Potential Link Between Body Weight, Diet And Non-Hodgkin Lymphoma

Another possible disease of choice.
Body weight in young adulthood and diet appeared to be associated with the risk for non-Hodgkin lymphoma, according to results presented at the 10th AACR International Conference on Frontiers in Cancer Prevention Research, being held Oct. 22-25, 2011.

"The causes of non-Hodgkin lymphoma (NHL) are poorly understood, and unfortunately, we don't know very much about specific ways to prevent or lower the risk for this disease," said Kimberly Bertrand, Sc.D., research fellow in the department of epidemiology at the Harvard School of Public Health.

In previous analyses of the Nurses' Health Study at 14 years of follow-up, lead researcher Shumin Zhang, M.D., Sc.D., and colleagues reported positive associations with NHL for trans fat intake and inverse associations for vegetable intake. To expand those findings, Bertrand and colleagues evaluated the association of obesity, specific types of dietary fats and fruits and vegetables with risk for NHL.

Researchers analyzed questionnaire responses from 47,541 men followed for 22 years in the Health Professionals' Follow-Up Study and 91,227 women followed for 28 years in the Nurses' Health Study. Among the women, researchers confirmed 966 incident diagnoses of NHL through 2008, and among the men, they confirmed 566 cases through 2006.

"In analyses that controlled for age, race and other factors, we found that obesity in young adulthood (ages 18 to 21 years) was associated with risk for NHL later in life," Bertrand said. "Men who were obese (body mass index [BMI] equal to or greater than 30) [in young adulthood] had a 64 percent higher risk for NHL compared with men who were lean, while obese women had a 19 percent higher risk."
Why risk it?

Lose the weight.
