Abstract
Negative self-perceptions of aging (SPA) have been shown to result in lower levels of preventive behavior, health, and longevity. This study focuses on the understudied SPA effects on healthy eating across the life span. Moreover, it aims to provide longitudinal evidence of the psychological mechanisms behind this relationship.\nWe investigated whether SPA (T1) can predict changes in eating behavior (T3) over 1 year in 1,321 participants (T1), aged 18-92 years. The explanatory role of social-cognitive processes (T1, T2) was tested via a two-step mediation analysis with multigroup modeling for different age and education levels.\nBaseline positive SPA predicted more healthy eating at T3 (b = 0.68, SE = 0.24, p = .01), controlling for baseline eating (T1), age, education, gender, BMI, and illnesses. Self-efficacy (T1) and intention to eat healthily (T2) serially mediated this effect, indirect effect: b = 0.04, p = .02, 95% CI (0.02, 0.08). SPA had stronger effects in older and less educated participants.\nThis study provides important insights into the mechanisms behind positive SPA fueling successful health behavior change dynamics. Fostering more positive SPA through interventions might be especially important for vulnerable groups. Addressing SPA already in younger ages might help establish health-promoting life-span dynamics.\nObjectives\nMethod\nResults\nDiscussion
