Patrones de violencia en las relaciones de pareja en adolescentes: una revisión sistemática de la literatura / Patterns of Teen Dating Violence. A Systematic Review of the Literature

Resumen Un grupo creciente de investigaciones ha sugerido la existencia de diferentes patrones de violencia en las relaciones de pareja durante la adolescencia. El objetivo de este estudio fue revisar y sintetizar la evidencia científica respecto a patrones de violencia en las relaciones de pareja en adolescentes, a través de una revisión sistemática de la literatura. La búsqueda se realizó en las bases de datos Pubmed, Scopus, SCIELO, EBSCO, Web of Science, Sage Journals, Taylor and Francis Journals, Wiley, y el motor de búsqueda Google Académico; no hubo restricciones en el año de publicación. Se incluyeron investigaciones que analizaron la violencia desde una perspectiva centrada en la persona (e.g., uso de análisis de clases latentes). Para evaluar la calidad de los estudios transversales se usó la herramienta Axis de 20 ítems, y para los estudios longitudinales, la lista de verificación de Tooth et al. (2005) de 33 ítems. Se identificaron 212 estudios y después de elegir por criterios de elegibilidad, se incluyeron 27. Los patrones de violencia con mayor frecuencia fueron: violencia multiforme (34%), victimización o perpetración por violencia psicológica y física (26%), violencia bidireccional psicológica/verbal (26 °/o), baja violencia (26 °%) y alta violencia (23 °/o). Los patrones de violencia se relacionaron con diferentes variables tales como experiencias adversas en la infancia, variables sociodemográficas, relación familiar e indicadores de salud mental. Estos patrones evidencian que la violencia en las relaciones de pareja durante la adolescencia son un fenómeno complejo y multifactorial.

Abstract A growing body of research has suggested different patterns of teen dating violence. The aim of this study was to review and synthesize the scientific evidence on patterns of teen dating violence, through a systematic review of the literature. The search was conducted in the databases Pubmed, Scopus, SCIELO, EBSCO, Web of Science, Sage Journals, Taylor and Francis Journals, Wiley, and the Google Scholar search engine; there were no restrictions on the year of publication. Studies that indicate analyzing violence from a person-centered perspective (e.g., use of latent class analysis) were included. The 20-item Axis tool was used to assess the quality of the cross-sectional studies, and the 33-itemTooth et al. (2005) Checklist was used for longitudinal studies. Two hundred and twelve studies were identified and after screening for eligibility criteria, 27 studies were included. The most frequent patterns of violence were multiform violence (34%), victimization or perpetration by psychological and physical violence (26%), bidirectional psychological/verbal violence (26%), low violence (26%) and high violence (23%). Violence patterns were related to different variables such as adverse childhood experiences, sociodemographic variables, family relationship, and mental health indicators. These patterns show that teen dating violence is a complex and multifactorial phenomenon.

Patrones de victimización por violencia en el noviazgo y consumo de alcohol en adolescentes estudiantes del sur de Jalisco, México / Patterns of dating violence victimization and alcohol consumption among adolescent students from southern Jalisco, Mexico

Resumen Estudios sugieren la presencia de patrones de violencia en las relaciones de noviazgo durante la adolescencia. En la población adolescente mexicana se conoce poco sobre los patrones de abuso cara a cara y digital en el noviazgo y cómo pueden ser explicados por el consumo de alcohol. El objetivo de esta investigación fue identificar los patrones de victimización por abuso en las relaciones de noviazgo y determinar si el consumo de alcohol predice los patrones encontrados. Fue un estudio transversal con alcance explicativo. Participaron 398 adolescentes estudiantes (62.8% mujeres) de 15 a 18 años de edad (M = 16.1 años; DT = 1). Se usó un análisis de clases latentes y se encontraron tres clases: 1) violencia generalizada baja (45%), 2) violencia psicológica moderada y control digital alto (38%) y 3) violencia generalizada alta (17%). Se encontró que el consumo de alcohol se asoció con la pertenencia a la clase de violencia psicológica moderada y control digital alto (β = 0.48, p = .022) y con la pertenencia a la clase de violencia generalizada alta (β = 0.66, p = .004). Es importante considerar, en la generación de intervenciones, la existencia de patrones de violencia en el noviazgo en adolescentes y la influencia que tiene el consumo de alcohol sobre estos.

