Можно быть конечно несогласным, но joint national comittee опирается на данные исследований, которые были проведены за последние годы... И на основании этих исследований выдает новые рекоммендации:
"Since the “Sixth Report of the Joint National Committee on the Prevention,
Detection, Evaluation, and Treatment of High Blood Pressure (JNC 6)” was
released in 1997, new knowledge has come to light from a variety of sources.
The National High Blood Pressure Education Program Coordinating
Committee (NHBPEP CC), which represents 46 professional, voluntary, and
Federal organizations, has periodically reviewed the emerging findings during its
biannual meetings.
Eventually, a critical mass of information accumulated that
generated much demand for a seventh report. My decision to appoint a JNC 7
Committee was predicated on four reasons:
(1) publication of many new hypertension observational studies and clinical trials; (2) need for a new, clear, and concise guideline that would be useful for clinicians; (3) need to simplify the
classification of blood pressure; and (4) clear recognition that the JNC reports
were not being used to their maximum benefit"
