Waistlines of women are too big to be healthy, according to a new report.
Researchers from the charity Nuffield Health say overweight women risk an increased chance of heart disease, type 2 diabetes, infertility and cancer.
They found that the average waist measurement for women 84.9cm, compared with the healthy size of 80cm.
Data from more than 30,000 women was collected and it found that 57 per cent have a waist larger than the healthy size.
Researchers also said that 52.5 per cent of the women have a body mass indx in excess of the healthy range, while 16.2 per cent have scores which found they were moderately or morbidly obese.
Dr Davina Deniszczyc, professional head of physicians and diagnostics at Nuffield Health, said: "Whilst waist size may seem like a cosmetic issue, this isn't about women fitting into their skinny jeans. Rather, it's an important indicator of overall health and well-being, particularly when taken into account with other health measurements.
"The results for women highlight a worrying problem as fat being stored around the waist can contribute to significant health issues, such as breast cancer and infertility."
