RESUMO
PURPOSE: Acculturation, or the dual process of cultural change that takes place due to the interaction between two or more cultural identities, may contribute to the susceptibility of developing an eating disorder (ED). We conducted a systematic review exploring the relationship between acculturation-related constructs and ED pathology. METHODS: We searched the PsychINFO and Pubmed/Medline databases up to December 2022. Inclusion criteria were: (1) having a measure of acculturation or related constructs; (2) having a measure of ED symptoms; and (3) experiencing cultural change to a different culture with Western ideals. 22 articles were included in the review. Outcome data were synthesized by narrative synthesis. RESULTS: There was variability in the definition and measure of acculturation in the literature. Overall, acculturation, culture change, acculturative stress, and intergenerational conflict were associated with ED behavioral and/or cognitive symptoms. However, the nature of the specific associations differed depending on the specific acculturation constructs and ED cognitions and behaviors measured. Furthermore, cultural factors (e.g., in-group vs. out-group preferences, generational status, ethnic group, gender) impacted the relationship between acculturation and ED pathology. DISCUSSION: Overall, this review highlights the need for more precise definitions of the different domains of acculturation and a more nuanced understanding of the specific relationship between various acculturation domains and specific ED cognitions and behaviors. Most of the studies were conducted in undergraduate women and in Hispanic/Latino samples, limiting generalizability of results. LEVEL OF EVIDENCE: Level V, Opinions of respected authorities, based on descriptive studies, narrative reviews, clinical experience, or reports of expert committees.
