Could mom’s pre-pregnancy bp predict baby gender aud to usd forecast 2016


THURSDAY, Jan. 12, 2017 (HealthDay News) — The gender of a woman’s future child may be linked to her blood pressure six months before she becomes pregnant, a preliminary study suggests.

A team of Canadian and Chinese researchers found that a higher pre-pregnancy blood pressure reading may be associated with a greater likelihood for delivering a baby boy binary domain. Conversely, lower blood pressure may favor the odds of giving birth to a girl.

But the researchers only found an association between pre-pregnancy blood pressure and a baby’s gender exchange rate usd rmb. They did not prove a cause-and-effect connection.

How might a mom-to-be’s blood pressure predict her baby’s gender? That’s not completely clear us futures markets. The researchers suspect blood pressure may be related to the gender of those babies carried to term, not lost to miscarriage.

"When a woman becomes pregnant, the sex of a fetus is determined by whether the father’s sperm provides an X or Y chromosome, and there is no evidence that this probability varies in humans," said study lead author Dr funny quotes. Ravi Retnakaran.

"But what is believed to vary is the proportion of male or female fetuses lost during pregnancy," he said, referring to the risk for miscarriage or other pregnancy loss.

In other words, the findings suggest either that lower maternal blood pressure shortly before pregnancy boosts the likelihood of carrying a female fetus to term, or higher blood pressure before pregnancy boosts the likelihood for carrying a male fetus to term, Retnakaran said.

But, he added, "This is an association — not cause and effect — between a woman’s blood pressure before pregnancy and her likelihood of delivering a boy or girl when she becomes pregnant."

Retnakaran said researchers have previously observed that large "societal events" — such as natural disasters or an economic depression — appear linked to shifts in the boy-girl birth ratio.

"We hypothesized that there are likely to be physiologic factors in a woman that relate to her likelihood of carrying a boy or a girl when she becomes pregnant," he said.

The new study included just over 1,400 newly married women in Liuyang, China, and began in 2009 binary search tree visualization. All the women indicated an intention to become pregnant within six months.

All of them underwent full lab tests to record their blood pressure, cholesterol, triglyceride and glucose levels british pound us dollar exchange rate. These measurements were taken at an average of six months before pregnancy.

Once the women became pregnant, their health was tracked euro today exchange rate. All received routine obstetric care, including continual monitoring of blood pressure shifts, as well as the diagnosis of any complications throughout their pregnancies.

The study authors found that women who gave birth to boys had registered a higher pre-pregnancy systolic blood pressure (the upper number in a blood pressure reading) than women who gave birth to girls gender identity issues. Mothers of boys averaged about 113 mm Hg, versus mothers of girls who had an average near 110 mm Hg.

The researchers adjusted the data for maternal age, educational background, smoking history, obesity, and cholesterol, triglyceride and blood sugar levels uk to us currency. They found the blood pressure gap held.

But, he said more and larger studies are needed to further explore the association convert cny to usd. And, he added, no one should view the study findings as an instruction manual for gender selection.

"The only evidence-based medicine data that we have that can allow gender selection is doing in-vitro fertilization with pre-implantation genetic screening," Singer said. "This method has been around for more than 20 years, has been performed among hundreds of thousands of women, and has been proven to be more than 99 percent accurate in determining future gender. And it is safe."
