This interdisciplinary multi-level study moves the research in asthma health disparities from descriptive studies of individual constructs and contexts to testing an integrated, multi-factorial model among Latino families and children with asthma. The investigators seek to gain a more thorough understanding of the interaction of individual characteristics, cultural and experiential factors, social-environmental context, and healthcare system factors on parents' illness representations, use of CAM and controller medications, and children's asthma health outcomes.

This will be a one-year longitudinal, multi-site (Phoenix, AZ and Bronx, NY) study among samples of Mexican (N=300) and Puerto Rican (N=300) parents and children aged 5-12 who have asthma.

Aim #1: Are there differences in illness representations between Mexican and Puerto Rican parents due to social and contextual factors (i.e., acculturation, education, parental age, poverty, child's illness duration, household members with asthma, and parent-healthcare provider relationship)?

Aim #2: Are disparities in asthma control between Mexican and Puerto Rican children due to differences in parents' treatment decisions (CAM and controller medication use) and changes in illness representations over a one year period after controlling for the effects of acculturation, social and contextual factors, environmental triggers, and advice received from others?

Sampling Method:   Non-Probability Sample
Study Population
To ensure diverse representation of Latino families and healthcare settings, the sample will be recruited from two school-based health clinics and one clinical practice site in Phoenix, AZ, and two inner-city hospital asthma clinics in the Bronx, NY. Approximately 300 families will be recruited and enrolled from the asthma/allergy and general pediatric clinics and ER at Jacobi Medical Center and North Central Bronx Hospital (N= 150), Phoenix Children's Hospital Breathmobile (N= 75), and the two school-based health clinics in Phoenix (N= 75).

Inclusion Criteria:

  • child must be between 5 and 12 years of age,
  • have a diagnosis of asthma as obtained from the child's medical record,
  • the family is Latino (English or Spanish speaking) as self-identified by the primary caregiver,
  • the child has no other significant pulmonary conditions (e.g., cystic fibrosis),
  • the participating parent has primary or at least equal responsibility for the day-to-day management of the child's asthma, and
  • no cognitive learning disability that could interfere with the parent's or child's (as determined by parents' report) ability to comprehend the interview questions.

Exclusion Criteria:

  • children not meeting the above inclusion criteria
  • parents who do not have primary or equal responsibility for the child's asthma mangement
