Impact of Air Quality on Asthmatic Patients in the South Senge Ngalame
Concordia University
Epidemiology of Air Quality• Asthma affects 5-10% of the population or an estimated 23.4 million persons, including 7 million
children
• 7.6% of people in the south have asthma
• In the most recent listing of the 10 worst cities for Asthma, included the following southern cities and states, Richmond, VA( 1st), Chattanooga, TN (2nd ), Memphis, TN(3rd ), McAllen, TX(8th), Atlanta, GA(9th), and Knoxville, TN(10th)
• Average annual rate of physician office visits is 56.6 visits per 100 persons with asthma
• The visit rate of the emergency department is 8.7.
• The death rate is 1.5 and 1.6 per 10,000 persons with asthma.

U.S. State InfoAdults with asthma in the US, 2009
Annual U.S. Prevalence Statistics for Chronic Diseases
Biomedical Basis• The air quality can give physiological, long
and short term effects on a person’s body.
• Air pollution is an immediate irritant that can aggravate sensitive areas such as the eyes, throat, nose and lungs
• Household combustion devices, motor vehicles, industrial facilities and forest fires are common sources of air pollution
• Air can be contaminated by a range of very different particles such as dust, pollen, soot, smoke, and liquid droplets
• Ozone (03), Nitrogen dioxide (NO2), Sulfur dioxide (SO2) and particulate matter are common factors in affecting air quality
Formation of Ozone
Environmental Factors • Nearly half (46 percent) of the U.S. population
live in counties that have unhealthful levels of either ozone or particle pollution
• An estimated 1-in-5 cases of asthma in the U.S. is linked to exposures to mold and dampness in homes; this costs the nation an estimated $3.5 billion in annual medical treatment costs.
• Asthma can aggravated by exposure to pollutant "triggers" such as certain components of vehicle exhaust and industrial emissions, tobacco smoke, pollen and allergens from animals and insects
• Urban environments have high levels of outdoor pollution and poor housing conditions, which frequently are associated with increased levels of indoor pollution
Social and Behavioral Factors • For adults, asthma is the fourth leading cause of
work absenteeism and “presenteeism,” resulting in nearly 15 million missed or lost ("less productive") workdays each year (this accounts for nearly $3 billion of the "indirect costs")
• Among children ages 5 to 17, asthma is the leading cause of school absences from a chronic illness
• It accounts for an annual loss of more than 14 million school days per year (approximately 8 days for each student with asthma) and more hospitalizations than any other childhood disease.
• It is estimated that children with asthma spend an nearly 8 million days per year restricted to bed
• The American Lung Association stated being in heavy traffic, or living near a road, may be even more dangerous than being in other places in a community
Biostatistics • The CDC stated that the south has 14,544 people who have asthma
• 10,456 of those people are adults 18 and up
• 4,088 represents children under 18
• In the southern region, 10-50 millions of tons of coal is being burned up by coal fired power plants
• A way to check the air quality to make sure it is safe is the Air Quality index
• The Air Quality Index (AQI) relates daily air pollution concentrations for ozone particle pollution, NO2, CO, and SO2 to health concerns for sensitive groups and for the general public
• Values below 100 are considered satisfactory. Values above 100 are considered unhealthy – first for certain sensitive groups of people, then for everyone as the AQI values increase
Biostatistics pt.2• In the southern region, between the years 2002-2007, the AQI values were considered
unhealthy for 10-20 days
• EPA strengthened the national standards for ground-level ozone, setting an 8-hour standard at 0.075 parts per million (ppm)”.
• The measure of ground level-ozone in the southern region was between 0.060-0.0075 ppm
• In certain areas of Alabama, Georgia, Tennessee, North Carolina, South Carolina, and Virginia, it was between 0.076-0.095 ppm.
Air Quality Index
Policy• The National Institutes of Health states: federal, state, and local health officials can track asthma
rates and the effectiveness of control measures so continuous improvements can be made in prevention efforts, promote influenza and pneumonia vaccination for people with asthma, and promote improvements in indoor air quality for people with asthma through measures such as smoke-free air laws and policies, healthy schools and workplaces, and improvements in outdoor air quality.
• The Clean Air Act, which was last amended in 1990, requires EPA to set National Ambient Air Quality Standards (NAAQS) for wide-spread pollutants from numerous and diverse sources considered harmful to public health and the environment.
• Two types of national air quality standards were established Primary standards set limits to protect public health, including the health of "sensitive"
populations such as asthmatics, children, and the elderly Secondary standards set limits to protect public welfare, including protection against visibility
impairment, damage to animals, crops, vegetation, and buildings
Policy pt.2• Requires periodic review of the science upon which the standards are based and the standards themselves
• The CDC established the National Asthma Control Program (NACP) Helps Americans to learn about asthma and how to manage it The NACP first incorporated interventions into its cooperative agreement structure in 2002 That year the program funded grantees to implement two scientifically-evaluated asthma interventions:
the Asthma and Allergy Foundation of America’s “Asthma Care Training for Kids” and the American Lung Association’s “Open Airways for Schools.”
Surveillance data show that these interventions decrease acute care visits and hospitalizations and increase compliance with asthma care plans.
By 2007, NACP funded all 36 grantees to develop and maintain a broad array of asthma interventions Including programs or campaigns for adult-specific asthma education and prevention, asthma
awareness, outreach, and communication, caregiver, school- and childcare center-based education and prevention, education and prevention targeted to underserved populations, trigger reduction and home visits, healthcare provider education and training, health plan coverage of asthma services, indoor air quality-based education and prevention, senior citizen-specific asthma education and prevention, state systems-based change, and tobacco use reduction.
