Adolescent's weight, socioeconomic status may affect cancer later in life

14.10.2013
May affect risk of developing esophageal and gastric cancer

Overweight adolescents were twice as likely as their normal weight peers to later develop esophageal cancer in a recent study from Israel.

The study, which is published early online in CANCER, a peer-reviewed journal of the American Cancer Society, also found that lower socioeconomic status as well as immigration from higher risk countries were important determinants of gastric cancer.

Zohar Levi, MD, MHA, of the Rabin Medical Center in Israel, and his colleagues measured body mass index in one million Israeli adolescent males who underwent a general health examination at an average age of 17 years from 1967 to 2005, and through the country's cancer registry, identified which of the participants later developed cancer. Participants were followed from 2.5 to almost 40 years, with an average follow-up of 18.8 years.

The researchers were amazed to find that events -- particularly weight and socioeconomic status -- up to the age of 17 years had a tremendous impact upon cancer development later in life. Adolescents who were overweight had a 2.1-fold increased risk of developing esophageal cancer. Adolescents who were of low socioeconomic status had a 2.2-fold increased risk of developing intestinal type gastric cancer.

Those who had nine years or less of education had a 1.9-fold increased risk of developing this type of cancer. Also, immigrants born in Asian and former USSR countries had higher risks of developing gastric cancer (3.0-fold and 2.28-fold increased risks, respectively).

"Adolescents who are overweight and obese are prone to esophageal cancer, probably due to reflux that they have throughout their life. Also, a lower socioeconomic position as a child has a lot of impact upon incidence of gastric cancer as an adult," said Dr. Levi.

"We look at obesity as dangerous from cardiovascular aspects at ages 40 and over, but here we can see that it has effects much earlier." He noted that it is unclear whether losing weight later in life or gaining higher socioeconomic status might reduce the risks observed in this study.

Im Focus: Penn engineers develop ultrathin, ultralight 'nanocardboard'

When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure

Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
