FASCE H, Eduardo et al. Relation of abdominal circumference and socio-economic status to blood pressure. Rev Chil Cardiol [online]. 2010, vol.29, n.1, pp.11-18. ISSN 0718-8560.

Aim: To correlate abdominal circumference (AC) and socio-economic status with blood pressure( BP) in an urban community of Concepción, Chile Methods: AC was measured in 8472 subjects above 15years of age, stratified by age, gender and socio-economic status. BP was measured by standard procedures, with a repeat recording when the initial valué was > 140/90mmHg. BP was compared in quartiles of abdominal circumference and according to socio-economic status. Pearson "r" was used to correlate BP and AC Results: Cut points for quartiles of AC were 78, 87, and 96 cm. Prevalence of hypertension in high, médium and low socio-economic status was 17.9%, 19.5% and 24.5%, respectively Mean systolic BP was 112 - 109 mmHg (males - females) in the first AC quartile, 118 - 118, 123-122 and 129-129 in the second, third and fourth quartiles, respectively. A significant correlation between AC and BP (systolic and diastolic) was observed in both genders (r 0.345 and 0.281 for males and females, respectively, p<0.00001). 22% of low socio-economic subjects belonged in the first AC quartile compared to 28.8% in the 4th quartile. In contrast 38.9% of high socio-economic subjects belonged in the first AC quartile while 15.5% did so in the 4th quartile (p<0001). Conclusion: A positive correlation ofAC and blood pressure was shown in both genders. A greater AC in low socio-economic subjects maybe related to a higher prevalence of hypertension in this group.
