Comment about participation selection
Strengths: population based survey; developed unadjusted and fully adjusted models for analysis; high participation rate (88%); analyzed by race; analyzed the rate of mammograms in a population of obese women that is more frequently diagnosed with advanced stage of breast cancer Limitations: Did not include ORs or CI in analysis; self-reported information on mammograms and anthropometric data that could lead to error or recall bias; could not adequately control for comorbid illnesses, which are highly correlated with BMI; could not control for medical provider-related factors; unable to account for certain cancer risk factors
