High Blood Pressure Linked With Certain Oral Bacteria in Older Women:

High blood pressure is typically defined by two measurements: systolic blood pressure (the upper number measuring pressure when the heart beats) of 130 mm Hg or higher, and diastolic blood pressure (the lower number indicating pressure between heart beats) of 80 mm Hg or higher.

While previous research has indicated that blood pressure tends to be higher in people with existing periodontal disease compared to those without it, researchers believe that this study is the first to prospectively examine the association between oral bacteria and developing hypertension.

"Since periodontal disease and hypertension are especially prevalent in older adults, if a relationship between the oral bacteria and hypertension risk could be established, there may be an opportunity to enhance hypertension prevention through increased, targeted oral care," said Michael J. LaMonte, Ph.D., M.P.H., one of the study's senior authors, a research professor in epidemiology at the University at Buffalo - State University of New York and a co-investigator in the Women's Health Initiative clinical center in the University's epidemiology and environmental health department.

Researchers evaluated data for 1,215 postmenopausal women (average age of 63 years old at study enrollment, between 1997 and 2001) in the Buffalo Osteoporosis and Periodontal Disease Study in Buffalo, New York. At study enrollment, researchers recorded blood pressure and collected oral plaque from below the gum line, "which is where some bacteria keep the gum and tooth structures healthy, and others cause gum and periodontal disease," LaMonte said. They also noted medication use and medical and lifestyle histories to assess if there is a link between oral bacteria and hypertension in older women.
