Correlation between iodine load of pregnant women and infant growth and development in Lishui City

Objective]To investigate the status of maternal iodine deficiency in Lishui City of Zhejiang Province,and explore the effect of maternal iodine deficiency on the growth and development of infants.Methods]A total of 209 pregnant women living in Liandu District of Lishui City from January 2017 to December 2018 were selected by stratified sampling method.Urine iodine level in pregnant women and iodine content in edible salt at home were determined to assess the status of iodine deficiency and to analyze the influencing factors.Their babies were followed up for 1 year,and metabolic disease screening and physical examination were carried out to evaluate the growth and development.Results]The median of urinary iodine levels in 2017 and 2018 were 165μg·L^-1and 192μg·L^-1,respectively.Both of the values met the standard of iodine sufficiency.The results of salt iodine content in pregnant women’s homes showed that 7 cases(3.35%)were without iodized salt and 202 cases(96.65%)with iodized salt,including 186 cases(89.00%)with qualified iodized salt.Univariate analysis showed that pregnancy,education level,intake of iodized salt,cooking methods of salt,intake frequency of iodine-rich food and knowledge of iodine nutrition had significant impact on iodine deficiency in pregnant women(P<0.05).Logistic regression analysis showed that early pregnancy(OR=1.626)and adding salt into heat oil(OR=1.874)were risk factors for iodine deficiency in pregnant women,while intake of qualified iodized salt(OR=0.593)was a protective factor.Follow-up results showed that there were no abnormalities in newborn screening,and babies of 2 women(2.41%)with iodine deficiency were short in height at 1,6 and 12 months of age.Conclusion]Attention should be paid to the monitoring of pregnant women’s urinary iodine levels to guide the scientific supplementation of iodine,so as not to affect the growth and development of infants.
