Data were obtained through a logistic regression analysis. aMED was categorized with the use of the fourth and fifth quintiles (higher adherence = reference) compared with the other 3 quintiles. Median values for all scores were considered for the logistic regression analysis except for CES-D, for which 16 was considered to be the cutoff of clinical depression. The fully adjusted model included the following as covariates: age, sex, race, BMI (in kg/m2), education, smoking status, annual income, Charlson comorbidity index, use of analgesic drugs, and total energy intake. P < 0.05 was considered significant after adjusting for all covariates in the fully adjusted model. aMED, adherence to Mediterranean diet; CES-D, Center for Epidemiologic Studies Depression Scale; MCS, mental health composite scale; PCS, physical composite scale; SF-12, 12-Item Short-Form Health Survey; WOMAC, Western Ontario and McMaster Universities Arthritis Index.
