Is the Effect of a High-Intensity Functional Exercise Program on Functional Balance Influenced by Applicability and Motivation among Older People with Dementia in Nursing Homes?

BACKGROUND AND OBJECTIVES: Exercise can be an important way of maintaining balance function in people with dementia, but further investigation is needed to determine the optimal way of exercising. The objective was to evaluate whether exercise applicability (i.e., attendance, exercise intensity, and adverse events) and motivation were associated with the effect on functional balance of a high-intensity functional exercise program for older people with dementia in nursing homes. DESIGN, SETTING AND PARTICIPANTS: Exercise intervention participants (n = 81; 60 women, 21 men) from a randomized controlled trial (UMDEX) were included. Their mean age was 84 and mean Mini-Mental State Examination score was 15. INTERVENTION: Groups of 3-8 participants participated in the High-Intensity Functional Exercise (HIFE) Program, with 5 sessions per 2-week period, for 4 months (total, 40 sessions). MEASUREMENTS: Outcome was the Berg Balance Scale (BBS), assessed at baseline and follow up, and the score difference, dichotomized to classify participants into two groups: responders (≥5-point increase) and non-responders (<5-point increase). Target variables were measures of applicability and motivation. Associations between each target variable and the outcome were analyzed using multivariable logistic regression. Baseline characteristics and new medical conditions developing during the intervention period were compared between responders and non-responders and included in the analyses when p < 0.10. RESULTS: The BBS score was 28.6 ± 14.3 at baseline and 31.2 ± 15.3 at follow up, with the difference between follow-up and baseline scores ranging from -35 to 24. Twenty-nine (35.8%) participants were responders. The multivariable models showed no significant association between responders vs. non-responders and any target variable. CONCLUSION: Participation in a 4-month high-intensity functional exercise program can improve balance in many individuals with dementia in nursing homes, despite the progressiveness of dementia disorders and several co-existing medical conditions. Predicting balance exercise response based on applicability and motivation seem not to be possible, which lends no support for excluding this group from functional exercise, even when exercise intensity or motivation is not high.

A comprehensive fracture prevention strategy in older adults: the European Union Geriatric Medicine Society (EUGMS) statement.

Prevention of fragility fractures in older people has become a public health priority, although the most appropriate and cost-effective strategy remains unclear. In the present statement, the Interest Group on Falls and Fracture Prevention of the European Union Geriatric Medicine Society, in collaboration with the International Association of Gerontology and Geriatrics for the European Region, the European Union of Medical Specialists, and the International Osteoporosis Foundation-European Society for Clinical and Economic Aspects of Osteoporosis and Osteoarthritis, outlines its views on the main points in the current debate in relation to the primary and secondary prevention of falls, the diagnosis and treatment of bone fragility, and the place of combined falls and fracture liaison services for fracture prevention in older people.

Risk factors for hip fracture in very old people: a population-based study.

SUMMARY: Knowledge of risk factors for hip fracture among very old people is limited. Walking indoors with help from ≤1 person, Parkinson's disease, currently smoking, delirium in the previous month, underweight, and age were associated with increased risk of hip fracture and could be important for preventive strategy development. INTRODUCTION: The purpose of this study is to investigate risk factors for hip fracture among a representative sample of very old people. METHODS: In total, 953 participants from the Umeå 85+/Gerontological Regional Database population-based cohort study were interviewed and assessed during home visits. Associations of baseline characteristics with hip fracture during the maximum 5-year follow-up period were analyzed using Cox proportional hazards regression. RESULTS: Participants had a mean age of 89.3 ± 4.7 years; 65.8% were women, 36.8% lived in residential care facilities, 33.6% had dementia, and 20.4% had histories of hip fracture. During a mean follow-up period of 2.7 years, 96 (10.1%) individuals sustained hip fracture. Walking indoors with help from no more than one person (hazard ratio [HR] = 8.57; 95% confidence interval [CI], 1.90-38.71), Parkinson's disease (HR = 5.12; 95% CI, 1.82-14.44), currently smoking (HR = 4.38; 95% CI 2.06-9.33), delirium in the previous month (HR = 2.01; 95% CI, 1.15-3.49), underweight (body mass index <22; HR = 1.74, 95% CI, 1.09-2.77), and age (HR = 1.09; 95% CI, 1.04-1.14) were associated independently with an increased risk of hip fracture. Hip prosthesis at baseline decreased the risk of hip fracture (HR = 0.37; 95% CI, 0.15-0.91), but only for those with bilateral hip prostheses. CONCLUSIONS: Seven factors were associated independently with incident hip fracture during follow-up in this sample of very old people. These factors could have important clinical implications in identifying persons at high risk of hip fracture, as well as in the development of effective preventive strategies.

