24-hour urinary catecholamine levels have been analyzed in adults of two Tokelauan islands and in Tokelauan migrants to New Zealand.The migrants excreted greater amounts of noradrenaline and adrenaline but this is ‘offset’ by their greater excretion of creatinine. Between islands differences, however, remain in creatinine ratios and appear to reflect comparative social disruption in recent years.
