2. BACKGROUD Inhaled anti-inflammatory medicines are suggested for disease control in asthma patients (NAEPP). Increasing use of short-acting bronchodilators indicates inadequate control of the disease (NAEPP).

3. PURPOSE To examine and evaluate the effectiveness of a self- regulation telephone counseling intervention for women with asthma on medication use in a randomized clinical trail.

4. METHODS Recruitment Women 18 years and older Physician diagnosis Attending University of Michigan Asthma & Airways Clinic and University of Michigan Health System

5. Data Collection Telephone interview Demographics Asthma symptoms Health care utilization Gender-related management Peak flow meter use

6. Study Sample Baseline 808 Follow up I* 608 Follow up II**580 One year subsequent to baseline data collection One year subsequent to follow up I data collection

7. Demographics: Age

8. Demographics: Education

9. Demographics: Income

10. Demographics: Race/Ethnicity

11. Intervention  Subsequent to baseline data collection, women were randomly assigned to either the control or the intervention group.  Women in the intervention group received the self-regulation telephone counseling intervention: Women Breathe Free.

12. Data Analyses To examine: 1. Relationships between demographics vs. Medication use at baseline: Frequencies with Odds Ratio 2. Program effects on medication use: Generalized Estimating Equations (GEE) with logit link using entire sample (intent-to-treat)

13. FINDINGS Asthma Severity Classified by NAEPP criteria, Guidelines and Diagnosis and Treatment of Asthma, 1997 Percent of Women Mild intermittent52% Mild persistent15% Moderate persistent20% Severe persistent13%

14. Demographics and Lower Use of Inhaled Anti-Inflammatory Medications ORP-value Age <50 years13.8<.002 Lower education3.9<.05 Minority7.9<.005

15. Program Effects on Medication Use 1.Inhaled non-steroid use increased more in the 12 month follow up perceived in the treatment group (p=.09).

16. 2. Significantly more reduction to use short-acting bronchodilators at 24 month follow up in treatment group (p=.05)

17. CONCLUSIONS A. Women of lower education and younger age used less inhaled anti inflammatory medicine B. The intervention improved medicine use over the evaluation period
