Executive Summary
The Arkansas Diabetes Prevention and Control Program is funded by the Centers for Disease Control and Prevention to reduce and prevent the burden of diabetes in Arkansas Information on the burden of diabetes in Arkansas is compiled every other year This report is intended to describe the impact of diabetes in Arkansas for program managers, Diabetes Advisory Council members, policy makers, researchers, and other interested parties It is hoped that this information will, provide assistance in determining where interventions are needed The Salient Findings Diabetes has reached epidemic proportions in Arkansas The prevalence of diabetes in Arkansas has been at or above the national average for the past 10 years There was a 35
percent increase in the diabetes prevalence from 1993 to 2002 An estimated 227,000 adult Arkansans had diabetes in 2003 Of those, 151,000 were diagnosed, but it remained undetected and untreated in the rest The prevalence of diabetes increases with age, with the prevalence among persons over the age of 45 being more than four times greater than the prevalence found among younger persons The diabetes prevalence among African Americans 97 is significantly higher than among whites 71 Diabetes is the 6th leading cause of death in Arkansas and the 4th leading cause of death among African Americans In 2003, 5619 hospitalizations were reported among people with diabetes in Arkansas An estimated 73 million was accrued in hospitalization costs for people with diabetes In 2002, 869 lower extremity amputations, 1576 hospitalizations for ketoacidosis, 372 incident cases of chronic end-stage renal disease, and 317 deaths among persons receiving dialysis were attributed to diabetes

Diabetes Mellitus
Diabetes is a disease in which the body does not produce or properly use insulin Insulin is a hormone that is needed to convert sugar, starches and other food into energy needed for daily life1 Diabetes can cause serious health complications including heart disease, blindness, kidney failure, and lower-extremity amputations2 The cause of diabetes continues to be a mystery, although both genetics and environmental factors such as obesity and lack of exercise appear to play roles1 An estimated 182 million Americans, or 63 percent of the US population, have diabetes About two-thirds of these individuals, or 13 million, have been diagnosed with diabetes The remaining third, or 52 million, are unaware that they have diabetes Types of Diabetes: Type 1 Failure of the body to produce insulin Accounts for 5 to10 percent of all cases Type 2 Insulin resistance combined with relative insulin deficiency Accounts for 90 to 95 percent of all cases Gestational diabetes Failure of the body to make and use all the insulin it needs for pregnancy Occurs in 2 to 5 percent of all
pregnant women
Prevalence of Diabetes in Arkansas
Approximately 227,000 Arkansans have diabetes An estimated 74 percent have been told that they have diabetes, which accounts for 151,000 people The other 75,500 remain undiagnosed
5
Diabetes prevalence both in Arkansas and nationwide has increased over the past decade Diabetes prevalence in Arkansas has been above the national median throughout the past decade Diabetes prevalence in Arkansas rose from 58 percent in 1993 to 74 percent in 2003, a 28 percent increase over the 10-year period
Arkansas is in the second highest tier of diabetes prevalence in the nation
6
Diabetes prevalence increases with age The prevalence increases fourfold after the age of 45 The highest prevalence of diabetes is found among people 65 years of age or older Like many other chronic diseases, diabetes can remain undetected for a long time before it is clinically diagnosed
Diabetes disproportionately affects minorities, primarily African Americans, and the prevalence varies by geographic region see Map 1 on page 19 The diabetes prevalence among African Americans is 37 percent higher than the prevalence among
whites
7
Mortality
Diabetes is the sixth leading cause of death in Arkansas and in the US Every year, 300,000 deaths nationally are attributed to diabetes and its complications3
Diabetes mortality has increased both in Arkansas and nationwide over the past decade In 2001, the age-adjusted mortality rate for diabetes in Arkansas was the same as the national rate Diabetes may well be underreported on death certificates as the leading cause of death The CDC estimates that only 4 of 10 deaths among people with diabetes actually have diabetes listed as the cause of death
The diabetes mortality rate for blacks is approximately three times higher than that for whites Most of the deaths among blacks occur prematurely before 65 years of age 6 The diabetes mortality rate also varies by geographic location see Map 2 on page 20

Hospitalizations
