Discussion post: Health promotion strategies

On the Healthy People 2020 website, the 2020 LHI topic, Social Determinants, explains that a national indicator of health is measured by “Students who graduate with a regular diploma 4 years after starting 9th grade” (para. 11). According to the data, as a nation, are we improving or declining, and why is this important to our health as a country?

P.S, please follow the instructions as it asks and answer the question.

I only need half-page and two references from Potter, P, A., Perry book and Scholar article that are less than five years of publication.
