Conducta infiel y adicción a redes sociales en adultos de la selva peruana / Unfaithful behavior and addiction to social networks in adults from the Peruvian jungle

La adicción a las redes sociales potencia las probabilidades de infidelidad de pareja. Esta investi-gación tuvo el objetivo de determinar la relación entre conducta infiel y adicción a redes sociales en adultos de las áreas comerciales de Tarapoto, Lamas, San José de Sisa, Moyobamba y Naran-jos, región de la Amazonía Peruana, durante el primer cuatrimestre de 2021. Así, se desarrolló un estudio con diseño no experimental y tipo de investigación correlacional, en una muestra de 318 individuos con edades entre 20 y 40 años, a los que se aplicó el Inventario Multidimensional de Infidelidad y el Cuestionario de Adicción a Redes Sociales. El 62,3% de los participantes perteneció al sexo masculino, el 57,5% tenía edades entre 30 y 59 años, el 66,7% convivía con sus parejas sin estar casados y el 51,6% se encontraban en la segunda etapa de la relación de pareja. Existieron diferencias significativas entre hombres y mujeres en cuanto a la conducta infiel (U=6387,500; p<0,000). En este contexto, se observó un predominio del nivel medio de la adición a las redes sociales en los participantes y del bajo en las dimensiones de la conducta de infidelidad, estableciéndose correlación estadísticamente significativa entre ambas variables.

Addiction to social networks increases the chances of partner infidelity. This research aimed to determine the relationship between unfaithful behavior and addiction to social networks in adults from the commercial areas of Tarapoto, Lamas, San José de Sisa, Moyobamba, and Naranjos, in the Peruvian Amazon region, during the first four-month period of 2021. Thus, a study with a non-experimental design and correlational research type was developed in a sample of 318 individuals between 20 and 40 years old. The Multidimensional Infidelity Inventory and the Social Networks Addiction Questionnaire were applied. 62.3% of the participants were male, 57.5% were between 30 and 59 years old, 66.7% lived with their partners without marria-ge, and 51.6% were in the second stage of the couple relationship. There were significant diffe-rences between men and women regarding unfaithful behavior (U=6387,500; p<0.000). In this context, a predominance of the medium level of addiction to social networks in the participants and the low level in the dimensions of infidelity behavior were observed, establishing a statisti-cally significant correlation between both variables.

Se concluye que por ser más liberales sexualmente, los hombres son más propensos a contraer una enfermedad de transmisión sexual.(AU)

Fatores associados ao uso inconsistente de preservativo com parceiros comerciais entre homens que fazem sexo com homens no Brasil / Factors associated with inconsistent condom use among men who have sex with men in Brazil and their commercial sexual partners / Factores asociados al uso inconsistente del preservativo con las parejas comerciales entre los hombres que tienen sexo con hombres en Brasil

O objetivo foi analisar os fatores associados ao uso inconsistente de preservativo com parceiros comerciais entre homens que fazem sexo com homens (HSH) no Brasil. Foi feito um estudo transversal, com HSH adultos, recrutados por meio da técnica respondent-driven sampling (RDS), em 12 capitais brasileiras, em 2016. Os HSH responderam a um questionário sociocomportamental, que incluía questões sobre o comportamento sexual. O uso inconsistente de preservativo com parceiros comerciais foi mensurado por meio das relações sexuais anais insertivas e receptivas, ocorridas nos últimos seis meses e na última relação sexual. A associação entre as variáveis independentes e o uso inconsistente de preservativo foi mensurada utilizando o modelo de regressão de Poisson com variância robusta, com estimação de razões de prevalência ajustadas (RPa). Foram analisados dados de 461 HSH. A prevalência de uso inconsistente de preservativo com parceiros comerciais foi de 26% (IC95%: 19,0-34,3, n = 123). Pertencer às classes econômicas mais baixas (D/E), ter médio ou baixo conhecimento sobre HIV, ter praticado sexo anal insertivo e receptivo e nunca ter realizado teste para HIV na vida são fatores que estiveram associados ao uso inconsistente de preservativo com parceiros comerciais. As variáveis associadas ao uso inconsistente indicaram que o sexo comercial está sendo praticado em um contexto de maior vulnerabilidade à infecção pelo HIV. Nesse sentido, são necessárias intervenções biomédicas e comportamentais, com foco no acesso e na utilização de estratégias de prevenção, aliadas a políticas públicas para a redução de desigualdades socioeconômicas entre HSH que praticam sexo comercial.

