RESUMEN

The emergence of sex robots raises important issues about what it means to be human and the commodification of love, companionship, and sex. This commentary discusses the following question: If some members of society relate to robots as "humans," what does this mean for society's conceptualisation of personhood and intimate relationships? How love is expressed between individuals is normally considered a very private expression of companionship that should remain in the private sphere. This article examines whether sex robots should be subject to public regulation given the broader societal impacts of their ability to emotionally connect and elicit empathy from humans.

RESUMEN

OBJECTIVE: To identify factors that predict admission to long-term care (LTC) and mortality among community-based, dependent older people in Ireland, who were in receipt of formal home support. METHODS: An audit was conducted of all community-dwelling older adults receiving government funded home support during 2017 in the Dublin North Central, Health Service Executive administrative area. Data were extracted from the Common Summary Assessment Report (CSAR), a mandatory form used in the provision of home support. Multiple logistic regression analysis was used to examine the factors associated with admission to LTC and mortality, with the results presented as odds ratios (OR) and 95% confidence intervals. RESULTS: The audit comprised 1597 community-dwelling older adults with a mean age of 83.3 (SD: 7.2) years. The prevalence of transition to LTC and mortality was 8% and 9%, respectively, during the 12-month period. Factors significantly associated with admission to LTC were "cognitive dysfunction" [OR 2.10 (1.41-3.14), P < .001] and the intensity of home support [OR 1.05 (1.01-1.06), P < .003], as measured by weekly formal care hours. Physical dependency and advanced age (aged 95 years +) were significantly associated with mortality in this population (P < .001). CONCLUSION: "Cognitive dysfunction" and intensity of formal home support were associated with transition to LTC, while physical dependency and advanced age were associated with mortality. Investment in personalised, cognitive-specific, services and supports are necessary to keep people with dementia and related cognitive impairments living at home for longer.

RESUMEN

BACKGROUND: There is increasing demand for formal government funded home help services to support community-dwelling older people in Ireland, yet limited information exists on the health profiles of this group, especially regarding frailty. Our aim was to profile a large cohort of adults in receipt of low level home help and to determine the prevalence of frailty. METHODS: A total 1312 older adults, (≥ 65 years) in receipt of low level home help (< 5 h per week) were reviewed by community nurses and frailty was assessed using the Clinical Frailty Scale (CFS) in this cross-sectional study. Characteristics of the group were compared between males and females and prevalence of frailty was reported according to gender and principal care. Associations between frailty and a number of variables were explored using bivariate and regression analysis. RESULTS: The cohort of low level home-help users was a mean age of 82.1 (SD 7.3) years, predominantly female (70.6%) and over half (69.2%) lived alone. The prevalence of frailty in this population was 41.5%, with subjects primarily considered mildly (23.2%) or moderately frail (14.5%) by the CFS. A further 38.4% were classed as vulnerable. The degree of frailty did not differ significantly across the younger categories aged 65-84 years. However, in the oldest age groups, namely 90-94 and >95 years, moderate frailty was significantly higher relative to the younger groups (21% and 34%, p < 0.05, p < 0.01 respectively). Home help hours significantly correlated with frailty (rs = 0.371, p < 0.001) and functional dependency (rs = 0.609, p < 0.001), but only weakly with age (rs = 0.101, p = 0.034). Based on regression analysis, determinants of frailty included greater dependency (Barthel score), higher home help hours, non-self-caring and communication difficulty, all of which significantly contributed to the model, with a r squared value of 0.508. CONCLUSION: A high prevalence of frailty (41.5%) was documented in this population which associated with higher home help utilisation. Frailty was associated with greater functional dependency, but not strongly with chronological age, until after 90 years. These findings highlight opportunities for developing intervention strategies targeted at ageing in place among home help users.

