| Research Abstract |
The relationship between life styles and mortality were analyzed using three municipality cohorts which consisted of 2889 participants without past history of stroke, myocardial infarction, or cancer. Participants who slept more than eight hours a day had 3.4 times increased risk of total death compared with participants who slept 7 to 8 hours among younger subjects (aged 40-59 years). Participants who walked 30 minutes or more a day had 40 percent reduced risk of death compared with participants who walked less than 30 minutes among older subjects (aged 60-79 years). Participants who drank natural juice more than three times a week had 48 percent reduced risk of death compared with participants who had it two times a month or less among younger subjects. Participants who drank more than two units (go) of sake had 3 times increased risk of death compared with participants who drank one unit of sake or less among younger subjects. Smokers had 1.7 times increased risk of death compared with non-smokers among older subjects. Participants who said they had nothing to live for had 1.7 times increased risk of death compared with participants who felt they had something to live for among older subjects. Participants who had 5 or 6 favorable habits out of the above 6 habits had 64 percent reduced risk of death compared with participants who had 2 or less habits. In a cross-sectional study of activities of daily living (ADL), ADL impairment was relsted to past histories of stroke, hip fracture, or diabetes mellitus. In a cohort study linked with the ADL survey, excess death or ADL impairment was related to sleeping 8 hours or more, walking less than 30 minutes a day, drinking two units or more of sake per day, smoking, and a feeling of having nothing to live for.
