Americans' use of dietary supplements that are potentially harmful in CKD.

ABSTRACT:

Background

The prevalence in the United States of dietary supplement use that may be harmful to those with chronic kidney disease (CKD) is unknown. We sought to characterize potentially harmful supplement use by individual CKD status.

Study design

Cross-sectional national survey (National Health and Nutrition Examination Survey, 1999-2008).

Setting & participants

Community-based survey of 21,169 nonpregnant noninstitutionalized US civilian adults (aged ≥20 years).

Predictor

CKD status (no CKD, at risk of CKD [presence of diabetes, hypertension, and/or cardiovascular disease], stages 1/2 [albuminuria only (albumin-creatinine ratio ≥30 mg/g)], or stages 3/4 [estimated glomerular filtration rate of 15-59 mL/min/1.73 m(2)]).

Outcome

Self-reported use of diet
