  1. Diabetes Data presentationDecember 20, 2012

  2. Agenda • Overview • New BRFSS data weighing • Pre-diabetes • Prevalence • Incidence • Eyes and kidneys • Diabetes and smoking • Diabetes Self-Management • Quality of Care • Conclusions

  3. BRFSS Data Weighing Changes Raking (new method) versus Post-stratification (old method) Post-stratification – • landline telephones only • survey data weighted (or normalized to census data) by: • sex and age groups by region

  4. BRFSS Data Weighing Changes Raking (new method) versus Post-stratification (old method) Raking – • landline telephones and cell phones (starting in 2011) • survey data weighted (or normalized to census data) by: • Age group by sex • Race • Education level • Marital Status • Home ownership or renter • Sex by race • Age group by race • Telephone source/type (respondent has cell-only, landline-only, or both cell and landline) • Region • Region by age group • Region by sex • Ethnicity

  5. Why capture cell phones and better adjust the data? • In recent years, the old method under-represents important segments of the population

  6. Pre-diabetes

  7. Adult Alaskans withpre-diabetes by race and AK BRFSS region, 2009-2011- Post Strat

  8. Adult Alaskans withpre-diabetes by race and AK BRFSS region, 2009-2011- Raked

  9. Adult Alaskans withpre-diabetes by race and AK BRFSS region, 2009-2011- Raked

  16. Diabetes incidence

  17. Age at diabetes diagnosis by race, 2009-2011

  19. Eyes and Kidneys Vision loss likely related to diabetes increased in US adults from1.4 percent in 1999 through 2002 to 1.7 percent in 2005 through 2008, an increase of 21 percent within less than a decade in the U.S.. Dr. David Friedman from the Wilmer Eye Institute of Johns Hopkins University School of Medicine in Baltimore Fang K, Vitale S, Chou C, Cotch MF, Saaddine J, Friedman D.

  24. Health care provider advised stop smoking within previous year by diabetes diagnosis group, 2009-2011

  25. Diabetes Self-Management

  26. 2000-2011 trend in percentages of Alaskans with diabetes with diabetes education (had ever taken a diabetes self-management class)

  28. Quality of Care

  29. Trends in percentages of Alaskans with diabetes that had received 0, 1, 2 or 3 quality of care activities (dilated eye exam, foot exam and/or at least 2 A1c tests) in the previous year, 2004-2011

  30. Trends in percentages of Alaskans with diabetes that had received 0, 1, 2 or 3 quality of care activities (dilated eye exam, foot exam and/or at least 2 A1c tests) in the previous year, 2004-2011

  31. Trends in percentages of Alaskans with diabetes that had received 0, 1, 2 or 3 quality of care activities (dilated eye exam, foot exam and/or at least 2 A1c tests) in the previous year, 2004-2011

  32. Percentages of Alaskans with diabetes that had received 0, 1, 2 or 3 quality of care activities (dilated eye exam, foot exam and/or at least 2 A1c tests) in the previous year by race /insurance status, 2009-2011 3 Health Insurance 0 1 2

  33. Conclusions

  34. Conclusions • The new data weighting method, or raking, does change • Percentages – but doesn’t change or detract from major findings • Alaska Natives have higher rates of prediabetes than whites • Southeast Alaska has higher rates of prediabetes than Fairbanks • Obese Alaskans have higher rates of prediabetes than overweight and healthy weight Alaskans • Diabetes prevalence essentially doubled over last 20 years • Age of diabetes diagnoses influenced by race and age, but not obesity • Alaskans with diabetes have more kidney problems and cataracts • Greater percentage of Alaskans with diabetes are former smokers versus pre-diabetes and no diabetes groups • Health insurance seems to be a factor in whether or not diabetes receive recommended quality of care activities.
