          Abstract

          Resumen Introducción: Las principales conductas de riesgo para el desarrollo de los trastornos de la conducta alimentaria (TCA) han proliferado y su frecuencia es preocupante en adolescentes. Resulta de gran interés contar con instrumentos psicométrica y culturalmente válidos para detectar de forma temprana los TCA. Por ello, el objetivo de la presente investigación fue estudiar la validez de constructo y confiabilidad del Cuestionario Breve de Conductas Alimentarias de Riesgo (CBCAR) en población michoacana. Metodología: Se realizó un análisis factorial confirmatorio (AFC) y un análisis de consistencia interna de la CBCAR aplicada a 1.185 universitarios. Resultados: Se analizó el ajuste del modelo de tres factores a través del AFC, en la muestra total y las submuestras por sexo, se observó un ajuste aceptable, aunque algo peor en la muestra de hombres. El Alfa de Cronbach para la escala total fue de 0,76 y los valores para las subescalas derivadas también fueron aceptables. Conclusiones: Se concluye que el instrumento es adecuado para población universitaria michoacana y hasta un 30,8% de la muestra obtuvo puntuaciones que sugieren riesgo de TCA.

          Abstract Introduction: The main risk behaviors for the development of eating disorders (ED) have proliferated and their frequency is worrying in adolescents. It is of great interest to have instruments psychometrically and culturally proper to provide the earliest detection of ED. Therefore, the objective of the present investigation was studying the construct validity and reliability of the Brief Questionnaire of Risk Eating Behaviors (BQREB) for Michoacan population. Methodology: A confirmatory factor analysis (CFA) and internal consistency analysis was performed at the scale applied to 1,185 university students. Results: The adjustment of three-factor model was analyzed through the CFA, in the total sample and the subsamples by sex, an acceptable adjustment was observed, although something worse in the men’s subsample. The Cronbach’s Alpha for the total scale was 0.76 and the values of the subscales were also acceptable. Conclusions: It is concluded that the instrument is suitable for Michoacan university population and up to 30.8% of the sample obtained scores that suggest a risk of ED.

            Dieting and disordered eating behaviors from adolescence to young adulthood: findings from a 10-year longitudinal study.

            Disordered eating behaviors are prevalent in adolescence and can have harmful consequences. An important question is whether use of these behaviors in adolescence sets the pattern for continued use into young adulthood. To examine the prevalence and tracking of dieting, unhealthy and extreme weight control behaviors, and binge eating from adolescence to young adulthood. Population-based, 10-year longitudinal study (Project EAT-III: Eating Among Teens and Young Adults, 1999-2010). The study population included 2,287 young adults (55% girls, 52% nonwhite). The sample included a younger group (mean age 12.8±0.7 years at baseline and 23.2±1.0 years at follow-up) and an older group (mean age 15.9±0.8 at baseline and 26.2±0.9 years at follow-up). Longitudinal trends in prevalence of behaviors were tested using generalized estimating equations. Tracking of behaviors were estimated using the relative risk of behaviors at follow-up given presence at baseline. In general, the prevalence of dieting and disordered eating was high and remained constant, or increased, from adolescence to young adulthood. Furthermore, behaviors tended to track within individuals and, in general, participants who engaged in dieting and disordered eating behaviors during adolescence were at increased risk for these behaviors 10 years later. Tracking was particularly consistent for the older girls and boys transitioning from middle adolescence to middle young adulthood. Study findings indicate that disordered eating behaviors are not just an adolescent problem, but continue to be prevalent among young adults. The tracking of dieting and disordered eating within individuals suggests that early use is likely to set the stage for ongoing use. Findings suggest a need for both early prevention efforts before the onset of harmful behavioral patterns as well as ongoing prevention and treatment interventions to address the high prevalence of disordered eating throughout adolescence and young adulthood.

              The changing demographic profile of eating disorder behaviors in the community

              Background The perception that eating disorders occur predominantly in young white upper-class women has been challenged. This study examined temporal differences to the demographic correlates of eating disorder behaviors over a 10-year period. Methods Data from cross-sectional general population surveys in 1998 (n = 3010) and 2008 (n = 3034) were collected on demographics (sex, age, income, residency), current eating disorder behaviors (binge eating, extreme dieting, purging), and health-related quality of life (SF-36). Results Below-median annual household income was associated with increased prevalence rates from 1998 to 2008 in binge eating, extreme dieting, and purging. Male sex was associated with increased prevalence rates in extreme dieting and purging. Age over 45 years was associated with increased prevalence rates in purging. In 2008 versus 1998, binge eating was associated with greater mental health-related quality of life impairment in males but not females; and greater physical health-related quality of life impairment in regional but not metropolitan areas. Extreme dieting was also associated with greater physical health-related quality of life impairment in 2008 versus 1998 in the lower but not the higher socioeconomic sector. Conclusions Findings suggest the ‘democratization’ of disordered eating, with greatest levels of associated impairment being within marginalized demographic sectors. Implications include the need for broader intervention programs and recruitment of demographically representative samples in eating disorder research.
