Intención de consumo de alcohol en adolescentes que cursan estudios en la enseñanza técnica profesional

Introducción: El consumo excesivo de bebidas alcohólicas por los adolescentes, constituye un problema de salud emergente, cuya solución ha devenido en prioridad mundial. El determinante inmediato para la ejecución de una conducta es la intención del individuo, por lo que es un momento preciso para aplicar acciones preventivas. Objetivos: Explorar la intención de consumo de alcohol y su relación con variables sociodemográficas y de consumo. Métodos: Se realizó un estudio descriptivo de corte transversal, con 143 adolescentes entre 15 y 18 años de edad, seleccionados mediante un muestreo aleatorio simple. Se les aplicó el cuestionario de intención de uso de alcohol. Resultados: El 84,6 % de los adolescentes había consumido alcohol; el 45,5 % tenía 18 años de edad y el 57,9 % eran varones. La edad de inicio del consumo fue de 15 años para el 41,3 %. El puntaje medio en la escala actitud fue mayor, de forma significativa, en los consumidores (p= 0,000). La actitud es la dimensión que más contribuyó a la iniciación en el consumo de alcohol (Wald= 14,56; p= 0,000). Conclusiones: Los adolescentes se caracterizan por ser en su mayoría consumidores de bebidas alcohólicas, con predominio del sexo masculino y una edad promedio de inicio del consumo de 15 años. La variable fundamental favorecedora de la intención de consumo de alcohol es la actitud positiva hacia el consumo, frecuentemente reforzada en el ambiente social y familiar.

Introduction: Excessive consumption of alcoholic beverages by adolescents, constitutes an emerging health problem, whose solution has become a global priority. The immediate determinant for the execution of a behavior is the intention of the individual, so it is a precise moment to apply preventive actions. Objectives: To explore the intention to consume alcohol and its relationship with sociodemographic and consumption variables. Methods: A descriptive cross-sectional study was carried out with 143 adolescents between 15 and 18 years of age, selected by simple random sampling. They were administered the alcohol use intention questionnaire. Results: 84.6% of the adolescents had consumed alcohol; 45.5% were 18 years old and 57.9% were male. The age of onset of consumption was 15 years for 41.3%. The mean score on the attitude scale was significantly higher in consumers (p= 0.000). Attitude is the dimension that contributed most to the initiation of alcohol consumption (Wald= 14.56; p= 0.000). Conclusions: Adolescents are characterized by being mostly consumers of alcoholic beverages, with a predominance of male sex and an average age of onset of consumption of 15 years. The fundamental variable favoring the intention to consume alcohol is the positive attitude towards consumption, frequently reinforced in the social and family environment.

Factores Psicológicos y Relaciónales Asociados a Episodios de Embriaguez en Adolescentes Escolares de Guadalajara, México / Psychological and Related Factors Associated with Drunkenness Episodes in Adolescent Students in Guadalajara, Mexico / Fatores Psicológicos e Relações Associados a Episódios de Embriaguez em Adolescentes Escolares de Guadalajara, México

Resumen El objetivo de este estudio fue asociar factores psicológicos y relaciónales vinculados a episodios de embriaguez en 1134 adolescentes escolares de Guadalajara, México. Se evaluaron diez factores psicológicos y relacionales. La variable de desenlace fue episodios de embriaguez durante el último mes. Se encontró una prevalencia de embriaguez de 26.5% con mayor consumo en hombres. Después del análisis de regresión logística los factores asociados a embriaguez fueron tabaquismo, alta autoestima, alta impulsividad, bajo locus de control interno, la presencia de estrés cotidiano y relación distante con el padre. La investigación concluye que los factores psicológicos y relacionales asociados a episodios de embriaguez hicieron referencia a un perfil de omnipotencia altamente influenciable, y al desapego emocional, por lo que el consumo excesivo de alcohol parece perfilarse como una estrategia de seguridad.

Abstract The aim of this study was to identify psychological and related factors linked with drunkenness episodes in 1134 adolescent students in Guadalajara, Mexico. The study evaluated ten psychological and related factors. The outcome variable was the number of episodes of drunkenness in the last month. We found 26.5% more episodes of drunkenness in men. A logistic regression analysis indicated that factors associated with drunkenness were smoking, high self-esteem, high impulsiveness, low self-control, presence of daily stress and distant relationship with father. The study concluded that the psychological and related factors associated with drunkenness episodes were related to a highly impressionable omnipotence profile and emotional indifference, with excessive consumption of alcohol as a safety strategy.