Abstract Studies suggest the existence of patterns of dating violence during adolescence. In the adolescent Mexican population, little is known about the patterns of face-to-face and cyber dating abuse and to what extent they can be explained by alcohol consumption. The aim of this research was to identify patterns of dating abuse victimization and to determine whether alcohol use predicts the patterns found. It was a cross-sectional study with an explanatory scope. A total of 398 adolescent students (62.8% women) from 15 to 18 years of age (M = 16.1 years; SD = 1) participated in the study. Latent class analysis was used, and three classes were found: 1) low generalized violence (45%); 2) moderate psychological violence and high digital control (38%); and 3) high generalized violence (17%). Alcohol consumption was found to be associated with the membership in the moderate psychological violence and high digital control (β = 0.48, p = .022) and were included in the high generalized violence class (β = 0.66, p = .004). It is important to consider, in the generation of interventions, the existence of patterns of violence in dating relationships among adolescents and the influence that alcohol consumption has on them.

Resultados: Se encontraron índices de ajuste aceptables en el análisis factorial confirmatorio, además se encontró validez convergente y discriminante de los factores, excepto entre los factores de victimización y perpetración de Agresión Directa. Se encontró evidencia de validez divergente con la calidad de vida y convergente con comportamientos de riesgo. La fiabilidad total fue superior a .87. Conclusiones: Los hallazgos sugieren que el CDAQ puede ser un cuestionario útil para evaluar el abuso digital en las relaciones de pareja en jóvenes mexicanos.

Introduction: Cyber dating abuse is a public health problem that requires valid and reliable evaluations. The objective of this study was to cross-culturally adapt and evaluate the psychometric properties of the Cyber Dating Abuse Questionnaire (CDAQ) for Mexican youth. Method: 1158 young students from 18 to 24 years old participated, 62.9 % were women. In the verification of the linguistic equivalence phase, four words from the original version in Spanish were adapted. Results: Acceptable fit indices were found in the confirmatory factor analysis, in addition, convergent and discriminant validity of the factors was found, except between the factors of victimization and perpetration of Direct Aggression. Evidence of divergent validity was found with quality of life and convergence with risk behaviors. Total reliability was greater than .87. Conclusions: The findings suggest that CDAQ could be a useful questionnaire to assess cyber dating abuse among young Mexicans.

Relación entre el abuso cara a cara y digital en el noviazgo con la calidad de vida relacionada con la salud en adolescentes mexicanos / Relationship between face-to-face and digital dating abuse with health-related quality of life among Mexican adolescents / Relação entre o abuso presencial e digital no namoro com qualidade de vida relacionada à saúde em adolescentes mexicanos

El objetivo de esta investigación fue identificar si existe relación entre la victimización por abuso cara a cara y digital en el noviazgo con la calidad de vida relacionada con la salud (CVRS) en estudiantes adolescentes, ajustando por sexo. Participaron 398 estudiantes de entre 15 y 18 años de edad (62,8% mujeres). Se aplicaron las siguientes escalas adaptadas a población adolescente mexicana: Violence in Adolescents' Dating Relationships Inventory, Cyber Dating Abuse Questionnaire y el KIDSCREEN-10. Se encontró que el 55,5% reportó haber sido víctima de abuso cara a cara y digital. Los puntajes de CVRS fueron menores para las mujeres a diferencia de los hombres. Mediante un modelo de ecuaciones estructurales se encontró una asociación negativa, estadísticamente significativa y con magnitud moderada entre el abuso en el noviazgo (cara a cara y digital) y la CVRS. Los resultados sugieren que mientras mayor sea el nivel de victimización por abuso en las relaciones de noviazgo tanto cara a cara como digital, menor será la CVRS en las y los adolescentes estudiantes. Los resultados de este estudio muestran la importancia de considerar tanto el abuso cara a cara como el digital cuando se analiza el efecto de la violencia en el noviazgo sobre la CVRS.

The purpose of this research was to identify whether there is a relationship between face-to-face and digital dating abuse victimization with health-related quality of life (HRQoL) among adolescent students, adjusted for sex. Three hundred ninety-eight students of 15 to 18 years of age (62.8% female) participated. The following scales adapted to the Mexican adolescent population were applied: Violence in Adolescents' Dating Relationships Inventory, Cyber Dating Abuse Questionnaire and the KIDSCREEN-10. It was found that 55.5% of the respondents reported having been victims of face-to-face and digital abuse. HRQoL scores were lower for women than for men. Using structural equation modeling, a negative, statistically significant association of moderate magnitude was found between dating abuse (face-to-face and digital) and HRQoL. The results suggest that the higher the level of abuse victimization in both face-to-face and digital dating relationships, the lower the HRQoL of adolescent students. The results of this study show the relevance of considering both face-to-face and digital abuse when analyzing the effect of dating violence on the HRQoL.