Perceptions of participating in high-intensity functional exercise among older people dependent in activities of daily living (ADL).

The purpose of the study was to evaluate how older people, dependent in ADL perceive their participation in a high-intensity, functional exercise program compared to the perceptions of those participating in a control activity. Forty-eight older people living in residential care facilities answered a questionnaire about their perceptions of participating in an activity for three months. They were aged 65-98, had a mean score of 24 on Mini Mental State Examination (MMSE) and 14 on Barthel ADL Index. The participants had been randomized to exercise (n=20) or control activity (n=28). Differences in responses between exercise and control activity were evaluated using logistic and ordinal regression analyses. The results show that a majority of the exercise group perceived positive changes in lower limb strength, balance, and in the ability to move more safely and securely compared to a minority of the control group (p<0.001). Significantly more respondents in the exercise activity answered that they felt less tired due to the activity (p=0.027) and that they prioritized this activity above other activities (p=0.010). More exercise participants reported that meeting for three months was too short, and fewer that it was too long compared to the control group (p=0.038). This study shows that older people living in residential care facilities, dependent in ADL, and with mild or no cognitive impairment had positive perceptions about participating in high-intensity functional exercise. The findings support the use of a high-intensity exercise program in this population of older people.

Poor nutritional status is associated with urinary tract infection among older people living in residential care facilities.

AIM: To investigate factors associated with poor nutritional status in older people living in residential care facilities. METHODS: 188 residents (136 women, 52 men) with physical and cognitive impairments participated. Mean age was 84.7 y (range 65-100). The Mini Nutritional Assessment (MNA), Barthel ADL Index, Mini Mental State Examination (MMSE), and Geriatric Depression Scale were used to evaluate nutritional status, activities of daily living, cognitive status and depressive symptoms. Medical conditions, clinical characteristics and prescribed drugs were recorded. Univariate and multivariate regressions were used to investigate associations with MNA scores. RESULTS: The mean MNA score was 20.5 ± 3.7 (range 5.5-27) and the median was 21 (interquartile range (IQR) 18.8-23.0). Fifteen per cent of participants were classified as malnourished and 66% at risk of malnutrition. Lower MNA scores were independently associated with urinary tract infection (UTI) during the preceding year (ß = - 0.21, P = 0.006), lower MMSE scores (ß = 0.16, P = 0.030), and dependent in feeding (ß = - 0.14, P = 0.040). CONCLUSION: The majority of participants were at risk of or suffering from malnutrition. Urinary tract infection during the preceding year was independently associated with poor nutritional status. Dependence in feeding was also associated with poor nutritional status as were low MMSE scores for women. Prospective observations and randomized controlled trials are necessary to gain an understanding of a causal association between malnutrition and UTI.

Effects of high-intensity exercise and protein supplement on muscle mass in ADL dependent older people with and without malnutrition: a randomized controlled trial.

