What are Chronic Diseases?

Long-term health conditions, often referred to as chronic diseases, present a significant challenge due to their complexity and the range of risk factors associated with them. The onset of symptoms can be slow, often requiring substantial adjustments in a person's lifestyle and affecting their self-perception. These diseases, although manageable to an extent, are typically not curable, thereby posing potential threats to lifespan and overall quality of life. In fact, they account for 70% of all deaths in the U.S., with conditions such as chronic back pain and depression having profound effects on individual productivity and the broader healthcare system. Globally, chronic diseases are the biggest cause of premature death, even in regions where infectious diseases are widespread (6).

Risk Factors and Contributing Factors for Chronic Diseases

According to the WHO, the key risk factors for chronic diseases comprise of tobacco use, harmful alcohol use, high blood pressure, physical inactivity, elevated cholesterol, obesity, unhealthy diet, and increased blood glucose levels. These risk factors fall into various categories, such as background factors (e.g., age, sex, educational level, genetics), behavioral factors (e.g., unhealthy diet, tobacco and alcohol use, lack of physical activity), and intermediate factors (e.g., high blood pressure, obesity, high lipid levels, diabetes). In addition, socio-economic conditions, environmental factors, cultural practices, and urbanization at a community level can also play a significant role in affecting health outcomes. While some risk factors are unchangeable, many behavioral and intermediate biological factors can be modified (11, 12).

Importance Of Early Detection And Prevention of Chronic Diseases

Population health screenings can help detect early signs of prediabetes, diabetes, chronic kidney disease, and colorectal cancer, providing an opportunity for prompt treatment that can prevent disease progression. For chronic diseases like cancer, diabetes, and cardiovascular disease, early detection can lead to more effective treatments and longer survival, providing an argument for embedding such examinations in public health programs despite the associated costs. However, the philosophy of "early detection offers the best chance of cure" should be applied judiciously. Some health conditions may resolve over time without intervention, and invasive testing might pose unnecessary risks and anxiety. While there are conditions where early detection and treatment dramatically improve outcomes, like breast and colon cancer, there are others where the benefits are less clear and may result in overtreatment.

Machine learning techniques offer innovative ways to predict these diseases with remarkable accuracy of up to 99.67%. Algorithms are also applied to accurately predict diseases based on patients' symptoms and lifestyle factors. Key to this approach is data mining (the analysis of large sets of data), which enables the extraction of meaningful patterns from health data, thereby aiding early detection (23). 

Examples Of Successful AI Models In Chronic Disease Prediction

AI has already made real-world strides in chronic disease prediction. For instance, a study that focused on four major chronic diseases—diabetes, hypertension, hyperlipidemia, and cardiovascular disease—successfully developed predictive models using common data models (CDM) and machine learning techniques. These models achieved over 80% accuracy in predicting the occurrence of these diseases within a ten-year period, showcasing the potential for preemptive management of chronic disease. Machine learning also has transformative potential in primary care, such as pre-operative care and screening. For example, these algorithms can analyze patient data to identify factors that increase the risk of worsened health outcomes, allowing for personalized and optimized treatment plans. Moreover, global tech companies like Google and IBM have made remarkable advancements in this area, with projects such as Google's DeepMind Health and IBM's Watson demonstrating successful applications of AI in healthcare, offering sophisticated predictive models and diagnostic tools.