O objetivo desta pesquisa foi identificar se existe uma relação entre a vitimização presencial, o namoro digital e a qualidade de vida relacionada à saúde (QVRS) em estudantes adolescentes, ajustado por sexo. Participaram 398 estudantes com idades entre 15 e 18 anos (62,8% mulheres). Aplicaram-se as seguintes escalas adaptadas à população adolescente mexicana: Violence in Adolescents' Dating Relationships Inventory, Cyber Dating Abuse Questionnaire e o KIDSCREEN-10. Verificou-se que 55,5% relataram terem sido vítimas de abuso presencial e digital. A pontuação da QVRS foi menor para as mulheres, em oposição aos homens. Através de um modelo de equações estruturais foi encontrada uma associação negativa, estatisticamente significativa e com magnitude moderada entre o abuso no namoro (presencial e digital) e a QVRS. Os resultados sugerem que quanto maior o nível de vitimização de abuso, tanto nas relações de namoro presencial quanto nos digitais, menor será o QVRS dos estudantes adolescentes. Os resultados deste estudo mostram a importância de considerar tanto o abuso presencial quanto o digital ao analisar o efeito da violência no namoro na QVRS.

Comportamientos de riesgo de suicidio y calidad de vida relacionada con la salud en estudiantes que ingresaron a una universidad mexicana / Suicide-related behavior and health-related quality of life among first-year university students in a Mexican university

Resumen El objetivo fue determinar si existe asociación entre comportamientos de riesgo de suicidio (CRS) y menor calidad de vida relacionada con la salud (CVRS) y si esta asociación es independiente del consumo de sustancias, violencia y variables sociodemográficas. Estudio transversal, con 1229 estudiantes universitarios mexicanos; 62.4% mujeres y 37.6% hombres, edad 18.2 ± .6 años. Se aplicaron los instrumentos YRBS y KIDSCREEN-52. Presentaron desesperanza 14.2%, ideación suicida (IS) 4.7%, planeación suicida (PS) 4.0% e intento suicida 2.3%. Modelos de regresión logística múltiple muestran que la desesperanza aumentó la posibilidad de menor puntuación en todos los dominios de CVRS excepto en recursos económicos, con odds ratio OR (IC95%) que van de 1.5 (1.0-2.3) para autonomía, hasta 4.6 (3.1-6.8) para estado de ánimo. La IS incrementó la posibilidad de menor puntuación en relación con los padres y vida familiar (3.9, 1.7-8.9) y en amigos y apoyo social (2.9, 1.3-6.4). La PS aumentó la posibilidad de menor bienestar físico (2.7, 1.2-6.1) y psicológico (3.1, 1.3-7.2). En estudiantes mexicanos la CVRS se asocia a los CRS aún después de ajustar por consumo de sustancias y violencia. Se destaca que la desesperanza se asocia negativamente a los distintos dominios de la CVRS de los estudiantes.

Abstract The objective was to determine if suicide-related behavior (SRB) and health-related quality of life (HRQL) are associated and whether this association is independent of substance use, violence, and sociodemographic variables. It involved a cross-sectional study with 1,229 Mexican university students: 62.4% women; 37.6% men; age 18.2± .6 years. The YRBS and KISDSCREEN questionnaires were applied. The results were as follows: 14.2% students reported despair; 4.7% had suicidal ideation (SI); 4% had suicidal tendencies (ST); and 2.3% had attempted suicide. Multiple logistic regression models show that despair increased the possibility of lower scores in all HRQL domains except economic resources with odds ratio OR (CI 95%) ranging from 1.5 (1.0-2.3) for autonomy to 4.6 (3.1-6.8) for state of mind. The SI increased the possibility of a lower score in relationships with parents and family life (3.9, 1.7-8.9) and in friends and social support (2.9, 1.3-6.4). The ST increased the possibility for lower physical (2.7, 1.2-6.1) and psychological well-being (3.1, 1.3-7.2). HRQL is associated with SRB among Mexican students even after adjustment for substance use and violence. It highlights the fact that despair is negatively associated with different domains of the HRQL of the students.

Instrumentos de evaluación de la autolesión no suicida en adolescentes 1990-2016: una revisión sistemática / Assessment tools of non-suicidal self-injury in adolescents 1990-2016: a systematic review

Resumen El propósito de esta revisión sistemática fue identificar los instrumentos creados o adaptados para evaluar la autolesión no suicida en adolescentes. Se utilizó la metodología PRISMA. Dos revisores independientes analizaron las propiedades psicométricas de los instrumentos publicados en inglés o español desde 1990 a 2016 considerando criterios de calidad estandarizados. Las bases utilizadas fueron PsycINFO, PubMed, ISI Web of Knowledge, Scopus, SciELO, ScienceDirect y EBSCO. Se seleccionaron 18 estudios que crearon o adaptaron 11 instrumentos. La mayoría desarrollados en Estados Unidos y Canadá y ninguno en América Latina. Varios estudios no presentan evidencia de las propiedades psicométricas de los instrumentos. Siete de los 18 estudios obtuvieron al menos una puntuación positiva. El ABUSI y el ISSIQ-A obtuvieron la mayor cantidad de puntuaciones positivas. Las limitaciones de este estudio fueron que la búsqueda se realizó solamente en siete bases de datos y en los idiomas inglés y español. Se sugiere mejorar el reporte de las propiedades psicométricas de los instrumentos de autolesión no suicida en adolescentes y desarrollar adaptaciones a países de América Latina que permitan hacer comparaciones internacionales.

