Thresholds of physical activities necessary for living a self-supporting life in elderly women

BACKGROUND: To decide the minimal levels (thresholds) of physical activities necessary for a self-supporting life using discriminate analysis between community-dwelling elderly individuals and daycare-service-receiving elderly individuals in Japan. METHOD: A total of twenty-six elderly women, including twelve living a self-supporting life and fourteen using a daycare service, were recruited in this study. The parameters examined were physical performance, activities of daily living, exercise capacity. Discriminate analysis was used to determine the thresholds of physical activities needed to live a self-supporting life. RESULTS: Muscle masses, grip strength, lower-extremity muscle force, gait ability and balance function in elderly individuals living a self-supporting life were significant higher than those in elderly individuals using a daycare service. A threshold of physical ability over 75% classifies accurately using the methods of discriminate analysis indicate total body muscle mass, thigh muscle mass, knee extension force, 6 min walking distance (6MD), 10 m obstacle walking time, Activity of daily living (ADL) index and daily steps. CONCLUSIONS: The present study indicates that thresholds of physical activities including gait abilities, muscle force, and muscle mass are very important factors in maintaining a self-supporting life for elderly individuals. Thresholds of physical activities were more effective than standard values of physical activity for elderly individuals using a care service in meeting the goals of rehabilitation.     

Mobility in the community-dwelling elderly and its correlates

OBJECTIVE: To examine mobility level in community-dwelling elderly using a questionnaire of walking ability over a distance of 1 km and its relationship to activities of daily living (ADL) and quality of life (QOL) indices, and to obtain clues to mobility impairment in the elderly. SUBJECTS AND METHODS: A total of 3,266 community-dwelling elderly aged 60 to 84 years were interviewed with questionnaires for assessing mobility, ADL and QOL levels. The mobility was assessed by walking ability over a distance of 1 km, and the ADL levels were by conventional basic ADL, comprehensive mobility index and the Tokyo Metropolitan Institute of Gerontology Index of Competence, and the QOL levels were by self-rated health, Geriatric Depression Scale (GDS) short-version and Life Satisfaction Index-K (LSIK). They were also asked about diseases for which they regularly consult doctors, and about subjective symptoms. RESULTS: Eighty-seven percent of the subjects responded to the interview, with 86.3% of male responders and 77.6% of female responders answering that they could walk on foot over a distance of 1 km without any difficulty. The percentages of subjects who answered that they could walk but with difficulty or could not walk over a distance of 1 km increased with advancing age. The correlation analysis between 1 km-walking ability and other mobility indices showed that 1 km-walking ability was a better index for identifying a slight to moderate mobility impairment, and that the mobility level was closely associated with daily activity levels in the community-dwelling elderly. The elderly with an impaired mobility had lowered self-rated health, GDS and LSIK scores. After controlling for sex and age, it was shown that prevalences of musculoskeltal (knee arthritis, lower back pain, etc.), cerebrovascular and heart diseases, and complaints of subjective symptoms which were associated with physical frailty, were closely associated with impaired mobility. Hearing and visual disturbances also had a significant relation to a lowered mobility. CONCLUSIONS: Walking ability over a distance of 1 km may be a good index for discriminating differing mobility levels which community-dwelling elderly have intrinsically. The possible etiological factors for a lowered mobility in the elderly include musculoskeletal, cerebrovascular and heart diseases; physical frailty; and hearing and visual disturbances.     

Nutritional Status of Functionally Dependent and Nonfunctionally Dependent Elderly in Taiwan

Objective: The purpose of this study was to measure and compare nutritional status of the functionally dependent elderly with those nonfunctionally dependent elderly by assessing nutrient intake, anthropometric measurements, hematological and biochemical parameters, and the nutritional risk index (NRI).

