Salud sexual y salud reproductiva en mujeres jóvenes con consumo de sustancias en Chile según datos VIII encuesta nacional de la juventud / Sexual health and reproductive health in young women with substance consumption in Chile according to data VIII national youth survey

OBJETIVOS: Determinar la asociación entre el consumo de sustancias y características de salud sexual y reproductiva de mujeres jóvenes en Chile. MÉTODOS: Estudio transversal analítico en mujeres entre 15 a 24 años. Se formaron 3 grupos: Sin consumo de sustancias (SCS), Consumo no problemático de sustancias (CNPS) y Consumo problemático de sustancias (CPS). Se realizó análisis descriptivo y de asociación entre las variables. Se ajustaron modelos de regresión logística múltiple y ordinal múltiple. RESULTADOS: Muestra de 2.589 jóvenes, el 37,8% correspondió al grupo SCS, 46,3% al grupo CSNP y 15,9% al grupo CPS. En promedio la edad de inicio de actividad sexual fue menor en el grupo CPS (15,9 años p = 0,001) mostrando mayor porcentajes de sexo oral, anal, no uno de condón, relaciones sexuales con parejas menos estables, mayor número de parejas sexuales y violencia en la pareja, (p =0,001). En este grupo se incrementa 5,84 el riesgo de tener la última relación sexual con pareja menos estable (IC95%: 3,90 - 12,01) y 8,35 veces el riesgo de tener 2 o más parejas sexuales (últimos 12 meses) (IC95%: 5,35 - 16,34). En el grupo CNPS se incrementa 1,11 veces el riesgo de tener la última relación sexual con pareja menos estable (IC95%: 1,43 - 3,12), 1,01 veces tener 2 y más parejas sexuales (últimos 12 meses) (IC95%: 1,20 - 3,36). CONCLUSIONES: Reconociéndose que la sexualidad es multifactorial, las mujeres con consumo de sustancias viven situaciones que facilitan riesgos para su salud sexual. El consumo en mujeres jóvenes es un problema de salud pública que presenta desafíos para su abordaje.

OBJECTIVES: To determine the association between substance use and characteristics of sexual and reproductive health of young women in Chile. METHODS: Analytical cross-sectional study in women between 15 and 24 years. Three groups were formed: No substance use (SCS), Non-problematic substance use (CNPS) and Problem substance use (CPS). Descriptive and association analysis was performed between the variables. Multiple logistic regression and multiple ordinal models were adjusted. RESULTS: Sample of 2,589 young people, 37.8% corresponded to the SCS group, 46.3% to the CSNP group and 15.9% to the CPS group. On average the age of onset of sexual activity was lower in the CPS group (15.9 years p = 0.001) showing higher percentages of oral, anal sex, not a condom, sex with less stable partners, greater number of sexual partners and violence in the couple, (p = 0.001). In this group the risk of having the last sexual relationship with a less stable partner is increased 5.84 (95% CI: 3.90 - 12.01) and 8.35 times the risk of having 2 or more sexual partners (last 12 months) (95% CI: 5.35-16.34). In the CNPS group the risk of having the last sexual relationship with a less stable partner is increased 1.11 times (95% CI: 1.43 - 3.12), 1.01 times having 2 and more sexual partners (last 12 months) (95% CI: 1.20-3.36). CONCLUSIONS: Recognizing that sexuality is multifactorial, women with substance use experience situations that facilitate risks to their sexual health. Consumption in young women is a public health problem that presents challenges for its approach.

