Epidemiological Study of Eating Habit of Middle-Aged and Elderly Women: Mihara and Hiroshima Questionnaire Study.

Objective: Japanese women became the top class for average life span. We performed this study to clarify the reasons that contribute to the top class for average life span. Design: A clinical study. Materials and Methods: In this study we focused on the daily eating habit. Subjects are middle-aged and elderly women of Mihara and Hiroshima. We have done medical lecture, examination and questionnaire in Mihara over IS years ago as one of open campus projects. We compared the result of questionnaire between 1998 and 2012 in Mihara as longitudinal study. We compared the result of same questionnaire in Hiroshima as cross-sectional study in 2012. Results: Mihara women at both times had the same good eating habit of taking much vegetable, calcium actively and fish. Milk consumption has decreased and yogurt has increased as calcium resources. Calcium resources have changed yogurt from milk at now in Mihara. Demands of imported materials as coffee and wine have increased for IS years. Both area women kept the same good eating habit of taking much vegetable and calcium actively. Conclusions: In this our epidemiological study we speculated that food habit of Japanese women have become much richer and that this is one of the reasons that contribute to the top class for average life span.
