[Association between hypertension and pulmonary function in rural adults in Korea].
OBJECTIVE
Whilst hypertension exerts a negative effect on several organs there have been few studies regarding its effect on pulmonary function. The objective of this study was to examine the relationship between hypertension and pulmonary function in rural Korean adults.


METHODS
In 2006, 2534 people were recruited, aged 40 to 70, in Kangwha County. We selected 1454 (male: 624, female: 830) participants whose pulmonary function results were repeatable. Blood pressure (BP) was measured twice and the average calculated. Participants were divided into two groups (hypertensive group and non-hypertensive group) in accordance with The Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure. Pulmonary function was measured by dry rolling seal spirometry. Forced expiratory volume in the one second and forced vital capacity were converted into percent-predicted values based on average pulmonary function amongst Koreans.


RESULTS
The number of hypertensive participants in the present study was 460 (male: 205, female: 255) and the number of non-hypertensive participants was 994 (male: 419, female: 575). Our findings have shown that the mean values for expiratory volume in the one second and forced vital capacity were significantly lower for hypertensive people than for non-hypertensive people, among women (P=0.002 for forced expiratory volume in the one second, P<0.001 for forced vital capacity volume). Odds ratio analysis revealed that hypertensive participants were more likely to have lower pulmonary function than non-hypertensive participants, again significantly among women.


CONCLUSIONS
The pulmonary function of hypertensive women was significantly lower than that of non-hypertensive women aged 40-70.
