Babies in womb treated for obesity

Ultrasound of fetus in womb

Ultrasound of fetus in womb - Babies in womb treated for obesity, As a fetus grows, it's constantly getting messages from its mother. It's not just hearing her heartbeat and whatever music she might play to her belly; it also gets chemical signals through the placenta. A new study, which will be published in Psychological Science, a journal of the Association for Psychological Science, finds that this includes signals about the mother's mental state. If the mother is depressed, that affects how the baby develops after it's born.

In recent decades, researchers have found that the environment a fetus is growing up in -- the mother's womb -- is very important. Some effects are obvious. Smoking and drinking, for example, can be devastating. But others are subtler; studies have found that people who were born during the Dutch famine of 1944, most of whom had starving mothers, were likely to have health problems like obesity and diabetes later.

Curt A. Sandman, Elysia P. Davis, and Laura M. Glynn of the University of California-Irvine study how the mother's psychological state affects a developing fetus. For this study, they recruited pregnant women and checked them for depression before and after they gave birth. They also gave their babies tests after they were born to see how well they were developing.

They found something interesting: what mattered to the babies was if the environment was consistent before and after birth. That is, the babies who did best were those who either had mothers who were healthy both before and after birth, and those whose mothers were depressed before birth and stayed depressed afterward. What slowed the babies' development was changing conditions -- a mother who went from depressed before birth to healthy after or healthy before birth to depressed after. "We must admit, the strength of this finding surprised us," Sandman says.

Now, the cynical interpretation of our results would be that if a mother is depressed before birth, you should leave her that way for the well-being of the infant. "A more reasonable approach would be, to treat women who present with prenatal depression. Sandman says. "We know how to deal with depression." The problem is, women are rarely screened for depression before birth.

In the long term, having a depressed mother could lead to neurological problems and psychiatric disorders, Sandman says. In another study, his team found that older children whose mothers were anxious during pregnancy, which often is co morbid with depression, have differences in certain brain structures. It will take studies lasting decades to figure out exactly what having a depressed mother means to a child's long-term health.

"We believe that the human fetus is an active participant in its own development and is collecting information for life after birth," Sandman says. "It's preparing for life based on messages the mom is providing."

The study is entitled, "Prescient human fetuses thrive."

Despite protests and pressure from feminists and pro-abortion groups, an 11-year-old girl in the Mexican city of Chetumal has refused to undergo an abortion. The young girl explained her decision saying that she understands, "a life is growing in her womb."

The girl is receiving medical attention at a local clinic, where doctors say the results of psychological tests have been positive. The recent tests, said Lizbeth Gamboa Song, director of the National System for the Comprehensive Development of the Family, show the girl has a proper understanding of the new life within her and of what to expect during the pregnancy.

Dr. Juan Carlos Navarrete Jaimes of the Merida Clinic performed an ultrasound on the girl and found the mother and child to be in excellent health. He also provided guidance on the prenatal care she needs during the coming months to ensure the pregnancy proceeds without complications.

Gamboa said that while the girl understands she is carrying a new life within her, "She does not yet fully realize the consequences of what it will mean to raise and care for a child" because of her young age.

She understands what happens before a pregnancy, she knows her womb will grow, she knows at some point her water will break, and she knows how the baby will be born," Gamboa said.Efforts to curb childhood obesity are starting earlier than ever in the United Kingdom, where doctors are trying to slim down babies before they're even born (read about the 'rise of the sumo baby.'). A trial study, which involves administering a drug (which drug?) to overweight pregnant women and monitoring their developing fetuses (find out which states have the most obese children) could be widely replicated if successful.
