Abstract

Background: Whether body weight changes are associated with Parkinson's disease (PD) mortality remains uncertain. Objective: To investigate the association between changes in body mass index (BMI) and all-cause mortality in patients with PD. Methods: This nationwide cohort study enrolled 20,703 individuals with new-onset PD (ICD-10 code: G20 and a rare intractable disease registration code: V124) who underwent health screening program by the Korean National Health Insurance Service within two years from pre- and post-PD diagnosis. We identified nine BMI change groups based on three BMI status: underweight (BMI < 18.5 kg/m2), normal or overweight (18.5 kg/m2≤BMI < 25 kg/m2), and obese (BMI≥25 kg/m2). Results: Of 20,703 individuals, 3,789 (18.0%) died during the follow-up period. Excessive weight loss to underweight in the obese group (hazard ratio [HR] = 3.36, 95% CI:1.60–7.08), weight loss in the normal to overweight group (HR = 2.04, 95% CI:1.75–2.39), sustained underweight status (HR = 2.05, 95% CI:1.67–2.52), and weight gain from underweight to normal or overweight (HR = 1.52, 95% CI:1.15–2.02) were associated with increased mortality. Sustained obese status (HR = 0.80, 95% CI:0.74–0.87) and weight gain in the normal to overweight group (HR = 0.82, 95% CI:0.71–0.95) were associated with reduced mortality. Conclusions: We found that BMI change at diagnosis was associated with mortality in patients with PD. Specifically, being underweight either before or after diagnosis as well as experiencing weight loss, were associated with increased mortality. These findings provide valuable insights for weight management planning in PD, highlighting the importance of individualized approach that consider pre-diagnosis BMI. Plain Language Summary: Whether body weight changes are associated with Parkinson's disease (PD) mortality remains uncertain. This study looked at how changes in body weight affect the chances of survival in people who have recently been diagnosed with PD. We followed 20,703 individuals who were newly diagnosed with this condition and checked their weight changes before and after their diagnosis. We found that people with PD who lost a lot of weight to become underweight had a higher risk of dying during our study. Similarly, those who were already underweight and remained so also had a higher mortality risk. On the other hand, people who maintained a weight or gained a small amount of weight after their diagnosis had the lowest risk of dying. Our research found that weight changes at diagnosis were associated with mortality in PD, with underweight or weight loss being linked to increased risk of death. Each person's situation is different, so weight management should be tailored to each individual, considering their weight before they were diagnosed with PD. [ABSTRACT FROM AUTHOR]

Abstract

ObjectiveTo examine associations between the amount and changes in regular physical activity (PA) before and after diagnosis of dementia and all-cause mortality risk, and whether these associations differ by PA intensity (light, moderate or vigorous).MethodsThis retrospective cohort study used data from the Korean National Health Insurance Service Database, including 60 252 individuals newly diagnosed with dementia between 2010 and 2016 who underwent health examinations both before and after diagnosis. PA was assessed using the International Physical Activity Questionnaire–Short Form. Multivariable Cox proportional hazards regression models were used to analyse the associations between PA (amount and changes) and all-cause mortality risk.ResultsDuring a mean follow-up of 3.7 years, 16 431 (27.3%) deaths occurred. Higher PA levels after dementia diagnosis were associated with a dose-dependent decrease in mortality risk (p for trend <0.001). Maintaining regular PA, compared with remaining inactive, was associated with the lowest mortality risk (HR=0.71, 95% CI 0.65 to 0.79). Sustained engagement in PA of any intensity was associated with decreased mortality risk: light (HR=0.70, 95% CI 0.67 to 0.75), moderate (HR=0.74, 95% CI 0.64 to 0.86) and vigorous PA (HR=0.70, 95% CI 0.61 to 0.79). Initiating any PA intensity after dementia diagnosis was associated with at least 20% reduced mortality risk. These associations were consistent in Alzheimer’s disease.ConclusionsMaintaining or initiating regular PA, regardless of intensity, after dementia diagnosis was associated with a reduced risk of all-cause mortality. Lifestyle modifications promoting PA might offer survival benefits for individuals with dementia.
