The 2005 Dietary Guidelines for Americans publication placed increased emphasis on the importance of consuming a wide range of healthful foods and further reducing the consumption of less healthful ones. These recommendations are challenging for rural elders whose functional limitations, fewer resources, and limited access to foods negatively affect the quality of their diets. The purpose of this study was to characterize the diet quality of a multiethnic population-based sample of older adults (N=635) in the southern United States. Data were collected via home visit; dietary intakes were assessed using a food frequency questionnaire and converted into Healthy Eating Index-2005 (HEI-2005) scores used to monitor adherence to dietary guidelines. The mean total HEI-2005 score was 61.9/100 with fewer than 2% meeting the recommended score of 80/100. After controlling for age, sex, marital status, poverty status, and education, African Americans (n=136) had higher total HEI-2005 scores compared to American Indians (n=195) and non-Hispanic whites (n=304) (64.5 vs 60.1 and 61.1 respectively, P=0.001). Certain HEI-2005 foods were consumed in greater amounts by particular groups, such as total fruit and meat and beans (African Americans), whole fruit and grains (African Americans and American Indians), milk (non-Hispanic whites), and energy from solid fat, alcohol, and added sugars (American Indians). The overall diet quality of these rural elders was not adequate as determined by the HEI-2005; however, intakes of dark green and orange vegetables were adequate, and many participants were in compliance with the added fat and sugar guidelines. Determination of factors that promote or prevent the consumption of healthful foods among rural elders may help tailor nutrition education programs for these vulnerable communities.
《2005年美国膳食指南》出版物更加强调了食用多种健康食品的重要性,并进一步减少对健康程度较低食品的消费。这些建议对于农村老年人来说颇具挑战性,因为他们的身体机能受限、资源较少且获取食物的机会有限,这些因素会对他们的饮食质量产生负面影响。本研究的目的是描述美国南部一个以多民族为基础的老年人样本(N = 635)的饮食质量。数据通过家访收集;使用食物频率问卷评估饮食摄入量,并将其转换为用于监测对膳食指南遵守情况的2005年健康饮食指数(HEI - 2005)得分。HEI - 2005的总平均得分是61.9/100,只有不到2%的人达到推荐分数80/100。在控制了年龄、性别、婚姻状况、贫困状况和教育程度后,非裔美国人(n = 136)的HEI - 2005总得分高于美洲印第安人(n = 195)和非西班牙裔白人(n = 304)(分别为64.5、60.1和61.1,P = 0.001)。特定群体食用某些HEI - 2005食物的量更多,比如总水果、肉类和豆类(非裔美国人)、完整水果和谷物(非裔美国人和美洲印第安人)、牛奶(非西班牙裔白人),以及来自固体脂肪、酒精和添加糖的能量(美洲印第安人)。根据HEI - 2005的评估,这些农村老年人的整体饮食质量并不理想;然而,深绿色和橙色蔬菜的摄入量是足够的,并且许多参与者符合添加脂肪和糖指南。确定促进或阻碍农村老年人食用健康食品的因素可能有助于为这些弱势群体量身定制营养教育项目。
