Summary

Evidence is required to ascertain whether improvement of nutritional status in older people in the community has important benefits and is an efficient use of health services resources. In total, 910 older, mainly non-institutionalised people were randomised to a daily multivitamin and multimineral supplement or placebo for one year. Primary outcomes were primary care contacts, self-reported days of infection and quality of life. Secondary outcomes included antibiotic prescriptions, hospital admissions, adverse events and compliance.
