ABSTRACT

BACKGROUND AND OBJECTIVES: In patients with type 2 diabetes mellitus (DM2), the presence of increased waist circumference and triglycerides is a reflection of increased visceral fat and insulin resistance. However, information about the prevalence and clinical characteristics of the hypertriglyceridemic waist (HTGW) phenotype in patients with DM2 is scarce. The aim of the present study was to analyze the prevalence and characteristics of DM2 patients with HTGW.

METHODS: We analyzed 4214 patients with DM2 in this epidemiological, cross-sectional study conducted in primary care centers across Spain between 2011 and 2012. The HTGW phenotype was defined as increased waist circumference according to the International Diabetes Federation criteria for Europids (≥ 94 cm for men and ≥ 80 cm for women) with the presence of triglyceride levels ≥ 150 mg/dL. We compared the demographic, clinical and analytical variables according to the presence or absence of the HTGW phenotype.

RESULTS: Thirty-five percent of patients presented the HTGW phenotype. Patients with the HTGW phenotype had a higher body mass index (31.14 ± 4.88 vs. 29.2 ± 4.82 kg/m2; p < .001) and glycated hemoglobin levels (7.38 ± 1.2% vs. 7 ± 1.07%; p < .001). The presence of hypertension, peripheral arterial disease, cardiac insufficiency and microvascular complications were higher when compared with patients without the HTGW phenotype. Patients with the HTGW phenotype were less adherent to prescribed diet (69.8 vs. 81%; p < .001), exercise (44.6 vs. 58.2%; p < .001) and presented greater weight increase within the year prior to the study visit (29.4 vs. 22.5%; p < .001).

CONCLUSIONS: The HTGW phenotype is prevalent in the Spanish DM2 population and identifies a subgroup of patients with higher cardiometabolic risk and prevalence of diabetic complications.