We aimed to analyze the factors associated with inconsistent condom use among men who have sex with men (MSM) and their commercial sexual partners in Brazil. This is a cross-sectional study with adult MSM who were recruited via respondent-driven sampling (RDS) in 12 Brazilian capitals in 2016. MSM answered a sociobehavioral questionnaire which included questions on their sexual behavior. The inconsistent use of condoms with their clientele was measured via insertive and receptive anal sex in the six months prior to our research and in their last sexual intercourse. The association between independent variables and the inconsistent use of condoms was measured via a Poisson regression model with robust variance and estimation of adjusted prevalence ratios (aPR). Data from 461 MSM were analyzed. We found a 26% prevalence of inconsistent condom use with their clientele (95%CI: 19.0-34.3, n = 123). Belonging to the lowest economic classes (D/E), having medium or low knowledge about HIV, having practiced insertive and receptive anal sex, and having never tested for HIV throughout their lives were associated with inconsistent use of condoms with their clientele. The variables associated with inconsistent use indicated that commercial sex is practiced in a context of greater vulnerability to HIV infection, referring to the need for biomedical and behavioral interventions which focus on access to and use of prevention strategies together with public policies to reduce socioeconomic inequalities among MSM who practice commercial sexual.

Estudio transversal, con HSH adultos, reclutados a través de la técnica respondent-driven sampling (RDS), en 12 capitales brasileñas, en 2016. Los HSH respondieron a un cuestionario sociocomportamental que incluía preguntas sobre el comportamiento sexual. El uso inconsistente del preservativo con parejas comerciales se midió por las relaciones anales insertivas y receptivas que se produjeron en los últimos seis meses y por la última relación sexual. La asociación entre las variables independientes y el uso inconsistente del preservativo se midió mediante el modelo de regresión de Poisson con varianza robusta, con estimación de las razones de prevalencia ajustadas (RPa). Se analizaron los datos de 461 HSH. La prevalencia del uso inconsistente del preservativo con las parejas comerciales fue del 26% (IC95%: 19,0-34,3, n = 123). Pertenecer a las clases económicas más bajas (D/E), tener un conocimiento medio o bajo sobre el VIH, haber practicado sexo anal tanto insertivo como receptivo y no haberse sometido nunca a la prueba del VIH en su vida se asociaron con el uso inconsistente del preservativo con las parejas comerciales. Las variables asociadas al uso inconsistente indicaron que el sexo comercial se está practicando en un contexto de mayor vulnerabilidad a la infección por el VIH, refiriendo la necesidad de intervenciones biomédicas y conductuales, con un enfoque en el acceso y uso de estrategias de prevención, junto con políticas públicas para reducir las desigualdades socioeconómicas entre los HSH que practican el sexo comercial.

Young women born with HIV: communication of seropositivity to partners / Young women born with HIV: communication of seropositivity to partners

RESUMO Objetivou-se compreender os aspectos envolvidos na comunicação da própria condição clínica aos parceiros por mulheres jovens que nasceram com HIV. Trata-se de pesquisa qualitativa, desenvolvida em Serviço de Assistência Especializada ao HIV na região sul do Brasil com dez jovens que nasceram com HIV, sendo empregada a entrevista individual, de junho de 2017 a março de 2018. Utilizou-se a análise psicossocial ancorada no Quadro da Vulnerabilidade e dos Direitos Humanos. Evidenciaramse dois grupos: o primeiro, composto por jovens que optaram por comunicar sua condição clínica ao parceiro no início das relações afetivas; e o segundo, com as jovens que postergaram tal comunicação. Todas vivenciaram receios e medos da reação do parceiro, pensaram ou adotaram algumas estratégias para a comunicação e relataram situações de menor implicação nas condutas preventivas ao HIV pelos casais/parceiros. Conclui-se que são essenciais práticas de cuidado que dialoguem com as jovens sobre as dificuldades singulares em seus contextos intersubjetivos, atravessados por questões sociais estruturais a fim de apoiá-las na comunicação sobre a soropositividade aos parceiros em tempo mais oportuno possível, na adoção de estratégias preventivas e no acesso aos recursos que protejam a saúde sexual e reprodutiva delas e dos parceiros.

ABSTRACT The objective was to understand the aspects involved in the communication of their own clinical condition to their partners by young women born with HIV. This is qualitative research, developed in a Specialized HIV Care Service in the southern region of Brazil with ten young people who were born with HIV, using the individual interview, from June 2017 to March 2018. An anchored psychosocial analysis was used within the Framework of Vulnerability and Human Rights. Two groups emerged: the first composed of young women who chose to communicate with their partners at the beginning of affective relationships; and the second, with the young women who postponed such communication. All of them experienced apprehensions and fears regarding the partner's reaction, thought about or adopted some strategies for communication, and reported situations of lesser involvement in HIV prevention behaviors by couples/partners. Care practices that dialogue with young women about the unique difficulties in their intersubjective contexts, crossed by structural social issues, are essential in order to support them in communicating their HIV status to their partners in as soon as possible, in adopting preventive strategies, and in accessing resources that protect their and their partners' sexual and reproductive health.

