Is Gender Tied to Mother's BP Before Conception?

A large study recently published in the American Journal of Hypertension showed a connection between mothers' blood pressure and their babies' gender. The study, which was conducted in China and began recruiting in 2009, included 1,411 women of childbearing age.

For the study, researchers measured blood pressure, blood glucose levels, cholesterol, and triglycerides about 26 weeks before the women conceived. Subsequent pregnancies resulted in 739 male births and 672 female births.

When the researchers adjusted for other factors, such as age, smoking, cholesterol levels, etc., they found that systolic blood pressure before conception was higher in women who gave birth to boy babies. More research is needed, but maternal blood pressure might be a previously unrecognized factor associated with gender.
