Final answer:
The question concerns the common risk factors for noninfectious diseases such as cardiovascular diseases and type 2 diabetes, with most individuals aged 20+ having at least one. These include age, genetics, and lifestyle choices like smoking, unhealthy diet, and physical inactivity. Some risk factors are unmodifiable, but many, like obesity and physical inactivity, can be managed through lifestyle changes.
Step-by-step explanation:
The question pertains to the risk factors that 9 out of 10 individuals aged 20 years or older have at least one of, and 2 out of 5 have three or more. These risk factors are common contributors to various noninfectious diseases, particularly cardiovascular diseases and type 2 diabetes. The shared risk factors include but are not limited to age, genetics, and behaviors like smoking, unhealthy diet, and physical inactivity. These behaviors contribute significantly to metabolic syndrome, which is a cluster of conditions—increased blood pressure, a high blood sugar level, excess body fat around the waist, and abnormal cholesterol levels—that occur together, increasing your risk of heart disease, stroke, and diabetes.
Unmodifiable risk factors such as family history of cardiovascular diseases and aging are significant, with the risk of cardiovascular diseases increasing with each passing decade of life. Moreover, certain risk factors like high blood pressure and high blood triglycerides can be managed with medications, while others like obesity and physical inactivity can be managed through lifestyle changes. It's also important to recognize that cardiovascular disease risk triples if parents had the condition, and social determinants like income, education, and employment status play a role. Understanding these risk factors is crucial for prevention and management of such diseases.
