Key result
Between 1988 and 2004, hypertension prevalence in urban Chilean communities increased from 18.6% to 21.7%, while treatment rates increased from 35.6% to 59.9% and control from 7.5% to 30.7%.
Cross-Sectional (n=8,472)
Despite an increase in hypertension prevalence over 15 years in urban Chile, there were significant improvements in treatment and control rates.
Rising prevalence offset by gains in treatment and control in urban Chile warrants monitoring; leaves open drivers and generalizability.
OBJECTIVES: To evaluate the changes experienced over 15 years in the prevalence, state of awareness, treatment and control of hypertension, in urban communities of the VIII Region of Chile. METHODOLOGY: In order to ensure an objective analysis in comparison of the indicators, the methodological design used in 1988 was replicated: a representative, non-institutionalized sample, considering age, gender and socio-economic level. Blood pressure was measured using mercury manometers during two visits carried out on different days. Hypertension criteria: systolic blood pressure>or=140 mmHg and/or diastolic blood pressure>or=90 mmHg, or patients under treatment. RESULTS: A sample of 8472 residents was obtained, based on the previously defined stratification. Hypertension prevalence increased from 18.6% in 1988 to 21.7% in 2004. This occurred in all age groups and in both genders. The state of awareness remained stable: 66.9% in 1988 and 66.6% in 2004. The state of treatment increased from 35.6% (1988) to 59.9% (2004), and the state of hypertension control from 7.5 to 30.7%, respectively. CONCLUSION: This study demonstrated an increase in hypertension prevalence from 1988 to 2004. Meanwhile the state of awareness remained stable but there was a significant increase in the state of treatment and control, which were in accordance with public policies and changes in antihypertensive treatment.

H et al. (2007) conducted a cross-sectional in Hypertension (n=8,472). 2004 survey vs. 1988 survey was evaluated on Hypertension prevalence. Between 1988 and 2004, hypertension prevalence in urban Chilean communities increased from 18.6% to 21.7%, while treatment rates increased from 35.6% to 59.9% and control from 7.5% to 30.7%.
