Abstract

Twenty-two women. and 12 men collected 24-hr urine samples under free-living conditions. The study was conducted to determine the variationin urinary catecholamine excretion between and within subjects, as well as rite impact of alcohol alcohol consumption on this variation. Subjects were fed controlled diets (20% or 40% of energy from fat) for two 8-week periods; within each dietary group, subjects consumed a carrier beverage with ethanol (5% of daily energy intake) during one 8-week period. Urine samples were collected during week 5 of each period for 4 consecutive days and analyzed for epinephrine, norepinephrine, anddopamine by HPLC with electrochemical detection. There was no significant effect due to dietary fat on catecholamines excretion; therefore,all subjects were combined. Coefficients of variation were determinedseparately for men and women and for alcohol consumption within sex. Daily excretion of epinephrine and norepinephrine was significantly greater (P < 0.01) in men than in women. Within- and between-subject variability presented large coefficients of variation for both men (28-48%) and women (22-47%). Although within-subject variation was similar for men and women, between-subject variation was consistently greater for women than for merr regardless of alcohol consumption or abstention. Alcohol consumption did not significantly affect the levels of urinary catecholamine excretion within sex. However, bath within- and between-subject variation decreased during alcohol consumption in all subjects. (J. Nutr. Biochem. 9:396-401, 1998) Published by Elsevier ScienceInc. 1998.
