Epidemiology

edit

Blue Baby syndrome or methemoglobinemia mostly affects infants under 6 months of age, although the age range it is most common in is 0 to 4 months. Infants in this age range are vulnerable because they haven't matured enough to produce methemoglobin reductase, an oxygen carrying molecule. [1] [2] The most at risk populations are those with private water sources. Private wells aren't regulated by the US government and therefore, if unmonitored, can have higher levels of nitrates; being hazardous to the infants. [3][4] The link between Blue Baby Syndrome in infants and high nitrate levels is well established for waters exceeding the normal limit of 10 mg/L.[5][6] However, there is also evidence that breastfeeding is protective in exposed populations[7]. Its recommended to have your drinking water tested by a state certification officer if you suspect a problem, many laboratories will provide a water test free of charge. Residents of the United States can find a list of cost-free laboratories here.