BACKGROUND: Loss of muscle mass is common among old people living in institutions but trials that evaluate interventions aimed at increasing the muscle mass are lacking. Objective, participants and intervention: This randomized controlled trial was performed to evaluate the effect of a high-intensity functional exercise program and a timed protein-enriched drink on muscle mass in 177 people aged 65 to 99 with severe physical or cognitive impairments, and living in residential care facilities. DESIGN: Three-month high-intensity exercise was compared with a control activity and a protein-enriched drink was compared with a placebo drink. A bioelectrical impedance spectrometer (BIS) was used in the evaluation. The amount of muscle mass and body weight (BW) were followed-up at three and six months and analyzed in a 2 x 2 factorial ANCOVA, using the intention to treat principle, and controlling for baseline values. RESULTS: At 3-month follow-up there were no differences in muscle mass and BW between the exercise and the control group or between the protein and the placebo group. No interaction effects were seen between the exercise and nutritional intervention. Long-term negative effects on muscle mass and BW was seen in the exercise group at the 6-month follow-up. CONCLUSION: A three month high-intensity functional exercise program did not increase the amount of muscle mass and an intake of a protein-enriched drink immediately after the exercise did not induce any additional effect on muscle mass. There were negative long-term effects on muscle mass and BW, indicating that it is probably necessary to compensate for an increased energy demand when offering a high-intensity exercise program.

Recovery in geriatric depression.

BACKGROUND: Clinical characteristics of depression, age at illness onset, medical burden, disability, cognitive impairment, lack of social support, and poor living conditions may influence the course of depression. This study investigates the timetable of recovery and the role of the above factors in predicting recovery in elderly patients with major depression. METHODS: Recovery was studied in 63 elderly (age >63 years) and 23 younger patients with depression who were followed up for an average of 18.2 months (SD, 13.1 months) under naturalistic treatment conditions. Diagnosis was assigned according to Research Diagnostic Criteria after administration of the Schedule for Affective Disorders and Schizophrenia. The Longitudinal Follow-up Interval Examination was used to identify recovery. RESULTS: The recovery rate of depressed elderly patients was similar to that of younger depressed patients. In the elderly patients, age, antidepressant treatment, age at onset, and chronicity of episode were significantly associated with time to recovery since entry. Among these parameters, late age at onset was the strongest predictor of slow recovery. In younger patients, long time to recovery was predicted by weak social support, younger age, cognitive impairment, and low intensity of antidepressant treatment. In the elderly, the intensity of antidepressant treatment began to decline within 16 weeks from entry and approximately 10 weeks prior to recovery. CONCLUSIONS: These findings challenge the view that geriatric depression has a worse outcome than depression in younger adults. However, depressed patients with onset of first episode in late life may be at higher risk for chronicity. Antidepressant treatment prescribed by clinicians may decline prior to recovery despite evidence that high treatment intensity is effective in preventing relapse.

Personality disorder correlates of late and early onset depression.

OBJECTIVE: To compare the lifetime personality dysfunction of geriatric patients having late and early onset of major depression. DESIGN: Group comparisons. SETTING: Inpatient geriatric psychiatry unit and hospital-based geriatric psychiatry outpatient clinic. PATIENTS: Volunteer sample of recovered elderly depressives with history of early onset of major depression (age < 60) (n = 16) and history of late onset of major depression (age > 60) (n = 14). MAJOR OUTCOME MEASURE: Personality Disorder Examination, containing diagnostic and dimensional scores for DSM-III-R personality disorders. RESULTS: The two groups had similar demographic profiles and levels of depression after treatment. Early onset subjects had significantly higher mean dimensional scores in the avoidant, dependent, and not otherwise specified NOS personality disorders, and higher dimensional scores with a trend toward significance in 6 additional personality disorders. CONCLUSIONS: Early onset geriatric depressives may have more lifetime personality dysfunction than late onset subjects. Greater personality dysfunction in early onset subjects may reflect postdepressive changes, predisposition, or a low grade depressive subtype.

Factors associated with weight control in older adults.

Dieting behaviors in a sample of 183 overweight older adults were studied to assess how they were influenced by six cognitive, behavioral, emotional, and social variables. Membership in a weight control program was also evaluated to assess whether it affected these relationships. Responses indicated that reports of high quality dieting behaviors were associated with higher levels of depression and less effective coping skills. Dieting behaviors among subjects who were participants in weight loss programs were not as strongly associated with less effective coping skills, but were associated with external health locus-of-control. The degree of social support had a limited impact on dieting behaviors, while measures of optimism and health status were unrelated to dieting behaviors. We concluded that older adults, especially those who diet independently, are likely to experience significant stress associated with weight loss efforts. Weight loss programs for older adults might produce better outcomes if they focus on reducing depression and stress associated with dieting.