RESUMEN

BACKGROUND: Vitamin D, as potential immune modulator, has been implicated as an environmental risk factor for Crohn's disease (CD). Vitamin D status may be associated with disease risk, severity, activity, and progression. While associations between circulating 25OHD and markers of disease activity and inflammation in CD have been reported, the results are inconsistent. AIM: To determine the association between vitamin D status and markers of disease activity and inflammation in CD. METHODS: One hundred and nineteen CD patients' active and inactive diseases were enrolled in the cross-sectional study. Subject demographics and clinical data were collected. A serum sample was collected for 25OHD and CRP analysis, and a stool sample was collected for fecal calprotectin (FC) measurement. RESULTS: The mean serum 25OHD concentration of the group was 59.8 (24.9) nmol/L. After controlling for confounding variables, serum 25OHD inversely correlated with FC (r = -0.207, P = 0.030), particularly among those in clinical remission (r = -0.242, P = 0.022). The association between FC and 25OHD was further confirmed by linear regression (r = 31.3 %, P < 0.001). FC was lower in patients with 25OHD levels ≥75 nmol/L compared with levels <25 nmol/L [FC: 32.2 (16.3-98.2) vs 100.0 (34.4-213.5) µg/g, P = 0.004]. In the current study, however, 25OHD was not significantly associated with either CRP or CDAI. CONCLUSION: Circulating 25OHD was significantly inversely associated with intestinal inflammation as determined by FC in CD. Subgroup analysis confirmed the association among those in clinical remission, but not in those with active disease. 25OHD was not associated with disease activity score (CDAI) or systemic inflammation (CRP). Vitamin D intervention studies are warranted to determine whether raising serum 25OHD levels in patients with CD may reduce intestinal inflammation as measured by FC.

RESUMEN

OBJECTIVE: Identify the impact of COVID-19 lockdown restrictions on the vitamin D status of individuals in the west of Ireland. DESIGN: Cross-sectional study. SETTING: Adults who had wintertime serum 25(OH)D analysis completed in Galway University Hospital. PARTICIPANTS: A total of 16,725 participants (2015-2020 (n = 13,449) and 2020-2021 (n = 3276)). Baseline demographics; sex, age, origin of the sample and the date of sample collection. RESULTS: Median serum vitamin D and serum vitamin D3 concentrations were higher in the 5-month period from October-February 2020-2021 (61 nmol/L (± 36-85 nmol/L) and 60 nmol/L (± 34-85 nmol/L)) respectively, than for the corresponding 5-month period (October-February) in 2015-2020 (53 nmol/L (± 32-78 nmol/L) and 51 nmol/L (± 30-77 nmol/L)) respectively. These changes coincided with a decline in the prevalence of deficiency. In the 5-month period October-February 2020-2021, 19.2% of the population were vitamin D deficient (< 30 nmol/L) compared to 22.5% in the corresponding 5-month period in 2015-2020, and 38.1% were vitamin D deficient (< 50 nmol/L) in the 5-month period October-February 2020-2021 compared to 46.6% in the corresponding 5-month period in 2015-2020. Males were more likely to be deficient at both thresholds (p < 0.001). For the total cohort, at the < 30 nmol/L threshold, inpatients (25.5%) and nursing home residents (34.1%) had higher prevalence of deficiency. CONCLUSIONS: Vitamin D levels were higher in the 5-month period of October-February 2020-2021, and this precipitated a decline in deficiency at both thresholds, indicating that lockdown coincided with enhanced vitamin D status. We postulate that it may be attributable to changes in diet and/or supplementation, or increased sun exposure, but further confirmatory studies are required.

RESUMEN

OBJECTIVES: The objective of this study was to investigate how mast cell tryptase may influence intestinal permeability and tight junction (TJ) proteins in vitro and explore translation to irritable bowel syndrome (IBS). METHODS: We investigated the effect of: (1) tryptase on Caco-2 monolayers, (2) mast cell degranulation in a Caco-2/human mast cell-1 (HMC-1) co-culture model, (3) mast cell degranulation±tryptase inhibition with nafamostat mesilate (NM). Epithelial integrity was assessed by transepithelial resistance (TER), permeability to fluorescein isothiocyanate (FITC)-dextran and transmission electron microscopy (TEM). The expression of junctional proteins zonula occludens-1 (ZO-1), junctional adhesion molecule-A (JAM-A), claudin-1 (CLD-1), CLD-2, CLD-3, occludin and E-cadherin was determined by western blot analysis and immunofluorescence confocal microscopy. Based on the in vitro results, we further assessed JAM-A expression in biopsy tissue (cecum) from 34 IBS patients, 12 controls, and 8 inflammatory controls using immunofluorescence confocal microscopy and explored associations between JAM-A and IBS symptoms. RESULTS: ptase disrupted epithelial integrity in Caco-2 monolayers as shown by a significant decrease in TER, an increase in permeability to FITC-dextran, and a decrease in the expression of junctional proteins JAM-A, CLD-1, and ZO-1 within 24 h. Correspondingly, in the Caco-2/HMC-1 co-culture model we showed a significant decrease in TER, an increase in permeability to FITC-dextran, and the presence of open TJs (TEM) in response to mast cell degranulation within 24 h. In this co-culture model, mast cell degranulation significantly decreased JAM-A and CLD-1 protein expression at 24 h. Tryptase inhibition (NM) significantly reduced the effect of mast cell degranulation on the junctional protein JAM-A, TER, and FITC-dextran flux. In IBS, epithelial JAM-A protein expression was significantly reduced in IBS tissue compared with controls. Lower JAM-A expression was associated with more severe abdominal pain (rs=-0.69, P=0.018) and longer duration of symptoms (rs=-0.7, P=0.012) in IBS-alternating subtype. CONCLUSIONS: uced JAM-A expression in vitro appears to contribute to the underlying mechanisms of altered epithelial integrity in response to tryptase released from degranulating mast cells. In IBS, JAM-A expression was significantly reduced in the cecal epithelium and associated with abdominal pain severity. JAM-A may provide new insights into the underlying mechanisms in IBS.

