MONDAY, July 9 (HealthDay News) -- Babies who live with dogs and cats during their first year of life may be less susceptible to respiratory infections, such as the common cold, according to new research.
The study of nearly 400 children found that dogs were especially protective, and the babies who lived with dogs during their first year were about one-third more likely to be healthy during their first year, compared to babies who didn't have a pet in the home. Babies with dogs in the home were 44 percent less likely to develop an ear infection, and 29 percent less likely to need antibiotics than their petless peers.
"Children who had dog contacts at home were healthier and had less frequent ear infections and needed fewer courses of antibiotics than children who had no dog contacts," said the study's lead author, Dr. Eija Bergroth, a pediatrician who worked at Kuopio University Hospital, in Finland, at the time of the study.
Bergroth also noted that "cat contacts did not seem to have as strong of an impact on infection frequency in multivariate analysis as the dog contacts."
Results of the study, released online July 9, will be published in the August print issue of Pediatrics.
Previous research on pets in the home has suggested that animals, and dogs in particular, may provide some protection against the development of asthma and allergies. But, other studies have found that household pets may increase the number of respiratory infections in children, according to background information in the study.
To get a better idea of the impact of pets on a child's health, Bergroth and her colleagues reviewed data from a study of 208 children whose mothers were recruited during their last trimester of pregnancy. The mothers were from rural areas in Austria, Finland, France, Germany and Switzerland.
The study also included data from 216 mothers l
