Considering the importance of iodine to support optimal growth and neurological development of the brain and central nervous system, this study aimed to assess and evaluate iodine status in Norwegian infants. We collected data on dietary intake of iodine, iodine knowledge in mothers, and assessed iodine concentration in mother’s breast milk and in infant’s urine in a cross-sectional study at two public healthcare clinics in the inland area of Norway. In the 130 mother–infant pairs, the estimated infant 24-h median iodine intake was 50 (IQR 31, 78) µg/day. The median infant urinary iodine concentration (UIC) was 146 (IQR 93, 250) µg/L and within the recommended median defined by the World Health Organization for this age group. Weaned infants had a higher UIC [210 (IQR 130, 330) µg/L] than exclusively breastfed infants [130 (IQR 78, 210) µg/L] and partially breastfed infants [135 (IQR 89, 250) µg/L], which suggest that the dietary data obtained in this study did not capture the accurate iodine intake of the included infants. The iodine status of infants in the inland area of Norway seemed adequate. Weaned infants had higher UIC compared to breastfed infants, suggesting early access and consumption of other sources of iodine in addition to breast milk.

Abstract To alleviate the re-emergence of iodine deficiency in New Zealand, two strategies, the mandatory fortification of bread with iodised salt (2009) and a government-subsidised iodine supplement for breastfeeding women (2010) were introduced. Few studies have investigated mother and infant iodine status during the first postpartum year, this study aimed to describe iodine status of mothers and infants at three, six, twelve months postpartum (3MPP,6MPP,12MPP). Partitioning of iodine excretion between urine and breastmilk of exclusive breastfeeding women at 3MPP was determined. In total 87 mother-infant pairs participated in the study. Maternal and infant spot urinary iodine concentration (UIC) and breastmilk iodine concentration (BMIC) were determined. The percentage of women who took iodine-containing supplements decreased from 46% at 3MPP to 6% at 12MPP. Maternal median UIC (MUIC) at 3MPP [82(46,157)µg/L], 6MPP [85(43,134)µg/L] and 12MPP [95(51,169)µg/L] < 100µg/L. The use of iodine-containing supplements increased MUIC and BMIC only at 3MPP. Median BMIC at all time points were below 75µg/L. Infant MUIC at 3MPP [115(69,182)µg/L] and 6MPP [120(60,196)µg/L] were below 125µg/L. Among exclusive breastfeeding women at 3MPP, an increased partitioning of iodine into breastmilk (highest proportion 60%) was shown at lower iodine intakes, along with a reduced fractional iodine excretion in urine (lowest proportion 40%), indicating a protective mechanism for breastfed infants’ iodine status. In conclusion, this cohort of postpartum women was iodine deficient. Iodine status of their breastfed infants were suboptimal. Lactating women who do not consume iodine rich foods and those who become pregnant again should take iodine-containing supplements.

Background: Breast milk is the only source of iodine for exclusively breast-fed infants. Iodine status of breast-fed infants depends on iodine in breast milk and also number of feeding in 24 hours. Iodine deficiency and iodine excess both have bad impact on infant’s health.Objective: To measure the iodine in breast milk and to evaluate iodine status of their breast-fed infants.Materials and method: This observational analytical study was carried out in the department of Biochemistry, Bangabandhu Sheikh Mujib Medical University, Dhaka with active cooperation of Kumudini Women’s 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 was used as indicator for assessing iodine status. All statistical analyses were done by using SPSS (statistical programme for social science) 12 version software package for Windows.Results: The median (range) urinary iodine concentration of lactating mothers and their breast-fed infants were 225.25 ?g/L (61.50-530.00) and 225.75 ?g/L (100.50-526.00) respectively. The median (range) breast-milk iodine concentration was 157 ?g/L (54.50-431.50) which was more than three times of recommended minimum concentration (50 ?g/L). Only 2 (4%) lactating mothers had mild biochemical iodine deficiency (UIE, 50-99 ?g/L). There was no biochemical iodine deficiency of breast-fed infants. Iodine in breast milk of lactating mothers was positively correlated with their urinary iodine excretion (p<0.01). Infant’s urinary iodine was positively correlated with iodine concentration in breast milk (p<0.01) and with urinary iodine of lactating mothers (p<0.01).Conclusion: Lactating mothers and their breast-fed infants in this study were iodine sufficient. If iodine content of breast-milk is within normal range, 10-12 numbers of feeding in 24 hours for infants is enough to get sufficient iodine from their mother’s milk.Delta Med Col J.

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 Women’s 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).  Infant’s  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.Mediscope Vol. 2, No. 1: 2015, Pages 13-17

Background: Iodine is essential for normal growth, mental development and survival of infants. Bangladesh is an iodine deficient region. Breast milk is the only source of iodine for exclusively breast-fed infants. Routine measurement of breast milk iodine concentration is very difficult in our country due to some social and religious barriers. So, we designed this study in our population using urinary iodine as the indicator for assessing iodine status. Objectives: To assess the iodine status of lactating mothers and their breast-fed infants and to propose a method on how to predict the iodine concentration in breast milk. Materials and Methods: This observational analytical study was carried out in the department of Biochemistry, Bangabandhu Sheikh Mujib Medical University, Dhaka with active cooperation of Kumudini Women’s 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. All statistical analyses were done by using SPSS (Statistical Programme for Social Science) 12 version software package for windows. Results: The median (range) urinary iodine concentration of lactating mothers and their breast-fed infants were 225.25 ?g/L (61.50-530.00) and 225.75 ?g/L (100.50-526.50). 96% (48) mothers had no biochemical iodine deficiency (UIE ?100?g/L), only 4% (2) mothers had mild biochemical iodine deficiency (UIE 50-99?g/L). There was no biochemical deficiency of breast-fed infants. The median (range) breast-milk iodine concentration was 157 ?g/L (54.50-431.50) which was more than three times of recommended minimum concentration (50 ?g/L). Iodine in breast milk of lactating mothers positively correlated with their urinary iodine excretion (P<0.01). Infant’s urinary iodine positively correlated with iodine concentration in breast milk (P<0.01) and also positively correlated with urinary iodine excretion of lactating mothers. Conclusion: Lactating mothers and their breast-fed infants in this study were found iodine sufficient. Urinary iodine concentration of lactating mothers predicts the iodine content of their breast milk. DOI: http://dx.doi.org/10.3329/jemc.v1i1.11132J Enam Med Col 2011; 1(1): 15-18
