The NHS should consider checking pregnant women's vitamin D levels to protect babies from the "Victorian" bone disease rickets, an expert says.
A Journal of Medical Screening article suggests rickets was returning, with many women not getting enough vitamin D, which comes mainly from sunlight.
A consultant paediatrician at Ealing's hospital, Dr Colin Michie, says the increased use of high-factor sun-cream means a lot of women who are not in at-risk groups are also vitamin D deficient.
He says the idea of screening is interesting, but he argues that providing free vitamin D supplements for all pregnant women would be cheaper and easier.
He believes this would lead to healthier babies and would save the NHS money.