HIV serodiscordant sexual partners: social representations of health care professionals / Parejas sexuales serodiferentes cuanto al VIH: representaciones sociales de los profesionales de servicios de salud / Parceiros sexuais sorodiferentes quanto ao HIV: representações sociais dos profissionais de serviços de saúde

ABSTRACT Objectives: to understand the structure of the social representations of health professionals from HIV/AIDS Specialized Care Services about HIV-positive partners. Methods: this is a qualitative study, based on the structural aspect of Social Representations, developed in specialized services of the metropolitan area of a state in the Northeast Region. Fifty-one professionals were interviewed using the technique of free association of words, processed by the software IRaMuTeQ, by means of prototypical and similarity analysis. Results: the central nucleus was constituted by the terms "partnership", "love" and "fear", showing appreciation of meanings inherent to their beliefs, values and experiences that bring possibilities of reflections for health practices. Final Considerations: the findings reinforce the impacts generated in the different segments of the lives of people living with HIV and in their emotional bonds. This highlights the need for the implementation of care strategies contemplating the biopsychosocial care model rather than the biological model.

RESUMEN Objetivos: aprender estructura de representaciones sociales de personal de salud de Servicios de Asistencia Especializada VIH/SIDA sobre parejas que viven en serodiferencia cuanto al VIH. Métodos: estudio cualitativo, fundamentado en la vertiente estructural de Representaciones Sociales, desarrollado en servicios especializados de la región metropolitana de un estado del Nordeste. Entrevistados 51 profesionales con aplicación de técnica de asociación libre de palabras, procesadas por software IRaMuTeQ, mediante análisis prototípico y de similitud. Resultados: el núcleo central constituido por los términos "compañerismo", "amor" y "miedo", evidenciando valorización de sentidos inherentes a sus creencias, valores y experiencias que traen posibilidades de reflexiones para las prácticas de salud. Consideraciones Finales: hallados refuerzan los impactos generados en los diferentes segmentos de la vida de las personas que viven con VIH y en sus vínculos afectivos. Eso señala la necesidad de implementación de estrategias asistenciales contemplando el modelo de cuidado biopsicosocial en detrimento del modelo biológico.

Isso ressalta a necessidade da implementação de estratégias assistenciais contemplando o modelo de cuidado biopsicossocial em detrimento do modelo biológico.

Factores asociados a Chlamydia trachomatis en mujeres con vaginitis atendidas en atención primaria en salud / Factors associated with Chlamydia trachomatis in women with vaginitis attending in primary health care

INTRODUCCIÓN: Chlamydia trachomatis es reconocida como el agente causal de una de las infecciones de transmisión sexual (ITS) más común y curable. En mujeres, puede ser gatillante de enfermedad inflamatoria pélvica, un factor de riesgo para infertilidad o adquisición de otras ITS. OBJETIVO: Determinar C. trachomatis en mujeres con diagnóstico clínico de vaginitis asociando factores sociodemográficos, sexuales, clínicos y microbiota vaginal. PACIENTES Y MÉTODOS: Participaron 121 mujeres voluntarias > 18 años, con diagnóstico clínico de vaginitis y descarga vaginal anormal, atendidas en servicios de atención primaria en salud (APS) en Temuco-Chile. Se tomó muestra de flujo vaginal, determinándose C. trachomatis por una reacción de polimerasa en cadena convencional y microbiota vaginal por tinción de Gram. Se colectaron datos clínicos, sociodemográficos y sexuales mediante encuesta. RESULTADOS: Rango de edad 18-61 años. La frecuencia de C. trachomatis fue 14,9%. Se asoció C. trachomatis a mayor número de parejas sexuales en los últimos 5 años (p = 0,001), relaciones sexuales oral más anal (p = 0,055) y juguetes sexuales (p = 0,027). Asociación no significativa hubo con vaginosis bacteriana 31,2% (p = 0,091) e inicio de la actividad sexual < 18 años 20,6% (p = 0,07). CONCLUSIONES: Sería beneficioso incorporar en la semiología ginecológica de las mujeres atendidas en servicios de APS, los factores encontrados como favorecedores de infección por C. trachomatis, pues ello podría ayudar al manejo de esta ITS.

BACKGROUND: Chlamydia trachomatis is recognized as the causative agent of one of the most common and curable sexually transmitted infections (STIs). In women, it can be a trigger for pelvic inflammatory disease, a risk factor for infertility or acquisition of other STIs. AIM: To determine CT in women with vaginitis and associate it with sociodemographic, sexual, clinical, and vaginal microbiota factors. Methods: 121 female volunteers > 18 years of age, with a clinical diagnosis of vaginitis and abnormal vaginal discharge, attending in primary health care services (PHC) in Temuco-Chile were recluted. A vaginal discharge sample was taken, determining C. trachomatis by polymerase chain reaction and vaginal microbiota by Gram stain. Clinical, sociodemographic and sexual data were collected by survey. RESULTS: Age range was 18-61 years. The frequency of C. trachomatis was 14.9%. C. trachomatis was associated with a higher number of sexual partners in the last 5 years (p = 0.001), oral plus anal sex (p = 0.055) and sex toys (p = 0.027); there was a non-significant association with bacterial vaginosis 31.2% (p = 0.091) and initiation of sexual activity < 18 years 20.6% (p = 0.07). CONCLUSIONS: It would be beneficial to incorporate in the gynecological semiology of the women attended in PHC services, the factors found to favor C. trachomatis infection, as this could help the management of this STI.

