Weight cycling and depressive symptoms in diabetes: a community-based study of adults with type 2 diabetes mellitus in Quebec.

Objective: The problems of obesity and depression in type 2 diabetes mellitus are well documented, yet the role of weight cycling in relation to these 2 chronic conditions has not been examined. The study objective was to determine whether weight cycling predicts the development of depressive symptoms in the course of 1 year.

Methods: A cohort study of 1100 adults with type 2 diabetes participating in the Diabetes Health and Well-Being Study (telephone survey using the random-digit-dialling method) had complete data at the 1-year follow up on depressive symptoms (Patient Health Questionnaire 9) and weight cycling frequency (going on a diet and losing >10 kg).

Changes in depressive symptoms and changes in lifestyle-related indicators: a 1-year follow-up study among adults with type 2 diabetes in Quebec.

Objective: The study purpose was to examine the association between changes in depressive symptoms and changes in lifestyle-related indicators among adults with type 2 diabetes.

Methods: A longitudinal survey was conducted among individuals with type 2 diabetes in Quebec. The sample consisted of 1183 subjects who responded to the baseline and 1-year follow-up telephone interviews, with complete data for depressive symptoms (Patient Health Questionnaire 9).

Types of smokers in a community sample of individuals with Type 2 diabetes: a latent class analysis.

Aims: Despite the detrimental effects of smoking on their health, a high number of adults with Type 2 diabetes continue to smoke. Identifying distinct types of smokers within this population could help tailor and target intervention programmes. This study examined whether smokers with Type 2 diabetes could be classified into different profiles based on smoking habits, socio-economic characteristics and lifestyle factors.

Factors associated with disability and depressive symptoms among individuals with diabetes: a community study in Quebec.

Background: The prevalence of diabetes in Canada is increasing. Multiple factors have been identified in the development of disability in diabetic patients, but the interaction of those risk factors is not clear.

Objective: The purpose of this paper was to assess the association between diabetes severity, health behavior, socioeconomic status, social support, depression, and disability simultaneously in a population-based study of individuals with diabetes in Quebec, Canada.

Reduction in serum apoB is associated with reduced inflammation and insulin resistance in post-menopausal women: A MONET study.

Objective: Large inter-individual variations exist in changes in inflammation and insulin resistance (IR) in response to hypocaloric-interventions in obese subjects that are not explained by weight-loss per se. We identified the number of serum apoB-lipoproteins (serum apoB) as the primary predictor of inflammatory markers in post-menopausal overweight/obese women. As apoB-lipoproteins are related to inflammation and inflammation promotes IR, we hypothesized that the reduction in inflammation and IR following hypocaloric-interventions is associated with the reduction in serum apoB.
