This dissertation investigated the relationships between malnutrition, dysphagia, tongue strength and mealtime outcomes in elderly residents of long term care (LTC) in three phases: a systematic literature review, prospective collection of data in LTC, and a tongue strengthening intervention. The primary goals were to determine: the prevalence of malnutrition and dysphagia; whether signs of dysphagia and reductions of tongue strength impacted meal consumption, and thereby contributed to malnutrition; and the feasibility of conducting a tongue strengthening intervention to improve mealtime outcomes. The systematic review (Chapter 2) revealed imprecise prevalence estimates for malnutrition and dysphagia due to varying definitions and measures across studies. Pilot data were collected (Chapter 3) to demonstrate the feasibility of collecting tongue strength, dysphagia and mealtime outcome data in this setting. Based on the success of the pilot study, a larger study was conducted with a sample comprising residents from 32 LTC homes (Chapter 4). Through this study, we found evidence of relationships between reduced swallowing pressures and dysphagia, as well as dysphagia and malnutrition. Finally, a tongue strengthening intervention was trialed in LTC, with the goal of improving mealtime outcomes (Chapter 5). The findings of this dissertation make several unique contributions to the dysphagia literature. This dissertation has established that dysphagia and malnutrition co-exist in LTC, and that the odds of malnutrition are increased in the presence of signs of dysphagia. Further, it has demonstrated that reduced swallowing pressures and longer mealtimes are closely linked to signs of dysphagia, and that suspected dysphagia increases almost four-fold in the context of reduced swallowing pressures. This research has shown that tongue strength can be improved in people living in long term care and, these data have contributed the first set of reference values for tongue strength of residents of LTC. Limitations are acknowledged and future work is suggested.
