Highlights
In Georgia,
More than 100,000 (10%) children ages 0-10 have asthma. Approximately 56,000 (15%) middle school students have asthma. Approximately 70,000 (16%) high school students have asthma Approximately 480,000 (7%) adults have asthma. There are more than 47,000 emergency room (ER) visits per year with asthma as the
primary diagnosis, and ER charges are approximately $35 million. There are more than 11,000 hospitalizations per year with asthma as the primary
diagnosis, and hospital charges total more than $107 million. Approximately 117 persons die every year from asthma. Blacks are more likely than Whites and women are more likely than men to visit the ER,
be hospitalized or die because of asthma. Despite the fact that cigarette smoking may trigger asthma attacks, approximately 4,500
(8%) middle school students 14,000 (20%) high school students, and one in four (25%) adults with asthma smoke cigarettes. More than 30% of children ages 0-10, two-thirds of middle school students and threefourths of high school students are exposed to secondhand smoke regardless of their asthma status. Appropriate disease management can reduce the burden of asthma, including avoidance of triggers, proper treatment regime, following an asthma management plan created by you and your doctor, and knowing when to seek medical help.

Introduction
Asthma is a chronic inflammatory disorder of the lungs and airways that can include recurrent episodes of wheezing, coughing, shortness of breath, and chest pain or tightness. The cause or causes of asthma are not well understood and likely differ among individuals. Heredity, behaviors such as smoking and environmental exposures, and viral infections all play a role. Once a person has asthma a variety of things can trigger an attack such as allergens (e.g. pollen, dust mites, animal dander etc.), infections, exercise, changes in the weather, and exposure to airway irritants (e.g. tobacco smoke, secondhand smoke, industrial chemicals, etc.) Being obese may also be a risk factor for asthma attacks. Asthma attacks differ in severity for each individual and can be life-threatening. With appropriate clinical management including a written management plan, comprehensive pharmacologic therapy, and avoidance of allergens and other triggers asthma can be controlled, people with asthma in Georgia can lead normal lives.
According to a 2005 report from the National Center for Health Statistics, an estimated 33 million Americans have been diagnosed with asthma at some point in their life and nearly 22 million currently have asthma. 1 In 2004, asthma was responsible for 2 million emergency room (ER) visits, 500,000 hospitalizations, and nearly 5,000 deaths nationwide. 1, 2 Georgia accounts for approximately 47,000 ER visits, 11,000 hospitalizations, and 117 deaths.2, 3 The economic burden of asthma annually (direct and indirect) totaled more than $16 billion nationwide.4 Asthma affects people of all ages, sexes, races, and ethnic groups, but certain subpopulations are disproportionately affected. Blacks and females are more likely to visit the ER, be hospitalized, and die from asthma than Whites and males. 5, 6 Children are also disproportionately affected. This disparity is seen mostly in health care utilization, with ER visit rates and hospitalization rates for children 2 to 3 times higher than for adults. 5, 6
In 2000, the Georgia Department of Human Resource (DHR) and the American Lung Association (ALA) of Georgia jointly produced the first Georgia asthma report, which provided insight into the problem of asthma. Findings highlighted the need for a statewide systematic approach to address the problem of asthma in Georgia. 7 In 2001, the Centers for Disease Control and Prevention (CDC) awarded a grant to DHR to create and implement a statewide plan to address asthma in Georgia. Surveillance was considered a key component to guide the program in its efforts, and the 2003 Burden of Asthma in Georgia report was developed. 8 This report focused on prevalence and risk factors for middle and high school students and adults, morbidity, and mortality. The 2003 report further confirmed that asthma was a major public health problem in Georgia.
The 2007 Georgia Asthma Surveillance Report presents data on asthma prevalence and risk factors for asthma, work-related asthma prevalence, healthcare utilization, deaths, asthma severity, and management practices for all age groups. This report is the third and most comprehensive report available to describe the burden of asthma in Georgia. The purpose of this report is to increase awareness of the burden of asthma on Georgia and to guide public health programs, policy makers, and healthcare providers in the planning, implementation, and evaluation of interventions and programs to reduce the burden of asthma in Georgia.

