According to the World Health Organization, the cutoff hemoglobin (Hb) value for defining anemia is 11 g/dL in preschool-aged children, and Hb measurements should be corrected above an altitude of 1000 meters. This study sought to determine the altitude at which the Hb value increases compared with that at sea level, Hb changes with age and region in Peru, the prevalence of anemia according to three different models used to correct Hb for altitude, and the association of the Hb value with stunting. Two individual-based Peruvian national databases were analyzed. Hb increased from an altitude of 375 meters. Hb concentration was lower at younger ages and higher at older ages. The increase in Hb with increasing altitude was lower in southern Peru. Implementing the different models for Hb measurement correction resulted in a higher and lower prevalence of anemia at altitudes >2500 and <2500 m, respectively, using the CDC adjustment. In children aged 6-23 months, the rate of stunting was lower in those with an Hb level of 10-12 g/dL (including mild anemia). In conclusion, the adjustment of Hb values for altitude should be considered before 1000 m and reference ranges should be adjusted to smaller groups of children instead of the same reference range for children aged 6-59 months.

Addressing racial bias in early childhood is crucial for fostering inclusivity and reducing social inequalities. This study examined the effectiveness of individuation training in reducing racial bias among Canadian preschool-aged children and explored how interracial contact might influence changes in children's implicit anti-Black bias. A total of 113 preschool-age children (60 females, M = 5.

Background: The promotion of a healthy lifestyle among preschool children is essential for establishing their future habits. Evidence indicates that the incorporation of philosophical thinking-encompassing critical, creative, and compassionate thought-can significantly contribute to children's cognitive and moral growth, thereby positively affecting their health-related decisions. This research evaluated the effects of imparting healthy lifestyle practices through philosophical thinking to preschool children.

Parental emotion socialization is crucial to children's development, yet emotion-focused parenting programs are scarce in non-Western contexts. In this study, we developed a four-week emotion-focused parenting program based on the principles of emotion coaching for Chinese families with preschool-aged children. This program integrated parent group sessions with home-based parent-child shared reading.

Background: Movement behaviors, including physical activity (PA), sedentary behavior (SB), and sleep, are fundamental to early childhood development. These behaviors interact dynamically within a 24-hour period, creating a complex balance that influences not only physical health but also cognitive and emotional well-being in young children. While the physical health benefits of movement behaviors are well-documented, systematic evaluations of how interventions targeting these behaviors affect cognitive development in preschool-aged children remain limited.
