Study Details

Study Description

Brief Summary

This proposed study will test the following hypothesis: Treating depression in Hispanics and African Americans with diabetes will improve their HbA1c and quality of life while on intervention and six months after intervention.

Condition or Disease Intervention/Treatment Phase
Phase 4

Detailed Description

The medication to be used will be sertraline (Zoloft). Sertraline (Zoloft)has been proven in clinical trials to be an effective and well tolerated prescription medication that improves the quality and enjoyment of life for adults suffering from depression . Sertraline is an antidepressant and a member of the family of medications known as selective serotonin reuptake inhibitors (SSRIs). It has excellent tolerability and minimal drug-drug intereactions.

The hypothesis will be tested by the following specific aims:
  1. To determine if treating mild to moderate depression with sertraline (Zoloft) in patients with diabetes improves HbA1c.

  2. To determine if treating mild to moderate depression with sertraline (Zoloft) in patients with diabetes improves quality of life.

If our hypothesis proves correct and this treatment of depression is efficient and easy in a county hospital population of African Americans and Hispanics, researchers can move forward in finding fast and efficient means of diagnosing depression in vulnerable populations, including low-literate patients. This study is critical in that it stands to improve the HBA1c (and other metabolic parameters) and quality of life of our underserved minority community, which sadly suffers from a higher rate of almost every disease, including diabetes. Treating mild to moderate depression in a county hospital population of African Americans and Hispanics may improve quality of life and reduce/prevent complications and early death. Secondary outcomes include reduced hospitalizations, fewer missed appointments, and improved adherence to medication.

  • Outcome Measures

    Primary Outcome Measures

    1. HbA1C (%) [Month 0 and month 6]

      Change in HbA1C (%) at month 0 and month 6

    Secondary Outcome Measures

    1. Quality of Life [Month 0 and month 6]

      Quality of life (QOL) was assed at baseline and at month 6 using validated instrument Diabetes-39 Quality of Life Questionnaire. It consists of 39-item questionnaire designed to help us learn more about what affects the quality of life of people with diabetes in five dimensions of patients' lives: Diabetes Control, Anxiety and Worry, Social Burden, Sexual Functioning and Energy and Mobility. The Diabetes-39 questionnaire uses a Not Affected At All -Extremely Affected point scale score ranging from 1-7. Raw scale scores were transformed to a 0-100 scale using a linear transformation. Higher values represent a worse outcome. Overall rating of Quality-of-Life was assessed using a Lowest quality-Highest quality scale ranging from 1-7. Higher values represent an increase or improvement in overall QOL. Pattern of Diabetes Severity was measured with a Not Severe at all-Extremely Severe scale ranging from 1-7. Higher values represent increase in diabetes severity.

    Eligibility Criteria

    Criteria

    Ages Eligible for Study:
    21 Years and Older
    Sexes Eligible for Study:
    All
    Accepts Healthy Volunteers:
    No
    Inclusion Criteria:
    • All patients (men, women) who are African American or Hispanic over the age of 21 who have been diagnosed with type 2 diabetes and have a HbA1c of greater than 8.0%.
