METHODOLOGY All psychiatric patents discharged from Beijing Anding Hospital from January 1, 1991 to December 31, 1995 were studied. The annual number of patients discharged from 1991 to 1995 was 2411, 2184, 2209, 2502 and 2490 respectively, amounting to a total of 11796. Data regarding demographic data, history of psychiatric illness, family history, findings of psychiatric examinations, diagnosis, treatments and their effects were collected yearly and statistical analysis and comparison were conducted. NUMBER OF TIME DISCHARGED 60.23% (3499/11796) of patients were discharged for the first time while 19.10% (2253) were discharged for the second times. 20.85% (2428) had more than two discharges. COURSE OF ILLNESS 29.66% (3499/11796) were acute cases with the course less than one year. 25-29% (2963) were chronic case with the course lasted for 1-5 years. 16 76% (1977) had a course of 6-10 years and 28.29% (3337) over 10 years. SEX Among the patents discharged, 6288 cases were male and 5508 were female. The distribution of various diagnoses by sex is shown in Table 1. The overall male to female ratio in the five years was 1.14:1, the figure changed from 1.33:1 in 1991 to 1.02:1 in 1995. Such change corresponds to a statistically significant difference ([x.sup.2] = 20.04 and P AGE Among the sample, 8.63%(1018) of all patients were younger than 20, 58,82%(6938) from 21- 40, 27.31% (3221) from 41-60 and 5-52% (619) were over 60. As to their age of onset, 27.09% (3195) were before 20, 39.87% (4704) from 21-30, 26.79%(3160) from 31-50 and 6.25(737) from 51-60. Therefore, about 40%, of patients were young patients of age below 30 and two-thirds of them had their onset of illness before the age of 30. Within the age group of 51-60, the figure dropped from 12.78% in 1991 to 9.86% in 1995 and the corresponding figure for the group over 60 dropped from 5.93% in 1991 to 4.90% in 199, thus indicating absence of an aging tendency. Proportion of patients with their first occurrence rate between 31- 40 were 17.17%, 18.73%, 19.26% and 20.76% from 1991 to 1995 respectively. MARITAL STATUS 36.34% (4287) of discharged patients were unmarried, 56.43% (6656} were married while 5.73% (676) were separated/divorced and 1.50% (117) were widow{er)s. From 1991 to 1995, percentage of the married for the 5 years were: 59.02%, 55.68%, 54.55%, 56.91% and 55.72% from 1991 to 1995 respectively. Percentage for the divorced or seperated were: 4.19%, 5.04%, 6.88%, 6.20% and 6.34% respectively. From 1991 to 1995, the number of unmarried patients has increased by 2% and that of married patients has decreased by 49% although married patients still constituted half of the total. …
