Diabetes continues to be a significant public health issue in California, affecting millions of residents across diverse communities. Understanding the latest statistics is crucial for tailoring effective prevention and treatment strategies.

• Type 2 Diabetes: The vast majority, around 90-95%, of diabetes cases in California are type 2, which is often linked to lifestyle factors such as diet and physical activity.

Impact on Different Demographics

• Age: The prevalence of diabetes increases with age, with nearly 25% of adults aged 65 and older in California living with the condition.

Mortality and Complications

• Annual Deaths: In 2023, diabetes was the seventh leading cause of death in California, contributing to over 9,000 deaths annually.

Economic Impact

• Healthcare Costs: The direct medical costs for treating diabetes in California exceeded $27 billion in 2023. This includes expenses related to hospital care, medications, and diabetes management supplies.

Prevention and Risk Factors

• Obesity: Over 70% of adults with type 2 diabetes in California are overweight or obese, highlighting the significant role that obesity plays in the development of the disease.
• Lifestyle: Poor diet, lack of physical activity, and smoking are prevalent risk factors contributing to the rise in diabetes cases across the state.
• Socioeconomic Disparities: Low-income communities in California experience higher rates of diabetes, often due to limited access to healthy foods, healthcare, and diabetes education.

Conclusion

The 2023 statistics underscore the urgent need for continued efforts in diabetes prevention, education, and access to healthcare in California. Targeted interventions, particularly in high-risk communities, can help curb the growing prevalence of this disease and reduce its long-term impact on public health.
