The Age-Related Trend in Blood Pressure and the Prevalence of Hypertension in Korean Adults

Daetaek Lee; Yong-Soo Lee

한국인의 연령에 따른 혈압변화와 고혈압 유병률 그리고 수축기(SBP)와 이완기(DBP)혈압 및 맥압(PP)의 변화양상을 횡단적으로 평가하였다. 지역보건소 건강검진 및 건강증진프로그램을 통해 진료된 대상자 6,570명(남2,809, 여 3,761)을 5 연령군(30, 40, 50, 60대 그리고 70세 이상)으로 구분하여 비교 분석하였다. SBP는 지속적으로 증가하였으며, 남자가 여자에 비해 높게 유지되었다. 그러나 60대 중반에서 역전되었다. DBP는 남자 30대부터 증가하여 40대에서 최고점을 이르렀다가 하강하였다. 여자는 4-50대까지 증가하다가 일정한 수준을 유지하였다. 남녀 모두에서 PP는 50대 이후 가파르게 증가하였다. 남자의 경우 특히 50대 이후의 연령과 관계한 혈압의 증가는 큰동맥의 굳어짐 현상이 가장 큰 공헌을 하는 것으로 보이며, 여성의 경우는 큰동맥굳어짐, 일회심박출량 또는 심실박출율과 같은 다양한 원인에 기인하는 것으로 평가된다. PP의 증가는 심장에 부담을 주게 되며 특히 50대 이후 남녀 모두에서 가파른 위험성이 예견된다. 이 연구에서는 남녀 모두에서 고혈압 발병률이 이전의 연구들에 비해 높게 나타나고 있다. 높은정상혈압을 고혈압 위험군에 포함시킨다면 고혈압 관리를 위한 대상자의 범위는 상당히 확장될 것으로 보인다. 【A cross-sectional analysis of blood pressure (BP) changes and the current prevalence and distribution of hypertension among age groups in Korea were conducted. Systolic (SBP), diastolic (DBP), and pulse (PP) pressures were evaluated. Residents visiting a local Community Health Center for a health check-up and/or participating in the Health Promotion Program were included for the analyses. A total of 6,570 subjects (2,809 men, 3,761 women) were divided into five age groups: 30-39, 40-49, 50-59, 60-69, and

Aerobic Capacity and Ventilatory Response During Incremental Exercise in Elite High School Cyclist

years. Comparisons were made between sex and among age groups. SBP and DBP were continuously elevated, while men showed higher levels than women until their mid-60s; then, the trend was reversed. DBP in men became elevated from their 30s, reaching the highest in the 40s then slowly decreasing. DBP in women increased up to their 40s and 50s, then reached a plateau. PP increased rapidly from the 50s in both sexes. The major contributor of age-related BP elevation may be large artery stiffness in men, particularly from their 50s, while the blood pressure elevation of women may relate to diverse factors including large artery stiffness, stroke volume, and ventricular ejection rate. The rapid elevation of PP after the 50s in both men and women could represent a risk of cardiovascular or coronary mortality, particularly with increasing age. The current data showed a higher rate of hypertension in both sexes compared to previous reports. When those with both high-normal BP and hypertension are looked at in combination, BP management of the target population should be drastically elevated.】

[목적] 대한올림픽위원회(KOC)의 국제올림픽위원회(IOC) 인준은 1947년 6월 20일로 알려져 있다. 이는 1947년 6월 스톡홀름에서 열린 IOC 총회에서 한국의 국가올림픽위원회(NOC)가 인준되었다는 것을 근거로 한다. 그러나 현존하는 사료들은 인준과 그에 따른 조건 등이 알려진 바와 다른 방식으로 설명하고 있다. 본 연구의 목적은 KOC가 1947년 어떠한 방식으로 예비인준 되었고, 그 조건이 무엇이었으며, 관련 사안과 연계된 브런디지의 역할이 무엇이었는지를 규명하고 설명하는 것이다. [방법] 연구방법은 문헌연구이다. 연구대상 자료는 브런디지 컬렉션과 IOC 올림픽연구센터(Olympic Studies Center: OSC)가 소장한 아카이브 중 KOC의 인준과 관련한 자료를 검토하였다. [결과] 이 자료들에 의하면 KOC는 예비인준된 것이며, 예비는 한반도에서의 정부수립과 북한을 포함하여 수행되어야 하는 NOC로의 책임을 전제로 하였다. 한국 NOC의 불충분한 평가 환경에서도 인준이 가능했던 것은 브런디지의 역할과 판단이었던 것으로 보인다. [결론] 1947년 KOC의 인준과정과 조건은 KOC 역사가 새롭게 기술될 필요성을 제안한다. 또한 IOC는 KOC를 인준하면서 한반도가 한 국가이며 이를 전제로 인준하였고 북한을 포함하여 임무를 수행할 것을 요구했다. 브런디지의 역할은 재조명되어야 할 것이다.

This study was designed to examine the aerobic capacity and ventilatory response during an incremental exercise in elite high school cyclists. Twelve boys (, , ) participated in anthropometric measurements, incremental exercise testing, and pulmonary function tests. During incremental exercise testing using a cycle ergometer, their maximal oxygen uptake (), maximal power output, ventilation, ventilatory equivalents for oxygen () and carbon dioxide (), respiratory rate, and tidal volume were measured. Time variables such as inspiratory time (Ti), expiratory time (Te), breathing time (Tb), and inspiratory duty cycle (Ti/Tb), as well as inspiratory flow rate (/Ti) were assessed. Pulmonary function of vital capacity (FVC), forced expiratory volume in one second (), /FVC, and peak expiratory flow were evaluated. Their , maximal heart rate, and Wmax were , , and 452 W, respectively. was not related to any anthropometric parameters. Most ventilatory variables progressively increased with exercise intensity. As intensity increased, Ti, Tb, Tb decreased while Ti/Tb was maintained. Below an intensity of 250 W, height, weight, body mass index, and body surface were highly correlated with /Ti and Ti/Tb (p appeared to be lower than adult cyclists, suggesting a different pattern of ventilatory control as age advances. Morphological characteristics were not related to in the population. Time variables of ventilatory response seemed to be related only at an exercise intensity level of less than 250 W. /Ti may be related to exercise endurance capacity, but Ti/Tb was similar to adult cyclists.
