What is one of the main goals of Healthy People 2020?

One of the main goals of Healthy People 2020 is to enhance the length of lives, which aligns with its overarching mission of improving the health of the population. This initiative aims to increase the quality and years of healthy life, thereby focusing on prevention, wellness, and disease management. By setting measurable objectives, Healthy People 2020 emphasizes the importance of reducing illness and enhancing health outcomes, ultimately seeking to promote a longer life span filled with better health.

In contrast to this focus on improving health and longevity, the other options do not align with the goals of Healthy People 2020. Increasing healthcare costs would run counter to the objective of improving health outcomes without placing an undue financial burden on individuals. Promoting sedentary lifestyles contradicts the initiative's encouragement for physical activity as a means to enhance health and well-being. Additionally, reducing accessibility to healthcare opposes the goals of increasing health access and equity, which are central to achieving better public health outcomes.
