Cádmio no leite materno: concentração e relação com o estilo de vida da puérpera

Abstract

Purpose: To relate the cadmium concentration of colostrum with the lifestyle of women in the puerperium period. Methods: A cross-sectional study was conducted in Goiânia, Goiás (Mid-western Region of Brazil). Eighty women, according to inclusion criteria, were interviewed about their socioeconomic characteristics and lifestyle. They answered a questionnaire about food frequency consumption (FFQ). The colostrum samples collected were analyzed by flame atomic absorption spectrometry to quantify cadmium levels. For statistical analysis, central tendency measures were obtained, and the Mann-Whitney and Kruskal-Wallis tests were performed, as well as correlation and regression tests. Results: The average cadmium concentration was 2.3 μg/L and the median was 0.9 μg/L. Variables such as age and parity showed a nonsignificant positive correlation with cadmium. Smoking habit was not significantly associated with cadmium. Conclusions: Postpartum food intake influences the level of cadmium in colostrum, especially vegetables such as cereals.
