The Association of Diet and Lifestyle Factors With Quality of Life and Self-Rated Health in Older Adults: The Loma Linda Longevity Study.

ABSTRACT: Introduction: Subjective health predicts mortality in older adults. We examined associations of vegetarian diet, adherence duration, and a Healthy Lifestyle Index with quality of life (QoL) and self-rated health (SRH) in adults ≥75 years. Methods: We analyzed cross-sectional data from 421 Loma Linda Longevity Study participants using ordinal logistic regression. Three hierarchical models were estimated: M1 (diet + sociodemographic covariates), M2 (M1 + diet duration + Healthy Lifestyle Index), and M3 (final fully adjusted model: M2 + BMI + multimorbidity). Moderation by adherence duration (<10 vs ≥ 10 years) was tested via interaction and stratified analyses. Results: The Healthy Lifestyle Index showed strong dose-response (highest vs lowest quartile: QoL aOR = 7.24, 9
