The BBC's Rachel Ellison: "Even more women don't want children"

Health and relationships are being ignored in favour of a "male model" of success with all its damaging and dysfunctional aspects, says the Bread for Life health campaign.

Drinking levels for women are rising

"The gender gap in health, currently in women's favour, is closing as women inherit some of the adverse costs of the unhealthy and stressful lifestyles traditionally lived by men," warned Helen Wilkinson, a member of the Demos Advisory Council think-tank.

Drinking more

The report shows 51% of young women in the UK, compared to 37% of young men, are likely to forego a healthy lifestyle for their career, often skipping meals, neglecting exercise and drinking and smoking heavily.

Drinking levels for women are rising, with women in full-time jobs twice as likely to exceed sensible limits as those who do not work or work part-time.

Helen Wilkinson: "Need to define success more holistically"

Ms Wilkinson, author of No Turning Back: generations and genderquake, said: "The desire and drive for success on male terms means that women are increasingly mimicking male dysfunctions particularly in relation to erratic and unhealthy eating patterns."

She added: "We need to challenge the idea that hectic lifestyles are glamorous and an indicator of our success.

Sleeping with the boss

"We need to say that success and power achieved at the expense of mental and physical well-being and underpinned by unhealthy eating habits is not a sustainable model."

The research also revealed that 13% of young people of both sexes aged 18-24 would sleep with their boss if it gave them a chance of promotion.

Nearly one in five said they would do something morally or ethically wrong to win a better job.

Seven out of 10 are shown to define success by wealth and career, with one in five believing a career or attaining qualifications is more important to life than family and relationships.

"The research findings highlight an urgent need for young people to define success more holistically - a definition which takes self-nurture as its starting point," said Ms Wilkinson.