Estratégias de notificação de parceiros sexuais de pessoas com infecções sexualmente transmissíveis: ensaio clínico randomizado / Estrategias para reportar parejas sexuales de personas con enfermedades de transmisión sexual: ensayo clínico randomizado / Strategies for notifying sexual partners of people with sexually transmitted infections: a randomized clinical trial*

RESUMO Objetivo Comparar a efetividade da comunicação verbal e por cartão no comparecimento de parceiros sexuais de pessoas com infecções sexualmente transmissíveis com fatores associados ao seu êxito. Método Ensaio clínico, controlado, randomizado, cuja intervenção consistiu no oferecimento de um cartão de notificação para os pacientes-índices entregarem aos seus parceiros. Resultados A amostra foi de 189 pacientes-índices, 94 do grupo controle que convidaram verbalmente os parceiros sexuais para atendimento e 95 do grupo intervenção que levaram o cartão de notificação de parceiros como forma de convite para atendimento. Houve comparecimento de 52,6% dos parceiros convidados por cartão, e 43,6% dos convidados verbalmente, mas sem diferença estatística significativa (p=0,215). Os fatores associados ao não êxito no comparecimento de parceiros foram: não residir com o parceiro (p=0,0001), não ter parceiros fixos (p=0,0001), ter parceria casual (p=0,028) e usar preservativo com parceiro fixo (p=0,045). O tipo de infecção não influenciou a vinda do parceiro. Conclusão Face à ausência de maior efetividade na notificação por cartão, recomenda-se outro modelo de cartão contendo informações destinadas a parceiros para ser usado combinado a outros métodos.

ABSTRACT Objective To compare the effectiveness of verbal communication and communication by card in getting sexual partners of people with sexually transmitted infections to attend a health service and the factors associated with the success of these types of communication. Method Clinical, controlled, and randomized study, whose intervention was offering a reporting card for index patients to hand to their sexual partners. Results The sample was 189 index patients, 94 of whom were in the control group, and verbally invited their sexual partners to receive care, and 95 were allocated to the intervention group, and took their partner's reporting card to their partners as a way to invite them to receive care. The percentage of partners invited by card who came to the service was 52.6%, in contrast with 43.6% among partners who were invited verbally, but no significant statistical difference was found (p=0.215). The factors associated with failure to convince partners to come to the service were: not living with the partner (p=0.0001); not having a steady partner (p=0.0001); having casual partners (p=0.028); and using condoms with a steady partner (p=0.045). The infection type did not influence the studied partners' visits to the service. Conclusion Given the failure to achieve effectiveness when applying the reporting by card, the authors recommend another card model containing information for partners to be used in combination with other methods.

Social network characteristics of gay men college students in Tianjin seeking sex partners / 中国学校卫生

Objective@#Based on the MSM college students in Tianjin, this study aims to explore the demographic and behavioral characteristics of MSM with different sexual partners, and to provide evidence and information for intervention in combination with social networks.@*Methods@#According to the source and access of seeking sexual partners, 546 MSM of Tianjin college students aged 18-24 in 2018 Jan. and 2019 Dec. were divided into internet-based MSM (396) and traditional MSM (150). Chi-square test and rank-sum test were used to compare the demographic information, sexual behavior characteristics, HIV prevention and testing awareness, and psychoactive substance use of the two MSMs, and Logistic regression was used to explore factors affecting college students use of the Internet for sexual partners.@*Results@#Internet-based MSM has advantages in receiving HIV testing and safety consulting services, AIDS knowledge level, and peer education in the past year (P<0.05). The psychoactive substance use of the survey population reached more than 40%, and the awareness rates of pre-exposure prophylaxis and post-exposure prophylaxis were 32.98% and 55.32%, respectively. After multivariate Logistic regression analysis, MSM students who had received condom distribution, AIDS counseling and peer education (OR=2.16, 1.98, P<0.01) were more inclined to use the Internet for sexual partners.@*Conclusion@#Relevant departments can use the Internet to intervene in the prevention and control of MSM in colleges and universities in terms of AIDS-related knowledge, HIV testing, and mental substances.

Association between the characteristics of sexual partners and substance use before sexual behavior in young male students who have sex with men / 中国学校卫生

Objective@#To understand the characteristics of sexual partners and the influence of having multiple sexual partners on substance use among young male students man who have sex with men (MSM) in China, and to provide scientific basis for the prevention and control of HIV/AIDS among young MSM students.@*Methods@#A mixed recruitment method of snowball sampling and respondent driven sampling was used to recruit young MSM students in Beijing and Tianjin, and a questionnaire survey was conducted among 220 participants from November to December 2019. Chi-square test and generalized linear model multi-factor Logistic regression were used to analyze the influencing factors of substance use before sexual behavior.@*Results@#The average age of them was (22.39±2.57) years old, 84.5% of them were students, the average age of first sexual behavior was (18.83±2.45) years old, 44.1% of them had two or more sexual partners (including fixed sexual partners, temporary sexual partners and commercial sexual partners), 22.7% had more than one male fixed partner. After adjusting for age and education, having multiple sexual partners was risk factor for drinking alcohol before sex (aOR=2.97) or substance abuse (aOR=2.39). Having male temporary sexual partner was an risk factor in substance use before sexual behavior(OR=4.10).@*Conclusion@#The characteristics of sexual partners among young MSM students are complex, and the proportion of multiple sexual partners is high. Having fixed single sexual partner can reduce the risk of substance use before sexual behavior. AIDS prevention education for young MSM students should be further strengthened.

