Association of Oxidative Balance Score With All-Cause and Cardiovascular Mortality Among Hypertensive Adults.

ABSTRACT:

Background

The Oxidative Balance Score (OBS) is a new measure for assessing systemic oxidative stress, where higher scores indicate increased exposure to antioxidants. However, the relationship between the OBS and mortality in individuals with hypertension remains unclear.

Methods

This study evaluated 8151 hypertensive individuals from the National Health and Nutrition Examination Survey (NHANES) (2001-2018), utilizing data from the National Death Index, tracked through December 31, 2019. The association between OBS and mortality (cardiovascular and all-cause) was examined using multivariable Cox regression models.

Results

During a median follow-up of 9.7 years, which included 1692 deaths (461 of which were cardiovascular), multivariable Cox regression showed the high