El consumo riesgoso y dañino de alcohol y sus factores predictivos en adolescentes estudiantes del bachillerato / Hazardous and harmful drinking among Mexican adolescents: prevalence and predictive factors

Alcohol is commonly used among adolescents in Mexico. In a representative survey of Mexico's general population, 30% of the teenagers reported current drinking, whereas 8% incurred in binge drinking (5 or more drinks per occasion) at least once during the last year. In addition, 3% reported three or more alcohol dependence symptoms over the last 12 months. In this Mexican age group, alcohol consumption importantly contributes to the most frequent causes of morbidity and mortality (e.g. accidents, violence, homicides, suicide and risky behaviors). Data from a representative survey of adolescents attending middle and high school in Mexico City suggests that adolescents attending Mexico's schools run a high risk for alcohol problems. In this study, prevalence of lifetime and current drinking, and of current binge drinking (5 or more drinks per occasion) were, respectively, 65.8%, 35.2%, and 23.8%. These rates are substantially higher than those described in teenagers from Mexico's general population. Furthermore, although among Mexico's general population the prevalence of drinking has traditionally been higher among male than female adolescents, no gender differences in prevalence of alcohol consumption have been reported among Mexican middle and high school students. This suggests that female adolescents in Mexico's schools have become equally exposed to drinking as their male counterparts. Despite these trends, there is a paucity of studies examining drinking patterns and their respective correlates among Mexican adolescents attending post-elementary education. To our knowledge, in this population, there are no published prevalence estimates of Hazardous and Harmful Drinking (HHD). HHD is defined as a pattern of alcohol consumption conferring to the individual a greater risk for health problems, or frankly conducive to medical or psychological complications (e.g. accidents, victimization, violence, alcohol dependence, liver cirrhosis and/or other medical complications). The Alcohol Use Disorders Identification Test (AUDIT), developed by the World Health Organization, is currently the only instrument specifically designed to identify HHD. Although the AUDIT was initially validated only among adult patients in primary care settings, this instrument has consistently shown to be valid and reliable in detecting alcohol problems in different populations, such as the adolescent population in many countries around the world. Given the public health implications of estimating the frequency of HHD among adolescents attending high school in Mexico, and given the importance of elucidating the variables influencing this problem, we decided to conduct the analysis presented here. To our knowledge, this is the first report published in the international literature on the prevalence of HHD among adolescents attending high school in a Latin American country. Objective In the study described here, derived from a Universidad Nacional Autónoma de México (UNAM) project entitled <>, we aimed at examining the frequency and risk factors for HHD among Mexican high school students. More specifically, our objectives were: 1. to determine the past-year prevalence of HHD among high school freshmen; and 2. to examine, in this population, the effects of demographic and family variables in the likelihood of HHD. Subjects and methods This study was a cross-sectional survey conducted at the beginning of the school year during the registration period between September 1st and September 30th, 2005. In 2005, a total of 34000 students were accepted to initiate college at the nine UNAM college campuses located in the Mexico City metropolitan area. Of these, 28784 students (87.4 %) (age=14.8 [±2.5] years; 51.0% women) consented in answering the survey and provided complete data. Consequently, 521 6 students (12.6%) were excluded from the analysis due to a lack of consent, incomplete data or their absence at the time of registration. We used the AUDIT to examine past-year prevalence of HHD. This self-report instrument includes 10 items that examine frequency and intensity of drinking (items 1-3), presence of alcohol dependence symptoms (items 4-6), and negative consequences of drinking (items 7-10), yielding a maximum possible score of 40 points. Among adult patients in primary care settings, it has been accepted that an AUDIT score of 0-7 points reflects safe levels of alcohol consumption, whereas a score of 8 points or higher indicates the presence of Hazardous and/or Harmful Drinking. It has been described however, that among adolescents, an AUDIT score of 3 points or higher reliably identifies those students experiencing this problem. In the analysis presented here, we separately examined and reported prevalence estimates and correlates for HHD using both AUDIT's cut-off scores (≥3 and ≥8). The AUDIT was administered at the same time that a wellness screening survey that the UNAM Medical Services routinely administer to all registering high school freshmen at the beginning of the school year. Questions in the wellness survey pertained students' medical and dental health, family medical history, immunizations, and use of tobacco and other drugs. In addition, demographic and socioeconomic information was obtained from a questionnaire also routinely administered by the UNAM registrar's office. This questionnaire included 37 items inquiring about gender, age, employment and marital status, monthly family income, parental education, place and type of residency, persons with whom the student resided, and questions on previous academic performance. We estimated the prevalence of HHD and their respective 95% confidence intervals (95% CI) in the total of the sample, and separately by age group, gender, working status, monthly family income, parental education, and by variables reflecting whether the students lived with their family, peers, or alone. These variables were modeled using simulated binary terms (0, 1). Subsequently, a multinomial logistic regression was used to examine the relationship between HHD and the demographic and socioeconomic variables listed above. Variables were entered simultaneously into the logistic regression equation. To summarize the level of risk of HHD conferred by significant variables in the logistic regression model, odds ratios (OR) and their respective 95% CI's were estimated. All the significant effects reported here were adjusted considering the effects of the remaining demographic and socioeconomic variables. Results Among the high school students examined here, the prevalence of HHD was 4.0% when an AUDIT cut-off score of ≥ 8 was used. When an AUDIT score of ≥3 was considered, a frequency of 1 7.2% was observed. Men (AUDIT ≥8: 5.4%; AUDIT ≥3: 21.4%) experienced this problem more frequently than women (AUDIT≥8: 2.6%; AUDIT≥3: 13.1%). The highest prevalence of HHD among men was observed in all age groups and regardless of working status, family income, parents' education, or regardless of the persons with whom the student reported to live with. Controlling for demographic and socioeconomic differences between men and women, we found that the risk of experiencing HHD among men was approximately two times higher than among women (OR's and 95% CI's for AUDIT's cut-off score ≥8 or ≥3, respectively 2.0[1.6-2.4] and 1.6[1.5-1.8]).

