RESUMO
Objective To investigate the prevalence of hyperuricemia in health check-up population of Beijing suburb.Methods Total 1 336 rural residents in Nankou Township of Beijing received health check-up from July to Aug 2014,including 686 subjects aged 20-59 years (young/middle-aged group) and 650 subjects aged 60-96 years (elderly group).The blood pressure and body mass index (BMI) were measured;serum uric acid (SUA),fasting blood glucose (FBG) and blood lipids (TG,TC,HDL-C,LDL-C) were determined.The SUA levels ＞ 420 μmol/L for male and ＞ 360 μmol/L for female were defined as hyperuricemia.Results The four quartiles of SUA levels were 27.00-254.59 μmol/L (Q1),254.60-302.35 μmol/L (Q2),302.36-359.78 μmol/L(Q3) and 359.79-702.0 μmol/L (Q4).The prevalence of hyperuricemia was significantly higher in young/middle-aged group than that in elderly group [20.41％ (140/686) vs.13.85％ (90/650),x2 =10.08,P =0.001 5],the systolic blood pressure [SBP,(126.8±15.7) vs.(116.7±12.0)mmHg(1 mmHg=0.133 kPa),t=2.76,P=0.008],FBG [(7.40±4.10) vs.(6.11 ±2.03)mmol/L,t=2.12,P=0.036],TC [(5.52±1.10) vs.(5.23±1.00)mmol/L,t =2.04,P =0.045],LDL-C [(3.5 ±0.7) vs.(2.4 ±0.9)mmol/L,t =2.21,P =0.029]in young/middle-aged group were significantly higher than those in elderly group.BMI,FBG were significantly higher in Q4 than those in other quartiles [BMI:(26.44 ± 3.88) vs.(24.19 ± 3.37),(25.49±3.42) and (25.61 ±3.49)kg/m2,t =2.78,P=0.008;FBG:(8.19 ±1.52) vs.(6.34±1.34),(6.09 ± 1.51) and (6.40 ± 1.98) mmol/L,t =2.80,P =0.007].The triglyceride (TG) levels in group Q3 and Q4 [(1.85 ± 0.90) and (1.92 ± 0.44) mmol/L] were higher than those in Q1 and Q2 [(1.37 ±0.76) and (1.70 ±0.84) mmol/L,t =2.1,P =0.035].Only 9.57％ subjects (22/230)with hyperuricemia was not combined with metabolic disorder;subjects combined with one and two metabolic disorders accounted for 20.87％ (48/230) and 69.57％ (160/230),respectively.Conclusion Screening for hyperuricemia is important for comprehensiye treatment and management of hyperuricemia in rural residents,especially in the young and middle-aged population.
