Despite the developmental and clinical importance of body image during the pre-adolescent and adolescent years, there remains a dearth of information on the body image experiences of immigrant children and adolescents. This thesis represents a purposeful attempt to examine body image experiences among immigrant and ethnic minority children and adolescents in Canada and the United States (US). Specifically, the thesis integrates multiple methods (scoping reviews, qualitative interpretive description, quantitative multi-level modeling) and samples (clinical and population-based samples) to systematically contribute to the academic literature focusing on body image experiences among immigrant and ethnic minority children and adolescents in Canada and the US. Consisting of four conceptually related studies, this thesis makes the following methodological and conceptual contributions to epidemiological and clinical research and practice. First, the results from all four studies point to the need to develop standardized approaches for identifying and classifying immigrant and ethnic-minority children and adolescents. This will substantially increase the field’s ability to systematically characterize the nature and magnitude of body image dissatisfaction, body image distortion, and their associated outcomes among immigrant and ethnic minority children and adolescents. In addition, this systematic classification has the potential to inform the development or adaptation of universal and targeted preventative intervention strategies. Second, Study’s 1 and 2 demonstrate a clear need to further examine the constructs and experiences of acculturation and acculturative stress in relation to the body image experiences of immigrant and ethnic minority children and adolescents. The literature is unclear with respect to whether or not immigrant adolescents’ adoption of the values, behaviours and ideals of the Canadian or US culture increases their risk for body image concerns. On the other hand, we are also unclear as to whether or not immigrant adolescents’ retaining of the values, behaviours and ideals of their culture of origin may offer protection from poor body image experiences. Similarly, we are unclear about whether—and to what extent—stress as a result of adolescents’ acculturative experiences (i.e. acculturative stress) influence the onset or pervasiveness of body image concerns. Greater understanding about these constructs and processes and the extent to which they are implicated in the body image experiences among immigrant children and adolescents has the potential to inform culturally competent and targeted intervention approaches. Results from Study 3 indicate that immigrant adolescents have body image and appearance-related concerns that extend beyond what has typically been found among non-immigrant adolescents. More specifically, immigrant adolescents are concerned about the appearance of their skin (texture, complexion), their hair, their teeth, as well as other bodily features. It would be prudent for future researchers and clinicians to consider this information in relation to measuring, classifying and addressing body image dissatisfaction among immigrant adolescents. Finally, Study 4 demonstrates that females and first generation immigrants with body image dissatisfaction are at significantly elevated risk for body image distortion. This suggests that the assessment and intervention for body image dissatisfaction—particularly among females—soon after the migratory experience may play an important role in reducing body image distortion experiences. Taken together, the findings of this thesis strengthen the body image field by demonstrating that there are several unique aspects about being an immigrant that can influence adolescents’ body image experiences; and therefore, should be considered from a conceptual and methodological standpoint in future research and implementation of body image interventions. / Dissertation / Doctor of Philosophy (PhD) / Body image dissatisfaction and body image distortion have been linked to serious psychological outcomes, including depression and eating disorders. Yet, we know very little about the nature of these experiences among immigrant and ethnic minority children and adolescents. This thesis uses qualitative and quantitative methods, as well as general population and clinical samples to investigate body image dissatisfaction and body image distortion among immigrant and ethnic minority children and adolescents in Canada and the United States. Results provide important information that can inform the development of preventative interventions targeting body image dissatisfaction and body image distortion among immigrant and non-immigrant children and adolescents.

The research of the researching problems was grounded in via questionnaire (totally 270 questionnaires, 30 on each type of the school) which was conducted at Special Secondary School, Secondary Medical School and Grammar School with students of 1., 2., 3. graded in České Budějovice. Hypothesis assumed a heightened risk of arising disorder of food intake, bigger bias in their bodies and a heightened anxiety at the same time at Grammar School students which was also confirmed by the research. The conclusion includes a recommendation of precaution for parents, pedagogues and educators. It could provide them with sufficient amount of information about possible risks and curative procedures. It would be possilbe to emerge arising disorder of food ingake to obviate at all, thanks to.
