title: [Swiss Survey in Europe on Nutrition and the Elderly: nutritional status of a Yverdon population aged 74 to 79 years old over a period of four years].
abstract: In Switzerland the longitudinal SENECA study (Survey in Europe on Nutrition and the Elderly, a Concerted Action of the 3rd European Framework Programme) was implemented in the city of Yverdon-les-Bains. The study investigated the nutritional and health status of 70 to 75-year old elderly living at home, in relation with their food habits, life style, social network and physical activity with a follow-up study 4 years later. Results of the follow-up study, with the subjects aged 74 to 79 years, and changes observed over the 4 years are presented here. The participants reported a rather good self-assessed health and were quite independent in their daily activities. Food and nutrient intakes decreased over the 4-year follow-up, as did physical activity, independence in daily activities and height. However, biological markers (haemoglobin, haematocrit, albumin, lipids and vitamins) of nutritional status showed little change and remained mostly in the normal range. Low energy intake was measured in 21% of the men (< 1500 kcal/d) and in 24% of the women (< 1200 kcal). This is a source of concern since such low energy intakes make it difficult to cover micronutrient requirements. It is therefore important to find ways to maintain or increase the quality of the diet and adequate nutrient intakes.
