A questionnaire study was carried out among elderly subjects (mean age 73.6 +/- 6.1 years (SD)) with a response rate of 74% (n = 1,115). It covered various aspects of health, symptoms and disease. 26% (n = 287) stated that they had two or more micturitions per night. A subgroup consisting of healthy older people, 39 men and 56 women with an average age of 73.9 +/- 4.9 years and 70.8 +/- 5.3 years, respectively, was studied concerning the distribution of diuresis and the frequency of voiding. The combined 24-hour diuresis (average for three 24-hour periods) was 1,400-1,600 ml, with a quotient between day and night of about 1, except the group with only one micturition at night (12 hours), where it was 1.8. The micturition volume between 08-20 h was less than between 20-08 h. The micturition volumes during both periods were significantly less with an increase in the number of voidings between 20-08 h. The quotient between the micturition volume 08-20 h and 20-08 h was strikingly constant (about 0.7). The finding of equally large urine volumes both day and night differs from that among younger adults in whom the diuresis is twice as large in the day as in the night.
对老年受试者（平均年龄73.6±6.1岁（标准差））进行了问卷调查研究，应答率为74%（n = 1115）。该研究涵盖了健康、症状和疾病的各个方面。26%（n = 287）的人表示他们每晚排尿两次或更多次。对一个由健康老年人组成的亚组进行了研究，该亚组包括39名男性和56名女性，平均年龄分别为73.9±4.9岁和70.8±5.3岁，研究内容包括利尿分布和排尿频率。24小时联合尿量（三个24小时时间段的平均值）为1400 - 1600毫升，白天与夜间的比值约为1，但夜间仅排尿一次（12小时）的组该比值为1.8。08 - 20时的排尿量少于20 - 08时。在这两个时间段内，随着20 - 08时排尿次数的增加，排尿量均显著减少。08 - 20时与20 - 08时排尿量的比值非常恒定（约为0.7）。白天和夜间尿量同样多的这一发现与年轻成年人不同，年轻成年人白天的尿量是夜间的两倍。
