To clarify the present nutritional state of aged people and its relation to the Family Constitution in the life-cycle, a study was done, and the following results were obtained. (1) Observing by family type, C-type (old couples only) was superior in intaking all the nutrients and main foods, followed by N-type (couple and children; nuclear family), whereas, MN-type (old mother, younger couple and children) and CN-type (old couple, younger couple and children) were not so good as the other two types. (2) As to the nutrition intakes of the individual elderly persons, both men and women of C-type were found to be best in intaking nutrients, especially, energy and protein intakes of the men were over the allowances of their age. Accordingly, more obese persons were found in this type than other types. The worst nutritional condition was seen in couples of CN-type, protein intake being below the allowance in both men and women. Especially, the status of the wife in this type was inferior. A similar tendency was seen in the elderly women in MN-type. (3) The younger couples in CN- and MN-type were not so bad in taking nutrients as seen in their parents, but their children were in an inferior state. (4) In regard of the food expenditure, C-type family was in the top level, followed by N-, MN- and CN-type families. This order is coincident with nutrition intakes. Engel's coefficient was in the reverse order. The food expenditure of the individual aged men and women showed the same tendency as in family types. Among them, the women in CN-type spent less expense on their foods. From the above facts it is clear that the dietary condition of the aged is strongly influenced by the economical factors induced by the constitution of family, and that the families of C-type (old couples only), are in a stabilizied state in regard of their dietary life, as long as they are healthy.
