The British Medical Journal, or BMJ, is one of the world's four leading comprehensive medical journals and the oldest.
150 years of history, the British Medical Journal has been welcomed by readers in many countries around the world for its academic rigour, novel content and lively typography.
every December, BMJ launches a special issue of The BMJ Christmas Issue.
as long as it is related to medicine, demonstrate method science, experimental data is true, no matter how open or even pointless research, can be published in this special issue.
BMJ Christmas special can also be seen as the "funny Nobel Prize" in medicine.
a study published in december's Christmas special, which looked at animals such as dogs, cats and miniature horses as complementary treatments to improve the mental health of patients or elderly people in nursing homes.
year's BMJ once again focused on animals, exploring the risk of diabetes in pets such as cats and dogs.
a team from the University of Upsana in Sweden conducted a team study that collected data on nearly 210,000 pairs of dogs and owners registered between 2004.01 and 2006.12, as well as more than 120,000 pairs of pet cats and owners.
follow-up period (2007.01-2012.12), the incidence of type 2 diabetes (T2DM) and the time of diagnosis of owners and their pets were recorded in detail.
, the owner's confirmed information comes from the National Register of Cases, the Coroner's Register and the Swedish Register of Prescription Drugs, while the pet's confirmed information comes from the Veterinary Care Insurance Database.
use the Weybull-Markov multi-state model for hazard ratio calculations.
Weybull-Markov multi-state model showed that the incidence of T2DM was 7.7/1000 and 7.9/1000 years for dog and cat owners during follow-up, respectively, compared with 1.3/1000 years for dogs and cats and 2.2/1000 cat years.
At the start of the study, the pets and their owners were middle-age, and after six years of follow-up, adjusted for other risk factors, data showed that owners of diabetic dogs had a 32 percent higher risk of developing T2DM than owners of healthy dogs.
, when dog owners had T2DM, dogs had a 28 percent increased risk of developing diabetes.
and the risk of diabetes in cats and owners did not show a clear trend.
and owners are at risk of developing T2DM during follow-up.
have lived with dogs for at least 15,000 years, and they share little by little of everyday life.
researchers believe that while the study did not obtain information about family lifestyle behaviors, it is speculated that the association may be due to the common risk of obesity associated with pets sharing lifestyles such as physical activity and eating habits with their owners.
, co-movement may be a key factor in explaining the differences between cats and dogs.
, the study showed that dogs and owners were associated with diabetes, while cats and owners were not.
