Low-level @entity349 ( @entity5332 ) exposure in infancy might be harmful to the physical growth as well as neurodevelopment of @entity1 . The aim of this study was to investigate postnatal @entity5332 exposure and its relationship with anthropometry and dietary factors in late infancy. We recruited 252 healthy Korean @entity1 between six and 24 months of age from an outpatient clinic during the 2009/2010 and 2013/2014 seasons. We measured the weight and height of the @entity1 and collected dietary information using questionnaires. The @entity5332 content of the hair and blood was assessed using inductively coupled plasma mass spectroscopy. The geometric mean @entity5332 concentration in the hair and blood was 0.22 (95% confidence interval: 0.20-0.24)   g/g and 0.94 (n = 109, 95% confidence interval: 0.89-0.99)   g/L, respectively. The hair @entity5332 concentration showed a good correlation with the blood @entity5332 concentration (median hair-to-blood @entity5332 ratio: 202.7, r = 0.462, p < 0.001) and was >1   g/g in five @entity1 . The hair @entity5332 concentration showed significant correlations with @entity1017 after birth (Z-score of the weight for age-Z-score of the birthweight; r = -0.156, p = 0.015), the duration (months) of breastfeeding as the dominant method of feeding (r = 0.274, p < 0.001), and the duration of fish intake more than once per week (r = 0.138, p = 0.033). In an ordinal logistic regression analysis with categorical hair @entity5332 content (quartiles), dietary factors, including breastfeeding as the dominant method of feeding in late infancy (cumulative odds ratio: 6.235, 95% confidence interval: 3.086-12.597, p < 0.001) and the monthly duration of fish intake more than once per week (cumulative odds ratio: 1.203, 95% confidence interval: 1.034-1.401; p = 0.017), were significantly associated with higher hair @entity5332 content. @entity1017 after birth was not, however, significantly associated with hair @entity5332 content after adjustment for the duration of breastfeeding as the dominant method of feeding. Low-level @entity5332 exposure through breastfeeding and fish intake as a complementary food did not directly affect anthropometry in this population. If prolonged breastfeeding is expected, however, the @entity5332 exposure through fish intake may need to be monitored for both mothers and @entity1 .
