title: Lipid profiles, serum immunoglobulins, dietary intake, and drug use of older rural Iowa women.
abstract: Serum lipid profiles, serum immunoglobulins, and serum proteins were investigated in 65 noninstitutionalized older women living in a rural community. All women were mentally and physically able to participate in the study. They did not have any overt disease nor were they taking any prescription or nonprescription drugs that would interfere with the study. Personal interview elicited medical history, drug usage, dietary information, height, and weight from 25 reference women (50 through 64 years old), 28 young-old women (65 through 84 years old), and 12 old-old women (85 through 92 years old). Blood samples were obtained from fasting participants and analyzed for total serum cholesterol, high-density-lipoprotein cholesterol, serum triglyceride, serum immunoglobulins (IgG, IgA, and IgM), serum albumin, and total serum protein. Serum lipids were not significantly affected by age, drug use, or age-by-drug use interaction. Effects of age were observed for IgA and serum albumin. Mean concentrations of serum immunoglobulins, serum albumin, and total serum proteins were within normal limits for all participants. Based on this small sample of rural older women, our results indicate that the normal levels of high-density-lipoprotein cholesterol and the healthy life-styles of these women may help offset any possible negative effects of elevated serum cholesterol concentrations.
