Impact of Socioeconomic Status on Blood Pressure Trends in Aging Populations
Exploring the link between socioeconomic factors and health outcomes, recent research sheds light on how financial status influences blood pressure variations among elderly individuals in China. Researchers found that lower socioeconomic status (SES)—measured through education, income, and job type—correlates with significant increases in blood pressure year over year. Particularly notable is that those without hypertension and with lower SES showed sharper increases in blood pressure, suggesting that economic stability plays a critical role in maintaining cardiovascular health as one ages.
The study utilized data from over 13,000 participants aged 65 and older, tracking their health across sixteen years. This extensive data allowed for a robust analysis of blood pressure changes over time, with particular focus on how different SES brackets experienced these changes differently. The findings underscore the need for targeted health interventions that consider economic background, aiming to reduce health disparities and improve outcomes for economically disadvantaged older adults.
Highlighting the importance of addressing socioeconomic inequalities in health care, the research advocates for more comprehensive strategies to manage and prevent hypertension in communities with lower SES. By integrating socioeconomic factors into public health planning, it is possible to better tailor interventions and ensure all older adults have the resources to manage their health effectively, thereby reducing the burden of hypertension and related health issues.

Associations between socioeconomic status and rates of blood pressure changes among Chinese older adults: a longitudinal community-based cohort study
Published in Public Health. Anna Shen et al.
Abstract
Objectives: The relationships between socioeconomic status (SES) and blood pressure changes among older adults in China remain unclear. This study aimed to examine the associations between SES and rates of blood pressure changes among Chinese older adults.
Study design: Community-based, prospective, longitudinal cohort study.
Methods: This study included 13,541 participants aged ≥65 years from the Chinese Longitudinal Healthy Longevity Survey between 2002 and 2018. SES was assessed by educational level, occupation, household yearly per capita income, and financial support. The estimated annual changes (EACs) of blood pressure were computed as the difference in blood pressure levels between any two adjacent surveys divided by the time interval. Associations between SES and EACs of blood pressure were evaluated using generalised estimating equations.
Results: Lower SES was significantly associated with greater annual increases of blood pressure among Chinese older adults. The effect of SES on EACs of blood pressure was more pronounced among non-hypertensive participants. Compared to EACs among non-hypertensive participants with high SES, multivariable-adjusted EACs among those with low SES increased by 0.57 mmHg (95% confidence interval [CI]: 0.16, 0.99), 0.32 mmHg (95% CI: 0.07, 0.57), and 0.40 mmHg (95% CI: 0.13, 0.66) for systolic blood pressure, diastolic blood pressure, and mean arterial pressure, respectively.
Conclusions: This study revealed strong associations between SES and EACs of blood pressure among Chinese older adults, especially in the non-hypertensive population. Findings suggest that prevention strategies for hypertension should pay more attention to the older population with low SES.
