1. Compare the incidences of diabetes within each region of the U.S. for the past year and identify which state has the highest burden of this disease.

According to the Centers for Disease Control and Prevention (CDC) (2012), there are 25.8 million people, or 8.3% of the U.S. population, living with diabetes. 18.8 million people have been diagnosed with diabetes while 7.0 million remain undiagnosed. During a period of 1994 until 2011, (Centers for Disease Control and Prevention, 2011) the prevalence of diagnosed diabetes has increased across the states in the United States. In 1994, twenty-five states had prevalence less than 4.5%, twenty-four states had prevalence of 4.5%–6.0%, and only one state had prevalence greater than 6.0%. In 2010, all states had prevalence greater than 6.0%, fifteen of these exceeded 9.0%. The eastern United States had a much higher prevalence than the western states. The south continues to have many more occurrences than the rest of the county. The southeastern quadrant of the United Sates appears to lead the way with morbidity issues. For example, the southeastern portion of the US is known as the Bible belt because of its socially conservative evangelical Protestantism. Sadly, it is also known as the stoke belt and is considered a part of stroke ally by public health authorities for having an unusually high incidence of stroke and other forms of cardiovascular disease. Multiple studies have shown (Jorgensen, 1994) that people with diabetes are at greater risk for stroke compared to people without diabetes -- regardless of the number of health risk factors they have. Age-standardized diabetes prevalence (Goodarz, Friedman, Oza, Murray, & Ezzatil, 2009) was highest in Mississippi, West Virginia, Louisiana, Texas, South Carolina, Alabama, and Georgia (15.8 to 16.6% for men and 12.4 to 14.8% for women). Vermont, Minnesota, Montana, and Colorado had the lowest prevalence (11.0 to 12.2% for men and 7.3 to 8.4% for women). As of 2011 (United Health Foundation, 2011) using a scale of one to fifty with one being the best Alabama raked fifty with highest instances of those diagnosed with diabetes. Mississippi is forty-nine and was fiftieth in 2010. 2. Analyze and explain the modifiable and stable characteristics in which morbidity and mortality rates can be observed. Include biological or genetic factors associated with any disparities.
Fleeming (2008) explained each person has characteristics and behaviors that give them a predisposition for having certain diseases or being more or less likely to develop them in the future. The factors (Fleeming , 2008) can be broadly categorized into those that are modifiable which include but are not limited to behaviors such as eating and drinking in excess, smoking, and socioeconomic status. Illustrations of unmodifiable or stable characteristics (Fleeming , 2008) are gender and race. Age is unmodifiable but progressive.
Harvard Medical School (Havard Medical School, 2012) published a report that that indicated Heart disease is the leading cause of death among women — and one of the most preventable. In a survey conducted by the American Heart Association, about half of the women interviewed knew that heart disease is the leading cause of death in women, yet only 13% said it was their greatest personal health risk. Other survey data suggest that on a day-to-day basis, women still worry more about getting breast cancer — even though heart disease kills six times as many women every year. Heart disease in women in often misdiagnosed because the symptoms present themselves differently in women and the systems are often attributed to stress, panic, and even hypochondria. Racial makeup is a (Fleeming , 2008) characteristic associated with different patterns of disease and mortality. This position has all but eliminated the view that race has no bearing on disease. A (Wade, 2012) study done by the geneticist, Dr. Neil Risch of Stanford University, says that genetic differences have arisen among people living on different continents and that race, referring to geographically based ancestry, is a valid way of categorizing these differences. For example, (Childerhose, 2008) Ashkenazim Jews (of European descent) are more inclined to have Tay-Sachs disease, while cystic fibrosis haunts White people. Latin Americans and African rooted people are particularly vulnerable to type 2 diabetes, 90% and 60 % more than White people. Hypertension plagues Afro-Caribbean descent at a higher rate than other populations.
With age a plethora health related issues can ensue. Some are very mild morbidity issues and others can lead to mortality. As (Rattan & Kassem, 2006) a biosocial issue, aging is the underlying basis of almost all major human disease, such as atherosclerosis, cancer, cardiovascular defects, cataract, diabetes, dementia, muscular degeneration, neurodegeneration, osteoporosis and sarcopenia. There are any number of modifiable and well as unmodifiable things associated with how one ages and life expectancy such as education, access to healthcare, environment and, race, sex and genes. 3. Suggest how the incidence and prevalence of diabetes varies across dimension of time, both in the short and long term.

