Semisupervised Physical Exercise and Lifestyle Counseling in Cardiometabolic Risk Management in Sedentary Adults: Controlled Randomized Trial (BELLUGAT)

Evaluating the Potential of a Novel Metabolic Syndrome Severity Score to Inform Exercise Interventions for People with Complex Chronic Conditions

Aims: Exercise interventions positively affect numerous cardiometabolic risk factors. To better evaluate the health effects of exercise training, it may be more appropriate to evaluate risk factors together. The Metabolic Syndrome Severity Score (MetSSS) is a composite score representing cardiometabolic risk. Purpose: To evaluate the relationships between physical activity, neuromuscular fitness, exercise capacity, and the MetSSS in a heterogenous sample of people with complex chronic disease. Material and Methods: Fifty-three people with kidney or liver disease and at least one feature of the metabolic syndrome (MetS) were included. Pearson correlations were conducted between physical activity, neuromuscular fitness, exercise capacity, and the MetSSS. Linear regressions were performed for multi-level categorical variables. Independent variables with an association with MetSSS (P ≤ 0.2) were included in a multiple regression analysis. Results: The 6-minute walk test (6MWT) distance was inversely and independently associated with MetSSS [standardized beta coefficient (β) = -0.31, P = 0.04]. No relationship was found between MetSSS and physical activity or neuromuscular fitness. Mean 6MWT in the highest tertile was 550 m (range: 505-620 m) and 346 m (range: 233-408 m) in the lowest. The analysis showed a medium-large between-group effect for the difference in MetSSS for the lowest and highest tertile of 6MWT [Eta squared (η2) = 0.16, P = 0.01]. Conclusions: Exercise capacity was inversely and independently associated with MetSSS in people with complex chronic disease. Clinical trials with exercise interventions are needed to further investigate if improvements in exercise capacity result in clinically significant changes in the MetSSS.

Adherence to secondary prevention measures after acute coronary syndrome in patients associated exclusively with the public and private healthcare systems in Brazil

Adherence to secondary prevention measures after acute coronary syndrome (ACS) is essential to prevent disease recurrence. In Brazil, the Brazilian Unified Health System (SUS, in Portuguese), and the private healthcare system (PHCS) coexist. We aimed to evaluate the adherence to secondary prevention in patients with ACS who were assisted by either SUS or PHCS. In this longitudinal prospective study, patients with ACS were admitted to the four cardiological reference hospitals of Sergipe, three of which assisted PHCS users, and one, SUS users. We analyzed the two patient care models with multiple logistic regression models for adherence to physical activity, pharmacotherapy, and smoking cessation. We enrolled 581 volunteers in this study: 44.1 % from SUS and 55.9 % from PHCS. PHCS users showed greater adherence to pharmacotherapy at both 30 and 180 (p = 0.001) days after ACS with better results in all classes of medications (p < 0.05) than SUS users did. They also showed better adherence to physical activity (p = 0.047). There was no distinction between the groups regarding smoking cessation. The secondary prevention measures after ACS were more effective in PHCS users than in SUS users due to better adherence, especially to pharmacotherapy and regular physical activity.
