Chagas heart disease is associated with decreased physical activity levels: A cross-sectional analysis.

Background

Studies evaluating physical activity (PA) levels in individuals with Chagas disease (CD) are still scarce. The present study aimed to evaluate PA levels in CD individuals and examine their association with Chagas heart disease (ChHD).

Methods

We included patients with CD regularly followed in a reference center for treatment of infectious diseases. PA levels were assessed using the short version of the International Physical Activity Questionnaire (IPAQ). ChHD was determined following the Brazilian Consensus on Chagas Disease. The association between ChHD and levels of PA (total, walking, moderate, and vigorous) as a continuous variable was fitted using generalized linear models. Logistic regression models were fitted to evaluate the association between ChHD and meeting WHO's PA recommendations.

Results

Among the 361 participants included in the analysis (60.7 ± 10.7 years; 56.2 % women), 58.1 % (n = 210) complied with the WHO's PA recommendations. After adjustments for potential confounders, regression analyses revealed that ChHD without heart failure was significantly associated with reduced vigorous PA (Exp β 0.32 95 % CI 0.10 to 0.98). ChHD with heart failure had significantly lower levels of total (Exp β 0.61 95 % CI 0.44 to 0.84) and moderate (Exp β 0.59 95 % CI 0.39 to 0.89) PA. ChHD with heart failure had a lower odd of meeting the PA recommendation in comparison to those with no cardiac involvement (OR 0.48 95 % CI 0.24 to 0.97).

Conclusions

We found low levels of PA among individuals with CD. Presence of ChHD (mainly with HF) was associated with decreased levels of PA.
