Background

Patients with chronic obstructive pulmonary disease (COPD) have increased likelihood of hypertension, which may lead to increased mortality rates. This study investigated the incidence of hypertension in patients with COPD according to the levels of their physical activities.

Methods

This study used data from the fifth Korean National Health and Nutrition Examination Survey, conducted from 2010 to 2012, including 1,243 people aged 40 years or older with COPD who were cross-classified according to their levels of physical activity. The relevance of morbidity associated with high blood pressure was also evaluated through cross and logistic regression analyses.

Results

Among patients with COPD who performed moderate-intensity physical activities, the group without hypertension had 4.3% higher compared to the group with hypertension (P=0.012). Adjusted analysis for patient age, sex, body mass index, smoking, drinking habit, income, diabetes mellitus, hyperlipidemia, and energy intake performed to determine the relationship between physical activity level and hypertension revealed that patients with moderate-intensity physical activity had 53.6% lower (95% confidence interval: 0.288–0.997) incidence of hypertension.

Conclusions

The results of the current study suggest that patients with COPD who perform moderate-intensity physical activity have a lower incidence of hypertension.