The Arkansas Hospital Discharge data system collects in-patient discharge information from all Arkansas hospitals Based on the data, the number of hospital discharges with primary diagnosis of diabetes has been increasing over the past 5 years
More than 5600 discharges were reported in 2003 There has been a 20 percent increase in
hospital discharges with primary diagnosis of diabetes in the 5-years since 1999
During the same period, the average length of diabetes-related hospital stays increased, reaching a high of 56 days in 2002 There was a subsequent decrease in 2003 to 53 days The reason for this pattern is not known
The costs due to diabetes include direct medical costs such as physician visits, hospitalizations, and pharmacy charges, as well as indirect costs, such as lost days of work, disability, and premature deaths Data are not available to estimate the indirect costs The direct medical costs due to hospitalizations are estimated from the Arkansas Hospital Discharge data system, although these estimates do not include outpatient costs 9
There has been a significant increase in total hospitalization charges due to diabetes in Arkansas These charges increased from 55 million in 2001 to 73 million in 2003, a 33 percent increase
The average hospitalization charges increased 55 percent from 1999 to 2003
The age-adjusted hospitalization rate for diabetes is significantly higher among blacks compared to whites This may be due to the higher diabetes prevalence and fewer preventive care
practices among blacks
10
Complications
Diabetes can cause serious complications like heart disease, kidney disease, eye disease, foot problems, dental disease, pregnancy related complications and diabetic ketoacidosis
25 percent of the people admitted to Arkansas hospitals for ischemic heart disease also had a diagnosis of diabetes 72 percent of all lower extremity amputations performed during 2001 were performed on persons with diabetes
In 2002, diabetes accounted for: 869 lower extremity amputations 1576 hospitalizations for ketoacidosis 2939 hospitalizations for diabetic retinopathy see Map 5 on page 23 372 incident cases of chronic end-stage renal disease 317 deaths among persons receiving dialysis
Good glucose control has been shown to prevent many of these complications5
11
Risk Factors
Prevention is the key to halting the unfolding diabetes epidemic Identification of the risk factors among the population and promotion of primary prevention measures are the first steps The risk factors associated with a person developing diabetes can be classified as either modifiable4 risk factors such as obesity and physical inactivity, or non-modifiable risk factors such as age,
race and family history of diabetes
Approximately one fourth of adults in Arkansas are obese, 29 percent are physically inactive and only 21 percent consume the recommended five servings of fruits and vegetables a day 25 percent of adults in Arkansas are current smokers Tobacco use increases cardiovascular complications for people with diabetes
14 percent of Arkansas youths are overweight; 34 percent of youths are involved in insufficient physical activity Only 1 in 5 of the Arkansas youths consume the recommended five servings of fruits and vegetables a day More than one third of them are current smokers
12
Figure 16 shows the racial differences among factors that increase the likelihood of a person developing diabetes
The prevalence of obesity is 42 percent higher in blacks compared to whites The prevalence of physical inactivity is 21 percent higher in blacks compared to whites A lower proportion of black adults consume the recommended five or more fruits and vegetables a day compared to white adults The proportion of current smokers was about the same in blacks and whites
Research has shown that lifestyle changes can prevent or delay the onset of type 2
diabetes among high-risk adults The Centers for Disease Control and Prevention recommend the maintenance of a healthy diet 5 or more servings of fruits and vegetables a day, reduced fat and sugar intake and moderate physical activity 30 minutes a day, 5 days a week for all adults The Diabetes Prevention Program, a large prevention study of people at high risk for diabetes, showed that the risk of developing diabetes could be reduced by 58 percent over 3 years by following the recommended lifestyle modifications
13
Access to Health Care
Lack of health care access is a problem faced not only by people with diabetes but also by many Arkansans generally Poor health consequences among people with diabetes can be secondary to limited availability of preventive services such as professional eye exams and foot exams
Barriers to health care access may include: Financial Barriers Structural Barriers Personal Barriers Financial Barriers Lack of health insurance is a major financial barrier It differs among different racial/ethnic groups in Arkansas
