[Body fat distribution, blood pressure and plasma lipids and lipoprotein levels]
1Centro de Educação Física e Desporto, Universidade Estadual de Londrina, PR.
Purpose:
To study associations between FAT distribution and blood pressure levels and concentrations of lipids and lipoproteins, irrespective of body fat content and physical activity.
Methods:
A sample of 62 subjects of both genders aging 20-45 years-old was used in the study. The adipose tissue distribution was based on the waist-to-hip ratio (WHR). Body fat content was estimated by the body mass index (BMI), and physical activity was assessed by maximal oxygen uptake (VO2max). Partial correlation analyses were used to determine the strength of the associations.
Results:
After correction for BMI there was a significant partial correlation between centripetal adipose tissue distribution and serum triglyceride, LDL-cholesterol levels, and blood pressure. However, controlling for VO2max, there was no significant association between WHR and any serum variable and blood pressure.
Conclusion:
The centripetal adipose tissue distribution, independent of body fat content, was related to lipid and lipoprotein plasma concentrations and to blood pressure levels in both sexes. Physical activity seems to be an important modifier of this relationship, emphasizing its role in the control of cardiovascular risk factors.