Mortality rates associated with diabetes (Fleeming , 2008) can be compared across time, place or population groups, which are the dimensions from which epidemiologist describe important patters and make inference regarding risk factors, disease, and longevity.
Based on the rate of diagnosed cases of diabetes researchers are predicting (UnitedHealth Center for Health Reform & Modernization, 2010) diabetes will be an epidemic and will affect half of the US by 2020. The research found that by 2020 fifteen percent of adults will have diabetes and thirty-seven percent will have prediabetes, compared with twelve percent and twenty-eight percent today, respectively. Because the risk of diabetes increases due to poor nutrition and lack of physical activity, the report by UnitedHealth Center for Health Reform & Modernization (2010) suggest Enrolling adults with prediabetes in the Diabetes Prevention Programs. Intensive lifestyle intervention utilizing community-based coaches, a data-driven tracking system, and a large network of YMCA and both public and private could potentially reduce the number of individuals who move from prediabetes to diabetes by three million by the end of the decade.
In a report issued by the CDC (Centers for Disease Control and Prevention, 2011) showed the trend in diagnosed diabetes among people of all ages in the United States from 1958 through 2010. The percentage with diagnosed diabetes increased from 0.93% in 1958 to 6.95% in 2010. In 2010, 21.1 million people had diagnosed diabetes, compared to only 1.6 million in 1958. There were a number of years that no statistics were kept which may account for lack of concern for diabetes becoming a growing health risk. 4. Propose the risk factors and causes associated with diabetes, as well as the means or methods of transmission, based on short-term and long-term trends.
The US National Library ( (PubMed Health , 2012) of Medicine states diabetes can be caused by too little insulin, resistance to insulin, or both. Diabetes affects more than 20 million Americans. Over 40 million Americans have pre-diabetes which often comes before type 2 diabetes. The disease is not communicable, that is, transmitted person-to person. According to the (American Diabetes Association, 2011)American Diabetes Association (ADA), 25.8 million adults and children in the United States have diabetes. 18.8 million have been diagnosed, 7.0 million are undiagnosed, 79 million are prediabetes while 1.9 million new cases of diabetes are diagnosed in people age twenty years and older in 2010.
Concerning morbidity and mortality the ADA (American Diabetes Association, 2011)sites in 2007, diabetes was listed as the underlying cause on 71,382 death certificates and was listed as a contributing factor on an additional 160,022 death certificates. This means that diabetes contributed to a total of 231,404 deaths. There are many known complications associated with diabetes such as cardiovascular disease, hypertension, loss of sight, kidney disease and amputation of limbs. Medical cost associated diabetes was more than $174 billion on 2006 according to the ADA. 5. Analyze and explain how Diabetes Technology During the Past 30 Years: A Lot of Changes and Mostly for the Better has changed in the past 50 years and what this tells you about the causes of the disease. During the past 50 years, the (Deeb, 2012)management of diabetes has seen changes in glucose measurement, insulin administration, and types of insulin with the result being an improvement of the lives of those living with diabetes. With all of the advances in technology and medicine one would tend to believe the rate and incidences of the disease would decline but the statistics show a different outcome. According to the CDC (Centers for Disease Control and Prevention, 2011) in 1962 1.6 percent or 192 million people of U.S. population with diagnosed diabetes. By 2010, which is the latest data available 6.95 percent or 21.13 billion were diagnosed with this disease. A new CDC report predicts that the number of new diabetes cases each year will increase from eight per 1,000 people in 2008, to 15 per 1,000 in 2050.
Several factors have been the catalyst for an increase in diabetes in the US. (Centers for Disease Control and Prevention, 2011) The aging population, an increase in minority groups and obesity, being the leading cause. Obesity is most likely the most prevalent cause in insulin resistance. Over the last 50 years the US economy has seen many more years of economic prosperity and advancement in technology that has removed the need for most task requiring manual labor therefore less physical activity was needed. Increased salary has also translated into increased waistlines resulting in obesity.
The same could also apply during recession as poor people attempt to budget they will purchase what is most cost effective in order to feed more people. While health professionals encourage the consumption of fresh fruit, vegetables, wholegrain, and non-processed food the cost of these items can be a challenge for those with limited funds. Food choices contribute the weight and overall health. Those without healthcare living with undiagnosed diabetes maybe making choices that are detrimental to their health.
6. Identify diabetes patterns across the U.S and within specific areas and formulate a theory for this pattern. CDC scientists (Centers for Disease Control and Prevention, 2011) have identified a diabetes belt located mostly in the southern portion of the United States. The diabetes belt consists of 644 counties in 15 states. The CDC also reported states with a portion of their counties in the diabetes belt are Alabama, Arkansas, Florida, Georgia, Kentucky, Louisiana, North Carolina, Ohio, Pennsylvania, South Carolina, Tennessee, Texas, Virginia, and West Virginia. The entire state of Mississippi is included in the belt. Sadly, the southeaster portion continues to be one of the unhealthiest places to live being a part of the stroke belt, the obesity belt, as well as the diabetic belt. New England outranked the Mid-West, West, and South with six of its states falling into the healthiest category. A proposed theory for this pattern has to do with behavior, race, and socioeconomic status. Mississippi has been recognized as the unhealthiest state in the US. This is because the most chronically ill, poorest, and uneducated in the nation reside there. According to a study done by WebMD (Martin, 2012) Mississippi has an obesity rate of 34.9%. Four out of 10 Mississippi high school students drink at least one sugary soda a day, and the state’s adults were most likely to be physically inactive. This is a stark contrast to states such as Vermont and Oregon that have been touted as healthiest states because of the residence access to parks, walking trails and propensity for exercise and leading healthier lifestyles. Mississippi is also the most impoverished state. About (Kaiser Family, 2011) 57% of Mississippians live at or below the poverty line. Out of that 15% of it white citizens and 42% of blacks are living in poverty. This is as astronomical number because black citizens only make up 37% of Mississippi’s population. The median income in Mississippi is $39,078 whereas the national average is $50,443 with an unemployment rate of 9.2%, which is 1.4% higher than the national average. Social service programs such as Medicare provide health care for those over 65 or have a disability. Medicare and other state programs such as Children’s Health Insurance Programs (CHIP) offer coverage for children of low-income parents. As of the 2010 US Census (Kaiser Family, 2011) 23% of adult Mississippians had no insurance and little access to healthcare. This may account for so many undiagnosed cases of diabetes and cardiovascular issues.

