About this study

Official title: Rural Engagement in Primary Care for Optimizing Weight Reduction (RE-POWER)

The purpose of this study is to compare three methods for managing obesity in rural patients, to see which method will result in patients being able to attain their weight loss goal and maintain that weight loss.

Read the detailed description

Nearly 20% of the U.S. population lives in rural communities. Rural residents suffer at a higher rate from obesity and obesity-related illnesses, including diabetes, heart disease, and arthritis. Local primary care physicians are an important resource for treating obesity in rural areas because of a lack of other community resources.

This study is looking at how effective current, real-world primary care treatment models are in helping rural residents lose weight and maintain that weight loss. Physician clinics will be randomized (like picking numbers from a hat) to conduct one of the three methods. The method a participant is part of will depend on the method their physician's clinic is randomized to. The three methods involved in this study are:

  1. Individual weight-management counseling in person (in clinic individual visits)
  2. Group weight-management counseling, both in person and by telephone; the latter if preferred by the group (in clinic group visits)
  3. Group weight-management counseling by telephone (phone group visits)

Participants will be in the study about 24 months. The number of in-person clinic visits and phone calls each participant will be asked to complete depends on the method.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 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.

    Measured: Baseline and 6, 18 and 24 months

  2. 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.

    Measured: Baseline and 6, 18 and 24 months

Secondary outcomes (13)
  1. Mean Percent Weight Loss Over 24 Months; Unadjusted Except for Affiliation

    Comparison in percent weight loss from baseline 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.

    Measured: Baseline and 6, 18 and 24 months

  2. Mean Change in Systolic Blood Pressure; Unadjusted Except for Affiliation

    Mean change in systolic blood pressure will be compared across all treatment arms; unadjusted except for affiliation.

    Measured: Baseline and 6, 18 and 24 months

  3. Mean Change in Diastolic Blood Pressure; Unadjusted Except for Affiliation

    Mean change in diastolic blood pressure will be compared across all treatment arms; unadjusted except for affiliation.

    Measured: Baseline and 6, 18 and 24 months

  4. Mean Change in Fasting Glucose; Unadjusted Except for Affiliation

    Mean change in fasting glucose will be compared across all treatment arms; unadjusted except for affiliation.

    Measured: Baseline and 6 and 24 months

  5. Mean Change in Fasting Cholesterol; Unadjusted Except for Affiliation

    Mean change in fasting cholesterol will be compared across all treatment arms; unadjusted except for affiliation.

    Measured: Baseline and 6 and 24 months

  6. Mean Change in Fasting Triglycerides; Unadjusted Except for Affiliation

    Mean change in fasting triglycerides will be compared across all treatment arms; unadjusted except for affiliation.

    Measured: Baseline and 6 and 24 months

  7. Mean Change in Fasting Low Density Lipoprotein (LDL); Unadjusted Except for Affiliation

    Mean change in fasting low density lipoprotein (LDL) will be compared across all treatment arms; unadjusted except for affiliation.

    Measured: Baseline and 6 and 24 months

  8. Mean Change in Fasting High Density Lipoprotein (HDL); Unadjusted Except for Affiliation

    Mean change in fasting high density lipoprotein (HDL) will be compared across all treatment arms; unadjusted except for affiliation.

    Measured: Baseline and 6 and 24 months

  9. Mean Change in Physical Quality of Life Score, Measured by SF-12; Unadjusted Except for Affiliation

    Change in physical quality of life score, measured by SF-12. The Short Form Health Survey (SF-12) is a general quality of life measure with mental functioning and physical functioning summary scores. Each is scored from 0 to 100 with higher scores representing better functioning. Measures will be collected at baseline, 6 months and 24 months. Unadjusted Except for Affiliation.

  11. Mean Change in Total Quality of Life Score Measured by IWQOL-L; Unadjusted Except for Affiliation

    The Impact of Weight on Quality of Life-Lite (IWQOL-L) measure consists of a total score and five subscales--physical function, self-esteem, sexual life, public distress, and work. The total score ranges from 0 to 100 with higher scores indicating better quality of life. Measures will be collected at baseline, 6 months and 24 months. Unadjusted Except for Affiliation.

  13. Mean Change in Stress Measured by PSS; Unadjusted Except for Affiliation

    Mean change in stress measured using the Perceived Stress Scale (PSS). Scores range from 0 to 40. Higher numbers represent greater levels of stress. Measures will be collected at baseline, 6 months, 18 months and 24 months. Unadjusted except for affiliation.

    Measured: Baseline and 6, 18 and 24 months

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 29 Jul 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Mean Weight Change Over 24 Months; Unadjusted Except for Affiliation (time frame: Baseline and 6, 18 and 24 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02456636, which also lists 7 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
