Although dieting and unhealthy weight control-related behaviors such as binge eating, intentional vomiting and laxative use have been extensively studied in the white population, little is known about the prevalence of these behaviors in nonwhite populations. Furthermore, no studies have examined the validity of measures of dieting and unhealthy weight control practices in nonwhite populations. Validity of these measures in nonwhite populations is important to establish in order to accurately assess the prevalence of unhealthy weight control practices in nonwhite populations. The aim of the present study is to examine the validity of measures of dieting and unhealthy weight control behaviors in a multiracial population-based sample of adolescent youth.
The specific aims are to:
conduct a school-based survey of 500 adolescent youth of predominantly nonwhite ethnic/racial groups about eating and weight control-related behaviors,
identify a subsample of 150 adolescents who represent a "high risk" group for eating problems based upon their responses to the initial survey,
identify a subsample of 150 adolescents with no significant eating problems based on their responses to the initial survey to serve as a control group,
conduct in-depth interview with the adolescents identified as "high risk" and with those selected as controls, and
determine the validity of self-reported dieting and weight control behaviors based on comparison with the results of the in-depth interviews.
This study has two specific aims:
to examine the frequency of binge eating disorder and subthreshold binge eating symptoms in subjects with type II diabetes mellitus, and
to examine the rates of other psychopathology in type II diabetics. We hypothesize that rates of binge eating disorder will be higher in obese type II diabetics than in a control group closely matched for age, sex, and weight. We also hypothesize that binge eating disorder will be more common in obese than in non-obese diabetics. We further hypothesize that rates of other forms of psychopathology will be elevated in the diabetic subjects, compared with controls.
