Association of serum levels of antioxidant micronutrients with mortality in US adults: National Health and Nutrition Examination Survey 1999-2002.

ABSTRACT:

Objective

To examine associations between serum antioxidant levels and mortality (all-cause, cancer and CVD) among US adults.

Design

We examined the risk of death from all-cause and cause-specific mortality associated with serum antioxidant (vitamin E and carotenoids) and vitamin A levels using Cox regression models to estimate hazards ratios (HR) and 95 % CI.

Setting

The National Health and Nutrition Examination Survey (NHANES) 1999-2002 was followed up through 31 December 2015.

Participants

The NHANES 1999-2002 cohort included 8758 participants aged ≥ 20 years. Serum carotenoid levels were only assessed for the 1999-2000 cycle. Therefore, sample size for each assessed antioxidant ranged from 4633 to 8758.

Results

Serum vitamin E level was positively as
