"The study participants were selected from a dataset contained in the NOSE study, a prospective cohort study conducted continuously since 2020. The purpose of the NOSE study is to determine the effect of HBPM and recording on preventing the development of CVD, frailty, and cognitive decline. Participants in the NOSE study were recruited between August 2020 and August 2021 from community-dwelling adults aged at least 40 years in Nose Town, a regional town with approximately 10 000 inhabitants located in Osaka Prefecture, Japan. The participants were divided into intervention and nonintervention groups based on their residence in 44 districts. Each district was allocated to either the intervention or nonintervention group to ensure that sex distribution, aging rates, health check participation rates, and turnout was nearly equal between both groups. The NOSE study was registered in the UMIN-clinical trial Registry (No. UMIN000039349). Participants were recruited through the town's newsletter, health checkup sites, community activity sites, and mass COVID-19 vaccination sites. Baseline enrollment was 1153 participants, representing 15.9% of the Nose Town residents aged at least 40 years. At baseline, each participant attended 1 of 79 venue surveys conducted during the recruitment period. Venue surveys were conducted at the Health and Welfare Center and community centers located in 38 of the 44 districts in Nose Town. Some community centers were excluded because of limited space. Participants in the intervention group were provided a self-monitoring HBPM device (HEM-7281T, OMRON HEALTHCARE Co. Ltd., Kyoto, Japan) and a BP-recording notebook at the baseline survey. They were encouraged to measure their HBPs twice in the morning and twice in the evening from the day of the baseline survey, according to the HBPM instructions in the guidelines of the Japanese Society of Hypertension [], and to record their HBPs in a notebook. BP notebooks were collected approximately every 6 months after each participant's baseline survey. On the basis of these records, the hypertension specialist on the study team provided feedback to the participants."
