Prevalence of metabolic syndrome and associated cardiovascular risk factors in Guatemalan school children

Abstract

Guatemala is experiencing a nutritional and lifestyle transition. While chronic malnutrition is prevalent, overweight, obesity and chronic diseases have increased substantially in the country. This study was conducted to investigate the prevalence of metabolic syndrome and the associated cardiovascular risk factors in the pre-adolescent Guatemalan population. A cross-sectional study was conducted among 302 Guatemalan children (8-13 years old) attending public and private schools in the Municipality of Chimaltenango. Demographic data and anthropometric and blood pressure measurements were collected. A blood sample was taken after an 8 h overnight fast and analyzed for glucose, triglyceride and high-density lipoprotein cholesterol levels. The data were analyzed to identify factors associated with metabolic syndrome and with its components. The prevalence of metabolic syndrome in the study population was 2.0 %. However, approximately 54 % of the children had at least one component of metabolic syndrome, while none had four or five of the components. The three most prevalent risk factors were high triglycerides (43.4 %), low HDL cholesterol (17.2 %) and obesity (12.3 %). Boys were more likely to be obese than girls and rural children were more likely to have higher triglyceride levels than urban children. Although the prevalence of metabolic syndrome is low, the fact that majority of the children already have at least one component of metabolic syndrome is cause for concern since components of metabolic syndrome can continue into adulthood and increase the risk for chronic diseases later in life. Therefore, immediate action should be taken to address the problem.
