    Purpose: Accurate estimation of the energy requirements including resting metabolic rate (RMR) is important for optimal nutritional care, yet its clinical determinants are unknown. This study examined the associations between clinical determinants of the Comprehensive Geriatric Assessment (CGA) domains with RMR among geriatric outpatients. Materials & methods: Data were retrieved from cohorts of community-dwelling older adults (n = 84, 54 female) referring to geriatrics outpatient mobility clinics in both Amsterdam, The Netherlands and Melbourne, Australia. Determinants within domains of the CGA included diseases (number, type and severity of diseases, polypharmacy), nutrition (body weight, body mass index, absolute and relative skeletal muscle mass, fat-free mass and fat mass, risk of malnutrition), physical function (handgrip strength, Short Physical Performance Battery, Timed Up & Go), cognition (Mini-Mental State Examination), psychological wellbeing (Geriatric Depression Scale) and blood pressure. RMR was objectively measured using indirect calorimetry with a canopy hood. Association between the clinical determinants with standardized RMR (country and sex-specific z-score) were analysed with linear regression adjusted for age, sex and body weight. Results: Determinants within the nutritional domain were associated with RMR; body weight showed the strongest association with RMR. Significant associations between determinants within the nutritional domain with RMR disappeared after further adjustment for body weight. None of the other domains were associated with RMR. Conclusions: Body weight is the strongest clinical determinant of RMR and should be taken into account when estimating RMR in geriatric care

    OBJECTIVE: Sarcopenia is highly prevalent in older adults. Knowledge among community-dwelling adults is important for effective prevention and treatment of sarcopenia. This study aims to assess current knowledge about sarcopenia, investigate willingness for treatment and prevention, and awareness of muscle health. METHOD: Participants who attended health educational events completed a questionnaire on knowledge about sarcopenia. Self-perceived muscle health was assessed by visual analog scale. Objective muscle measures included muscle mass, handgrip strength, and gait speed. RESULTS: Included participants were 197 (median aged 67.9 years [interquartile range = 57.0-75.1]). Eighteen participants (9%) reported to know what sarcopenia is. Participants' self-perceived muscle health showed a low correlation with all objective muscle measures. 76% were willing, in case of sarcopenia diagnosis, to start treatment and 71% were willing to prevent sarcopenia. DISCUSSION: Knowledge about sarcopenia is limited while participants were willing to start treatment and prevention. Strategies to increase knowledge among community-dwelling adults are needed

    Handgrip strength cannot be assumed a proxy for overall muscle strength

    Objectives: Dynapenia, low muscle strength, is predictive for negative health outcomes and is usually expressed as handgrip strength (HGS). Whether HGS can be a proxy for overall muscle strength and whether this depends on age and health status is controversial. This study assessed the agreement between HGS and knee extension strength (KES) in populations differing in age and health status. Design: Data were retrieved from 5 cohorts. Setting and Participants: Community, geriatric outpatient clinics, and a hospital. Five cohorts (960 individuals, 49.8% male) encompassing healthy young and older individuals, geriatric outpatients, and older individuals post hip fracture were included. Measures: HGS and KES were measured according to the protocol of each cohort. Pearson correlation was performed to analyze the association between HGS and KES, stratified by sex. HGS and KES were standardized into sex-specific z scores. The agreement between standardized HGS and standardized KES at population level and individual level were assessed by intraclass correlation coefficients (ICC) and Bland-Altman analysis. Results: Pearson correlation coefficients were low in healthy young (male: 0.36 to 0.45, female: 0.45) and healthy older individuals (male: 0.35 to 0.37, female: 0.44), and moderate in geriatric outpatients (male and female: 0.54) and older individuals post hip fracture (male: 0.44, female: 0.57) (P<.05, except for male older individuals post hip fracture [P¼.07]). Intraclass correlation coefficient values were poor to moderate in all populations (ie, healthy young individuals [0.41, 0.45], healthy older individuals [0.37, 0.41, 0.44], geriatric outpatients [0.54], and older individuals post hip fracture [0.54]). Bland-Altman analysis showed that within the same population of age and health status, agreement between HGS and KES varied on individual level

    To individualize nutritional interventions for the prevention and treatment of malnutrition and sarcopenia, it is required to understand the nutritional needs of older adults. This study explores the nutritional needs of geriatric outpatients. We hypothesized that inadequate energy and protein intake is common in geriatric outpatients. Data were retrieved from 2 cohort studies encompassing community-dwelling older adults referred to geriatric outpatient mobility clinics in Amsterdam, The Netherlands and Melbourne, Australia. Indirect calorimetry and a food diary, respectively, were used to assess resting metabolic rate (RMR) and energy and protein intake. Total energy expenditure (TEE) was calculated by the RMR multiplied by an activity factor of 1.4. An energy deficit was defined as a relative difference >10% between TEE and energy intake. A protein deficit was defined as protein intake <1.2 g/kg body weight per day. Bland-Altman analysis assessed the agreement between energy and protein requirements versus intake at an individual level. Seventy-four outpatients were included (25 males, median age 78.9 [IQR: 72.8-86.1] years). The mean difference between TEE and energy intake was 292 (SD 481) kcal/d. An energy deficit was present in 46 outpatients. The median protein intake was 1.00 (IQR: 0.87-1.19) g/kg body weight per day and a protein deficit was present in 57 outpatients. There was a low agreement between energy and protein requirements versus intake at an individual level. In conclusion, over half of the outpatients had energy and/or protein deficits. Integrating dietetic services at geriatric outpatient mobility clinics could potentially improve nutrition- and muscle-related outcomes in a multidisciplinary approach

