Within the fitness, health and wellness sectors, discussion often focuses on longevity, performance optimisation and disease prevention later in life. However, recent population data presents a more concerning reality: for many people across England and Wales, poor health is beginning far earlier than expected.
New figures from the Office for National Statistics (ONS) show that where a person lives is a strong predictor of how long they can expect to live in good health. For health and fitness professionals, this challenges assumptions about personal choice, motivation and access, and highlights the significant influence of environmental and socioeconomic factors on health outcomes.
Postcodes as predictors of healthy life expectancy
Healthy life expectancy refers to the number of years an individual is expected to live in good or very good health. According to the ONS, the gap in healthy life expectancy between the most and least deprived areas now stands at around 20 years.
In England, the difference is 19.3 years for males and 20.1 years for females. In Wales, inequalities are even greater, at 20.6 years for males and 23.1 years for females.
In practical terms, people living in the most deprived areas can expect to spend less than 50 years in good health, while those in the least deprived areas often remain healthy into their late 60s or early 70s. These disparities cannot be explained by genetics alone and reflect longstanding inequalities relating to housing, education, employment, income and access to health-promoting resources.
ONS data also indicates that healthy life expectancy has declined across all levels of deprivation in recent years. While this decline affects the whole population, the gap between affluent and deprived areas remains wide.
Health decline before 50: A loss of opportunity
One of the most concerning findings is that healthy life expectancy in deprived areas now frequently falls below 50 years. For individuals born between 2022 and 2024, projections suggest that the onset of poor health will occur much earlier for those living in less advantaged communities.
England
- Boys born in the least deprived areas can expect around 69.2 years in good health, representing approximately 83% of their total life expectancy. In the most deprived areas, this falls to 49.8 years, around 68% of a shorter lifespan.
- Girls in the least deprived areas can expect roughly 68.5 healthy years. In contrast, girls born in the most deprived areas are projected to spend only 48.2 years in good health, equating to about 62% of their total life expectancy.
Wales
- Boys in the most deprived areas have a healthy life expectancy of approximately 49.7 years, compared with 67.8 years in the least deprived areas.
- Girls experience the greatest disparity, with healthy life expectancy falling to 47.3 years in deprived areas, compared with 66.3 years in more affluent regions.
These figures suggest that in some communities, the window for long-term prevention, rehabilitation and performance-focused interventions is significantly reduced due to the early onset of chronic illness and multi-morbidity.
Understanding the structural causes of inequality
Health outcomes are shaped by far more than individual behaviour. Wider social and environmental factors such as housing quality, employment conditions, access to green space, food security and community infrastructure play a substantial role.
Evidence suggests that improvements in life expectancy achieved prior to the COVID pandemic have stalled or reversed in the most deprived areas. This regression reflects cumulative pressures including financial insecurity, poor living environments and limited access to supportive services. These factors can undermine physical and mental health long before individuals come into contact with clinical care.
In this context, improving health outcomes requires more than promoting exercise participation or improving health literacy alone. Without addressing the environments in which people live and work, individual-level interventions are likely to have limited impact.
Policy response and system capacity
In response to these inequalities, the Government has committed to raising healthy life expectancy in the most deprived areas as part of the Women’s Health Strategy, with a target increase from around 50 to at least 61 years. This represents a significant challenge.
Achieving this improvement will require coordinated action across healthcare, public health, local authorities and the fitness and physical activity sectors. Clinical services alone are unlikely to be sufficient. Community-based provision, social prescribing, preventive services and closer integration between health and fitness professionals will be essential.
This approach also raises practical questions around workforce capacity, funding and accessibility. Services must be delivered where need is greatest, rather than remaining concentrated in already healthy populations.
Implications for health and fitness professionals
The ONS data makes clear that health inequalities are not narrowing and, in some areas, are widening. For professionals working in exercise, rehabilitation or public health, this necessitates a broader perspective beyond individual programmes and outcomes.
This includes engagement with community health initiatives, support for social prescribing pathways, and advocacy for environments that enable healthy behaviours. It may also require adapting services to reach people earlier in life, with a focus on functional capacity, disease prevention and maintaining independence, rather than long-term optimisation alone.
Bridging a 20-year gap in healthy life expectancy is not solely a policy ambition. It represents a shared responsibility across all sectors involved in health promotion.
