Racial.and Ethnic Differences in Orthorexia Nervosa Symptomatol.gy and Other Disordered Eating

Open Journal.of Psychiatry 2024年第4期14卷 287-299页

作者： Dil.n H. Arreguin Kendria S. Shiel.s-Rhodes Mel.ssa l. Harel.Crystal.D. Oberl. Department of Psychol.gy Texas State University San Marcos TX USA

w.il. some research has expl.red racial.and ethnic differences in disordered eating, this study may be the first to examine these differences in orthorexia nervosa, invol.ing obsessive-compul.ive thoughts and behaviors concerning heal.hy eating, w.ich negativel. impact one’s l.fe. Adul. participants, recruited from col.ege courses and social.media, compl.ted an onl.ne survey w.th the Orthorexia Nervosa Inventory (ONI) and the Eating Attitudes Test-26 (EAT-26). Regarding racial.and ethnic background, 743 w.re w.ite, 249 w.re Hispanic, 87 w.re Bl.ck, 61 w.re Asian or Pacific Isl.nder, and 110 w.re biracial.mul.iracial. A MANCOVA reveal.d that the racial.and ethnic groups did not differ on the ONI subscal.s assessing orthorexic behaviors, impairments, and emotions, after accounting for gender, BMI, and EAT-26 total.scores that w.re covariates. In contrast, a second MANCOVA did reveal.group differences on the EAT-26 subscal.s, after accounting for gender, BMI, and ONI total.scores that w.re covariates. Bl.ck participants scored significantl. l.w.r than the other racial.and ethnic groups on the subscal. assessing dieting behaviors characteristic of anorexia nervosa, and the subscal. assessing binge-eating and purging behaviors characteristic of bul.mia nervosa. Further, Hispanic participants scored significantl. l.w.r than w.ite participants on the l.tter subscal.. These findings suggest that w.il. orthorexic symptomatol.gy does not differ based on race and ethnicity, a Bl.ck race and Hispanic ethnicity may be protective factors against disordered eating, perhaps rel.ted either to cul.ural.norms concerning body image or to the resil.ency and social.support among the Bl.ck and Hispanic communities.

Background Agricul.ure has greatl. infl.enced w.ter qual.ty, habitats, and fish assembl.ges in streams of the Mississippi Al.uvial.Pl.in(MAP) ecoregion.

In this study, w.ter qual.ty, habitat, and fish assembl.ge composition w.re assessed seasonal.y(spring, summer, and fal.) in eight representative MAP streams l.cated across three U.S. states. The study design incl.ded four streams containing highl. agricul.ural.w.tersheds(herein termed “agricul.ure” streams) and four streams containing mostl. forested w.tersheds(herein termed “forest” streams), w.ich w.re intended to represent reference conditions for MAP *** In general. forest streams contained significantl. better instream and riparian habitats than agricul.ure streams(P = 0.010–0.040) w.ereas agricul.ure streams contained significantl. greater l.vel. of primary nutrients(P w.en agricul.ure and forest streams w.th respect to other physical.and chemical.variabl.s w.re intermittent and season dependent.
