The Live Well Be Well Study: A Community-BasedTranslational Lifestyle Program to Lower Diabetes Risk Factors in EthnicMinority and Lower–Socioeconomic Status Adults

摘要

Objectives. We evaluated a community-based, translational lifestyle program to reduce diabetes risk in lower–socioeconomic status (SES) and ethnic minority adults.Methods. Through an academic–public health department partnership, community-dwelling adults at risk for diabetes were randomly assigned to individualized lifestyle counseling delivered primarily via telephone by health department counselors or a wait-list control group. Primary outcomes (6 and 12 months) were fasting glucose level, triglycerides, high- and low-density lipoprotein cholesterol, weight, waist circumference, and systolic blood pressure. Secondary outcomes included diet, physical activity, and health-related quality of life.Results. Of the 230 participants, study retention was 92%. The 6-month group differences for weight and triglycerides were significant. The intervention group lost 2 pounds more than did the control group (P = .03) and had decreased triglyceride levels (difference in change, 23 mg/dL; P = .02). At 6 months, the intervention group consumed 7.7 fewer grams per day of fat (P = .05) and more fruits and vegetables(P = .02) than did controlparticipants.Conclusions. Despite challenges designing effectivetranslational interventions for lower-SES and minority communities, this programmodestly improved some diabetes risk factors. Thus, individualized,telephone-based models may be a promising alternative to group-basedinterventions.
