Prevalence of Orthorexic Tendencies and Their Correlates Among Lebanese Patients with Cancer.

Abstract

Individuals with cancer face daily challenges regarding diet and healthy lifestyle behaviors that may lead them to better health. This quest for improved health can be exaggerated in unhealthy ways if it is not approached with moderation as occurs with a condition called orthorexia nervosa (ON). Our aim in this study was to determine the prevalence of ON tendencies and their behavioral correlates among Lebanese adults with cancer. This was a monocentric cross-sectional study, conducted between December 2021 and February 2022, involving 366 patients. We collected data via telephone and recorded answers online on a Google form. We used the Düsseldorf Orthorexia Scale (DOS) to assess orthorexic behaviors, and we checked for behavioral correlates of orthorexia through a linear regression model using the DOS score as the dependent variable. On the DOS scale, we found that 9% of these participants showed possible ON tendencies, whereas 22.2% had definite ON tendencies. Factors associated with having more ON tendencies were (a) receipt of hormonotherapy, (b) being female and (c) having breast cancer. Having prostate cancer was significantly associated with fewer ON tendencies. Our results should help improve the management of patients with cancer through programs to increase patient awareness and education.
