Washington, July 2 (ANI): A new study has found that lesbians are nearly twice as likely to be overweight than heterosexual women.

Researchers at Vanderbilt University School of Nursing are now using an extraordinarily successful, predominately lesbian weight loss group in Atlanta, as a model system for discovering how to target obesity in a lesbian population.

Sarah Fogel, Ph.D., R.N., associate professor of Nursing at Vanderbilt University School of Nursing, is studying the group, and her findings are giving her a different view on weight loss.

All weight loss groups offer an environment of like-bodied people (overweight or obese), but this is the first group, to my knowledge, that has been developed around other personal and social issues, said Fogel.

Adherence to a new lifestyle is often the most difficult barrier to overcome in weight loss.

However, the Atlanta group has had remarkable success in developing long-term change in its members lifestyles.

Perhaps the best representation of the group is to say that there are still several women in the group who were founding members. They have been attending since October 2006 and continue to come even though a couple of them have reached their weight loss goals, Fogel said.

The other side of this is that even the women who have not been able to lose what they want to lose keep coming . . . this is unheard of. It says volumes about the group, she added.

Being overweight or obese can result in a number of health problems, namely cardiovascular disease and diabetes.

Heart disease is the leading cause of death worldwide, so understanding how obesity develops in different populations is a pressing concern.

Fogel will study the group over a six-month period, both empirically and qualitatively.

Using body mass index (BMI) and relative weight loss, she will put a number on the groups success.

Fogel has already held focus groups in order to lend a deeper, more personal aspect to the study, and therefore weight loss. (ANI)
