Serum antioxidant status and mortality from influenza and pneumonia in US adults.

ABSTRACT:

Objective

We examined the association between serum antioxidant status and mortality from influenza and pneumonia in US adults.

Design

Serum concentrations of antioxidants included vitamin C, vitamin A, vitamin E, sum of α- and β-carotene, β-cryptoxanthin, lutein + zeaxanthin and lycopene. We computed total antioxidant capacity (TAC) as a measure of composite antioxidant status in serum. Survey-weighted Cox proportional hazard models were used to compute hazard ratios (HR) and 95 % CI comparing quartiles of each antioxidant and TAC.

Setting

Data from the US National Health and Nutrition Examination Survey (NHANES)-III.

Participants

A total of 7428 NHANES-III participants ≥45 years of age.

Results

With a weighted-median follow-up of 16·8 years, 154 partic
