Results of logistic regression of the estimation of odds of recurrent DepSs according to the 10-y change in AHEI score are shown. To analyze the 10-y change in the AHEI score, scores of AHEI at phases 3 and 7 were categorized as high or low according to the median value of the AHEI score at phase 3 equal to 51.5 points. Model 1 was adjusted for age, ethnicity, and total energy intake at phase 3. Model 2 was adjusted as for model 1 and for SES, retirement, marital status, smoking, physical activity, hypertension, coronary artery disease, HDL cholesterol, and central obesity at phase 3. AHEI, Alternative Healthy Eating Index; DepS, depressive symptom; SES, socioeconomic status.
Four categories in 10-y change of AHEI were defined as follows: participants who maintained a high score (phase 3 and 7 scores ≥51.5 points), participants who maintained a low score over the 10-y exposure period (phase 3 and 7 scores <51.5 points), participants who improved their AHEI score (phase 3 score <51.5 points and phase 7 score ≥51.5 points), and participants who decreased their score (phase 3 score ≥51.5 points and phase 7 score <51.5 points).
