A noninvasive SpHb measurement study of 12,714 Japanese children aged 1 to 5 estimated the proportion suspected of having anemia at 4.1% and newly identified a positive correlation between follow-up formula intake among 1-year-olds and estimated blood hemoglobin concentration.
When estimated blood hemoglobin concentration was measured in Japanese children aged 1 to 5 using a noninvasive hemoglobin measurement device, the proportion suspected of having anemia was estimated at 4.1%. The study also showed that the proportion ranged from 2.3% to 6.6% among subgroups by sex and age in months. The study included a total of 12,714 children whose consent was obtained through baby specialty stores and other locations nationwide, and measured SpHb.
A new positive correlation was also identified between follow-up formula intake and SpHb among children aged 12 to 23 months. The analysis is positioned as suggesting that intake of iron-fortified follow-up formula may affect estimated blood hemoglobin concentration.
