The 20-year (19997-2017) observational mortality-rate analysis reveals obesity’s impact on longevity for all US age-groups. This project compared the mortality-rate trends where obesity (or overweight) was listed as a causative or contributory factor in death, to cases where cancer (neoplasms), cardiovascular disease, and diabetes, are primary underlying contributory factors. The analysis showed that the general trend of deaths by diabetes, neoplasms, and diseases of the circulatory system has been progressively decreasing nationally; however, a significantly higher trend in mortality rates is observed for the Black or African American populations. Furthermore, over the 1997-2017 observational period, the crude mortality rates for the 45-54 (middle-age) and lower age-groups are below national mortality rate averages but are troublingly increasing for diabetes.
