BACKGROUND/AIMS: Ambulatory blood pressure (BP) monitoring has been widely recommended for evaluating the status of BP, but is lacking in practicality. Determination of the specific time points for BP measurement that are representative of 24-hour mean BP could be useful and convenient in @entity101 @entity1 with @entity740 ( @entity740 ). METHODS: A total of 1,317 @entity1 for whom 24-hour ambulatory BP monitoring was performed were enrolled in a multicenter study on @entity101 @entity740 . We analyzed the time points at which systolic blood pressure ( @entity5351 ) values exhibited the smallest differences from 24-hour mean @entity5351 ( @entity5351 ). We included office @entity5351 and analyzed the relationships between SBPs at the office and the time points with the smallest differences from 24-hour @entity5351 using several methods. RESULTS: The time points with the smallest differences from 24-hour @entity5351 were 7:00 AM, 2:00 PM, and 9:30 PM. In regression analysis, SBPs at 7:00 AM and 9:30 PM were better correlated with 24-hour @entity5351 than SBPs at 2:00 PM and the office. The proportions of @entity1 with SBPs within 30% of 24-hour @entity5351 were higher at 7:00 AM and 9:30 PM. The best consistency between the uncontrolled @entity101 groups, defined as >=  135 mmHg of 24-hour @entity5351 and higher values of SBPs corresponding to 135 mmHg of 24-hour @entity5351 , were observed at the 7:00 AM and 9:30 PM time points. CONCLUSIONS: The specific time points for SBPs that correlated well with 24-hour @entity5351 in @entity101 @entity740 @entity1 were 7:00 AM and 9:30 PM.
