Abstract

The objective of the observational analytical study was to assess the iodine status of lactating  mothers and their breast-fed infants and to evaluate whether maternal iodine status reflects the  iodine  status  of  their  breast-fed  infants.  The  study  was  carried  out  in  the  department  of  Biochemistry, Bangabandhu Sheikh Mujib Medical University, Dhaka with active cooperation of  Kumudini Womens Medical College Hospital, Mirzapur, Tangail involving fifty lactating mothers  and  their  exclusively  breast-fed  infants.  Early  morning  urine  and  breast  milk  samples  were  collected in dry and clean plastic container free from any chemical contamination. Urinary iodine  excretion (UIE) was used as indicator for assessing iodine status. The median (range) urinary  iodine  concentration  of  lactating  mothers  and  their  breast-fed  infants  were  225.3  ?g/L  (61.5-530.0)  and  225.8?g/L  (100.5-526.0),  respectively.  Of  the  mothers,  96%  (48)  had  no  biochemical  iodine  deficiency  (UIE  ?100?g/L),  only  4%  (2)  had  mild  biochemical  iodine  deficiency  (UIE, 50-99?g/L). There was no biochemical iodine  deficiency  of breast-fed infants.  The median breast-milk iodine concentration was 157?g/L which was more than three times of  recommended minimum concentration (50?g/L). Iodine in breast milk of lactating mothers was  positively  correlated  with  their  UIE  (p  <  0.01).  Infants  urinary  iodine was positively  correlated  with  iodine  concentration  in  breast  milk  (p  <  0.01)  and  also  positively  correlated  with  urinary  iodine of lactating mothers (p < 0.01). Lactating mothers and their breast-fed infants in this study  were iodine sufficient. Iodine status of exclusively breast-fed infants can be determined by the  iodine status of their mothers.
