Objective:

To describe the prevalence of hypertension in Mexican adults, the proportion with controlled blood pressure (BP), and the trend in the 2018-2020 period.

Materials and methods:

BP was measured in 9 844 adults who participated in the National Health and Nutrition Survey (Ensanut, in Spanish) 2020. They were considered to have hypertension or BP controlled when adults met the Seventh Joint National Committee (JNC-7) or American Heart Association (AHA) criteria.

Results:

The prevalence of hypertension was 49.4% (according to AHA), of which 70.0% were unaware of their diagnosis. When using JNC-7 criteria, 30.2% of the adults had hypertension and 51.0% were unaware of your diagnosis. Among adults with a previous diagnosis of hypertension, 54.9% had controlled BP. Between the 2018-2020 period, no changes in prevalences were observed.

Conclusions:

At least a third of Mexican adults have hypertension and of them, at least half have not been diagnosed. The relevance of current hypertension diagnostic programs should be evaluated because underdiagnosis and poor control can lead to complications and death.
