The Mom Vivant / The orignial “laborers” – Moms!

As Isaac bears down, a news report on MyHealthNewsDaily by editor Karen Rowan asks the question of whether hurricanes can bring on labor? Talk about a great answer to the question, of “What’d you do for Labor Day?

Exactly what triggers the start of labor remains a mystery, but folklore holds that the weather may influence a baby’s arrival. With Hurricane Isaac making landfall, and two other storms brewing in the eastern Atlantic, some may be wondering if the Southeast is due for an increase in births.

Several studies have suggested that drops in barometric pressure can trigger either the onset of labor, or the rupture of the fluid-filled amniotic sac membrane, which is the technical term for a woman’s water breaking or starting to leak.

“There’s definitely a belief out there,” said Dr. Jonathan Schaffir, associate professor of obstetrics and gynecology at Ohio State University College of Medicine. “It’s certainly not cut-and-dried, but there is some scientific evidence that changes in pressure can contribute to membrane rupture,” he said.

Of the studies that have looked at whether the weather might trigger pregnant women’s water to break, two have suggested that it can, while two others have found no association, Schaffir said.



How could the weather trigger labor?

“The idea behind this belief is that the amniotic sac is like a balloon, and if you lower the external pressure on it, there is an increased risk it can ‘pop,'” Schaffir said.

However, in his own experience as a practicing obstetrician for 18 years, Schaffir said he has seen no link between weather events and women going into labor. “In reality, the amniotic sac is protected. It’s kind of hard to imagine that a small drop in barometric pressure would cause a change in the amniotic sac,” he said.

Dr. Salih Yasin, a practicing obstetrician for 25 years in Miami, also said he has not seen any increase in women going into labor during hurricanes.

As for the studies that have suggested a link, their usefulness in practice is doubtful, said Yasin, who is an associate professor of obstetrics and gynecology at the University of Miami Miller School of Medicine. The ranges of the barometric pressure changes in the studies were not very large, he noted.

In one study, researchers considered 162 women who, over the course of a year, went into labor at a Houston hospital around times of significant air pressure drops. Using air pressure data from the National Oceanic and Atmospheric Administration (NOAA), the researchers found that more women started labor after a drop in barometric pressure than prior to a drop, according to the study, published in 1997 in the Journal of Nurse-Midwifery. For example, for one drop in pressure, three women went into labor prior to it, but 11 began labor after it.

When looking at the 12 pressure drops that occurred that year, they found 66 women began labor prior to pressure drops, whereas 96 women began labor after the drops.

However, another study’s results cast doubt on the link. In that 1996 study of about 2,400 pregnant women published in the American Journal of Obstetrics and Gynecology, the researchers found no link between days with the lowest pressure and the number of women who began labor.

But when the pressure drops were broken down into three-hour time periods, there was a link: fewer women went into labor during the hour after a period of falling air pressure.

“We were surprised to find a significant decrease in the onset of labor,” after the pressure drops, the researchers wrote.

Hurricane Andrew and labor

Yasin and a colleague looked at deliveries around Aug. 24, 1992, when the lowest barometric pressures drops during Hurricane Andrew were noted, at the University of Miami Jackson Memorial Hospital, which had the most deliveries in Miami-Dade County before, during and after Hurricane Andrew hit, Yasin said.

The researchers looked births and complications of pregnancy, and related them to NOAA data on barometric pressures, taking into account women’s ZIP codes, to determine where they lived in relation to the Andrew’s path. No association between air pressure and labor onset was found, Yasin said.

The most important things pregnant women can do during extreme weather events are to maintain their safety, eat and stay hydrated, he said.

Pass it on: Weather conditions such as hurricanes are unlikely to make pregnant women go into labor.

It's all about jobs

It’s all about jobs

Jobs, jobs, jobs … really job creation is all Americans want to hear from their politicians.  According to the latest polls,  Americans are the most pessimistic they’ve ever been.  Jon Huntsman published an opinion piece in the Wall Street Journal blaming Obama for adding “zero jobs to the economy” in August.  A pro-environment, pro-gay moderate Republican, Huntsman may not be registering in the polls but his jobs program is eliciting cheers from Wall Street.  He wants to close ALL loopholes for the wealthy, lower the corporate tax rate and roll back Obamacare.  Where he might hit a roadblock is over his plan to eliminate the deduction on the interest you pay on your mortgage, one of the most popular – and the only in some cases – tax break for middle class families.  Romney hinted about his plan in a speech to Hispanic voters Friday, saying he is going to open up energy exploration here in the U.S., cap spending at 20% of the Gross Domestic Product and slash taxes at the same time.  In a speech on Labor Day, Obama talked about putting a million out of work construction workers back to work rebuilding our country’s bridges and schools and creating an infrastructure bank to pay for it that would draw on private funds.  His decision to abandon tougher restrictions on smog emissions last week was greeted on the left as heresy and on the right, as a small step that could free businesses up to focus on creating jobs instead of complying with new regulations.

Labor Day Jobs Talk

How to get Americans back to work or how to get our economy working again will be the focus of plans by both Republicans and Democrats that will be rolled out after this holiday weekend.  The Republicans are touting a “don’t tread on me” approach to regulations across the board, arguing that rolling back environmental, healthcare and labor relations edicts will free businesses up to … well, to do more business.  They’re also hoping to insulate small business owners by calling for a 20% tax deduction for them.  Republican strategists are warning candidates that addressing the debt ceiling didn’t really do it for voters.  Independent voters want action now to reverse a 9% unemployment rate that has been there for 25 of the past 27 months.  Obama is expected to unveil an infrastructure program to build new schools that would draw from moneys pooled from federal, state and local resources.  He wants to extend the payroll tax that dropped the payroll tax from 6-4%.  We’ll know more details when he releases his program next week.
