Having a pet dog increases the risk of a baby growing into a snoring adult, a new study suggests.
A team led by scientists from Umea University Hospital in Sweden questioned more than 15,500 randomly selected people from Norway, Iceland, Denmark, Estonia and Sweden about their childhood and snoring habits.
Each participant was between 25 and 54 and were asked if any pets lived in their home when they were born or while they were growing up as a child.
Published in the online journal Respiratory Research, the study found that only dogs seemed to pose a snoring risk, making a 3.4 per cent contribution to the likelihood of it occurring in adult life.
A similar association was not seen for cats or other pets.
Other snoring risk factors were identified as growing up in a large family, recurrent childhood ear infections and being hospitalised for a chest infection before the age of two.
Habitual snoring is defined as "loud and disturbing snoring at least three nights a week", the Press Association notes and the BBC reports that snoring can also be a symptom of obstructive sleep apnoea.
