By means of statistical analy sis of the obtained data, we made the questionnaire consisting of23scales with195items concerning food habits, behavior patterns, health condition, personality and value system. 2)A main survey was carried out in seven different regions(five for female and two for male respectively), in which5894adult females and914adult males were chosen. 3)Reliability coefficients were obtained from the result of principal component analysis based on items for each scale. The values of reliability coefficients ranged from0. 486to0. 845. Some scales with lower values should be necessary to be modified to some extent in the near future. 4)For evaluating life habits, the mean values of the23scales were calculated separately for each sex. Significant differences are found among some scales stratified with respect to ages, sexes and medical histories. 5)Six factors were extracted by means of varimax rotated factor analysis, which were useful for grasping life habits for both sexes
