RESUMO
Physical activity (PA) is a known approach for managing anxiety symptoms in older adults. This systematic review and meta-analysis address the benefits of PA and its dimensions (frequency, session time, type, and intervention period) on anxiety symptoms in older adults aged 65 years and above. Searches covered eight databases reporting eight randomized controlled trials (RCTs) and five non-RCTs. Meta-analysis of RCTs (standardized mean difference = -0.41; 95% confidence interval [-0.58, -0.24]; p < .00001) and Fisher's method of combining p values for non-RCTs supported the effectiveness of PA for managing anxiety symptoms in older adults. Subgroup analysis revealed significant effects for all PA types, session times, frequency, and intervention periods compared with control groups, albeit with different magnitudes of effect. In conclusion, although some dimensions of PA contribute to its effectiveness for anxiety, PA intensity and mode required to maximize PA effects remain unclear.

Age-related changes affect the ratio between two steroid hormones of the hypothalamic-pituitary-adrenal axis, cortisol and dehydroepiandrosterone (sulfate) (DHEA[S]). Physical activity (PA) may buffer the effects of chronic stress and counteract the aging decline of DHEA(S). Therefore, a systematic review was conducted to understand how PA influences physiological markers of cortisol and/or DHEA(S) and whether there is a difference in observational associations or experimental effects in older adults aged 65 years and older. A narrative synthesis was performed on nine observational studies, and meta-analyses were performed on 22 randomized controlled trials. There was low- to moderate-quality evidence that regular PA beneficially reduces cortisol and increases DHEA(S) levels. Subgroup analyses showed no clinically important differences between men and women, different exercise modalities, or health states. The findings cautiously suggest that regular PA of older adults' own choice that they find enjoyable could be recommended to improve cortisol and/or DHEA(S) levels.

BACKGROUND: Managing stress and having good quality sleep are inter-related factors that are essential for health, and both factors seem to be affected by physical activity. Although there is an established bidirectional relationship between stress and sleep, remarkably few studies have been designed to examine the effects of physical activity on cortisol, a key biomarker for stress, and sleep. Research is particularly scarce in older people despite both sleep and cortisol changing with age. This systematic literature review addresses this gap. METHODS: A systematic review was conducted following the PRISMA guidelines. Original, peer-reviewed records of intervention studies such as randomized controlled trials (RCTs) and non-RCTs with relevant control groups were eligible for inclusion. The Participant, Intervention, Comparison, Outcome (PICO) characteristics were (1) adults or older adults (2) physical activity programmes of any duration, (3) controls receiving no intervention or controls included in a different programme, (4) cortisol measurement, and subjective or objective measures of sleep. RESULTS: Ten original studies with low-to-moderate risk of bias were included. Findings from this review indicated with moderate- and low-certainty evidence, respectively, that physical activity was an effective strategy for lowering cortisol levels (SMD [95% CI] = -0.37 [-0.52, -0.21] p < .001) and improving sleep quality (SMD [95% CI] = -0.30 [-0.56, -0.04], p = .02). Caution is needed to generalize these findings to the general population, as included trials were predominantly participants with breast cancer, included few males and no older adults. CONCLUSION: Cortisol regulation and sleep quality are intertwined, and physical activity programmes could improve both in several ways. Further, physical activity may benefit adults with long term conditions or current poor (mental) health states the most, although more research is needed to support this claim fully. Few intervention studies have examined the inter-relationship between cortisol and sleep outcomes in males or older adults, indicating fruitful enquiry for future research.