Syphilis in pregnant women: implications of diagnosis revelation and partner notification strategies / Sífilis em gestantes: implicações da comunicação do diagnóstico e estratégias de convocação do parceiro

Introduction: The low percentage of sexual partners of pregnant women with treated syphilis is one of the main obstacles to the control of congenitalsyphilis. Objective: To analyze the notification of the syphilis diagnosis to the sexual partner of the pregnant woman, its implications and the suggested summoning strategies. Methods: This is a qualitative research conducted in Fortaleza, State of Ceará, from April to October, 2014. A total of 14 women reported with syphilis during prenatal care and nine sexual partners were interviewed. The thematic content analysis and the idea association tree were used to analyze and reveal the results. Results: Pregnant women prefer to communicate the diagnosis to their partner, but they say they need help from the professional for this moment. Among the partners there was no consensus about this strategy, as it generates conflicts for the couple. They therefore indicated other means of communication considered more appropriate. It was found that there is no ideal model of notification of sexual partner of pregnant woman with syphilis. Conclusion: According to the interviewees' reports, we can conclude that the best way is the one that considers the relationship context and the singularities informed by the patients.

Introdução: O baixo percentual de parceiros sexuais de gestantes com sífilis tratados representa um dos principais entraves para o controle da sífilis congênita. Objetivo: Analisar a notificação do diagnóstico de sífilis ao parceiro sexual da gestante, suas implicações e as estratégias de convocação sugeridas. Métodos: Trata-se de uma pesquisa qualitativa realizada em Fortaleza, Ceará, de abril a outubro de 2014. Foram entrevistadas 14 mulheres notificadas com sífilis durante o pré-natal e nove parceiros sexuais. Utilizou-se da análise de conteúdo temática e a árvore de associação de ideias para análise e apresentação dos resultados. Resultados: As gestantes preferem comunicar o diagnóstico ao parceiro, mas referem necessitar de ajuda do profissional para esse momento. Entre os parceiros, não houve consenso acerca dessa estratégia, por gerar conflitos para o casal. Assim, indicaram outros meios de comunicação que consideram mais adequados.

Inicio sexual en contexto de sexo casual y su asociación a comportamientos de riesgo en salud sexual y reproductiva en adolescents / Sexual initiation in the context of casual sex and its association with risk behaviors in sexual and reproductive health in adolescents

RESUMEN Antecedentes: Los adolescentes que se comprometen en actividad sexual en un contexto de sexo casual, pueden desarrollar patrones de actividad sexual que los llevarán a resultados en salud negativos tales como embarazo no planificado, infecciones de transmisión sexual, y mayor exposición a múltiples parejas sexuales. Objetivo: Analizar la asociación entre inicio sexual en contexto de sexo casual y comportamientos de riesgo en la salud sexual y reproductiva en adolescentes. Método: Estudio transversal y analítico en una población adolescente de ambos sexos. Se compararon adolescentes que iniciaron actividad sexual en un contexto de relaciones románticas y aquellos que lo hicieron en un contexto de sexo casual. Se analizó la asociación entre edad inicio relaciones sexuales, número de parejas sexuales, uso de método anticonceptivo y variables personales y familiares seleccionadas. Resultados: Se entrevistaron 3.565 adolescentes que habían iniciado relaciones sexuales. Las variables personales y familiares asociadas al inicio sexual en un contexto de sexo casual fueron: tener escolaridad básica, menor mediana de notas, antecedente de repitencia, proyectos académicos futuro solo terminar enseñanza media o secundaria, malas relaciones familiares, y disfunción familiar. Los comportamientos de riesgo en salud sexual en adolescentes de ambos sexos, que iniciaron actividad sexual en un contexto de relación de sexo casual fueron: inicio sexual más temprano, no uso de métodos anticonceptivos y mayor número de parejas sexuales. Conclusión: El inicio de la actividad sexual en un contexto de sexo casual expone a los adolescentes a mayores riesgos en sus comportamientos en su salud sexual y reproductiva cuando se comparan con aquellos que inician actividad sexual en un contexto más romantico.

