The increasing size and longevity of the geriatric patient population dictates that all health care practitioners become more cognizant of the unique requirements for nutritional assessment and support of the elderly. This review summarizes recent advances in the understanding of the nutrition support needs of the old and oldest-old patients requiring enteral or parenteral feeding. When a nutrition support formula individualized for the geriatric patient is being developed, there is a fine line between excess and deficit, requiring the involvement of the entire support team in monitoring the success of feeding. Indications for choosing enteral or parenteral feeding are considered excessively invasive by some and necessarily "heroic" by others. The patient and his or her family should be part of the decision-making process.

To assess the validity of nutrient intake estimates from a food frequency questionnaire, the authors compared estimates of intake of preformed retinol (dietary plus supplements), beta-carotene, other active carotenoids, and total vitamin A computed from questionnaire responses with serum retinoid and carotenoid concentrations. Data were obtained from 302 male and female current or former smokers, participants in a lung cancer chemoprevention trial at the Fred Hutchinson Cancer Research Center in Seattle, Washington, during 1985-1986. Both serum beta-carotene and serum alpha-carotene were associated, although weakly, with food frequency estimates of total vitamin A intake, dietary vitamin A, beta-carotene, other carotenoids, and total carotenoids (0.18 less than or equal to r less than or equal to 0.26). Serum retinol was associated with supplementary vitamin A intake (r = 0.16). Nondietary factors were also associated with serum nutrient concentrations--in particular, cigarette smoking, alcohol intake, and body mass index. Cigarette smoking emerged as an important modifying factor of the relation between serum beta-carotene and dietary beta-carotene (r = 0.14 for current smokers, r = 0.30 for former smokers).
