To explored the relationship between the Dietary Oxidative Balance Score (DOBS) and the risk of developing osteoporosis in patients with chronic kidney disease (CKD) based on data from the National Health and Nutrition Examination Survey (NHANES).
The study population was selected from CKD patients aged 40 years and above in a total of four survey cycles of NHANES 2007—2008, 2009—2010, 2013—2014, and 2017—2018, and the association between DOBS and the risk of developing osteoporosis in CKD patients was assessed using weighted logistic regression, with smoothed curve fitting demonstrating the dose-response relationship between the two and subgroup analyses based on age and gender.
A total of 2 281 participants were included in this study, and the fully adjusted model (Model 3) found that higher DOBS significantly reduced the risk of osteoporosis in CKD patients, with an OR of 0.400 (95% CI: 0.211-0.758) in the highest quartile group of DOBS (Q4) compared with Q1. Smoothed curve fitting revealed a negative linear dose-response relationship between DOBS and the prevalence of osteoporosis. Subgroup analysis revealed that the negative association between DOBS and osteoporosis was more significant in female and ≥65-year-old CKD patients, respectively.
In this study, we found that the relationship between DOBS and the risk of osteoporosis in CKD patients was linearly negatively correlated and showed gender and age differences, but further studies are needed to confirm this.
