A Health MOT Is Just the Beginning of Real Prevention

False Starts in Public Health

When Devi Sridhar celebrates the introduction of free cholesterol testing on the NHS and blood pressure checks in pharmacies, I applaud her enthusiasm for early detection. But as a lecturer in social policy at the University of Glasgow, I want to challenge the notion that such initiatives are sufficient to tackle the nation's health challenges.

We must distinguish between identifying risk factors and implementing meaningful prevention strategies. Screening is merely the first phase of any public health programme — it identifies those who may be at risk but offers no solutions to the underlying conditions that create those risks in the first place.

"Sridhar's proposed five-point health MOT is undoubtedly valuable, but it is better understood as identifying risk rather than preventing disease. Prevention is what comes next: enabling people to make changes that improve health and reduce that risk."

The Downstream Fallacy

Public health experts have long drawn a distinction between upstream and downstream interventions. Upstream approaches target the social determinants of health — poverty, housing, employment, food security, and access to green spaces. Downstream interventions, like screening programmes, focus on individual-level responses.

Yet our current system often treats these two categories as if they were equivalent. A health MOT might flag that someone has borderline hypertension or elevated cholesterol, but it fails to address why those conditions exist in the first place. It's like detecting a leak in a dam without fixing the underlying water pressure.

This is where many screening initiatives fall short — they create false expectations of action, while offering no real pathway forward for individuals who find themselves flagged as 'at risk'. The burden of change becomes personal, even when structural issues are at play.

Individual Responsibility vs. Structural Reality

The assumption behind many health interventions is that people will respond rationally to health advice and make better choices if they're simply given the information. But this view ignores the lived realities of those most affected by poor health outcomes — particularly those in low-income communities, those with insecure employment, or individuals facing linguistic or cultural barriers.

These groups often have less access to nutritious food, safe spaces for exercise, and reliable transportation to medical appointments. They are also more likely to be stigmatized for their health status, which can lead to further isolation and disengagement from the healthcare system.

When we tell people that they're at risk simply because they've had a blood pressure check, without providing the resources needed to manage that risk, we're perpetuating a cycle of blame rather than building support. The problem isn't necessarily what someone eats or how much they exercise — it's the environment in which those choices are made.

The Limits of Screening

Dr James Hibberd, a GP in London, makes an important point: screening alone is not enough. He warns that pushing for annual 'health MOTs' without corresponding investment in community services could overload already strained general practices and create unrealistic expectations about what the NHS can deliver.

He's right to be concerned — when millions more people are identified as having pre-diabetes, mild hypertension, or borderline cholesterol, where do they go? What kind of follow-up support exists for them? In many cases, the answer is little to none. The system simply isn't equipped to provide comprehensive care for the newly diagnosed, especially in a climate of limited resources and rising demand.

There's also a risk that these screenings become performative — a way for policymakers to appear proactive without actually changing outcomes. A health MOT might be widely advertised, but unless there is real investment in services to support lifestyle changes, it remains just another empty promise.

The Deeper Issue: Inequality and Its Consequences

England's most disadvantaged communities face a health gap of nearly 19 years less healthy life expectancy compared to the least disadvantaged. That statistic isn't just about individual habits — it's a reflection of deep-seated social inequities.

It is in this context that we must reframe our understanding of prevention. True prevention means not only detecting health risks but ensuring that people have the conditions and support necessary to live well. That requires investment in affordable housing, better education systems, mental health services, and job creation — all things that sit outside the traditional purview of medicine.

If we are serious about public health, then we must start thinking like social policymakers, not just medical professionals. We need to move beyond talking about health as a personal responsibility and begin discussing it as a collective societal investment.

What We're Really Talking About

In short, screening is an essential tool — but only when paired with the infrastructure and support to act on those findings. A health MOT may be a step in the right direction, but if we stop there, we're merely documenting a crisis without solving it.

I have sympathy for Devi Sridhar's efforts to promote early intervention. However, the next step must involve meaningful engagement with social policy — not just another set of guidelines or checklists. If we want to reduce health inequalities and build a truly preventative healthcare system, we must begin by addressing the upstream factors that determine health outcomes.

Otherwise, all our screening efforts will amount to little more than window dressing on a deeply flawed system.
