Trial summary

Aging is associated with significant declines in muscle mass, strength, and physical performance, all of which lead to disability, loss of independence, and adverse clinical outcomes. Obesity exacerbates these age-related declines in function and is associated with poorer clinical outcomes and quality of life. Read more about this study

About this study

Official title: Long-term Function and Health Effects of Intentional Weight Loss in Obese Elders

Aging is associated with significant declines in muscle mass, strength, and physical performance, all of which lead to disability, loss of independence, and adverse clinical outcomes. Obesity exacerbates these age-related declines in function and is associated with poorer clinical outcomes and quality of life. Weight loss can also worsen age-related loss of muscle mass and decrease bone mineral density. The overall goals of this study are to determine if the short-term functional benefits of intentional weight loss are sustained long-term, and to examine the long-term benefits and risks of weight loss.

Read the detailed description

Obesity exacerbates age-related declines in function and is associated with poorer clinical outcomes and quality of life. Although clinical trials conducted study teams show that diet-induced weight loss interventions in obese older adults, when combined with exercise, improve body composition and physical and metabolic function in the short-term, the overall safety and long-term benefits of intentional weight loss in older adults remain controversial. Weight loss can also worsen age-related loss of muscle mass and decrease bone mineral density. Because of these concerns, health care providers are reluctant to recommend weight loss in obese older adults. The goal is to determine whether weight loss-induced improvements in body composition and physical and metabolic function observed in short-term clinical trials persist over time is critical to inform geriatric obesity treatment.

What is being measured

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

  1. 400 meter walk time

    Participants are instructed to complete the 400 m distance (on a flat indoor surface) as quickly as possible at a maintainable pace and the time to complete the walk is recorded in seconds.

    Measured: Baseline

Secondary outcomes (22)
  1. Short Physical Performance Battery score

    The Short Physical Performance Battery (SPPB) is a widely used assessment of lower extremity physical function that consists of 3 standing balance tasks held for 10 seconds each (side-by-side, tandem and semi-tandem), two 4-m walk tests to assess usual gait speed, and 5 repeated chair stands. Each of the three performance measures is assigned a score ranging from 0 (inability to do the test) to 4 (the highest level of performance) and summed to create an SPPB summary score ranging from 0 (worst) to 12 (best).

    Measured: Baseline

  2. Knee extension strength

    Maximal isokinetic knee extension strength. Maximal isokinetic knee extension strength will be measured using an isokinetic dynamometer (Biodex) at 60°/sec with the participant sitting and the hips and knee flexed at 90°. The maximum knee extensor strength of the 4 repetitions from trial 2 for the dominant leg will be will be used in analyses unless unable to test the dominant leg (i.e., knee replacement) in which case the non-dominant leg will be used.

    Measured: Baseline

  3. Total body lean mass

    Whole body lean mass will be measured by dual-energy X-ray absorptiometry (DXA).

    Measured: Baseline

  4. Appendicular lean mass

    Appendicular lean mass will be measured by DXA.

    Measured: Baseline

  5. Total body fat mass

    Whole body fat mass will be measured by DXA.

    Measured: Baseline

  6. Total hip BMD

    Bone mineral density (BMD) of the total hip will be measured by DXA.

    Measured: Baseline

  7. Femoral neck BMD

    Bone mineral density (BMD) of the femoral neck will be measured by DXA.

    Measured: Baseline

  8. Lumbar spine BMD

    Bone mineral density (BMD) of the lumbar spine (L1-L4) will be measured by DXA.

    Measured: Baseline

  9. Subcutaneous abdominal fat

    Subcutaneous abdominal fat will be measured by computed tomography (CT).

    Measured: Baseline

  10. Visceral abdominal fat

    Visceral abdominal fat will be measured by CT.

    Measured: Baseline

  11. Thigh inter-muscular adipose tissue

    Thigh inter-muscular adipose tissue will be measured by CT.

    Measured: Baseline

  12. Glucose

    Assessed via a standard clinical assay after fasting for at least 8 hours.

    Measured: Baseline

  13. Insulin

    Assessed via a standard clinical assay after fasting for at least 8 hours.

    Measured: Baseline

  14. Total cholesterol

    Assessed via a standard clinical lipid panel after fasting for at least 8 hours

    Measured: Baseline

  15. HDL cholesterol

    Assessed via a standard clinical lipid panel after fasting for at least 8 hours

    Measured: Baseline

  16. LDL cholesterol

    Assessed via a standard clinical lipid panel after fasting for at least 8 hours

    Measured: Baseline

  17. Triglycerides

    Assessed via a standard clinical lipid panel after fasting for at least 8 hours

    Measured: Baseline

  18. Systolic blood pressure

    Blood pressure will be measured in the right arm using an automated sphygmomanometer with the participant in a seated position after having rested quietly for 10-15 minutes. Participants will sit with feet flat on the floor and legs uncrossed and will be asked not to talk during the rest period or during the measurement. Systolic blood pressure will be defined as the average of three repeated measures.

    Measured: Baseline

  19. Diastolic blood pressure

    Blood pressure will be measured in the right arm using an automated sphygmomanometer with the participant in a seated position after having rested quietly for 10-15 minutes. Participants will sit with feet flat on the floor and legs uncrossed and will be asked not to talk during the rest period or during the measurement. Diastolic blood pressure will be defined as the average of three repeated measures.

    Measured: Baseline

  20. C-reactive protein

    C-reactive protein (CRP) will be determined using an automated immunoanalyzer.

    Measured: Baseline

  21. Interleukin-6

    Interleukin-6 (IL-6) will be assayed with high-sensitivity Quantikine®.

    Measured: Baseline

  22. Soluble tumor necrosis factor receptor 1

    Soluble tumor necrosis factor receptor 1 (sTNFR1) will be assayed with high-sensitivity Quantikine®.

    Measured: Baseline

Questions about this trial

What is this clinical trial studying?

An observational study of Weight Loss and Obesity, run by Wake Forest University Health Sciences at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 15 Oct 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

400 meter walk time (time frame: Baseline). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Oct 2021.
