1. What are the three core functions of public health and how do they relate to population health? (3 points) Answer: The three core functions of public health are assessment, policy development, and assurance. Assessment involves collecting and analyzing data on the health status and needs of a population. Policy development involves creating and implementing plans and interventions to address those needs. Assurance involves ensuring that the policies are effective and that the population has access to quality health services and resources. 2. What are some of the social determinants of health and how do they affect population health outcomes? (3 points) Answer: Social determinants of health are the conditions in which people are born, grow, live, work, and age that influence their health and well-being. Some examples are income, education, employment, housing, environment, culture, and social support. These factors can affect population health outcomes by creating disparities and inequities among different groups of people in terms of their exposure to risk factors, access to health care, and quality of life. 3. What is the difference between primary, secondary, and tertiary prevention and give an example of each in the context of population health? (3 points) Answer: Primary prevention aims to prevent disease or injury before it occurs by reducing or eliminating risk factors. An example is immunization against infectious diseases. Secondary prevention aims to detect and treat disease or injury early before it causes serious complications or disability. An example is screening for cancer or diabetes. Tertiary prevention aims to reduce the impact and consequences of disease or injury by providing rehabilitation and palliative care. An example is physical therapy for stroke survivors or hospice care for terminally ill patients.
