The percentage of subjects with sleep apneic activity was significantly greater in a group of 60 healthy subjects who were 50 yr and older compared with a control group of 69 subjects who were younger than 50 yr. Sixteen of the older subjects (26.7%) and six of the younger subjects (8.7%) met the criteria for sleep apneic activity, i.e., 3-29 episodes per night. However, only one of the older subjects (1.7%) had enough sleep apneic activity (30 or more episodes in a night) to meet the definition of the condition of sleep apnea. In both age groups, sleep apneic activity (SAA) was slightly more prevalent in males than females. Older subjects with SAA were not significantly heavier than those without SAA but were so when compared with the younger subjects with SAA. In the 29 older subjects for whom hemoglobin O2 saturation (Sao2) was recorded, those with SAA had a significantly lower mean minimum Sao2 value (87%) than those without (92%).
在一组60名年龄在50岁及以上的健康受试者中，有睡眠呼吸暂停活动的受试者百分比显著高于对照组的69名年龄小于50岁的受试者。16名老年受试者（26.7%）和6名年轻受试者（8.7%）符合睡眠呼吸暂停活动的标准，即每晚3 - 29次发作。然而，只有1名老年受试者（1.7%）有足够的睡眠呼吸暂停活动（一晚30次或更多次发作）以符合睡眠呼吸暂停病症的定义。在两个年龄组中，睡眠呼吸暂停活动（SAA）在男性中比在女性中略为普遍。有SAA的老年受试者并不比没有SAA的老年受试者显著更重，但与有SAA的年轻受试者相比则更重。在记录了血红蛋白氧饱和度（Sao2）的29名老年受试者中，有SAA的受试者的平均最低Sao2值（87%）显著低于没有SAA的受试者（92%）。