Methods: Ninety-six volunteers (42 functionally dependent elderly, 54 nonfunctionally dependent elderly) participated in this study. The items of activity of daily living (ADL) were assessed to determine functional status. Demographic and health data were collected at the time of interview. Subjects completed 24-hour diet recall and food frequency questionnaires. Height, weight and skinfold thickness measurements were taken. Hematological and biochemical parameters were measured. The NRI was then calculated.

Results: Osteoporosis and hypertension were the most frequently reported chronic diseases. A small proportion of the elderly with functional dependence (9.5%) and with nonfunctional dependence (13%) had a body mass index (BMI) (≤21 kg/m²), indicating they were underweight. There were no significant differences in nutrient intake between the two groups. However, a higher percentage of the functionally dependent elderly had a nutrient intake of less than 75% of the Taiwan Recommended Daily Nutrient Allowance (RDNA). The functionally dependent group had a higher prevalence of malnutrition than the nonfunctionally dependent group (44.7% vs. 25%) based on the NRI.

Conclusions: These functionally dependent elderly people exhibited a poorer nutritional status than the nonfunctionally dependent elderly. The elderly with functional dependence were at risk for inadequate iron intake and abnormal serum triglyceride concentrations; they were also at greater risk for chronic diseases and had a greater need for medications.     

Functional and Nutritional State in Elderly Men With Compensated Hypogonadism

ObjectivesThere are few data investigating the relationship between compensated hypogonadism and functional and nutritional status of elderly individuals. Impairment of functional and nutritional status of elderly men with compensated hypogonadism needs to be investigated. In this study, we tried to evaluate the association of functional and nutritional status with testosterone and LH levels in elderly with compensated hypogonadism.DesignA cross-sectional study was performed.SettingA total of 1124 patients older than 70 years were screened.ParticipantsA total of 250 patients (patient group) with compensated hypogonadism and 250 subjects (control group) with normal hormone levels were allocated in the study.MeasurementsAll parameters were compared in patient and control groups. The correlations between hormone levels and activities of daily living (ADL), instrumental activities of daily living (IADL), Mini Mental State Examination (MMSE), Mini Nutritional Assessment (MNA), and Geriatric Depression Scale (GDS) were evaluated.ResultsADL, IADL, MMSE, and MNA scores were significantly lower in the patient group. Testosterone and LH levels were correlated with ADL (R = 0.221 and R = ?0.262), IADL (R = 0.210 and R = ?0.277), MMSE (R = 0.331 and R = ?0.341), MNA (R = 0.211 and R = ?0.297), and GDS (R = ?0.214 and R = ?0.211) in the patient group independently from age and body mass index.ConclusionsOur study showed that geriatric men with compensated hypogonadism had worse functionality, cognitive function, nutritional status, and mood compared with healthy controls.     

Ankle-brachial pressure index and mini nutritional assessment in community-dwelling elderly people

Background

A low ankle-brachial pressure index (an ABPI value <0.90) is considered predictive of cardiovascular disease, and is widely thought to increase morbidity and mortality in the elderly. However, good nutrition is beneficial both for the health and the ability to resist and recover from the disease.

Objective

The aim of the present study was to evaluate the relationship between the ankle-brachial pressure index and the nutritional status of the elderly in a city of Kochi prefecture, Japan.

Methods

This was a cross-sectional study in which a total of 100 elderly people, both males and females, were screened for ankle-brachial pressure index (ABPI), nutritional status (through the use of the short form of the mini nutritional assessment), activities of daily living, lifestyle, gait speed (10MWT), postural stability (OLST), and functional mobility (TUg).

Results

About 67% of the participants were found to have a normal nutritional status, 27% were at risk of malnutrition, and six percent were classified as malnourished. The mean ABPI of the participants was 1.08±0.10, and three participants had an ABPI lower than 0.90. The ABPI was statistically higher in well nourished participants compared with those at risk of malnutrition or the malnourished. The mean ABPI was significantly higher in non-smokers compared with former smokers. The ABPI was found to correlate negatively with gait speed and with TUg score.

