Summary

This study looks at how physical activity, tiredness, social support, and mental well-being are related in women with primary hypothyroidism (an underactive thyroid). Researchers will track 96 women from clinics in Asturias, Spain, using questionnaires. The goal is to understand which factors most affect activity levels, but no new treatment or medication is being tested.

Inclusion Criteria: * Have a diagnosis of primary hypothyroidism (clinical or subclinical), established by a specialist in Endocrinology or Internal Medicine based on TSH and FT4 levels. * Female. * Are aged ≥18 years at the time of inclusion. * Have stable treatment for thyroid dysfunction (levothyroxine dose or other replacement regimen without relevant modifications) for at least the previous 3 months, or a stable clinical condition if treatment is not required. * Are able to ambulate independently in the community (with or without usual assistive devices), allowing participation in light to moderate physical activity. * Are able to understand and complete the questionnaires independently. * Have provided written informed consent Exclusion Criteria: * Have a diagnosis of severe medical conditions that predominantly limit the ability to perform physical activity independently of hypothyroidism (e.g., advanced heart failure, severe chronic respiratory disease). * Have severe psychiatric disorders or significant cognitive impairment that hinder understanding of the information or reliable completion of the questionnaires. * Have undergone major surgery, severe trauma, or an acute medical condition that has substantially limited physical activity in the three months prior to assessment. * Are pregnant or in the immediate postpartum period, due to potential hormonal and functional interference with the study variables. * Are concurrently participating in a clinical trial or a structured physical exercise program.
