Conclusion:This study shows a statistically and clinically significant gap between Whites and Blacks in the use of annual physical examination and preventive care services in the District of Columbia. The results of the study indicate that race (Whites versus Blacks) and work schedule conflicts are not significant factors in the noted gap. The study also found that income and education levels were not significant factors. Moreover, the study demonstrates a knowledge gap between Whites and Blacks pertaining to knowing that critical preventive care services are fully covered by insurance plans (Section 2713 of the Affordable Care Act mandate). This is important because the study indicates that knowing that critical preventive care services are covered by insurance companies is a (small) contributing factor in the difference in the utilization of preventive care services between Whites and Blacks in the District of Columbia. The study found that being prompted by a secondary party (insurance company, medical practitioners, educational material, and healthcare advertisement) is the primary motivation for Whites and Blacks to utilize preventive care services. Habit (self-directed) was ascertained to be the primary motivation for Whites and Blacks to undergo an annual physical examination. The study shows that 94.11% of the residents of the District of Columbia had health insurance coverage during 2017-2020.Background: Despite the benefits of preventive care services and annual physical examinations, studies show that very few adults in the United States undergo an annual physical examination, and fewer utilize vital preventive care services. This study was designed to ascertain the number of adults in the District of Columbia that have utilized annual physical examinations and preventive care service at least once during 2017-2020, and whether a difference in the utilization of annual physical examinations and preventive care service exists between Black and White. This study was also designed to ascertain whether race, work schedule conflict, and knowing that preventive care services are fully covered by healthcare insurance plans are factors in the use of preventive care services in the District of Columbia.
