Abstract Subject headings

We tested whether plasma levels of leptin and insulin are associated with the lower blood pressure in women of Peruvian Indian heritage compared with Caucasian women. A total of 181 women from Peru and 85 from Sweden, aged 20 to 60 years, with normal plasma glucose levels participated in the study. Measurements of anthropometry, blood pressure, and blood tests were performed after overnight fasting. Compared with women from Umeå in Sweden, women from Lima, Peru had higher body mass index (BMI) (26.2 +/- 4.9 v 24.4 +/- 3.8 kg/m(2)), waist circumference (85 +/- 11 v 79 +/- 10 cm), lower systolic blood pressure (99 +/- 15 v 114 +/- 14 mm; P <.001) and diastolic blood pressure (67 +/- 7 v 74 +/- 10 mm; P <.001). In addition, they had a reduction of the ratio of plasma leptin to BMI (0.52 +/- 0.22 v 0.61 +/- 0.36; P <.001), greater plasma insulin (80 +/- 42 v 41 +/- 21 pmol/L), but lower plasma glucose (4.2 +/- 0.5 v 5.1 +/- 0.5 mmol/L; P <.001). Furthermore, the 181 women from Lima had higher plasma triglyceride levels (1.5 +/- 0.8 v 1.3 +/- 0.7; P =.039), but lower plasma high-density lipoprotein (HDL)-cholesterol (1.0 +/- 0.2 v 1.5 +/- 0.4 mmol/L; P <.001) and total plasma cholesterol (5.0 +/- 1.1 v 5.9 +/- 1.3 mmol/L; P <.001) levels. Plasma leptin correlated with blood pressure and BMI in both populations (P <.001). In multiple regression analysis, BMI, but not log leptin, emerged as the determinant for systolic blood pressure. We concluded that women living in Lima have significant lower blood pressure levels in association with elevated plasma insulin concentrations, but lower plasma leptin values adjusted for BMI in comparison with women from northern Sweden. This may suggest that the concept of metabolic syndrome is different among women with Peruvian Indian heritage in comparison to a Caucasian population.
