The present paper resents information on the dietary intake and biochemical status of elderly who are living in different types of residence. On hundred and sixty five women(age 65-80 years old) were divided into three groups ; those who are living alone (LA) , living with family (LF) , and living in institutions (LI) within the same general community. Nutrient intake, body fat content, and biochemical measurements in blood and urine were examined statistically and potential environment-related influence are discussed. Elderly women living alone had significantly lower intake of nutrients than elderly women were not living alone LF group showed significantly higher fat consumption than LA and LI groups. Body fat content, plasma albumin and calcium levels in elderly women who lived with other people were significantly higher than those in elderly women living alone, but fat weights and lean body mass between groups were not different. None of the plasma lipid fractions were significantly different among the three groups except LDL-cholesterol (LDL-C) concentration. In the LI group, LDL-C was lower than that of LF and LA groups. From the above results, serious nutritional deficiency has been shown in elderly women that live alone. Therefore, nutritional education and social help should be carried out to improve these situations for elderly people.
