Some 2600 elderly people born between 1913 and 1918 have been enrolled in the Euronut SENECA study. In 12 European countries they were randomly selected from the resident populations of 19 'traditional' towns, mostly with a population size between 10,000 and 30,000 inhabitants. Site characteristics of these towns differ from mainly rural to urban and from lowland to mountainous with a range of temperate climates. In the rural areas work opportunities are primarily agricultural whereas in mixed rural/urban, suburban and urban areas most of the working population are engaged in industry, administration and commerce. The percentage of people over the age of 65 ranged from 8% to 22%. Medical and social facilities for the aged vary widely from site to site.
约2600名出生于1913年至1918年之间的老年人参与了欧洲营养老年研究（Euronut SENECA）。在12个欧洲国家，他们是从19个“传统”城镇的常住人口中随机挑选出来的，这些城镇大多人口规模在1万至3万居民之间。这些城镇的地点特征各异，从主要农村到城市，从低地到山区，气候温和多样。在农村地区，工作机会主要是农业方面的，而在农村/城市混合、郊区和城市地区，大多数劳动人口从事工业、行政和商业。65岁以上人口的比例在8%至22%之间。各地为老年人提供的医疗和社会设施差异很大。
