Preventive interventions for the second half of life: a systematic review

HAJAT Cother, et al

Objective: Recent improvements in life expectancy globally require intensified focus on noncommunicable diseases and age-related conditions. The purpose of this article is to inform the development of age-specific prevention guidelines for adults aged 50 and above, which are currently lacking. Data Source: PubMed, Cochrane database, and Google Scholar and explicit outreach to experts in the field. Study Inclusion and Exclusion Criteria: Meta-analyses, intervention-based, and prospective cohort studies that reported all-cause mortality, disease-specific mortality, or morbidity in adults were included. Data Extraction: A systematic review was undertaken in 2015 using search terms of a combination of and “intervention,” “mortality,” “reduction,” “improvement,” “death,” and “morbidity.” Data Synthesis: Interventions were categorized according to the Center for Evidence-Based Medicine Level of Evidence framework. Results: A summary table reports for each intervention the impact, strength of evidence, initiation, duration, and details of the intervention. Age-decade-specific preventive recommendations have been proposed relating to physical activity, diet, tobacco and alcohol use, medication adherence, screening and vaccination, and mental and cognitive health. Conclusion: Clear recommendations have been made according to the existing evidence base, but further research investment is needed to fill the many gaps. Further, personalized approaches to healthy aging complemented by population-wide approaches and broader cross-sector partnerships will help to ensure greater longevity is an opportunity, rather than a burden, for society.

Effects of forest therapy on depressive symptoms among adults: a systematic review

LEE Insook, et al

This study systematically reviewed forest therapy programs designed to decrease the level of depression among adults and assessed the methodological rigor and scientific evidence quality of existing research studies to guide future studies. This systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The authors independently screened full-text articles from various databases using the following criteria: (1) intervention studies assessing the effects of forest therapy on depressive symptoms in adults aged 18 years and older; (2) studies including at least one control group or condition; (3) peer-reviewed studies; and (4) been published either in English or Korean before July 2016. The Scottish Intercollegiate Guideline Network measurement tool was used to assess the risk of bias in each trial. In the final sample, 28 articles (English: 13, Korean: 15) were included in the systematic review. We concluded that forest therapy is an emerging and effective intervention for decreasing adults' depression levels. However, the included studies lacked methodological rigor. Future studies assessing the long-term effect of forest therapy on depression using rigorous study designs are needed.

Health and well-being benefits of spending time in forests: systematic review

OH Byeongsang, et al

Background: Numerous studies have reported that spending time in nature is associated with the improvement of various health outcomes and well-being. This review evaluated the physical and psychological benefits of a specific type of exposure to nature, forest therapy. Method: A literature search was carried out using MEDLINE, PubMed, ScienceDirect, EMBASE, and ProQuest databases and manual searches from inception up to December 2016. Key words: “Forest” or “Shinrin -Yoku” or “Forest bath” AND “Health” or “Wellbeing”. The methodological quality of each randomized controlled trials (RCTs) was assessed according to the Cochrane risk of bias (ROB) tool. Results: Six RCTs met the inclusion criteria. Participants’ ages ranged from 20 to 79 years. Sample size ranged from 18 to 99. Populations studied varied from young healthy university students to elderly people with chronic disease. Studies reported the positive impact of forest therapy on hypertension (n = 2), cardiac and pulmonary function (n = 1), immune function (n = 2), inflammation (n = 3), oxidative stress (n = 1), stress (n = 1), stress hormone (n = 1), anxiety (n = 1), depression (n = 2), and emotional response (n = 3). The quality of all studies included in this review had a high ROB. Conclusion: Forest therapy may play an important role in health promotion and disease prevention. However, the lack of high-quality studies limits the strength of results, rendering the evidence insufficient to establish clinical practice guidelines for its use. More robust RCTs are warranted.

Quantifying the benefits of peer support for people with dementia: a social return on investment (SROI) study

WILLIS Elizabeth, SEMPLE Amy C., de WAAL Hugo

Objective: Peer support for people with dementia and carers is routinely advocated in national strategies and policy as a post-diagnostic intervention. However there is limited evidence to demonstrate the value these groups offer. This study looked at three dementia peer support groups in South London to evaluate what outcomes they produce and how much social value they create in relation to the cost of investment. Methods: A Social Return on Investment (SROI) analysis was undertaken, which involves collecting data on the inputs, outputs and outcomes of an intervention, which are put into a formula, the end result being a SROI ratio showing how much social value is created per £1 of investment. Results: Findings showed the three groups created social value ranging from £1.17 to £5.18 for every pound (£) of investment, dependent on the design and structure of the group. Key outcomes for people with dementia were mental stimulation and a reduction in loneliness and isolation. Carers reported a reduction in stress and burden of care. Volunteers cited an increased knowledge of dementia. Conclusions: This study has shown that peer groups for people with dementia produce a social value greater than the cost of investment which provides encouraging evidence for those looking to commission, invest, set up or evaluate peer support groups for people with dementia and carers. Beyond the SROI ratio, this study has shown these groups create beneficial outcomes not only for the group members but also more widely for their carers and the group volunteers.