Abstract The purpose of this systematic review was to identify the instruments created or adapted to assess non-suicidal self-injury (NSSI) among adolescents. The Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) methodology was used. Two individual reviewers analyzed the psychometric properties of instruments published in English or Spanish from 1990 to 2016 considering standardized quality criteria. The PsycINFO, PubMed, ISI Web of Knowledge, Scopus, SciELO, ScienceDirect, and EBSCO databases were consulted. Eighteen studies that created or adapted 11 instruments were selected. Most were developed in the United States or Canada, and none were developed in Latin America. Several studies presented no evidence of the psychometric properties of their instruments. Seven of the 18 studies obtained at least one positive score. The Alexian Brothers Urge to Self-Injure Scale (ABUSI) and the Impulse, Self-harm, and Suicide Ideation Questionnaire for Adolescents (ISSIQ-A) obtained the highest positive scores. The limitation of this study is that only seven databases were employed for the literature search in English and Spanish. The reporting of the psychometric properties of NSSI instruments among adolescents should be improved, and adaptations to Latin American countries should be developed for international comparisons.

Revisión sistemática de instrumentos de violencia en el noviazgo en Iberoamérica y evaluación de sus propiedades de medida / Systematic review of dating violence questionnaires in Ibero-America and evaluation of their measurement properties

Resumen Ser una víctima o perpetrador de violencia en el noviazgo se ha asociado con mala salud mental, consumo de sustancias y riesgos sexuales. El objetivo fue realizar una revisión sistemática y evaluar la calidad de las propiedades de medida de instrumentos de violencia en el noviazgo, creados o adaptados en Iberoamérica de 1981 a 2017, para población de 12 a 29 años y publicados en español, inglés, portugués o francés. La búsqueda se realizó en PubMed, ISI Web of Knowledge, EBSCO, ScienceDirect, SCOPUS, SciELO y búsquedas manuales. Dos investigadores independientes llevaron a cabo tanto la revisión sistemática como la evaluación de propiedades métricas. De 5,812 artículos identificados, 22 estudios con 16 instrumentos diferentes de violencia en el noviazgo fueron incluidos. En general, hubo evidencia de consistencia interna, validez de contenido y validez de constructo de los instrumentos y ningún estudio presentó evidencia de validez de criterio, reproducibilidad, sensibilidad y efecto piso techo. El 42% de las adaptaciones reportaron traducción, retro traducción, comité de expertos en la traducción y pilotaje. Las puntuaciones más altas las recibieron dos instrumentos creados, CMN y VADRI/España-México y dos adaptaciones del mismo instrumento CTS/Brasil-México .

Abstract Being a victim or perpetrator of dating violence has been associated with poor mental health, substance abuse, and sexual risk behaviors. The aim of this study was to carry out a systematic review and to evaluate the quality of the measurement properties of dating violence questionnaires, created or adapted in Ibero-America from 1981 to 2017, for a population aged 12 to 29 years and published in Spanish, English, Portuguese or French. The search was conducted in PubMed, ISI Web of Knowledge, EBSCO, ScienceDirect, SCOPUS, SciELO and included manual searches. Two independent researchers conducted both the systematic review and the evaluation of measurement properties. Of 5,812 articles identified, 22 studies involving 16 different questionnaires of dating violence were included. In general, the questionnaires showed evidence of internal consistency, content validity and construct validity, although no study presented evidence of criterion validity, reproducibility, sensitivity, or floor and ceiling effects. Among the cross-cultural adaptations, 42% of them included translation, back translation, committee of experts in translation and piloting. Two questionnaires created, CMN and VADRI/Spain-Mexico and two adaptations of the same questionnaire CTS/Brazil-Mexico received the highest scores .