RESUMEN

(1) Background/Objectives: The relationship between body mass index (BMI) and probable sarcopenia, a precursor to sarcopenia diagnosis, is unclear. While low BMI has been associated with sarcopenia risk, some evidence suggests that obesity may confer protection. We aimed to investigate the association between probable sarcopenia and BMI and, furthermore, to explore associations with waist circumference (WC). (2) Methods: This cross-sectional study included 5783 community-dwelling adults (mean age 70.4 ± 7.5 years) from Wave 6 of the English Longitudinal Study of Ageing (ELSA). Probable sarcopenia was defined using the European Working Group on Sarcopenia in Older People (EWGSOP2) criteria for low hand grip strength and/or slow chair rise. Associations between BMI and probable sarcopenia were examined using multivariable regression analysis and were similarly performed for WC. (3) Results: Our overall findings show that an underweight BMI was significantly associated with an increased likelihood of probable sarcopenia [OR (CI) 2.25 (1.17, 4.33), p = 0.015]. For higher BMI categories, the findings were conflicting. Overweight and obesity were associated with an increased likelihood of probable sarcopenia when defined by lower limb strength alone, [OR (CI), 2.32 (1.15, 4.70), p = 0.019; 1.23 (1.02, 1.49), p = 0.35, and 1.49 (1.21, 1.83), p < 0.001, respectively]. In contrast, overweight and obesity appeared protective when probable sarcopenia was assessed by low hand grip strength alone [OR (CI) 0.72 (0.60, 0.88), p = 0.001, and 0.64 (0.52, 0.79), p < 0.001, respectively]. WC was not significantly associated with probable sarcopenia on multivariable regression analysis. (4) Conclusion: This study supports the evidence that low BMI is associated with an increased likelihood of probable sarcopenia, highlighting an important at-risk group. The findings for overweight and obesity were inconsistent and may be measurement dependent. It seems prudent that all older adults at risk of probable sarcopenia, including those with overweight/obesity, are assessed to prevent underdetection of probable sarcopenia alone or with the double burden of obesity.

RESUMEN

BACKGROUND: Adults of advanced age, with functional dependency, socioeconomic disadvantage, or a need for home care, are expected to be at high risk of sarcopenia, frailty and malnutrition, yet are likely to be underrepresented in research. We aimed to explore the assessment of sarcopenia, frailty, and malnutrition in-home, and to describe the practicality of performing these assessments. METHODS: Home-based health assessments and post-study feedback surveys were conducted among community-dwelling older adults ≥65 years in receipt of state-funded home care (n = 31). Assessments included probable sarcopenia [hand-grip strength (HGS), chair rise-test, and SARC-F case-finding tool], the Mini Nutritional Assessment (MNA), and the Clinical Frailty Scale (CFS). RESULTS: The study group was of mean age 83.2 ± 8.2 years, 74% were female and 23% lived in socioeconomically disadvantaged areas. Almost all met the criteria for probable sarcopenia (94%, n = 29/31), were frail or vulnerable by the CFS (97%, n = 30/31), and over a quarter were at risk of malnutrition (26%, n = 8). Participants had low physical activity (71.0%, n = 22/31), with a mean daytime average of 11.4 ± 1.6 h spent sitting. It was possible to assess probable sarcopenia (by HGS and SARC-F, but not the chair rise test), malnutrition (MNA), and frailty (CFS). Home-based research was a complex environment, and unearthed significant unmet need, prompting referrals to health services (36%, n = 11), in addition to technology assistance. The majority of participants (93%) reported a willingness to partake in future research. CONCLUSIONS: Most community-dwelling older people in receipt of home support, assessed in this exploratory study, were at risk of probable sarcopenia, frailty, and low physical activity, with over a quarter were at risk of malnutrition. Our initial findings provide practical data for large scale studies and may inform the development of intervention studies aiming to support ageing in place.

