A longitudinal study of total body potassium in normal breastfed and bottle-fed infants

Abstract

In a previous publication we predicted that growth as measured by 40K is best described by comparison of the semilog function of total body potassium (TBK) vs. length with a slope that differs in infants from that of children aged 3-18 years. Data for 84 infants having three or more measurements during the first year of life attest to this hypothesis, with a regression line for TBK and length: loge K, g = -0.265 + 0.04112 length in centimeters. © 1976 International Pediatric Research Foundation, Inc.
