Systolic Blood Pressure and Socioeconomic Status in a large multi-study population.

ABSTRACT: The present study used harmonized data from eight studies (N?=?28,891) to examine the association between socioeconomic status (SES) and resting systolic blood pressure (SBP). The study replicates and extends our prior work on this topic by examining potential moderation of this association by race and gender. We also examined the extent to which body mass index (BMI), waist circumference (WC), and smoking might explain the association between SES and SBP. Data were available from six race/gender groups: 9200 Black women; 2337 Black men; 7248 White women; 6519 White men; 2950 Hispanic women; and 637 Hispanic men. Multivariable regression models showed that greater annual household income was associated with lower SBP in all groups except Hispanic men. The magnitude and form of this negative association differed across groups, with White women showing the strongest linear negative association. Among Black men and Hispanic women, the association was curvilinear: relatively flat among lower income levels, but then negative among higher income ranges. Education also was independently, negatively related to SBP, though evidence was weaker for race and gender differences in the strength of the association. Higher BMI and WC were associated with higher SBP, and current smoking with lower SBP. Inclusion of these risk factors resulted in only a modest change in the magnitude of the SBP and SES relation, accounting on average about 0.4?mmHg of the effect of income and 0.2?mmHg of the effect of education-effects unlikely to be clinically significant. Further understanding of mechanisms underlying the association between SBP and SES may improve risk stratification in clinical settings and potentially inform interventions aimed at reductions in social disparities in health.

Project description:Study objectivesPositive airway pressure (PAP) treatment of obstructive sleep apnea reduces blood pressure (BP). Retrospective data suggest that African Americans (AA), a group at high-risk for hypertensive organ dysfunction, may have a greater BP response to PAP therapy than European Americans (EA). We examined the difference in 24-hour BP response to 3 months of PAP treatment between AA and EA.MethodsParticipants (n = 259, 161 AA and 98 EA) with apnea-hypopnea index ≥ 15 events/h from 2 prospective cohorts were included. t-Tests and multiple linear regression were used to examine BP outcomes in AA vs EA, adjusting for PAP adherence, socioeconomic status, and baseline characteristics.ResultsParticipants were middle aged (mean ± SD, 53.8 ± 9.3 years), 86% (227) men, apnea-hypopnea index 35.6 ± 19.2 events/h, and PAP adherence of 3.36 ± 2.24 h/day. The reductions in 24-hour systolic and diastolic BP (mm Hg) were not different in AA vs EA (systolic = -1.13 ± 12.1 vs -0.61 ± 12.8, P = .80 and diastolic = -0.74 ± 7.9 vs -0.80 ± 7.4, P = .96), and race was not a predictor of 24-hour systolic or diastolic BP reduction (P = .75 and 0.54). Socioeconomic status and PAP adherence demonstrated a significant interaction; low socioeconomic status was associated with an increase in 24-hour systolic BP (β = 19.3, P = .03) in the absence of PAP use but a greater reduction in 24-hour systolic BP with higher PAP adherence (β = -3.96, P = .03).ConclusionsTwenty-four hour BP response to PAP treatment is similar in AA and EA. Adherence to PAP treatment is more effective in improving 24-hour systolic BP in those with low SES.Clinical trial registrationRegistry: ClinicalTrials.gov; Name: Race and CPAP Effectiveness (RACE); URL: https://clinicaltrials.gov/ct2/show/NCT01960465; Identifier: NCT01960465 and Registry: ClinicalTrials.gov; Name: The Effects of Treating Obese and Lean Patients with Sleep Apnea (PISA); URL: https://clinicaltrials.gov/ct2/show/NCT01578031; Identifier: NCT01578031.CitationImayama I, Gupta A, Yen PS, et al.
