Abstract
Objective
To determine the prevalence of dysphagia among an older population and patients with stroke, head and neck cancers (HNCs) or neurodegenerative diseases (NDDs) in China, to identify the factors associated with this condition, and to explore the relationship between dysphagia and nutritional status.
Methods
This study included participants 65 years and older living in the community or in nursing homes and patients who had sustained a stroke, HNC, or NDD also recruited in hospitals from 14 provinces of China. The presence of dysphagia was determined by use of a questionnaire, water swallowing test, and/or a videofluoroscopic swallowing study. Logistic regression analysis was used to assess the possible associated risk factors. Body mass index was assessed as an indicator of malnutrition.
Results
A total of 5943 persons met the inclusion criteria and 2341 (39.4%) were identified with dysphagia, including the following: 51.14% of patients with stroke, 34.4% in HNCs, 48.3% in NDDs, and 19.2% of otherwise healthy older adults. The elderly with comorbidity (OR = 2.90, p < 0.01) and stroke patients (OR = 2.27, p < 0.01) were significantly more likely to exhibit signs of dysphagia. Dysphagic participants were at significantly greater risk of malnutrition (OR = 1.91, p < 0.01) compared to those without dysphagia.
Conclusion
Dysphagia is prevalent in China among older individuals and people who have suffered a stroke, HNCs, or NDDs. The prevalence of dysphagia increases steadily with increasing age and presence of comorbid disease. People with dysphagia are more likely to suffer from malnutrition.