Conclusion

Well-nourished elderly had a higher normal ankle-brachial pressure index as compared with the malnourished elderly. This study provides supportive evidence for the necessity of adequate nutrition for elderly people.     

A Nutritional Status Survey of Older Adults in Long-Term Care in the Yazd Province of Iran

It is important to assess the nutritional status of older adults because of its role in ensuring health and quality of life and its association with functional status. The purpose of this study was to evaluate the nutritional status of an older adult population living in long-term care institutions in the Yazd province of Iran. Fifty elderly subjects were randomly selected from each of two long-term care institutions in Yazd. A 3-day food intake survey was conducted using the direct weighing method and anthropometric measurements for calculating body mass index (BMI) were also collected. Of the participants, 54% of women and 41% of men had a BMI less than 19.9 kg/m². The mean intakes of energy, protein, vitamins A and C, riboflavin, and niacin as well as the minerals calcium, phosphorus, and iron, were significantly less than Dietary Reference Intakes (DRIs) for both genders. Thiamin intake was more than adequate in both women and men. In our study, the majority of elderly subjects displayed a poor reported nutritional intake according to the DRIs. Our findings support the development of national nutrition plans for older adults living in long-term care institutions as an important necessity.     

Health status, lifestyle and nutrient intake of home resident elderly in Bahrain

The elderly are more susceptible to chronic diseases which reduce functional capacity. Researches on health and nutritional status, therefore, are needed to prevent and control these chronic diseases. The objective of this study was to find out the health, lifestyle, ability to carry out daily living tasks, and intake of nutrients among home-resident Bahraini elderly. Data were based on a cross-sectional community study of 201 Bahraini elderly aged 65 years, which were selected proportionally from all geographical regions of Bahrain (88 men and 113 women). They were visited and interviewed at home by trained female workers, using a pre-tested questionnaire. There was no statistically significant difference between men and women in the history of chronic diseases. However, the proportion of chronic diseases was higher among women, except for peptic ulcer. Men were more likely to smoke (38.6%) than women (24.8%) (p = 0.0353). Dietary supplements were more common among men (19.3%) than women (12.4%). Mean nutrient intakes for energy, iron and calcium were below the USA Recommended Daily Allowances. Men had more capability to do daily activities without help than women. In conclusion, there is a need to establish a national plan of action to promote health and nutritional status among the elderly of Bahrain. This study can provide some baseline data for further in depth study of health status of Bahraini elderly.     

Comparing survey data on functional disability: the impact of some methodological differences.

STUDY OBJECTIVE: To examine the impact of some differences in survey methodology on the prevalence of functional disability in population based surveys of the elderly. DESIGN AND METHODS: Nine surveys of Dutch people aged 55 years and older were compared to investigate the differences in the methods of data collection (proxy questioning, yes/no; interview versus self administered questionnaire) and construction of the questionnaire (wording of introductory text, activities, and response categories). The effect of these differences on prevalences in three domains of functional disability--activities of daily living, mobility, and communication--were studied. Both univariate analyses and multivariate logistic regression were used to quantify the methodological influences. RESULTS: No effect of proxy questioning could be shown. Self administered questionnaires yielded higher prevalences of disability than interviewer administered questionnaire--in particular for mobility (odds ratio (OR) 1.4, 95% confidence interval (95% CI) 1.3, 1.6) and communication (OR = 1.7, 95% CI 1.5, 1.9), resulting in prevalence differences of 9 and 11 percentage points respectively. Seemingly minor differences in the structure and wording of the questionnaires resulted in major differences (up to 15.6 percentage points) in prevalence estimates of functional disability. These differences were associated with the severity level of the disability indicated by the wording of the questions. CONCLUSIONS: Differences in survey methodology have a substantial effect on the prevalence estimates of disability in the elderly. These differences should be taken into account when making international comparisons and studying time trends based on survey data.

