“…Poor intellectual and social activities were found to be factors predicting a decline in IADL 14,15) . Thus, intellectual and social activities may have declined ahead of the onset of instrumental self-maintenance decline among our subjects, consistent with the findings of a previous study 16) . In fact, we found higher percentages in the decline of intellectual activities and social roles in both men and women compared to the declines in instrumental selfmaintenance (Table 3).…”

Abstract. [Purpose] In this study, we examined the physical predictors of the decline of functional capacity among community-dwelling older Japanese individuals.[Methods] A total of 265 Japanese individuals aged 68-96 years participated in a baseline survey and a follow-up 4 years later. In this survey, participants performed tests for grip strength, one-legged standing, and 5-m walking. At baseline and the follow-up survey, we measured functional capacity using the Tokyo Metropolitan Institute of Gerontology Index of Competence (TMIG-IC), which consists of the instrumental self-maintenance scale, the intellectual activity scale, and the social role scale. [Results] There was only a weak association between physical performance and the decline of functional status in men. The 5-m walking time was most sensitive at predicting the future decline of the instrumental self-maintenance scale in women. Even after controlling for age, body mass index, grip strength, and one-legged standing, a slower 5-m walking time (greater than 4.6 sec) indicated an increased risk of future decline in instrumental self-maintenance in women (odds ratio = 5.31, p<0.01).[Conclusions] The usual walking speed is the best performance measure for predicting the decline of instrumental self-maintenance among Japanese older women.

“…Kumagai et al (2003) pointed out that higher dietary variety is associated with a reduced risk of high-level functional capacity decline in community dwelling elderly. Moreover, according to the surveys of Fujiwara et al (2003) and Ishizaki et al (2000) based on an elderly people living in a Japanese community, maintenance of a high-level intellectual activity is strongly associated with sustaining independence in IADL. Therefore, it is also important for elderly people to maintain a lifestyle that improves intellectual activity.…”

“…In particular, Fujiwara et al (2003) reported that the intellectual activity of the elderly can be potentially modified toward a healthy direction through a correct lifestyle. Consequently, to prevent the decline of dietary variety, it is necessary to prepare a plan that improves intellectual activity in addition to the implementation of a nutritional improvement program.…”

Risk factors for dietary variety decline among Japanese elderly in a rural community: a 8-year follow-up study from TMIG-LISA

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.

Objective It is well known that depression deteriorates basic activities of daily living (ADLs), such as eating and bathing, among the elderly, but little is known about the early impact of depression symptoms on the next higher level of functioning, namely higher-levels ADLs, such as instrumental self-maintenance, intellectual activities, and social roles. The objective of this study was to determine whether symptoms of depression are associated with a subsequent decline in higher-level ADLs within a 12-month period of time. Methods The study cohort consisted of a random sample of 587 non-institutionalized adults aged C65 years living in Yamanashi prefecture, Japan. The baseline survey was conducted in 2003. After 12 months, a mailed follow-up survey evaluated changes in higher-level ADLs (follow-up rate 98.6%).Results After adjusting for sociodemographic and behavioral confounders, logistic regression indicated that baseline severe depression symptoms were associated with a 3.2-fold (95% confidence interval 1.6-6.3) higher chance of a subsequent decline in higher-level ADLs compared to those without severe depression symptoms. The presence of severe depression symptoms was selected by stepwise logistic regression in all models, except for the model with intellectual activities as an outcome, while other lifestyle factors were not selected. Conclusions Symptoms of severe depression may adversely affect higher-level ADLs even in a relatively short time-frame. In addition, the early effects of depression symptoms may be stronger than those of other traditional lifestyle risk factors. Monitoring a wide range of ADLs in elderly individuals showing signs of depression may be important to prevent a functional decline in health and the need for long-term care.
