The association between oxidative balance score and muscular dystrophies

Abstract

IntroductionThis research utilized data from the NHANES 2011–2018 study to investigate the connection between the Oxidative Balance Score (OBS) and muscular dystrophies.MethodsThis study is a cross-sectional, observational, secondary analysis utilizing data from the NHANES 2011-2018. Spearman’s correlation, chi-square tests, logistic regression, and restricted cubic spline plots were employed for statistical analyses.ResultsThis association remained significant after adjustment for various demographic and medical history factors (For continuous OBS: crude model, odds ratio [OR], 0.95, 95% confidence interval [CI:] 0.94, 0.97, p < 0.001; Model 1, OR, 0.94, 95% CI: 0.92, 0.96, p < 0.001; Model 2, OR, 0.95, 95% CI: 0.93, 0.97, p < 0.001; Model 3, OR, 0.95, 95% CI: 0.93, 0.97, p < 0.001; In quartile Q4 vs. Q1: Crude model, OR, 0. 42, 95% CI: 0.26, 0.66, p < 0.001; Model 1, OR, 0.33, 95% CI: 0.21, 0.52, p < 0.001; Model 2, OR, 0.37, 95% CI: 0.23, 0.58, p < 0.001; Model 3, OR, 0.38, 95% CI: 0.23, 0.60, p < 0.001). Restricted cubic spline (RCS) analysis further supported this inverse relationship, suggesting that OBS values above 10 may confer protection against muscular dystrophies (p for overall <0.001, p for non-linear = 0.536). However, the relationship between OBS and muscular dystrophies was not statistically significant in the subgroups with education level below high school, presence of cancer, or diabetes (p = 0.735, p = 0.574, p = 0.409, respectively).ConclusionThe study found a significant inverse correlation between the OBS and muscular dystrophies, suggesting that individuals with higher oxidative balance had a lower risk of developing muscular dystrophies. The study highlights the potential role of oxidative balance in muscular dystrophies prevention and management.
