The study of 1,011 adolescents (aged 10-15) and their mothers from low income families living in three cities — Boston, Chicago and San Antonio — was posted on the Web site of the Journal of Adolescent Health (http://www.jahonline.org/inpress), which will publish it in the August issue. Forty-seven percent of the teens in the sample were overweight or obese, but that percentage increased to 56.2 percent among those who were impacted by four or more stressors.

 ”We found that an adolescent or youth who’s more stressed — caused by such things as having poor grades, mental health problems, more aggressive behavior, or doing more drugs and alcohol — is also more likely to be overweight or obese,” said lead author Brenda Lohman, an Iowa State assistant professor of human development and family studies (HDFS).

 Susan Stewart, an ISU associate professor of sociology; and Steven Garasky, a professor of HDFS at Iowa State; joined Lohman on the research team. Former ISU faculty members Craig Gundersen, a member of the agricultural and consumer economics faculty at the University of Illinois; and Joey Eisenmann, a member of the kinesiology and pediatrics faculty at Michigan State University; also contributed to the study.

The study analyzes data obtained from the “Welfare, Children and Families: A Three-City Study” — a six-year longitudinal investigation. Researchers measured the height and weight of the adolescents to determine their body mass index, which was subsequently used to determine weight status based on two widely used classification systems. Adolescent food insecurity status and individual, maternal and family stressors were also determined through interviews.

The five factors used to determine the individual stressor index for the adolescents were:

* Academic problems

* Consumption of drugs and alcohol

* Depression or poor mental health levels

* Acting out or aggressive behaviors

* Lack of future orientation [...]

The study also found that a mother’s stress, [...]contributes to a child’s chances of becoming overweight or obese. [...]

While this study singles out mothers, fathers aren’t immune to their child’s weight status either.

“My own research focuses on fathers and shows that fathers, too, have an effect on children’s eating habits and obesity,” said Stewart, author of the book “Brave New Stepfamilies,” who had another study posted by the Journal of Adolescent Health last month on nonresident father involvement and adolescent eating patterns.

“In our latest study, we found that kids who are involved with nonresident dads eat better — more vegetables, less fast food,” she said. “However, similar to the Lohman study, living with a single mom was associated with worse eating habits.”

Lohman says the new research should emphasize the need for healthcare professionals to take a more holistic approach in their treatment of obese teens.

“We absolutely have to focus on their (teens) health, well-being, nutrition and exercise — and education of these things for them,” she said. “But we really need to also look holistically at their life and work towards reducing stress [...]
