Short Term Effect of Smoking Cessation on Human Metabolism

Study Overview
=================
Brief Summary
-----------------
Investigating the short term smoking cessation on metabolism, examining of participant of smoking cessation workshops and former participants' file survey for metabolic aspects

Detailed Description
-----------------
Objective: To examine metabolic aspects occurring during the first 6-12 months following smoking cessation in participants of smoking cessation workshops. Design: A two armed study: prospective and retrospective. Prospective: Weight, BMI, waist circumference and waist: hip ratio were measured before, during and 6 months post cessation program. Retrospective: Blood test data for Blood fasting glucose (BFG) and lipid profile from the year preceding the workshops and the year after them were analyzed from participants' files. Smoking status was verified by phone conversation.
