BackgroundPeople with intellectual disabilities (ID) have a lower life expectancy than their peers without ID. A contributing factor to the lower life expectancy and early mortality could be sarcopenia: low muscle mass and low muscle function. In the general population, sarcopenia strongly predicts early mortality, but this association is unknown in people with ID. Therefore, this study aims to explore the association between sarcopenia and 5-year mortality in older adults with ID.MethodsIn the Healthy Ageing and Intellectual Disabilities (HA-ID) study, the prevalence of sarcopenia was measured at baseline among 884 older adults (≥50 years) with ID. All-cause mortality was measured over a 5-year follow-up period. Univariable and multivariable Cox proportional hazard models were applied to determine the association between sarcopenia (no sarcopenia, pre-sarcopenia, sarcopenia, severe sarcopenia) and early mortality, adjusted for age, sex, level of ID, presence of Down syndrome, and co-morbidity (chronic obstructive pulmonary disease, diabetes type 2 and metabolic syndrome).ResultsThe unadjusted hazard ratio (HR) for sarcopenia was 2.28 [95% confidence interval (CI) 1.48–3.42], P < 0.001), and 2.40 (95% CI 1.40–4.10, P = 0.001) for severe sarcopenia. When adjusted for age, sex, level of ID, and Down syndrome, sarcopenia (HR = 1.72, 95% CI 1.08–2.75, P = 0.022) and severe sarcopenia (HR = 1.86, 95% CI 1.07–3.23, P = 0.028) were significantly associated with early mortality. When additionally adjusted for co-morbidity, the adjusted HR decreased to 1.62 (95% CI 1.02–2.59, P = 0.043) and 1.81 (95% CI 1.04–3.15, P = 0.035) for sarcopenia and severe sarcopenia, respectively.ConclusionSarcopenia is an independent risk factor for early mortality in older adults with ID over a 5-year follow-up period. Our results stress the need to delay the incidence and development of sarcopenia in older adults with ID.
Objective: To examine the prevalence of sarcopenia and its association with protein intake in men and women in a multi-ethnic population. Design: We used cross-sectional data from the HELIUS (Healthy Life in an Urban Setting) study, which includes nearly 25,000 participants (aged 18–70 years) of Dutch, South-Asian Surinamese, African Surinamese, Turkish, Moroccan, and Ghanaian ethnic origin. For the current study, we included 5161 individuals aged 55 years and older. Sarcopenia was defined according to the EWGSOP2. In a subsample (N = 1371), protein intake was measured using ethnic-specific Food Frequency Questionnaires. Descriptive analyses were performed to study sarcopenia prevalence across ethnic groups in men and women, and logistic regression analyses were used to study associations between protein intake and sarcopenia. Results: Sarcopenia prevalence was found to be sex- and ethnic-specific, varying from 29.8% in Turkish to 61.3% in South-Asian Surinamese men and ranging from 2.4% in Turkish up to 30.5% in South-Asian Surinamese women. Higher protein intake was associated with a 4% lower odds of sarcopenia in the subsample (OR = 0.96, 95%-CI: 0.92–0.99) and across ethnic groups, being only significant in the South-Asian Surinamese group. Conclusion: Ethnic differences in the prevalence of sarcopenia and its association with protein intake suggest the need to target specific ethnic groups for prevention or treatment of sarcopenia.
PURPOSE: Malnutrition and sarcopenia require dietetic and physiotherapy interventions. In this study, we aimed to compare interprofessional identity of dietitians and physiotherapists, as well as attitudes towards, facilitators and barriers for, and occurrence of interprofessional treatment of malnutrition and sarcopenia by both professions.METHODS: A cross-sectional online survey was distributed from December 4, 2021 until January 31, 2022 through an international online network platform for professionals (LinkedIn). Practitioners working as dietitian or physiotherapist in a healthcare setting were eligible for participation. Outcome measures concerned perceptions regarding shared problem domains, interprofessional treatment, attitudes towards interprofessional treatment, interprofessional identity, facilitators, and barriers. A Chi 2-test, Mann-Whitney U-test, and Spearman's Rho correlation were calculated. RESULTS: Data from 53 physiotherapists and 48 dietitians were included. Malnutrition is considered a shared problem domain by both professions ( U = 1248.000; p = 0.858). While sarcopenia is treated by both professions ( U = 1260.000; p = 0.927), physiotherapists consider sarcopenia more often a shared problem domain compared to dietitians ( U = 1003.000; p = 0.044). Attitudes towards interprofessional treatment were mostly positive (73%, n = 35 and 87%, n = 46 respectively). Interprofessional identity of dietitians was lower compared to physiotherapists (median = 4.0 versus median = 4.3 respectively; U = 875.000, p = 0.007). This was explained by lower interprofessional belonging (median = 4.0 versus median = 4.8 respectively; U = 771.000, p < 0.001) and lower interprofessional commitment (median = 4.0 versus median = 4.3 respectively; U = 942.500, p = 0.023). Interprofessional identity was correlated with efficient means of communication ( r = 0.30, p = 0.003) and bureaucracy ( r = -0.21, p = 0.034). Other barriers reported included available time, financial compensation, interprofessional knowledge, and obtaining extra care. Most reported facilitators concerned role clarity, clarity of expertise, and willingness of others to collaborate. CONCLUSION: Dietitians and physiotherapists have different interprofessional identities, but both are advocates of interprofessional treatment. Both professions mostly treat malnutrition and sarcopenia individually and have different perceptions regarding sarcopenia as shared problem domain. Facilitators were mainly related to clarity and commitment while barriers were mainly related to resources.
De samenwerking tussen de onderzoeksgroep FRIA van de Vrije Universiteit Brussel, afdeling oudergeneeskunde van het UMCG Groningen en de onderzoeksgroep (lectoraat) Healthy Ageing, Allied health Care and Nursing van de Hanzehogeschool Groningen is gericht op onderzoek naar bewegingsstoornissen bij veroudering. In het bijzonder wordt gekeken naar paratonic, een bewegingsstoornis bij dementie.The International Joint Research group ‘Move in Age’ concluded in a systematic review that paratonia still is a barely understood and devastating phenomenon in dementia and revealed the urgency of gaining more insight in the pathophysiology. Paratonia, a distinctive change in muscle tone, starts in early stages of dementia and develops further with progress of the disease. Resulting in severe discomfort for patients, but also affecting caregivers since daily care becomes increasingly difficult. It is hypothesized that changes in motor control due to dementia influences peripheral neurological control and biomechanical muscle structures (by crosslinking and inflammation caused by advanced glycation end-products (AGEs).This IJRG started in 2018 and aims to develop a long-term comprehensive research program on movement-related impairments at higher age. The three partners have a strong track record on research in the area of movement-related impairments in older persons; however, each focusing on a specific aspect. In fact, the Frailty in Ageing research group (FRIA) of the Vrije Universiteit Brussel (VUB) is running focused research program on the triad sarcopenia-dynapenia-inflammation with mainly a bio-gerontological and bio-psycho-medical approach; the department of General Practice and Elderly Care Medicine of the University Medical Center Groningen (UMCG) has anongoing research line on the medical aspects of mobility impairments in frail elderly persons and in elderly dementia patients; and finally Research Group Healthy Ageing, Allied Health Care and Nursing of the Hanze University of Applied Sciences Groningen (HUAS) developed a research program on physical, psycho-cognitive and social dimensions of frailty including the functional impact of mobility impairments. In the first 3-5 years, the focus will be on the movement-related impairments that occur in patients with dementia and in specific on paranoia. The programme will be extended towards movement-related impairments in the context of other geriatric syndromes.
