本文对1955名5-99岁儿童的辨认能力进行了测定。平均而言，女性在所有年龄段的表现都优于男性，不吸烟者的表现优于吸烟者。峰值性能出现在第3至第5个十年，并在第7个十年后显着下降。超过一半的65-80岁的老年人表现出严重的嗅觉障碍。80年后，> 3/4的患者出现严重损伤。鉴于这些发现。难怪不少长者投诉食物味道欠佳，而每年意外气体中毒个案中，长者占了不成比例的比例。
Smell identification ability was measured in 1955 persons ranging in age from 5-99 yr. On the average, women outperformed men at all ages and nonsmokers outperformed smokers. Peak performance occurred in the 3rd through 5th decades and declined markedly after the 7th. More than half of those 65-80 yr old evidenced major olfactory impairment. After 80 yr, > 3/4 evidenced major impairment. Given these findings. it is not surprising that many elderly persons complain that food lacks flavor and that the elderly account for a disproportionate number of accidental gas poisoning cases each year.
