    Objectives

    The role of lead exposure a risk factor for hypertension is less well defined among women than among men.

    This case-control study assessed the relation of blood and bone lead concentrations to hypertension in women.

    Methods

    Cases and controls were a subsample of women from the Nurses'Health Study.

    Hypertension was defined as a physician diagnosis of hypertension between 1988 and 1994 or measure systolic blood pressure >=140 mm Hg or diastolic blood pressure >= 90 mm Hg.

    Results

    Mean (SD) blood lead concentration was 0.15 (0.11) mumol/L ; mean tibia and patella lead concentratikons by K-x-ray fluorescence were 13.3 (9.0) and 17.3 (11.1) mug/g, respectively.

    After adjustment for potentially confounding factors, an increase from the 10th and the 90th percentile of patella lead values (25 mug/g) was associated with approximately 2-fold (95% confidence interval=1.1,3.2=increased risk of hypertension.

    There was no association between hypertension and either blood or tibia lead concentrations.

    Conclusions

    These findings support a potentially important role for low-level lead exposure as a risk factor for hypertension among non-occupationally exposed women.
