Abstract
Prevalence of interarm systolic blood pressure difference and clinical and demographic characteristics associated with interarm systolic blood pressure difference (IASBPD) have been a matter of debate. We aimed to ascertain the prevalence of IASBPD and clinical and demographic characteristics associated with it. We searched PubMed, EMBASE, and CINAHL, Ovid and Cochrane Library, and Google Scholar. Twenty-seven studies meeting all inclusion criteria were included in the analysis. Weighted average cumulative prevalence of simultaneous IASBPD of 10, 15, and 20 mmHg or greater was 9.49% [95% confidence interval (CI) 7.9-11.1%], 5.3% (95% CI 3.1-7.5%), and 4.4% (95% CI 1.5-7.4%), respectively. The prevalence of IASBPD of 10 mmHg was 9% (95% CI 7-11%), 7.5% (95% CI 5.6-9.4%), and 12.1% (95% CI 8.2-16.1%) in outpatient, community, and hospital-based setting, respectively. The prevalence of IASBPD of 15 mmHg was 4.9% (95% CI 2.7-7.2%) in outpatient and 8% in hospital setting. The prevalence of IASBPD of 20 mmHg was 4.4% (95% CI 2.8-11.6%) in outpatient and 4.4% (95% CI 2.1-6.8%) for the hospital setting. Pairwise meta-analysis of five studies showed that the presence or absence of IASBP was not associated with age, sex, diabetes, hyper...Continue Reading
