Malnutrition and related factors in Filipino patients with Parkinson's disease: results from a pilot study

Aim: Emerging evidence demonstrates a bidirectional relationship between nutritional status and Parkinson's disease (PD). Our aim was to determine the local prevalence of malnutrition and associated factors among Filipino PD patients. Materials & methods: We assessed the nutritional status of 95 PD patients using the body mass index (BMI) and Subjective Global Assessment (SGA) and identified malnutrition-associated factors. Results & conclusion: In our sample, the mean BMI was 24.5 +/- 4.2 kg/m(2). Consistent with published estimates, five (5.3%) patients were classified as underweight and 57 (60%) patients were classified as overweight/obese. A total of 30 (31.6%) patients had abnormal nutritional status based on SGA. Weight-adjusted levodopa equivalent daily dose was a significant factor (p = 0.032) for BMI, while dysphagia and higher weight-adjusted levodopa equivalent daily dose were found to be predictive of abnormal nutritional status using SGA (adjusted odds ratio of 8.85 [95% CI: 1.59-49.17; p = 0.015] and 1.10 [95% CI: 1.02-1.20; p = 0.021], respectively).