What works for wellbeing? A systematic review of wellbeing outcomes for music and singing in adults

DAYKIN Norma, et al

Aims: The role of arts and music in supporting subjective wellbeing (SWB) is increasingly recognised. Robust evidence is needed to support policy and practice. This article reports on the first of four reviews of Culture, Sport and Wellbeing (CSW) commissioned by the Economic and Social Research Council (ESRC)-funded What Works Centre for Wellbeing (https://whatworkswellbeing.org/). Objective: To identify SWB outcomes for music and singing in adults. Methods: Comprehensive literature searches were conducted in PsychInfo, Medline, ERIC, Arts and Humanities, Social Science and Science Citation Indexes, Scopus, PILOTS and CINAHL databases. From 5,397 records identified, 61 relevant records were assessed using GRADE and CERQual schema. Results: A wide range of wellbeing measures was used, with no consistency in how SWB was measured across the studies. A wide range of activities was reported, most commonly music listening and regular group singing. Music has been associated with reduced anxiety in young adults, enhanced mood and purpose in adults and mental wellbeing, quality of life, self-awareness and coping in people with diagnosed health conditions. Music and singing have been shown to be effective in enhancing morale and reducing risk of depression in older people. Few studies address SWB in people with dementia. While there are a few studies of music with marginalised communities, participants in community choirs tend to be female, white and relatively well educated. Research challenges include recruiting participants with baseline wellbeing scores that are low enough to record any significant or noteworthy change following a music or singing intervention. Conclusions: There is reliable evidence for positive effects of music and singing on wellbeing in adults. There remains a need for research with sub-groups who are at greater risk of lower levels of wellbeing, and on the processes by which wellbeing outcomes are, or are not, achieved.

Interventions to reduce social isolation and loneliness among older people: an integrative review


Loneliness and social isolation are major problems for older adults. Interventions and activities aimed at reducing social isolation and loneliness are widely advocated as a solution to this growing problem. The aim of this study was to conduct an integrative review to identify the range and scope of interventions that target social isolation and loneliness among older people, to gain insight into why interventions are successful and to determine the effectiveness of those interventions. Six electronic databases were searched from 2003 until January 2016 for literature relating to interventions with a primary or secondary outcome of reducing or preventing social isolation and/or loneliness among older people. Data evaluation followed Evidence for Policy and Practice Information and Co‐ordinating Centre guidelines and data analysis was conducted using a descriptive thematic method for synthesising data. The review identified 38 studies. A range of interventions were described which relied on differing mechanisms for reducing social isolation and loneliness. The majority of interventions reported some success in reducing social isolation and loneliness, but the quality of evidence was generally weak. Factors which were associated with the most effective interventions included adaptability, a community development approach, and productive engagement. A wide range of interventions have been developed to tackle social isolation and loneliness among older people. However, the quality of the evidence base is weak and further research is required to provide more robust data on the effectiveness of interventions. Furthermore, there is an urgent need to further develop theoretical understandings of how successful interventions mediate social isolation and loneliness.

Effectiveness and cost-effectiveness of community singing on mental health-related quality of life of older people: randomised controlled trial

COULTON Simon, et al

Aims: This study aimed to evaluate the effectiveness and cost-effectiveness of community group singing for a population of older people in England. Method: A pilot pragmatic individual randomised controlled trial comparing group singing with usual activities in those aged 60 years or more. Results: A total of 258 participants were recruited across five centres in East Kent. At 6 months post-randomisation, significant differences were observed in terms of mental health-related quality of life measured using the SF12 in favour of group singing. In addition, the intervention was found to be marginally more cost-effective than usual activities. At 3 months, significant differences were observed for the mental health components of quality of life, anxiety and depression. Conclusions: Community group singing appears to have a significant effect on mental health-related quality of life, anxiety and depression, and it may be a useful intervention to maintain and enhance the mental health of older people.

A review of the basic principles of sustainable community-based volunteering approaches to tackling loneliness and social isolation among older people


This study examines the social, economic and environmental conditions that enable community-based volunteering projects to reduce loneliness and isolation in older people to become successful. It also identifies barriers to volunteering approaches, and how they can be tackled. The study involved a literature review, consultation with stakeholders, and an analysis of eight case studies in Wales. Drawing on the findings, it also sets out a Theory of Change to show how programmes have the potential to reduce loneliness and social isolation and provides a framework for the future self-evaluation of programmes. The study found that schemes employ a range of approaches in order to engage and support their clients, including in-home visits, telephone befriending, and group activities. This can be influenced by funding or its ability to support the project’s aims and outcomes. Other key findings highlight the need for schemes to be able to accurately assess the social and emotional status of older people so as to deliver appropriate interventions; for schemes to target effectively to reach those most at risk. It also found that schemes adopting a participatory approach which places local people at the heart and schemes which focused on smaller geographical areas tended to be more effective. The report makes eight recommendations, which include the development of a standard method or tools for monitoring and evaluating volunteer-led schemes.

