“…Furthermore, no previous studies have examined these associations in Asian countries. Low social role is defined by decreased levels of social contact and interest and occurs with age prior to IADL decline (Ishizaki et al 2000). Because levels of social activity were inversely related to risk of functional decline (Landi et al 2004), our results suggest that people with a high level of extraversion are more likely to maintain higher-level functional capacity than those with low levels of extraversion.…”

Numerous factors that affect functional decline have been identified, and personality traits are considered to be an important factor in functional decline risk. The Tokyo Metropolitan Institute of Gerontology Index of Competence (TMIG) was developed to measure three higher-level functional capacities, instrumental activities of daily living, intellectual activity, and social roles, in Japanese elderly, which were previously not assessed adequately with existing scales of functional decline. The objective of this study was to explore the effect of personality traits as predictors of higher-level functional decline over a 7-year follow-up in a rural Japanese community. Data on 676 participants (mean 67.1 years) who were free of functional decline and had completed questionnaires at baseline and 7 years later, were analyzed. Demographic characteristics, lifestyle and personality characteristics were obtained from a self-administered questionnaire at baseline. Higher-level functional decline was examined using the subscales of the TMIG at baseline and at a 7-year follow-up examination. Over the 7-year study period, 21.7% of eligible participants reported decline in higher-level functional capacity. After adjustment for putative confounding factors, the traits that were significant predictors of decline in higher-level functional capacity at the 7-year follow-up had higher psychoticism scores [odds ratio (95% confidence interval) 2.12 (1.23-3.66)] and lower extraversion scores [1.89 (1.01-3.56)]. The personality traits of higher psychoticism and lower extraversion were significantly associated with a risk of future functional decline. A better understanding of these personality traits may help identify of at-risk individuals and could help reduce functional decline in older adults.

“…We defined IADL disability as a subject reporting that he/she could not undertake one or more IADLs. 19 We asked subjects about their dependence with respect to five BADLs: eating, dressing, toiletry, bathing, and walking on a level surface. 20,21 We defined BADL disability as a subjects reporting that he/she was dependent in one or more BADLs.…”

Older people go outdoors for various purposes, such as going shopping, taking a walk, visiting friends, and working in their garden or field. These activities are important for the maintenance of health and quality of life. With advancing age, there is a decline in the frequency of going outdoors. For example, in Japan more than 50% of older people aged 65-69 years go outside the house at least once a day, but among those aged 70-79 years and over 80 years, the respective percentages are less than 40% and 30%. 1 The clinico-epidemiologic relevance of the reduction in the frequency of going outdoors in community-dwelling older adults has not been well characterized. Getting outdoors requires a certain level of physical and mental Study PopulationThis was a two-year prospective study conducted in Yoita Town, a rural area in Niigata Prefecture, Japan. In 2000, the total population of this town was 7,493, and the proportion of older adults (i.e., 65 years and older) was 22.3%. A baseline survey was conducted in November 2000, in which all residents aged 65+ years (n=1,673) were invited to participate. Out of them, 1,544 (92.3%) persons responded to the survey. Among the 129 non-responders, 80 were institutionalized, 2 were relocated, 3 had died, and 44 refused to participate.A follow-up survey was conducted in October of 2002. Out of the initial 1,544 respondents, 1,283 (83.1%) participated again. Among the 261 non-participants, 57 were institutionalized, 12 persons were relocated, 81 persons had died, 88 refused to participate, and the remaining 23 persons did not participate for miscellaneous reasons.Trained personnel conducted standardized, face-to-face interviews with study subjects either at the community hall or in their homes, both at baseline and follow-up. The purpose of the study (collecting information on how to prevent disability among older people) was explained before interview, and all subjects participated voluntarily in accordance with a protocol approved by the Ethics Committee of Tokyo Metropolitan Institute of Gerontology. VariablesThe questionnaire comprised of sociodemographic, medical and physical function, cognitive, and psychosocial items. Sociodemographic variables included age, sex, education, principal occupation, and household structure. Medical and physical function variables included the basic activities of daily living (BADL), IADL, walking ability, visual and hearing ability, pain, chronic medical conditions, urinary incontinence, use of outpatient clinics, history of hospital admission, and frequency of going outdoors. Psychosocial variables included cognitive function, subjective health, contacts with intimate friends or relatives, participation in formal or informal community groups, and depressive mood state.In regard to the assessment of the frequency of going outdoors, subjects were asked the question, "How often do you usually go outside the house?" (Examples of going outdoors include going shopping, taking a walk, going to a hospital, or going out to work in your garden or f...

“…One explanation may be that the effect of OA on functioning is less direct than on joint pain/stiffness and inflammation. Physical functioning is affected by many additional factors, including other chronic conditions and aging (23,24). Conditions such as diabetes mellitus and cardiovascular disease can also affect functioning without being associated with joint pain, stiffness, or inflammation.…”

Predictors for Functional Decline Among Nondisabled Older Japanese Living in a Community During a 3‐Year Follow‐Up

Abstract: Having a high level hand-grip strength, good intellectual activities, and good social roles are strongly associated with remaining independence in IADL for the nondisabled Japanese persons aged > or = 65.
