This feasibility study of routine nutrition risk screening in community-dwelling older adults using a partnership between health care and community-based organizations (CBO) aimed to (1) evaluate the ability of community-based partnerships to provide screening for nutrition risk, and appropriately refer at-risk individuals for follow-up care and (2) determine the barriers to and facilitators of screening. Adults 65 years of age and older were screened by staff in two primary care and one CBO setting using the Seniors in the Community: Risk Evaluation for Eating and Nutrition (SCREEN)-8 nutrition risk screening tool. Screeners, organization administrators, and registered dietitians responded to surveys regarding SCREEN-8 administration, referral processes, and partnership interactions. All found the SCREEN-8 initiative feasible, acceptable, and appropriate. Sustainability requires strengthening of community resources, referral processes, and telephone assessments. The partnership added value despite limitations in communications. We conclude that broader implementation of this program using community-based partnerships has the potential to aid in the prevention of malnutrition in older adults.

Adequate intakes of micronutrients are required for the immune system to function efficiently. Micronutrient deficiency suppresses immunity by affecting innate, T cell mediated and adaptive antibody responses, leading to dysregulation of the balanced host response. This situation increases susceptibility to infections, with increased morbidity and mortality. In turn, infections aggravate micronutrient deficiencies by reducing nutrient intake, increasing losses, and interfering with utilization by altering metabolic pathways. Insufficient intake of micronutrients occurs in people with eating disorders, in smokers (active and passive), in individuals with chronic alcohol abuse, in certain diseases, during pregnancy and lactation, and in the elderly. This paper summarises the roles of selected vitamins and trace elements in immune function. Micronutrients contribute to the body's natural defences on three levels by supporting physical barriers (skin/mucosa), cellular immunity and antibody production. Vitamins A, C, E and the trace element zinc assist in enhancing the skin barrier function. The vitamins A, B6, B12, C, D, E and folic acid and the trace elements iron, zinc, copper and selenium work in synergy to support the protective activities of the immune cells. Finally, all these micronutrients, with the exception of vitamin C and iron, are essential for antibody production. Overall, inadequate intake and status of these vitamins and trace elements may lead to suppressed immunity, which predisposes to infections and aggravates malnutrition. Therefore, supplementation with these selected micronutrients can support the body's natural defence system by enhancing all three levels of immunity.