De acuerdo a la Encuesta Nacional de Adicciones (ENA) (Medina-Mora et al., 2003), de 1990 al 2002, la prevalencia en el consumo de alcohol durante los últimos 12 meses entre los jóvenes mexicanos de 12 a 17 años de edad, se elevó del 27.6% al 30%. De manera más reciente, la Encuesta de Estudiantes de Nivel Medio y Medio Superior de la Ciudad de México (EENMMS) (Villatoro et al., 2003), describió que el consumo alguna vez en la vida y el consumo durante el último mes de bebidas etílicas afectó respectivamente al 65.8% y al 35.2% de los estudiantes. Llama la atención que la frecuencia del consumo alguna vez en la vida reportada por la EENMMS es considerablemente mayor que la descrita en los adolescentes de la población general urbana (39.8%) por la ENA. Además, las diferencias de género reportadas por la ENA, en las que los hombres tradicionalmente beben con más frecuencia que las mujeres, no fueron encontradas por la EENMMS en la población estudiantil del nivel medio y medio superior. Hasta lo que nosotros sabemos, se desconoce cuál es la prevalencia en esta población de patrones de consumo problemático de alcohol como serían el consumo riesgoso y dañino (CRDA) o el consumo dependiente. Por lo que se desconoce si existen diferencias entre la población estudiantil y los adolescentes de la población general, en la prevalencia de estos problemas. El CRDA se define como un patrón de consumo de bebidas embriagantes, que se sitúa en un continuum de severidad, que coloca al sujeto en riesgo de desarrollar problemas de salud y/o que puede desembocar en francas complicaciones físicas y/o psicológicas (accidentes, victimización, violencia, dependencia al alcohol, etc.). Objetivo En el estudio que se presenta aquí, nos propusimos: 1) estimar la prevalencia durante el último año del CRDA en los estudiantes de primer ingreso al nivel bachillerato de la UNAM, y 2) evaluar la influencia de las variables sociodemográficas y familiares en el riesgo para el CRDA. Material y métodos El diseño del estudio fue el de una encuesta transversal en los estudiantes del primer año del bachillerato en el sistema escolarizado de la UNAM. Se estudiaron a 28 784 estudiantes (87.4 % de la población total). Se utilizó el Alcohol Use Disorders Identification Test (AUDIT) -versión en español para detectar el CRDA en la población adolescente. En este análisis empleamos tanto los puntos de corte recomendados para evaluar el CRDA en adultos (AUDIT≥8) como el puntaje recomendado para la población adolescente (AUDIT≥3). Se utilizaron porcentajes, promedios y desviaciones estándar para el análisis de las variables demográficas, y pruebas de contraste de medias (análisis de varianza) y de proporciones ( χ²) de acuerdo a la variable. Se utilizó la regresión logística multinomial para examinar la asociación de las variables demográficas y familiares con el CRDA. Se calcularon los odds ratios (OR) con intervalo de confianza al 95% para resumir el nivel de riesgo de ser afectado por el CRDA. Resultados Cuando se usó la definición del CRDA para la población adulta, se encontró que 4.0% de los estudiantes lo presentaron, frente a 1 7.2% cuando se utilizó el puntaje del AUDIT recomendado para los adolescentes. El riesgo de experimentar el CRDA fue casi dos veces mayor en los hombres que en las mujeres.
