But UCLA researchers say they don't have enough evidence to prove it

Researchers from the University of California, Los Angeles (UCLA), claim that they've found a correlation between prenatal cell phone exposure and behavioral issues during childhood, but do not have enough data to say that it's a sure thing. 

Leeka Kheifets, Ph.D., study leader and a professor of epidemiology at UCLA's School of Public Health, along with her team of researchers, have found a possible relationship between a mother's cell phone use while pregnant and behavioral problems in the child later on. 

There are quite a few theories that suggest cell phones may have other negative effects on the human body, but according to Scientific American, it really depends on who you ask. While some theories have noted that it may contribute to brain tumors and cancer, others say the opposite.

"There are theories, but we do not know," said Kheifets. "Exposure to the fetus is likely to be very low, so it's unclear how it can influence fetal development."

To find this possible correlation, Kheifets and her team of researchers analyzed the data on mothers who participated in the Danish National Birth Cohort study, which asked them lifestyle questions including amount of cell phone use during and after pregnancy. They also studied data on cell phone use from these mothers' children, which amounted to 28,745 7-year-olds. 

The mother's were interviewed when their children turned seven, where they were asked about the child's cell phone use and behavioral problems. According to the study's overall results, 18 percent of children were exposed to cell phone use before and after pregnancy. Now, 35.2 percent of 7-year-olds used a cell phone, but less than one percent of them used a cell phone for more than one hour a week. Based on what their mother's said, 93 percent of the children had no behavioral issues while 3.1 percent showed signs of hyperactivity/inattention, relationship problems and conduct problems. 

The next step, according to Kheifets, is to conduct this study again when the children are 11 years old. Kheifets would like to see if these percentages remain stable over the years, or if they take a drastic turn one way or the other. 

Despite the fact that researchers are unsure as to whether cell phone use negatively influences a child's behavior, Kheifets warns that it can't hurt to reduce exposure anyway.

"Be aware of your exposure and while the science develops, use precaution," said Kheifets. "It is very easy to reduce exposure by keeping your phone away from the body and using a hands-free device, so why not do it?"

I call BS on this study...

For several reasons. First, the study states:

They simply correlate the percentage of ADHD in children with them being exposed to cellular radiation. That is all. This does not imply causation! They don't even have enough data to prove it.

Furthermore, simple logic and science can go large bounds to disprove this theory.

Firstly, radio waves do not penetrate salt water well at all! The womb of a mother is full of amniotic fluid, which, coincidentally, is comprised of practically the same salinity as seawater (0.9% I believe). It has been proven that only very low frequency radio waves can penetrate salt water. Regular water is a different story, but the presence of salt in the solution makes a huge difference. This is the precise reason why nuclear submarines can only use VLF radio transmissions underwater (up to 30 khz) and that is only up to a depth of 20 meters. If they need to use UHF or VHF, they have to surface.

Secondly, this study was based on findings over a seven year period; GSM has been around since the 1990's and was being introduced here in the states in the late 90's and early 2000's. At the very least, these phones were operating at 380 MHz or higher. UHF is defined as 300 MHz to 3 GHz; VHF is from 30 MHz to 300 MHz.

Wait, both of those are a fair bit higher than 30 KHz.

Hold on a minute. I've been around for some time, I'm in my mid-30's and I've suffered from ADHD my whole life. It's a real condition as far as I'm concerned but I'm doing just fine with it. Wait, there weren't cell phones in the 70's so how come I have it? Now, with this logic, I'm basing my conclusion on theirs--correlation equals causation. But, it doesn't. :) It never does. We need facts, we need data. As far as I'm concerned, I've provided a little inkling here to start to chip away at their theory. I deserve some government money to waste.
