Though using marijuana for medical or recreational reasons is legal in a growing number of U.S. states, it may come with some unexpected side effects.

A new study found that women who use cannabis may be reducing their fertility.

"Cannabis use has continued to climb. More and more states have legalized it in recent years," said Sunni Mumford, an inves...

The COVID-19 pandemic is taking a toll on the emotional health of pregnant women whose exercise routines have been disrupted because of the coronavirus, new research shows.

Those women had higher depression scores than their counterparts who were able to exercise as usual, the researchers found.

"Our results demonstrate that the COVID-19 pandemic may exacerbate the elevated risk th...

THURSDAY, Dec. 31, 2020 -- Even the most privileged people in the United States with the best access to health care are sicker and more likely to die than average folks in other developed nations, a new study finds.

People living in the highest-income counties in the United States are, on average, more likely to die from a heart attack or cancer, during childbirth, or to lose an infant th...

Exposure to metals may disrupt pregnant women's hormones and boost the odds of complications such as preeclampsia, preterm birth and low birth weight, according to a new study.

Metals such as nickel, arsenic, cobalt and lead have been associated with pregnancy complications, but it's been unclear why.

"A delicate hormonal balance orchestrates pregnancy from conception to delivery an...

A large new study suggests that men who plan to be fathers should try to get themselves in shape first.

Researchers found that when fathers-to-be had health conditions like high blood pressure or obesity, the odds that their partner might experience miscarriage or stillbirth increased.

The findings do not prove that a father's health directly affects his partner's pregnancy, experts...

A new study may prove reassuring for expectant moms: Pregnant women who are infected with COVID-19 during their third trimester appear unlikely to pass the infection to their fetuses.

This study was conducted between April and June 2020 among women who came to one of three Boston area hospitals either for treatment of COVID-19 or for delivery.

None of the newborns of the 127 pregnan...

Most pregnant women infected with the new coronavirus don't have symptoms, a new study shows.

Researchers analyzed data from a coronavirus screening program in the labor and delivery unit of Elmhurst Hospital in New York City during March and April.

Of the 130 pregnant women screened, one-third tested positive for the new coronavirus.

Of the women who tested positive, 72% d...

Although heart problems are rare complications of pregnancy, Black women face a heightened risk -- even if they have comfortable incomes and health insurance, a new study finds.

It's well established that the United States has a higher maternal mortality rate than other wealthy nations, and Black women are at greater risk than white women.

Less has been known about whether Black wom...

When a young woman is diagnosed with breast cancer, many questions go through her mind.

What treatments does she need? Will she survive? And will she still be able to have a baby?

In a review of recent research, an international team of investigators say the answer to that critical third question is yes. Though breast cancer survivors are less likely to become pregnant than the ave...

COVID-19 may be behind a concerning rise in the number of women suffering anxiety and depression before and soon after childbirth, a new study says.

Researchers from Brigham and Women's Hospital in Boston surveyed more than 1,100 pregnant and postpartum women between May 21 and Aug. 17. They found that 36%, or more than 1 in 3, had significant levels of depression. Prior to the pandemic,...

In the past 30 years, U.S. women have been in progressively worse physical shape as they become pregnant, a new study finds.

A combination of obesity, high blood pressure, diabetes and having children later in life have led to potentially more complications, and even infant and maternal death, researchers say.

Obesity is a major driver of these complications, said lead researcher Dr...

Freezing their eggs or ovarian tissue before breast cancer treatment increases survivors' chances of having children after recovery, a new study finds.

Nearly 10% of breast cancer cases occur in women younger than 45 years of age, some of whom haven't yet had children, according to researchers at the Karolinska Institute in Sweden.

Treatment often includes chemotherapy, which can da...

The number of women who contemplate suicide or self-harm during or after pregnancy may be on the rise, a large, new study suggests.

