Insufficient nutritional status is a frequent problem in the elderly, correlated with aging, diseases, but also environmental factors in this growing part of the population. Loneliness should be one of these factors.
the aim of the SOLINUT study was to determine the relationship between loneliness and nutritional status in persons aged over 70 years, in order to improve the detection and management of the isolated elderly at high risk of malnutrition. It was both an epidemiological and cross-sectional anthropological study, based on quantitative and qualitative nutritional and sociological investigation, carried out between March 2002 and May 2003 in 150 elderly persons (mean age 80.8 years, oldest subject 99 years) living alone at home.
a large number of subjects had a dietary intake which was inadequate to cover their nutritional needs--42.6% less than 25 kcal/kg/day, threshold for undernutrition in the elderly--21.3% had established undernutrition, ( average in epidemiological studies in non isolated elderly populations: 3-7%)--44% were not able to carry a shopping bag weighing 5 kg and so could not buy their own food. Lastly, 32% never shared a meal with family or friends, which reveals their degree of social isolation.
It has been demonstrated that greater coordination between the various service providers would prevent a large number of isolated persons from failing to obtain the various allocations and services available to them. We must stress the extreme importance of preemptive intervention, by an active screening policy which could simultaneously prevent undernutrition and encourage physical activity in isolated persons to avoid their becoming "excluded recluses".
营养状况不佳是老年人中常见的问题，与衰老、疾病以及这一不断增长的人群中的环境因素相关。孤独应该是其中一个因素。
SOLINUT研究的目的是确定70岁以上人群中孤独与营养状况之间的关系，以便改善对有营养不良高风险的独居老年人的检测与管理。这是一项基于定量和定性营养及社会学调查的流行病学和横断面人类学研究，于2002年3月至2003年5月在150名居家独居的老年人（平均年龄80.8岁，最年长者99岁）中开展。
大量受试者的饮食摄入量不足以满足其营养需求——42.6%的人摄入热量低于25千卡/千克/天，这是老年人营养不良的阈值——21.3%的人已出现营养不良（非独居老年人群体流行病学研究中的平均水平为3%-7%）——44%的人无法拎起5千克重的购物袋，因此无法自行购买食物。最后，32%的人从未与家人或朋友一起用餐，这揭示了他们的社会隔离程度。
事实证明，各服务提供者之间加强协调能够防止大量独居者无法获得他们可享有的各种津贴和服务。我们必须强调通过积极筛查政策进行预防性干预的极端重要性，这一政策能够同时预防营养不良，并鼓励独居者进行体育活动，以避免他们成为“被排斥的隐士”。
