Which statement about preventable diseases is accurate?

Preventable diseases refer to health conditions that can be avoided through specific actions, including lifestyle changes, vaccination, or public health interventions. The statement that, "Preventable diseases can often be managed through lifestyle changes," accurately reflects the understanding that many diseases, such as type 2 diabetes, cardiovascular diseases, and certain cancers, are influenced by personal choices regarding diet, physical activity, and other lifestyle factors. By making healthier choices, individuals can significantly reduce their risk of developing these conditions or even manage existing ones more effectively.

In contrast, the notion that all diseases are preventable is overly broad, as some diseases arise from genetic factors or environmental exposures that cannot be completely avoided. The idea that preventable diseases are solely immune-related is misleading, as many have non-immune-related causes, such as lifestyle factors or environmental influences. Lastly, the claim that preventable diseases do not require any intervention is inaccurate; preventive measures, whether through lifestyle changes or medical interventions, are crucial for reducing the incidence of these diseases. Thus, the emphasis on lifestyle changes as a management strategy for preventable diseases makes the selected statement the most accurate.
