Measured of hypertension was defined as hypertensive if their systolic blood pressure (SBP) ≥ 140 mmHg and/or diastolic blood pressure (DBP) ≥ 90 mmHg22 (link)23 . The key advantage in using data collected in CHARLS is that blood pressure is measured in the survey. Details on how blood pressure measurements are taken in the survey can be found elsewhere20 . Briefly, in CHARLS, each respondent’s systolic and diastolic blood pressures were recorded three times by a trained and qualified nurse using an HEM-7112 electronic monitor (Omron, Kyoto, Japan) in the respondent’s home. We used a binary variable for measured hypertension according to the mean value of the three readings.
Hem 7112 electronic monitor
Manufactured by Omron
Sourced in Japan
The HEM-7112 is an electronic blood pressure monitor designed to measure and display the user's blood pressure and heart rate. It features an automatic inflation system and large digital display for easy readability. The monitor is intended for personal use in a home setting.

This is a cross-sectional study based on data from the China Health and Retirement Longitudinal Study (CHARLS) 2015. This study is designed to explore the association of community-based BP monitoring utilisation with hypertension control. CHARLS respondents were followed using a computer-aided personal interview every 2 years. A structured questionnaire with several main sections was used to collect data from each subject. One section was used to record height, weight and blood pressure. Each subject’s systolic and diastolic blood pressures were recorded three times by a trained nurse using a HEM-7112 electronic monitor (Omron, Kyoto, Japan). The mean values for each subject were then calculated. The interviewees were asked face-to-face if they were taking any form of anti-hypertensive medication and how often they had blood pressure examination by village or community doctors in the last year.

Although clinical guidelines recommend screening at least twice, 1 to 4 weeks apart, hypertension was defined based on blood pressure measurements at 1 time point in this study.
24 (link) Blood pressure was measured 3 times by investigators using validated instruments, including the Omron HEM‐780 Intellisense Automated Blood Pressure monitor with ComFit cuff in the United States, the Omron HEM‐907 in England, the HEM‐7112 electronic monitor in China, and the Omron Blood Pressure monitor in India. For each participant, the mean of 3 available measures was used as estimates of systolic blood pressure and diastolic blood pressure. Participants were considered as having hypertension if they had 1 of the following indicators: systolic blood pressure ≥140 mm Hg, diastolic blood pressure ≥90 mm Hg, or a history of high blood pressure (ie, if a health care provider had ever told participants they had high blood pressure or hypertension) (TableS3 ).

26 (link) Medication status was asked only to those participants who self‐reported high blood pressure or hypertension. Spousal concordance of hypertension was defined as both partners in a couple having hypertension.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
