TNBC varies geographically, but little is known about area-level characteristics associated with elevated incidence.<h4>Methods</h4>We generated 2011-2013 age-adjusted TNBC incidence rates for state economic areas (SEAs) in 43 states using data from North American Association of Central Cancer Registries. For cases missing data on molecular markers, we imputed TNBC status using cross-marginal proportions. We linked these data to SEA covariates from national sources. Using linear ecological regression, we examined correlates of TNBC incidence rates for the overall population and for age (< 50 years or 50 + years)- or race (white or bBreast cancer (Tokyo, Japan)Triple-negative breast cancer incidence in the United States: ecological correlations with area-level sociodemographics, healthcare, and health behaviors.PMC7796916K22 CA225705Z99 CA999999Cronin KAMoss JLTatalovich ZZhu LMorgan CfalseTriple-negative breast cancer incidence in the United States: ecological correlations with area-level sociodemographics, healthcare, and health behaviors.<h4>Purpose</h4>Triple-negative breast cancer (TNBC) is an aggressive subtype of breast cancer, more commonly diagnosed among black women than other subgroups.
