[The Metabolic syndrome and metabolic characteristics in blood donors]

Abstract

Introduction: Metabolic syndrome (MS) is associated with increased cardiovascular risk. Blood donors are an apparently healthy population in which certain cardiometabolic characteristics are not evaluated in their selection, and there is limited information on their presence.

Aim: To determine the frequency of metabolic syndrome and its metabolic characteristics in blood donors. Materials and methods: Cross-sectional study was carried in a population of 244 blood donors between 18 and 55 years of age who attended the Hemotherapy and Blood Bank Service of the Cayetano Heredia Hospital in Lima, Perú during the month of May 2023. The diagnosis of MS was made according to the Adult Treatment Panel III (ATP III) criteria. A bivariate analysis was performed between MS and metabolic characteristics with sex and a significance level of 5% was considered.

Results: 63.9% of blood donors were male. 43.6% of the population had MS. The most frequent characteristics found were hypertriglyceridemia (54.5%), abdominal obesity (51.2%) and high-density lipoprotein (HDL) low (48.8%). The age range of 40 to 49 years presented the highest frequency of MS (14.3%). Hypertriglyceridemia and high blood pressure were associated with male sex (p=0.003 and p=0.019 respectively), while low HDL was associated with female sex (p<0.001).

Conclusions: Blood donors present an elevated frequency of MS. The detection of MS in apparently healthy populations as part of primary care could allow the formulation of strategies for early detection of cardiovascular risk factors.
