BrokpaとUnpa における血圧と年齢相関の比較

Abstract

Dirang Circle locates in the west of Arunachal Pradesh, north East part of India. Monpa ethnic people live there. Monpa ethnic is classified into two groups having different life styles. One group is mainly nomad, Brokpa. The another group is mainly agriculturist, Unpa. Brokpa people live at more than about 3000m altitude in mountains of Arunachal Pradesh. They go to higher mountain to do stock farming during summer seasons and live at their village (lower altitude) during winter season. Whereas, the Unpa people live at about 1500-2500m altitude, and settle in house and do farming throughout the year. Health check up was carried out two times (November 2009 and August 2010) in 6 places of Dirang Circle. 109 Brokpa and 174 Unpa people joined in the health check up. We investigated correlation between SBP (Systolic Blood Pressure) and age in Bropka and Unpa. As the results, we found significant correlation between SBP and age both in Brokpa (r=0.36, p<0.01) and in Unpa (r=0.32, p<0.001). It is postulated that the rise of blood pressure with advancing age, observed in the great majority of the groups, is a consequence of modernization. Although Brokpa and Unpa people appear to continue traditional life style now, however, it is supposed that so-called traditional lifestyle might be gradually changing with the effect of global modernization as the correlation between age and SBP both in Brokpa and in Unpa people had suggested.
