              Viewing and Printing Tables and Maps
              The view option for your browser should be set to the smallest available text size to ensure that columns of numbers are properly formatted and that part of the page is not lost when printing.
              Be sure your screen colors are set to True Color (24 bit) or greater so that the colors and shadings on the maps are clearly discernable. Maps are also provided in black and white (B/W) if a color printer is not available. Maps should be printed in landscape orientation.
              Tables are provided in both HTML and PDF format. The PDF files will load more quickly, but cannot be used with ADA assisted technology. Tables printed in portrait orientation using Adobe Acrobat may produce more pleasing results than printing the HTML-formatted tables.
              BRFSS Questionnaire
              In 2010, the BRFSS survey was conducted in all 50 states, the District of Columbia and in three US territories (Guam, Puerto Rico and the Virgin Islands).
              In each area where interviews are conducted, respondents are randomly selected from noninstitutionalized civilian adults (18 years of age or older) living in households with a telephone BRFSS User’s Guide [PDF – 986 KB] . Asthma prevalence data are produced from the responses to two asthma questions on the year 2010 BRFSS Core Questionnaire.
              Lifetime asthma: Question number 9.01
              “Have you ever been told by a doctor, nurse, or other health professional that you had asthma?” (variable name: ASTHMA2)
              The calculated variable _LTASTHMA (based on question 9.1) from the public use file was used when creating the tables.
              Current asthma: Question number 9.2
              If the response to 9.1 was Yes, then question 9.2 was asked: “Do you still have asthma?” (variable name: ASTHNOW)
              The calculated variable _CASTHMA (based on questions 9.01 and 9.02) from the public use file was used when creating the tables.
              Subgroup tables are based on data from the following questions:

                Data Analysis
                Data Used:
                The BRFSS 2010 Survey Data file was used to calculate estimates for all states.
                Software:
                Prevalence and standard error estimates were calculated using SUDAAN Release 10.0.1 (Research Triangle Institute, P.O. Box 12194, Research Triangle Park, NC 27709).
                Data Management:
                Only respondents with values of the variables as described in the table above are included in each prevalence table. Responses of “don’t know/not sure,” “refused,” or missing values were excluded.
                Ratio of Adult Self-Reported Current to Lifetime Asthma by State:
                The ratio is a survey-based estimate of prevalence of asthma based on those surveyed who responded “Yes” to question 9.1, “Did a doctor ever tell you that you had asthma?” It is not a rate ratio.
                Confidence Intervals:
                The 95% Confidence Intervals were calculated using the following formulae:
                Lower 95% Confidence Interval = % prevalence – t (sep)
                Upper 95% Confidence Interval = % prevalence + t (sep)
                Where sep is the standard error of the prevalence percent and t equals the z distribution value of 1.96 for state level prevalence in Table 1. For other tables with smaller sample sizes due to the use of demographic subcategories, the exact value from the t distribution appropriate to the sample size for the percent prevalence was used instead of the approximate z-value of 1.96. Because of the use of the more exact t-value, 95% Confidence Intervals in the tables may differ slightly from those presented in other representations of these data.
                Table Conventions:
                The “US Total” line of each table excludes Puerto Rico, Guam and the Virgin Islands. “US Total,” therefore, designates an estimate for the 50 states and the District of Columbia combined.
                In the tables, states are listed in Federal Information Processing Standard (FIPS) code order.
                Washington, D.C., is omitted from the maps. Its area is so small that the map colors and patterns were not discernible.
                Ranges in all maps (both overall and for subgroups) are based on quintiles of the overall prevalence estimates from year 2000 data. These same ranges will be used in future years to facilitate year-to-year comparison of the maps.
                Chart:
                The chart presents the state and territory prevalence percents from Table 1 sorted from high to low. Confidence intervals are also represented graphically for each prevalence value. Overlapping confidence intervals for two states is a rough indication that state prevalence values are not significantly different from one another.

                Small Sample Size
                When sample sizes in cells are less than 50, as they are in some of the subgroup tables, the standard error may be large relative to the prevalence value, leading to a wide 95% confidence interval. Caution should be used in interpreting such “imprecise” estimates of prevalence.
                Also, when one or more of the following situations occurred, the indicated solutions were applied:
                Possible Situations and the Solutions
                  Situation                                                                                                                                       Solution                                                                                                                                                             
                  1. The normal distribution approximation to the binomial distribution did not apply.                                                            1. Values for the standard error and the 95% confidence interval were not provided.                                                                                  
                  2. If the normal distribution approximation does apply, it is appropriate to use values of the t-distribution to compute confidence intervals.  2. Two-sided 95% confidence interval values from the t-distribution with (n-1) degrees of freedom (where n is the number of observations for the subgroup) were used.
                  3. The lower limit of the 95% confidence interval was negative.                                                                                 3. The lower limit was set to zero.