RESUMEN

Introduction: Socioeconomic disadvantage is associated with multiple adverse health outcomes in ageing. Whether this negative impact persists in populations of more advanced age and dependency is less clear. We aimed to determine the association between residential area deprivation and pre-specified health characteristics among community-dwelling dependent older adults. Methods: We conducted a cross-sectional analysis of data from 1591 community-dwelling adults aged 65 years and older of mean age 83.9 ± 7.1 years and in receipt of state home support in Ireland. The HP Pobal Deprivation Index was used to categorize residential areas by socioeconomic deprivation. Health variables analysed included physical dependency (Barthel Index), polypharmacy (≥5 medications), previous acute hospital admission, cognitive impairment, and mental health diagnoses. Associations between residential area deprivation and prespecified health outcomes were explored in multivariable logistic regression analysis. Results: In socioeconomically disadvantaged areas, high physical dependency was twice that observed in affluent areas (16.2% vs 6.9%, p = 0.009). Similarly, acute hospitalization, as the trigger for increased dependency, was more common in deprived settings (41.6% v 29.1%, p < 0.001). Polypharmacy was common in this population (67.6%), but significantly higher in deprived vs affluent settings (74.7% v 64.5%, p = 0.030). The findings persisted in multivariable analyses when adjusted for age and gender. While all participants were accessing home support, those in deprived areas were on average 6.5 years younger than in affluent areas. Associations between residential deprivation and mental health conditions or cognitive impairment, however, were not observed in this study. Conclusion: Community-dwelling older adults living in socioeconomically disadvantaged areas experienced greater polypharmacy, high physical dependency, hospitalization-associated dependency, and a 6.5-year earlier need for state home support than in affluent settings. The findings suggest that health inequality persists in populations of more advanced age and dependency and highlight a need for further research as well as community-based health and social care initiatives.

RESUMEN

Purpose: Physical activity has been shown to improve older adults' functional capacity, independence, and quality of life. In a feasibility study, we embedded a movement approach within older adults existing home care services through "Care to Move" (CTM). The aim of this qualitative study is to explore older adults' experiences of CTM within their home care support services and to identify the strengths and barriers of engaging in CTM from the perspective of the older recipient. Materials and Methods: We conducted semi-structured telephone interviews with 13 older adults and one informal carer. Topics covered included participants' overall experiences of CTM, changes to their overall activity and participation, aspects of CTM that they found valuable and issues that were challenging. Interview transcripts were coded and analyzed thematically to capture barriers and facilitators to the approach delivery. Results: Four themes were developed: i) "I have good days and bad days", ii) "safety and security is the name of the game", iii) "we're a team as it stands', iv) "it's [COVID-19] depressing for everybody at the moment". Older adults identified benefits of CTM engagement including improvements in physical and psychological wellbeing. However, subjective frailty and self-reported multimorbidity influenced overall engagement. Participants expressed concerns around the logistics of delivering CTM and competing care staff interests. The broader role of care staff in supporting CTM was highlighted, as well as the emotional support that staff provided to older adults. Care staff continuity was identified as a barrier to ongoing engagement. The impact of COVID-19 on older adults physical and mental health negatively impacted the delivery of the approach. Conclusion: Our findings suggest that embedding CTM within home care services is feasible and that older adults enjoyed engaging in CTM. Addressing care staff continuity and adopting individual approaches to CTM delivery may enhance the implementation of services.

