Demographic predictors of body image satisfaction: The U.S. Body Project I.

We examined how gender, body mass, race, age, and sexual orientation were linked to appearance evaluation, overweight preoccupation, and body image-related quality of life among 11,620 adults recruited via Mechanical Turk. Men were less likely than women to report low appearance evaluation, high overweight preoccupation, negative effects of body image on their quality of life, being on a weight-loss diet, and trying to lose weight with crash diets/fasting. Racial differences were generally small, but greater appearance evaluation was reported by Black men versus other groups and Black women versus White women. Across all measures, gay and bisexual men reported poorer body image than heterosexual men, with only small effect sizes observed for sexual orientation differences among women. Body mass, but not age, was strongly associated with body image. The prevalence of poor body image highlights the need for interventions. On the positive side, half of men and women reported high appearance evaluation. Examination of this group could identify factors promoting positive body image.

Demographic predictors of objectification theory and tripartite influence model constructs: The U.S. Body Project I.

We examined how demographic factors (gender, sexual orientation, racial group, age, body mass) were linked to measures of sociocultural appearance concerns derived from objectification theory and the tripartite influence model (McKinley & Hyde, 1996; Schaefer et al., 2015) among 11,620 adults. Men were less likely than women to report high body surveillance, thin-ideal internalization, appearance-related media pressures, and family pressures; did not differ in peer pressures; and reported greater muscle/athletic internalization. Both men and women expressed greater desire for their bodies to look "very lean" than to look "very thin". Compared to gay men, heterosexual men reported lower body surveillance, thin-ideal internalization, peer pressures, and media pressures. Black women reported lower thin-ideal internalization than White, Hispanic, and Asian women, whereas Asian women reported greater family pressures. Being younger and having higher BMIs were associated with greater sociocultural appearance concerns across most measures. The variation in prevalence of sociocultural appearance concerns across these demographic groups highlights the need for interventions.
