ABSTRACT
BACKGROUND: Adults with type 2 diabetes mellitus and comorbid depression face complex disease management. Salud y Vida, a diabetes management intervention for Mexican Americans in the Rio Grande Valley of Texas, may mitigate depression through social support and community-clinic referrals.
METHODS: In a cohort study, 292 Salud y Vida participants completed the patient health questionnaire (PHQ-9) at baseline, month 6, and month 12. A PHQ-9 score of ≥5 indicated mild depression and activated a mental health referral. Using SAS 9.4 with significance set at <.05, we conducted multivariable longitudinal negative binomial regression to assess changes in depression level.
RESULTS: The proportion of participants with a PHQ-9 ≥5 decreased from 36% at baseline to 18% in month 6 (adjusted risk ratio = 0.51, 95% CI = 0.41-0.62; P < .001). Among those with clinical depression at baseline (n = 121), mean PHQ-9 scores dropped 45% by month 6 (9.60-5.28; adjusted rate ratio = 0.55; 95% CI = 0.47, 0.65, P < .001) and an additional 22% by month 12 (5.28-4.10; adjusted rate ratio = 0.78; 95% CI = 0.66, 0.91; P < .002).
CONCLUSION: Salud y Vida participation is correlated with significant depression symptom improvements in Mexican American adults with diabetes and comorbid depression, demonstrating that chronic care management interventions can address multiple chronic conditions.
