Racial and Ethnic Differences in Orthorexia Nervosa Symptomatology and Other Disordered Eating

引用

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

作者： Dilan H. Arreguin Kendria S. Shields-rhodes Melissa L. Harel Crystal D. Oberle Department of Psychology Texas State University San Marcos TX USA

While some research has explored racial and ethnic differences in disordered eating, this study may be the first to examine these differences in orthorexia nervosa, involving obsessive-compulsive thoughts and behaviors concerning healthy eating, which negatively impact one’s life. Adult participants, recruited from college courses and social media, completed an online survey with the Orthorexia Nervosa Inventory (ONI) and the Eating Attitudes Test-26 (EAT-26). Regarding racial and ethnic background, 743 were White, 249 were Hispanic, 87 were Black, 61 were Asian or Pacific Islander, and 110 were biracial/multiracial. A MANCOVA revealed that the racial and ethnic groups did not differ on the ONI subscales assessing orthorexic behaviors, impairments, and emotions, after accounting for gender, BMI, and EAT-26 total scores that were covariates. In contrast, a second MANCOVA did reveal group differences on the EAT-26 subscales, after accounting for gender, BMI, and ONI total scores that were covariates. Black participants scored significantly lower than the other racial and ethnic groups on the subscale assessing dieting behaviors characteristic of anorexia nervosa, and the subscale assessing binge-eating and purging behaviors characteristic of bulimia nervosa. Further, Hispanic participants scored significantly lower than White participants on the latter subscale. These findings suggest that while orthorexic symptomatology does not differ based on race and ethnicity, a Black race and Hispanic ethnicity may be protective factors against disordered eating, perhaps related either to cultural norms concerning body image or to the resiliency and social support among the Black and Hispanic communities.

THE ATHENIAN ASSEMBLY AND COUNCIL: CONTINUING PROBLEMS

The council with its limited membership and the assembly open to all citizens were important elements in the public life of Athens,and indeed of most Greek cities,and how they functioned is an important part of what we need to know in order to understand their public life;but there are still questions to which we do not have certain answers,and in this paper I focus on *** about the mechanisms is not all that we need to know;but for a city whose mechanisms were well developed,as those of Athens were,knowing about the mechanisms,and the opportunities and the limitations which they provided for the men active in politics,is an important part of what we need to know–as *** has emphasised in an article in which he justifies his approach against the criticisms of scholars who think other kinds of question more important.

A photolysis coefficient for characterizing the response of aqueous constituents to photolysis

引用

Frontiers of Environmental Science & Engineering 2016年第3期10卷 428-437页

作者： David R. HOKANSON Ke LI R. rhodes TRUSSELL Trussell Technologies Inc. Pasadena CA 91101 USA College of Engineering University of Georgia Athens GA 30602 USA

UV photolysis and UV based advanced oxidation processes （AOPs） are gaining more and more attention for drinking water treatment. Quantum yield （Ф） and molar absorption coefficient （ε） are the two critical parameters measuring the effectiveness of photolysis of a compound. The product of the two was proposed as a fundamental measure of a constituent＇s amenability to transformation by photolysis. It was shown that this product, named the photolysis coefficient, kp, can be determined using standard bench tests and captures the properties that govern a constituent＇s transformation when exposed to light. The development showed the photolysis coefficient to be equally useful for microbiological, inorganic and organic constituents. Values of kp calculated by the authors based on quantum yield and molar absorption coefficient data from the literature were summarized. Photolysis coefficients among microorganisms ranged from 8500 to more than 600000 and are far higher than for inorganic and organic compounds, which varied over a range of approximately 10 to 1000 and are much less sensitive to UV photolysis than the microorganisms.
