Inter-population comparisons of urinary catecholamines: a pilot study

Abstract
Urinary catecholamine excretion rates, previously related to lifestyles and environmental influences, were investigated in 3 traditional-living populations and in an English population. Significant inter-population differences in excretion rates and in creatinine-related excretion were observed. These included high daytime levels of adrenaline [epinephrine] output in the traditional groups relative to the English group. Methodological problems are discussed.
