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. .
