Generation X health is worse in their fifties than baby boomers were at the same age, according to a major new study published on Wednesday 11 November 2026. Researchers at University College London found that people born in 1970 rated their health lower, and were more likely to be living with obesity and diabetes, than the generation before them.
The findings come from the UCL Centre for Longitudinal Studies, which analysed data from around 8,000 people born in England, Scotland and Wales during a single week in 1970. The participants, all taking part in the 1970 British Cohort Study, reported on their physical and mental health between 2021 and 2024, when they were in their early fifties.

Health matters most to Gen X — yet a quarter rate theirs poor or fair
The study found a striking contrast between what this generation values and how it feels. When participants rated the importance of different aspects of life on a scale of one to ten, health came out on top with an average score of 9.3, ahead of wealth and every other measure. Yet just two in five of the same people rated their own health as “excellent” or “very good”, while 26 per cent described it as “fair” or “poor”.
Around a third of the mid-lifers said they were living with obesity, while almost one in ten said they had been diagnosed with diabetes. The gap with the poorest households was sharp: 13 per cent of people in the lowest income group said they had diabetes, compared with 5 per cent of the wealthiest. Co-author Dr Vanessa Moulton, of the UCL Centre for Longitudinal Studies, said the study “reveals deep inequalities among gen X, with those from the lowest income households at greater risk of both physical and mental health difficulties”.
How Gen X compares with baby boomers at the same age
The researchers, whose findings were reported by The Times, compared the 1970-born group with baby boomers taking part in the 1958 National Child Development Study, who reached 50 in 2008. At the same age, half of the baby boomers rated their health as “excellent” or “very good”, against 41 per cent of Generation X. The boomers were also less likely to be living with obesity, at 26 per cent against 32 per cent, and less likely to have diabetes, at 6 per cent against 9 per cent.
The mental health picture followed the same pattern. Generation X participants were more likely than boomers to report a high number of symptoms of psychological distress. Among women, 26 per cent of the 1970 generation reported these problems, compared with 20 per cent of those born in 1958. More than a quarter of Gen X women reported symptoms of psychological distress, against 15 per cent of men in the same generation.
Professor George Ploubidis, co-author of the briefing paper and a professor at the UCL Centre for Longitudinal Studies, said the findings show “more members of gen X are in worse health in their early 50s than their baby boomer peers”. In explaining the physical health gap, he added that “obesity is a big part of the story”.
Why the gap matters for the NHS and for midlife Britain
Generation X, generally defined as people born between 1965 and 1980, is now moving through its fifties, the decade when long-term conditions such as type 2 diabetes and heart disease typically begin to appear. A generation arriving at that stage in poorer health than its parents were at the same age points to greater demand on GPs, hospitals and preventive services in the years ahead, and to more people managing chronic conditions while still in work.
The results also underline how much of the problem is preventable. Obesity and diabetes are closely linked, and both respond to weight, diet, activity and early treatment. The same week brought other evidence that aggressive treatment can reverse damage: a stronger cholesterol treatment shrank artery plaque by 21% in a new trial, showing that existing heart risk can be partly undone. For Generation X, the UCL findings are a warning issued while there is still time to act on it.
The study has limits that matter. Its health measures are self-reported by participants, and the comparison spans different eras, so the boomers’ 2008 experience and Gen X’s 2021–2024 experience reflect different diets, working lives and healthcare. The researchers present the findings as a population-level pattern, not a prediction about any one person, and the briefing paper is an initial set of findings from the cohort at age 51, with more analysis to follow.
What happens next for the 1970 cohort
The 1970 British Cohort Study has followed the same people since birth, and further sweeps will track how their health changes as they move through their fifties and towards retirement. The UCL team will also examine which factors — income, education, work, smoking, activity and diet — explain the largest share of the gap with the boomers.
For now, the message of the paper is plain. Generation X values its health more than anything else, yet arrives at midlife in measurably worse shape than the generation before it. Whether the NHS and public health policy respond with earlier checks, weight management and mental health support will shape how large that gap becomes by the time this generation reaches 60.
Frequently asked questions
Who counts as Generation X?
Generation X is generally defined as people born between 1965 and 1980. The UCL study followed people born in one week in 1970, placing them in the middle of that generation.
What did the UCL study actually measure?
It analysed self-reported physical and mental health from around 8,000 people in the 1970 British Cohort Study, collected between 2021 and 2024 when they were in their early fifties, and compared them with baby boomers from the 1958 National Child Development Study at age 50.
How much worse is Generation X health than baby boomers?
At the same age, 41% of Gen X rated their health excellent or very good, against 50% of boomers. Gen X had higher obesity (32% against 26%) and diabetes (9% against 6%), and more psychological distress, especially among women.
Why are Gen X women affected more?
More than a quarter of Gen X women (26%) reported symptoms of psychological distress, compared with 15% of men in the same generation and 20% of boomer women. The study reports the pattern but does not assign a single cause.
Does income make a difference?
Yes. Diabetes was reported by 13% of people in the poorest group, compared with 5% of the wealthiest, and the researchers found the lowest income households at greater risk of both physical and mental health difficulties.
Myth: feeling fine in your fifties means your health is fine.
High blood pressure, high cholesterol and type 2 diabetes often have no symptoms. The UCL figures are based on what people reported, and routine checks remain the main way these conditions are found early.
Myth: the health gap is just about getting older.
Both groups were compared at the same age, around 50, so the difference is generational rather than simply age. The researchers point to obesity as a major part of the explanation, alongside income inequality.