Risk Factors for Asthma Attacks among Children Ages 0-10
Avoiding tobacco smoke is one way to reduce the frequency of asthma attacks. Tobacco smoke is known to be a trigger for many people with asthma. More than a third (36%) of children with asthma live in a household where at least one parent smokes inside and outside of the home; a significantly lower percent of children without asthma (29%) have this exposure (Figure 5).

In middle school, the prevalence of students who are obese (BMI-for-age 95th percentile) is higher among students with asthma (14%) than among students without asthma (11%). There are no significant differences in the prevalence of obesity among high school students with or without asthma (Figure 11). Although the nature of the relationship between asthma and body weight requires more research, some evidence suggests that people with asthma who are obese experience more symptoms than people with asthma who are not obese. 9-11 Therefore, people with asthma have yet another reason to maintain proper body weight.

Prevalence of Asthma among Adults
Approximately 480,000 (7%) adults in Georgia have asthma. The prevalence of asthma among females (9%) is significantly higher than among males (5%) (Figure 12). The prevalence among Blacks (8%) is similar to Whites (7%) (Figure 13). The prevalence of asthma by age group in adults ranges from 6% to 11% (Figure 14).
The prevalence of asthma is significantly higher in adults with annual household incomes less than $15,000 than in adults with household incomes more than $15,000 (Figure 15). Reasons for these differences are unknown but may be related to environmental exposures more common in low socioeconomic populations.
Prevalence of Asthma among Adults by Public Health District
Current asthma prevalence among adult Georgians in the 18 Public Health Districts ranges from 5% to 9% in 2004-2005 (Appendix I, Table 1). There are no significant differences among the Public Health Districts when compared to each other or to the state.

Risk Factors and Preventive Behaviors for Asthma Attacks among Adults There are many conditions and risk factors that can affect adults with asthma. Despite the fact that smoking may trigger asthma attacks, 21% of adults who currently have asthma report cigarette smoking (Figure 16).
Thirty-six percent of adults with asthma are currently obese (Figure 17). This is a significantly higher prevalence than that for people without asthma (26%).
Influenza is associated with substantial adverse effects especially among people who have asthma, including time lost from work or school, costly ER visits and hospitalization.12, 13 Vaccination reduces morbidity in patients with asthma and immunization is recommended for all such patients.12, 13 Only one-third (34%) of the adults with asthma in Georgia reported receiving a flu shot in the past year (Figure 18).

Health Status
Asthma has a considerable effect on how adult Georgians perceive their health status. Persons with asthma (35%) are more likely to report fair or poor health than those who do not have asthma (15%). Adults with asthma (21%) are also more likely to report mental distress than adults without asthma (10%) (Figure 19).

Work-related asthma is the most prevalent occupational respiratory lung disorder in the United States.14,15 It is estimated that 15% of asthma cases in the United States are due to exposure to allergens or irritants in the workplace.14, 15 Not much data is available in Georgia on work-related asthma because it is not a reportable condition, but according to the Georgia Behavioral Risk Factor Surveillance System (BRFSS), 16% of adults with current asthma stated that their doctor told them their asthma was workrelated or they told their doctor their asthma was work-related (Figure 21). Work-related asthma is a key target group because adults spend the majority of their day at work. Interventions should be developed to improve ventilation or elimination of triggers within the workplace that can increase the frequency and severity of asthma exacerbations or attacks.

Asthma Emergency Room (ER) Visits in Georgia
There were approximately 47,000 ER visits in 2004 in Georgia with asthma as the primary diagnosis. The overall rate of ER visits due to asthma was 510 per 100,000 population. Asthma ER charges were approximately $35 million. There are fewer ER visits during the summer than in any other season of the year (Figure 22).

Females are 1.2 times more likely to visit the ER than males (516 vs. 417 per 100,000 population). Black females have the highest ER visit rate (955 per 100,000 population) among the four major race-sex groups in Georgia (Figure 23). Black females are 3 times more likely to visit the ER than White females. Black males are 4 times more likely to visit the ER than White males (Figure 23).

