| Popis: | The betel-nut quid, a piece of areca nut chewed alone or mixed with tobacco and slaked lime wrapped in betel vine leaf, is widely used in Asian populations as a stimulant (due to the cholinergic agent, arecoline) or as a relaxant (due to arecaidine and guvacine).This study, which formed part of a larger project assessing the effect of energy expenditure on the duration of post-partum amenorrhoea, provided the opportunity to assess the role of chronic areca nut usage on heart rate and oxygen consumption during resting periods and during graded stepping tests.The mothers (n = 47), all of whom were lactating, were aged between 19 and 39, of low nutritional status and anaemic and they all chewed betel quid daily.Moderate users of betel quid (defined as more than 3 times a day) were found, on average, to have a significantly lower heart rate at rest and during exercise than low betel quid users (less than 3 times a day) but there was no modification in oxygen consumption.Chronic betel quid use does not seem to affect the assessment of 24h energy expenditure provided that subjects are denied access to betel nut usage before and during calibration. |
