Study on genital tract Chlamydia trachomatis and gonococcal infection in Han and minority (Naxi and Dai) women in China's two provinces.
OBJECTIVE
To estimate the prevalence of lower female genital tract chlamydial (GTC) and gonococcal infection in 3 different ethnic groups in China, and to analyze the risk factors influencing these infections.


METHODS
A cross-sectional survey + physical and laboratory examinations. 1,800 married women aged 18-35 Han (600, from Dujiangyan city, Sichuan), Naxi (600, from Yanyuan county, Sichuan), and Dai (600, from Jinghong Prefecture, Yunnan) were investigated between March 1996 to March 1997. Information was obtained about their personal history, socioeconomic status, medical history, STDs, sexual history, contraceptive history, results of both examinations. Tabulation, t-test, Chi-square test, multiple-logistic models were used to analyze the data.


RESULTS
3.2% of Han, 12.8% of Naxi and 4.5% of Dai women tested positive for gonococci; and 9.1% of Han, 16.7% of Naxi and 27.5% of Dai women tested positive for GTC infection. The differences of GTC and gonococcal infections between Han and Naxi, and Han and Dai women were significant.


CONCLUSIONS
STDs are common in China today; both GTC and gonoccocal infections are related to non-use of condom, having sexual partners other than husband, number of abortions, and low education; and condom has a function in prevention of STDs.