Asthma Mortality in Georgia
Deaths from Asthma in Georgia
On average, from 2000 to 2004 there were 117 asthma deaths per year (1.6 per 100,000). Age-adjusted asthma death rates in the United States and Georgia increased during the 1980's and early 1990's (Figure 30). In 1999, the classification system for cause of death coding changed from ICD-9 to ICD-10, making it difficult to interpret recent trends in asthma mortality, but the rate appears to be falling.

Asthma deaths affect all races and sexes but death rates disproportionately affect minority populations in the U.S. and Georgia. In Georgia, Blacks are more than twice as likely to die from asthma than Whites (2.9 per 100,000 vs. 1.1 per 100,000 population). Women are 1.6 times more likely to die from asthma than men (1.9 per 100,000 vs. 1.2 per 100,000 population). Death rates by race and sex ranged from 0.8 per 100,000 populations for White males to 3.3 per 100,000 population for Black females (Figure 31).

Asthma Severity and Impact in Georgia
Asthma is a life threatening disease that can have a negative effect on the lives of children and adults with asthma, as well as the family members who care for them. When asthma is not in control a person's daily life can be disrupted.
Children According to the second Statewide Georgia Childhood Asthma Survey, 60% of children with asthma have had an asthma attack in the past 12 months. Among children 5 to 17 in Georgia, about 75,000 (48%) children reportedly missed 470,000 days of school due to their asthma. In addition, about 48,000 (23%) of children with asthma reportedly had "moderate" to "a lot" of activity limitation when compared to their friends over a lifetime period. (Figure 33). When a person's asthma is under control daily activity should not be limited.
Adults
The National, Heart, Lung and Blood Institute (NHLBI) guidelines classify asthma into four different categories ranging from mild to severe.16 Among adults with asthma in Georgia, 21% fall into the severe persistent category, signifying their asthma is not in control (Figure 34).

Asthma Management in Georgia
Disease Management
Asthma self-management, the direct involvement of patients and their caregivers in strategies to control their disease, has become an important component of asthma care. Asthma self-management reduces ER visits, hospitalizations, unscheduled office visits, and asthma-related healthcare cost. Asthma management should begin with a proper diagnosis of the disease, identification of triggers that are common to people with asthma as well as knowing your personal triggers, and reducing exposure to these triggers. The NHLBI recommends that individuals with asthma work with their doctor to create an asthma management plan, which can help persons recognize early signs and symptoms of an attack, determine which medicines to take and when to take them, and recognize when to seek medical attention. Asthma cannot be cured, but with proper pharmacologic therapy, avoidance of triggers, and management, it can be controlled.
Adults
Routine visits recommended by the NHLBI guidelines should be used to discuss asthma-related problems.16 Patients should develop their management plan and let their doctor know when anything in their management plan is not working, and the doctor should work with them to modify the plan to better suit their needs. Despite these recommendations, in Georgia 42% of adults with asthma have not had a routine checkup for their asthma in the past 12 months (Figure 39).

Among children with asthma, 84% use prescription medicine, including 36% who use prescriptions for both control and quick-relief medicine, 14% who use a prescription only for control medicine, and 34% who use a prescription only for quick relief medicine (Figure 41).
NHLBI guidelines state that use of 2 quick-relief treatments per week or 2 prescriptions per year may indicate need for control medicine to reduce inflammation and prevent exacerbations.16 Among Georgia children with asthma who have a prescription only for quick relief medicine, 17% of all children with asthma use 2 prescriptions per year. The NHLBI Guidelines also recommend that patients receive periodic assessments and be given a written plan by their health care provider.16

In Georgia, 30% of children with asthma do not have regular asthma check-ups and 65% do not have a written plan to help them manage their asthma (Figure 42). There are other asthma management and training areas in which Georgia could use improvement to help prevent frequency and severity of attacks.

