Deficiency Anemia among Female Students

Reviewer's report:
This study was to test the effects of nutrition education in order to prevent iron
deficiency anemia based on the PRECEDE model among female middle school
students. 
It is important for students to obtain appropriate health behaviors through health
education in early stage.
Sample size for intervention group is 80, pretty big, so I wonder how many
people you made a small group to be effective, and the how many groups you
had for each session. 
As I expected for education program, 
study results showed the effect of
nutritional education on knowledge, attitude and behaviors. 
However, there were no significant increases in levels of hemoglobin and
hematocrit but ferritin level between two group. 
As I know, three physiologic indicators are closely related each other.
Participants are very healthy group when I saw levels of hb, hct, and ferritin. 
Therefore, I wonder why and how hb, hct and ferritin did not improve all
together if this program is effective to change their behavior as you said. Please
provide a reasonable explanation.
It is very hard to improve hemoglobin level by only diet intake. Please explain it
is enough to increase level of ferritin within 4 months by diet behavior
