Small-area estimation on current asthma prevalence among adults in Massachusetts using BRFSS survey data
Methods: We developed a multilevel, mixed-effect logistic regression model to estimate and compare municipality level of asthma prevalence among adults using pooled 2008, 2009 and 2010 MA BRFSS survey data, other related administrative data, and 2010 American Community Survey population estimates. The analytic sample included more than 52,000 respondents with an average age of 54 years, 63% women, 17% racial/ethnic minorities, 63% college educated, and 66% household income less than $75,000. Municipality-level estimates were derived based on the model and according to socio-demographic composition and municipality characteristics.
Results: The three-year average annual state asthma prevalence estimate is 10.8%. The municipality-level prevalence estimates ranged from 8.4% to 17.2%. Urban and poor neighborhood municipalities had higher prevalence rates.
Discussion: The results will by used by MDPH and its partners to identify high prevalence municipality and prioritize municipality-based interventions in order to improve the quality of life for residents with asthma and to reduce disparities in asthma outcomes between distinct population groups.
