| Abstract |
The study investigated the relationship between physical activity and arterial stiffness in Chronic Obstructive Pulmonary Disease. A total of 154 office workers aged over aged 50 years were voluntarily recruited from S-office. Along with pulmonary function index, level of physical activity including walking, moderate, vigorous and total, brachial ankle pulse wave velocity, ankle-brachial index, and lipid profile were measured using standardized protocols. The participants were classified according to COPD stage using the international Gold stage according to FEV1(% predicted). The data were analyzed using descriptive analysis, one-way ANOVA, pearson’s correlation coefficients, chi-square dis- tribution, and logistic regression by the SPSS WIN 18.0 program. The COPD subjects had greater ba-PWV and lower pulmonary function indexes than the control subjects, and that difference was associated with lower level of physical activity including walking, Mod PA, Vig PA, Total PA. We also observed higher ba-PWV in the COPD subjects with severe COPD than in the subjects with mild to moderate COPD. The current findings of the study showed that poor physical activity was the risk factors of COPD and ba-PWV, implying the urgent need for a health lifestyle modification along with enhanced physical activity. |
