Abstract

PTC taste thresholds were determined using a modification of the Harris and Kalmus sorting technique for 854 Cumbrian schoolchildren and 699 individuals from the Isle of Man. A non-taster frequency of 19.7 percent was observed in the Cumbrian sample compared with a frequency of 27.8 per cent in that from the Isle of Man. Analysis of taste threshold distributions revealed significant variability, both within and between these two samples. Evidence of significant regional heterogeneity was detected in Cumbria but not in the Isle of Man. Finally, these two series were compared with data from neighbouring regions of the British Isles and Scandinavian populations.

摘要

采用对哈里斯和卡尔穆斯分类技术的一种改进方法，测定了854名坎布里亚郡学童和699名马恩岛人的苦味阈值。在坎布里亚郡的样本中，非尝味者的比例为19.7%，而在马恩岛的样本中这一比例为27.8%。对味觉阈值分布的分析表明，这两个样本内部和之间都存在显著差异。在坎布里亚郡检测到了显著的区域异质性证据，但在马恩岛未检测到。最后，将这两个系列的数据与不列颠群岛邻近地区和斯堪的纳维亚人群的数据进行了比较。
