DIABETES DATA PRESENTATION DECEMBER 20, 2012

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

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 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 BRFSS Data Weighing Changes

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

Pre-diabetes

Adult Alaskans with pre-diabetes by race and AK BRFSS region, Post Strat

Adult Alaskans with pre-diabetes by race and AK BRFSS region, Raked

Percent of Adult Alaskans with Pre-diabetes by Leisure-time exercise and BMI levels

Diabetes Prevalence, Old / New Data Method

Diabetes incidence

Age at diabetes diagnosis by race,

Age at diabetes diagnosis by BMI category,

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..

Percent of Alaskans with and without Diabetes with Kidney or Eyesight Problems 2011

Diabetes and tobacco use

Percentages of adult Alaskans with diagnosed diabetes, pre-diabetes or no diabetes by smoking status,

Health care provider advised stop smoking within previous year by diabetes diagnosis group,

Diabetes Self-Management

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

trend in percentages of Alaskans with diabetes with diabetes education (had ever taken a diabetes self-management class) Post Strat v. Raked

Quality of Care

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,

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, Health Insurance 012 3

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.
