# Association Between Physical Activity, Sedentary Time, and Quality of Life in Patients with Chagas Disease During COVID-19 Pandemic in Brazil: A Cross-Sectional Study

## TL;DR

This study found that higher physical activity improves quality of life for Chagas disease patients during the pandemic, while more sedentary time worsens it.

## Contribution

The study is the first to explore the relationship between physical activity, sedentary time, and quality of life in Chagas disease patients during the pandemic.

## Key findings

- Higher total physical activity is linked to better psychological and environmental quality of life.
- Moderate-to-vigorous physical activity improves physical and psychological quality of life.
- Increased sedentary time is associated with reduced physical quality of life.

## Abstract

Background: COVID-19 led to social isolation, potentially reducing physical activity (PA), increasing sedentary time, and lowering quality of life (QoL). This study investigated the association between these factors in patients with Chagas disease (ChD) during the pandemic. Methods: This cross-sectional study included 187 patients with ChD. PA and sedentary time were assessed by the IPAQ-short and QoL by the WHOQOL-Bref. The relationship between PA levels and sedentary time with QoL were assessed using unadjusted and adjusted generalized linear models. Results: The highest tertile of total PA was positively associated with the psychological (Exp β = 1.11; 95% CI: 1.02–1.22) and environmental (Exp β = 1.12; 95% CI: 1.01–1.23) QoL domains. The intermediate (Exp β = 1.12; 95% CI: 1.01–1.25) and highest (Exp β = 1.14; 95% CI: 1.02–1.27) tertiles of moderate-to-vigorous PA were positively associated with the physical domain. Similarly, both the intermediate (Exp β = 1.11; 95% CI: 1.01–1.22) and highest (Exp β = 1.12; 95% CI: 1.01–1.21) tertiles of moderate-to-vigorous PA were positively associated with the psychological domain. The highest tertile of sedentary time was associated with a decrease in the physical domain (Exp β = 0.88; 95% CI: 0.79–0.98). Conclusions: Higher levels of total and moderate-to-vigorous PA were associated with better QoL, while greater sedentary time was associated with poorer QoL.
