Reviewer's report:  
 
It seems to me a very interesting study, with a good statistical analysis and a good correlation 
between the perception of the amount of menstrual  bleeding and the possibility even of suffering 
a deficit of iron or ferropenic anemia.  
Perhaps the study it is quite limited because it refers only  to the Afro -American population. It 
would  be better for me a comparative study with the American populati on. 
 
It could add in the bibliography the world -wide distribution of the anemia in the world according 
to graph of the WHO:"The global anemia prevalence in 2011. Geneva: World Health 
Organization;2015"