...Epidemiology Paper Allison Brown Nur 408 May 14, 2012 Prof. Pamela Orr Epidemiology Paper People have many health concerns and diagnosis that presents to the current public health as daunting. The first step in any medical situation regarding a person’s health is prevention that is talked among the professionals in the health community. This will be the only way to help the cycle to break that will further prevent other diseases from occurring. Using epidemiology and the epidemiology triangle diabetes in African Americans will be observed. This health concern in many communities in the United States can be prevented and helped, but information is the key to success. In this paper we will be examining the definition and description of epidemiology, the steps and methods of epidemiology, reviewing the data of the selected population. We will also be looking at the epidemiological triangle as well as various levels of prevention. Epidemiology is the study of the distribution and determinants of health-related states or events (including disease), and the application of this study to the control of diseases and other health problems. Various methods can be used to carry out epidemiological investigations: surveillance and descriptive studies can be used to study distribution; analytical studies are used to study determinants (WHO, 2012).

Epidemiology

...Epidemiology Name: Institution: Course: Tutor: Date: Abstract Descriptive epidemiology is based on two important premises which are central in the field. The first premise states that disease does not occur in isolation. Secondly, patterns of disease occurrence are placed under three important categories of person, place and time. This paper seeks to build understanding on the three areas by giving relevant examples where they are applied. Epidemiology Person In Epidemiology studies the important demographic information will include age, sex, marital status, race, ethnicity, and religion and socioeconomic status. Age is considered the most important factor and is used in analyzing trends in disease occurrence. Advancement in age may be associated with the occurrence of degenerative diseases. The elderly are also linked with several challenges. Changes marking age are shown by two important phases in life which shows greater frequency (Descriptive Epidemiology n.d). Sex as a second determinant of the person, and allows us to make references across sexes. For instance psychological studies have revealed that women cope well in the event of stress than men. Marital status is closer to this, and in epidemiology studies, it can be useful in establishing patterns of chronic diseases across genders (Descriptive Epidemiology n.d). Race and ethnicity have been used in epidemiology studies to show...

...Epidemiology CHF NUR/408 April 1, 2013 Epidemiology Epidemiology is used to help better understand a diseases process, how they work, and how they are transmitted. This helps us to better treat the disease. The process of epidemiology is lengthy but must be followed accurately to ensure correct diagnosis and treatment. Epidemiology is used when a new disease is found and when a disease reappears in high numbers. A common disease in the elderly is congestive heart failure (CHF). The epidemiology process can be used to better understand the disease, what causes it and how to treat it. According to the World Health Organization (WHO), “Epidemiology is the study of the distribution and determinants of health-related states or events (including disease), and the application of this study to the control of diseases and other health problems. Various methods can be used to carry out epidemiological investigations, such as surveillance and descriptive studies that can be used to study distribution and analytical studies are used to study determinants (WHO, 2011). Epidemiology tries to determine what causes disease and what people can do to prevent disease. Epidemiology was first used when scientists tried to discover causes of diseases, such as smallpox and polio (Cornell University, 1993). Epidemiology is no longer limited to transmissible diseases. Epidemiology usually cannot prove a cause of a disease; it can only show certain risk factors...

