Functionality appreciation mediates the association between age and body appreciation over the lifespan in Japan

Previous findings suggest that body appreciation increases with age, whereas body dissatisfaction remains constant across the lifespan. However, the reason for this phenomenon remains unclear. In the present study, we examined the role of functionality appreciation in the association between age and body appreciation among Japanese adults. A community sample of 280 Japanese women and men (20–79 years old) completed an online cross-sectional survey with measures of functionality and body appreciation. Simple mediation analysis (PROCESS; Model 4) demonstrated that age was positively related to body appreciation and this relationship was mediated by functionality appreciation, for women, but not for men. This finding suggests that increased functionality appreciation might be a strategy for increasing body appreciation as we age, but only among women and not among men. It is possible that the adaptive strategies employed by older women could be utilized by younger women. Thus, implementing interventions focused on the enhancement of functionality appreciation might be beneficial for young women.
