BPA Consumed During Pregnancy Linked to Obesity in Kids

1:45

Bisphenol A (BPA) is a chemical produced in large quantities and used primarily in polycarbonate plastics and epoxy resins.

You’ll find polycarbonate plastics in some plastic water bottles, food storage containers and plastic tableware. Epoxy resins are used in lacquers to coat metal products such as food cans, bottle tops, and water supply pipes.

The primary source of exposure to BPA for many people is through food and beverages.

Why should you be concerned about Bisphenol A?

BPA is thought to act as an endocrine disruptor--a compound that mimics or disrupts hormones produced by the human body. Previous research has linked BPA to asthma, ADHD, depression, anxiety and early puberty in girls. It has also been linked to diabetes, obesity and heart disease in adults.

A new study has also found a possible link between BPA and child obesity.

Researchers at Columbia University found that children of women exposed to BPA during pregnancy were likely to have more body fat by age seven. Increased body fat has been linked to a higher risk of obesity.

"This study provides evidence that prenatal exposure to BPA may contribute to developmental origins of obesity as determined by measures of body fat in children as opposed to the traditional indicator of body mass index, which only considers height and weight,” lead author of the study. Lori Hoepner, DrPH, said in a press release.

Dr. Hoepner and her colleagues studied 369 maternal-child pairs from pregnancy through early childhood.

The researchers collected urine samples during the last three months of pregnancy.

Urine samples were also collected from the children at ages three and five. The children's heights and weights were measured at age five and age seven.

At age seven the researchers also measured waist circumference and fat mass.

The researchers found 94 percent of the women had BPA in their urine--an indication that they had been exposed to the chemical.

Dr. Hoepner and colleagues found that children who had been exposed to BPA in the womb had a higher body fat mass. Even though the children might have been within the normal ranges for height and weight, they had a greater percentage of fat than would be normal at that age.

The researchers found a strong association between BPA, fat mass and waist circumference in girls. They also found that childhood exposure to BPA was not associated with fat mass, indicating that the prenatal exposure was the problem.

Some studies indicate that infants and children may be the most vulnerable to the effects of BPA. This new study also suggests that pregnant women might want to avoid BPA products.

The National Institute of Environmental Health Sciences offers these tips for reducing BPA exposure:

•       Don’t microwave polycarbonate plastic food containers. Polycarbonate is strong and durable, but over time it may break down from over use at high temperatures. Use glass or ceramics for microwaving foods.

•       Plastic containers have recycle codes on the bottom. Some, but not all, plastics that are marked with recycle codes 3 or 7 may be made with BPA.

•       Reduce your use of canned foods. Choose glass or other safe packaging or fresh or frozen foods when possible.

•       Opt for glass, porcelain or stainless steel containers, particularly for hot food or liquids.

•       Use baby bottles that are BPA free. 

The study was published in the May issue of Environmental Health Perspectives.

Toddlers at High Risk for Chemical Eye Burns

1:45

You might think that most chemical eye burns occur at work places, but according to a new study, more toddlers than adults are treated at emergency rooms.

"Household cleaners are a huge culprit," said Dr. R. Sterling Haring, who led the study. Spray bottles frequently have been implicated in other research, he said.

"The rates among 1-year-olds are 1.5 times higher than the highest rate of [eye] injury for working-age adults," said Haring, a doctoral candidate at Johns Hopkins Bloomberg School of Public Health in Baltimore.

Researchers analyzed data from 900 hospitals and found more than 144,000 ER visits related to chemical eye burns across all age groups.

When the researchers broke the data down by year of life, 24-year-olds had the highest rate among adults. Among children, 1- and 2-year-olds were injured most often, with this age group 1.5 times more likely to get an eye burn than a 24-year-old, the findings showed.

"We see chemical eye injuries in the little kids all the time," said Dr. Roberto Warman, a pediatric ophthalmologist at Nicklaus Children's Hospital in Miami, who wasn't involved in the study.

"It's always the same story. They got access to the cleaners in the house. These are some extremely serious injuries," Warman said.

The investigators discovered that when the chemical agent that caused the burn was known, alkaline injuries were more common than acid injuries. Alkaline agents are found in oven cleaners, drain cleaners, chlorine bleach and ammonia products, according to background notes in the study.

Alkaline chemicals can continue to burn into the eye even after contact with the compound, Haring explained. Damage can be blinding, he said.

Workplaces often have precautions set up to avoid eye accidents while home products are not always locked or secured in a place a child can’t reach. Warman and Haring agreed that parents and industry could do a better job protecting young children.

The toddlers' injuries occur at home most often and are more common among lower-income families. They also are more common in the South, according to the analysis of 2010-2013 data from the Nationwide Emergency Department Sample.

Haring's advice: Never keep household chemicals under the sink. "It's a terrible idea, even with a lock," he said.

Instead, store all cleaning supplies and other potentially harmful products "in a lockable cabinet out of reach," he said. Supervise their use if, for instance, older children are using them. Also, be sure to turn the spray bottle nozzles to the "off" position before storing them, Haring advised.

In addition, Warman said, "The industry can also help us more. They can make caps in a way that they are harder and harder to open."

Even with precautions, however, chemicals might sometimes get into the eye. If that happens, run tap water over the eye for a while, Haring said. Emergency room doctors usually rinse the child's eye with saline for 20 minutes or more, often after applying antiseptic eye drops to reduce the pain, according to information from Boston Children's Hospital.

The study was published online Aug. 4 in JAMA Ophthalmology.
