NHIS is a survey of the civilian, noninstitutionalized population of the United States.2 Adult respondents were asked whether a health professional had ever told them they had diabetes. Women who responded that they had been told they had diabetes during pregnancy only were not considered to have diabetes. Respondents who answer “yes” to the question, “Do you have any trouble seeing even with glasses or contacts?” were considered to have VI. Respondents who answered “yes” to the question, “During the past 12 months, have you seen or talked to an optometrist, ophthalmologist, or eye doctor (someone who prescribes eyeglasses) about your own health?” were considered to have had contact with an eye-care provider in the past year. Prevalence of self-reported VI in persons with diabetes was estimated by age, sex, race, ethnicity, education level, time since diagnosis of diabetes, current insulin use, contact with an eye-care provider in the past year, and health insurance coverage in the past year. The racial groups (i.e., whites and blacks) included persons of both Hispanic and non-Hispanic ethnicity, and the ethnic group (i.e., Hispanics) included persons of any race. Annual prevalences were calculated using 3-year moving averages to improve the precision and reliability of the estimates, and these averaged annual estimates were age-adjusted on the basis of the 2000 U.S. standard population. Joinpoint regression based on single years of data was used to analyze trends. Joinpoint regression uses permutation tests to identify points (i.e., joinpoints) where linear trends change significantly in direction or magnitude (e.g., zero joinpoints indicates a straight line).* The rate of change for each trend is tested to determine whether it is significantly different from zero, and each trend in the final model is described by an annual percentage change with a 95% confidence interval. Results were considered significant if p<0.05. The NHIS response rate for adult respondents over the entire 14-year period averaged 70.5% but ranged from 80.4% in 1997 to 60.8% in 2010.
