Abstract [en]

Background & aim: Swallowing disturbances are associated with older age as well as with other subclinical disturbances of multifactorial origin in patients with Parkinson's disease (PD). This study assesses nutritional markers and whole-body impedance data to better understand swallowing disturbances in Parkinson's disease.

Design and patients included: This cross-sectional study includes baseline data from a cohort of newly diagnosed patients identified in the New Parkinsonism in Umeå study (NYPUM) (n = 75).

Methods: Swallowing disturbance was registered as a score of one or more on the Unified Parkinson's Disease Rating Scale (UPDRS) section II question number 7 on swallowing. The analysis used nutritional markers in plasma and anthropometry from bioimpedance.

Results: Bivariate analysis revealed that swallowing disturbances were associated with low plasma phosphate levels for males (r = −0.428; p = 0.005) and for all patients with PD (r = −0.241; p = 0.037). In males but not in females, a negative association was found between age and albumin and amount of intra-cellular water (ICW, l). Plasma albumin was associated with plasma phosphate (r = 0.315; p = 0.006; n = 75, r = 0.361; p = 0.036; n = 34, r = 0.310; p = 0.049; n = 41). Another risk pattern indicating swallowing disturbance in females was revealed by an association with visceral adiposity index (VAI), plasma triglycerides (TG), and triglyceride/high density lipoprotein (TG/HDL) ratio. The adjusted logistic regression revealed that low phosphate in males and low magnesium in females were risk factors for swallowing disturbance.

Conclusion: The age-related decline in plasma phosphate in males with PD may be an important nutritional marker for swallowing disturbances. Body composition measurements and nutritional markers provide information for the study of swallowing dysfunction as part of sarcopenia.