Edad de inicio sexual y asociación a variables de salud sexual y violencia en la relación de pareja en adolescentes chilenos / Age of sexual initiation and association with variables of sexual health and violence in the couple relationship in Chilean adolescents

RESUMEN Objetivo Analizar la edad de inicio sexual y su asociación a variables de salud sexual y violencia en la relación de pareja (VRP) en adolescentes chilenos. Métodos Estudio transversal y analítico. La muestra se obtuvo de base de datos con representación nacional. Se realizó análisis de regresión logística múltiple controlando por edad y grupo socioeconómico y estratificando por sexo para determinar asociación entre las variables. Resultados En mujeres, el inicio sexual temprano (antes de los 15 años) aumenta en 0,85 veces el riesgo de embarazo no planificado (OR: 1,85; IC95%: 1,08 - 3,15). En hombres el inicio sexual temprano aumenta en 2.33 veces el riego de no usar anticonceptivo en la primera relación sexual (OR: 3,33; IC95%: 1,85 - 6,01) y 4.33 veces de tener 2 y más parejas sexuales durante los últimos 12 meses (OR: 5,33; IC95%: 3,25 - 8,75). La prevalencia de VRP fue 10%, siendo la violencia psicológica la más frecuente en hombres y en mujeres. En las mujeres, la edad de inicio sexual temprano aumenta 5,72 veces el riesgo de violencia física (OR: 6,72; IC95%: 2,52 - 17,87) y 7,82 veces violencia psicológica (OR: 8,82; IC95%: 4,10 - 19,0). Las adolescentes que presentan un inicio temprano de actividad sexual, muestran más frecuencia de prácticas de control y abuso hacia su pareja, en comparación con los hombres. Conclusiones El inicio sexual temprano y la VRP existen con una frecuencia preocupante, existiendo asociación entre ambas, en especial en mujeres, lo que aumenta el riesgo para la salud en general. Es necesaria la capacitación de los equipos de salud y educación e implementación de estrategias integrales que contribuyan a promover la salud y bienestar de los adolescentes.

ABSTRACT Objective To analyze the age of sexual debut, its association with variables of sexual health and intimate partner violence (PV) in Chilean adolescents. Methods Cross-sectional and analytical study. The sample was obtained from a database with national representation. Multiple logistic regression analysis was carried out controlling by age and socioeconomic group and stratifying by sex to determine association between the variables. Results In women, the age of early sexual initiation increases in 0.85 times the risk of unplanned pregnancy (OR: 1.85, 95% CI: 1.08 - 3.15). In men, the age of early sexual debut increases by 2.33 times the risk of not using contraception in the first sexual relationship (OR: 3.33, 95% CI: 1.85 - 6.01) and 4.33 times of having 2 and more sexual partners during the last 12 months (OR: 5.33, 95% CI: 3.25 - 8.75). The prevalence of PV was 10%, psychological violence was the most frequent in men and women. In women, the age of early sexual initiation increases 5.72 times the risk of physical violence (OR: 6.72, 95% CI: 2.52 17.87) and 7.82 times psychological violence (OR: 8.82; 95% CI: 4.10 - 19.0) Adolescents who have an early onset of sexual activity show more evidence of control practices and abuse toward their partner, compared to men. Conclusions Intimate partner violence exists with a worrisome frequency, having an association with early sexual initiation, especially in women, increasing the risk to health in general. It is necessary to train health and education teams and implement comprehensive strategies that contribute to promoting the health and well-being of adolescents.

Diferencias de género en la calidad de vida relacionada con la salud en adolescentes escolarizados chilenos / Gender differences in health-related quality of life of Chilean adolescent students

Background: Health-related quality of life (HRQOL) refers to individuals' perception of their subjective well-being, considering various aspects of their life and the impact on their health. Aim: To analyze gender differences in the HRQOL of adolescent students in Chile, by age, type of school attended, and area of residence. Material and Methods: Analytical cross-sectional study conducted in a population of 5th and 12th grade students attending municipal, subsidized and private schools in 11 regions of the country. HRQOL was assessed with the KIDSCREEN-52, an instrument that has been previously adapted and validated in Chile. The database obtained from that adaption and validation process was analyzed. Results: In total, 7,910 students (median age 14 years, 53% female) completed the questionnaire. Compared to males, females had lower HRQOL scores in most of the KIDSCREEN-52 dimensions. However, males were more likely to have lower scores in the “Peers and Social Support” and “School Environment” dimensions. These differences remained valid when the sample was stratified by age, type of school, and area of residence were analyzed. Conclusions: This study supports the existence of inequalities in the self-perceived HRQOL of Chilean adolescent students. The existing differences are not only related to gender but are also evident when stratifying by type of school attended.

