The number and proportion of older Americans have grown rapidly in recent years, and this trend is expected to continue. Adequate nutritional intake is essential for optimal physical and mental activity. The purpose of this study was to examine the relationship of socioeconomic status and living arrangements to nutritional intake of persons 55 years of age or older living in South Carolina. Data on 268 subjects who participated in the South Carolina Nutrition Survey, which was based on a true probability sample that represents the state's adult population, were analyzed. Eighty-nine percent of the subjects were found to have poor nutritional intake on the basis of a combination of four index nutrients: iron, vitamin B-6, calcium, and vitamin A. The data did not show a relationship between living arrangements and nutrient intake but affirmed the literature findings that support a positive relationship between low socioeconomic status and inadequate nutritional intake.
近年来,美国老年人的数量和比例迅速增长,而且这一趋势预计将持续下去。充足的营养摄入对于最佳的身心活动至关重要。本研究的目的是探讨社会经济地位和生活安排与居住在南卡罗来纳州的55岁及以上人群营养摄入之间的关系。对参与南卡罗来纳州营养调查的268名受试者的数据进行了分析,该调查基于一个代表该州成年人口的真实概率样本。根据铁、维生素B-6、钙和维生素A这四种指标营养素的综合情况,发现89%的受试者营养摄入不佳。数据并未显示生活安排与营养摄入之间存在关联,但证实了文献研究结果,即低社会经济地位与营养摄入不足之间存在正相关关系。