A greater proportion of minorities lack health insurance compared to whites
14
S
tructural Barriers Approximately 22 percent of the
states population lives in areas designated as Health Profession Shortage Areas HPSAs by the federal government More than half of the states population live in areas designated as Medically Underserved Areas MUAs
In Arkansas, the Southeast and Southwest Public Health Regions have fewer health care professionals compared to other public health regions However this is not adjusted for population size
Personal Barriers Even in the presence of health care infrastructure, personal barriers, such as lack of knowledge or trust in the system, could pose barriers to health care access Promoting awareness and education among the general public regarding access to health care services is the key to eliminating this barrier
15
Preventive Care Practices
The Centers for Disease Control and Prevention and the American Diabetes Association have set national objectives for preventive care practices among people with diabetes Following the recommended guidelines, which address receiving annual eye exams, foot exams, HbA1c checks, and flu and pneumonia vaccinations, has been shown to reduce the costs associated with complications of diabetes and also improves the quality of life among people
with diabetes 1,2
Only 56 percent of people with diabetes report having received a flu shot in the past year Only 43 percent report having ever received a pneumonia vaccination 63 percent reported they had received a dilated eye examination and fewer still 58 reported receiving a foot examination by a health care provider
The guidelines also recommend daily blood glucose checks and foot checks for the people with diabetes
Only 78 percent reported checking their feet daily for any sores or irritations Less than three-fourths checking their blood glucose daily
16
There were racial differences in preventive care practices among people with diabetes According to the Behavioral Risk Factor Surveillance Survey BRFSS:
Fewer blacks 69 received HbA1c tests in the past year than whites 88 Fewer whites 57 received foot exams by a professional than blacks 69 Fewer blacks 58 received dilated eye exam in the past year than whites 62 Fewer blacks 23 received flu shot in the past year than whites 40 Fewer blacks 18 ever received pneumonia vaccination than whites 21
There were racial differences even among the patient-completed preventive care practices
Fewer whites 77
checked their feet everyday than blacks 86 No difference was found between blacks and whites in daily blood glucose check

Map 1
The prevalence of diabetes appears to be disproportionately high in certain parts of the state Counties in the Southeastern part of the state along the Mississippi delta, shaded blue have the highest estimated diabetes prevalence
19
Map 2
Mortality rates for diabetes are higher in some counties than in others Counties shaded red are those with the highest age-adjusted mortality rates for diabetes
20
Map 3
Diabetes can damage both the nerves and the blood vessels to the feet, leading to numbness, burning sensation, poor circulation and possibly lower extremity amputation Counties shaded blue have higher hospital discharge rates for lower extremity amputations per 1000 people with diabetes
21
Map 4
Diabetes causes heart disease, especially in people with high blood pressure and high cholesterol Heart disease is the leading cause of death among people with diabetes Counties shaded blue have higher hospital discharge rates for heart disease per 1000 people with diabetes
22
Map 5
Poorly controlled diabetes can
result in diabetic retinopathy, and subsequent blindness Counties shaded blue have higher hospital discharge rates for diabetic retinopathy
23
Map 6
The disproportionate burden of diabetic retinopathy in some counties may be associated in part with the differential distribution of the eye care providers Eye care providers tend to be clustered in counties within the central and northwest regions of the state and to be less common, in the remainder of the state
24
Map 7
More than half of the counties do not have an American Diabetes Association ADA recognized diabetes self-management education program Arkansas Diabetes Prevention and Control Program along with its advisory council members are working together to establish ADA-recognized programs in all Arkansas counties
25
Map 8
The Arkansas Diabetes Prevention and Control Program formed the Arkansas Diabetes Advisory Council, along with its partners, to work toward reducing the diabetes burden in Arkansas Although most of the Diabetes Advisory Council members are located centrally in Pulaski County, it has members representing each of the public health regions within the state
