About this study

Official title: Comparison of Segmental Body Composition Characteristics in Lipedema and Obesity: A Body Mass Index-Matched Bioelectrical Impedance Analysis Study

The aim of this study is to compare the total and regional body composition characteristics of women with lipedema and women without lipedema who are matched for age and body mass index, as determined by the TANITA MC-580 segmental bioelectrical impedance analysis (BIA) device. In addition to total fat mass and fat percentage, fat mass, fat-free mass, and muscle mass measurements of the right and left legs, right and left arms, and trunk are planned to be evaluated. From these measurements, regional distribution indicators such as the proportion of lower extremity fat mass within total body fat, the leg-to-trunk fat ratio, the leg-to-arm fat ratio, and the leg muscle-to-fat ratio will be calculated. In addition, the study aims to examine the relationships between segmental body composition characteristics and disease type and stage, disease duration, pain severity, and lower extremity function in the lipedema group.

Hypothesis: The proportion of total body fat located in the lower extremities is significantly higher in women with lipedema compared to women without lipedema matched for age and body mass index.

Read the detailed description

This cross-sectional observational study aims to evaluate body composition characteristics in women with lipedema and examine their associations with clinical symptoms and functional status. Body composition will be assessed using bioelectrical impedance analysis, including body fat percentage, muscle mass, total body water, visceral fat level, and segmental body composition parameters. Anthropometric measurements and lipedema-related clinical characteristics will also be recorded. Pain severity, lower-extremity function, and health-related quality of life will be evaluated using validated patient-reported outcome measures. The findings obtained from this study are not intended to establish the diagnosis of lipedema based solely on BIA measurement; rather, they are expected to contribute to the identification of objective and measurable body composition indicators that can support existing clinical assessment. The segmental parameters and candidate distribution indices to be identified may offer research indicators that could be validated in different samples in the future. Furthermore, demonstrating the relationship between regional fat and muscle distribution and pain and lower extremity function in women with lipedema may contribute to the development of a more comprehensive approach that can be used in the evaluation and follow-up of patients.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Bioelectrical Impedance AnalysisOther

    Body composition will be assessed using bioelectrical impedance analysis. Total and segmental body composition parameters, including body fat mass, body fat percentage, muscle mass, and total body water, will be recorded.

  • Numeric Rating ScaleOther

    Also called NRS

    Pain intensity will be evaluated using the Numeric Rating Scale, ranging from 0 (no pain) to 10 (worst imaginable pain).

  • Lower Extremity Functional ScaleOther

    Also called LEFS

    Functional status will be assessed using the Lower Extremity Functional Scale. The total score ranges from 0 to 80, with higher scores indicating better lower extremity function and lower disability levels.

  • Short Form-12Other

    Also called SF-12

    Health-related quality of life will be assessed using the SF-12 questionnaire, including the Physical Component Summary (PCS-12) and Mental Component Summary (MCS-12) scores. Scores range from 0 to 100, with higher scores indicating better perceived health status and quality of life.

  • Clinical StagingOther

    Lipedema stage will be determined according to clinical examination findings and established diagnostic criteria.

What is being measured

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

  1. Ratio of the total fat mass of the two legs to total body fat mass

    The ratio will be calculated by dividing the sum of the fat mass of both legs by total body fat mass, as measured using bioelectrical impedance analysis.

    Measured: Baseline

Secondary outcomes (9)
  1. Total fat mass

    Total fat mass will be measured in kilograms using bioelectrical impedance analysis and represents the estimated total amount of fat mass in the body.

    Measured: Baseline

  2. Fat-free body mass

    Fat-free body mass will be measured in kilograms using bioelectrical impedance analysis and represents total body mass excluding fat mass.

    Measured: Baseline

  3. Total and skeletal muscle mass

    Total muscle mass and skeletal muscle mass will be measured in kilograms using bioelectrical impedance analysis and represent the estimated amounts of total muscle tissue and skeletal muscle tissue in the body, respectively.

    Measured: Baseline

  4. Total body water

    Total body water will be measured in kilograms using bioelectrical impedance analysis and represents the estimated total amount of water in the body.

    Measured: Baseline

  5. Visceral fat level

    Visceral fat level will be assessed using bioelectrical impedance analysis and reported as a device-generated rating reflecting the estimated amount of fat surrounding the internal abdominal organs.

    Measured: Baseline

  6. Leg-to-trunk fat ratio

    The leg-to-trunk fat ratio will be calculated by dividing the sum of the fat mass of both legs by trunk fat mass, as measured using bioelectrical impedance analysis.

    Measured: Baseline

  7. Leg-to-arm fat ratio

    The leg-to-arm fat ratio will be calculated by dividing the sum of the fat mass of both legs by the sum of the fat mass of both arms, as measured using bioelectrical impedance analysis.

    Measured: Baseline

  8. Leg muscle-to-fat ratio

    The leg muscle-to-fat ratio will be calculated by dividing the total muscle mass of both legs by the total fat mass of both legs, as measured using bioelectrical impedance analysis.

    Measured: Baseline

  9. Right-left extremity asymmetry

    Right-left extremity asymmetry will be assessed by calculating the absolute differences in fat mass and muscle mass between the right and left upper and lower extremities, as measured using bioelectrical impedance analysis.

    Measured: Baseline