Among nearly 600,000 U.S. childbearing women, researchers found that close to 2,700 were diagnosed with suicidality in the year before or after giving birth. And the diagnosis -- defined as suicidal thoughts or intentional self-harm -- grew more common over t...

Pregnant women with COVID-19 have little risk of developing severe symptoms, as do their newborns, a new study finds.

In fact, 95% of these women have good outcomes, and just 3% of their babies test positive for COVID-19, researchers say.

"For 5% of COVID-19-positive pregnant women, however -- those who get very sick -- the risks to both mother and baby are significant," said study ...

American women are far more likely to die from pregnancy-related causes than women in other wealthy countries -- and a national shortage of maternity care providers bodes ill for the future.

Those are some of the findings from a new report on maternal mortality by the nonprofit Commonwealth Fund, which compared the United States with 10 other high-income nations.

It found what the r...

Scientists are reporting early success with an experimental herpes vaccine that uses a genetically modified version of the virus.

The gene edit prevents the virus from performing its normal evasive maneuver: hiding out in nervous system cells in order to elude the immune system.

So far, the vaccine has only been tested in lab animals. But scientists hope the genetic tweak will ...

WEDNESDAY, Nov. 11, 2020 (HealthDay) -- The number of women entering pregnancy with high blood pressure has nearly doubled in a decade, new research finds.

The study found that 2% of women living in urban areas and 2.4% of women living in rural areas had high blood pressure as they started their pregnancies in 2018. When the researchers looked back at 2007, those numbers were 1.1% and 1.4...

Global warming could increase rates of serious pregnancy problems, researchers warn.

They analyzed 70 studies from 27 countries that reported associations between high temperatures and preterm birth, birth weight and stillbirths.

"Given increases in the frequency and intensity of heat waves, the number of pregnant women exposed to these conditions worldwide, and the significant...

Many women have depression symptoms after giving birth, but for some postpartum depression hangs on for years, a U.S. government study finds.

Of nearly 4,900 new mothers researchers followed, one-quarter had depression symptoms at some point in their child's first three years. And for about half of them, the symptoms either started early on and never improved, or took time to emerge.

Pregnancy can increase the risk of a rare, dangerous heart condition called aortic dissection, researchers report.

This is especially true for women with underlying heart conditions that can go undetected.

Aortic dissections -- which affect 3 in 100,000 people per year -- cause the layers of the aorta to tear, and blood to pool or leak instead of flow normally. Patients requ...

Hispanic mothers-to-be in the southern United States are almost twice as likely to have COVID-19 as non-Hispanic women, a new study finds.

The researchers also found that those with government health insurance were more likely to test positive for the coronavirus than women with private insurance.

For the study, pregnant women were routinely tested for COVID-19 as they wen...

Low levels of thyroid hormone during pregnancy may contribute to the development of attention deficit hyperactivity disorder in the child, new research suggests.

The study found that children born to mothers with low thyroid hormone levels during the first trimester of pregnancy had a 28% increased risk of being diagnosed with ADHD later.

Thyroid hormones play an impor...

Women who suffer severe morning sickness may have higher risk of depression during and after pregnancy, according to a new British study.

It enrolled 214 women in London during the first trimester of pregnancy. Half had severe morning sickness; half did not. None had been treated for mental health conditions during the previous year.

The women's mental health was assessed in...

If you're pregnant and you think popping nonsteroidal anti-inflammatory drugs (NSAIDs) for your aches and pains is safe, think again.

The U.S. Food and Drug Administration warned on Thursday that taking these widely used painkillers -- which include Advil, Motrin, Aleve and Celebrex -- at 20 weeks or later in a pregnancy could raise the risk of complications.

Specifically, t...

In some reassuring news on the coronavirus front, a new study finds that pregnant women with COVID-19 rarely infect their newborn.

That finding suggests that it may not be necessary to separate infected mothers from their infants and that moms can continue to breastfeed, the researchers added.

"Our findings should reassure expectant mothers with COVID-19 that basic infectio...

