Associations between living arrangements and several eating behaviors were examined for 4,402 adults aged 55 and older using three-day food intake data from the 1977-78 Nationwide Food Consumption Survey (NFCS). Compared to those living with a spouse, persons living alone ate more meals alone and consumed a higher proportion of total calories away from home; a higher proportion of those living alone skipped meals, including breakfast. There was a sex differential in the effect of living alone for some, but not all, of the eating behaviors. Both the probability of eating away from home and of skipping breakfast declined with age, as did the percentage of calories consumed from snacks. These results indicate a need to focus further research not only on the effects these eating behaviors have on the nutritional status of elderly persons, but also on middle-aged cohorts as they age and on food programs targeted at elderly persons living alone.
利用1977 - 1978年全国食物消费调查(NFCS)的三日食物摄入数据,对4402名55岁及以上的成年人的居住安排与几种饮食行为之间的关联进行了研究。与与配偶同住的人相比,独居的人独自用餐的次数更多,在外就餐所摄入的总热量比例更高;独居者中有更高比例的人不吃正餐,包括不吃早餐。在某些但并非所有饮食行为方面,独居的影响存在性别差异。在外就餐的概率和不吃早餐的概率均随年龄增长而下降,零食所提供热量的百分比也是如此。这些结果表明,不仅需要进一步研究这些饮食行为对老年人营养状况的影响,还需要研究中年人群随着年龄增长的情况以及针对独居老年人的食物项目。