Effectiveness of complex falls prevention interventions in residential aged care settings: a systematic review

FRANCIS-COAD Jacqueline, et al

Objective: The objective of this review was to synthesize the best available evidence for the effectiveness of complex falls prevention interventions delivered at two or more of the following levels: resident, facility or organization, on fall rates in the residential aged care (RAC) population. Introduction: Preventing falls in the high risk RAC population is a common global goal with acknowledged complexity. Previous meta-analyses have not specifically addressed complexity, described as falls prevention intervention delivery at multiple levels of a RAC organization, to determine its effect on fall outcomes. Inclusion criteria: The current review considered studies that included participants who were aged 65 years and over residing in long-term care settings providing 24-hour supervision and/or care assistance. Studies that evaluated complex falls prevention interventions delivered by single discipline or multidisciplinary teams across at least two or all of the following levels: residents, RAC facility and RAC organization were eligible. Experimental study designs including randomized controlled trials, controlled clinical trials and quasi-experimental trials that reported on measures related to fall incidence were considered, namely, rate of falls (expressed as the number of falls per 1000 occupied bed days), the number of participants who became fallers (expressed as the number of participants who fell once or more) and the rate of injurious falls (expressed as the number of falls with injury per 1000 occupied bed days). Methods: A three-step search strategy was undertaken, commencing with an initial scoping search of MEDLINE and CINAHL databases prior to an extensive search of all relevant published literature, clinical trial registries and gray literature. Two independent reviewers assessed selected studies for methodological validity using the standardized critical appraisal instrument from the Joanna Briggs Institute System for the Unified Management, Assessment and Review of Information (JBI SUMARI). Data were extracted from the selected studies using the standardized data extraction tool from JBI SUMARI. Quantitative data were pooled in statistical meta-analysis for rate of falls, the number of participants who became fallers and the rate of injurious falls. Meta-analysis was conducted using a random-effect model with heterogeneity assessed using the standard Chi-squared and I2 index. Where statistical pooling was not possible, study findings were presented in narrative form. Results: Twelve studies were included in this review with seven being eligible for meta-analysis. Complex falls prevention interventions delivered at multiple levels in RAC populations did not show a significant effect in reducing fall rates (MD = −1.29; 95% CI [−3.01, 0.43]), or the proportion of residents who fell (OR = 0.76; 95% CI [0.42, 1.38]). However, a sensitivity analysis suggested complex falls prevention interventions delivered with additional resources at multiple levels had a significant positive effect in reducing fall rates (MD = −2.26; 95% CI [−3.72, −0.80]). Conclusions: Complex falls prevention interventions delivered at multiple levels in the RAC population may reduce fall rates when additional staffing, expertise or resources are provided. Organizations may need to determine how resources can be allocated to best address falls prevention management. Future research should continue to investigate which combinations of multifactorial interventions are effective.

Interventions to prevent and reduce excessive alcohol consumption in older people: a systematic review and meta-analysis

KELLY Sarah, et al

Background: harmful alcohol consumption is reported to be increasing in older people. To intervene and reduce associated risks, evidence currently available needs to be identified. Methods: two systematic reviews in older populations (55+ years): (1) Interventions to prevent or reduce excessive alcohol consumption; (2) Interventions as (1) also reporting cognitive and dementia outcomes. Comprehensive database searches from 2000 to November 2016 for studies in English, from OECD countries. Alcohol dependence treatment excluded. Data were synthesised narratively and using meta-analysis. Risk of bias was assessed using NICE methodology. Reviews are reported according to PRISMA. Results: thirteen studies were identified, but none with cognition or dementia outcomes. Three related to primary prevention; 10 targeted harmful or hazardous older drinkers. A complex range of interventions, intensity and delivery was found. There was an overall intervention effect for 3- and 6-month outcomes combined (8 studies; 3,591 participants; pooled standard mean difference (SMD) −0.18 (95% CI −0.28, −0.07) and 12 months (6 studies; 2,788 participants SMD −0.16 (95% CI −0.32, −0.01) but risk of bias for most studies was unclear with significant heterogeneity. Limited evidence (three studies) suggested more intensive interventions with personalised feedback, physician advice, educational materials, follow-up could be most effective. However, simple interventions including brief interventions, leaflets, alcohol assessments with advice to reduce drinking could also have a positive effect. Conclusions: alcohol interventions in older people may be effective but studies were at unclear or high risk of bias. Evidence gaps include primary prevention, cost-effectiveness, impact on cognitive and dementia outcomes.
