A Statistics Canada report indicates that reported cases of diabetes among Canadians aged 12 years or older increased from 5.8% in 2007 to 6.5% in 2012; and in 2012, 14.7% of obese Canadians 18 years or older had diabetes compared with 5.1% of those who were not obese. In view of the potential health and wellness benefit of weight loss to obese diabetic patients, this report aims to provide current evidence on the clinical effectiveness of various obesity management interventions that could be used in primary care settings to halt or slow the progression of type 2 diabetes.

Disclaimer: The Rapid Response Service is an information service for those involved in planning and providing health care in Canada. Rapid responses are based on a limited literature search and are not comprehensive, systematic reviews. The intent is to provide a list of sources of the best evidence on the topic that CADTH could identify using all reasonable efforts within the time allowed. Rapid responses should be considered along with other types of information and health care considerations. The information included in this response is not intended to replace professional medical advice, nor should it be construed as a recommendation for or against the use of a particular health technology. Readers are also cautioned that a lack of good quality evidence does not necessarily mean a lack of effectiveness particularly in the case of new and emerging health technologies, for which little information can be found, but which may in future prove to be effective. While CADTH has taken care in the preparation of the report to ensure that its contents are accurate, complete and up to date, CADTH does not make any guarantee to that effect.
