Nearly half of all adults age 30 years or older in the United States are affected by periodontitis. A Healthy People 2020 objective is to reduce the prevalence of moderate and severe periodontitis in US adults. To address the problem it’s important to know where the prevalence is highest and target effective programs for those populations. Currently the state and local levels of periodontitis are not well characterized, yet this is where most of the public health programs are instituted.
The assessment focused on obtaining an estimate of the prevalence of periodontitis among adults age 30 to 79 years at state, county, congressional district, and census tract levels based on data from the National Health and Nutrition Examination Survey (NHANES) 2009-2012, population counts from the 2010 US census, and smoking status estimates from the 2012 Behavioral Risk Factor Surveillance System. The small area estimation (SAE) method used age, race/ethnicity, gender, smoking status, and
The model-based estimates were statistically similar to the NHANES estimates at the national level and within the subgroups of gender, age, race/ethnicity, smoking status, and poverty status. At the state level, the model estimated a low prevalence of 37.7% in Utah up to a high of 52.7% in New Mexico, which represented an estimated 15% disparity among the states.
At the county level, the low was 33.7% and the high was 68%, with a mean of 46.6% and a median of 45.9%. The disparity among states
The use of MRP modeling of individual- and community-level data can provide a practical and valid way to predict the prevalence of adult periodontitis at state and local levels in the United States. It also allows the incorporation of individual-level risk factors such as poverty and smoking status to predict population health outcomes.
