May measurement month 2017 campaign screening results from venezuela: An analysis of blood pressure, abdominal circumference and body mass index

Abstract

The present study had the purpose of evaluating the proportion of subjects with hypertension, treatment, control rates, and the relationship between blood pressure (BP) with body mass index and abdominal circumference in a cross-sectional study, as part of a worldwide study designed by International Society of Hypertension, performed during May 2017. After the protocol´s approval by the local Ethical Committee, 64 sites were included from eight Venezuelan regions. A short questionnaire was completed for each participant, including knowledge of taking antihypertensive treatment, diabetes, previous myocardial infarction or stroke, alcohol intake, and smoking. BP was measured in the sitting position three times after resting for 5 minutes, one minute apart, using mainly oscillometric devices. Height, weight and abdominal circumference were measured. Data analyses were performed by the MMM central team. 21644 individuals were screened. After multiple imputations, 10584 individuals [48.9% (50.7% male; 47.7% female)] had hypertension. Of subjects not receiving antihypertensive medication, 1538 (12.2%) were hypertensives. Of hypertensive individuals receiving antihypertensive medication, 2974 (32.9%) had uncontrolled BP. 15.6% of our sample had obesity according to their body mass index; 43.8% of women and 20.7% of men had abdominal obesity. BP was positively correlated with BMI and abdominal circumference. In this largest BP screening carried out in Venezuela, 48.9% of the individuals had elevated BP and 12.2% did not know that they had hypertension, and in one third of those with hypertension on treatment, BP was not controlled. 15.6% had obesity by BMI, and 35.1% abdominal obesity. Screening such as the MMM17 can evaluate the association between hypertension and obesity and therefore may help to inform control programs. © 2019, Instituto de Investigaciones Clinicas.
