Overview
Brief Summary
Disparities in diagnosis and control of type 2 diabetes mellitus are most evident in African Americans (AAs) with lower socioeconomic status. Health literacy is an important predictor of adequate self-management and control of diabetes. The purpose of this pilot study was to test the feasibility and preliminary efficacy of a health literacy-enhanced diabetes intervention -Prevention through Lifestyle intervention And Numeracy (PLAN) 4 Success-Diabetes, in inner-city, low-income AAs with uncontrolled diabetes. To evaluate the feasibility, acceptability, and preliminary efficacy of the intervention, the investigators conducted a pilot study with 24-week follow-up. The investigators that participation in the PLAN 4 Success-diabetes intervention would be associated with a reduction in glucose outcomes and improvements in psychosocial variables.

Eligibility Criteria
Inclusion Criteria
- •African Americans residing in Baltimore, Maryland
- •had uncontrolled diabetes (defined as HbA1C\>7%)
Exclusion Criteria
- •Unable to give informed consent

Outcomes
Primary Outcomes
Change in Health literacy as assessed by the Newest Vital Sign
Time Frame: baseline; 12 and 24 weeks
The Newest Vital Sign consists of four items and measures numeracy. After reviewing a nutrition label, participants are asked to answer questions based on some calculation of the nutritional information (e.g., fat, sodium) presented on the label. Total possible scores range from 0 to 4, with one point assigned for each correct response.
Change in Health literacy as assessed by Literacy Assessment in Diabetes (LAD).
Time Frame: baseline; 12 and 24 weeks
The Literacy Assessment in Diabetes (LAD) has high reliability and validity indices. The items on the LAD are scored as correct/incorrect, with total possible scores ranging from 0 to 60. Higher scores indicated higher health literacy levels.
Secondary Outcomes
- Change in Diabetes knowledge measured with the validated Diabetes Knowledge Test(baseline; 12 and 24 weeks)
- Change in Diabetes self-efficacy measured with Stanford Diabetes Self-Efficacy scale(baseline; 12 and 24 weeks)
