Increased Waist Size Linked to Higher Mortality Risk in Older Women
Larger waist size in postmenopausal women is associated with increased risk of death, highlighting the importance of measuring waist circumference alongside BMI for better health risk assessment.
Recent international research highlights the significance of waist circumference as a predictor of mortality among postmenopausal women aged 50 to 79. Over a span of more than two decades, the study found that women with larger waistlines face a substantially higher risk of death, even when their BMI is accounted for. Specifically, incorporating waist measurements alongside BMI offers a more precise assessment of health risks than relying solely on BMI.
The research, conducted using data from the Women's Health Initiative involving over 139,000 women, developed models to evaluate mortality risk based on BMI and waist size. Findings revealed that women with greater waist circumference, as defined by BMI-specific thresholds, exhibit increased mortality rates across all BMI categories. Notably, women classified as normal weight or overweight with large waistlines had similar risks to women with obesity, emphasizing the importance of waist measurement.
These results bolster current guidelines recommended by the International Atherosclerosis Society and the International Chair on Cardiometabolic Risk, advocating for routine waist circumference measurement during health screenings. The goal is to better identify high-risk individuals and improve preventive strategies.
Overall, integrating waist circumference with BMI enhances risk stratification and can lead to better health outcomes for postmenopausal women, particularly those with overweight or obesity. The study underscores the need for clinicians to consider both measurements for a comprehensive understanding of patients' health risks.
