ABSTRACT
BACKGROUND AND OBJECTIVES: Prehypertension is a new category of blood pressure and is considered a cardiovascular risk factor. This study has aimed to estimate the prevalence of prehypertension and the association between prehypertension and other vascular risk factors in young adults. MATERIAL AND METHODS: First year university students from all areas of study in the University of Cuenca were invited to participate. Prehypertension was defined as systolic blood pressure between 120-139 mmHg and/or diastolic blood pressure between 80-89 mmHg. Anthropometric, lipid and metabolic variables were measures. The presence of metabolic syndrome was evaluated and quantified based on the sum of the standardized scores of the waist circumference, the triglyceride/c-HDL ratio, mean blood pressure and R-HOMA (Index of insulin resistance to glucose lowering effect). RESULTS: A total of 545 university students were included in the analysis (mean age 20.36±3.9 years, 74.7% women). Prehypertension prevalence was 24% (95% CI: 21-27%), (56.5% in men and 13% in women). The condition of prehypertension was directly associated to the body mass index (OR: 1.194; 95% CI: 1.124-1.311), insulin resistance (R-HOMA, OR: 2.638; 95% CI: 1.263-4.926) and to the index or quantification of the severity of the metabolic syndrome (OR: 4-868; 95% CI: 3-846-8-328). On the other hand, HDL-c showed an inverse relationship with prehypertension (OR: 0.981; 95% CI: 0.957-0.993). CONCLUSIONS: One out of every four young adults presents prehypertension. This condition is associated to well-established vascular risk factors.
