Waist-to-Hip Ratio & Body Adiposity Are Viable Cancer Survival Tools
In a cohort study published by JAMA Oncology on June 4, 2021, of 1,891 Black breast cancer survivors, higher waist-to-hip ratio and body adiposity at approximately 10 months after diagnosis were associated with significantly worse overall and breast cancer cancer-specific survival.
The New Jersey State Cancer Registry was used to identify women living in 10 counties in New Jersey recruited from March 2006 to February 29, 2020, and followed up until September 2, 2020.
This study’s findings suggest 'although measurements using dual-energy x-ray absorptiometry or computed tomography may be ideal when evaluating the association of body composition with breast cancer prognosis, the findings of the present study suggest that simple measures of central obesity (waist circumference and WHR) and body composition (percent body fat and FMI using a portable bioelectrical impedance analysis scale) are clinically useful tools for identifying Black breast cancer survivors at higher risk of death.'
These findings may be particularly relevant for primary care physicians, who are typically responsible for the long-term care of breast cancer survivors and clinical settings with limited resources.
