Socioeconomic Disadvantage is Associated with Probable Sarcopenia in Community-Dwelling Older Adults: Findings from the English Longitudinal Study of Ageing.

BACKGROUND: Sarcopenia is characterized by the accelerated loss of muscle strength, mass, and function in aging. The disease is a major public health issue with emerging evidence of a disproportionate burden in areas of socioeconomic disadvantage. OBJECTIVES: To estimate the prevalence of probable sarcopenia overall, and according to Socioeconomic Position (SEP). To explore the association between markers of SEP and probable sarcopenia. DESIGN: Cross-sectional analysis of the English Longitudinal Study of Ageing data. SETTING: England, United Kingdom (UK). PARTICIPANTS: This study comprised 6,052 older adult participants from Wave 6 of the English Longitudinal Study of Ageing (ELSA) aged 60 years and older. MEASUREMENTS: Probable sarcopenia was identified by the EWGSOP2 guidelines as low hand grip strength (females <16kg and males <27kg) or poor chair rise test performance (completion of 5 chair rises >15 seconds). Socioeconomic position was defined by educational attainment and subjective social status (SSS). Weighted multivariable regression analysis was employed to identify determinants of probable sarcopenia. RESULTS: Over one-third of older adults met the criteria for probable sarcopenia (33.7%; weighted, 36.1%) in the study population of mean age 70.7 (SD 7.7) years. When examined by SEP, the prevalence of probable sarcopenia was over 2-fold higher in adults in the most vs the least disadvantaged SEP groups (47.0% vs 20.6%, respectively, p<0.001). Multivariable regression analysis identified disadvantaged SEP, as measured by educational attainment and SSS, as independent predictors of probable sarcopenia, along with older age, physical inactivity, underweight BMI, chronic conditions, osteoarthritis, and minority group ethnicity. CONCLUSIONS: Disadvantaged SEP was associated with an increased likelihood of probable sarcopenia when controlled for other known risk factors. The findings suggest a need and opportunity for sarcopenia prevention and treatment strategies to address socioeconomic disadvantage in policies and practice.

High prevalence of dementia among community dwelling older adults in receipt of state funded home care packages: implications for health care planning.

OBJECTIVES: The majority of people living with dementia in Ireland reside in their own homes, some supported by formal or informal home care. This audit aimed to estimate the prevalence of dementia and suspected cognitive impairment (CI) among older adults, 65+ years, in receipt of formal home care (domiciliary care) in a defined health service area in North Dublin. A secondary objective of the audit was to explore factors associated with dementia or CI in this cohort. METHODS: A cross-sectional audit was conducted on all clients aged 65+ years actively receiving publicly funded home care packages (HCPs) during May 2016 in Healthcare Service Executive CHO9 Dublin North Central. A total of 935 urban community dwelling older adults were included in the study [mean age 83.7 (s.d. 7.4) years and 65% female]. Basic socio-demographic and health data were extracted from common summary assessment reports. Service users were categorised as having (a) dementia if a diagnosis of dementia or cognitive decline which impacts on independent living, was documented by a health professional or (b) suspected CI where a validated cognitive screening tool was applied and the score was indicative of mild CI. RESULTS: Overall, the estimated prevalence of dementia and suspected CI was 37.1% and 8.7%, respectively. Factors significantly associated with dementia and suspected CI were higher dependency and home care hours, communication difficulty and being non-self-caring (p<0.001). Notably, half (51.6%) of those with either dementia or suspected CI group lived alone. CONCLUSIONS: Our findings suggest a high prevalence dementia among HCP users, highlighting a need and opportunity for dementia-specific approaches to support older people in their homes.
