Maps of trends in diagnosed diabetes

The maps show the trend in age\ue2\u20ac\u201cadjusted prevalence of diagnosed diabetes among adults aged 18 years or older in the United States from 1994 through 2013. During the period, prevalence of diagnosed diabetes has increased across the states in the United States. In 1994, 25 states had prevalence less than 4.5%, 24 states had prevalence of 4.5%\ue2\u20ac\u201c6.0%, and only 1 state had prevalence greater than 6.0%. In 2013, all states had prevalence greater than 6.0%, 25 of these exceeded 9.0%.Because there were major changes in the survey methods in 2011\ue2\u20ac\u201d the addition of cellular telephone-only households and a new method of weighting the data\ue2\u20ac\u201d caution should be taken when comparing estimates across 2011.The addition of cellular telephone-only households has increased the numbers of certain population groups\ue2\u20ac\u201drespondents who have lower incomes, lower educational levels, or are in younger age groups\ue2\u20ac\u201dthat represent populations with higher numbers of risk factors. Thus, estimates of health risk behaviors and conditions have increased. In addition, the move to a new method of weighting the data increased in many states the prevalence estimates of chronic diseases such as diabetes and of risk factors such as obesity. Although raking might cause state prevalence trends for certain risk factors to shift upward, in general, the shape of trend lines over time might not be affecte
