Nutrition knowledge enables informed dietary choices. This paper reports on the nutrition knowledge of older adults residing in sheltered housing accommodation in socially deprived areas of north-east England.
As part of a cluster randomized dietary intervention trial, a validated questionnaire measured the knowledge of current dietary recommendations, nutrient sources, ability to select healthy meal options and knowledge of associations between diet and diseases of older adults aged 60 years and over residing in sheltered accommodation.
Completed questionnaires were obtained from 177 (59%) subjects (147 female, 30 male), of whom 76% were overweight/obese and 2% underweight. The mean (SD) age was 76.4 (8.0) years. Of a possible score of 47, the mean score was 23.2, indicating that approximately 50% of questions were answered incorrectly. Knowledge of associations between diet and diseases was particularly poor; 90% of subjects being unaware of the benefits of high fruit and vegetable consumption. Respondents in the highest 10% of the nutrition knowledge score had a significantly higher intake of fruit and vegetables compared with those in the lowest 10%.
A high proportion of older adults had little basic nutrition knowledge; this presents a barrier to healthier eating that should be addressed.
营养知识有助于做出明智的饮食选择。本文报告了居住在英格兰东北部社会贫困地区庇护性住房中的老年人的营养知识情况。
作为一项整群随机饮食干预试验的一部分，一份经过验证的问卷测量了60岁及以上居住在庇护性住房中的老年人对当前饮食建议、营养来源的了解，选择健康膳食的能力以及对饮食与疾病之间关联的认识。
共获得177名（59%）受试者（147名女性，30名男性）的完整问卷，其中76%超重/肥胖，2%体重过轻。平均（标准差）年龄为76.4（8.0）岁。在可能得分为47分的情况下，平均得分为23.2分，这表明约50%的问题回答错误。对饮食与疾病之间关联的了解尤其差；90%的受试者不知道高水果和蔬菜摄入量的益处。营养知识得分最高的10%的受访者与得分最低的10%的受访者相比，水果和蔬菜摄入量显著更高。
很大一部分老年人基本营养知识匮乏；这对健康饮食构成了障碍，应加以解决。
