Carotid atherosclerosis and cardiovascular risk factors: a comparison of residents of a rural area of Okinawa with residents of a typical suburban area of Fukuoka, Japan

Areas of Japan are known worldwide for the longevity of their residents. Okinawa has the highest longevity in Japan and a low rate of death due to cardiovascular disease. We investigated carotid atherosclerotic (CA) risk factors in islands of I city in Okinawa prefecture and compared them with K tow...

Description
Summary:Areas of Japan are known worldwide for the longevity of their residents. Okinawa has the highest longevity in Japan and a low rate of death due to cardiovascular disease. We investigated carotid atherosclerotic (CA) risk factors in islands of I city in Okinawa prefecture and compared them with K town, a suburban area of Fukuoka prefecture in Kyushu, to determine the relationship between cardiovascular risk factors and carotid atherosclerosis. We investigated conventional cardiovascular risk factors in 1078 I city residents (375 men, mean age 63.7 and 703 women, mean age 60.0) in 2000 and 2364 K town residents (676 men, mean age 57.1 and 1688 women, mean age 53.0) in 1999. Carotid atherosclerosis was assessed by mean intima-media thickness (IMT) by B-mode ultrasound. The mean IMT was significantly lower in the residents of I city than in those of K town ( P
