Key messages

• the review identifies a wide range of community-based interventions across health, social and wellbeing settings
• interventions include peer support, self-help, exercise-based programmes and digital approaches
• many studies report positive effects on mental health and wellbeing outcomes
• some interventions incorporate elements of social integration and social care support
• outcome measures are uneven, with fewer studies examining harder endpoints such as hospitalisation or mortality
• limited attention is given to equity and subgroup analysis.

Policy implications

• community-based interventions may support neighbourhood health and care goals around prevention and wellbeing
• neighbourhood models could benefit from drawing on existing community and voluntary sector provision
• more consistent outcome measurement would support commissioning and scale-up
• equity considerations should be more explicitly built into intervention design and evaluation.

Gaps

• lack of standardised outcome metrics across studies
• limited evidence on long-term or system-level impacts
• fewer studies examine impacts on service use or clinical outcomes
• minimal focus on differential effects across population subgroups.

Commentary
This scoping review highlights the breadth of community-based interventions operating within the UK that contribute to mental health and wellbeing. The diversity of approaches reflects the range of ways communities support health outside formal clinical settings.

From a neighbourhood health and care perspective, these interventions align with preventive and place-based ambitions. Peer support, exercise and self-help initiatives can complement statutory services by addressing wellbeing, connection and resilience within local communities.

However, the review also exposes weaknesses in the evidence base. Outcome measures vary widely, making it difficult to compare interventions or assess their contribution to system-level outcomes such as reduced service use.

The limited focus on equity is particularly notable. Without subgroup analysis, it remains unclear which interventions work best for different communities or whether benefits are distributed evenly.

Overall, the review suggests that community-based interventions have potential value within neighbourhood health and care, but stronger evaluation and clearer attention to equity are needed to inform commissioning and integrated service design.

Key messages

• the review focuses on community-based interventions targeting older adults
• interventions are delivered in community settings and include social, health and preventive approaches
• evidence suggests benefits for physical functioning and wellbeing
• some studies indicate potential reductions in use of acute services
• interventions vary widely in design, intensity and outcomes measured
• social care integration is less frequently examined within the reviewed studies.

Policy implications

• community-based interventions may support neighbourhood health and care aims around prevention and ageing well
• neighbourhood models could integrate community programmes to help maintain function and independence
• stronger links between community interventions and social care services may enhance impact
• commissioners may need clearer evidence on which interventions deliver sustained benefits.

Gaps

• many studies are short term, limiting understanding of longer-term impact
• limited number of high-powered randomised controlled trials
• weaker evidence on effects on service use and system outcomes
• limited focus on how community interventions integrate with social care.

Commentary
This systematic review adds to evidence that community-based interventions can play a role in supporting health and wellbeing among older adults. Improvements in physical function and wellbeing align with neighbourhood health and care ambitions to promote independence and prevent deterioration.

From a neighbourhood perspective, community settings offer accessible and familiar environments that may encourage engagement among older people. Such interventions can complement formal health and social care by addressing needs earlier and closer to home.

However, the review also highlights limitations in the evidence base. Short study durations and a lack of high-powered trials make it difficult to draw firm conclusions about long-term outcomes or effects on acute service use. There is also limited attention to social care integration. Without clearer links to care pathways and support systems, community interventions risk operating in parallel rather than as part of coordinated neighbourhood health and care.

Overall, the review suggests that community-based interventions have potential value for older populations within neighbourhood health and care, but stronger, longer-term and more integrated evaluation is needed to inform policy and practice.
