Key takeaways

People with Type 1 diabetes who maintained a BMI between 18.5–25 or 25–30 had significantly lower cardiovascular disease risk compared to those outside these ranges
A healthy diet and adequate sleep duration were independently associated with reduced heart disease risk in this population
The combination of multiple healthy lifestyle factors—smoking avoidance, moderate alcohol use, healthy weight, good diet, physical activity, and sleep—offered the strongest protection against cardiovascular events
Over 14 years, lifestyle factors were linked to reduced risk of coronary heart disease, heart failure, and stroke in people with Type 1 diabetes

Why This Matters for Type 1 Diabetes

Heart and blood vessel disease remain serious complications for people with Type 1 diabetes. While researchers know that healthy lifestyle habits help protect heart health in the general population, there has been less specific research on whether these same benefits apply to people with Type 1 diabetes. A new prospective cohort study published in Diabetology & Metabolic Syndrome examined this question using data from over 1,300 people with Type 1 diabetes.

What the Study Found

Researchers followed participants for a median of 14.38 years and documented 455 cardiovascular disease events, including coronary heart disease, heart failure, and stroke. They examined six lifestyle factors: smoking status, alcohol consumption, body mass index (BMI), diet quality, physical activity, and sleep duration.

Three individual factors showed independent associations with lower cardiovascular disease risk: maintaining a BMI between 18.5–25 kg/m² or 25–30 kg/m² (compared to other ranges), adhering to a healthy diet, and getting adequate sleep. When participants combined multiple healthy behaviors—creating a lifestyle score of 4–6 factors—they had substantially lower risk of cardiovascular disease overall and specifically for coronary heart disease and stroke.

What This Means

This study suggests that the lifestyle changes recommended for general cardiovascular health may also benefit people with Type 1 diabetes. The findings support a comprehensive approach: maintaining a healthy weight, eating well, getting enough sleep, staying physically active, not smoking, and limiting alcohol use all appeared to work together to reduce heart disease risk.

This is observational research, meaning it shows associations rather than proving cause and effect. Individuals with Type 1 diabetes should discuss any lifestyle changes or health goals with their healthcare team, who understand their complete medical picture and individual needs.
