An intermittent, low-carbohydrate diet was superior to a standard, daily calorie-restricted diet for reducing weight and lowering blood levels of insulin, a cancer-promoting hormone, according to recent findings. Researchers at Genesis Prevention Center at University Hospital in South Manchester, England, found that restricting carbohydrates two days per week may be a better dietary approach than a standard, daily calorie-restricted diet for preventing breast cancer and other diseases, but they said further study is needed.
Obesity is associated with worse outcomes overall in early-stage breast cancer, researchers reported at the 2011 CTRC-AACR San Antonio Breast Cancer Symposium, held Dec. 6-10, 2011. Obesity was linked to shorter time to recurrence (TTR), disease-free survival (DFS) and overall survival (OS). The exception was treatment with endocrine therapy (mainly tamoxifen), in which obesity was associated with a protective effect.
Having diabetes or being obese after age 60 significantly increases the risk for developing breast cancer, a Swedish study has revealed. Data also showed that high blood lipids were less common in patients when diagnosed with breast cancer, while low blood lipids were associated with an increased risk. Researchers of the study also looked at overall cancer incidence and discovered that use of one diabetes drug was associated with a lower rate of any cancer, while another was associated with an increased risk.
Contrary to claims that United States’ presidents age at twice the normal rate, a new study finds that most U.S. presidents live longer than expected for men of their same age and era. The research letter, by noted University of Illinois at Chicago demographer S. Jay Olshansky, is published in the Dec. 7 issue of JAMA, the Journal of the American Medical Association.
A new analysis of national survey data finds that less than one-quarter of parents of overweight children recall ever being told by a doctor or other health care provider that their children were overweight. And although that percentage has increased over the last 10 years, more improvement is needed, said Eliana M. Perrin, MD, MPH, associate professor in the University of North Carolina at Chapel Hill School of Medicine, pediatrician at North Carolina Children’s Hospital, and lead author of the study.
State and school district-level policies mandating minimum requirements for in-school physical education and recess time are associated with increased odds of schools in those states and districts meeting physical activity recommendations for students, according to a report published Online First by Archives of Pediatrics & Adolescent Medicine, one of the JAMA/Archives journals.
A recent study of obese and non-obese children found that low vitamin D levels are significantly more prevalent in obese children and are associated with risk factors for type 2 diabetes. This study was accepted for publication in The Endocrine Society’s Journal of Clinical Endocrinology & Metabolism (JCEM).
A recent study of obese volunteers participating in a 12-week dietary weight-loss program found that successful weight losers had significantly higher resting nerve activity compared to weight-loss resistant individuals. The study was accepted for publication in The Endocrine Society’s Journal of Clinical Endocrinology & Metabolism (JCEM).
