Outcome Measures

Primary Outcomes (2)

  • Mean Weight Change Over 24 Months; Unadjusted Except for Affiliation

    Mean weight change (kg) of participants between the three study groups. Weight loss at 24 months, and all relevant study visits in between, will be compared 1) between PCMH (in clinic group visits) versus FFS (in clinic individual visits), 2) between DM (phone group visits) versus FFS (in clinic individual visits), and 3) between PCMH (in clinic group visits) versus DM (phone group visits). Unadjusted except for affiliation.

    Baseline and 6, 18 and 24 months

  • Mean Weight Change Over 24 Months; Adjusted

    Mean weight change (kg) of participants between the three study groups. Weight loss at 24 months, and all relevant study visits in between, will be compared 1) between PCMH (in clinic group visits) versus FFS (in clinic individual visits), 2) between DM (phone group visits) versus FFS (in clinic individual visits), and 3) between PCMH (in clinic group visits) versus DM (phone group visits). Adjusted for affiliation, sex, race/ethnicity, education, diabetes, cardiovascular disease, and travel time to clinic.

    Baseline and 6, 18 and 24 months

Secondary Outcomes (13)

  • Mean Percent Weight Loss Over 24 Months; Unadjusted Except for Affiliation

    Baseline and 6, 18 and 24 months

  • Mean Change in Systolic Blood Pressure; Unadjusted Except for Affiliation

    Baseline and 6, 18 and 24 months

  • Mean Change in Diastolic Blood Pressure; Unadjusted Except for Affiliation

    Baseline and 6, 18 and 24 months

  • Mean Change in Fasting Glucose; Unadjusted Except for Affiliation

    Baseline and 6 and 24 months

  • Mean Change in Fasting Cholesterol; Unadjusted Except for Affiliation

    Baseline and 6 and 24 months

  • +8 more secondary outcomes

Study Arms (3)

Fee-for-Service Model (FFS, In clinic individual visits)

ACTIVE COMPARATOR

Participants will receive individual counseling from their physician or other healthcare professional during regular clinic visits.

Behavioral: Fee-for-Service Model (FFS, In clinic individual visits)

Patient Centered Medical Home (PCMH, In clinic group visits)

ACTIVE COMPARATOR

Participants will take part in group weight-management counseling during in-person group visits; later sessions may be conducted via group telephone calls if the group prefers.

Behavioral: Patient Centered Medical Home (PCMH, In clinic group visits)

Disease Management (DM, Phone group visits)

ACTIVE COMPARATOR

Participants will take part in group weight-management counseling by telephone.

Behavioral: Disease Management (DM, Phone group visits)

Interventions

To be performed by participant's doctor or other healthcare professional in their doctor's office.

Also known as: Individual weight management counseling
Fee-for-Service Model (FFS, In clinic individual visits)

To be performed by a registered dietitian, a nurse or other healthcare professional in their local setting.

Also known as: Group weight management counseling (in-person and telephone)
Patient Centered Medical Home (PCMH, In clinic group visits)

To be performed by obesity treatment specialists with relevant graduate training and experience with weight loss counseling via telephone.

Also known as: Group weight management counseling (telephone)
Disease Management (DM, Phone group visits)
