Relationship between sitting time and health status in patients with heart failure

Objective

To describe self-reported sitting time (ST), and determine the factors associated with health status (HS) among patients with heart failure (HF).

Methods

A cross-sectional study design was used in this study. Outcome measures included an international physical activity questionnaire and a self-report health status questionnaire. The data assessments were examined using the Pearson correlation coefficient, t-test, one-way ANOVA, and Hierarchical multiple regression.

Result

180 respondents joined this study. The mean age was mean 59.92 (SD= 11.90) years old, and 60% were male. The mean score of HS was mean 9.43 (SD= 2.16). The HS had a significant correlation with age (r= .17, p< .05), Hemoglobin (r= −.46, p< .01), HF medications (r= .31, p< .01), length of diagnostic HF (r= .35, p< .01), and comorbidity (r= .25, p< .01), and the HS was associated with the NYHA Classification (F= 203.43, p< .001), and the ST (F= 73.97, p< .001). Four variables were significant predictors of HS such as comorbidity (β = .14), NYHA Class I (β= –2.22), ST 6 to 8 hours/day (β= 1.27), and ST > 8 hours/day (β= 3.03), and they were predicted 75.1% of the variance in HS.

Conclusion

High amounts of ST and high NYHA classifications were associated with decreased HS in patients with HF, Moreover, HS is independently associated with comorbidities status and length of diagnostic HF.
