title: STD epidemiologic analysis at national surveillance spots in the period 1987-1990.
abstract: This article summarizes surveillance data of STDs at 16 urban monitoring centers in 1987-1990. During the four year period, 125,493 STD cases were reported. The average annual incidence was 77.80/100,000. Because the rate of increase in females (65.85% per year) was greater than that in males (36.81% per year), the male-to-female ratio fell from 2.39:1 (1987) to 1.34:1 (1990). The number of STD cases reported from all centers tended to increase, and the overall rate of increase was 46.61% per year. The major disease was gonorrhea, with a constituent ratio of 59.22% (1990). However, condyloma acuminatum and nongonococcal urethritis had greater rates of increase (105.03% and 85.14% per year, respectively). The 20-39 year age group accounted for 82.10% of total cases, for STD patients were mostly in the sexually active population. The STD incidence among self-employed businessmen (1206.06/100,000, in 1990) was highest among professional populations. According to analysis of different regions, STD incidence was highest in the southern cities (203.00/100,000, 1990). The greatest rate of increase of STDs was in Yangtze River Valley cities, where the average annual rate of increase was 71.41%.
