Hem907 blood pressure monitor

This was gathered in all participants at the time of imaging, and also at follow-up in the prognostic group. Clinical data was obtained using questionnaires. Angina, heart attack and stroke were self-reported. Physical activity in the previous week was self-reported using the International Physical Activity Questionnaire [18 (link)]. Minutes/week spent on work-related, domestic and leisure-time physical activity at moderate and vigorous intensity was recorded together with time spent in active transport (classified as moderate intensity). Participants’ diets were recorded using a 127-item food frequency questionnaire [19 (link)]. Data on education and smoking were obtained through self-report at baseline and follow-up by using a questionnaire [15 (link)]. Education was classified into four categories: university or higher university degree, diploma certificate or equivalent, year 12 or equivalent and less than year 12.
Height and weight were measured at both time-points without headwear and heavy clothing. Body mass index was calculated as weight(kg)/[height(m)]². Blood pressure was measured while sitting after at least a 5-min rest using an Omron HEM907 Blood Pressure Monitor (Omron Corporation, Kyoto, Japan) at baseline and follow-up. Biochemical parameters were measured in fasting blood samples by standard laboratory procedures [15 (link)].

Nurses collected anthropometric data (weight, height), blood pressure (BP) and non-fasting blood samples using standard protocols. Body weight was measured without shoes and in light clothing using Tanita electronic scales, and height was measured using a stadiometer with the Frankfort plane in the horizontal position. BMI was calculated as weight (kilograms)/height (meters) squared. Systolic and diastolic BP was measured with an Omron HEM-907 blood pressure monitor three times in the sitting position after 5-min rest between each reading. The initial reading was discarded, and an average of the second and third BP recordings was used for the present analyses. Blood samples were analyzed for high-sensitivity C-reactive protein (CRP), high-density lipoprotein (HDL) cholesterol, triglycerides and glycated hemoglobin (HbA1c). Detailed information on the technicalities of the blood analysis, the internal quality control and the external quality assessment for the laboratory have been described elsewhere (11 ). Additional data were collected on physician diagnosed conditions (hypertension, diabetes) and medication use.
