New national guidelines aim to prevent weight gain in middle-aged women. In a new study outlining the clinical guidelines published in the Annals of Internal Medicine, researchers with the Women’s Preventive Services Initiative reviewed data on almost 52,000 middle-aged women. They found that women gain an average of 1.5 pounds per year between 40 and 60 years old, increasing their risk of becoming overweight or obese. Significant weight gain during these years has been linked with cardiovascular disease, hypertension, Type 2 diabetes, fatty liver disease and numerous cancers. With these new guidelines, the researchers hope healthcare providers begin addressing efforts to help women maintain a healthy weight instead of treating obesity once it has set in.
