Item Adolescentes encuentran fácil tomar sus propias muestras para estudio de infecciones de transmisión sexual(Sociedad Chilena de Infectología, 2017) Huneeus, Andrea; Fernández, Mario; Schilling, Andrea; Parra, Paulina; Zakharova, AleksandraBackground: As alternative for patients that fear genital examination, we assessed adolescent's comfort and ease with self-collected samples for nucleic acid amplification testing for sexually transmitted infections. Patients and Methods: Sexually active Chilean adolescents and youth under 25 years (174 males and 117 females) were enrolled. Females used self-collected vaginal swabs and males collected first-stream urine. A satisfaction survey evaluating self-sampling system was applied. Results: Self-collection was considered easy in 99.3% of the interviewees (CI 95% 0.88-0.98). In women, 79.3% preferred vaginal self-collected samples than pelvic exam (CI 95% 0.73-0.85). In men, 80.3% preferred self-collected first-stream urine to urethral swabs (CI 95% 0.73-0.87). Assuming that self-collected sampling were available, 89.6% of women (CI 95% 0.85-0.94) and 93.2% of men (CI 95% 0.89-0.98) would be prone to be tested more often. Ease of self-collected sampling is not associated with age, gender, educational level or poverty. Conclusions: Chile currently does not have sexually transmitted infections surveillance or screening programs for youth and adolescents. Given self-collected sampling's good acceptability, it could be successfully used when these programs are implemented.Item Induced Abortion According to Socioeconomic Status in Chile(2020-08) Huneeus, Andrea; Capella, Daniela; Cabieses, Báltica; Cavada, GabrielStudy Objective: The Chilean legislation forbids induced abortion, so little is known of the young women who have abortions and what determinants are associated with this practice. In this study we examined the association between adolescents and young women who have had induced abortions and socioeconomic status and compared them with counterparts who reported not having a history of abortion. Design, Setting, Participants, and Main Outcome Measures: Drawing on the 2015 Chilean National Youth Survey, a population-based sample of general community youth aged 15-29 years, we conducted a study on 2439 sexually active females. Bivariate and multiple logistic regression was used to examine the relationship between participants who had induced abortions and participants that had not according to socioeconomic status (low, middle, high), while controlling for demographic, sexual behavior, and cultural covariates. Results: 5.15% (n = 129) of participants declared having induced an abortion in the past. Participants with high socioeconomic status had 4.89 (95% confidence interval, 1.44-16.51) higher odds of induced abortion compared with participants with low socioeconomic status. Those with middle socioeconomic status had 1.8 (95% confidence interval, 1.02-3.24) higher odds of induced abortion compared with those with low socioeconomic status. Urban or rural residence, indigenous identification, age of sexual debut, contraceptive use at the time of sexual debut, adolescent pregnancy, and religious and political identification did not correlate with induced abortion rates. Conclusion: In Chile, where induced abortion is legally restricted, a social gradient was found in the chance of having had an induced abortion according to socioeconomic status; adolescent and young women with higher socioeconomic advantage reported more induced abortions compared with those with low socioeconomic status.Item Prevalence of Chlamydia Trachomatis, Neisseria Gonorrhoeae, and Trichomonas Vaginalis Infection in Chilean Adolescents and Young Adults(2018) Huneeus, Andrea; Schilling, Andrea; Fernandez, Mario I.Study objective: To determine the prevalence of Chlamydia trachomatis, Neisseria gonorrhoeae, and Trichomonas vaginalis infection in sexually active Chilean adolescents and young adults. A comparative analysis was performed between genders to identify demographic, clinical, and sexual behavior characteristics to predict the occurrence of C trachomatis. Design: Analytical observational study. Setting: Santiago, Chile. Participants: Two hundred eighty-six sexually active volunteers aged 24 years or younger (171 female and 115 male); 82.9% (237/286) of them were classified as having high socioeconomic status. Interventions: Confidential survey and self-collected samples (urine for men and vaginal swabs for women). Main outcome measures: Prevalence, demographic characteristics, symptoms, and sexual behavior characteristics. Results: The prevalence rate of C trachomatis was 8.7% (10/115) in men and 8.8% (15/171) in women (P = .58). N gonorrhoeae was detected in 1 subject, whereas no T vaginalis cases were detected. In multivariate analysis, having some college education was protective (odds ratio [OR], 0.28; 95% confidence interval [CI], 0.09-0.89), whereas having a higher number of sexual partners was a risk factor (OR, 1.19; 95% CI, 1.1-1.3) for C trachomatis infection. The latter was also predicted by postcoital bleeding (OR, 4.6; 95% CI, 1.30-16.23) in the female model. Conclusion: C trachomatis infection rates were similar between both genders. Protective characteristics for the occurrence of this infection were having some college education, lower number of sexual partners, and if female, the absence of postcoital bleeding. This study highlights the importance