RESUMEN

Introduction: In Ireland, over 55,000 older adults are supported in their community by formal home support, amounting to an estimated 23 million care hours annually. There is a growing need to move beyond care, to more proactive approaches to maintain physical function. In a feasibility study, we delivered the "Care to Move" (CTM) program through existing home support services. This qualitative study aimed to explore the experience and perceptions of Health Care Assistants (HCAs), who were trained in and delivered the CTM program. Methods: We conducted semi-structured telephone interviews with 22 HCAs [mean age 49.0 ± 10.7 years and female 21/22] involved in the delivery of the program with older adults [n = 35, mean age 82.8 (7.8) years]. Interview transcripts were coded and analyzed thematically to capture barriers and enablers to program delivery. Results: Barriers and enablers were identified under three themes i) the CTM approach ii) the home support setting, iii) older adults and physical activity, with iv) delivering care in a crisis and v) future directions further identified. Overall, there was a positive perception of the program's focus on "movement prompts and motivators", the "fit" within home support services, and the training provided. Practical challenges of limited time and the task-orientated nature of home support were reported as recurring barriers for CTM. Many HCAs commented on the value and perceived positive benefits of the program for their clients. Though negative perceptions of older adults' motivation or ability to engage with physical activity were noted. Risk, such as injury or pain, was identified but was not a dominant theme. Conclusion: Our findings suggest that embedding physical activity initiatives within home support services could be feasible. Restructuring of services, engaging HCAs, and moving beyond traditional "task-oriented" care models to more personalised proactive approaches may facilitate this initiative and support aging in place.

RESUMEN

Background: Care to Move (CTM) provides a series of consistent 'movement prompts' to embed into existing movements of daily living. We explored the feasibility of incorporating CTM approaches in home care settings. Methods: Feasibility study of the CTM approach in older adults receiving home care. Recruitment, retention and attrition (three time points), adherence, costs to deliver and data loss analyzed and differentiated pre and post the COVID-19 pandemic. Secondary outcomes, including functional status, physical activity, balance confidence, quality of life, cost to implement CTM. Results: Fifty-five home care clients (69.6% of eligible sample) participated. Twenty were unable to start due to COVID-19 disruptions and health issues, leaving 35 clients recruited, mostly women (85.7%), mean age 82.8 years. COVID-19 disruption impacted on the study, there was 60% retention to T2 assessments (8-weeks) and 13 of 35 (37.1%) completed T3 assessments (6-months). There were improvements with small to medium effect sizes in quality of life, physical function, balance confidence and self-efficacy. Managers were supportive of the roll-out of CTM. The implementation cost was estimated at EUR 280 per carer and annual running costs at EUR 75 per carer. Conclusion: Embedding CTM within home support services is acceptable and feasible. Data gathered can power a definitive trial.

RESUMEN

OBJECTIVE: There is growing evidence that vitamin D may have immunomodulatory properties in Crohn's disease (CD). The aim of this study was to determine if serum 25-hydroxy-vitamin D [25(OH)D] was associated with inflammatory cytokines, IL-10, and TNF-alpha levels in patients with inactive CD. METHODS: This was a prospective study of 75 adults with quiescent CD. Serum 25(OH)D was measured by radioimmunoassay and serum IL-10 and TNF-alpha by ELISA. Disease activity was assessed by the Crohn's disease activity index (CDAI) and C-reactive protein (CRP). RESULTS: IL-10 levels were significantly lower in patients with vitamin D insufficiency compared with the vitamin D replete group (mean and SE 2.48 ± 0.51 v 6.77 ± 2.49 pg/mL, p < 0.001). There were, however, no differences in serum TNF-alpha or CRP levels based on vitamin D status. The use of a vitamin D supplement at a low dose (200 IU) did not significantly influence IL-10 levels. CONCLUSION: Circulating levels of IL-10, but not TNF-alpha, were significantly lower in CD patients with inadequate serum 25(OH)D. This suggests that poor vitamin D status may be linked to reduced anti-inflammatory capacity in this group.

