Analysis on relationship between iodine nutrition of infant and lactation

ObjectiveTo discuss relation of iodine nutrition of infant and lactation.MethodUrinary iodine between lactating womam and its infant were paired off and were analyzed by correlation and regression analysis;Urinary iodine was measured by ammonium persulfate digestion-arsenic cerium catalysis spectrophotoemtry.ResultsUrianry iodine between lactating woman and infant correlated markedly,correlation coefficient(r)was respectively 0.344(P<0.01)in 179 pairs on 0~14 month infants and 0.524(P<0.01)in 97 pairs on 0~7 month infant;regression equation was respectively ŷ=214.20+0.677x and ŷ=136.517+1.178x.Correlation coefficient(r)was statistically significantin 0 month~,4 month ~group infant.ConclusionUrinary iodine between lactating woman and infantis better correlation in 0 month~,4 month ~group infants,correlation coefficient(r)descended with the aging of infant.
