Abstract:
Objective To identify the use of body mass index (BMI) to predict the areas under curve (AUC) of hypertension,and to find the optimal cutoff of predicting the incidences of hypertension in Chinese adults. Method Using the data from Nationwide Nutrition and Health Survey to find the new cases of four-years hypertension,and to calculate the four-year cumulative incidence (CI) of hypertension,and operate the receiver operating characteristic (ROC),analyze the AUC and calculate the sensitivity and specificity of optimal cutoff. Results Four-year CI of hypertension were 17.2% (20.3% for men and 14.2% for women),the AUC were 0.62 and 0.61 for men and women,respectively. Conclusion The optimal cut off was applicable in monitoring the incidences of hypertension,and more verification should be carried out in the future when applying this cut off.