Escala de Estimación del Consumo de Alimentos y Bebidas para Niños: Evaluación de sus propiedades psicométricas / Estimation of Food and Beverages Intake Scale for Children: Evaluation of psychometric properties

Resumen Las estrategias para disminuir el sobrepeso y la obesidad no han tenido el impacto esperado. Se requiere desarrollar mayor conocimiento sobre las variables estimación del alimento y frecuencia de consumo. Por lo tanto, el propósito de este estudio fue examinar las propiedades psicométricas de un instrumento dirigido a evaluar la estimación de alimentos (EAL) y su frecuencia de consumo (FRC) en niños. Participaron 1,090 niños y niñas de 9 años de edad de la región Sur de Jalisco (México), quienes completaron la Escala de Estimación y Consumo de Alimentos en Niños (ECA-N), que consta de dos secciones: EAL y FRC. El análisis factorial exploratorio realizado con 545 de los participantes derivó tres factores para cada sección, mismos que posteriormente fueron corroborados con base a dos análisis factoriales confirmatorios, uno por sección, practicados con la segunda mitad de la muestra (n = 545). Ambos modelos registraron adecuados índices de bondad de ajuste. La versión final de la ECA-N, con 23 ítems, mostró poseer adecuada consistencia interna en sus dos secciones: EAL (α = .86) y FRC (α = .84). Se discute sobre la necesidad de extender el análisis de las propiedades psicométricas de la ECA-N en niños de otras regiones del país.

Abstract The strategies to reduce overweight and obesity have not had the expected impact. It is necessary to develop greater knowledge regard food estimation and intake frequency. Therefore, the purpose of this study was to examine the psychometric properties of an instrument aimed at the evaluation of meals (EM) and its intake frequency (IFR) in children. A total of 1,090 9-year-old boys and girls from the South region of Jalisco (Mexico) answered the Scale of Estimation and Consumption of Foods in Children, which consists of two sections: EM and IFR. The exploratory factor analysis carried out with 545 participants derived three factors for each section, which were subsequently corroborated based on two confirmatory factor analyses, one per section, performed with the second half of the sample (n = 545). Both models registered some goodness of fit indexes. The final version of the scale, with 23 items, showed appropriate internal consistency in its both sections: EM (α = .86) and IFR (α = .84). The need to extend the analysis of the psychometric properties of the scale in children from other regions of the country is discussed.

Bullying and health-related quality of life in children and adolescent Mexican students / "Bullying" e qualidade de vida relacionada com a saúde de crianças e adolescentes escolares mexicanos

Abstract Previous studies have reported a relationship between being a victim of bullying, but no studies have been carried out with Mexican students; notwithstanding the high scores of bullying in Mexico in international rankings. The objective of this study was to analyze the association between being a victim of bullying and lower HRQoL among schoolchildren and adolescents in Mexico. This cross-sectional and correlational study involved 2225 students from 22 elementary, middle and high schools. HRQoL was assessed with the KIDSCREEN-10 questionnaire and bullying with the social adaptation dimension of KIDSCREEN-52. Bivariate associations were evaluated, and a multivariate logistic regression was utilized. The prevalence of victims of bullying was 17.3%. Being a victim of bullying was double the risk of having a lower HRQoL than not being a victim after adjusting for health perception, gender and age, OR 2.3 (1.7-3.1). As the Wilson and Cleary Model of Quality of Life explains, individual characteristics, such as, being a victim of bullying are associated with quality of life. Similar findings in the existing literature imply that bullying is a global phenomenon that impacts the victimized child or adolescent's life in different ways.

Resumo Pesquisas prévias informaram que ser vítima de "bullying" se associa à menor Qualidade de Vida Relacionada com a Saúde (QVRS); mas nenhuma foi realizada em estudantes Mexicanos apesar dos altos índices de "bullying" mostrados para o México nos rankings internacionais. O objetivo deste estudo foi analisar a associação entre ser vítima de "bullying" e QVRS. Este estudo transversal e de correlação incluiu 2225 crianças e adolescentes de 22 escolas de nível básico, médio básico e médio superior. A QVRS foi avaliada com o questionário KIDSCREEN-10 e o "bullying" com a dimensão de aceitação social do KIDSCREEN-52. Analisaram-se as associações bivariadas, verificou-se confusão e interação, e utilizou-se regressão logística multivariável. A prevalência de vítimas de "bullying" foi de 17.3%. Ser vítima de "bullying" obteve um risco de mais do dobro de QVRS inferior que não ser vítima, depois de ajustar pela percepção de saúde, gênero e idade, OR 2.3 (1.7-3.1). No mesmo sentido que o referido pelo Modelo de Wilson e Cleary, em estudantes mexicanos com características individuais como ser vítima de "bullying", associam-se à QVRS, descoberta similar ao encontrado na literatura existente o que implica que o "bullying" é um fenômeno global que se reflete em diferentes aspectos da vida em crianças e adolescentes vitimizados.