Children whose mothers were given an epidural during labor may face a slightly heightened risk of autism, a large, new study suggests.

Researchers found that the rate of autism was a little higher among those kids, versus their peers whose mothers did not get epidural pain relief during childbirth: 1.9% versus 1.3%.

The reasons for the difference are not yet known. A...

COVID-19 symptoms can last a long time in pregnant women, researchers say.

The new study included 594 pregnant women (average age 31) across the United States who tested positive for the new coronavirus but were not hospitalized. Nearly one-third were health care workers.

On average, the women were about 24 weeks' pregnant when they joined the study.

The most comm...

Metals and other air pollutants have been found in the placentas of new mothers, which means such pollutants may be able to reach the fetus, researchers report.

"Our study for the first time shows that inhaled carbon particulate matter in air pollution travels in the blood stream, and is taken up by important cells in the placenta. We hope that this information will encourage policy m...

The foundation for early heart disease might begin not during childhood or in the years that follow, but in the womb.

Researchers studying nearly 30 years of data from families in Manitoba, Canada, found a strong connection between heart disease risk factors in teens and young adults and their mother's type 2 or gestational diabetes.

"I was surprised at the strength of the a...

Babies born to mothers with COVID-19 only rarely suffer from effects of the virus, a new study suggests.

These newborns generally do well in the six to eight weeks after birth, but more are admitted to the neonatal intensive care unit (NICU) if their mothers had COVID-19 in the two weeks before delivery.

Of more than 200 babies studied, complications including preterm birt...

There may be a slightly increased risk of autism for each week a child is born before or after 40 weeks of gestation, according to a new study.

Researchers are still trying to pinpoint the causes of autism, but both genetic and environmental factors are believed to play a role.

Some previous studies have suggested that being born before or after full term (40 weeks) may be a...

Expectant mothers who smoke pot in pregnancy could increase their baby's risk for mental or emotional problems later in childhood, a new study finds.

Marijuana use during pregnancy was associated with a host of problems in the preteen years, researchers report.

Children exposed to pot in the womb were more likely to experience internalizing disorders such as depression and a...

COVID-19 may hit pregnant women especially hard, U.S. health officials warned in two reports.

In one report, scientists from the U.S. Centers for Disease Control and Prevention urge pregnant women and health care providers to be aware of the risks for severe COVID-19, which include serious birth outcomes.

Diagnosing COVID-19 during childbirth hospitalizations is important ...

Mom's breast milk can be altered by antibiotics in ways that might harm an infant's health, according to a new study.

The Canadian researchers were particularly concerned with an increase in bacteria that can be harmful, namely a bacterium called Pseudomonas that can cause a serious intestinal infection called necrotizing enterocolitis in a preterm infant.

About 7%...

The narcolepsy medicine modafinil doesn't appear to increase the risk of birth defects, according to a new study that contradicts earlier research.

"This study is based on twice as many pregnancies as earlier studies, and we find no increase in the risk of malformation in infants exposed to modafinil during pregnancy," lead author Carolyn Cesta, of the Karolinska Institute in Sweden, ...

A new review may offer guidance on women who contract COVID-19 during pregnancy.

Pregnant women with COVID-19 are less likely to have symptoms than those who aren't expecting -- but they're more likely to require critical care, according to the study.

Having COVID-19 also increases a mother-to-be's risk of having a preterm baby and of her baby being admitted to the neonatal ...

Pregnant women are understandably worried about everything that goes into their bodies. But here's one worry they can cross off that list: flu shots.

A large, new study has confirmed that an expectant woman's flu shot doesn't increase the risk of autism in her child. And that's true even if the vaccine is given during the first trimester of pregnancy, the Swedish study found.

...

New insight into how pregnant women can pass the Zika virus to their fetus could point to ways to prevent it, researchers say.

Babies infected with Zika in the womb can have abnormally small heads (microcephaly) and other birth defects.

