“ Of all the forms of inequality, injustice in health care is the
most shocking and inhumane ”
Martin Luter King, 1966
In the context of cardiovascular health, some racial characteristics have been frequently associated with worse blood pressure (BP) control. For example, Black adults have more severe resistant hypertension as compared with other ethnic groups.11. Deere BP, Ferdinand KC. Hypertension and Race/Ethnicity. Curr Opin Cardiol. 2020;35(4):342-50. doi: 10.1097/HCO.0000000000000742.

A lot of this evidence has been gathered from populations where there had been little racial mixing and, for this reason, understanding the impact of specific racial characteristics of the Brazilian population on the occurrence, diagnosis, and control of hypertension is imperative.44.

The study by Sousa et al.66. Sousa CT, Ribeiro ALP, Barreto SM, Giatti L, Brant L, Lotufo P, et al. Racial Differences in Blood Pressure Control from Users of Antihypertensive Monotherapy: Results from the ELSA-Brasil Study. Arq Bras Cardiol. 2022; 118(3):614-622. provides a new perspective on the influence of race on the treatment and control of BP in Brazilian adults. Using a robust database of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil), the authors evaluated the association of self-reported race/skin color with BP control in individuals under different monotherapy antihypertensive regimens. This publication complements previous studies of the group on the influence of ethnicity on several aspects of hypertensive disease.77. Barber S, Diez Roux AV, Cardoso L, Santos S, Toste V, James S, et al. At the Intersection of Place, Race, and Health in Brazil: Residential Segregation and Cardio-Metabolic Risk Factors in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). Soc Sci Med. 2018;199:67-76. doi: 10.1016/j.socscimed.2017.05.047. , 88. Mendes PM, Nobre AA, Griep RH, Juvanhol LL, Barreto SM, Fonseca MJM, et al.

Black individuals using angiotensin-converting enzyme inhibitors (ACEI), angiotensin receptor blockers (ARBs), thiazide diuretics (TD) and beta blockers showed a worse BP control than White individuals. After statistical treatment of the data, the authors concluded that the differences in BP control between the racial groups could not be explained by a possible lower efficacy of ACEI and ARBs in Black patients. Despite the observational nature of the study, it starts to reveal some important topics about the management of hypertensive patients belonging to specific groups (in this case, Black population), and put forward some hypotheses that need to be investigated, mainly those related to racial health inequality and its repercussions.
Racial mixing, characteristic of the Brazilian population, raises important socioeconomical questions, and important challenges to health care in the country.44. Constante HM, Marinho GL, Bastos JL. The Door is Open, But Not Everyone May Enter: Racial Inequities in Healthcare Access Across three Brazilian Surveys. Cien Saude Colet. 2021;26(9):3981-0. doi: 10.1590/1413-81232021269.47412020. , 55.

Cien Saude Colet. 2021;26(9):4007-4019. doi: 10.1590/1413-81232021269.08092021. From the perspective of social determinants of health and disease processes, factors related to racial composition of the population (including racism) can contribute to health inequality, and thereby negatively influence the outcomes.11. Deere BP, Ferdinand KC. Hypertension and Race/Ethnicity. Curr Opin Cardiol. 2020;35(4):342-50. doi: 10.1097/HCO.0000000000000742. , 22. Ogunniyi MO, Commodore-Mensah Y, Ferdinand KC.

According to the 2019 Brazilian National Household Sample Survey (PNAD, Pesquisa Nacional por Amostra de Domicílios), 9.4% of respondents self-reported as Black, and 46.8% as Pardo .1111.

Also, we need to mention some features that strongly contribute to the management of chronic diseases in the Brazilian Unified Health System:1212. Castro MC, Massuda A, Almeida G, Menezes-Filho NA, Andrade MV, Noronha KVMS, et al. Brazil’s Unified Health System: The First 30 Years and Prospects for the Future. Lancet. 2019;394(10195):345-56. doi: 10.1016/S0140-6736(19)31243-7. the accelerated population aging and increasing social inequality, associated with the marked increase of chronic morbidities in our population (approximately 26 million people aged ≥ 50 years report more than two chronic conditions, where hypertension is present in most of them).1313. Nunes BP, Batista SRR, Andrade FB, Souza PRB Jr, Lima-Costa MF, Facchini LA. Multimorbidity: The Brazilian Longitudinal Study of Aging (ELSI-Brazil). Rev Saude Publica. 2018;52acc(Suppl 2):10s. doi: 10.11606/S1518-8787.2018052000637. There is also the increase in the incidence of all non-communicable diseases from 2013 to 2019, as reported in the Brazilian National Health Survey (PNS).44. Constante HM, Marinho GL, Bastos JL. The Door is Open, But Not Everyone May Enter: Racial Inequities in Healthcare Access Across three Brazilian Surveys. Cien Saude Colet. 2021;26(9):3981-0. doi: 10.1590/1413-81232021269.47412020.
In fact, data stratified by race/ethnicity from the 2019 PNS showed that Black and pardo individuals, mainly women (57.8%), reported worse health status. Besides, White people reported higher attendance at medical appointments than Black people, regardless of sex.44. Constante HM, Marinho GL, Bastos JL. The Door is Open, But Not Everyone May Enter: Racial Inequities in Healthcare Access Across three Brazilian Surveys. Cien Saude Colet. 2021;26(9):3981-0. doi: 10.1590/1413-81232021269.47412020. As compared with the 2013 PNS, a higher proportion of Black hypertensive patients who self-reported use of medications, performance of complementary tests and visits to specialists was found in the 2019 PNS. These patients also showed higher rates of attendance at medical care, especially in public services and primary health centers, although they were seen by different physicians at the last visit from the ones in previous consultations.55. Julião NA, Souza A, Guimarães RRM. Trends in the Prevalence of Systemic Arterial Hypertension and Health Care Service Use in Brazil Over a Decade (2008-2019). Cien Saude Colet. 2021;26(9):4007-4019. doi: 10.1590/1413-81232021269.08092021. Also, a Brazilian study showed that living in economically segregated neighborhoods, where Black and Pardo people are more likely to live, is associated with higher odds of hypertension (26%) and diabetes (50%) as compared with living in other areas. Thus, economically segregated neighborhoods may represent potential environment for promoting racial inequalities regarding the occurrence of cardiometabolic risk factors.77. Barber S, Diez Roux AV, Cardoso L, Santos S, Toste V, James S, et al. At the Intersection of Place, Race, and Health in Brazil: Residential Segregation and Cardio-Metabolic Risk Factors in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). Soc Sci Med. 2018;199:67-76. doi: 10.1016/j.socscimed.2017.05.047.
Therefore, extending the findings of Sousa et al.,66. Sousa CT, Ribeiro ALP, Barreto SM, Giatti L, Brant L, Lotufo P, et al. Racial Differences in Blood Pressure Control from Users of Antihypertensive Monotherapy: Results from the ELSA-Brasil Study. Arq Bras Cardiol. 2022; 118(3):614-622. the Brazilian population urgently calls for further studies that provide a wider perspective of care, from access to health services, medications, diagnostic tests, and specialists, to a longitudinal, coordinated multidisciplinary care and self-care strategies consistent with their socioeconomic, demographic and cultural characteristics.
