To investigate the importance and practice of well-being related dietary life pattern such as purchasing food materials, food habits and eating out, a survey was conducted by questionnaire and 5-point Likert score in Seoul and Gyeonggi-Do, September, 2004 and April, 2005. The responses of 732 housewives who were over 40 years were analyzed by SPSS package program. The results were as follows. Most of them were 40-49 years(74.4%), graduated highschool (66.6%) and their family type was nuclear family type(81.4%). Almost half of them had full-time job (37.1%) and part time job (15.4%). The average importance score of 'food habits', 'purchasing food materials' and 'eating out' were 4.15±0.91, 4.06±0.96 and 3.25±1.01 respectively. But the average practice score of 'food habits' was greater(3.58±1.06) than 'purchasing food materials (3.19±1.19)' and 'eating out(2.54±1.05)'. Among 5 types of 'food habits', the type of 'cut down on eating fast food' had the greatest score of importances (4.31±0.97) but the difference between importance and practice was greatest(0.94). Also 'consume home-made food rather than processed or ready to food' showed great scores in importance (4.28±0.87) and practice(3.87±1.04). 'Consume fruits and vegetables rather than meats' and 'avoid heavy use of oils' had the importance score of 4.04~4.19. But the practice score of 'avoid heavy use of oils' was the lowest(3.39±0.97). Among four types of purchasing of food materials, 'purchase domestic agricultural food' was greatest(4.37±0.78) and 'don't purchase genetically modified food' 'purchase organic food' and 'purchase whole grain products' were also great (3.92~3.99). But the practice score of 'purchase organic/low chemical foods(2.77±0.98)' and 'don't purchase genetically modified food(2.99±1.41)' were lowest. 'Go to well being restaurant' in three types of 'eating out' showed greatest in importance(3.35±0.96) but the practice score(2.47±0.10) was lower than the importance score. Also 'choose menu with comparing calories' had the lower score in practice(2.45±1.06) rather than importance score(3.22±1.03). In regarding to 'food habits', the importance score were significantly affected by type of food expense (p〈0.05) and health status (p〈0.05). The importance score of 'purchase food materials' were significantly affected by the type of food expense (p〈0.001), type of residence(p〈0.05), and self assessment of weight(p〈0.05). Monthly income, especially more 400 million won, was the commonly significant effector in practice score of 'purchase food materials' and 'eating out'.
