The purpose of the study is to conduct a cross-sectional study to examine asthma prevalence and morbidity in a predominately minority, low-income population in rural Arkansas.


Study Type: Observational
Study Design: Observational Model: Ecologic or Community
Time Perspective: Cross-Sectional
Official Title: Asthma in the Delta Region of Arkansas (ADRA): Prevalence and Morbidity

Further study details as provided by Arkansas Children's Hospital Research Institute:

Primary Outcome Measures:
  • The findings suggest that asthma diagnosis and active symptoms are prevalent among this predominately minority and low-income rural population in the Arkansas region of the Mississippi Delta. [ Time Frame: One year ]

Secondary Outcome Measures:
  • High rates of inadequately controlled asthma are evidenced by activity limitation, medication use and increased healthcare utilization. [ Time Frame: One year ]

Enrollment: 964
Study Start Date: August 2005
Study Completion Date: August 2008
Primary Completion Date: May 2006 (Final data collection date for primary outcome measure)
Children at risk for asthma were identified using a cross-sectional asthma screening survey.

Detailed Description:
Asthma is the leading chronic disease of childhood in the United States and an important public health concern in Arkansas. Arkansas, a predominately rural state, has one of the leading mortality rates in the nation for African Americans. The specific aims of the study will examine asthma prevalence in children age 4-17 years old in public schools in Eudora and Marvell Arkansas. The study will also examine asthma morbidity among identified asthmatics by characterizing activity limitation, days missed from school, daytime and nocturnal symptoms, healthcare utilization and medication use. The specific aims of the current study will provide novel data on an understudied population of asthmatics and will test our working hypotheses that pediatric asthma prevalence in the Delta region of Arkansas is higher than national estimates; and asthma diagnosis is related to significant morbidity among rural asthmatics.

Ages Eligible for Study:   4 Years to 17 Years   (Child)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes
Sampling Method:   Non-Probability Sample
Study Population
During the 2005-2006 school year, primary caregivers of all students aged 4-17 years attending public school in Eudora and Marvell Arkansas were asked to complete an asthma screening survey regarding their child. The schools are located in two non-contiguous counties in the Delta region of Arkansas and are in rural low-income areas of the state where more than one-third of families with children 5-17 years old meet the 2000 poverty line (Census bureau).

Inclusion Criteria:

  • Children aged 4-17 years, enrolled in the public schools in Eudora and Marvell Arkansas.

Exclusion Criteria:

  • Children aged 18 or older enrolled in the public schools in Eudora and Marvell Arkansas were excluded.
