Inactivity in Seniors With Prediabetes Ups Type 2 Risk
For older adults with prediabetes, a period of temporary inactivity—during illness or injury, for instance—can raise the risk of developing type 2 diabetes. In a study, 22 overweight adults ages 65 to 79 with prediabetes reduced their usual activity levels to less than 1,000 steps a day for 14 days and then returned to their normal activity level of about 7,000 steps per day for two weeks. Oral glucose tolerance tests showed that they were more insulin resistant after the inactivity and didn’t return to normal even two weeks later. (Because of the short length of the study, it’s unclear whether levels might have eventually returned to normal—or progressed to type 2.) Maintain your activity levels as much as possible and discuss with your doctor options for blood glucose management when you can’t be active.
