Eating less the logical thing to do? Vulnerability to malnutrition with advancing age: A qualitative study

The aim of this qualitative inquiry was to explore older New Zealanders perspectives and experiences of food and nutrition intake, to gain insights to factors that influence vulnerability to malnutrition risk at older age. Participants represented an ethnically diverse group of nutritionally vulnerable older adults (five malnourished and nine at risk), with most participants identifying as having an illness severity of moderate or severe. Thematic content analysis was performed using an integrated approach and took into account participants' nutritional status as determined using the Mini Nutritional Assessment-Short Form. Six key themes emerged. Almost all participants reported they had reduced their food intake and felt that eating less, was the 'logical' thing to do as they were now undertaking less physical activity. They described eating as a chore; they ate because they 'had to keep going', but hardly ever felt hungry (low appetite); they had lost interest in eating, and no longer found food fanciful. Being in the company of others encouraged eating except in stressful situations such as caring for an ill spouse. They had a preference for foods they had grown up with but could no longer readily access or needed to avoid some foods because of coexisting conditions or illnesses, food intolerance and chewing difficulties. Finally, participants tried to eat foods best for their health. The notion of healthy eating as consuming "more vegetables" was widely held, with some participants explaining this meant "less fat and less sugar". Overall, the low food intake reported by these participants appears shaped by a myriad of sociocultural and health related factors. The findings can be used as a foundation to develop strategies for preventing vulnerability to malnutrition with advancing age.
