Background: Swallowing difficulties in the oral cavity or pharynx (i.e., oropharyngeal dysphagia) are a common problem in the aging population, which may result in severe consequences, such as malnutrition, aspiration pneumonia, and mortality. Identifying oropharyngeal dysphagia and its associated factors is essential for establishing better healthcare policies in nursing homes. In this study, we aimed to describe the oropharyngeal dysphagia prevalence among nursing home residents, and to investigate the association between dysphagia and potentially related factors in a large survey of nursing home residents in Sweden, including individuals with various degrees of cognitive impairment. A secondary aim was to compare findings between years on oropharyngeal dysphagia and its associated factors. Methods: This study is based on two cross-sectional surveys performed in 2007 and 2013, including 4,995 individuals living in nursing homes in the Region of Västerbotten, Sweden. Data were collected from caregivers’ reports regarding swallowing ability, nutritional status, chewing ability, and other baseline characteristics, such as cognitive function and activity of daily living (ADL). Data were analyzed using logistic regression models to calculate the odds of the association between oropharyngeal dysphagia and associated factors. Results: Oropharyngeal dysphagia was reported in 14.9% (95% CI: 13.9–16.0) of the nursing home residents. An adjusted model revealed that oropharyngeal dysphagia was associated by severe cognitive impairment (OR: 1.56, 95% CI: 1.14–2.12) and ADL independence (OR: 0.81 95% CI: 1.82–2.66) among nursing home residents. We also identified the following as independently associated factors of dysphagia: reduced nutritional status (OR: 1.84, 95% CI: 1.49–2.27), artificial nutrition (OR: 6.33, 95% CI: 2.73–14.71), and clinical signs of aspiration (OR: 10.89, 95% CI: 8.40–14.12). Conclusions: Oropharyngeal dysphagia was reported among approximately 15% nursing home residents and was ...
