An observational study in Hypothyroidism, sponsored by Andijan State Medical Institute. Recruiting at 1 site in Uzbekistan. Open to participants aged 18 Years to 59 Years. Per ClinicalTrials.gov, last updated 2026-08-28.
Sponsored by Andijan State Medical Institute · Observational
HYPOMORPH is a hospital-based observational cross-sectional study designed to comprehensively characterise internal-organ morphometry and musculoskeletal status in adults with previously diagnosed hypothyroidism receiving routine medical care in Andijan, Uzbekistan.
Approximately 500 adults aged 18-59 years will be included. Participants undergo standardised clinical and anthropometric assessment, ultrasonographic examination of the liver, pancreas and both kidneys, measurement of handgrip strength, and assessment of physical performance using the Five Times Sit-to-Stand Test and 4-m gait speed test. Sarcopenia risk and habitual physical activity are assessed using the SARC-F questionnaire and the International Physical Activity Questionnaire-Short Form (IPAQ-SF), respectively. Serum thyroid-stimulating hormone (TSH) and free thyroxine (FT4) concentrations are measured to characterise thyroid functional status at the time of assessment.
The study evaluates ultrasonographic morphometric characteristics of the liver, pancreas and kidneys and musculoskeletal functional characteristics, and investigates their associations with thyroid-related, anthropometric, clinical and laboratory variables. Multivariable regression analyses will be used to identify factors independently associated with organ-specific morphometric and functional outcomes.
Hypothyroidism is associated with systemic manifestations extending beyond the thyroid gland, including hepatic, renal, pancreatic and musculoskeletal alterations. Previous studies have predominantly evaluated individual organs, metabolic outcomes or isolated components of physical function. Concurrent standardised assessment of multiple-organ morphometry, anthropometry, muscle strength and physical performance within the same population remains limited, particularly in Central Asian populations.
HYPOMORPH is a hospital-based observational cross-sectional study conducted among adults aged 18-59 years with a previously established diagnosis of hypothyroidism who are receiving routine outpatient or inpatient care at participating healthcare institutions in Andijan, Uzbekistan.
The study uses an integrated assessment of internal-organ morphometry and musculoskeletal status. Internal-organ assessment includes standardised ultrasonographic evaluation of the liver, pancreas and both kidneys. Musculoskeletal assessment includes anthropometric measurements, handgrip strength and objective physical performance testing using the Five Times Sit-to-Stand Test and 4-m gait speed test. Sarcopenia risk is assessed using the SARC-F questionnaire, and habitual physical activity is assessed using the International Physical Activity Questionnaire-Short Form (IPAQ-SF).
Clinical and treatment-related characteristics, including duration of hypothyroidism and levothyroxine therapy, are recorded. Serum thyroid-stimulating hormone (TSH) and free thyroxine (FT4) concentrations are measured to characterise thyroid functional status at the time of assessment.
The study aims to characterise organ-specific morphometric and musculoskeletal features in adults with hypothyroidism and to investigate their relationships with thyroid-related, anthropometric, clinical and functional characteristics. Multivariable analyses will be used to evaluate factors independently associated with organ-specific morphometric and functional outcomes.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Adults aged 18-59 years with a previously established diagnosis of hypothyroidism who are receiving routine outpatient or inpatient care at participating healthcare institutions in Andijan, Uzbekistan. Participants undergo standardised clinical and anthropometric assessment, ultrasonographic evaluation of the liver, pancreas and both kidneys, musculoskeletal functional assessment and laboratory testing according to the study protocol.
Other: Comprehensive Morphometric and Functional Assessment
Participants undergo a standardised study assessment including clinical evaluation, anthropometric measurements, ultrasonographic examination of the liver, pancreas and both kidneys, handgrip strength measurement, the Five Times Sit-to-Stand Test, 4-m gait speed assessment, physical activity and sarcopenia screening, and laboratory measurement of serum TSH and FT4. No therapeutic intervention or modification of routine clinical management is involved.
Liver Ultrasonographic Morphometry
Ultrasonographic assessment of the liver will include predefined linear morphometric measurements obtained using standardised anatomical landmarks and measurement procedures. Measurements will be recorded in millimetres (mm). Organ-specific morphological characteristics, including liver contours, echogenicity and echostructure, will be recorded as complementary ultrasonographic characteristics.
Time frame: Baseline
Pancreatic Ultrasonographic Morphometry
Ultrasonographic assessment of the pancreas will include anteroposterior measurements of the pancreatic head, body and tail using standardised anatomical landmarks and measurement procedures. Measurements will be recorded in millimetres (mm). Pancreatic echogenicity and echostructure will be recorded as complementary ultrasonographic characteristics.
Time frame: Baseline
Renal Ultrasonographic Morphometry
Both kidneys will be assessed separately by ultrasonography. Longitudinal, transverse and anteroposterior dimensions will be measured using standardised anatomical landmarks and measurement procedures and recorded in millimetres (mm). Relevant renal parenchymal characteristics will be recorded as complementary ultrasonographic characteristics.
Time frame: Baseline
Five Times Sit-to-Stand Test
Lower-extremity physical function will be assessed using the Five Times Sit-to-Stand Test. The time required to complete five consecutive chair stands without using the arms will be recorded in seconds. Longer completion times indicate poorer physical performance.
Time frame: Baseline
4-m Gait Speed
Physical performance will be assessed using the 4-m gait speed test according to a standardised protocol. Gait speed will be calculated in metres per second (m/s), with higher values indicating faster walking speed.
Time frame: Baseline
Anthropometric Characteristics
Anthropometric assessment will include body mass index (BMI), waist circumference, hip circumference, peripheral body circumferences, waist-to-hip ratio (WHR) and waist-to-height ratio (WHtR), measured or calculated according to standardised procedures.
Time frame: Baseline
Handgrip Strength
Muscle strength will be assessed using handgrip dynamometry according to a standardised measurement protocol. Maximum handgrip strength will be recorded in kilograms (kg), with higher values indicating greater muscle strength.
Time frame: Baseline
SARC-F Score
Sarcopenia risk will be assessed using the SARC-F questionnaire. The total SARC-F score will be calculated according to the standard scoring procedure, with higher scores indicating greater risk of sarcopenia.
Time frame: Baseline
Physical Activity Assessed by IPAQ-SF
Habitual physical activity will be assessed using the International Physical Activity Questionnaire-Short Form (IPAQ-SF). Information on walking, moderate-intensity physical activity, vigorous-intensity physical activity and sedentary time will be collected, and physical activity variables will be derived according to established IPAQ scoring procedures.
