Several factors influence the burden of illness, including:
1. Socioeconomic status: Lower-income populations often experience higher rates of illness due to limited access to healthcare, poor living conditions, and higher levels of stress. 2. Environmental factors: Pollution, climate change, and unsafe living conditions can exacerbate health issues. 3. Behavioral factors: Lifestyle choices such as smoking, diet, and physical activity directly impact the prevalence of chronic diseases. 4. Healthcare accessibility: Availability and quality of healthcare services play a significant role in disease prevention, management, and treatment outcomes.
