Parents are being offered a way to predict the chances of their newborn baby becoming obese.
The online prediction is based on factors including the baby's birth weight, the body mass index (BMI) of its parents, and the number of people in the household.
Also taken into account are the mother's professional status and whether she smoked during pregnancy.
Researchers hope the formula will help identify infants at high risk of obesity, and assist families.
Childhood obesity is a leading cause of early type 2 diabetes and heart and circulatory disease, which is becoming more common in developed countries.
Around 17% of boys and 15% of girls aged two to 15 in England are now classified as obese, according to NHS figures.
Bmi's final flight has landed at Heathrow Airport after the firm was bought by British Airways.
With bmi Regional, bmibaby transferred to International Airlines Group ownership on completion of the purchase from Lufthansa.
IAG has consistently said that bmibaby and bmi Regional are not part of its long-term plans.
Uncertainty over the future of low-fare carrier bmibaby continues after the owner of British Airways completed its deal to buy BMI.
International Airlines Group (IAG), which owns BA and Iberia, will take on bmibaby and BMI Regional as part of its purchase agreement with Lufthansa but does not intend to keep the two businesses.
Announcing the completion of its purchase of loss-making BMI, IAG said it will run bmibaby and BMI Regional in the short-term while it looks at ways to exit the businesses.
Richard Hardy of the Prospect union, which represents engineers, said that the bmi takeover will have a particularly bad effect on the East Midlands.
General secretary of the pilots' union Balpa said:
International Airlines Group (IAG) - the parent company of British Airways - will be forced to give up a number of take-off and landing slots from Heathrow, as part of the bmi takeover. Routes to Nice, Cairo, Moscow and Edinburgh will be affected.
On gaining EC approval for the deal, IAG chief executive Willie Walsh said it was "great news for Britain" and also for British business and consumers.
The takeover has been bitterly opposed by Sir Richard Branson's airline, Virgin Atlantic, which has complained that the deal gives BA an over-strong presence at Heathrow.
The acquisition of bmi mainline will give British Airways an additional 56 average daily slots at Heathrow, of which up to 14 will be available to other carriers. Retained slots will be used to expand BA's operations at Heathrow with new destinations and more schedules.
Discussions with potential buyers for bmibaby and bmi Regional are continuing.
