New York is marking World Diabetes Day on November 14 with blue illumination at public landmarks and a health message centered on screening for prediabetes. The State Health Department says many people with elevated blood sugar do not know it, making a routine risk review and appropriate testing an opportunity to act before type 2 diabetes develops.

A state Behavioral Risk Factor Surveillance System brief found that the share of adults reporting a prediabetes diagnosis increased from 8.8 percent in 2014 to 14 percent in 2024. The department cautions that the rise may reflect both more prediabetes and improved screening. Self-reported diagnosis data should not be interpreted as a complete count of every New Yorker with the condition.

Prediabetes means blood-glucose levels are above the normal range but not yet in the diabetes range. It can increase the likelihood of type 2 diabetes and is associated with risks that include heart, kidney and vascular disease. A diagnosis is made through clinical testing and interpretation, not through symptoms alone or a consumer device used without medical guidance.

Screening decisions depend on age, health history and risk factors. People should discuss testing with a qualified health professional rather than assume that one general recommendation applies to everyone. A normal result does not eliminate future risk, and an abnormal result may need confirmation. The value of screening comes from connecting an accurate result to an appropriate follow-up plan.

Evidence-based lifestyle programs can help some participants reduce risk through sustainable changes in activity, nutrition and weight. New York promotes the National Diabetes Prevention Program, which uses a structured curriculum and trained coaches. The department says the program aims for increased physical activity and, when appropriate, a five-to-seven-percent reduction in body weight.

The prevention program is a covered benefit for eligible New Yorkers enrolled in Medicaid and for Medicare members, according to the state. Coverage rules, provider participation and referral requirements can vary, so patients should verify benefits before enrolling. People who cannot safely increase activity or change diet without supervision should seek individualized clinical advice.

The state estimates that 1.9 million New York adults, or 12.3 percent, have diagnosed diabetes. For people already living with diabetes, the relevant service is not prevention alone. Diabetes Self-Management Education and Support programs can help with medication routines, nutrition, monitoring, problem solving and communication with a care team.

Access is uneven. Communities with fewer primary-care providers, safe places for activity, affordable food options or reliable transportation may face higher barriers to testing and sustained prevention. A public-health strategy therefore needs local programs and coverage as well as individual advice. Measuring enrollment and completion by community can show whether services reach people at greatest risk.

Landmarks scheduled for blue illumination include One World Trade Center, the Governor Mario M. Cuomo Bridge, the Kosciuszko Bridge, Grand Central's Pershing Square Viaduct, Moynihan Train Hall, Niagara Falls and several state facilities. The lighting is symbolic; the actionable part of the observance is helping residents locate screening, prevention and diabetes-management services.

Readers should treat this article as general public-health information, not a diagnosis. Anyone with symptoms of dangerously high or low blood sugar or another urgent condition should seek prompt medical care. For routine questions, the next step is to ask a health professional whether testing is appropriate and to use official program locators when looking for recognized prevention or education services.
