ABSTRACT
Objective @#To analyze the characteristics of HIV/AIDS cases with non-marital or non-commercial heterosexual transmission in Hangzhou, and the influencing factors for new infection and local infection, so as to provide the evidence for AIDS prevention and control.@*Methods @#From 2017 to 2019, the newly reported HIV/AIDS cases with non-marital or non-commercial heterosexual transmission in Hangzhou were recruited, and their demographic information, previous sexual behaviors and history of HIV testing were collected in the questionnaire survey. The multivariate logistic regression model was used to analyze the influencing factors for new infections and local infections. @*Results @#A total of 522 participants from 668 newly reported HIV/AIDS cases with non-marital or non-commercial heterosexual transmission in Hangzhou during this period were surveyed．Among 522 cases, 263 ( 50.38% ) were aged 40 years or above, 218 ( 41.76% ) were married, 326 ( 62.45% ) had an educational level of junior high school or below, and 340 ( 65.13% ) were not local. Among 504 cases whose infection time could be determined, 72 ( 14.29% ) were newly infected within one year; age of 40 years below ( OR=4.148, 95%CI: 1.956-8.795 ), history of HIV testing ( OR=2.049, 95%CI: 1.163-3.609 ) and history of sexually transmitted diseases ( OR=2.169, 95%CI: 1.076-4.374 ) were risk factors for new infection. Among 454 cases whose infection location could be determined, 267 ( 58.81% ) were infected in Hangzhou; educational level of high school or below ( OR=2.538, 95%CI: 1.252-5.145 ) , Hangzhou residence ( OR=7.835, 95%CI: 4.227-14.353 ), living in Hangzhou for a year or over ( OR=18.960, 95%CI: 8.755-41.060 ) and monthly income of 3 000 yuan or over ( OR=2.630, 95%CI: 1.546-4.474 ) were risk factors for local infection. @*Conclusions @#The HIV/AIDS cases with non-marital or non-commercial heterosexual transmission in Hangzhou are mainly floating population and less educated. The newly infected cases are more likely to be young and middle-aged people and patients with sexually transmitted diseases, the locally infected cases are more likely to be people with permanent residence, less educated and high income.
ABSTRACT
Objective To describe the characteristics of newly reported HIV/AIDS cases via non-marital or non-commercial heterosexual transmission and to find out the relative factors in Hangzhou,from 2015 to 2017.Methods Data were collected through the national HIV/AIDS comprehensive control and prevention data system.Study subjects would include those reported HIV/AIDS cases who were residents of Hangzhou and were infected via non-marital heterosexual transmission,between January 1,2015 and December 31,2017.Demographic characteristics and behavioral information were collected.x2 test was used to compare different characteristics of the non-married heterosexual transmission subjects.Logistic regression was used to assess factors that associated with non-marital but non-commercial HIV heterosexual transmission with SPSS.20 software used to analyze statistically.Results Non-marital HIV heterosexual transmission accounted for 38.03％ (1 393/3 663) of the total new reported HIV/AIDS cases in 2015-2017.Out of the 1 393 HIV/AIDS cases,those infected through non-marital but non-commercial heterosexual transmission accounted for 50.83％ (708/1 393),and those through non-martial commercial transmission was accounted for 49.17％ (685/1 393).Male to female ratio was 3.51 ∶ 1 (1 084/309).Male HIV cases reported that their major way of infection was via non-marital commercial transmission (670/1 084,61.81％),while female patients reported the way was via non-marital non-commercial (294/309,95.1％).Results from multivariate logistic analysis showed that the related risk factors and ORs for non-marital but non-commercial transmission appeared as:female (aOR=48.25,95％ CI:26.94-88.44),＜30 year olds (aOR=2.43,95％CI:1.3 1-4.5 1),30-39 year olds (aOR=1.92,95％CI:1.11-3.33),40-49 year olds (aOR=1.80,95％ CI:1.08-3.00),married or unmarried (vs.divorced or widowed,aOR=1.57,95％CI:1.10-2.24;aOR=1.78,95％CI:1.15-2.78),high school and above of education level (vs.primary school and under of education level,aOR=1.82,95％ CI:1.18-2.80),administrative officers or employee (vs.farmers,aOR=2.03,95％ CI:1.04-l.91).Number of non-marital partners less than 5 (vs.number of non-marital partners more than 5,aOR=10.65,95％CI:6.41-17.42).Conclusions HIV/AIDS cases with non-marital heterosexual transmission accounted for considerable proportion regarding the HIV transmission in Hangzhou from 2015 to 2017.Differences were found in the following factors as non-marital and non-commercial heterosexual transmission with diverse gender,age,marital status,educational level and occupation among of the HIV/AIDS patients.

