Nutritional status predicts primary subclasses of T cells and the lymphocyte proliferation response in healthy older women.

Aging is often associated with a dysregulation in immune function, particularly in T-cell responses, even in the healthy elderly. Adequate nutrition is important for optimal immune function. The literature on the relation of nutritional status with immune function in the elderly offers mixed findings.

Immune function is impaired in iron-deficient, homebound, older women.

Background: Aging is often associated with a dysregulation of immune function. Iron deficiency may further impair immunity in older adults. Published reports on iron deficiency and immune response in humans are inconsistent.

Inter- and intra-individual variation in tests of cell-mediated immunity in young and old women.

Exploring means to maintain or improve immunity in older persons has been receiving attention. To establish relationships between immune function and variables of interest, it is important to determine these variables accurately and precisely. Precision relates to the degree of variation in the laboratory test.
