BACKGROUND: A study was conducted to estimate the impact of hypertension screening on blood pressure measured 1, 2, and 3 years after baseline, as well as how its impact varies across socioeconomic statuses.
METHODS: Embedded within a subcohort of the ChinaHEART (China Health Evaluation and Risk Reduction Through Nationwide Teamwork) project, blood pressure was measured both at baseline and follow-up visits. Information about socioeconomic factors, including education, annual household income, occupational status, and urbanity, was also collected. A sharp regression discontinuity design was used to estimate the impact of hypertension screening on blood pressure measured 1, 2, and 3 years later. We also explored the role of baseline socioeconomic status by adding the interaction term.
RESULTS: The regression discontinuity analysis found no effect of baseline hypertension screening on the primary outcomes. When stratified by socioeconomic status, regarding systolic blood pressure measured 1 year later, the impact of screening was 5.52 mm Hg (95% CI, -1.55 to 12.59) for individuals with primary or lower education, 0.80 mm Hg (95% CI, -4.00 to 5.59) for middle education, and -7.39 mm Hg (95% CI, -12.03 to -2.75) for high school or above education, with a significant trend observed (P for interaction=0.002). In addition, among individuals with high school or above education, the impact on systolic blood pressure 1, 2, and 3 years later was -7.39 mm Hg (95% CI, -12.03 to -2.75), -8.30 mm Hg (95% CI, -15.79 to -0.81), and -4.63 mm Hg (95% CI, -12.71 to 3.44), respectively. These patterns, although insignificant, were also found for other socioeconomic factors. The impact on diastolic blood pressure was smaller and insignificant.
CONCLUSIONS: The impact of community-based hypertension screening on systolic blood pressure was affected by individual's education level and lasted only in the short term.
