Many factors influence the health of an individual. Recent studies show that these do not only include physiological factors, but where an individual lives, what they believe in, and their financial status. When it comes to marginalized and vulnerable populations, these unexpected influences of overall health are even more profound. For instance, some cultures may hold the belief that immunizations are unsafe, therefore, increasing their susceptibility to disease. On the other hand, some populations may have a lower income, and are unable to afford adequate healthcare and screening, which increases their chance of developing complications in their health. Environmental factors that contribute to an overall decline in health among a population may include unsafe drinking water, hot climates, or exposure to high levels of metal in the air. All of these factors have a notable negative effect on the communities who are exposed.

Education is by far the most important implementation that can be put into effect in order to resolve healthcare disparities. Educating marginalized populations will increase the likelihood of their individuals to understand the importance of healthcare and utilize the tools they do have to protect their health. Furthermore, educating less vulnerable populations about the issues they may not even know about may implement change and provide support to those in need. Not only is teaching imperative, but it is also important to apply the concept of enhancing care in diverse populations into nursing practice. For example, understanding where an individual is from may help a nurse or healthcare worker to a diagnosis faster. This will result in faster treatment and overall better health.
