Background: The current analysis was performed to estimate the percentage and number of Chinese adults with hypertension and the percentage and number of Chinese adults recommended to receive pharmacological antihypertensive treatment according to the 2017 American College of Cardiology/American Heart Association (ACC/AHA) guideline compared with the same parameters according to the 2010 Chinese guideline.
Methods: We used 2011 data from the China Health and Nutrition Survey (CHNS). A total of 12,499 Chinese adults aged ≥18 years with complete blood pressure (BP) values were selected for the present analysis.
Results: The crude prevalence rates (95% CI) of hypertension according to the definitions from the 2017 ACC/AHA guideline and the 2010 Chinese guideline were 58.0% (57.2 to 58.9%) and 25.4% (24.7 to 26.2%), respectively. Moreover, the percentage of the participants recommended to take antihypertensive medications were 31.5 and 28.8%, respectively. Among adults who took antihypertensive medications, 88.8% had above-goal BP levels compared to 53.3%. Overall, 613.3 million Chinese adults (aged ≥18 years) met the criteria for hypertension according to the 2017 ACC/AHA guideline, and 267.7 million met the criteria according to 2010 Chinese guideline. An additional 28.4 million (2.7%) Chinese adults were recommended to take antihypertensive medication.
Conclusions: The present analysis revealed that the 2017 ACC/AHA hypertension guideline will result in a substantial increase in the percentage and number of Chinese adults defined as having hypertension and a small increase in the percentage of adults who are recommended to take antihypertensive medications compared to the same parameters based on the 2010 Chinese guideline. More intensive management and antihypertensive medications use are suggested to improve the control rate of hypertension among Chinese adults.
