Associations between lumbar bone mineral density, serum 25-hydroxyvitamin D and history of kidney stones in adults aged 30–69 years in the USA (NHANES 2011–2018)

Abstract

ObjectivesMost kidney stones contain calcium, which is closely associated with human bone health. Therefore, we aimed to determine the relationship between the history of kidney stones and human bone health. This study examined the associations between lumbar bone mineral density (BMD), serum 25-hydroxyvitamin D (25-OHD) and a history of kidney stones in individuals aged between 30 years and 69 years.Design and data analysisA multivariate logistic regression model was used to estimate the relationship between lumbar BMD, serum 25-OHD levels and kidney stones in this cross-sectional study. All models incorporated survey sample weights and were adjusted for covariates.SettingNational Health and Nutrition Examination Survey (NHANES) 2011–2018. The exposure and outcomes of this study included the lumbar BMD and presence of kidney stones.ParticipantsAll the 7500 participants for this cross-sectional survey were selected from the NHANES between 2011 and 2018.Main outcome measuresThe main outcome of this study was the presence of kidney stones. The interviewers asked the questions on kidney stones while the respondents were at home, using a computer-assisted personal interview system.ResultsLumbar BMD was negatively correlated with a history of kidney stones in all three multivariate linear regression models; the negative association existed in all genders after adjusting for all confounding factors. In the multiple regression analysis, there was an interaction between serum 25-OHD and lumbar BMD (p<0.05) regarding the influence on kidney stones; the negative association between lumbar BMD and kidney stones was more obvious in the higher 25-OHD group (≥50 nmol/L).ConclusionThe study results suggest that maintaining a high lumbar BMD may reduce the incidence of kidney stone formation. Simultaneously, maintaining a high serum 25-OHD level may be more beneficial in preventing the occurrence or recurrence of stones while ensuring a high lumbar BMD.

Bone mineral density and Trabecular Bone Score in patients with kidney stone disease

“…Ta king into account the presence of one of the important rea sons for the insufficient use of calciumcontaining products and supplements is the fear of provoking nephrolithiasis, the study of BMD is a very important aspect of metaphy laxis. Some research results suggest that a higher BMD may contribute to a reduction in the formation of KSD [10]. Therefore, to achieve this goal, it is recommended to in clude calciumcontaining drugs and food products in the daily diet.…”
