Increased waist circumference and risk of diabetes

Abstract

Increased waist circumference is a cardiovascular risk factor. Currently the cutoffs are those that are in accordance with the International Diabetes Federation (IDF) or with Latin American standards; there are no studies in Colombian population showing the relationship between increased waist circumference and the risk of diabetes. This study aims an approach to show the relationship between increased waist circumference by IDF or Latin American criteria and the risk of diabetes.

Methodology: cross-sectional study where multivariate analysis was performed using two models: increased waist circumference by IDF criteria and waist circumference by Latin American standards and risk of diabetes, adjusted for age, sex, HDL cholesterol and body mass index (variables significant in univariate analysis).

Results: 2200 patients were included. 30.45% (670 patients) have type 2 diabetes; of these, 90.72% have increased waist circumference by IDF criteria, 76.65% by Latin American standards. Model 1 was found as independent factors associated with diabetes: male OR = 1.30 (95% CI 1.05 -1.6, p = 0.014) and increased waist circumference by IDF criteria OR = 1.44 (95% CI 1.02 - 2.04 p = 0.038); HDL cholesterol OR = 0.97 (95% CI from 0.96 to 0.98, p <0.001) was observed as protective factor. In model 2 were found: Male Sex OR = 1.31 (95% CI 1.06 -1.61, p = 0.01) and increased waist circumference by Latin American standards OR = 1.42 (95% CI 1.12-1.79, p = 0.003); HDL cholesterol OR = 0.97 (95% CI from 0.96 to 0.98, p <0.001) was observed as protective factor.

Conclusion: the perimeter increased by IDF or by Latin American criteria appear to be associated independently with the risk of diabetes in Colombian population
