Effect of Weight Loss and Lifestyle Changes on Vascular Inflammatory Markers in Obese Women

April 23, 2008 updated by: University of Campania "Luigi Vanvitelli"

Obesity is an independent risk factor for cardiovascular disease, which may be mediated by increased secretion of proinflammatory cytokines by adipose tissue.

To determine the effect of a program of changes in lifestyle designed to obtain a sustained reduction of body weight on markers of systemic vascular inflammation and insulin resistance.

Randomized single-blind trial conducted from February 1999 to February 2002 at a university hospital in Italy.

One hundred twenty premenopausal obese women (body mass index 30) aged 20 to 46 years without diabetes, hypertension, or hyperlipidemia.

The 60 women randomly assigned to the intervention group received detailed advice about how to achieve a reduction of weight of 10% or more through a low-energy Mediterranean-style diet and increased physical activity. The control group (n = 60) was given general information about healthy food choices and exercise.
