Abstract：Objective To evaluate vitamin D status in middle-aged population between urban and rural areas in Shan-dong.Methods A total of 1 792 middle-aged residents between the ages of 40 to 75 were selected in this cross-sectional research after age and sex matching .All residents were asked to complete a physical examination and blood pressure meas-urement.The serum 25-hydroxyvitamin D levels were determined by enzyme-linked immunosorbent assay .The serum 25 ( OH) D levels between urban and rural residents were compared by independent T test .Partial correlation and bivariate lo-gistic regression analysis were used to explore the correlation between serum 25(OH)D levels and blood pressure .Results The mean average of serum 25(OH)D levels were 48.83 nmol/L and about 60.05%of the subjects were vitamin D defi-ciency.The serum 25 ( OH) D levels were lower among urban residents than among rural residents .After adjustment for age, sex, area and drinking status, no significant correlations were found between 25(OH)D and systolic blood pressure (SBP) or diastolic blood pressure (DBP) (P>0.05).The result of bivariate logistic regression analysis showed that ser-um 25(OH)D levels were not associated with hypertension (OR=-0.003,95%CI:0.991~1.004,P=0.425).Conclu-sion Vitamin D deficiency was very common in middle-aged population and urban residents had lower serum 25 ( OH) D levels than rural residents.Blood pressure was not correlated with serum 25(OH)D levels in middle-aged population.
