Parents who share a bed with their breastfed baby could face a fivefold increase in the risk of crib death, even if the parents do not smoke, according to a new study. The research was led by the London School of Hygiene & Tropical Medicine and is published in BMJ Open.

Crib death -- also known as cot death or sudden infant death syndrome (SIDs) -- remains a major cause of death among babies under 1 year of age in high income countries. There is already a general consensus that sleeping with a baby increases the risk of cot death if the parents smoke or if the mother has been drinking alcohol or taking drugs. However, there are conflicting opinions as to whether bed sharing in general represents a risk when these factors are not present.

Some countries, including the US and the Netherlands, advise all parents against sharing a bed with their baby for the first 3 months. The UK currently only advises certain groups, including parents who are smokers, not to bed share.

The new study is the largest ever analysis of its kind. Researchers examined the individual records of 1,472 cot death cases and 4,679 control cases across five major studies. They found that the risk of cot death among breastfed babies under 3 months increased with bed sharing, even when the parents did not smoke and the mother had not consumed alcohol or drugs. This fivefold increase was in comparison to room sharing, where a baby slept in a cot in the parents' room.

The researchers estimate that 81% of cot deaths among babies under 3 months with no other risk factors could be prevented if they did not sleep in the same bed as their parents. The study also showed that the risk associated with bed sharing decreases as a baby gets older, and that the peak period for instances of cot death was between 7 and 10 weeks.

Professor Bob Carpenter from the London School of Hygiene & Tropical Medicine who was lead author on the study said: "Currently in the UK more than half of cot deaths occur while a baby is sleeping in the same bed as its parents. Although it is clear that smoking and drinking greatly increase the risk of cot death while bed sharing, our study shows that there is in fact an increased risk for all babies under 3 months who bed share, even if their parents do not smoke or drink.

"If parents were made aware of the risks of sleeping with their baby, and room sharing was instead promoted in the same way that the 'Back to Sleep' campaign was promoted 20 years ago to advise parents to place their newborn infants to sleep on their backs, we could achieve a substantial reduction in cot death rates in the UK. Annually there are around 300 cot death cases in babies under a year old in the UK, and this advice could save the lives of up to 40% of those. Health professionals need to make a definite stand against all bed sharing, especially for babies under 3 months."

The authors state that babies can still be brought into the parents' bed for comfort and feeding during the night, but that they should be placed in a cot next to the parents' bed to sleep.

Gilead's $1000-a-Pill Drug Could Cure Hep C in HIV-Positive People

Gilead's $1000-a-Pill Drug Could Cure Hep C in HIV-Positive People

TheStreet (July 21, 2014) New research shows Gilead Science's drug Sovaldi helps in curing hepatitis C in those who suffer from HIV. In a medical study, the combination of Gilead's Hep C drug with anti-viral drug Ribavirin cured 76% of HIV-positive patients suffering from the most common hepatitis C strain. Hepatitis C and related complications have been a top cause of death in HIV-positive patients. Typical medication used to treat the disease, including interferon proteins, tended to react badly with HIV drugs. However, Sovaldi's %1,000-a-pill price tag could limit the number of patients able to access the treatment. TheStreet's Keris Lahiff reports from New York. Video provided by TheStreet
