Background/Objectives: Old age and illnesses can limit physical activity (PA). We have assessed the level of PA and its limitations in older people with diabetes (DM). Methods: Cross-sectional study, period: January and June 2024, place: Diabetes Center, subjects: patients (N = 207) > 64 years with DM), Surveying using: IPAQ, Accompanying Survey (AS). The significance was assessed by: Student's t -test, Mann-Whitney U test, Pearson's test. The relationships between the IPAQ and the AS results were analyzed based on a meta-analysis model for variable effects, OR with a 95% CI. ROC curve was used to determine the threshold values for age, BMI. Correlations between selected key variables were evaluated using the PCA. Results: The median age: 72 years (65-87), BMI: 28.70 (18.61-49.69). The median PA level: 1837 MET-min/week (0-9.891). The individuals who obtained insufficient (n = 28), sufficient (n = 75), and high levels of PA (n = 53) were 17.95%, 48.08%, and 33.97%, respectively. Diseases were the main factor limiting PA (53.54%) in patient's opinion, followed by the lack of a companion or motivation. The meta-analysis found no diseases linked to insufficient PA, but those with BMI > 33.3 and over 75 years old more often had insufficient PA. PCA revealed several characteristics that predispose individuals to insufficient PA. Conclusions: People over 75 years of age tend to avoid PA more than younger seniors, leading to its insufficient level, similarly like higher BMI. The individual with DM who has an insufficient level of PA is typically a single, woman, over 75, BMI > 33.

Background and Aim: Physical activity (PA) can modulate the immune response, but its impact on infectious disease severity is unknown. We assess if the PA level impacts the severity of COVID-19., Methods: Prospective, cohort study for adults hospitalized due to COVID-19, who filled out the International Physical Activity Questionnaire (IPAQ). Disease severity was expressed as death, transfer to intensive care unit (ICU), oxygen therapy (OxTh), hospitalization length, complications, C-reactive protein, and procalcitonin level., Results: Out of 326 individuals, 131 (57; 43.51% women) were analyzed: age: median-70; range: 20-95; BMI: mean-27.18 kg/m²; and SD: ±4.77. During hospitalization: 117 (83.31%) individuals recovered, nine (6.87%) were transferred to ICU, five (3.82%) died, and 83 (63.36%) needed OxTh. The median for the hospital stay was 11 (range: 3-49) for discharged patients, and mean hospitalization length was 14 (SD: ±5.8312) for deaths and 14.22 days (SD: ±6.92) for ICU-transferred patients. The median for MET-min/week was 660 (range: 0-19,200). Sufficient or high PA was found in recovered patients but insufficient PA was observed in dead or ICU-transferred patients ( p = 0.03). The individuals with poor PA had a higher risk of death (HR = 2.63; ±95%CI 0.58-11.93; p = 0.037). OxTh was used more often in the less active individuals ( p = 0.03). The principal component analysis confirmed a relationship between insufficient PA and an unfavorable course of the disease., Conclusion: A higher level of PA is associated with a milder course of COVID-19.
