About this trial

This cross-sectional study aims to investigate the relationship between postural habits and body awareness with functional performance across different body mass index (BMI) categories in women. Participants will be categorized into four groups based on BMI (normal weight, overweight, obesity class I, and obesity class II-III). Postural habits and awareness, body awareness, and functional performance will be assessed using validated questionnaires and performance-based tests. The study also aims to explore the potential contribution of central adiposity (waist circumference) and psychological factors to these relationships. Findings are expected to provide a more comprehensive understanding of the biomechanical and perceptual factors associated with obesity.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

Female individuals aged 18-65 years

Classified into BMI categories (normal weight, overweight, obesity class I, obesity class II-III)

No obesity-related medical or surgical treatment in the last 6 months

Able to understand instructions and complete questionnaires

Disqualifiers

Neurological disorders affecting mobility (e.g., stroke, Parkinson's disease, multiple sclerosis, peripheral neuropathy)

Rheumatologic or inflammatory diseases (e.g., rheumatoid arthritis, ankylosing spondylitis)

Severe orthopedic conditions limiting mobility (e.g., advanced osteoarthritis)

Major surgery within the last 12 months affecting mobility or physical performance

Trial population

The study population will consist of women aged 18-65 years recruited from the general community. Participants will be categorized into four groups based on body mass index (BMI): normal weight, overweight, obesity class I, and obesity class II-III.

Treatments tested in this trial

  • Observational Assessment

    Other intervention

    Participants will undergo a comprehensive observational assessment including anthropometric measurements, self-reported questionnaires, and performance-based functional tests. Body mass index and waist circumference will be measured to classify participants into BMI categories. Postural habits and awareness will be evaluated using the Posture Habits and Awareness Scale (PHAS), and body awareness will be assessed the Body Awareness Questionnaire (BAQ). Functional performance will be measured using the Timed Up and Go (TUG) test and the Five Times Sit-to-Stand (5×STS) test. No therapeutic or experimental intervention will be applied.

Trial outcomes

Primary outcomes

1

Postural Habits and Awareness Level (PHAS Score)

Postural habits and awareness will be assessed using the Postural Habits and Awareness Scale (PHAS), a validated self-reported questionnaire. The total score ranges from 21 to 105, with higher scores indicating better postural habits and greater awareness. The primary outcome will be the total PHAS score and its comparison across body mass index (BMI) categories, as well as its association with functional performance.

Time frame
Baseline

Secondary outcomes

1

Body Awareness Level (BAQ Score)

Body awareness will be assessed using the Body Awareness Questionnaire (BAQ), a validated self-reported instrument measuring sensitivity to normal bodily processes. The total score ranges from 18 to 126, with higher scores indicating greater body awareness. The BAQ score will be analyzed across BMI categories and in relation to postural habits and functional performance.

Time frame
Baseline
2

Functional Mobility (Timed Up and Go Test)

Functional mobility and dynamic balance will be evaluated using the Timed Up and Go (TUG) Test. The time required to stand up from a chair, walk 3 meters, turn, return, and sit down will be recorded in seconds. Scores range from 0 to an upper limit depending on performance, with lower times indicating better functional mobility and balance.

Time frame
baseline
3

Lower Extremity Functional Strength (5 Times Sit-to-Stand Test)

Lower extremity functional strength will be assessed using the Five Times Sit-to-Stand Test (5×STS). The time required to complete five repetitions of sit-to-stand will be recorded in seconds. Scores range from 0 to an upper limit depending on performance, with lower times indicating better functional performance.

Time frame
Baseline
4

Composite Functional Performance Index

A composite functional performance index will be calculated by converting Timed Up and Go Test and Five Times Sit-to-Stand Test results into z-scores and averaging them. The index has no fixed minimum or maximum value, as it is derived from standardized scores. Higher scores indicate poorer functional performance. This index will be used to examine associations with postural habits, body awareness, and BMI categories.
