About this study
The primary objective of the study is to identify baseline and early predictors of favorable and unfavorable response to lifestyle intervention. As a secondary objective, the investigators would like to validate our questionnaire or other identified predictors as clinical tools to guide us in selection of the most suitable candidates for lifestyle intervention programs. Assuming the same capacity of our questionnaire to predict an absence of weight loss (≥5%) or a loss to follow-up (likelihood ratio for a positive test, LR+ = 9.9), 70 subjects need to be included in this study in order to find a lower limit of the 95% confidence interval above 2.0 for this LR+, which is the limit of an acceptable test. The investigators will enroll participants with pre-diabetes and BMI 27-40 in our program and administer to them at baseline and at 3 months the designed questionnaire, as well as other already well validated questionnaires assessing state of change and readiness to implement diet or exercise modifications.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Lifestyle modification counsellingBehavioural
Patients meet individually every six weeks, a nurse or kinesiologist, and a dietitian (as well as a psychologist, if needed) and every three months an endocrinologist. A unique patient chart is shared by members of the interdisciplinary team, allowing sharing of the information and avoiding repetitions. Individualized behavioural intervention is proposed and focuses on attainable goals and progressive but sustained small changes in nutrition and physical activity. In addition, the participants have access to 24 weekly group seminars, on different aspects of excess weight and modification of lifestyle, to reinforce behaviour and commitment to lifestyle changes. Our approach meets all criteria suggested for clinical intervention in the 2006 Canadian clinical practice guidelines on the management and prevention of obesity in adults and children.

Questions about this trial
What is this clinical trial studying?

Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 13 Dec 2013. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
5% weight loss (time frame: 1 year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Dec 2013.
