Assessment of osteoarticular morbidity in regions with different boron concentrations in deep drinking water of the Republic of Moldova

Abstract

Introduction. Even if boron is not yet recognized as an essential element for the human body, its insufficient intake is considered harmful, especially for the osteoarticular system. A daily intake of at least 3 mg of boron can fortify bone mass and prevent the onset of osteoarthritis, rheumatoid arthritis, and osteoporosis. This research aims to assess the morbidity caused by rheumatoid arthritis and inflammatory polyarthropathies in the population from regions with different boron concentrations in deep drinking water of the Republic of Moldova.

Material and methods. Two full-length descriptive observational studies were conducted: one on osteoarticular morbidity caused by rheumatoid arthritis and inflammatory polyarthropathies (incidence and prevalence), and one on boron concentrations in deep drinking water (public wells and artesian wells). Following national regulations, the Republic of Moldova was divided into three distinct boron-related areas, and in each of them, the boron trend overlapped with the morbidity trend.

Results. In the below-the-limit boron area, the research hypothesis was confirmed in two out of three districts, by overlapping osteoarticular morbidity with boron concentrations in deep drinking water and their trendlines. In the limit-level boron area, boron concentrations in drinking water do not appear to influence the studied osteoarticular morbidity in either district. In the above-the-limit boron area, unlike in previous research, trends for boron concentrations in public wells and artesian wells were opposite to those of the incidence and prevalence of rheumatoid arthritis and inflammatory polyarthropathies, confirming the research hypothesis.

Conclusions. Out of the three studied areas, the expected phenomenon of low morbidity and high boron concentrations, and vice versa, was observed in two below-the-limit boron districts and two above-the-limit boron districts. The results can be expanded upon in further research in the field.
