ABSTRACT: Objective: Aspiration pneumonia is thought to be caused by a decline in respiratory
and swallowing function. We aimed to clarify whether the pectoralis
major muscle and the rectus abdominis muscles are prognostic factors for aspiration
pneumonia and to investigate the relationships between these muscles
and nutritional status, swallowing function and sarcopenia, Methods: Medical records of 139 Japanese patients hospitalized for aspiration pneumonia
between December 2010 and December 2014 were reviewed retrospectively.
The volume and thickness of the pectoralis major muscle, the crosssectional
area and thickness of the rectus abdominis muscles, and cross-sectional
area of the psoas major muscle were measured using computed tomography.
Swallowing function, nutritional status, activities of daily living, and
prognosis also were evaluated. Results: The volume [Median: (left) 4713.2

muscle may be an independent factor in the prognosis of elderly patients with aspiration pneumonia as a primary disease.