Uso de sustancias psicoactivas y calidad de vida relacionada con la salud en adolescentes escolarizados / Psychoactive substances use and health-related quality of life among school age adolescents

Background The use of psychoactive substances among adolescents is a major social and public health concern. Aim To analyze association of substance abuse and multiple drug use with health-related quality of life (HRQOL) in adolescents attending a high school in Valparaiso, Chile. Material and Methods Analytical cross-sectional study conducted in a sample of adolescents attending high school. HRQOL was assessed using KIDSCREEN-52 questionnaire and substance use was measured using the Global school-based student health survey. Participants had to complete online, self-administered, anonymous questionnaires. Multiple logistic regression analyses were conducted to calculate Odd ratios. Results A total of 550 adolescents aged 16 ± 1 years old completed the questionnaires. Thirty nine percent consumed alcohol during the last month, 31% smoked, 33% used marijuana and 33% admitted the use of multiple drugs. High-risk alcohol consumption was associated with a lower perception of psychological well-being, self-perception and school environment. This last dimension was affected in those who admitted marijuana use during the last month. Multiple drug use (three substances) was associated with a lower perception of physical and psychological well-being, self-perception, relationship with parents, family life and school environment. Conclusions High-risk alcohol consumption and multiple drug use (three substances) have a negative impact on the HRQOL of school age adolescents.

Adaptación transcultural del cuestionario KIDSCREEN para medir calidad de vida relacionada con la salud en población mexicana de 8 a 18 años / Cross-cultural adaptation of the KIDSCREEN questionnaire to measure health-related quality of life in the 8 to18 year-old Mexican population

Con el objeto de adaptar culturalmente el cuestionario KIDSCREEN-52 a adolescentes mexicanos de 8 a 18 años, y analizar su fiabilidad y validez, se realizó la traducción del cuestionario del inglés al español y una retro traducción. Se realizaron entrevistas cognitivas y un análisis factorial confirmatorio (AFC) para verificar la validez del contenido del cuestionario. Se compararon las puntuaciones de las dimensiones siguiendo los mismos criterios que en otras versiones (ej. Argentina) para analizar la validez de constructo, y se verificó la fiabilidad. La validez del contenido mantuvo las características del cuestionario original. El AFC confirmó la estructura de las 10 dimensiones originales. Dos escalas mostraron efecto techo. La consistencia interna del instrumento fue aceptable (rango 0,5-0,86) y la reproducibilidad obtuvo coeficientes bajos en 5 dimensiones (0,22-0,78). La versión mexicana del cuestionario KIDSCREEN-52 es equivalente al original en términos de contenido, estructura, y validez de constructo. En conclusión, el instrumento KIDSCREEN-52 es adecuado para aplicarse en población mexicana de estudiantes de 8 a 18 años. Son necesarios nuevos estudios para explorar su aplicación en contextos clínicos.

The scope of this study was to develop the culturally-adapted version of the KIDSCREEN-52 questionnaire for Mexican adolescents aged 8 to 18, and to analyze its reliability and validity. A translation and back translation was carried out from English to Spanish and vice versa. Cognitive interviews were conducted and confirmatory factor analysis (CFA) was used to verify the content validity of the questionnaire. Based on previous studies (i.e. the Argentinian version) mean scores of dimensions were compared to assess construct validity. Reliability was also analyzed. The results showed that the content validity of the version retained the original concepts, duly adapted to the Mexican culture and language. The AFC confirmed the structure of the 10 original dimensions. Two scales achieved the ceiling effect. The instrument's internal consistency was acceptable (ranged from 0.5 to 0.86), and reproducibility obtained low coefficients in 5 dimensions (0.22 to 0.78). The Mexican KIDSCREEN-52 version is equivalent to the original in terms of content, structure, and construct validity. The conclusion was that theKIDSCREEN -52 tool is suitable for application in the Mexican population aged 8 to 18. Further studies are needed to explore its application in clinical settings.

Actividad física, conductas sedentarias y calidad de vida en adolescentes universitarios de Ciudad Guzmán, Jalisco, México / Physical activity, sedentary behavior and quality of life in undergraduate adolescents of Ciudad Guzman, State of Jalisco, Mexico

Con el objeto de evaluar la asociación de la actividad física y conductas sedentarias con la calidad de vida en universitarios en Ciudad Guzmán, Jalisco, México, se estudiaron 881 adolescentes de 17-19 años de edad. Se utilizaron los cuestionarios en línea: Youth Quality of Life Instrument Research versión y el Youth Risk Behavior Survey. Se obtuvo razón de momios [RM] mediante regresión logística simple y múltiple. El número de días de actividad física se relacionó con el índice total superior, dominios general superior, personal superior y ambiental superior. Jugar en > 2 equipos deportivos se relacionó con el índice total superior, dominio general superior, dominio personal superior y dominio ambiental superior. Tener 4-5 clases de educación física a la semana se relacionó con el dominio general superior. Pasar dos o menos horas al día frente a la pantalla se relacionó con el dominio relacional superior. En conclusión, en los universitarios adolescentes mexicanos se asoció a indicadores de mejor calidad de vida, el realizar actividad física 4 o más días a la semana, asistir a clases de educación física 4 o 5 semanales, participar en 2 o más equipos deportivos y pasar menos de 2 horas diarias horas frente a pantallas en actividades recreativas.

