Old couple walking hand in hand

London - Men could be about to win the lifelong battle of the sexes – or at least draw even.

Experts say that adult males will soon have the same life expectancy as females for the first time since records began.

By the time today’s 12-year-old boys reach 30, they can expect to live to a month or so over 87 – matching the lifespan of the girls they are in school with today.

Younger boys in England and Wales might even outlive their female classmates, an adviser to the Office for National Statistics has predicted.

Traditionally, males are the weaker sex in terms of life expectancy, with boys more likely than girls to perish in the womb men dying earlier than women as adults. In Victorian times, the gap was relatively narrow but a steady increase in male smokers meant it widened to six years by 1970 – the biggest gap since records began in 1841.

Although the gap has since narrowed, other animal species show a similar discrepancy, and it had been assumed that underlying genetic factors left men condemned to an earlier grave. But Professor Leslie Mayhew, a statistician at City University, London, believes that the tide is turning.

He said that the shift away from macho lifestyles towards the healthier approach more traditionally favoured by women was bringing with it the gift of longer life.

Fewer men smoke, lung cancer rates have plummeted and heart attacks, while up to three times more common in men than in women, are much easier to treat than in the past. He told the Sunday Times: “There has been a huge decline in the numbers working in heavy industry; far fewer males smoke than before and there is much better treatment for heart disease, which tends to affect more males than females.”

Professor Mayhew’s research, to be published by City University’s Cass Business School, differs from the official forecast. The professor, who describes the trend as “well entrenched”, has worked out that a boy born in 2000 will, from the age of 30, have the same life expectancy as a girl of the same age.

But the Office for National Statistics estimates there will still be a gap of three and a half years. It insisted yesterday that many factors must be taken into account when making long-term projections and it is happy with its data.

Professor Mayhew’s calculations apply only from the age of 30 as baby boys are still expected to be more fragile than girls and young men are more likely to die in sporting and road accidents.

He says that the ONS is too cautious and men are catching up in other countries too. In Sweden, it will take only until 2024 for a 30-year-old man to have the same number of years ahead of him, on average, as a woman of the same age.

British women’s life expectancy is still on the rise, but at a slower rate than men’s. And higher rates of obesity in the female population could slow it further. Professor Mayhew’s predictions apply only to England and Wales. Scotland, where life expectancy is generally lower, is excluded from the calculations. - Daily Mail