Health profile of the elderly in Brazil: analysis of the 2003 National Household Sample Survey using the Grade of Membership method

The aim of this study was to identify functional disability and health profiles of the elderly in Brazil, as well as their prevalence rates, based on the National Household Sample Survey for 2003. The sample size was 33,786 elderly individuals. Grade of Membership was used to define the profiles: "healthy elderly" (Profile 1), whose pure types had a lower probability of disability and chronic illness; "elderly with mild functional disability" (Profile 2), whose pure types had mainly hypertension and lower back problems and were independent in activities of daily living, although with high difficulty in mobility; and "elderly with severe disability" (Profile 3), with higher probability of chronic illness, high difficulty with activities of daily living, and high dependency in terms of mobility. In conclusion, the profiles indicate that a consistent approach to functional disability is essential for promoting the health of the elderly.     

Role of weight history on functional limitations and disability in late adulthood: the ARIC study

OBJECTIVE: To examine associations of weight history with functional limitations and disability in white and African-American men and women. RESEARCH METHODS AND PROCEDURES: Data were from the Atherosclerosis Risk in Communities study (n = 11,177). Associations of recalled weight status at age 25 and weight change from age 25 to ages 45 to 64 with functional limitations, activities of daily living (ADLs), and instrumental activities of daily living (IADLs) at follow-up (ages 52 to 75) were examined using logistic regression. RESULTS: Obesity (BMI > or = 30 kg/m2) at age 25 was associated with functional limitations and ADL and IADL impairment at follow-up in white and African-American men and women. For example, obese compared with normal weight (BMI, 18.5 to 24.9 kg/m(2)) white women had higher odds of mild [odds ratio (95% confidence interval), 1.97 (1.18 to 3.29)] and severe [9.81 (5.92 to 16.27)] functional limitations and ADL [3.48 (2.36 to 5.13)] and IADL [2.95 (2.00 to 4.33)] impairment. In African-American women, obesity was associated with higher odds of mild [2.71 (1.14 to 6.41)] and severe [6.01 (2.53 to 14.26)] functional limitations and ADL [1.82 (1.10 to 3.00)] and IADL [2.39 (1.47 to 3.90)] impairment. Similar associations were found in men. Compared with weight maintenance (+/-10 lbs), large weight gain (>30 lbs) from age 25 to ages 45 to 64 was also associated with functional limitations and ADL and IADL impairment in white and African-American men and women. DISCUSSION: Maintenance of a healthy body weight throughout adulthood may play a role in preventing or delaying the onset of functional limitations and disability, resulting in increased quality of life and decreased health care costs.     

Body mass index and measures of adiposity among elderly adults

OBJECTIVE: To evaluate the nutritional status of elderly persons and to compare the correlation between the body mass index (BMI=kg/m2) with measures of adiposity and fat distribution among elderly and middle-aged adults. METHODS: Elderly persons (N=699; 60 years or older) and middle-aged adults (N=1,306; 40-59.9 years) participating in a population-based survey conducted in 1996 in the municipality of Rio de Janeiro were evaluated as to body mass index, arm, waist, and hip circumferences, skinfolds, and arm fat and muscle areas using standardized procedures. The cutoff points proposed by the World Health Organization for waist circumference, waist-to-hip ratio, and body mass index were used. Analyses were performed using the Spearman correlation coefficient and linear regression adjusted for age. RESULTS: About 50% of elderly subjects were classified as overweight and more than 50% of women in all age groups had waist circumference and waist-to-hip ratio outside the normal range. Among men, these percentages were about 40% for waist circumference and 20% for waist-to-hip ratio. Among elderly subjects, the partial correlation (adjusted for age) between body mass index and measures of adiposity (waist circumference, skinfolds, and arm fat area) ranged from 0.45 to 0.85 for men and 0.55 to 0.86 for women. Weight and waist circumference were the variables more strongly correlated with body mass index among both elderly persons and adults. CONCLUSIONS: The prevalence of overweight among elderly persons was high for both men and women. Body mass index shows a similar relationship with adiposity regardless of ageing.     

