Key result
Higher hematocrit is independently linked to increased diastolic blood pressure in young men.
Why the study?
High hematocrit level has been reported as a correlate of hypertension in aged people but has not been examined in younger generations.
Does hematocrit level correlate with blood pressure in healthy young male office workers?
Cross-Sectional (n=646)
No
Does hematocrit level correlate with blood pressure in healthy young male office workers?
Effect estimate: Standardized partial regression coefficient 0.203
p-value: p=<0.001
Increased hematocrit is independently associated with higher diastolic blood pressure in young male office workers, suggesting its utility in assessing cardiovascular risk.
May inform diastolic BP risk assessment in young male workers; hypothesis-generating and requires prospective validation before practice change.
High hematocrit (Ht) level has been reported to be a correlating factor of hypertension in aged people, but has not been examined in younger generation. To investigate the association between Ht and blood pressure (BP) in healthy young workers, statistical analysis was performed for 646 male employees, using cross-sectional health-check data. Ht was positively correlated with systolic blood pressure (SBP) and with diastolic blood pressure (DBP) by Pearson's simple correlation analysis. Multiple regression analysis for SBP and DBP was conducted by stepwise procedure, using Ht, age, body mass index (BMI), and drinking and smoking habits as independent variables. It was revealed that Ht was a significant independent variable for DBP (p < 0.001), as well as age and BMI, but not for SBP. These findings suggest that increased Ht is an important variable for assessing risk for cardiovascular disorders, especially diastolic hypertension, in young male office workers.

Nishikido et al. (1999) conducted a cross-sectional in Healthy young male office workers (n=646). Hematocrit was evaluated on Diastolic blood pressure (Standardized partial regression coefficient 0.203, p=<0.001). Higher hematocrit levels were significantly and independently associated with increased diastolic blood pressure (p<0.001) in healthy young male office workers.
