  Purpose

This is a randomized comparative effectiveness trial to evaluate the health and economic effects of a community-based intensive lifestyle intervention for adult primary care patients with elevated body mass index and dysglycemia (either type 2 diabetes or pre-diabetes). The study will use qualitative and quantitative methods to assess reach, effectiveness, costs, adoption, implementation, and maintenance of a clinical-community partnership to offer intensive lifestyle intervention resources to eligible adult primary care patients.

Primary Outcome Measures:
  • % Change in Body Weight [ Time Frame: Baseline to 12 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Incremental Costs [ Time Frame: 6, 12, and 24 months ] [ Designated as safety issue: No ]
    The study will capture direct medical, direct non-medical, and indirect costs from individual participants. Mean changes in these costs will be compared across randomized study arms.

  • Changes in Health State Utility [ Time Frame: Baseline to 6,12, and 24 months ] [ Designated as safety issue: No ]
    The study collects individual participant survey data that will include the Medical Outcomes Study Short Form-12 health-related quality of life questionnaire. Responses from the questionnaire are used to construct a validated numerical score that expresses global health-related quality of life across a range of 0 (death) to 1 (perfect health). Changes in this indicator will be evaluated.

  • % Change in Body Weight [ Time Frame: Baseline to 6 and 24 months ] [ Designated as safety issue: No ]
  • % Change in Blood Total Cholesterol [ Time Frame: Baseline to 6, 12, and 24 months ] [ Designated as safety issue: No ]
  • % Change in A1c [ Time Frame: Baseline to 6, 12, and 24 months ] [ Designated as safety issue: No ]
  • % Change in Blood Pressure [ Time Frame: Baseline to 6, 12, and 24 months ] [ Designated as safety issue: No ]
  • % Change in Dietary Composition [ Time Frame: Baseline to 6, 12, and 24 months ] [ Designated as safety issue: No ]
  • % Change in Physical Activity [ Time Frame: Baseline to 6, 12, and 24 months ] [ Designated as safety issue: No ]

Arms Assigned Interventions
Active Comparator: Standard Lifestyle Advice
Primary care-based identification of pre-diabetes and/or type 2 diabetes with standard clinical education (offered by participant's usual primary care providers) and brief lifestyle advice (delivered by a study Research Assistant).
Behavioral: Standard Lifestyle Advice
Standard clinical education is offered routinely by the participant's usual primary care team. Primary care teams receive educational outreach visits and are provided with clinical recommendations for lifestyle and cardiovascular risk factor management. Brief lifestyle advice is delivered by a study Research Assistant at baseline, 6, 12, and 24 months.
Other Name: Brief Lifestyle Advice
Experimental: Advice PLUS Lifestyle Intervention
Primary care-based identification of pre-diabetes and/or type 2 diabetes with standard clinical education (offered by participant's usual primary care providers) and brief lifestyle advice (delivered by a study Research Assistant) PLUS access to an intensive group-based lifestyle intervention offered in a community setting.
Behavioral: Standard Lifestyle Advice
Standard clinical education is offered routinely by the participant's usual primary care team. Primary care teams receive educational outreach visits and are provided with clinical recommendations for lifestyle and cardiovascular risk factor management. Brief lifestyle advice is delivered by a study Research Assistant at baseline, 6, 12, and 24 months.
Other Name: Brief Lifestyle Advice
Behavioral: Advice PLUS Lifestyle Intervention
Standard clinical education offered routinely by the participant's usual primary care team. Primary care teams receive educational outreach visits for lifestyle and cardiovascular risk factor management. Brief lifestyle advice delivered by a study research assistant at baseline, 6, 12, and 24 months. AND, participant offered free of charge access to an intensive lifestyle intervention offered in a community setting. Lifestyle interventions are delivered in community settings by lay instructors from community organizations who are centrally trained by the study team.
