Body weight and height were measured to determine the body mass index (BMI) of each participant. Systolic (SBP) and diastolic blood pressure (DBP) were measured using an electronic BP monitor (Omron HEM-8712, Omron Co.Ltd, Kyoto, Japan). In addition to the above-mentioned clinical parameters, two bio makers associated with inflammation and cardiometabolic health were measured, namely CRP and APN.

Blood pressure was measured using an upper-arm digital automated sphygmomanometer (HEM-8712) from Omron in both intervention and control groups. Two blood pressure measurements were taken at rest in a sitting position for each patient. The interval between the first and second measurements was ≥2 minutes, and the average of the 2 measured values was used for this study. During the remote examination, the patient reported the blood pressure measurements taken on the day of the examination through video, and the doctor confirmed the blood pressure values visually.

All interviewers and investigators were trained on the study procedure before the commencement of the study. Interviews via standardised questionnaires were used to gather participants’ demographic information and personal clinical history (presence of comorbidities, smoking status, LLT use and family history (premature coronary artery disease [PCAD])). Physical examination findings, including anthropometric measurements such as weight, height, body mass index (BMI), waist circumference (WC) and hip circumference (HC), were recorded on-site. Blood pressure was measured twice, two minutes apart, in a sitting position using automatic digital blood pressure (BP) monitors (Omron HEM-8712, Japan). The average of the last two systolic and diastolic measurements was used as the BP reading for the individual participants.

Blood pressure was our primary independent variable. Prior to measuring, arm circumference was measured to use appropriate size cuff. Systolic and diastolic blood pressures were measured thrice using a standard digital sphygmomanometer (Portable Omron BP monitor, model HEM-8712) on the same arm, with interval of at least five minutes between each BP measurement. Participants were asked to sit and relax for at five minutes before taking the first reading.[10 ] First, second, and third systolic and diastolic readings were recorded at equated time intervals. The mean of all three readings was taken as the final reading for our study.
High blood pressure was defined by JNC-7 criteria (Systolic blood pressure ≥140 mmHg and diastolic blood pressure ≥90 mmHg). However, those with systolic blood pressure more than 270 mmHg or less than 70 mmHg, and diastolic blood pressure more than 140 mmHg or less than 40 mmHg were omitted from analysis. Individuals having blood pressure more than 140/90 mmHg on two or more occasions or on medication for hypertension were considered as self-reported hypertensives. Hypertension status was further sub-grouped as controlled and uncontrolled on the basis of the mean systolic and diastolic blood pressure at the time of survey.

The systolic and diastolic blood pressure was measured 3 times for each participant using a portable blood pressure monitor (HEM-8712, Omron Healthcare Inc).19 (link) We discarded the first reading and considered the mean of the last 2 readings to avoid upward bias from anxiety or nervousness while taking the first reading.20 (link) Hypertension was defined as having a mean systolic blood pressure of 140 mm Hg or higher or mean diastolic blood pressure of 90 mm Hg or higher21 (link) or responding yes to the following question: “Are you currently taking medications prescribed to lower blood pressure?” This question was asked of all participants regardless of their blood pressure measurements.

As previously described, certified study nurses will be trained to measure BP according to a standardized protocol approved by the World Health Organization [45 ]. We used this protocol in our previous randomized trial of storytelling in Vietnam. This protocol was written for use with the OmROn HEM-8712 automated BP monitor, with special attention to assessment and maintenance of the instrument’s accuracy and training/certification of research assistants. Using a proper cuff size, measurements are taken after sitting quietly for 5 min, with the arm supported on a flat surface, with the upper arm at heart level. Three measurements are separated by at least 1 min, and values from the last two measurements will be averaged. Height and weight will be measured in the absence of shoes and heavy clothing while waist and hip sizes will be measured by placing the tape horizontally around the smallest part of the waist and the widest portion of the hips, respectively.

Blood pressure will be measured by an automatic digital sphygmomanometer (HEM-8712, Omron, Kyoto, Japan). Students will be asked to sit down on a chair and rest their right elbow on a table. Blood pressure will be measured three times allowing at least 5 min interval between each measurement. The mean of second and third measurement will be taken into analysis. Presence of systolic blood pressure ≥ 130 mm of Hg and/or diastolic blood pressure ≥ 80 mm of Hg will be considered as having high blood pressure.

We used data from a nationally representative household research survey [National Family Health Survey (NFHS)-4] conducted during 2015–16 in 640 districts of India [17 ]. The NFHS-4 used two-stage cluster random sampling stratified by urban and rural to select households. Primary sampling units -villages (rural) or census enumeration blocks (urban) were selected by population proportion to size. NFHS-4 included women in the age group of 15–49 years and men in the age group of 15–54 years. The BP was measured three times (after five minutes rest and a five-minute gap between the three measures) of the left arm (right arm if left arm is injured) in a sitting position using an automated BP measurement device (Omron HEM 8712) [18 ].

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.
