Brief Summary:
The Lawrence Latino Diabetes Prevention Project (LLDPP) is a community-based translational research study which aims to reduce the risk of diabetes among Latinos who have a >30% probability of developing diabetes in the next 7.5 years per a predictive equation. The project was conducted in Lawrence, Massachusetts; a predominantly Caribbean-origin urban Latino community. Individuals were identified primarily from a community health center's patient panel, screened for study eligibility, randomized to either a usual care or a lifestyle intervention condition, and followed for one year.

Condition or disease Intervention/treatment Phase
Metabolic Syndrome Behavioral: lifestyle intervention Not Applicable

Detailed Description:
The group format of the intervention included 13 group sessions complemented by 3 individual home contacts over one year and was implemented by individuals from the community with training and supervision by a clinical research nutritionist and a behavioral psychologist. Study measures included demographics, Stern predictive equation components (age, gender, ethnicity, fasting glucose, systolic blood pressure, HDL-cholesterol, body mass index, and family history of diabetes), glycosylated hemoglobin, dietary intake, physical activity, depressive symptoms, social support, and quality of life. Body weight was measured at baseline, 6-months, and one-year; all other measures were assessed at baseline and one-year. All surveys were orally administered in Spanish.

Intervention Details:
  • Behavioral: lifestyle intervention
    A group-based intervention including 13 group sessions complemented by three individual home visits was developed using principles of social learning theory and patient-centered counseling. The intervention was intended to increase awareness of diabetes prevention strategies, foster positive diabetes prevention attitudes (i.e., self-efficacy) and promote healthy lifestyle behaviors in the target Latino population using literacy-sensitive and culturally-tailored strategies and materials.

Primary Outcome Measures :
  1. Weight loss. [ Time Frame: 1 year ]
  2. HgbA1c [ Time Frame: 1 year ]

Secondary Outcome Measures :
  1. Change in fasting blood sugar. [ Time Frame: 1 year ]
  2. Changes in LDL- and HDL-cholesterol. [ Time Frame: 1 year ]
  3. Change in blood pressure. [ Time Frame: 1 year ]
  4. Change in depression. [ Time Frame: 1 year ]
  5. Change in quality of life. [ Time Frame: 1 year ]
