Prospective study of educational background and XXXX in Japan.

@entity5 @entity1 @entity167 @entity204
BACKGROUND: Different lifestyle choices are commonly regarded as a reflection of socioeconomic status, and the latter is inversely correlated with the risk of developing @entity5 . However, the details of this association are still unclear in terms of the degree to which lifestyle factors are having impact. To explain the correlation between socioeconomic status and @entity5 , we therefore examined the roles played by different lifestyle factors. METHODS: A prospective cohort study of diet and @entity5 was initiated in Japan during 1988. Data were collected by means of a self-administered questionnaire. A follow-up survey was conducted annually, and the cause of @entity204 was recorded from the @entity204 certificate. The total of 127,477 study @entity1 resided in 45 areas of Japan, and we retrieved data for 18,746 @entity1 and 26,184 @entity1 for the present analysis. After 328,030 @entity1 -years of follow-up, 379 deaths from @entity5 were detected: 261 in @entity1 and 118 in @entity1 . RESULTS: For @entity1 , the age-adjusted relative risk was lowest in the highly educated group (relative risk = 0.72, 95% CI: 0.50-1.04). Relative risk after adjustment for age and dietary choices (including pickles, vegetables, fruit, green tea, and preference for salty foods) was the same as the age-adjusted relative risk (relative risk = 0.72, 95% CI: 0.50-1.04). CONCLUSION: The expected inverse correlation between education level and @entity204 from @entity5 was observed in @entity1 . However, this association could not be explained by differences in dietary habits, smoking, or @entity167 consumption associated with socioeconomic status.