ABSTRACT
Objective@#The goal of this research was to understand the demographic distribution and related factors of non-marital and non-commercial heterosexual transmission (non-commercial transmission) for HIV/AIDS (human immunodeficiency virus/acquired immunodeficiency syndrome).@*Methods@#Data related to HIV/AIDS infected by non-marital heterosexual transmission and whose present address was in Qian Dongnan, were collected from Information System on the HIV/AIDS Prevention and Control. Information included demographic characteristics, the members of non-marital sex partners, transmission path, detection source, CD4+T lymphocyte level, et al. cases belong to homosexual history, injective drug use or non-classified non-marital heterosexuality transmission were excluded, totally collect HIV/AIDS 919 cases. Multivariate logistic regressions were used to analyze potential factors associated with non-marital and non-commercial heterosexual transmission. In addition, in March and June 2017, using a convenience sampling, we conducted one-to-one interviews among 10 HIV/AIDS who were infected by non-marital heterosexuality and had non-marital and non-commercial heterosexual experience in Kaili Center for Disease Control and Prevention. The content of the interview included basic information, sexual orientation, the main place of making friends and sexual behavior, attitude to commercial heterosexuality and non-martial and non-commercial heterosexuality and so on.@*Results@#Out of the 919 cases, 645 (70.2%) were male, the proportion of non-commercial transmission was 55.06% (506). The proportion of female HIV/AIDS with non-commercial transmission was 84.7% (232), which was higher than male (42.5%(274)) (χ2=138.35, P<0.001). The proportion of Han HIV/AIDS with non-commercial transmission was 61.5% (275), which was higher than other religion (52.2%(412)) (χ2=6.32, P=0.012). The proportion of HIV/AIDS with non-commercial transmission who had 0-5 non-marital sexual partners was 58.8% (498), which was higher than who had>5 non-marital sexual partners (11.1%(8)) (χ2=61.10, P<0.001). The proportion of HIV/AIDS with non-commercial transmission who lived mobile was 72.9% (94), which was higher than who lived fixedly (52.2%(412)) (χ2=19.34, P<0.001). Qualitative interviews results revealed that the age of the respondents were 22-69. Respondents whose ages are in 22-34 were more likely to use mobile phone (4/10) and respondents whose ages are in 35-69 were less likely to look partners through party and the context of working.@*Conclusion@#The proportion of cases being infected by non-marital and non-commercial heterosexual transmission in Qian dongnan was higher than general national levels. The characteristics of sex, marriage status, migration, vocation, the members of non-marital sex partners were significant differed between commercial heterosexual transmission and non-marital and non-commercial heterosexual transmission.
ABSTRACT
Objective To understand the epidemiological characteristics and changing patterns of HIV transmission through heterosexual contact since 2008,and to project the influences of heterosexual transmission mode on the HIV epidemic in China.Methods Demographic data and history of exposure in newly identified HIV/AIDS cases aged 15 years or older,through heterosexual transmission mode from 2008 to 2014,were collected and analyzed.Results The number of HIV/AIDS cases caused by heterosexual transmission increased from 23 402 in 2008,to 68 671 in 2014.The proportion of heterosexual transmission mode increased from 8.7％ in 2008 to 66.4％ in 2014.Among these cases,the proportion of males increased from 55.3％ in 2008 to 68.2％ in 2014.Among those who reported acquiring HIV through heterosexual contact,the proportion of cases through extra-marital sexual acts out of all the newly report ones,increased from 78.2％ in 2008 to 88.2％ in 2014.This mode of infection accounted for 85.2％ in the age 15 to 49 years group,comparing to 84.2％ in the age group of 50 years old or above.The proportion of reported HIV infections through extra-marital sexual acts appeared 93.8％ on males while 69.0％ on females,with statistically significant difference (x2=36 000.000,P＜0.001).Conclusion As the predominant factor of HIV/AIDS epidemic,currently in China,heterosexual transmission showed diversities in different sub-epidemic areas,gender or age groups.Tailored strategies were urgently needed for health education and high-risk behavioral intervention,according to the local epidemic driven factors,respectively.