With the aim of evaluating the association between physical activity and sedentary behavior with quality of life (QoL) in undergraduate students of Ciudad Guzman, state of Jalisco, Mexico, a total of 881 adolescents aged between 17 and 19 were studied. Online questionnaires were used, namely the research version of the Youth Quality of Life Instrument and the Youth Risk Behavior Survey. Odd ratios (OR) were obtained using simple and multivariate logistic regression analysis. The number of days with physical activity was related to a higher total perceptual score, higher general QoL domain, higher self domain as well as higher environment domain. Playing in > 2 sports teams was related to a higher total perceptual score, higher general QoL domain, higher self domain as well as higher environment domain. Having 4-5 physical education classes/week was related with a higher general QoL domain. Limiting recreational screen time to < 2 hours/day was related with a higher relationship domain. In conclusion, in Mexican undergraduate adolescent students, higher QoL was associated with: physical activity at least 4 days/week; physical education classes 4 or more days/week; playing in 2 or more sports teams and limiting recreational screen time to 2 hours or less.

Sobrepeso medido por IMC o percibido y comportamientos de control del peso en adolescentes universitarios de Ciudad Guzmán, Jalisco, México

El objetivo fue evaluar las asociaciones entre comportamientos de control de peso y sobrepeso medido por IMC, sobrepeso percibido o percepción errónea del peso en adolescentes por género. Participaron 492 adolescentes universitarios de 17 a 19 años de edad. Se utilizó un cuestionario auto aplicado en línea y se midió peso y estatura. Los análisis estadísticos incluyeron kappa ponderada y regresión logística multivariada. La concordancia entre el peso percibido y el medido por IMC fue 78.7% y la kappa ponderada=0.62. Los adolescentes que percibieron sobrepeso intentaron con más frecuencia bajar de peso, hacer ejercicio y comer menos alimentos que los que tenían sobrepeso medido por IMC. Una cuarta parte intentó bajarlo aún sin percibir o tener sobrepeso real. La posibilidad de tratar de bajar de peso fue mayor en hombres y mujeres con sobrepeso percibido (RM=18.7, IC 95% 6.3-55.3 y RM=10.4, IC 95% 4.5-24.2 respectivamente) y en mujeres que sobrestimaron el peso corporal (RM =6.0, IC 95% 2.8- 12.7). Hubo menos posibilidad de tratar de bajar peso cuando se subestimó el peso en hombres (RM = 0.03, IC 95% 0.01-0.12) y mujeres (RM=0.19, IC 95% 0.05-0.70). En conclusión, el comportamiento de bajar de peso se explica mejor en adolescentes en ambos géneros que percibían sobre peso y en mujeres que lo sobre estimaban, mientras que los hombres intentaron menos bajarlo si subestimaban su peso.

Perceived or BMI-measured overweight and weight controlbehaviors in undergraduate adolescents from Ciudad Guzmán, Jalisco, México. The aim was to evaluate associations between weight control behaviorsand overweight measured by BMI, overweight perception or inaccurate weight perception. 492 undergraduate adolescents from 17 to 19 years old participated in the study. A self-administered questionnaire on line was applied and weight and height were measured. Statistical analysis included weighted kappa and multivariate logistic regression. The concordance between weight perception and that evaluated by BMI was 78.7%, weight kappa = 0.62. Adolescents who perceived overweight tried to lose weight, exercised and ate less food more frequently than those who were overweight evaluated by BMI. A quarter tried to lose weight eventhough they did not perceive or were actually overweight.The odds of trying to lose weight were higher in men and women who perceived overweight (OR = 18.7,CI 95% 6.3-55.3and OR = 10.4, IC 95% 4.5-24.2, respectively) andwomen who overestimated overweight (OR = 6.0, CI 95% 2.8-12.7).The odds of tying to lose weight when weight was underestimated were less in men (OR = 0.03, CI 95% 0.01-0.12) and women (OR = 0.19, IC 95% 0.05-0.70). In conclusion the behavior of trying to lose weight was better explained among adolescents of both genders who perceived overweight and among girls who overestimated it.

