RESUMO

BACKGROUND: Adolescents are more prone to develop health risk behaviors. Among these, early consumption of psychoactive drugs is relevant. AIM: To assess the association between early consumption of illicit drugs, tobacco and alcohol, suicide behaviors, risky sexual behaviors, eating habits and physical activity in school age adolescents from Valparaiso, Chile. MATERIAL AND METHODS: The online world survey of scholar health to identify the health risk behaviors was answered by 550 adolescents aged 15 to 18 years, from a public educational institution at Valparaiso, Chile. Results: Early consumption of alcohol, smoking and illicit drug use was reported by 59, 57 and 44% of respondents, respectively. The frequency of psychoactive drug consumption during the last month, risky sexual behaviors and missing breakfast was higher among those with an early onset of alcohol and illicit drug consumption and smoking. The frequency of suicidal risk behaviors and low consumption of fruits and vegetables was higher among those with an early onset of illicit drug use and smoking. A low physical activity level was associated with early smoking onset. Health risk behaviors were associated with early onset of alcohol and illicit drug consumption and smoking. CONCLUSIONS: Early onset of alcohol and illicit drug consumption and smoking is associated with health risk behaviors in Chilean adolescents.

RESUMO

BACKGROUND: Education on human sexuality was instituted in Eloisa Díaz Campus in 1946. From 2018 an online self-learning general education course on sexuality was started. AIM: To know the degree of knowledge about sexuality and the perception about the course of 586 students (42% women) who approved the course. MATERIAL AND METHODS: The Myths and False beliefs and Self-perception on sexuality tests were applied to students at the onset and the end of the course. They also anonymously evaluated the course. RESULTS: In the first assessment, the proportion of correct answers about sexuality and reproduction were 47 and 40% respectively. In the second assessment, 70% of respondents had open criteria about sexuality and 90% rejected traditional criteria. In the anonymous assessment, 95% estimated that the objectives of the course were accomplished. Its quality was considered good or excellent by 95% of respondents. CONCLUSIONS: This course was well accepted by students and corrects their knowledge gaps in sexuality. Despite the social unrest during 2019 and the pandemic during 2020, the course was successfully completed by most students.

RESUMO

Background: Adolescence is considered a nutritionally vulnerable period of life, since their eating habits are influenced by factors that can promote the consumption of non-nutritious food. Aim: To analyze the relation between eating habits, obesity, and the perception of Health-Related Quality of Life in school-aged adolescents. Material and Methods: A cross-sectional study of 550 adolescents aged 16 ± 1 years (60% women) attending a public education institution in Valparaíso, Chile. The Global School-based Student Health Survey (GSHS) for eating habits and the KIDSCREEN-27 survey for health-related quality of life were self-administered online. The answers were anonymous. A logistic regression analysis was conducted to evaluate the relationship between the variables, which was adjusted for age and sex. Results: Ten percent of men and 6% of women were obese. Those with an inadequate consumption of fruits had a worst perception of their physical well-being, autonomy and relationship with their parents. Psychological well-being and school environment were perceived worst among those that did not consume breakfast. Obese respondents also reported a poorest physical health. Conclusions: Inadequate eating habits and obesity have a negative effect of health-related quality of life among adolescents.

RESUMO

OBJETIVO: Evaluar la calidad de la educación sexual recibida en el contexto escolar y su asociación a conductas sexuales en adolescentes chilenos. MÉTODOS: Estudio transversal y analítico. La muestra correspondió a adolescentes de ambos sexos de 15 a 19 años, se obtuvo de una base de datos con representación nacional. Se evaluó la calidad de la educación sexual recibida en el contexto escolar como buena, regular y mala. Se realizó análisis descriptivo y de asociación entre las variables. Se calculó OR (Odds ratio) y RRR (Relative-risk ratios) ajustado por sexo, edad en años cumplidos, grupo socioeconómico y zona. RESULTADOS: La muestra correspondió a 1.049 adolescentes sexualmente activos, de estos el 21,83% correspondió al grupo con evaluación mala, 44,16% con evaluación regular y 34,01% con evaluación buena. La razón entre adolescentes que no usaron condón en la última relación sexual versus usaron condón, es 1,64 veces mayor en los adolescentes con evaluación mala de la educación sexual recibida (OR: 1,64; IC95%: 1,01 - 2,68). La razón entre adolescentes que tuvieron dos o más parejas sexuales en el último año versus ninguna o una, es 2,15 veces mayor en los adolescentes con evaluación mala de la educación sexual recibida (OR: 2,15; IC95%: 1,30 - 3,56). CONCLUSIÓN: Los participantes de este estudio evalúan la educación sexual recibida mayoritariamente como regular, existiendo una asociación con las conductas sexuales. Es importante realizar estudios en profundidad que permitan conocer por qué los adolescentes evalúan sólo como regular la educación sexual recibida en el sistema escolar.

OBJECTIVE: To evaluate the quality of the sexual education received in the school context and its association with sexual behaviors in Chilean adolescents. METHODS: Cross-sectional and analytical study. The sample corresponded to adolescents of both sexes from 15 to 19 years old, it was obtained from a database with national representation. The quality of the sexual education received in the school context was evaluated as good, regular and bad. Descriptive and association analysis were performed between the variables. OR (Odds ratio) and RRR (Relative-risk ratios) adjusted for sex, age in completed years, socioeconomic group and area were calculated. RESULTS: The sample corresponded to 1,049 sexually active adolescents, of these, 21.83% corresponded to the group with bad "Evaluation", 44.16% with regular "Evaluation" and 34.01% with good "Evaluation". The ratio among adolescents who did not use a condom in the last sexual relationship versus those who used a condom is 1.64 times higher in adolescents with a poor evaluation of sexual education received (OR: 1.64; 95% CI: 1.01 - 2.68). The ratio among adolescents who had two or more sexual partners in the last year versus those who had neither or one, is 2.15 times higher in adolescents with poor evaluation of sexual education received (OR: 2.15; 95% CI: 1.30 - 3.56). CONCLUSION: The participants of this study evaluate the sexual education received mostly as regular, with an association with sexual behaviors. It is important to conduct in-depth studies that allow us to know why adolescents evaluate the sexual education received in the school system as regular only.

RESUMO

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.

RESUMO

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.

ABSTRACT Introduction: Sexual satisfaction is an indicator of quality of life that has become more relevant in scientific research. Objective: To compare the level of sexual satisfaction, variables of couple relationship and sexual behavior of adult women and adolescents who are users of two university health care centers. Methods: Observational, transversal and analytical study of two groups: adult and adolescents women. Sexual satisfaction was measured by the New Sexual Satisfaction Scale (NSSS). A questionnaire was applied based on sociodemographic data, couple relationship and sexual behavior. Bivariate analysis and logistic regression were performed to evaluate the variables of couple relationship, sexual behavior and level of sexual satisfaction according to the group of adults or adolescents. Results: 348 women participated (174 adults and 174 adolescents). The average age of adults was 33 years (range 20-50) and adolescents 17 years (range 14-19). In the total trial 89.9% the most recent sexual experience occurred in the context of a relationship. 94,6% feel satisfied with their relationship. Adolescents have a higher level of sexual satisfaction than adults. Conclusions: When adult women feel satisfied with their relationship and sexual initiative is shared, the sexual satisfaction increases. In adolescents, sexual satisfaction increases when sexual activity occurs in a relationship context and when they have a higher frequency of sexual relations
