Effect of caloric restriction with or without physical activity on body composition and epicardial fat in type 2 diabetic patients: A pilot randomized controlled trial.

Background And Aims: There is debate over the independent and combined effects of caloric restriction (CR) and physical activity (PA) on reduction in fat mass and in epicardial fat thickness. We compared the impact of a similar energy deficit prescription by CR or by CR combined with PA on total fat mass, epicardial fat thickness, and cardiometabolic profile in individuals with type 2 diabetes.

Methods And Results: In this 16-week randomized controlled study, 73 individuals were randomly enrolled to receive: 1) a monthly motivational phone call (Control), 2) a caloric deficit of -700 kilocalories/day (CR), or 3) a caloric deficit of -500 kilocalories/day combined with a PA program of -200 kilocalories/day (CR&PA).

Relative contribution of muscle and liver insulin resistance to dysglycemia in postmenopausal overweight and obese women: A MONET group study.

Objectives: The relative contribution of muscle and liver insulin resistance (IR) in the development of dysglycemia and metabolic abnormalities is difficult to establish. The present study aimed to investigate the relative contribution of muscle IR vs. liver IR to dysglycemia in non-diabetic overweight or obese postmenopausal women and to determine differences in body composition and cardiometabolic indicators associated with hepatic or muscle IR.

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).

Diagnosis of cystic fibrosis-related glucose abnormalities: Can we shorten the standard oral glucose tolerance test?

Adult patients with cystic fibrosis (APCF) are at high risk of developing impaired glucose tolerance (IGT) and CF-related diabetes (CFRD) and thus an annual screening with a 2-h oral glucose tolerance test (OGTT) is recommended. This population would greatly benefit from a simplified and harmless alternative to the standard OGTT. Thus, we aimed to compare the diagnostic values of HbA1c and glycemias at interval time points during the 2-h OGTT for IGT and CFRD detection in APCF.

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).

The Visceral Adiposity Index: Relationship with cardiometabolic risk factors in obese and overweight postmenopausal women--a MONET group study.

A recent study suggested visceral adipose index (VAI) as an indicator of adipose tissue distribution and function associated with cardiometabolic risk. We aim to examine the association between VAI and visceral adipose tissue (VAT), insulin sensitivity, and a large panel of associated cardiometabolic risk factors, and to determine if changes in VAI after weight loss intervention will reflect changes in VAT. We performed a secondary analysis using the data of 99 overweight and postmenopausal women that completed a 6-month weight loss program (Montreal Ottawa New Emerging Team Study).

Relationship between the body adiposity index and cardiometabolic risk factors in obese postmenopausal women.

Objective: The purpose of the present secondary analysis study was to investigate the ability of the body adiposity index (BAI) to detect changes in % body fat levels before and after a weight loss intervention when compared to % body fat levels measured using dual-energy X-ray absorptiometry (DXA) and to examine the relationship between the BAI with cardiometabolic risk factors.

Methods: The study population for this secondary analysis included 132 non-diabetic obese sedentary postmenopausal women (age: 57.2 ± 4.

Menopause and sarcopenia: A potential role for sex hormones.

Menopause is associated with a decline in estrogen levels, which could lead to an increase in visceral adiposity as well as a decrease in bone density, muscle mass and muscle strength. This decline in muscle mass, known as sarcopenia, is frequently observed in postmenopausal women. Potential causes of sarcopenia include age-related changes in the hormonal status, low levels of physical activity, reduced protein intake and increased oxidative stress.
