This study investigated the moderating role of religiosity in the relationship between body-mass index (BMI) and body image in Iranian women. A convenience sample of 1,000 Iranian women (Mage = 41 years) voluntarily participated in the study and responded to a set of questions that measured the constructs of religiosity and body image, as well as questions on demographic and physiological characteristics. Structural equation modeling was used to test the hypotheses. The findings showed that BMI significantly affected body dissatisfaction in women. Moreover, the results revealed that women’s religiosity not only was related to healthier body image, but also dampened the association between BMI and negative body image in a Muslim country where wearing the hijab is mandatory for women. Implications of the study are discussed with recommendations for future research. (PsycINFO Database Record (c) 2019 APA, all rights reserved)
