Impact of the COVID-19 pandemic on blood pressure control: a nationwide home blood pressure monitoring study.

There are concerns that hypertension control may decrease during the COVID-19 pandemic. This study evaluated the impact of the COVID-19 pandemic on office blood pressure (OBP) and home blood pressure monitoring (HBPM) control in a large Brazilian nationwide sample. The results of an adjusted spline analysis evaluating the trajectory of OBP and HBPM control from 01/Jan/2019 to 31/Dec/2020 among independent participants who were untreated (n = 24,227) or treated (n = 27,699) with antihypertensive medications showed a modest and transient improvement in OBP control among treated individuals, which was restricted to the early months following the COVID-19 pandemic outbreak. Furthermore, slight reductions in OBP and HBPM values were detected in the early months following the COVID-19 pandemic outbreak among treated (n = 987) participants for whom blood pressure measurements before and during the pandemic were available, but not among untreated (n = 495) participants. In conclusion, we found no major adverse influence of the COVID-19 pandemic on OBP and HBPM control in a large nationwide sample.

Discrepancies in the diagnosis of hypertension in adolescents according to available office and home high blood pressure criteria.

This study aimed at comparing the prevalence of abnormal blood pressure (BP) phenotypes among 241 adolescents referred for hypertension (15.4 ± 1.4 years, 62% males, 40% obese) according to mostly used or available criteria for hypertension [AAP or ESH criteria for high office BP (OBP); Arsakeion or Goiânia schools' criteria for high home BP monitoring (HBPM)]. High OBP prevalence was greater when defined by AAP compared with ESH criteria (43.5% vs. 24.5%; p < .001), while high HBPM prevalence was similar between Arsakeion and Goiânia criteria (33.5% and 37.5%; p = .34). Fifty-five percent of the sample fulfilled at least one criterion for high BP, but only 31% of this subsample accomplished all four criteria. Regardless of the HBPM criteria, AAP thresholds were associated with lower prevalence of normotension and masked hypertension and greater prevalence of white-coat and sustained hypertension than ESH thresholds. These findings support the need to standardize the definition of hypertension among adolescents.
