Key result
Higher white blood cell count was associated with increased odds of hypertension, with an adjusted OR of 1.19 (95% CI 1.08-1.31) for the highest versus lowest quintile (p for trend < 0.001).
Why the study?
Is higher white blood cell count associated with an increased risk of hypertension in Chinese adults?
Cross-Sectional (n=39,282)
Is higher white blood cell count associated with an increased risk of hypertension in Chinese adults?
Odds Ratio: 1.19 (95% CI 1.08–1.31)
p-value: p=< 0.001
Higher white blood cell count is independently associated with an increased prevalence of hypertension in Chinese adults, with an additive effect observed with BMI.
Increased blood pressure was associated with increased white blood cell count (adjusted p < 0.001) in a community-based health examination survey of adults in China (n = 39 282; aged 18-93 years). Adjusted odds ratios (95% confidence intervals) for hypertension across white blood cell count quintiles were 1.00, 0.99 (0.89-1.09), 1.11 (1.01-1.22), 1.09 (0.99-1.20), and 1.19 (1.08-1.31) (p for trend < 0.001). Body mass index and white blood cell count had an additive effect on systolic blood pressure (p for interaction = 0.047). Therefore, white blood cell count could independently predict hypertension in Chinese adults.

Sun et al. (2015) conducted a cross-sectional in Hypertension (n=39,282). White blood cell count vs. Lowest quintile of white blood cell count was evaluated on Hypertension (OR 1.19, 95% CI 1.08-1.31, p=< 0.001). Higher white blood cell count was associated with increased odds of hypertension, with an adjusted OR of 1.19 (95% CI 1.08-1.31) for the highest versus lowest quintile (p for trend < 0.001).
