":"72","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-9597-4145","authenticated-orcid":true,"given":"G.
