Table 3 shows the results of the multiple
linear regression analysis. After adjusting
for confounding variables, researchers
observed that pregnant women of the After
mandatory flour fortification group had a
mean Hb concentration that was 0.17g/dL
higher than that of the Before fortification
group. Pregnant women with a paid job
and a partner also showed higher Hb levels.
Negative coefficients were identified for the
“gestational age in the first consultation”
and “number of previous pregnancies”
variables, with significant decreases in
Hb levels as the gestational age in the first
prenatal consultation and the number of
previous pregnancies increased.