ABSTRACT Background: Adolescents who engage in sexual activity in a non-romantic relationship may develop patterns of sexual activity that lead to negative health outcomes such as unplanned pregnancy, sexually transmitted infections, and increased exposure to multiple sexual partners. Objective: To analyze the association between sexual initiation in the context of non-romantic relationship and risk behaviors in sexual and reproductive health in adolescents. Method: Cross-sectional and analytical study in a teenage population of both sexes. We compared adolescents who initiated sexual activity in a context of romantic relationships and those who did it in a non-romantic context. The association between age at sexual initiation, number of sexual partners, use of contraceptive method and selected personal and family variables was analyzed. Results: 3,565 adolescents who had initiated sexual intercourse were interviewed. The personal and family variables associated with sexual initiation in a non-romantic context are: having a basic schooling, a lower grade point average and repeating background, and academic projects finishing secondary or high school, bad family relationships, and family dysfunction. The risk behaviors in sexual health in adolescents of both sexes who initiated sexual activity in a context of non-romantic relationship were: sexual debut earlier, no use of contraceptive methods and greater number of sexual partners. Conclusion: The beginning of sexual activity in a non-romantic context exposes adolescents to risk behaviors in their sexual and reproductive health.

Related factors on sexual partners regarding receipt of HIV test among HIV positive men who have sex with men in Zhejiang province / 中华流行病学杂志

Objective@#To understand the situation and influencing factors related to the promotion of HIV testing program among sex partners in newly diagnosed HIV positive MSM in Zhejiang province during 2015 to 2017.@*Methods@#Newly diagnosed HIV positive MSM in Zhejiang province from 2015 to 2017 were collected and provided four rounds of testing services to their sexual partners so as to study the consequences. Chi-square test was conducted to compare the difference between groups while multivariate logistic regression was conducted to analyze the related influencing factors.@*Results@#A total of 6 269 HIV positive MSM were provided with four rounds of testing services to their sexual partners. 1 925 HIV positive MSM (30.7%, 1 925/6 269) were successfully persuaded in mobilizing their sexual partners to participate in the HIV testing services. However, 4 344 HIV positive MSM (69.3%, 4 344/6 269) refused to do so. A total of 2 126 sexual partners received HIV testing and the HIV positive rates of those sexual partners appeared as 13.0% (277/2 126, 95%CI:11.6%-14.5%) and 78.7% (218/277, 95%CI: 73.8%-83.6%). Results from the multivariate logistic regression analysis indicated that factors as: HIV positive MSM that participated in the study in 2016 (compared with participated in the study in 2015, OR=1.581, 95%CI: 1.370-1.823), in 2017 (compared with participated in the study in 2015, OR=1.394, 95%CI: 1.208-1.608), living in the reporting city (compared with lived outside the reporting city, OR=1.518, 95%CI: 1.320-1.745), being married (compared with unmarried/divorced/widowed, OR=4.449, 95%CI: 3.837-5.160), having education level of junior high school or below (compared with education level of senior high school or above, OR=1.203, 95%CI: 1.058-1.367), numbers of homosexual partners >5, (compared with numbers of homosexual partner from past between 1-5, OR=1.236, 95%CI: 1.095-1.395), active detection (compared with passive detection, OR=1.340, 95%CI: 1.193-1.506) were more likely to relate to the successful persuasion on their sexual partners to receive the HIV testing. There was no statistical difference noticed between HIV-infected homosexual partners and their corresponding HIV positive MSM, in terms of socio-demographic situations.@*Conclusions@#HIV positive MSM should promote their sexual partners to receive HIV testing. This seemed an important role in expanding the HIV testing in this population. However, the program needs to be further improved and included in daily work, focusing on those partners with similar social and demographic characteristics with those infected MSM.

Association between sexual sensation seeking and sexual risk behaviors among men who have sex with men in Guangzhou / 中华疾病控制杂志

Objective To evaluate the association between sexual sensation seeking (SSS) and sexual risk behaviors among men who have sex with men (MSM) in Guangzhou. Methods MSM aged 18 and over were recruited in Zhitong Charity from June 2017 to April 2018. Data on socio-demographic characteristics, sexual behaviors and SSS were collected using an electronic questionnaire. Logistic regression analyses were performed to evaluate the association between SSS and sexual risk behaviors. Results A total of 500 MSM were included in the current study. The mean age of the participants was (27.77±5.96) years old. The multiple logistic regression analyses showed that MSM with high SSS scores were more likely to engage in multiple sexual partners (OR=2.05, 95% CI: 1.40-2.30,P<0.001), one-night stand (OR=2.11, 95% CI: 1.44-3.09,P<0.001), and unprotected anal intercourse (OR=1.70, 95% CI: 1.16-2.50,P=0.007) than those with low SSS scores. Conclusions High SSS is associated with an increased risk of sexual risk behavior among MSM in Guangzhou. The behavior intervention strategy should be tailored for MSM with high SSS to improve the effectiveness to reduce sexual risk behaviors.