Conclusions
Asthma is a major public health issue in Georgia, as it is in the United States. In Georgia, 10% of children ages 0-10, 15% of middle school students, 16% of high school students, and 7% of adults report currently having asthma. This report shows that asthma affects all age, race, and sex groups, but certain groups are disproportionately affected. Blacks and women are more likely to visit the ER, be hospitalized, and die from asthma than Whites and men. Asthma hospitalizations are highest among the older and younger age groups. Death rates are 25 times higher for the elderly (65 years of age and older) than for the younger age groups (0 to 4 years and 5 to 24 years).
Findings presented in this report suggest at least five ways by which the burden of asthma in Georgia can be reduced:
1) Reduce cigarette smoking and exposure to environmental tobacco smoke 2) Improve access to quality healthcare 3) Increase receipt of annual flu vaccination 4) Increase physical activity and improve diet to reduce obesity 5) Increase knowledge and adherence to proper treatment and management practices
Reduce smoking and exposure to environmental tobacco smoke (ETS)
Despite the fact that cigarette smoking may trigger asthma attacks, youth and adults with asthma continue to smoke: 25% of adults with asthma, 20% of high school students with asthma, and 8% of middle school students with asthma currently smoke. Approximately two-thirds middle school students and three-fourths of high school students with asthma are exposed to environmental tobacco smoke. Smoking and exposure to environmental tobacco smoke (ETS) have been shown to increase the frequency and severity of asthma attacks. Stopping smoking and limiting exposure to ETS can help reduce the frequency and severity of asthma attacks. Policies that prohibit or restrict smoking are important factors in this effort.
Improve access to quality healthcare
A substantial number of adults with asthma (27%) were unable to see a doctor because of cost. Lack of access to adequate healthcare can make it difficult for individuals to keep their asthma under control. Asthma is a disease that can be controlled with proper treatment and management. Therefore, programs to help people receive proper treatment and self-management education need to be made available.
Increase receipt annual flu shot
Respiratory infections are a common trigger of asthma attacks. Annual influenza vaccinations for people with asthma will reduce the incidence of asthma attacks. However, only about one-third of adults with asthma have received their annual flu shot.
22 | 2007 Georgia Asthma Surveillance Report
Increase physical activity and improve diet A higher percent of high school students with asthma are obese (14%) compared to those without asthma (11%). Thirty-six percent of adults with asthma are currently obese. The relationship between asthma and obesity is not well understood, but obese individuals tend to experience more symptoms than people of normal weight. Asthma is a disease that should not limit an individual's normal activities. Programs to help individuals with asthma participate in physical activities and to eat a healthy diet can help reduce asthma symptoms.
Increase knowledge of proper treatment and management practices The NHLBI guidelines recommend that patients with asthma receive periodic assessments and be given a written plan by their health care provider. In Georgia, 30% of children with asthma do not have regular asthma checkups and 42% of adults with asthma do not have regular checkups for their asthma. Two-thirds of children with asthma do not have a written management plan to help manage their asthma. Children who have a prescription for quick relief medications only and are refilling the prescription more than two times a year need to be evaluated for control medication. People with asthma in Georgia can live normal, active, healthy lives by knowing the common asthma triggers and reducing their exposure to them, especially triggers specific to their asthma. Individuals with asthma need to work with their doctor to create an asthma management plan that will tell them what brings on their asthma symptoms, how to avoid triggers and reduce exposure, what medicines to take and when to take them, and when to seek medical help. People with asthma must work with their doctor to understand instructions for their medications and take them as scheduled. If the medications are taken as scheduled and are not working, they should let their physician know and discuss revisions that may be needed. Asthma education, proper treatment and management, policy changes, and modification of risk factors will help reduce frequency and severity of asthma attacks in individuals with asthma and possibly delay or prevent the development of asthma in individuals without asthma. These actions will ultimately reduce the burden of asthma in Georgia and improve the quality of life of Georgians with asthma, their families, and society at large.

