Background and aim The aim of the present study was to assess the risk and the prevalence of undernutrition as well as associated factors among community dwelling elderly adults (home dwelling as well as nursing home residents). Methods During one week a questionnaire was completed in 70 general practices and in 70 nursing homes. The questionnaire was based on items from validated screening instruments such as the MNA (Mini Nutritional Assessment; short form), the SNAQ (Short Nutritional Assessment Questionnaire) and some additional parameters (mobility, independence, social isolation and co-morbidities). Results The study sample consisted of 5334 elderly of which 975 lived at home (Mean age: 83 years). Sixteen percent was older than 90. The overall risk for undernutrition (MNA ≤ 11) was 57%, and was significantly higher in nursing home residents, women and in the older age groups. Undernutrition was already present in 15.9% (BMI < 20 kg/m2), 17.1% (SNAQ) and 17.6% (clinical evaluation). Decreased mobility was associated with older age and undernutrition. Conclusions The overall risk of and the prevalence of undernutrition are common in older people. The prevalence is highest among the oldest, in women and in nursing home residents. Undernutrition and worsening mobility are interrelated.