Concurrence and selection of sexual partners as predictors of condom use among Mexican indigenous migrant workers / Concurrencia y selección de parejas sexuales como predictores del uso de condón en trabajadores migrantes indígenas mexicanos

ABSTRACT Objective To identify if the selection of mixed sexual partners and the existence of concurrent partners are predictors of condom use in indigenous migrant agricultural workers from Colima, Mexico. Methods Analytical cross-sectional study using an egocentric sexual network approach. Community interviewers applied a structured questionnaire to 192 indigenous migrant workers in a sugarcane agro-industrial context. Data were analyzed with binary logistic regression; odds ratios (OR) and 95% confidence intervals (CI 95%) were estimated. Results In the logistic regression model, adjusted odds (OR; 95% CI) of steady condom use were lower within partnerships of the same indigenous ethnicity compared to other partnerships (0.30; 0.17-0.53), partnerships that were concurrent to other partnerships (0.27; 0.15-0.50), and partnerships that used illegal drugs during sex to other partnerships (0.23; 0.11-0.49). Those variables were actually associated with increased risk of unprotected sex (occasionally or never using condoms), and therefore exposures were unprotected. Conclusion Sexual partners of the same ethnicity, concurrent partnerships and partnerships that use illegal drugs favor the low frequency of constant condom use and, in turn, the vulnerability to STIs and HIV transmission in indigenous migrant agricultural workers.(AU)

RESUMEN Objetivo Identificar si la selección de parejas sexuales mixtas y la existencia de parejas concurrentes son predictores del uso de condón en trabajadores agrícolas migrantes indígenas de Colima, México. Métodos Estudio transversal analítico bajo un enfoque egocéntrico de redes de parejas sexuales. Entrevistadores comunitarios aplicaron un cuestionario estructurado a 192 trabajadores migrantes indígenas de un contexto agroindustrial cañero. Los datos se analizaron mediante regresión logística binaria; se calcularon razones de momios (RM) e intervalos de confianza (IC) de 95%. Resultados En el modelo de regresión de predictores del uso constante de condón, las RM ajustadas (RM; IC 95%) fueron: menores en las parejas sexuales de la misma etnicidad que en las otras parejas (0.30; 0.17-0.53), menores en las parejas concurrentes que en las no concurrentes (0.27; 0.15-0.50); y menores en las parejas usuarias de drogas ilegales que en las no usuarias (0.23; 0.11-0.49). El sentido predictor de estas variables se asoció a un mayor riesgo de sexo no protegido (algunas veces o nunca usaron condón). Conclusión Las parejas sexuales de la misma etnicidad, las parejas concurrentes y las parejas que usan drogas ilegales favorecen una baja frecuencia de uso constante del condón y con ello la vulnerabilidad a la transmisión de ITS y VIH en los trabajadores agrícolas migrantes indígenas.(AU)

O ser-com-o-outro na condição sorodiscordante: uma abordagem fenomenológica da vulnerabilidade individual ao HIV / The being-with-another in the serodiscordant condition: a phenomenological approach to the individual HIV vulnerability

Compreender a sorodiscordância e a vulnerabilidade individual ao HIV nas relações de ser-com-o-outro sorodiscordante. Estudo qualitativo, ancorado na Fenomenologia Hermenêutica de Martin Heidegger. Participaram do estudo oito pacientes soropositivos e suas parcerias sorodiscordantes, totalizando 16 participantes. A entrevista foi o instrumento utilizado para obtenção das narrativas vividas pelos casais. Os conceitos fenomenológicos de "ser-com" e "ser-no-mundo", descritos por Heidegger, permitiu que os sentidos e significados relacionados ao fenômeno da sorodiscordância fossem evidenciados de forma detalhada. As construções sociais de masculinidade, a reduzida capacidade do casal em negociar prática de sexo seguro, o uso da terapia antiretroviral como fator de proteção ao HIV acrescidos das influências culturais foram evidenciados como as principais situações de vulnerabilidade individual da existência sorodiscordante. A compreensão do significado existencial de ser-casal-sorodiscordante, segundo a estrutura ontológica "ser-um-com-o-outro" instiga mudanças da práxis do enfermeiro, oportunizando um atendimento diferenciado e integral ao casal sorodiscordante.

To comprehend the serodiscordance and individual HIV vulnerability in being-with-another serodiscordant relationships. A qualitative study anchored in the Hermeneutic Phenomenology of Martin Heidegger. Eight seropositive patients and their serodiscordant partners participated in the study, totalizing 16 participants. The interview was the instrument used to obtain narratives experienced by the couples. The phenomenological concepts of "being-with" and "being-in-the-world", described by Heidegger allowed the senses and meanings related to the serodiscordance phenomenon to be evident in detail. The social constructions of masculinity, the reduced ability of the couple in negotiating safe sex practice, the use of antiretroviral therapy as an HIV protection factor added to cultural influences were found as the main situations of the individual vulnerability of the serodiscordant existence. The comprehension of the existential meaning of being-couple-serodiscordant, according to the ontologic structure "being-one-with-another" instigate changes in the nurse praxis, giving the opportunity to distinctive and integral attention to the serodiscordant couple.

