Highlights from BARK’s Research Evidence Campaign on Pet Overweight/Obesity
Tuesday, August 24th, 2010This month, the BARK team finished a research evidence campaign on Pet overweight/obesity (see previous blog postings from June 22 and July 27). What we discovered in our analyses and literature searches probably won’t surprise you; however, the findings just further support that overweight/obesity is certainly a major health threat to our Pets.
Below, we listed a few of the highlights from our research, followed by a few questions to facilitate a discussion on these key findings. Tell us what you think, share your experiences, or let us know what questions you have and want to see answered concerning this growing epidemic.
From an exhaustive literature review on canine, feline and human overweight/obesity:
- Prevalence estimates of canine and feline obesity vary widely; between 22 to 44% in dogs and between 19 to 52% in cats. The prevalence of human obesity amongst adults doubled between 1980 and 2004
- The nature of the human-animal bond is very important. Dogs and cats are more likely to be of normal weight if owners use play as a reward instead of food and owners as overweight or obese cats and dogs tend to over-humanize their pets or use food as a substitute for affection
Study Results: Key factors associated with diagnosis of overweight or obesity in dogs and cats, from a study by the BARK team -
- Dogs are more likely to be diagnosed with overweight or obesity if they are female or neutered, or one of the following breeds: Labrador retriever, chihuahua, golden retriever, dachshund, beagle, pug, spaniel (both cocker spaniels and other spaniels), Yorkshire terrier, pomeranian, miniature pinshcer, jack russell terrier or pit bull breeds.
- Medium and small breed dogs were more likely to be overweight or obese than large breed dogs.
- Cats are more likely to be diagnosed with overweight or obesity if they are male or neutered. Mature adult cats (3-10 years of age) were more likely to be overweight or obese than young adult cats
- Cats that are of persian breed are less likely to be diagnosed as overweight or obese
- Dogs and cats with a greater number of hospital visits were less likely to be overweight or obese than dogs and cats with fewer visits (i.e., see their vet more often)
Significant findings from the Critically Appraised Topic (CAT) that researched the effectiveness of exercise and its role when treating overweight/obesity in both dogs and cats:
Overall finding: There is some evidence that exercise has a positive influence on the weight of dogs and cats, but there is limited evidence about the exact efficacy and the specific benefits are uncertain.
- The effectiveness of exercise and its role when treating overweight/obesity in dogs and cats is understudied.
- Several recent studies have shown promising advances in the ability to accurately record physical activity in dogs using accelerometers and/or pedometers. These developments will facilitate research into whether physical activity, either alone or as part of a weight loss program, is a beneficial exercise strategy for dogs and cats.
The results of these studies raised a number of questions for us and we’d love to have your input:
- There are a lot of explanations for the wide range of prevalence estimates and we feel that obesity is under diagnosed – how do you think we can address the under-diagnosis of overweight and obesity?
- Since prevention and/or maintenance of this disease largely deals with the owner’s own behaviors (e.g., controlled feeding, limited treats, daily exercise, etc.), what strategies do you use to address and manage the issue?
- As a veterinarian, do you communicate risk to educate your clients? What tactics do you use to help make them better informed decision makers, that may help modify their behaviors?
- As a veterinarian, do you think using accelerometers and/or pedometers could be a useful element in a weight loss program? If they were readily available, would you use them?
