Final answer:
The population health approach is necessary to promote health and wellness by considering social, economic, and environmental factors that influence health outcomes. It addresses health inequities and aims to improve health for everyone.
Step-by-step explanation:
The population health approach is needed to promote health and wellness because it takes into account the social, economic, and environmental factors that influence health outcomes for entire populations. By looking at the broader determinants of health, such as access to healthcare, education, and safe environments, the population health approach aims to address health inequities and improve health for everyone.
For example, a population health approach might involve implementing policies to reduce pollution in a community, providing education and resources for healthier lifestyle choices, and ensuring equal access to healthcare services. By addressing these factors at the population level, the goal is to improve overall health outcomes and reduce health disparities. Roberson (2021) explains that improving health disparities requires sustainable efforts to address issues such as health education and health literacy, which can lead to better health outcomes for individuals and families.
