Resumo
Introduction: considering the importance of iron to infant health, and knowing
that, in addition to nutrients colostrum may contain contaminants (cadmium and
lead) from exposure to environment and nutrition of pregnant women, the
relationship between these factors and heavy metals from the colostrum got
enhanced. Objectives: to assess the relationship of the concentration of
cadmium, lead and iron in colostrum with socioeconomic, lifestyle and dietary
intake of pregnant women and recent mothers. Methodology: cross-sectional
study with 80 lactate mothers in a maternity hospital in Goiânia (GO/Brazil).
Socioeconomic, demographic and food frequency consumption (FFQ)
questionnaire was applied and heavy metals colostrum by flame atomic
absorption spectrometry were quantified. Results: median cadmium was 0.93
μg/L, and lead 4.65 μg/L in colostrum. There was no significant difference
between age and region where puerpera lived in and contaminants, but there
was a positive correlation, and the averages were higher for women over age of
20 and that were living in the capital, Goiânia. Cholesterol (p = 0.041) and
animal products (p = 0.020) correlated significantly with lead. Grains such as
rice (p = 0.042) influenced the cadmium colostrum positively. Iron content of the
median value was 128.94 μg/L, with no significant association with the
supplement and food consumption. Conclusions: relationship was detected
between cadmium and lead content in colostrum with food consumption. The
iron did not correlate with dietary factor. Socioeconomic factors, smoking,
alcohol consumption and food supplementation had no significantly association
with concentrations of the metals studied.
