Relationship of Body Mass Index and Waist Circumference to Blood Pressure and Hypertension Prevalence in Employees in Shougang Shuicheng Iron and Steel Corporation

Objective To explore the relationship of body mass index(BMI) and waist circumference to blood pressure and hypertension prevalence in employees in Shougang Shuicheng iron and steel corporation.Methods Two thousand four hundred and ninety-six employees in Shougang Shuicheng iron and steel corporation were surveyed using a multi-stage random cluster sampling method.Medical examination included blood pressure measurement(SBP and DBP),height,BMI and waist circumference.Results The BMI was(23.18±3.34) kg·m-2and waist circumference was(80.37±10.02) cm.Among the 2 496 employees,the overweight and obesity accounted for 38.22%(954/2 496) and abdominal obesity accounted for 36.26%(905/2 496).The hypertension prevalence in male participants(BMI:18,≥18-24,≥24-28,≥28 kg·m-2or waist circumference:75,≥75-85,≥85 cm) were significantly higher than that in female participants(all P0.05).The hypertension prevalence in male participants(BMI 24 kg·m-2,waist circumference 85 cm;BMI 24 kg·m-2,waist circumference ≥85 cm;BMI 24-27.9 kg·m-2,waist circumference85 cm;BMI 24-27.9 kg·m-2,waist circumference ≥85 cm;BMI ≥28 kg·m-2,waist circumference ≥85 cm) were obviously higher than that in female participants(BMI24 kg·m-2,waist circumference80 cm;BMI24 kg·m-2,waist circumference ≥80 cm;BMI 24-27.9 kg·m-2,waist circumference80 cm;BMI 24-27.9 kg·m-2,waist circumference≥80 cm;BMI≥28 kg·m-2,waist circumference≥80 cm)(P0.05 or P0.01).Conclusion The hypertension prevalence in male employees is significantly higher than that in female employees in Shougang Shuicheng iron and steel corporation.The control of BMI and waist circumference is beneficial to the prevention of hypertension.
