Asociación entre diabetes mellitus y patología cardiovascular en la población adulta de Chile: Estudio de la Encuesta Nacional de Salud 2009-2010

Abstract

Background: Diabetes mellitus (DM) is a recognized atherosclerotic cardiovascular disease (ACVD) risk factor. This association has yet to be quantified in the Chilean population. Aim: To compare the frequency of ACVD between diabetic and non-diabetic Chilean subjects. Material and Methods: Data was extracted from the Chile National Health Survey (ENS) performed in 2009-2010. DM diagnosis was made with fasting glucose. ACVD (coronary, cerebral and peripheral vascular disease) was established by self-report. Major cardiovascular risk factors were identified by clinical and laboratory assessment. Results: A total of 5, 416 adults (2, 200 men and 3, 216 women) were surveyed in ENS 2009- 2010. Of these, 508 were diabetic and 375 reported ACVD. ACVD frequency was 16.1% and 6.1% in diabetic and non-diabetic subjects, respectively. In diabetic men, the frequency of ACVD steadily increased with age, from 5.1% to 22.1%. In diabetic women, the highest frequency of ACVD (17.4%) was found in ages ranging from 45 to 54 years. In people younger than 54 years, the odds ratio for ACVD in diabetic compared to non-diabetic subjects, was 3.59 in men (X2 = 4.03 p < 0.03) and 5.26 in women (X2 = 7.7 p < 0.007). Cardiovascular risk factors and metabolic syndrome were significantly more common in diabetic subjects with reported ACVD. Conclusions: DM is associated with an increased frequency of ACVD and cardiovascular risk factors in Chilean adults. In line with international reports, our findings suggest that DM is also a cardiovascular risk factor in Chile, particularly relevant for women.