of C trachomatis screening among the Chilean affluent population younger than 25 years. However, further studies are needed in a more diverse and representative sample to recommend universal screening in Chilean adolescents and young adults.Item Prevalencia y manejo de condilomas en población consultante en Chile: estudio “DIACON”(2019) Schilling, Andrea; Huneeus, Andrea; Masso, Alejandra; Rivera, Francisca; Cavada, GabrielIntroducción: Los condilomas o verrugas genitales (VG) son la infección de transmisión sexual (ITS) más diagnosticada en los centros de ITS en Chile, pero no existen estadísticas poblacionales. Objetivos: Describir la prevalencia de VG en pacientes de 18-60 años que acuden a consulta ambulatoria de dermatología, ginecología y urología; características demográficas de los pacientes y prácticas de diagnóstico y tratamiento. Material y Métodos: A una muestra de especialistas chilenos estratificados por región, población y sexo de pacientes se les proporcionó un diario de registro y aplicó un cuestionario. Resultados: Prevalencia VG grupo total: 2,4%; en grupo etario 18-34 años: 3,7%; en grupo etario 35-60 años: 1,29% (p = 0,0000). La edad media de los pacientes con VG fue 29,4 años en mujeres y 32,7 años en hombres (p = 0,019); la distribución por edad fue diferente según sexo y sistema de salud. La inspección visual fue el método diagnóstico más frecuente y la crema de imiquimod el tratamiento más común. Hubo diferencias en el uso de herramientas diagnósticas y terapéuticas según sexo del paciente, especialidad del médico y sistema de salud. Conclusiones: Existe una alta prevalencia de VG, que debería ser tomada en cuenta para planificar las intervenciones de salud pública para abordar este problema.Item Síndrome de Hemivagina Obstruida, Útero Didelfo y Agenesia Renal Ipsilateral (OVHIRA), Drenado Parcialmente por Fístula Útero-Uterina Espontánea(2017) Huneeus, Andrea; Sanz Acuña, Antonia; Pino Poblete, Víctor Manuel; Cunill, EduardoAntecedentes: El síndrome de hemivagina obstruida, útero didlefo y anomalía renal ipsilateral (OVHIRA) es una malformación mülleriana infrecuente. Objetivo: Se presenta un caso con una complicación no antes descrita y se hace una revisión de la literatura hasta la fecha. Caso clínico: Mujer de 12 años de edad con antecedentes de diagnóstico de útero bicorne y agenesia renal derecha en la infancia. Veintidós meses post menarquia consulta por algia pelviana y dismenorrea premenstrual. Ecografía revela hematómetra en cuerpo uterino izquierdo, de 142 x 69 x 61 mm. Resonancia nuclear magnética (RNM) describe además un hematocolpos de 7 x 10 cm y un tabique vaginal transverso de hemivagina izquierda. Se diagnostica OHVIRA y se planifica cirugía para resecar el tabique. Días antes del la cirugía, la paciente tiene episodio de metrorragia. Ecográficamente se constata una disminución considerable del volumen de hematómetra. En la cirugía se pesquisa fístula uterina que comunica útero obstruido izquierdo con útero no obstruido derecho por donde había drenado espontáneamente la hematómetra. Al resecar el tabique vaginal izquierdo se termina de drenar hematómetra y hematocolpos. Al alta, paciente se maneja con dilatación vaginal progresiva por seis meses para evitar la estenosis del tabique. Conclusión: Se presenta una complicación no descrita, fístula útero uterina, de una malformación mülleriana infrecuente (OVHIRA). El proceso diagnóstico meticuloso, la cirugía bien planificada y la dilatación vaginal prolongada permitieron tener éxito en su manejo.Item Type of primary education is associated with condom use at sexual debut among chilean adolescents(American Sexually Transmitted Diseases Asociation, 2014) Huneeus, Andrea; Deardorff, Julianna; Lahiff, Maureen; Guendelman, SylviaBACKGROUND: Although condom use in adolescence is related to higher lifetime educational attainment, the association between primary education (from kindergarten to eighth grade) and adolescent sexual behavior is not well understood. This study examined the association between type of school in which primary education was completed-public, charter, or private-and condom use at sexual debut among Chilean adolescents. METHODS: Drawing on the 2009 Chilean National Youth Survey, a population-based sample of general community youth aged 15 to 29 years, we conducted a study of the 4217 participants who reported onset of sexual activity during adolescence. Bivariate and multple logistic regression was used to examine the relationship between type of primary school attended (60.1% public, 30.3% charter, and 9.6% private) and condom use at sexual debut while controlling for sociodemographic characteristics and sexual behavior. RESULTS: Compared with students who completed their primary education in private or charter schools, students who completed their primary education in public schools had 1.85 (95% confidence interval, 1.12-3.04) and 1.67 (95% confidence interval, 1.26-2.23) higher odds, respectively, of not using condoms at sexual debut. Odds were similar for students living in urban settings, whereas there were too few students attending private schools in rural areas to allow meaningful estimates. CONCLUSIONS: Independent of household income, primary schooling is associated with sexual health behaviors among Chilean adolescents living in urban areas and can serve as a target for public health interventions designed to prevent sexually transmitted infections in adolescence.
