RESUMO
Measures of body dissatisfaction have not been validated for Mexican American (MA) women, who evaluate their bodies differently than Caucasian women. In this study, the psychometric properties of the EDI-III, Body Dissatisfaction Subscale (BDS) were examined in a sample of college-enrolled MA women using the Rasch Rating Scale Model. Criterion validity was also addressed. BDS evidenced good item fit, person and item reliability, once poorly correlated items were removed. Two qualitatively distinct dimensions of body dissatisfaction were identified: (1) overall body shape and stomach, and (2) the lower body. Validity of the scales was supported. Results suggest: MA women's satisfaction with overall body shape is not synonymous with attitudes toward their lower body.

A prevailing theory within eating disorder literature is that the process of acculturation and the strength of ethnic identity are key determinants of disordered eating and related health risk behaviors for Latinas. In this paper, we describe a longitudinal study to test the theoretical proposition that the configuration of personal identities buffers the effects of acculturation on a triad of modifiable risk behaviors (disordered eating, alcohol use and tobacco use) in college-enrolled Mexican American (MA) women. Using the self-schema model to conceptualize personal identities, we review the causal pathways linking self-schema properties to risk behaviors and describe the longitudinal design and measures used to test the hypothesized relationships. We discuss the causal role of the self-concept in the development of the risk behavior patterns among young Latinas, and the association between socio-cultural factors and properties of the self-concept. We describe our longitudinal study design that enables us to examine the pattern of association among the risk behaviors, and the appropriateness of measures that operationalize the theoretical concepts in the study.
RESUMO
Recent research has shown that disordered eating behaviors are as prevalent in heterogenous samples of Latinas living in the U.S. as in non-Hispanic white women, yet less is known about the prevalence in women of Mexican origin. The primary purpose of this study is to report the prevalence and associations among DE behaviors and health risk of alcohol, tobacco use and obesity in a sample of N = 472 young adult college enrolled Mexican American (MA) women living in the United States. This report focuses on baseline data from a 12-month repeated measures longitudinal study. Ecological momentary assessment (EMA) was used to capture the prevalence of disordered eating and health risk behaviors in the context of everyday activities. Disordered eating behaviors including purging, binge eating, fasting and exercise were reported by approximately 15% of the sample. Food/calorie restricting, was the most prevalent behavior reported by 48% of the sample and along with binge eating was a positive predictor of BMI. Fasting was the only disordered eating behavior associated with tobacco use. These findings suggest that subclinical levels of DE behaviors are prevalent in a community sample of women of Mexican origin and are associated with health risks of tobacco use and higher BMI. Early identification of DE behaviors and community-based interventions targeting MA women may help reduce disparities associated with overweight and obesity in this population.

Eating disorder behaviors are prevalent in Latina populations. This study tested Schwartz's (2006) theoretical view that a broad array of personal identities serves as an internal resource during acculturation and prevents internalization of dysfunctional weight related beliefs. Sixty-six Mexican American women completed measures of personal identities, fat self-definition, eating disorder symptoms and acculturation. Results show that few positive and many negative personal identities predict higher eating disorder scores and effects are mediated through the fat self-definition. Characteristics of personal identities may influence internalization of cultural values related to weight. Interventions focused on overall identity may prevent eating disorders in Latinas.
