Relationship between hemoglobin level and blood pressure in policemen in Guangzhou city

Objective To explore the relationship between hemoglobin(Hb)level and blood pressure in the policemen of Guangzhou city, Guangdong province for the prevention of hypertension.Methods Totally 2 120 policemen in Haizhu district of Guangzhou city were selected and divided into four groups based on their Hb levels.Systolic blood pressure(SBP), diastolic blood pressure(DBP), and pulse pressure(PP)of the participants were measured;the relationship between Hb level and the prevalence of hypertension was analyzed.Results Among the participants, SBP was positively correlated to Hb level(r=0.211, P<0.01), whereas DBP was positively correlated to Hb level(r=0.271, P<0.01);the prevalence of hypertension was positively correlated to Hb level(r=0.099, P<0.01).Conclusion The increase of Hb may be an independent risk factor of hypertension.
