    Seniors with prediabetes should eat better, get moving, but not fret too much about diabetes

    Almost half of older adults — more than 26 million people 65 and older — have prediabetes, according to the Centers for Disease Control and Prevention. How concerned should they be?

    Not very, say some experts. Prediabetes — a term that refers to above-normal but not extremely high blood sugar levels — isn’t a disease, and it doesn’t imply that older adults who have it will inevitably develop Type 2 diabetes, they note.

    “For most older patients, the chance of progressing from prediabetes to diabetes is not that high,” said Dr. Robert Lash, chief medical officer of the Endocrine Society, commenting on recent research. “Yet labeling people with prediabetes may make them worried and anxious.”

    Other experts believe it’s important to identify prediabetes, especially if this inspires older adults to get more physical activity, lose weight, and eat healthier diets to help bring blood sugar under control.

    “Always a diagnosis of prediabetes should be taken seriously,” said Dr. Rodica Busui, president-elect of medicine and science at the American Diabetes Association, which recommends adults 45 and older get screened for prediabetes at least once every three years. The CDC and the American Medical Association make a similar point in their ongoing “Do I Have Diabetes?” campaign.

    Still, many older adults aren’t sure what they should be doing if they’re told they have prediabetes. Nancy Selvin, 79, of Berkeley, California, is among them.

    At 5 feet and 106 pounds, Selvin, a ceramic artist, is slim and in good physical shape. She takes a rigorous hourlong exercise class three times a week and eats a Mediterranean-style diet. Yet Selvin has felt alarmed since learning last year her blood sugar was slightly above normal.

    “I’m terrified of being diabetic,” she said.

    Two recent reports about prediabetes in the older population are stimulating heightened interest in this topic. Until their publication, most studies focused on prediabetes in middle-aged adults, leaving the significance of this condition in older adults uncertain.

    The newest study by researchers at the CDC, published in April in JAMA Network Open, examined data about more than 50,000 older patients with prediabetes between January 2010 and December 2018. Just over 5% of these patients progressed to diabetes annually, it found.

    Researchers used a measure of blood sugar levels over time, hemoglobin A1C. Prediabetes is signified by A1C levels of 5.7% to 6.4% or a fasting plasma glucose test reading of 100 to 125 milligrams per deciliter, according to the diabetes association. (This glucose test evaluates blood sugar after a person hasn’t eaten anything for at least eight hours.)

    Of note, study results show that obese older adults with prediabetes were at significantly heightened risk of developing diabetes. Also at risk were Black seniors, those with a family history of diabetes, low-income seniors, and older adults at the upper end (6%-6.4%) of the A1C prediabetes range. Men were at slightly higher risk than women.

    The findings can help providers personalize care for older adults, Busui said.

    They also confirm the importance of directing older people with prediabetes — especially those who are most vulnerable — to lifestyle intervention programs, said Alain Koyama, the study’s lead author and an epidemiologist at the CDC.

    Since 2018, Medicare has covered the Diabetes Prevention Program, a set of classes offered at YMCAs and in other community settings designed to help seniors with prediabetes eat healthier diets, lose weight, and get more physical activity. Research has shown the prevention program lowers the risk of diabetes by 71% in people 60 and older. But only a small fraction of people eligible have enrolled.

    Another study, published in JAMA Internal Medicine last year, helps puts prediabetes in further perspective. Over the course of 6.5 years, it showed, fewer than 12% of seniors with prediabetes progressed to full-fledged diabetes. By contrast, a larger portion either died of other causes or shifted back to normal blood sugar levels over the study period.

    The takeaway? “We know that it’s common in older adults to have mildly elevated glucose levels, but this doesn’t have the same meaning that it would in younger individuals — it doesn’t mean you’re going to get diabetes, go blind, or lose your leg,” said Elizabeth Selvin, daughter of Nancy Selvin and a co-author of the study. She is also a professor at Johns Hopkins Bloomberg School of Public Health.

    “Almost no one develops the [diabetes] complications we’re really worried about in younger people.”

    “It’s OK to tell older adults with prediabetes to exercise more and eat carbohydrates evenly throughout the day,” said Dr. Medha Munshi, director of the geriatric diabetes program at Joslin Diabetes Center, an affiliate of the Harvard Medical School. “But it’s important to educate patients that this is not a disease that is inevitably going to make you diabetic and stress you out.”

    Many older people have slightly elevated blood sugar because they produce less insulin and process it less efficiently. While this is factored into clinical diabetes guidelines, it hasn’t been incorporated in prediabetes guidelines, she noted.

    Aggressive treatments for prediabetes, such as the medication metformin, should be avoided, according to Dr. Victor Montori, an endocrinologist and professor of medicine at the Mayo Clinic. “If you get diabetes, you will be prescribed metformin. But it’s just nonsense to give you metformin now, because you may be at risk, to reduce the chance that you’ll need metformin later.”

    Unfortunately, some doctors are prescribing medication to older adults with prediabetes, and many aren’t spending time discussing the implications of this condition with patients.

    That was true for Elaine Hissam, 74, of Parkersburg, West Virginia, who became alarmed last summer when she scored 5.8% on an A1C test. Hissam’s mother developed diabetes in adulthood, and Hissam dreaded the possibility that would happen to her too.
