[Show abstract][Hide abstract] ABSTRACT: To identify the possible risk factors of endometriosis in Chengdu.
A hospital-based pair matched case-control study was carried out in 100 pair of female patients with endometriosis and their controls. The data were analysed by univariate analysis, multi-variate conditional logistic regression and ANOVA.
Univariate analysis showed that the positive response rates for "high educational level, history of ectopic pregnancy, short menstrual cycle, menorrhagia, dysmenorrhea, not warmly dressed during menses, depression, history of coitus during menstruation or puerperium and heavy pungent food" in the endometriosis group were much higher than those in the control group (P < 0.05). The multivariate analysis confirmed that the risk factors associated with endometriosis were menorrhagia, not warmly dressed during menses, depression during menstruation, heavy pungent food, and history of ectopic pregnancy (OR = 0.388, 3.066, 4.292, 2.742, 3.612, respectively).
The above findings suggest that endometriosis may be associated with menorrhagia, negligence in menstrual hygiene, and certain behavioral and psychological factors.

[Show abstract][Hide abstract] ABSTRACT: To investigate the situation of reproductive health of perimenopausal and postmenopausal women in Chengdu and provide a basis for planning reproductive health care for these women.
We conducted a population-based cross-sectional study in women who were over 45 years old in the central city and the nearby county of Chengdu.
The mean age of menopause was 48.1 years. There were sixty percent of women who had dysfunctional uterine bleeding before menopause. About half of the postmenopausal women had experienced perimenopausal symptoms. There were 460 women who ever used or currently use estrogen therapy. But only half of them visited doctors and sought medical therapy. And the main problems were hot flash, night sweats, dyssomnia, and urinary infection. Most of them took medicine for a short period (< 1 year).
We found that middle-aged and older women have many symptoms related to menopause. It is necessary for us to provide reproductive health care for them.

[Show abstract][Hide abstract] ABSTRACT: The database from Chinese Birth Defects Monitoring Network was used to describe the epidemiological features and secular trends of neural tube defects (NTDs) prevalence during Jan. 1996 to Dec. 2000, including anencephaly, spina bifida and encephalocele.
Data were collected with hospital-based cluster sampling method. During the period, all live or still births with 28 weeks or more of gestation were assessed within seven days after delivery.
There were 2 873 case with NTDs identified from 2 281 616 births, with an overall prevalence rate of 12.95 per 10,000 births. And, the prevalence rates of anencephaly, spina bifida and encephalocele were 5.02 per 10,000, 6.30 per 10,000 and 1.64 per 10,000, respectively. Significant falls in overall prevalence rates of NTDs and of anencephaly were observed. The prevalence rates of NTDs were 9.75 per 10,000 and 15.96 per 10,000 in male and female births, respectively, 7.76 per 10,000 and 25.20 per 10,000 in the urban and rural areas, respectively, and 19.90 per 10,000 and 5.81 per 10,000 in north and south China, respectively. The prevalence was higher in the groups with maternal age of less than 20 years and more than 30 years than in those other maternal ages. Preterm babies and babies with low birth weight accounted for 50.9% and 50.6% of perinatal babies with NTDs, respectively, with a perinatal mortality of 77.8%.
In China, the occurrence of NTDs was higher in female births than in male births, higher in the rural than in the urban, and higher in the north than in the south. Annual prevalence rate of NTDs in China presented a declining trend, but still higher than that in the other countries at the same time period. Babies with NTDs were in poor birth quality, higher perinatal mortality and poor prognosis. Effective preventive measures and prenatal diagnosis should be strengthened to reduce the occurrences of neural tube defects.

[Show abstract][Hide abstract] ABSTRACT: To investigate the prevalence rate and epidemiological features of teratomas in China.
From 1987 through 1992, hospital-based cluster sampling method was adopted for collecting data. During that period all live or still births with 28 weeks of gestation or more were assessed within 7 days after delivery.
238 teratoma cases were identified in 4,489,692 births, including 198 isolated and 40 associated forms of teratomas. The prevalence rates of total teratomas, isolated and associated forms of teratomas were 0. 53/10000, 0.44/10000, 0.09/10000 respectively. The prevalence rates in urban areas and rural areas were 0.46/10000 and 0.66/10000, respectively. The prevalence rates of teratomas in male and female births were 0.80/10000 and 0.27/10000 correspondingly. The ratio of male to female teratomas was 1:2.76. The perinatal fatality rate of teratomas was 55.0%.
The most frequent teratomas were isolated forms. Time trends have not been found in the occurrence of teratomas. High prevalence in urban areas has been observed, compared to that in rural areas. The prevalence of teratomas in female births is three times as high as that in male births. In view of the high fatality rate, prenatal diagnosis and perinatal management of teratomas should be strengthened.
