Serum fibroblast growth factor-23 and risk of incident chronic kidney disease in older community-dwelling women.

ABSTRACT:

Background and objectives

Elevated circulating fibroblast growth factor 23 (FGF23) predicts progression of CKD, but it is unknown whether circulating FGF23 independently predicts incident CKD. This study aimed to determine whether circulating FGF23 predicts incident CKD in community-dwelling women.

Design, setting, participants, & measurements

This study examined the relationship of intact serum FGF23, 1,25-dihydroxyvitamin D(3) (1,25[OH](2)D), 25-hydroxyvitamin D (25[OH]D), parathyroid hormone, calcium, and phosphate with prevalent and incident CKD in 701 disabled women, ≥65 years of age, from the Women's Health and Aging Study I in Baltimore, Maryland, from 1993 to 1997. Incident CKD was defined as a low estimated GFR (eGFR) <60 ml/min per 1.73 m(2) only, low eGFR <60 ml/m
