May Measurement Month 2019: an analysis of blood pressure screening results from Colombia.

Hypertension awareness and control is poor in low- and middle-income countries. Thus, implementing strategies to increase hypertension detection is needed. Colombia participated as one of the 92 countries involved in the third campaign of the May Measurement Month in 2019. Blood pressure (BP) was measured in 48 324 volunteers from 13 departments in Colombia. In total, 27.9% individuals were identified with hypertension. Of those with hypertension, 63.7% were aware of their condition, 60.0% were on antihypertensive medication, and 38.4% had controlled BP. These results showed low levels of awareness, treatment, and control of hypertension in this sample of subjects volunteered to participate, suggest the urgent necessity of implementing programmes to improve the diagnosis and management of hypertension in Colombia.

Ethnic Differences in the Prevalence of Hypertension in Colombia: Association With Education Level.

BACKGROUND: A higher prevalence of hypertension is reported among Afro-descendants compared with other ethnic groups in high-income countries; however, there is a paucity of information in low- and medium-income countries. METHODS: We evaluated 3,745 adults from 3 ethnic groups (552 White, 2,746 Mestizos, 447 Afro-descendants) enrolled in the prospective population-based cohort study (PURE)-Colombia. We assessed associations between anthropometric, socioeconomic, behavioral factors, and hypertension. RESULTS: The overall prevalence of hypertension was 39.2% and was higher in Afro-descendants (46.3%) than in Mestizos (37.6%) and Whites (41.5%), differences that were due to the higher prevalence in Afro-descendant women. Hypertension was associated with older age, increased body mass index, waist circumference and waist-to-hip ratio, independent of ethnicity. Low education was associated with hypertension in all ethnic groups, and particularly in Afro-descendants, for whom it was the factor with the strongest association with prevalence. Notably, 70% of Afro-descendants had a low level of education, compared with 52% of Whites-26% of Whites were university graduates while only 7% of Afro-descendants were. We did not find that education level alone had a mediator effect, suggesting that it is not a causal risk factor for hypertension but is an indicator of socioeconomic status, itself an important determinant of hypertension prevalence. CONCLUSIONS: We found that a higher prevalence of hypertension in Colombian Afro-descendants than other ethnic groups. This was principally associated with their lower mean educational level, an indicator of lower socioeconomic status.

Epidemiology of Hypertension and Diabetes Mellitus in Latin America.

Hypertension and type 2 diabetes mellitus are two important risk factors that contribute to cardiovascular diseases worldwide. In Latin America, hypertension prevalence varies from 30 to 50%. Moreover, the proportion of awareness, treatment and control of hypertension is very low. The prevalence of type 2 diabetes mellitus varies from 8 to 13% and around 40% of patients are unaware of their condition. In addition, the prevalence of prediabetes varies from 6 to 14% and this condition has also been associated with increased risk of cardiovascular diseases. The principal factors linked to a higher risk of hypertension in Latin America are increased adiposity, low muscle strength, unhealthy diet, low physical activity and low education. Besides being chronic conditions, leading causes of cardiovascular mortality, both hypertension and type 2 diabetes mellitus, represent a substantial cost for the weak health systems of Latin American countries. Therefore, it is necessary to implement and reinforce public health programs to improve awareness, treatment and control of hypertension and type 2 diabetes mellitus, in order to reach the mandate of the United Nations to decrease the premature mortality for CVD.
