Concerns about aging and a drive for thinness: a factor in the biopsychosocial model of eating disorders?

Examine the association between concerns about aging and a drive for thinness.

Two groups were studied: (1) randomly selected nonclinical subjects (77 men, M +/- SD age: 44.4 +/- 18.3 years; 140 women, M +/- SD age: 41.9 +/- 15.3 years) from Ann Arbor, Michigan (replication of an earlier shopping mall-based survey); and (2) women (N = 54) who were concerned about their aging appearance (18 women with mild to moderate skin aging, M +/- SD age: 41 +/- 4 years; 36 women with moderate to severe skin aging, M +/- SD age: 62 +/- 6 years) and had volunteered for 24-week, prospective, controlled studies evaluating the efficacy of topical retinoic acid versus placebo for the treatment of aging skin. All subjects rated their aging-related concerns on previously developed scales, and completed the Drive for Thinness (DT) and Body Dissatisfaction (BD) subscales of the Eating Disorder Inventory (EDI).

In the random community survey there was a direct correlation between both concerns about the effect of aging on the appearance (men: r = .28, p < .05; women: r = .32, p < .01) and concerns about the cutaneous stigmata of aging (men: r = .38, p < .01; women: r = .28, p < .01) and DT (EDI). In the aging skin study both DT (EDI) and BD (EDI) were lower (p < .01) at 24 weeks posttherapy, in the retinoic acid (n = 32) but not the placebo (n = 22) group.

Concerns about an aging appearance can be associated with a drive for thinness and excessive dieting, factors that are important in the development of eating disorders.
