Background: For developed countries, healthy aging is one of the challenges and the number of healthy life years and especially the quality of life (QoL) are important. Objective: This study aimed to assess the association between nutritional status and different domains of QoL in (pre)frail community-dwelling elders. Design: Baseline data from persons, who participated in a 12-week nutritional and physical training intervention program, conducted from September 2013 - July 2015. Setting: (Pre)frail community-dwelling elders living in Vienna, Austria. Participants: A total of 83 older persons living at home, 12 men and 71 women (86%) aged 65 to 98 years. Measurements: Structured interviews were conducted at participants’ homes. Mini Nutritional Assessment® long-form (MNA®-LF) was used to investigate the nutritional status. The QoL domains were assessed with the World Health Organization Quality of Life questionnaires. Simple and multiple linear regression analyses were performed to evaluate the association between nutritional status and QoL domains, adjusted for possible confounders. Results: 45% of the participants were at risk of malnutrition and 3% were malnourished. Compared to normal nourished people, persons who had an impaired nutritional status, significantly differed in the QoL domain ‘autonomy’ with mean (SD) scores of 50.0 (14.9) vs. 57.3 (13.7); p=0.022 and in the QoL domain ‘social participation’ with scores of 40.1 (13.6) vs. 47.0 (11.2); p=0.014, respectively. According to linear regression analyses, the MNA®-LF score was significantly associated with ‘overall QoL’ (β=0.26; p=0.016) and the QoL domains ‘physical health’ (β=0.23; p=0.036), ‘autonomy’ (β=0.27; p=0.015), and ‘social participation’ (β=0.28; p=0.013). Conclusions: There was a significant association between nutritional status and QoL in elderly (pre)frail community-dwelling people, in particular for the QoL domains ‘autonomy’ and ‘social participation’. However, it remains unclear whether malnutrition was the cause or the consequence, or it was mediated through a third possible factor e.g. the functional status.
