Patients often exhibit impaired nutritional status and alterations in body composition, such as dynapenia and sarcopenia, which correlate with poor pulmonary function, reduced exercise tolerance and diminished quality of life. However, the impact of dynapenia and sarcopenia on prognosis has not been examined extensively in ILD patients.<\/jats:p><jats:p>We assessed the impact of dynapenia and sarcopenia as risk factors for mortality and their prevalence in ILD.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Prospective cohort study. ILD was classified into idiopathic pulmonary fibrosis (IPF), connective tissue disease\u2010related ILD (CTD\u2010ILD) and chronic hypersensitivity pneumonitis (CHP). Patients over 18\u2009years old with a confirmed diagnosis of ILD were included, while those with diagnoses of cancer, human immunodeficiency virus and neurological disease were excluded. Dynapenia and sarcopenia were determined according to EWGSOP2 criteria.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Ninety\u2010eight ILD patients were included; 33.66% had IPF, 47.96% had CTD\u2010ILD, and 18.37% had CHP.
