According to the research, which has been carried out annually since 2006, the proportion of Brazilians diagnosed with hypertension increased over the past five years, from 21.6 percent in 2006 to 23.3 percent in 2010.

    The ministry also said that, to address the problem, the Brazilian government distributes free medicines to control blood pressure, since 80 percent of Brazilians who suffer from hypertension depend on the public health system.
