Biochemical and nutritional factors associated with blood viscosity in adults living in a mountain chain, (Imbabura), Ecuador

Abstract:

The association of blood viscosity (BV) with hypertension and diabetes mellitus type 2 indicates that it should be considered, especially in populations living in mountain chains where the hemoglobin and hematocrit values are higher. In fact, this work analyzed the association of BV with nutritional and biochemical risk factors in the development of cardio metabolic diseases in healthy adults (20-60 years old; 46.39% female and 53.61% male) living in the urban Ecuadorian sierra. The body mass index (BMI) was calculated. The body fat percentage, body water percentage, waist circumference (WC) and blood pressure were measured. Determinations of biochemical and hematological parameters were performed using established methodologies and a validated formula was used to determine the BV. Hyperviscosity (HV) was present in 14.76% of the population: 10.46% men, 4.3% women. In this group, 42.8% showed metabolic syndrome (MS) against 33% in the normoviscosity group (NV). Uric acid (UA) was observed statistically higher in HV and NV with MS groups. A simple positive linear correlation was found between glucose (GLU) and triglycerides (TRI) concentrations and BV in HV without MS group. The multiple linear regression analysis indicated that GLU, UA and systolic pressure influence to increase BV in the HV without MS group. Glucose concentration and percentage of water, independently influence the BV in the NV without MS group. The increase in GLU and UA concentrations are the most influencing factors on BV in this population.