Sarcopenia according to the European Working Group on Sarcopenia in older people (EWGSOP) versus dynapenia as a risk factor for disability in the elderly

Background

Sarcopenia, defined as low muscle mass (LMM), and dynapenia have been associated with adverse outcomes in elderly.

Objective

Contrast the association of sarcopenia versus dynapenia with incidence of disability.

Design p]A four-year prospective study (2006–2010)

Setting

São Paulo, Brazil.

Participants

478 individuals aged 60 and older from the Saúde, Bem-Estar e Envelhecimento (SABE) study who were non-disabled at baseline.

Measurements

Sarcopenia, measured according to the European Working Group on Sarcopenia in Older People (EWGSOP), includes: LMM assessed by skeletal muscle mass index ≤8.90kg/m2 (men) and ≤6.37kg/m2 (women); low muscle strength (LMS) assessed by handgrip strength <30kg (men) and <20kg (women); and low physical performance (LPP) assessed by gait speed ≤0.8m/s. Diagnosis of sarcopenia required LMM plus LMS or LPP. Dynapenia was defined as handgrip strength <30kg (men) and <20kg (women). Covariates included socio-demographic and behavioral variables, medical conditions, hospitalization, depressive symptoms, cognition, perception of vision, hearing and body mass index.

Outcomes

Disability in mobility or instrumental activities of daily living (IADL) or disability in activities of daily living (ADL) and IADL.

Results

The incidence density of mobility or IADL disability was 43.4/1000 person/year and 22.6/1000 person/year for IADL and ADL disability. There was no significant difference in incidence density according sarcopenia or dynapenia status. After controlling for all covariates, sarcopenia was associated with mobility or IADL disability (relative risk ratio = 2.23, 95%Confidence Interval: 1.03–4.85). Dynapenia was not associated with disability.

Conclusions

Sarcopenia according to the EWGSOP definition can be used in clinical practice as a screening tool for early functional decline (mobility or IADL disability).     

The effect of nutritional intervention in elderly subjects residing in group-living for the demented

OBJECTIVES: We studied the nutritional status and the effects of nutritional intervention on body weight, cognition and activities of daily life (ADL)-function in demented individuals. DESIGN: Controlled non-randomised study. SETTING: Group-living for demented elderly (GLD), ie community assisted housing. SUBJECTS AND INTERVENTIONS: Twenty-two residents living in one of two units (GLD-I), received oral liquid supplements (1720 kJ/410 kcal/day) and the personnel of the GLD-I were given nutritional education. Fourteen residents in the other unit (GLD-C) served as controls. After 6 months 21 (83 (4) y, 81% women) and 12 (85 (4) y, 100% women) of the participants, respectively, were re-examined according to body mass index (BMI, kg/m2), cognitive function (Mini Mental State Examination (MMSE, 0-30 p) and Clinical Dementia Rating Scale (CDR) and the Katz' ADL index. RESULTS: Body mass index (BMI) < or =20 was found in 19% of the participants and 44% had BMI< or =23. BMI correlated with MMSE (r=0.43, P<0.01). The weight of the residents in the intervention group increased by 3.4 (3) kg (P=0.001) at follow-up, whereas the weight remained unchanged in the control group. The cognitive function was low at the start in both groups, ie MMSE approximately 9 and no apparent positive effect of the nutritional intervention was seen. In addition, the ADL functions appeared to deteriorate in both groups. CONCLUSIONS: Being underweight was common among demented elderly in group-living and was related to low cognitive capacity. Five months of oral supplementation, along with education of personnel, was followed by a weight gain. In this study the nutritional treatment did not affect the rate of decline in cognitive function or Katz' ADL index.

