Association between leisure-time physical activity and arterial stiffness in adults of the ELSA-Brasil study: a mediation analysis.

Objectives: We aimed at defining the direct and the mediated pathways for the association between leisure-time physical activity (LTPA) and carotid-to-femoral pulse wave velocity (cf-PWV), and also to identify whether these effects are influenced by sex and age.

Methods: Cross-sectional data from 13 718 adults (35-74 years) were obtained at the baseline of the ELSA-Brasil study. The cf-PWV was obtained by measuring the pulse transit time and the distance traveled by the pulse between the carotid and the femoral, as well as clinical and anthropometric parameters were measured.

Arterial stiffness in black adults from Angola and Brazil.

Ethnicity is an important determinant of blood pressure levels, being black individuals affected more than any other ethnic group. Arterial stiffening, an independent risk factor for hypertension, is also influenced by ethnicity. However, whether black individuals from different continents would have different patterns of arterial stiffening is still unknown.

Gender-specific determinants of blood pressure elevation in Angolan adults.

Background: Hypertension affects African-American adults more than any other ethnic group in the US. However, some of the black populations living outside Africa are well adapted to food and lifestyle. We aimed to describe the clinical characteristics underlying the gender-specific determinants of BP and the risk of hypertension in public-sector workers living in Angola.
