Clinical trials

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.

Decreased testosterone levels in middle-aged men are associated with multiple metabolic, functional and psychosocial consequences. Early identification of modifiable factors associated with reduced testosterone levels may facilitate the early identification of men at increased risk of testosterone deficiency and support preventive healthcare strategies. This population-based cross-sectional observational study aims to investigate anthropometric, functional and lifestyle-related factors associated with serum total testosterone levels in middle-aged men. Approximately 600 men aged 35-59 years residing in the Andijan region of Uzbekistan will be recruited. Participants will undergo comprehensive assessment including anthropometric measurements, functional performance tests, standardised questionnaires and laboratory determination of serum total testosterone concentrations. Anthropometric variables will include body mass index, waist circumference, hip circumference, waist-to-hip ratio and waist-to-height ratio. Functional status will be assessed using hand-grip strength, the five-times chair-stand test and the 4-m walk test. Lifestyle-related factors will be assessed using standardised and study-specific questionnaires. Physical activity will be assessed using the International Physical Activity Questionnaire-Short Form (IPAQ-SF), while dietary habits, sleep characteristics, smoking status, alcohol consumption and psychosocial characteristics will be assessed using a structured study questionnaire. The study aims to identify factors associated with serum total testosterone levels and to develop a predictive model for the early identification of men at increased risk of testosterone deficiency.
