EMBARGOED FOR RELEASE: 11 A.M. (ET), TUESDAY, NOVEMBER 24, 2020
Media advisory: To contact the U.S. Preventive Services Task Force, email the Media Coordinator at Newsroom@USPSTF.net or call 202-572-2044. The full report and related articles are linked to this news release.
Bottom Line: The U.S. Preventive Services Task Force (USPSTF) recommends offering or referring adults with cardiovascular disease risk factors to behavioral counseling interventions to promote a healthy diet and physical activity. Adults who adhere to national guidelines for a healthy diet and physical activity have a lower risk of cardiovascular disease and death than those who do not. The USPSTF routinely makes recommendations about the effectiveness of preventive care services. This statement is mostly consistent with its 2014 recommendation, although it no longer includes adults with impaired glucose tolerance or type 2 diabetes because this population is now included in a separate USPSTF recommendation.

Media advisory: To contact the U.S. Preventive Services Task Force, email the Media Coordinator at Newsroom@USPSTF.net or call 202-572-2044. The full report and related articles are linked to this news release.
Bottom Line: The U.S. Preventive Services Task Force (USPSTF) concludes that the current evidence is insufficient to make a recommendation about screening for high blood pressure in children and adolescents. High blood pressure (both primary and secondary) occurs in 3 to 4 percent of children and adolescents in the United States. The USPSTF routinely makes recommendations about the effectiveness of preventive care services and this statement, which applies to children and teens ages 3 to 18 not known to have hypertension or who are without symptoms, is consistent with its 2013 statement.
