Study of sisters reinforces importance of healthy living

National Institutes of Health press release

Sister Study

These are among the first findings coming out of the NIH’s Sister Study, which is just completing its enrollment of 50,000 women aged 35-74 to study risk factors for breast cancer.

Women who maintain a healthy weight and who have lower perceived stress may be less likely to have chromosome changes associated with aging than obese and stressed women, according to a pilot study that was part of the Sister Study. The long-term Sister Study is looking at the environmental and genetic characteristics of women whose sisters had breast cancer to identify factors associated with developing breast cancer. This early pilot used baseline questionnaires and samples provided by participants when they joined the Sister Study.

Two recent papers published in Cancer Epidemiology Biomarkers and Prevention show that factors such as obesity and perceived stress may accelerate the aging process.

“Together these two studies reinforce the need to start a healthy lifestyle early and maintain it,” said Linda Birnbaum, Ph.D., the director of the National Institute of Environmental Health Sciences (NIEHS), part of the National Institutes of Health. The researchers who published these papers are from the NIEHS which sponsors the Sister Study.
