Background The 2022 World Falls Guidelines recommend assessing concerns (or ‘fears’) about falling in multifactorial fall risk assessments. However, the evidence base for this recommendation is limited. This review evaluated the evidence for concerns about falling as an independent predictor of future falls, applying the Bradford Hill criteria for...

Background The occurrence of falls in adults 65+ years remains a common and costly issue worldwide. There is current evidence to suggest that falls can be prevented using evidence-based strength and balance interventions, such as the six-month Falls Management Exercise (FaME) programme. Perspectives of multiple key partners and providers of the FaM...

Introduction A national research priority for people living with bile acid diarrhoea (BAD) is effective treatment options to improve their quality of life. This study aims to evaluate the feasibility of conducting a randomised controlled trial (RCT) of a novel healthy dietary pattern (The 8×5 Diet) to inform a future, larger trial. Methods and ana...

Background A large proportion of older adults are pre-frail. Interventions aimed at this group provide opportunity to reduce progression of physical frailty. The aim of this overview of reviews is to evaluate evidence for non-pharmacological interventions for the prevention/reversal of physical frailty in community-dwelling adults aged ≥ 50 years....

Background The older population is increasingly reliant on social care, especially those who are frail. However, an estimated 1.5 million people over 65 in England have unmet care needs. The relationship between receiving care, or receiving insufficient care, and changes in frailty status remains unclear. Objectives To investigate the associations...

Background Despite the comparatively high prevalence of possible sarcopenia among young-old adults in the community, there is currently no available and effective social media-based intervention to increase the awareness and change the behavior of the target population to prevent sarcopenia. Using co-design methodology, we developed a multicomponen...

Purpose Physical frailty is prevalent in lung transplant (LTx) candidates and is linked to adverse outcomes preoperatively and postoperatively.

Background Despite the comparatively high prevalence of possible sarcopenia among young-old adults in the community, there is currently no available and effective social media-based intervention to increase the awareness and behaviour of the target population in order to prevent sarcopenia. Using co-design methodology, we developed a multicomponent...

Increasing physical activity (PA) and/or decreasing sedentary behaviors is important in the delay and prevention of long-term conditions. PA can help maintain function and independence and decrease the need for hospitalization/institutionalization. Activity rates often decline in later life resulting in a need for interventions that encourage uptak...

Possible sarcopenia refers to low muscle strength. Prevalence of possible sarcopenia is estimated to be significantly higher in community-dwelling older adults than that of confirmed or severe sarcopenia. However, there are currently far fewer non-pharmacological intervention strategies for possible sarcopenia than for sarcopenia in the community....

For older people, physical inactivity increases fall risk as well as other preventable health conditions. Despite the well-documented benefits of physical activity, uptake and adherence continue to challenge efforts aimed at increasing physical activity and reducing falls. Nested within a randomized controlled trial, this study reports on the facto...
