SERPA NETO, Ary et al. Impact of plasmatic lipids in glycemic control and its influence in the cardiometabolic risk in morbidly obese subjects. Arq Bras Endocrinol Metab [online]. 2009, vol.53, n.6, pp. 747-754. ISSN 1677-9487. http://dx.doi.org/10.1590/S0004-27302009000600009.
OBJECTIVES: To evaluate whether biochemical parameters are associated with a good glycemic control and to identify the occurrence of cardiometabolic risk variables. MATERIAL AND METHODS: One hundred forty Brazilians were evaluated. The subjects were characterized with regard to glycemic control as good, fair and poor and were divided into tertiles by TG and HbA1c. We use the ROC curve to determine which variables were predicted of poor glycemic control and the factor analyses to identify the domains that segregated among the risk variables. RESULTS: Fasting glucose and insulin levels, TG level, VLDL-C and HOMA-IR increased significantly across HbA1c tertiles. The best marker for identification of poor glycemic control was triglycerides. The presence of cardiometabolic abnormalities did not alter the glycemic control, but HOMA-IR was significantly higher in subjects with abnormalities. CONCLUSION: The use of TG levels offers a reasonable degree of clinical utility. In morbidly obese subjects insulin resistance is associated with individual cardiometabolic factors.
