  1. Behavioral Risk Factor Surveillance System (BRFSS) Contributors: Wayne A. Honey, MPH Jennifer E. Daniel, MPH Annie Hickman, BS Survey Unit, Injury & Behavioral Epidemiology Bureau Epidemiology & Response Division, NM Department of Health December 8, 2004

  2. BRFSS - Objectives • Determine priority health issues & populations at highest risk for illness, disability, and death. • Support development of strategic plans • Target prevention programs • Educate the public, the health community, and policy makers about disease prevention.

  3. BRFSS - Objectives • Support community policies that promote health and prevent disease. • Monitor the effectiveness of interventions and progress in meeting prevention goals (limited).

  4. BRFSS – Applications (Examples on following slides) • Estimate: Prevalence & Distribution of Selected Diseases/Conditions • Estimate: Prevalence & Distribution of Risk Behaviors & Protective Factors • Comparison to HP2000 & HP2010 • Monitor Trends

  5. Binge Drinking 2003

  6. 2003 NM BRFSS & Healthy People 2010 Obj’s

  7. Monitor Trends

  8. Breast Cancer ScreeningNo Significant Difference (Other than 1991 & 1997)All Female Respondents Age 40+, excluding DK/NS, Refused, or missing.

  9. BRFSS – Applications (Examples on following slides) • Describe Associations Between Disease/Conditions & Risk Factors • Estimate: Prevalence of Health Care Coverage • Comparisons: State-to-State, State to Nation; sub-state areas • Estimate: Utilization of Preventive Screening

  10. Associations Prevalence of Chronic Health Conditions*, by disability status 100 No disability Disability not requiring assistance 80 Disability requiring assistance 60 Percent of group with condition 40 20 0 Arthritis Diabetes Hypertension Cardio- Osteoporosis (2000) (1998-00) (1999) vascular (1999) disease (1998,99) * Rates are age-adjusted by the direct method to the weighted age distribution of the NM BRFSS survey for the designated year or years.

  11. Comparisons: State-to-State; State-to-Region; State-to-Nation Percentage of New Mexicans Without Health Care Coverage

  12. Percentage of Women Age 40 and Older Who HaveNever Had a Mammogram, by Education. New Mexico, 2000.

  13. BRFSS - Methodology • Telephone Survey Methods • On going Survey of Adults • Random Selection of Household • Random Selection of One Adult (>= 18 Yrs.) Per Household • Computer-Aided Telephone Interviewing (CATI) System

  14. NM BRFSS Sample Geographic Stratification* Stratified since 2001 2004 Sample Size = 6,430 Sample Per Stratum = 1,286 DSS Design Replicated in each stratum. 2004: 6th Stratum over-sampling Native Americans *County assignment to strata will change in 2006 to match new Public Health Districts.

  15. BRFSS - Strengths • State & Sub-state Estimates • State Control • Timeliness • Reasonable Reliability & Validity (with caveats) • Efficiency (Cost) • Effective Monitoring of Data Collection

  16. BRFSS - Weaknesses • Validity (Self-report) • Reliability (Select Variables or small sample size) • Refusal Rates higher than Face-to-Face, and Increasing • Exclusion of non-telephone HH • Exclusion of Cell Phones
