RESUMO
OBJECTIVES: To assess the prevalence of (risk of) undernutrition in Dutch elder Parkinson's disease patients as well as it's risk factors. DESIGN: Observational cross-sectional study. SETTING: An outpatient clinic at the department Neurology of Medical Centre Leeuwarden, a large teaching hospital. PARTICIPANTS: 102 outpatients with Parkinson's disease aged 65 years and older were recruited. MEASUREMENTS: Data regarding various aspects of undernutrition including socio-demographic aspect, disease characterisitics, nutritional status, appetite and overall-physical and psychological functioning were collected. RESULTS: Undernutrition was diagnosed in 2.0% and 20.5% of the patients were categorized as being at risk of undernutrition. Care dependency and appetite were the two risk factors with the highest predictive value for an unfavorable nutritional status. CONCLUSION: Of Dutch elderly patients with Parkinson's Disease 22.5% had an unfavourable nutritional status. Dependency and appetite were the two risk factors with the highest predictive value fort his outcome. Because undernutrition can be regarded as a geriatric syndrome a comprehensive nutritional assessment should be done followed by nutritional interventions next to interventions focused on the risk factors. Further studies are needed to evaluate these interventions.
