目的：研究日本农村社区老年人饮食多样性下降的相关因素，以及对未来老年人营养改善计划规划的启示。设计：一项前瞻性队列研究，随访时间为1992年至2000年，为期8年。本研究在日本四个主要岛屿之一本州岛北方部分的秋田县的农村和主要农业区南盖村进行。共417名老人研究对象为1992、1994、1996、1998和2000年完成访谈和食物摄入频率调查的160名男性和257名女性。饮食多样性和可能与饮食多样性下降相关的变量是在基线和8- 10个月的面对面访谈中确定的。年的后续调查。饮食品种的测量使用的饮食品种评分（DVS），其中包括10个主要的食物组在日本mean.Results：在8年的随访中，36.2%的受试者表现出下降的饮食品种。在8年的随访中，健康特征也发生了变化，这些变化对饮食多样性的下降产生了影响。饮食多样性下降的显着预测因素包括失去配偶，自我感知的咀嚼能力恶化，智力活动score.Conclusions下降：失去配偶，咀嚼能力恶化，智力活动下降可能会增加社区居住的日本老年人的饮食多样性下降的风险。
Objective: To examine the factors related to the decline of dietary variety among the rural community-dwelling Japanese elderly people and the implication on the planning of elderly people's nutritional improvement program in the future.Design: A prospective cohort study during 8-year follow-up from 1992 to 2000.Setting: This study was conducted in Nangai Village, a rural and mainly agricultural area of Akita Prefecture in the northern part of Honshu, one of four main islands in Japan.Subjects: A total of 417 elderly people ( 160 men, 257 women) who completed interviews and food intake frequency surveys conducted in 1992, 1994, 1996, 1998, and 2000 were studied.Methods: Dietary variety and variables potentially associated with dietary variety decline were identified from a face-to-face interview at the baseline and 8-year follow-up surveys. The dietary variety was measured using the dietary variety score (DVS), which covers the 10 main food groups in Japanese meals.Results: During the 8-year follow-up, 36.2% of the subjects showed a decline in dietary variety. Health characteristics also change among the 8-year follow-up and these changes have an effect on the decline of dietary variety. Significant predictors for decline in dietary variety included loss of spouse, deterioration in self-perceived chewing ability, and decrease in intellectual activity score.Conclusions: Loss of spouse, deterioration in chewing ability, and decline in intellectual activity may increase the risk of decline in dietary variety in community-dwelling Japanese elderly people.
