Summary: | Introduction: The correlation between pulmonary function and hypertension remains ambiguous. This study therefore determined the relationship between pulmonary function and hypertension among adult subgroup in Malaysia. Materials and Methods: Data for this study were obtained from an ongoing Prospective Urban Rural Epidemiology-Rural Urban Study (PURE RUS), which is a prospective cohort study done by MARA University of Technology (UiTM) Medical Faculty research team to track risk factors, changing lifestyles, and chronic diseases in rural and urban population. The inclusion criteria included: Malaysian citizen, age 18–80 years, not on any anti-hypertensive agents, and able to perform lung function test. 1640 participants satisfied the criteria and were recruited in this study. Results: From the studied population, males comprised 43.5% of them and female comprised 56.5%. A significant inverse relationship was found between pulmonary function and systolic blood pressure in both sexes measured by forced vital capacity (FVC) and Forced Expiratory Volume in 1 second (FEV1). A substantial inverse relationship was also found between pulmonary function and age, and there was a profound positive association between blood pressure and age. No major disparities were significant in pulmonary function between hypertensive and age-matched normotensive participants. Conclusion: Even though a substantial inverse relationship was evident between systolic blood pressure and pulmonary function, its precise clinical importance needs to be further explored particularly when age can influence both pulmonary function and blood pressure. Clearly, the impact of age has to be removed before FVC can be used as a prognosticator of hypertension. © 2022, Malaysian Medical Association. All rights reserved.