...Epidemiology Paper In this epidemiological paper, I will be discussing about my chosen vulnerable population of elderly and the disease of type II diabetes among elderly population. I will also be discussing epidemiology and what it means, the steps and methods of epidemiology and how it was done for my chosen population and disease. Ethical and legal considerations, how to provide culturally competent care, and at last, I will discuss whether the research was descriptive or analytical, and the process of feasibility and evaluation of prevention of diseases. As stated in Nursing Standard, epidemiology is a scientific research discipline concerned with observing, measuring and analyzing health-related occurrences in human populations (Last 1995, Trichopoulos 1996). Mausner and Kramer (1985) suggest that epidemiological studies can be applied to all diseases, conditions and health-related events (Whitehead, 2000). Although epidemiology is focused on observing, measuring, and analyzing, it also evaluates diseases and health services, rationalizes resources, and prioritizes as to how to formulate strategies for health promotion. Epidemiology can also help to determine the health of the population, planning of health policies and services, and maintaining a healthy environment for all. When it comes to nursing, epidemiology offers nurses many benefits in incorporating health practices into their professional roles, helps them in having a better understanding in regards to the disease...

...Epidemiology NUR 408 October5, 2015 Epidemiology Epidemiology is the basic principle of public health. According to Hilfinger Messias, McKeown, and Adams (2012, p. 255 ), “Epidemiology has been defined as the study of the occurrence and distribution of health-related states or events in specified populations, including the study of the determinants influencing such states, and the application of this knowledge to control the health problems” (Porta, 2008, p 81). The goal of epidemiology is optimal health for the entire community. It is important to remember that health does not merely mean medical treatment for specific diseases, but also assurance of available services and development and implementation of policies and programs to meet the needs of the population as a whole. Descriptive epidemiology is the study of the “association of health events to person, place, and time” (Stroup, D. & Thacker, S., 2009, p. 262). Analytical epidemiology studies the causes and risk factors of health events. In order to evaluate the health events in a population, both descriptive and analytical epidemiology are important (Stroup, D. & Thacker, S., 2009). Three categories of data sources commonly used in epidemiologic studies including surveillance data, census data, and vital records, data collected for other purposes, and epidemiologic data (Hilfinger Messias, McKeown, and Adams 2012).

Childhood Obesity

...Epidemiology Paper on Childhood Obesity Obesity is a global epidemic affecting millions of the world population. Childhood obesity is especially worrisome as it is linked to higher incidence of health issues in adulthood (Lakshman, Elks, & Ong, 2012). There are many factors to look at when assessing the prevalence of childhood obesity, including culture, socio-economic status, food availability, activity, and genetics. To better understand this problem, it is essential to understand the factors that lead to obesity, how obesity is studied, and what are ways to help reduce the occurrence of obesity. Through epidemiology, this health concern can be better understood and provide the information needed to generate a plan of action to help reduce the risk factors that lead to childhood obesity. Epidemiology is “the study of the occurrence and distribution of health–related states or events and specified populations, including the study of the determinants influencing such states, and the application of this knowledge to control the health problems” (Stanhope & Lancaster, 2012, pg 255). Through epidemiology the questions of who, what, where, when, how, and why can be investigated to offer information about the dissemination or patterns of health measures. The Epidemiological Triangle allows epidemiologists to understand the relationships between agent, host, and the environment when looking at a specific health concern.

...Epidemiology Paper Epidemiology has become the method of choice for public health research. The patterns and trends and cause and effects of health affecting phenomena identified by epidemiology are instrumental in predicting risk factors e.g.; development of treatment strategies to prevent or contain diseases. Epidemiology estimates have changed over time related to changes in the definition and diagnosis of diseases. Epidemiology is practiced as a broad scientific discipline that addresses occurrences of diseases and distribution of health status of populations. Integration of casual concepts at the clinical, social and environmental levels will allow faculty to work to maintain an intellectual environment that will facilitate the integration of biological, social and, analytical approaches of epidemiology. This type of environment allows faculty and students to develop the knowledge to fully appreciate the complexities of biosocial system to understand, modify, and use this information to maximum potential.