Appendix II: Data Sources for Asthma
The Georgia Childhood Asthma Survey
The Georgia Childhood Asthma Survey was a random digit-dial telephone survey of households in Georgia. A parent or caregiver in households with at least one child aged less than 18 years reported on all children residing in the home. The survey was conducted from October 2002 through February 2003. The data were collected by the University of Georgia Survey Research Center in Athens, GA. Asthma was defined according to the standard case definition for probable asthma: the child was ever diagnosed with asthma, and 1) has been told by a physician that the child still has asthma, 2) takes prescription medicine for asthma, or 3) has had an asthma attack in past twelve months. Household and caretaker data were weighted according to the number of telephone lines in the household. Child data were weighted according to the number of telephone lines in the household and to the 2000 Georgia Census population.
The Georgia Youth Tobacco Survey
The Georgia Youth Tobacco Survey is a self-administered pencil and paper survey given to Georgia's middle and high school students. The main focus of this survey is tobacco use. This survey was last conducted in 2005. Two questions about asthma were added 1) "Has a doctor or nurse ever told you that you have asthma?" 2) "During the past 12 months have you had an episode or an asthma attack?" Other information included height and weight to calculate BMI. For both middle school and high school the data weight variable was calculated for each record to reflect the likelihood of sampling each student and to reduce bias by compensating for differing patterns of non-response. SUDAAN was used to compute the 95% confidence intervals, which were used to determine the differences between subgroups. Differences between prevalence estimates were considered statistically significant if the 95% confidence intervals did not overlap. This survey does not include students who do not attend public middle school and high school, were home schooled, or those who do not attend school at all.
The Behavioral Risk Factor Surveillance System (BRFSS)
The Behavioral Risk Factor Surveillance System (BRFSS) is stratified random digit dial telephone interview survey conducted in cooperation with the Centers for Disease Control and Prevention (CDC). Georgia residents18 years and older are interviewed annually about their health conditions, behaviors, and the use of preventive services. Asthma was one of the topics included in the 2002-2006 core section. The questions were 1) Have you ever been told by a doctor, nurse, or other health professional that you had asthma?" 2) Do you still have asthma?" In addition, the adult asthma history module, which consists of nine questions related to asthma history, healthcare utilization, and asthma medication use were included in 2003-2005 modules. In 2005 the state of Georgia added two questions concerning work-related asthma. 1) "Were you ever told by a doctor or other medical person that your asthma was related to any job you ever had?" 2) "Did you ever tell a doctor or other medical person that your asthma was related to any job you ever had?" Prevalences for 2004-2005 combined were estimated using SAS and SUDAAN, which take into account the stratified sample design of the BRFSS. People without a telephone are not included in the survey.
2007 Georgia Asthma Surveillance Report | 31
Georgia Emergency Room (ER) Visit Data Emergency room (ER) visit data in this report are based on ER visit data by Georgia residents who were seen in the ER in 2004 with asthma as the primary diagnosis. The ICD-9 codes used to select hospitalizations were 493.0-493.9. ER visit data included only information reported by non-federal acute care hospitals in Georgia. Rates were age-adjusted to the 2000 US standard population via the direct method. ER visit charges may differ from costs. Charges are based upon the hospital's full-established rates. The amount a hospital is reimbursed is usually less than what is charged.
Georgia Hospital Inpatient Discharge Data Hospitalization data in the report are based on hospital discharge data for Georgia residents who were hospitalized in 2004 with asthma as the primary diagnosis. The ICD-9 codes used to select hospitalizations were 493.0-493.9. Hospitalization data included only information reported by non-federal acute care hospitals in Georgia. Rates were age-adjusted to the 2000 US standard population via the direct method. Hospitalization charges may differ from costs. Charges are based upon the hospital's full-established rates. The amount a hospital is reimbursed is usually less than what is charged. Georgia Vital Statistics Death Data Mortality data are based on deaths of Georgia residents whose underlying cause of death was asthma. Deaths from 1999-2004 with ICD-10 codes J45-J46 were selected. Death rates were age-adjusted to the 2000 US standard population via the direct method. Recent trends suggest that mortality rates are decreasing; one factor may be the change from ICD-9 to ICD-10 coding of deaths in 1999. Death and hospitalization rates are expressed per 100,000 population throughout the report.
