J Nephrol. 2008 Mar-Apr;21(2):197-204 Authors: Bossola M, Giungi S, Panocchia N, Vulpio C, Luciani G, Tazza L BACKGROUND: Being overweight and obesity are associated with improved survival in hemodialysis (HD) patients, based on mechanisms that are presently uncertain. We compared traditional and uremia-related cardiovascular risk factors in HD patients stratified according to their body mass index (BMI). METHODS: One hundred sixteen HD patients were stratified into 4 groups according to the BMI: underweight (<18.5), normal weight (18.5-24.9), overweight (25.0-29.9) and obese (> or =30). Blood samples were obtained before the HD session to measure serum albumin, high-sensitivity C-reactive protein, fibrinogen, ferritin, total cholesterol, LDL cholesterol, HDL cholesterol, apolipoprotein A-I and apolipoprotein B-100, apolipoprotein B (apoB) to apolipoprotein A (apoA) ratio and Lp(a) lipoprotein. RESULTS: There were 3 underweight (excluded from the analysis), 58 normal weight, 35 overweight and 20 obese patients. Their mean age was 62.1 +/- 14.1 years. There were 68 men and 45 women. Mean dialytic age was 5.32 +/- 3.2 years. The mean BMI of the study population was 25.2 +/- 4.1. The prevalence of smoking habit was similar in the 3 groups (17.2%, 8.5% and 25%, respectively; p=0.28). The prevalence of hypertension was higher in overwei ...
