Population-based study on infection and genotype distribution of high-risk human among women in rural areas of China, 2014 / 中华预防医学杂志

Objective@#To explore the epidemiologic characterization of high-risk human papillomavirus (HR-HPV) infection and genotype distribution of HR-HPV among women in rural areas of China.@*Methods@#This study used multiple layers of stratified cluster random sampling method. During January to December in 2014, 117 counties of 27 provinces were selected as the HPV test screening pilot project counties. The women aged 35-64 years with rural areas Hukou in these project counties were selected as the study subjects. A total 457 799 women received HPV DNA test. Among them, 118 237 women from 32 counties in 11 provinces received qualified HPV DNA test by fluorescent PCR to detect HPV genotypes.@*Results@#Among 118 237 rural women, the overall HR-HPV positive infection rate was 7.8% (9 249/118 237). The infection rate increased with age and reached an infection peak at the 60-64 age groups (9.9%, 831/8 394). The HR-HPV positive infection rate in western regions (6.9%, 2 144/31 130) was statistical significantly lower than in central regions (8.2%, 1 894/23 023) and eastern regions (8.1%, 5 211/64 084) (χ2=51.46, P<0.001). Among 9 249 women with specific genotypes of HR-HPV, 6 496 (97.6%) cases were infected with single HR-HPV type, and 163 cases (2.4% ) were infected with multiple types. HR-HPV type 52, 16 and 58 were the most common infection types in rural areas of China. The single infection rates were 20.9% (1 355/6 496), 18.7% (1 215/6 496), and 11.2% (725/6 496), respectively. The multiple infection rates were 47.2% (77/163), 17.8% (29/163), and 18.4% (30/163), respectively.@*Conclusion@#The HR-HPV positive infection rate in rural areas of Chinese woman was 7.8%, western region has lower infection rate compared with central and eastern regions. HPV 52 was first of the most common genotypes in rural areas of China.

Occurrence of cesarean section and related factors in 40 counties of China from 1978 to 2010 / 中华预防医学杂志

<p><b>OBJECTIVE</b>To find out the occurrence of cesarean section (CS) and related factors among child-bearing women in China.</p><p><b>METHODS</b>The survey was conducted during October, 2010 in 40 counties selected from 30 provinces. Size proportional sampling method was employed in sampling. A face to face questionnaire investigation was conducted among 8 420 women who experienced pregnancies from 1978 to 2010. Information on demographic characteristics, history of pregnancy and birth were obtained, and related factors of CS occurrence were analyzed.</p><p><b>RESULTS</b>A total of 11 440 living births have been given by 8 420 women, and 1 725 CS happened. As the time goes on, there is a growing trend of CS occurrence, from 2.0% (14/701) in 1978-1985 to 36.6% (813/2 224) in 2006-2010, and there is a most fast increase from 2001 to 2010. CS rate in Mid-China (42.3%, 257/608) is the highest from 2006 to 2010. And also, the rate of CS requested by the pregnant women or their family members was increasing year by year, from 14.3% (2/14) in 1978-1985 to 43.7% (255/813) in 2006-2010. Women who were above 25 years old (21.4%, 960/4 485) , with an education degree of high school or above (24.5%, 568/2 317), engaged in nonagricultural work (22.4%, 663/2 956), living in eastern provinces of China (18.6%, 757/4 074), fetal malposition (45.4%, 247/544) , with a heavier birth weight(4 000 gram or above) (36.5%, 175/479) , have accepted B ultrasound exam (18.8%, 1 633/8 687) with an increasing of blood pressure (28.0%, 172/614) and convulsion experiences (24.8%, 131/528) during pregnancy were more likely to have CS.</p><p><b>CONCLUSION</b>The CS rate among child-bearing women in China was rather high, and was related with factors of demographic characteristics(age of childbearing, education, vocation, residence) and some medical factors(neonatal weight, having accepted B ultrasound exam, fetal malposition, an increase of blood pressure and convulsions during pregnancy).</p>

Contraceptive use behavior among never married young women who are seeking pregnancy termination in Beijing / 中华医学杂志(英文版)

<p><b>OBJECTIVE</b>To identify contraceptive use behavior and its determinants among never married young women with an unwanted pregnancy and seeking pregnancy termination in Beijing.</p><p><b>METHODS</b>A cross sectional study, adopting the Lawrence' PRECEDE-PROCEED model was conducted in 1999 in Beijing, China. A total of 306 unmarried young women, aged 18 to 24 years and requesting pregnancy termination, were face to face interviewed.</p><p><b>RESULTS</b>Only 13% of the young women insisted on contraceptive use, and almost an equal proportion occasionally or never used contraceptives (26% and 27%, respectively). Among 224 women who had contraceptive use during the past 12 months, the methods used most often were condom (49%), withdrawal (28%) and the rhythm method (16%). One of the most important reasons cited by 73 percent of women who had never used contraceptives was that they did not realize the risk of getting pregnant. The results of logistic regression analysis revealed that knowledge on contraception, boyfriend's approval of contraceptive use, perceived risk of getting pregnant, perceived availability of contraceptive services and discussion of contraception with boyfriend were important indicators of a young woman's contraceptive use behavior.</p><p><b>CONCLUSION</b>These results indicate an urgent need to develop sex education on conception and contraception among young women and men. It is equally important to enhance young women's perception about the risk of unwanted pregnancy and the complications of induced abortion. Promotinga men's cooperation and participation in contraceptive use as well as strengthening communication on contraception between young women and their partners is essential.</p>
