Depression, activities of daily living, and quality of life of community-dwelling elderly in three Asian countries: Indonesia, Vietnam, and Japan.

The purpose of this study was to examine the prevalence of screening-based depression and the association of depression with activities of daily living (ADL) and quality of life (QOL) of community-dwelling elderly in the developing and developed countries. A total of 2,695 community-dwelling elderly subjects aged 60 years or older living in five rural Asian towns (Indonesia: 411, Vietnam: 379, Japan: 1,905) participated in this cross-sectional study. Depressive symptoms were assessed using a 15-item geriatric depression scale (GDS-15). ADL, higher daily activities, and medical and social history were assessed by interviews or self-report questionnaires. For the assessment of subjective QOL, a 100mm visual analogue scale was used. Using a cut-point of 5/6 for the GDS-15, 782 participants (29.0%) appeared to have depression (Indonesia: 33.8%, Vietnam: 17.2%, Japan: 30.3%). Subjects with depression had significantly lower scores for both ADL and QOL than those without depression in all the three countries. In all the three countries, 17.2-33.8% of community-dwelling elderly subjects had screening-based depression, which was commonly associated with both lower quantitative ADL and lower QOL.

High morning home blood pressure is associated with a loss of functional independence in the community-dwelling elderly aged 75 years or older.

To elucidate the relationship between home systolic blood pressure (SBP) and functional impairment in the elderly 75 years or older, 461 community-dwelling subjects (192 men, 269 women, mean age: 80 years) were studied. Home blood pressure was measured twice in the morning and twice in the evening for 5 consecutive days with an automatic cuff-oscillometric device. Total/high-density lipoprotein cholesterol and several functional assessments were evaluated. A subject was determined to exhibit a loss of independence according to the activities of daily living (ADL) score in a study conducted in 2001. Based on the mean home SBPs (mSBP) and morning-evening SBP differences (dSBP), the subjects were classified into 4 groups as follows: hypertensive/morning-dominant (HM; mSBP > or = 135 mmHg, dSBP > or = 15 mmHg), hypertensive/sustained (HS; mSBP > or = 135 mmHg, dSBP<15 mmHg), normotensive/morning-dominant (NM; mSBP<135 mmHg, dSBP > or = 15 mmHg), and normotensive/controlled (NC; mSBP<135 mmHg, dSBP<15 mmHg). There were no differences in sex, cholesterol levels, history of stroke, other cardiovascular diseases (CVDs), and cognitive function, but there were significant differences in age, antihypertensive medications, the neurobehavioral test scores, and ADL scores. There were no significant differences in terms of mortality and CVD events. In the survivors, HM and HS were independent risk factors for a loss of independence, after adjustments were made for onset of stroke, age, antihypertensive therapy, history of CVD, as well as neurobehavioral test scores and ADL scores (odds ratio [OR]: 12.2 and 3.78, respectively). After the same adjustments as those mentioned above were made, HM and HS were found to be negative determinants of survival and maintenance of independence (OR: 0.082, 0.270, respectively). In conclusion, high home SBP (> or = 135 mmHg) and high dSBP (> or = 15 mmHg) were found to be important in determining the levels of disability for the very elderly.

Knee pain in people aged 80 years and older is not associated with gait parameter and functional performance.

We evaluated the differences in gait and functional performance between two groups of elderly people, one consisting of people between 65 and 79 years of age and the other consisting of people over 80 years of age. We analysed whether knee pain affected gait and looked at the functional performance of the timed 'up and go' (TUG) and functional reach (FR) tests. In 247 community-dwelling people aged 65 years and older, consisting of 90 men and 157 women with a mean age of 80 years (range 65-94 years), 47% had knee pain. Shorter stride, shorter step, slower speed, longer TUG and shorter FR were seen in the group aged 80 years and over compared with the group aged 65-79 years. Knee pain was associated with TUG, especially in the group aged 65-79 years. In the group aged 65-79 years with knee pain, a shorter stride and step length, a longer time required to hold a double stance, a slower walking speed and a longer TUG were shown. However, in the group aged 80 years and over, there was no significant difference between participants with and without knee pain for these parameters.

Depression in Japanese community-dwelling elderly--prevalence and association with ADL and QOL.

This cross-sectional study examined the prevalence of screening-based depression and compared the scores of activities of daily living (ADL) and quality of life (QOL) between community-dwelling elderly subjects with and without depression in Japan. Elderly subjects aged 65 or older living in four rural towns participated in 2000 or 2001 (n = 5363, female 58.3%, mean (S.D.) age 74.6 (7.0) years). Depressive symptoms were assessed using a 15-item Geriatric Depression Scale (GDS-15) and ADL, higher functions, and medical and social histories were assessed by self-report questionnaires. For assessing subjective QOL, a 100 mm visual analogue scale was used. One thousand seven hundred ninety-eight participants (33.5%, range, 32.3-34.6%) had suggestive depression using cutoff 5/6 of GDS-15. Subjects with depression revealed significantly lower scores for ADL and QOL than those without depression. Prevalence of screening-based depression was similar in the four different rural Japanese towns. However, the reported prevalence of depression varies enormously in different country. Primary physicians and caregivers should pay more attention to depression in the community-dwelling elderly population, especially below the threshold of major depression as minor depression or dysthymia.
