In pregnant women, having more Veillonella bacteria in the mouth was linked to lower blood pressure readings.

Scientific Claim

The abundance of Veillonella in the oral microbiota was negatively correlated with maternal systolic and diastolic blood pressure at 36 weeks gestation in pregnant women.

Original Statement

“Maternal systolic and diastolic blood pressure at 36 weeks gestation were negatively correlated with the abundance of the nitrate-reducing Veillonella genus whereas maternal blood pressure was positively correlated with the abundance of Mycoplasma and Methanobrevibacter (Table 2).”

Can only show association/correlation

Assessment Explanation

The claim correctly states 'negatively correlated' which accurately describes the statistical relationship found in the observational study. No causal language is used.

Similar Assertions

In pregnant women, higher levels of Veillonella bacteria in the mouth were linked to higher levels of Prevotella bacteria.

81%

Pregnant women who later got preeclampsia had less of a specific bacteria called Veillonella parvula in their mouths compared to women who stayed healthy during pregnancy.

79%

In pregnant women, the amount of Veillonella dispar bacteria in the mouth wasn't linked to systolic blood pressure, but showed a similar pattern to diastolic blood pressure that wasn't quite statistically significant.

73%

In pregnant women, higher levels of Veillonella parvula bacteria in the mouth were linked to lower diastolic blood pressure, and showed a similar but less strong pattern for systolic blood pressure.
