The impact of nutrition KAP (knowledge attitude and practice) and retention was examined among participants who were assessed at program entry 3 times of education and 1 month of follow-up. The results were as follows : The participants were composed 52 persons of under 60-year-old and 31 persons over 60 years. Of the 83 participants, 60 were females and 23 were males. Serum albumin and calcium content of females (3.5$pm$1.2g/dl, 7.5$pm$3.9mg/dl) were significantly lower than males(4.7$pm$0.9g/dl, 11.2$pm$4.6mg/dl). Serum TG and cholesterol contents of females (143$pm$117mg/d1, 205$pm$31mg/d1) were higher than males (101$pm$86mg/dl, 192$pm$19mg/dl) but not significantly different. The calcium (13.4$pm$9.0mg/dl) and urea (743$pm$440mg/dl) contents of urine excretion were also significantly lower in female than in males (19.7$pm$11mg/dl, 1041 $pm$535mg/dl). Via the question of nutrition attitude, the participants improved significantly between pre and post education (the score of pre, post and after 1 month, 6.7$pm$1.8, 7.2$pm$1.5, 7.2$pm$1.8), and were also attributed to better personal feeling health by modified CMI test but food habit was not significantly improved.