    Background: To describe pain, cognitive function, and frailty of older people in post-acute care settings and examine the association between the three elements. Methods: This cross-sectional study involved 142 participants from a rehabilitation ward and a geriatric day centre. Pain, cognitive function and frailty were assessed using Brief Pain Inventory, Abbreviated Mental Test, and 5-item Frail Scale respectively. Results: Participants were mostly women (51.7%) with a mean age of 76.5 (SD 7.8). Mean scores for pain, cognition, and frailty were 9.0 ± 1.0, 4.0 ± 2.8, and 2.2 ± 1.2, respectively. Cognition had a significant inverse association with frailty (β = −0.160, p = 0.047), and pain had a significant positive association with frailty (β = 5.122, p < 0.001). This linear regression model explained a variance of 0.269. Conclusions: The study demonstrated the association between pain, cognitive function, and frailty. In predicting frailty, however, more studies are required to determine the predictive value and cut-off points for pain and cognitive measures

    Aim: The prevalence of chronic pain among nursing home residents with dementia is high. This present study aimed to explore the effectiveness of a play activities program among nursing home residents with dementia. Methods: Each nursing home was randomly assigned to an experimental group or control group. A 1-h play activities program was offered weekly for 8 weeks to the experimental group, whereas participants in the control group read books and magazines for 15 min weekly for the 8 weeks. Outcome measures were assessed at baseline, post-intervention (at week 8) and 4 weeks after the intervention. Results: A total of 53 nursing home residents from four nursing homes were recruited. There were significant treatment effects on pain, depression and happiness level when comparing the experimental group and control group. However, there were no treatment effects on activities of daily living, social engagement, behavioral symptoms and mobility between the two groups. Conclusion: The play activities program was useful in reducing pain and improving the psychological health of nursing home residents with dementia. Geriatr Gerontol Int 2018; 18: 1485–1490

    Play activities program to relieve chronic pain and enhance functional mobility and psychological well-being for frail older adults: a pilot cluster randomized controlled trial

    No full text
    Chronic pain is common in frail older adults. Pain can alter psychological status, causing higher levels of loneliness and depression and lower levels of happiness and life satisfaction. Pain hinders functional mobility and activities of daily living, and frail older adults consequently participate less in social activities, resulting in a deterioration of physical health and quality of life. Play activities are widely used in children, and their therapeutic effects are well established. Benefits include better communication skills, social skills, and cognitive ability.Play activities are also effective in reducing fear and anxiety for hospitalized children4 and postsurgical pain in children.5The social effects of play activities may help to reduce pain.6Older adults living in nursing homes tend to be lonelier and more socially isolated than individuals of other ages, which places them at greater risk of negative consequences of pain. The literature on play activities for older adults is scanty, but the potential beneficial effects of play activities in this age group warrant investigation. It was therefore the aim of this study to explore the therapeutic effects of play activities on the physical and psychological health of frail older adults

    Knowledge of Nutrition and Physical Activity Guidelines is Not Associated with Physical Function in Dutch Older Adults Attending a Healthy Ageing Public Engagement Event

    Purpose: Evidence-based guidelines on nutrition and physical activity are used to increase knowledge in order to promote a healthy lifestyle. However, actual knowledge of guidelines is limited and whether it is associated with health outcomes is unclear. Participants and Methods: This inception cohort study aimed to investigate the association of knowledge of nutrition and physical activity guidelines with objective measures of physical function and physical activity in community-dwelling older adults attending a public engagement event in Amsterdam, The Netherlands. Knowledge of nutrition and physical activity according to Dutch guidelines was assessed using customized questionnaires. Gait speed and handgrip strength were proxies of physical function and the Minnesota Leisure Time Physical Activity Questionnaire was used to assess physical activity in minutes/week. Linear regression analysis, stratified by gender and adjusted for age, was used to study the association between continuous and categorical knowledge scores with outcomes. Results: In 106 older adults (mean age=70.1 SD=6.6, years) who were highly educated, well-functioning, and generally healthy, there were distinct knowledge gaps in nutrition and physical activity which did not correlate with one another (R2=0.013, p=0.245). Knowledge of nutrition or physical activity guidelines was not associated with physical function or physical activity. However, before age-adjustment nutrition knowledge was positively associated with HGS in males (B= 0.64 (95% CI: 0.05, 1.22)) and having knowledge above the median was associated with faster gait speed in females (B=0.10 (95% CI: 0.01, 0.19)). Conclusion: Our findings may represent a ceiling effect of the impact knowledge has on physical function and activity in the this high performing and educated population and that there may be other determinants of behavior leading to health status such as attitude and perception to consider in future studies.peerReviewe