ABSTRACT
OBJECTIVES: Despite the importance of human immunodefi-ciency virus(HIV) transmission through heterosexual contact, the features of heterosexual transmission has not been well studied in Korea. So we conducted a cross sectional study to determine the transmission rates in married couples and assess risk factors for male to female heterosexual transmission of HIV. METHODS: 169 HIV-infected males and their female sex partners were recruited from 1985 to June 1998. We examined female sex partners HIV infection status and interviewed male index partners and their female sex partners about demographic characteristics and sexual practices. We analysed heterosexual transmission rate by epidemiologic characteristics, disease status and sexual practices. And we assessed risk factors for HIV infection by univariate and multivariate analysis. RESULTS: 30 female sex partners were infected at enrollment, yielding an transmission rate of 17.8%. Among couples who had used condoms consistently, none of the female sex partners was infected with HIV. In univariate analysis the significant risk factors were full blown AIDS status (OR=4.1, 95% CI: 1.49-11.43) and low CD4 T cell count of index partners at enrollment (OR=7.8, 95% CI: 2.19-27.80). In multivariate analysis HIV-1 RNA levels was significant risk factor when adjusted by CD4 T cell counts and mean sexual contacts per month (OR=19.2, 95% CI: 1.03-357.59) CONCLUSION: The risk of male to female heterosexual transmission increased with advanced stages of HIV infection in the index male partners.

Este trabajo presenta un análisis de evolución de los casos de SIDA y la seroprevalencia de infección por VIH en mujeres de México, desde el inicio de la epidemia hasta el primer semestre de 1994, así como de los factores sociales y culturales que ponen en particular desventaja a la mujer mexicana respecto de la adopción de medidas preventivas de esta enfermedad. Desde 1985 en que se presentaron los primeros casos de SIDA en mujeres y hasta el 1 de junio de 1994, se había acumulado un total de 2 767 casos de SIDA en mujeres, que corresponden al 14.8 por ciento del total acumulado. Los primeros casos se asociaron a transfusiones de sangre contaminada; sin embargo, a partir de 1986 empezaron a aparecer casos asociados a transmisión heterosexual. Actualmente, sólo el 35 por ciento de los casos nuevos de SIDA reportados en mujeres son atribuibles a transfusiones, mientras que el 64 por ciento corresponde a transmisión sexual, coexistiendo dos epidemias: la de transmisión sanguínea, con una velocidad de duplicación de 45 meses y una tendencia hacia la disminución, y la transmitida por contacto sexual, que presenta una mayor velocidad de crecimiento (periodo de duplicación de meses) y cuya tendencia es ascendente. En general la mujer presenta mayor vulnerabilidad, tanto biológica como social y cultural, a la transmisión del VIH/SIDA. Las condiciones de desigualdad económica, social y cultural de las mujeres respecto de sus parejas sexuales, desemboca en relaciones de dependencia y falta de poder social desde las cuales es muy difícil evaluar objetivamente el riesgo de infectarse y, aún más, negociar la adopción de medidas preventivas. En situación particularmente desventajosa se encuentran las mujeres de áreas rurales, a lo cual se agrega la tendencia a la ruralización de la epidemia asociada a la migración interna y sobre todo internacional (de trabajadores temporales hacia los EUA), que puede resultar en efectos demográficos y sociales de gran impacto. Se concluye que es necesario profundizar en el diseño y evaluación de estrategias de prevención bajo control de las mujeres que les permitan protegerse, aun sin el conocimiento de su pareja sexual; simultáneamente deben realizarse estrategias educativas dirigidas a parejas heterosexuales (especialmente jóvenes), que les permitan negociar la adopción de medidas preventivas eficaces
This study presents an analysis of AIDS cases and seroprevalence of HIV infection among Mexican women, from the onset of the epidemic through June 1994, as well as the analysis of the social and cultural factors that put women in a powerless situation regarding the adoption of preventive measures. Since 1985, when the first AIDS cases among women were reported in Mexico and until June 1, 1994, a total of 2 767 cases have been reported, representing 14.8% of the total number of cases. The first cases of AIDS among women were associated to infected blood transfusions; however, in 1986, heterosexually transmitted cases began to appear. Currently, only 35% of newly reported AIDS cases are associated to blood transfusions while 64% of them are related to heterosexual transmission. In fact, two epidemics are evident: one transmitted through blood, showing a downward trend (duplication time 45 months), and a second one, heterosexually transmitted, increasing twice as fast (duplication time 27 months). The latter is expected to dominate AIDS epidemiology among women in the future. In general, women are more vulnerable to HIV/AIDS biologically, but also socially and culturally. Women is economic, social and cultural subordination to their sexual partners results in a situation that makes it difficult for them to assess their infection risk and even more, to negotiate taking preventive measures. This situation is even more disadvantageous to rural women and, together with the recent trend of the AIDS epidemic to ruralization and with internal and international migration (temporary work force migration to the USA), can result in deep demographic and social effects. We conclude that it is necessary to work on the design and assessment of preventive measures under women's control, that empower them to protect themselves even without their partner's awareness. Also, it is necessary to promote sexual education among young heterosexual couples on how to talk about sexual issues and negotiate the use of preventive measure according to their actual sexual practices.