BACKGROUND: The purpose of this study was to explore perceived changes in physical activity (PA) due to Covid19 stay-at-home and social distancing guidance among older adults. METHODS: Participants (n = 1429, 77% female, 84% ≥60 years) living in Scotland completed an online survey in Summer 2020 measuring PA and wellbeing (indexed through loneliness, and health-related quality of life). The survey included open- and closed-ended questions about how these variables changed in response to Covid19 social distancing and 'shielding' guidelines. RESULTS: From the International Physical Activity Questionnaire (IPAQ), the majority reported high volumes of PA, indicative of being 'moderately' or 'highly' active. When asked specifically about strength training, 12% reported engagement on ≥2d/wk. Most participants reported that PA had changed during this time, citing reduced use of exercise facilities, increased active travel, and online PA classes; although only 16% reported engaging in PA online. CONCLUSIONS: Higher levels of PA were found to be associated with better health-related quality of life. Additional efforts should be made to support PA engagement in older adults, including strength training and other tailored approaches to support individual needs.
RESUMO
This study examined the impact of social distancing during the COVID-19 pandemic on loneliness, wellbeing, and social activity, including social support, in Scottish older adults. A mixed methods online survey was used to examine these factors during social distancing mid-lockdown, July 2020. Participants were asked to state whether loneliness, wellbeing, social activity, and social support had changed since pre-social distancing, and to provide details of strategies used to keep socially active. A total of 1429 adults (84% aged 60+ years) living in Scotland took part. The majority reported that social distancing regulations made them experience more loneliness and less social contact and support. Loneliness during lockdown was higher than reported norms for this age group before the pandemic. A larger social network, more social contact, and better perceived social support seemed to be protective against loneliness and poor wellbeing. Positive coping strategies reported included increasing online social contact with both existing social networks and reconnecting with previous networks, as well as increasing contact with neighbours and people in the community. This underlines the importance of addressing loneliness and social support in older adults but particularly during situations where risk of isolation is high.

BACKGROUND: As part of the design process of a low-cost minimal-contact diabetes prevention intervention, we issued a blood glucose meter to people with impaired glucose regulation (who are at high risk of type 2 diabetes). We conducted a feasibility study to assess the acceptability of this intervention component and whether and how recipients engaged with it. METHODS: A blood glucose meter was given to 19 people identified through primary care, who were asked to use the meter in an exploratory way during a 4-week trial period, to try to understand the effect of different foods on the body. They were advised that they could test as often or as little as they liked and were also asked to keep a food/exercise diary for at least 1 week. They were interviewed about their experiences afterwards. RESULTS: There was a high level of engagement with testing, with the total number of tests recorded ranging from 11 to 114 (median 74) among 18 participants. Fifteen participants tested almost every day during the 4-week period. The cognitive engagement was more limited. All participants commented on their own results, and most were able to relate high or low results to foods eaten and exercise taken, usually in response to prompting. However, there was limited thought or understanding beyond this in terms of longer-term patterns of diet and exercise, and testing was routine rather than experimental. Some participants were confused by conflicting or unexpected results. A few minor problems were reported by participants, such as soreness, inconvenience, and difficulty in getting blood, but never enough to discontinue testing. Several participants stated that the meter was a useful aid as a reminder that they were at high risk of diabetes and served as a prompt that needed to make and/or maintain behaviour changes. CONCLUSIONS: The study suggests that blood glucose monitoring is acceptable to people with impaired glucose regulation and that they would engage with it as part of an intervention to improve their diet. The study has also uncovered potential mechanisms of action for behaviour change.
RESUMO
BACKGROUND: Research supports the use of Web-based interventions to promote physical activity in diabetes management. However, previous interventions have found poor levels of engagement or have not included health professionals and people with diabetes in the design of the tool. OBJECTIVE: To develop and explore the feasibility and indicative effect of a Web-based physical activity promotion intervention in people diagnosed with type 2 diabetes living in remote or rural locations. METHODS: A qualitative approach using focus groups that included patients with diabetes and health professionals were run to identify key concepts, ideas, and features, which resulted in the design of a physical activity website. This site was tested using a quantitative approach with a qualitative 6-month pilot study that adopted a three-armed approach. Participants were randomized into three groups: a control group who received written diabetes-specific physical activity advice; an information Web group, a Web-based group who received the information online; and an intervention Web group, an interactive Web-based group who received online information plus interactive features, such as an activity log, personalized advice, and goal setting. RESULTS: A website was designed based on patient and health professional ideas for effective physical activity promotion. This website was tested with 31 participants, 61% (19/31) male, who were randomized into the groups. Website log-ins decreased over time: 4.5 times in month 1, falling to 3 times in month 6. Both the information Web group-mean 134.6 (SD 123.9) to mean 154.9 (SD 144.2) min-and the control group-mean 118.9 (SD 103.8) to mean 126.1 (SD 93.4) min, d=0.07-increased time spent in moderate-to-vigorous physical activity, but this decreased in the intervention Web group-mean 131.9 (SD 126.2) to mean 116.8 (SD 107.4) min. CONCLUSIONS: Access to online diabetes-specific physical information was effective in promoting physical activity in people with type 2 diabetes; access to interactive features was not associated with increases in activity.
