BackgroundCompelling evidence highlights a relationship between greenspace access and mental and physical health. Deprived areas often have limited greenspace, reducing opportunities for communities to benefit. This study systematically reviews evidence on access to greenspace and health inequalities in England, and analyses local authority greenspace strategies to assess how they address local health needs. MethodsA systematic literature review of 47 studies examined the relationship between access (presence, proximity) to greenspace and health inequalities in England. We searched four databases (MEDLINE, Embase, Web of Science, PyschINFO) for observational articles published between 1992–2021. Included studies were from England, reporting access measures, physical or mental health outcomes, and inequality dimensions such as age and deprivation. Due to methodological differences, we conducted a narrative synthesis and assessed article quality. Additionally, we analysed publicly available local authority greenspace strategies in England published between 2012–2024, sourced from OHID regional teams. A content analysis was performed extracting data on health policy and outcomes, demographics, inequalities, environmental change, monitoring and evaluation. FindingsThe systematic review found mixed evidence on the relationship between greenspace access and health inequalities. Higher greenspace coverage in deprived areas was linked to reduced mortality risk, while improved mental health was associated with increased access among men and those with lower education. Despite proximity to parks, residents in deprived areas reported poor greenspace access. The policy analysis revealed half of local authorities lack a greenspace strategy. Most recognise greenspace as important for physical health, and increasingly reference mental health, though few consider how green infrastructure improvements could address local inequalities. InterpretationThis study highlights the benefits of improved access to green space for physical and mental health, particularly for deprived populations. Local authorities can utilise green space strategies to address local health needs and national government should strategically incorporate greenspace access in planning policy to tackle health inequalities. FundingThis study was funded by the following NIHR Health Protection Research Units (HPRU) in partnership with UK Health Security Agency (UKHSA): the Environmental Change and Health HPRU at London School of Health and Tropical Medicine and University College London (HPRU ECH), (Grant number: NIHR200909). The funding source had no role in review design, the collection, analysis and interpretation of data, the writing of the article or the decision to submit it for publication.