Antecedente de agresión sexual y su asociación con conductas de riesgo en adolescentes consultantes en un centro de atención en salud sexual y reproductiva / History of sexual aggression and its association with risk behavior in adolescents consulting a focus on sexual and reproductive health

Antecedentes: La mayoría de los programas de salud reproductiva en Chile operan bajo la premisa de que todas las mujeres y en especial las adolescentes están o han estado comprometidas en relaciones sexuales consensuales, y no consideran que muchas de ellas pueden ser sobrevivientes de agresión sexual y pueden presentar necesidades diferentes en salud sexual y reproductiva. Objetivo: Examinar cuáles conductas de riesgo y variables sociodemográficas y familiares están asociadas al antecedente de agresión sexual en adolescentes consultantes en un centro de atención en salud sexual y reproductiva. Método: Estudio analítico de corte transversal. La información fue recolectada en la primera consulta a 3.064 adolescentes mujeres entre 12 y 19 años, atendidas en un centro de salud sexual y reproductiva en el período 2003-2010. Se usó regresión logística para identificar los factores asociados a la agresión sexual. Resultados: Un 22,7 por ciento reportó antecedente de agresión sexual. Las conductas de riesgo asociadas al antecedente de agresión sexual fueron: inicio de la actividad sexual bajo coerción o bajo efectos del alcohol, mayor número de relaciones afectivas y parejas sexuales, menor edad al inicio de la actividad sexual, menor promedio de notas, mayor consumo de cigarrillo, de alcohol y drogas, y menor edad al inicio del consumo de drogas. Conclusión: El antecedente de agresión sexual deja a las mujeres expuestas a riesgos en la salud sexual y reproductiva, por lo que los equipos de salud debieran ser capaces de detectar estas problemáticas para poder intervenir en forma adecuada y eficaz.

Background: Most of reproductive health programs in Chile operate under the premise that women and adolescent girls in particular, are or have been engaged in consensual sex and do not consider that many of them may be survivors of sexual abuse, and may have different needs in sexual and reproductive health. Objective: Determine which risk behaviors and familial variables are associated with sexual aggression history in adolescents consulting at sexual and reproductive health center. Method: Cross-sectional analytical study. The information was gathered from a structured interview applied in the first consultation to 3,064 adolescent girls between 12 and 19 years, who attended a sexual and reproductive health centre for the period 2003-2010. Logistic regression was used to identify factors associated with sexual assault. Results: A 22.7 percent reported sexual assault history. Risk behaviors associated with sexual aggression were: onset of sexual activity forced or under influence of alcohol, as many relationships and sexual partners, younger age at onset of sexual activity, lower grade point average, cigarette smoking, alcohol and drug use and younger age at onset of drug use. Conclusion: A history of sexual aggression leaves women at risk for sexual and reproductive health, so health teams should be able to detect these problems in order to intervene appropriately and effectively.

Factores familiares asociados al inicio sexual temprano en adolescentes consultantes en un centro de salud sexual y reproductiva en Santiago de Chile / Factors associated with early sexual activity among Chilean adolescents

Material and methods: We studied 4,971 adolescents of both sexes aged between 12 and 19 years, who consulted in a clinic for adolescents between the years 1990 and 2005. Several variables related to adolescent sexuality were considered. Uni and bivariate analysis were carried out and a model of stratified lineal regression per sex was fixed to explain the following variables: age at which sexual activity is initiated, number of sexual partners, time period between start of dating and the start of sexual activity along time. Results: The average age when men and women start their sexual activity was 15.7 and 15.5years, respectively. Along years and among women but not men, there was a reduction in the age of start of sexual activity and an increase in the number of sexual partners. The mean íapse between start of dating and the start of sexual activity in men and women was 6.2 and 7.5 months, respectively. This figure had an 11.696 and 13.9 percent reduction per year of study in females and males, respectively. Conclusions: There is an increasing expansion of sexual roles in adolescents, but certain patterns of contradictory conservative reasoning are maintained.