Religiosidad juvenil y su asociación a comportamientos sexuales en adolescentes consultantes en un centro de salud sexual y reproductiva en la Región Metropolitana / Youth religiosity and its association to sexual behaviors in adolescent consultants in a sexual and reproductive health center in the Metropolitan Region

ANTECEDENTES: La evidencia muestra que uno de los factores fuertemente asociado con la postergación de la actividad sexual, es la afiliación o membrecía a religiones judeo-cristianas, con códigos estrictos de conductas. OBJETIVO: analizar la asociación entre religiosidad y comportamientos sexuales en adolescentes. MÉTODO: Estudio transversal analítico en una población adolescente. Se compararon adolescentes católicas, evangélicas y sin religión. Se analizó la asociación entre afiliación y asistencia a servicios religiosos y edad de inicio de la actividad sexual, uso de condón y número de parejas sexuales. RESULTADOS: Se entrevistaron 5.231 adolescentes (mediana de edad 16 años, 91,6% mujeres, 97,3% estudiantes). Las adolescentes que se declaran evangélicas, dejan de asistir a los servicios religiosos en mayor proporción que las adolescentes católicas al iniciar actividad sexual. La afiliación religiosa, sea católica o evangélica, retarda el inicio de la actividad sexual y disminuye el riesgo de tener más de una pareja sexual, comparadas con aquellas sin religión. Pero la afiliación religiosa, sea católica o evangélica, aumenta la posibilidad del no uso de condón, en comparación con aquellas sin religión. CONCLUSIÓN: La afiliación religiosa influye en los comportamientos sexuales en adolescentes, disminuyendo el riesgo en el inicio sexual y en el número de parejas sexuales, aumenta la posibilidad del no uso de condón pero no influye en el uso de anticonceptivos orales.

BACKGROUND: Evidence shows that one of the factors associated with the postponement of sexual activity is membership or affiliation to Judeo-Christian religions, with strict codes of behavior. OBJECTIVE: To analyze the association between religiosity and sexual behaviors in adolescents. METHOD: Analytical cross-sectional study conducted in a population of adolescents. Were compared catholic, evangelical and without religion. Association between affiliation and assistance religious services and age sexual initiation, condom use and number of sexual partners were analyzed. RESULTS: In total, 5.231 adolescents (median age 16 years, 91.6% female, 97.3% students,), were interviewed. Adolescents who declare to be evangelicals cease to attend religious services in greater proportion than Catholic adolescents when initiating sexual activity. Religious affiliation, whether Catholic or evangelical, delay the onset of sexual activity and decreases the risk of having more than one sexual partner, compared with those without religion, but religious affiliation, whether Catholic or evangelical, increases the risk of non-use of condoms, compared to those without religion. CONCLUSION: Religious affiliation influences sexual behaviors in adolescents, decreasing the risk in the age of sexual debut and in the number of sexual partners but increasing the risk in the non-use of the condom but does not influence the pill use.

Factors associated with syphilis/HIV infection among men who have sex with men in Shenzhen,2011-2016 / 中华预防医学杂志

Objective@#To investigate the factors associated with syphilis/HIV infection among men who have sex with men (MSM) maintaining a single sexual partner in Shenzhen.@*Methods@#Respondent driven sampling and snowball sampling method were used to recruit MSM receiving voluntary counseling and testing in Shenzhen Rainbow clinic from 2011 to 2016. Inclusion criteria: aged 18 years and above; reported having one or more anal sexual partners in the recent 6 months. A total of 3 109 men who have sex with men (MSM) were involved in the study. Questionnaire-based interviews were conducted on a one-on-one basis. Data were collected including socio-demographic information, human immunodeficiency virus (HIV) testing history, history of blood donation and drug abuse in the recent two years, self-identified sexual orientation, role in homosexual behavior, ever being money boys (MB) and clients of MB, female sexual partners in the recent 6 months. 5 ml blood samples were taken after questionnaires. Syphilis was screened using toluidine red unheated serum test for the antibody of treponema pallidum and then confirmed by treponema pallidum particle assay. The enzyme-linked immunosorbent assay (ELISA) was used for screening HIV and western blot was used to confirm the HIV screening results. The difference of condom use among MSM between female sexual partners and male sexual partners were compared. Multivariate unconditional stepwise logistic regression model was used to analyze factors associated with syphilis infection and HIV positive among MSM.@*Results@#A total of 3 109 eligible participants with mean (SD) age of 31.49 (8.64) years were enrolled in this study. Among them, 565 cases were infected with syphilis (18.17%), 330 cases were infected with HIV (10.61%), and 165 cases (5.31%) were syphilis co-infected with HIV. 791 (25.44%) reported maintaining a single sexual partners in the recent 6 months. Compared to MSM with multiple sexual partners, the prevalence of syphilis and HIV infection among MSM with a single sexual partner were lower, and the OR (95%CI) were 0.64 (0.51-0.81) and 0.66 (0.49-0.90), respectively.@*Conclusion@#The proportion of fixed single sexual partner was much lower among MSM in Shenzhen. Maintaining a single sexual partners can reduce the risk of syphilis/HIV infection among MSM.
