ABSTRACT
BACKGROUND:
Nighttime BP and BP dipping (daytime-nighttime BP) are prognostic for cardiovascular disease. Compared with other racial/ethnic groups, Black Americans exhibit elevated nighttime BP and attenuated BP dipping. Neighborhood deprivation may contribute to disparities in cardiovascular health, but its effects on resting and ambulatory BP patterns in young adults is unclear. Therefore, we examined associations between neighborhood deprivation with resting and nighttime BP and BP dipping in young Black and White adults.METHODS:
We recruited 19 Black and 28 White participants (23 M/24 F, 21±1 years, body mass index 26±4 kg/m2) for 24-hour ambulatory BP monitoring. We assessed resting BP, nighttime BP, and BP dipping (absolute dip and nighttimedaytime BP ratio). We used the area deprivation index (ADI) to assess average neighborhood deprivation during early- and mid-childhood, and adolescence.RESULTS:
Compared with White participants, Black participants exhibited higher resting systolic and diastolic BP (ps≤0.029), nighttime systolic BP (114±9 vs. 108±9 mmHg, p=0.049), diastolic BP (63±8 vs. 57±7 mmHg, p=0.010), and attenuated absolute systolic BP dipping (12±5 vs. 9±7 mmHg, p=0.050). Black participants experienced greater average ADI scores compared with White participants (110(10) vs. 97(22), p=0.002), and select ADI scores correlated with resting BP and some ambulatory BP measures. Within each race, select ADI scores correlated with some BP measures for Black participants, but there were no ADI and BP correlations for White participants.CONCLUSIONS:
Our findings suggest neighborhood deprivation may contribute to higher resting BP and impaired ambulatory BP patterns in young adults warranting further investigation in larger cohorts.