Prevalence of functional limitations among adults 60 years of age and over: United States, 1999-2002

In the 1999-2002 National Health and Nutrition Examination Survey (NHANES), participants were asked a series of questions designed to evaluate functional status. Some questions assessed performance on selected activities of daily living (ADLs) and instrumental activities of daily living (IADLs), while others assessed mobility, strength, endurance, and social participation. This report contains prevalence estimates and standard errors for adults, 60 years of age and over, who reported difficulty performing these activities without the aid of special equipment or who were not able to perform these activities. Results are reported by sex, age group, race and ethnicity, and body mass index (BMI). Assessment of functional status plays an important role in monitoring the health problems and needs of older Americans.     

Low staffing level is associated with malnutrition in long-term residential care homes

OBJECTIVE: To determine if staffing level is associated with poor nutrition in the long-term residential care setting, adjusting for other confounding factors. DESIGN: Cross-sectional survey. SETTING: In total, 14 residential care facilities in Hong Kong, stratified by nature (government subvention or for-profit) to reflect the overall proportion in Hong Kong. SUBJECTS: A total of 1914 subjects were assessed, using the Resident Assessment Instrument (RAI) 2.0. The response rate was 95% (1820 subjects), of which 1699 subjects had complete nutritional information. INTERVENTION: Body mass index (BMI) was calculated by weighing and height measurement, and arm span was used if the subject could not stand. Subjects who were receiving parenteral or enteral nutrition via nasogastric of enterostomy tubes were excluded. A history of weight loss of 5% in the past month or 10% in the past 6 months, leaving 25% of food uneaten, and BMI < 18.5 kg/m(2) were examined as nutritional indicators. Association with age, gender, functional disability, oral problems, taste problems, presence of physical diseases and psychological well-being was examined using chi(2)-test, and multiple logistic regression. RESULTS: In all, 26% of residents had a BMI < 18.5 kg/m(2), with a higher prevalence in the for-profit homes. History of weight loss and the record that 25% of food was left uneaten were poor indicators of low BMI. Multivariate analysis showed that having chronic obstructive airways disease, requiring help with feeding, being female, older age, were factors associated with an increased risk of poor nutrition, while being independent in activities of daily living and higher staff levels were associated with a reduced risk. CONCLUSION: Poor nutrition is a persistent problem in the long-term care setting, and inadequate staffing levels may be a reversible cause. However, resource limitations may render efforts at improvement difficult. SPONSORSHIP: SK Yee Memorial Fund.     

Nutritional status of Saudi males living in the Riyadh nursing home

This study evaluated the nutritional status of residents in the Riyadh nursing home, using anthropometric and haematological measurements. All male residents (N=84; age range 24-80 years) in the Riyadh nursing home were included in the study. Weight, height, body mass index, triceps skin fold thickness, and mid-arm muscle circumference were measured. Furthermore, serum concentrations of albumin, haemoglobin and haematocrit were measured. About 13% of adult residents and 11% of elderly residents were considered to be underweight (body mass index <18.5 kg/m(2)). From estimations of fat mass in the periphery, using triceps skin fold thickness, it appears that the elderly residents had significantly lower fat mass compared to the adult residents (P <0.05). The results showed that more than 40% of residents had low mid-arm muscle circumference (<22.3 cm). Serum albumin concentration was significantly lower in the elderly group than in the adult group (P<0.01). No significant difference was found in haematocrit level between the adult and elderly residents. Within the adult group, about 38% of residents had low haemoglobin level (<12 mg/dl), and this proportion was even higher, about 55%, in elderly residents. Based on body mass index or albumin to determine the prevalence of malnutrition among residents, the results have shown that the prevalence of undernourished residents was not higher than the prevalence of undernourished nursing-home residents reported in other studies. The percentage of elderly residents with anaemia was appreciable. Thus, undernourished and anemic residents should have special dietary and medical attention. Early detection of malnutrition upon admission would lead to early intervention and thus to reduced complications and medical-treatment costs. Staff working in nursing homes should be aware of the nutritional guidelines for health and disease.