RESUMEN

INTRODUCTION: Maintaining skeletal muscle function throughout life is a crucial component of successful aging. Disadvantaged socioeconomic position (SEP) is associated with adverse health outcomes, but has not been extensively studied for the muscle disease sarcopenia. We aimed to determine the prevalence of probable sarcopenia, a precursor to sarcopenia diagnosis, based on the European Working Group on Sarcopenia in Older People 2 (EWGSOP2) guidelines overall, and according to SEP. METHODS: This cross-sectional study comprised 3342 community-dwelling older adults [mean age (SD) 68.9 ± 6.3 years] from Wave 1 of the Irish Longitudinal Study on Ageing. Probable sarcopenia was identified using gender-specific cut-off values for handgrip strength as recommended by EWGSOP2. SEP was defined by educational attainment. Multivariate regression analysis was employed to determine associations between probable sarcopenia and pre-defined risk factors. RESULTS: Overall, 23.4% of the population had probable sarcopenia and was significantly higher in the subset with low compared with high SEP (28.9% vs 18.1%, p<0.001). Consistent with this, multivariate logistic regression analysis showed that disadvantaged SEP was a significant determinant of probable sarcopenia [OR, CI 1.48 (1.17, 1.87) p<0.001]. Other known risk factors, namely, increased age, low physical activity, comorbidity, and osteoarthritis were significantly associated with an increased likelihood of probable sarcopenia, while overweight/obesity appeared to be protective. CONCLUSION: Disadvantaged SEP was an independent determinant of probable sarcopenia in community-dwelling older adults. These findings highlight that SEP and health inequality should be considered in prevention and treatment policy for sarcopenia in the community.

RESUMEN

At northern latitudes, non-ethnic population groups can be at an increased risk of vitamin D deficiency (defined as a 25-hydroxyvitamin D [25(OH)D] status ≤30 nmol/L). The vitamin D status of ethnic minority groups has been examined both in UK and European populations, but not in the Irish context. The aim of this study is to assess the vitamin D status from a selection of the Dublin population of South East Asian descent. A search was conducted, using the laboratory information system of St James's Hospital, Dublin, for vitamin D requests by General practitioners. From 2013 to 2016, 186 participants were identified and 25(OH)D analysis was quantified using liquid chromatography-tandem mass spectrometry (LC-MS-MS). Overall, the median age was 32 years, 51% were male, and the 25(OH)D concentration ranged from 10 to 154 nmol/L. In total, 66.7% of the total sample were vitamin D deficient and 6.7% had a 25(OH)D status greater than 50 nmol/L (the 25(OH)D concentration defined by the EU as 'sufficient'). Females had a significantly higher 25(OH)D concentration than males (25.0 vs. 18.0 nmol/L; p = 0.001) but both groups had a significant proportion with deficient status (56% and 76.8%, respectively). Seasonal variation of 25(OH)D was not evident while high rates of deficiency were also observed in those aged <18 years and >50 years. Given the importance of vitamin D for health, this sub-population could be at a significantly increased risk of rickets, impaired bone metabolism, and osteoporosis. In addition, vitamin D deficiency has been associated with several non-bone related conditions, including cardiovascular disease and diabetes. Currently, there is no unique vitamin D intake or vitamin D status maintenance guidelines recommended for adults of non-Irish descent; this needs to be considered by the relevant public health bodies in Ireland.

RESUMEN

An increasing ageing population leads to greater demand for care services to help maintain people in their own homes. Physical activity programmes have been shown to improve older adults' functional capacity, enabling the older adult to live independently and maintain functional status. There has been a lack of quality research conducted around physical activity within the landscape of home care services. We describe a feasibility study of implementing the Care to Move (CTM) programme in older adults receiving low-level home care. A Phase 1 mixed-methods feasibility study design will explore the recruitment, attrition, retention, costs to deliver and data loss. It will also explore the acceptability and impact of the CTM programme on older adults and thematic analysis of data collected from older people, home care workers and relevant stakeholders through use of semi-structured interviews and focus groups. We will measure functional status and fall outcomes in older adults receiving low levels of home care, facilitating this population to continue living independently at home and providing data currently not known around this group.

RESUMEN

PURPOSE: Maintaining skeletal muscle function throughout life is a crucial component of successful ageing. Adequate vitamin D status may be important in preserving muscle function. We aimed to determine the association between impaired muscle function and serum vitamin D status in community-dwelling older adults. Falls were explored as a secondary aim. METHODS: Data were analyzed from adults aged ≥60 years, from Wave 6 of the English Longitudinal Study of Aging (ELSA). Handgrip strength (HGS) and the short physical performance battery (SPPB) were employed as measures of muscle strength and physical function, respectively. Serum 25-hydroxyvitamin D [25(OH)D] was assessed with concentration <30 nmol/L classed as vitamin D deficient. RESULTS: The study comprised 4157 community-dwelling adults with a mean age of 69.8 (SD 6.9). Overall, 30.6% had low HGS and 12.7% had low SPPB (≤6). Participants with the lowest serum 25(OH)D (<30 nmol/L) had the highest prevalence of impaired muscle strength and performance (40.4% and 25.2%) compared with participants with levels ≥50 nmol/L (21.6% and 7.9%). Consistent with this, vitamin D deficiency (<30 nmol/L) was a significant determinant of low HGS (OR 1.44 [1.22, 1.71], p<0.001) and poor physical performance (OR 1.65 [1.31, 2.09], p<0.001) in the logistic regression models. Older adults partaking in regular moderate physical activity had significantly lower odds of impaired muscle strength (OR 0.65 [0.58, 0.79]) and physical function (OR 0.30 [0.24, 0.38]), p <0.001, respectively. Single or multiple falls (15.8% and 10.5% in past year) were not associated with vitamin D status. CONCLUSION: Vitamin D deficiency was associated with impaired muscle strength and performance in a large study of community-dwelling older people. It is generally accepted that vitamin D deficiency at the <30 nmol/L cut-off should be reversed to prevent bone disease, a strategy that may also protect skeletal muscle function in ageing.