Percepción del peso corporal, comportamiento de control de peso y calidad de vida en adolescentes mexicanos estudiantes de secundaria / Body weight perception, weight control behavior and quality of life in Mexican adolescents of secondary school

Este estudio transversal analizó la asociación de la percepción del peso corporal y el comportamiento alimentario de control de peso con la calidad de vida (CV) por género, en 563 estudiantes de secundaria (edad x‾ = 13.3, DE = 0.94) de todos los grados de nueve secundarias de la región del sur de Jalisco realizado en 2010. Eran 51.9% varones, 19.8% del total trabajaban. Se auto-administró en línea un cuestionario de CV (YQOL-R) módulo perceptual, y cinco ítems acerca del peso adaptados del 2009 Middle School YRBS. Estadística: chi cuadrada, t de Student, p de Spearman y ANOVA, T2 de Tamhane. Resultados: CV más alta para peso percibido cercano al correcto, respecto a bajo peso y sobrepeso; correlación negativa entre CV y percepción del peso (sobrepeso r s = -.22; bajo peso r s = -.16); CV más baja en quienes trataban de mantenerse en su peso en muestra total y en mujeres respecto a las que querían mantenerlo. Concluimos que el comportamiento alimentario está asociado de manera importante a la percepción del peso y ambos a la calidad de vida, y el género es fundamental para comprender las variables estudiadas.

This cross-sectional study analyzed by gender the association between body weight perception and weight control behavior with quality of life (QL) in 563 middle school students (age x‾ = 13.3, SD = 0.94), from all grades of nine middle schools of South region of Jalisco state realized in 2010. There were 51.9% boys and 19.8% worked. A self-administered questionnaire on line was used (YQOL-R), perceptual module, and five items of body weight adapted from 2009 Middle School YRBS. Statistical analysis included chi squared, Student t test, Spearman correlation, ANOVA and Tamhane's T2. Results: QOL was higher in normal weight perception category than low weight or overweight perception categories; a negative correlation between QOL and weight perception was observed (overweight r s = -.22; low weight r s = -.16); QOL was lower in those who tried to maintain weight in total sample and in girls in relation to those who tried to maintained it. We concluded that weight control behavior is associated with weight perception and both are associated with quality of life. Gender was important to understand the variables studied.

Calidad de vida, según percepción y comportamientos de control del peso por género, en estudiantes universitarios adolescentes en México / Quality of life according to self-perceived weight, weight control behaviors, and gender among adolescent university students in Mexico

El objetivo de este estudio fue analizar la calidad de vida (CV), según auto percepción del peso corporal y comportamientos de control de peso, por género, en 2.401 estudiantes de 17 a 19 años de primer ingreso en un centro universitario en México del 2007 al 2009; 61,9 por ciento mujeres, 80,6 por ciento no trabajaban y 99,2 por ciento solteros. Se auto administró en línea un cuestionario genérico de CV (YQOL-R) módulo perceptual, y siete ítems acerca del peso adaptados del YRBS 2007. Se observó que un 52 por ciento de mujeres y un 31,7 por ciento de hombres trataba de bajar de peso. CV más alta para peso cercano al correcto, quienes trataban de mantenerse en su peso y los que hacían ejercicio; CV más baja para quienes reportaron mucho sobrepeso, mujeres que trataban de bajar de peso, comían menos, dejaban de comer, hacían dieta sin supervisión, vomitaban o tomaban laxantes. En mujeres la CV fue diferente si trataban de mantenerse, subir o bajar de peso; en hombres sólo al tratar de subir. Esta información puede ser de utilidad para procesos educativos, programas de prevención y para evaluar las intervenciones.

The aim of this study was to analyze quality of life (QoL) according to self-perceived weight and weight control behaviors, by gender. The sample consisted of 2,401 adolescent students (17-19 years of age) enrolled from 2007 to 2009 at a Mexican university; 61.9 percent were women, 19.4 percent worked, and 99.2 percent were single. An online self-administered questionnaire was used that included the perceptual module of the YQOL-R and seven items on body weight, adapted from YRBS 2007. RESULTS: 52 percent of women and 31.7 percent of men were attempting to lose weight. The highest QoL scores were in students who felt they were near the right weight, those who were attempting to maintain the same weight, and those who exercised. Lowest QoL was reported by those who considered themselves overweight, were trying to lose weight, were eating less, were skipping meals, or were using unsupervised dieting, vomiting, or laxatives. In women, QoL differed between those maintaining the same weight, gaining weight, and losing weight, while QoL in men only differed for those attempting to gain weight. The findings could be useful in educational processes, preventive programs, and assessment of interventions.
