Abstract

BACKGROUND: Socioeconomic status (SES) and ethnicity are both important determinants of hypertension prevalence and control rates but their separate contribution is unknown. We assessed the association of SES with hypertension prevalence, awareness, treatment and control, and whether this differs between ethnic groups. METHODS: We used baseline data from the Healthy Life in an Urban Setting (HELIUS) study, a multiethnic population-based cohort study, including 18 106 participants (84% of the total cohort) of Dutch (n = 4262), African Surinamese (n = 3732), Moroccan (n = 2902), Turkish (n = 2694), South-Asian Surinamese (n = 2664) and Ghanaian (n = 1947) descent with data on SES and hypertension status. RESULTS: Regardless of ethnicity, lower SES was associated with higher hypertension prevalence, especially in participants with no education compared with those with higher levels of education [OR 2.29 (2.05-2.56)]. There was an inverse association between SES and hypertension treatment with the strongest association for lower compared with higher educated participants [OR 1.63 (1.39-1.90)]. In addition, lower SES was associated with lower hypertension control with the strongest association for participants with the lowest compared with the highest occupational level [OR 0.76 (0.60-0.95)]. The association between educational level and treatment but not the other SES- or hypertension-indicators, was influenced by ethnicity, with lower educated Dutch and African Surinamese having higher ORs for hypertensive treatment [Dutch OR 1.98 (1.43-2.76); African Surinamese OR 1.44 (1.10-1.89)]. CONCLUSION: SES, in particular education, impacts hypertension treatment in the Netherlands, whereas the association of specific SES parameters with hypertension indicators differ across ethnic groups. Further exploration is needed on how sociocultural beliefs and behaviours may differentially affect blood pressure control across ethnic minority populations.