RESUMEN

Vitamin D deficiency is often associated with adverse health outcomes in older adults. The circulating 25-hydroxyvitamin D (25(OH)D) status predominately relies on UV exposure. However, the extent of which northerly latitude exasperates deficiency is less explored in ageing. We aimed to investigate vitamin D deficiency in community-dwelling, older adults, residing at latitudes 50-55° north. This study was comprised of 6004 adults, aged >50 years from wave 6 (2012-2013) of the English Longitudinal Study of Ageing (ELSA). Deficiency was categorised by two criteria: Institute of Medicine (IOM) (<30 nmol/L) and Endocrine Society (ES) (<50 nmol/L). The overall prevalence of Institute of Medicine (IOM) and Endocrine Society (ES) definitions of deficiency were 26.4% and 58.7%, respectively. Females (odds ratio (OR) 1.23; CI: 1.04-1.44), those aged 80+ (OR: 1.42; CI: 1.01-1.93), smoking (OR: 1.88; CI: 1.51-2.34); of non-white ethnicity (OR: 3.8; CI:2.39-6.05); being obese (OR: 1.32; CI:1.09-1.58), and of poor self-reported health (OR:1.99; CI:1.33, 2.96), were more likely to be vitamin D deficient (by IOM). Residents in the south of England had a reduced risk of deficiency (OR: 0.78; CI:0.64-0.95), even after adjustment for socioeconomic and traditional predictors (obesity, age, lifestyle, etc.) of vitamin D status. Other factors, such as being retired, having a normal BMI, engaging in regular vigorous physical activity, vitamin D supplement use, sun travel, and summer season were also significantly positive correlates of deficiency. Similar results were observed for the ES cut-off definition. Importantly, more than half of adults aged >50 years had 25(OH)D concentrations <50 nmol/L. These findings demonstrate that low vitamin D status is highly prevalent in older English adults and the crucial importance of public health strategies throughout midlife and older age to achieve optimal vitamin D status.

RESUMEN

Sunshine is considered to be the most important source of vitamin D. Due to an increased risk of skin cancer, sun avoidance is advised, but this directly contributes to the high prevalence of vitamin D deficiency. The simple solution is to advise vitamin D supplementation. The aim of this study was to examine the absolute and relative contribution of sunshine and supplementation to vitamin status. This study was a secondary analysis of an RCT of 92 Crohn's disease patients in remission (49% female, median age = 44). Participants were randomized to 2000 IU day-1 of vitamin D3 or placebo for 1 year, with 25-hydroxyvitamin D (25(OH)D) being measured at baseline and every 4 months. Based on participant's place of residence, daily ambient UVB dose at wavelengths that can induce vitamin D synthesis (D-UVB) was obtained. Cumulative and weighted ambient D-UVB (cw-D-UVB) exposure prior to each blood draw was calculated for each participant. Linear regression analysis and multilevel modeling were used to examine the association between UVB exposure, supplementation and 25(OH)D concentration. There was considerable annual variation in D-UVB, cw-D-UVB and 25(OH)D. Both supplementation and cw-D-UVB were found to be strongly associated with 25(OH)D: in multilevel model, an increase of approximately 6 nmol L-1 for every 100 kJ m-2 in cw-D-UVB was found, among those receiving placebo and supplementation (P < 0.0001). Treatment was associated with increase of 23 nmol L-1 (P < 0.0001). Sunshine is an important determinant of 25(OH)D concentration, even in those who are taking high-dose vitamin D supplements and reside at a higher mid-latitude location.