In this study, researchers examined placenta samples collected from pregnant women during the peak of Brazil's 2015 to 2016 Zika outbreak. S...

A new case study adds to growing evidence that the new coronavirus can be transmitted from a pregnant woman to her fetus.

"It's very important to bring to the forefront this finding that mothers and infants can be affected by COVID-19, transmission can occur during pregnancy, and pregnant mothers need to protect themselves," said Dr. Amanda Evans, senior author of the report.

<...

Women who are pregnant or trying to get pregnant may need to forgo coffee, tea, sodas and other sources of caffeine. A new data analysis finds no safe level of the drug during this time.

"The cumulative scientific evidence supports pregnant women and women contemplating pregnancy being advised to avoid caffeine," concluded study author Jack James, a professor at Reykjavik University...

Here's some reassuring news for pregnant women: In-person doctor visits don't appear to make them vulnerable to COVID-19, a new study indicates.

It included thousands of Massachusetts women who had babies at four Boston-area hospitals between April 19 and June 27, 2020.

In the spring of 2020, there was a surge in COVID-19 cases in the Boston area, so the hospitals tested all...

As many expectant mothers can unhappily attest, the nausea and vomiting known as "morning sickness" can occur at any time of the day.

In a new study, British researchers analyzed diaries kept by 256 women from the day they learned they were expecting until the 60th day of their pregnancy.

While vomiting was most common between 7 a.m. and 1 p.m., nausea was likely all day lon...

For pregnant women experiencing painful gallstones, immediate surgery to remove the infected gallbladder may be better than postponing the operation until after childbirth, a new study suggests.

Acute gallbladder disease is called cholecystitis.

"Current guidelines recommend surgery for acute cholecystitis during pregnancy, but many patients and providers delay surgery," sa...

Obesity during pregnancy may hinder fetal brain development, a new study suggests.

Development of brain areas involved in decision-making and behavior may be affected as early as the second trimester, New York University researchers said.

For the study, the researchers examined nearly 200 groups of active nerve cells in the fetal brain.

"Our findings affirm that...

Research has shown that pot use during pregnancy may increase the risk of stillborn birth, preterm birth and low birth weight.

Now, a new study adds another danger: children whose mothers used pot while pregnant could be at greater risk for autism.

And the increased danger wasn't slight: Using data on every birth in Ontario, Canada, between April 2007 and March 2012, the Uni...

Some key molecules used by the new coronavirus to cause infection aren't found in the placenta, which may explain why the virus is rarely detected in fetuses or newborns of women with COVID-19.

U.S. government researchers found that placental membranes lack the messenger RNA (mRNA) molecule required to make the ACE2 receptor. SARS-CoV-2 -- the virus that causes COVID-19 -- uses that c...

Kids whose moms used pot while pregnant may end up with sleep problems years later, a new study suggests.

Looking at thousands of 9- and 10-year-olds, University of Colorado researchers found that children were more likely to have trouble falling asleep or staying asleep if their mother had used marijuana prenatally.

"While not explicitly causal, the results are consistent...

It's a virus some might not even remember, but babies born to mothers infected with Zika who appeared normal at birth still experienced neurological or developmental problems, new research suggests.

A hallmark of infection with the mosquito-borne Zika virus in pregnant women is delivering a baby with an abnormally small head -- a condition called microcephaly. But as children exposed ...

Poverty and crowded living conditions increase the spread of the coronavirus that causes COVID-19, a new study suggests.

Researchers reached that conclusion after testing nearly 400 women who gave birth at two hospitals in New York City during the peak of the COVID-19 outbreak.

"Our study shows that neighborhood socioeconomic status and household crowding are strongly assoc...

Here's more bad news associated with climate change: Pregnant women exposed to air pollution or heat waves face a greater risk of having a preterm or underweight baby, a new research review finds.

The review, of 68 studies from across the United States, found that the large majority arrived at the same conclusion: Babies were at greater risk when their mothers lived in areas with poor...
