Background Cocooning or shielding, i.e. staying at home and reducing face-to-face interaction with other people, was an important part of the response to the COVID-19 pandemic for older people. However, concerns exist regarding the long-term adverse effects cocooning may have on their physical and mental health. Aim To examine health trajectories and healthcare utilization while cocooning in a cohort of community-dwelling people aged ≥70 years. Design Survey of 150 patients (55% female, mean age 80 years, mean Clinical Frailty Scale Score 4.8) attending ambulatory medical services in a large urban university hospital. Methods The survey covered four broad themes: access to healthcare services, mental health, physical health and attitudes to COVID-19 restrictions. Survey data was presented descriptively. Results Almost 40% (59/150) reported that their mental health was ‘worse’ or ‘much worse’ while cocooning, while over 40% (63/150) reported a decline in their physical health. Almost 70% (104/150) reported exercising less frequently or not exercising at all. Over 57% (86/150) of participants reported loneliness with 1 in 8 (19/150) reporting that they were lonely ‘very often’. Half of participants (75/150) reported a decline in their quality of life (QOL). Over 60% (91/150) agreed with government advice for those ≥70 years but over 40% (61/150) reported that they disliked the term ‘cocooning’. Conclusions Given the likelihood of further restrictions in coming months, clear policies and advice for older people around strategies to maintain social engagement, manage loneliness, continue physical activity and access timely medical care and rehabilitation services should be a priority.

UVB-induced skin synthesis is considered the key source of vitamin D, yet exposure to UVB is poorly accounted for in epidemiological studies. The aim of this study was to examine the association of serum 25-hydroxyvitamin D [25(OH)D] concentration with accurately measured ambient UVB dose, sun enjoyment, supplements, and other factors. An all-Irish cohort of community-dwelling participants aged >60 y [median age: 73; 67% female; median 25(OH)D: 54.5 nmol/L] was used. Participants from this large, cross-sectional study completed a questionnaire to provide information on demographic factors and lifestyle (including supplement use and sun enjoyment). The Tropospheric Emission Monitoring Internet Service database was used to extract the daily ambient UVB dose at wavelengths that could induce vitamin D synthesis (D-UVB) over Ireland (latitude: 51°N-55°N). Blood sampling occurred throughout the year. Ambient exposure at the place of residence was calculated for each participant individually. Associations between determinants and serum 25(OH)D concentration were examined in a multivariate model. Random forest analysis was used to establish prediction models of vitamin D deficiency, and area under the curve (AUC) is shown. In total, 5138 individuals were included. Median D-UVB was 63 mJ/cm, which varied between seasons and latitudes, despite the small latitude differential. Vitamin D supplementation (β = 27.7; < 10 × 10), D-UVB (β = 1.58 per 1000 mJ/cm; < 10 × 10), and sun enjoyment (β = 6.6; < 0.001) were strongly positively associated with serum 25(OH)D. Those who avoided sunshine were largely at risk of deficiency (<40 nmol/L), whereas those who enjoyed sunshine tended to be vitamin D sufficient (≥50 nmol/L). D-UVB and sun enjoyment improved prediction of deficiency in non-supplement-taking individuals; the overall AUC improved by 3.5%. D-UVB and sun enjoyment are important predictors of vitamin D status, even in this elderly population at northern latitudes. Accurate estimation of ambient UVB can help to further clarify the role of other determinants of vitamin D status and inform sunshine recommendation guidelines.

supplement use was the most important determinant of vitamin D status. Vitamin D fortified milk and spending time in the sun, even in the oldest old may also be useful strategies to improve 25(OH)D.

This study draws on data from over 5000 European adults of 60+ years and shows that better folate and related B-vitamin status may have a positive impact on mental health in older adults.

This analysis combining data from two health systems shows that area deprivation is an independent risk factor for cognitive dysfunction in older adults. Adults living in areas of greatest socioeconomic deprivation may benefit from targeted strategies aimed at improving modifiable risk factors for dementia. Further cross-national analysis investigating the impact of area- level deprivation is needed to address socioeconomic disparities and shape future policy to improve health outcomes in older adults.© 2018 American Geriatrics Society and Wiley Periodicals, Inc.
