[A follow-up study of the elderly in agricultural and piscatorial areas of Hokkaido].
A base-line survey was performed for 3,185 persons over 40 years of age in 1984 and 1985 in agricultural and piscatorial areas of Hokkaido with regards to their dietary habits and life style. Of them, 147 persons died prior to the recent follow-up survey of 1988. As a result of a case-control study of the dead with those of the followed-up group, a more frequent intake of instant noodles was indicated as significantly increasing the risk of death, even after adjusting for the health status at the base-line survey and other confounding variables (the adjusted relative risk = 1.44 per a frequency class, p = 0.049).
