The coronavirus pandemic has impacted the development of children ages 5-9 in several key ways: 1) Daily life changed dramatically with school closures, lack of socialization, and mandated social distancing and masks. This disrupted their physical, social, and learning environments. 2) Brain development may have been hindered by the loss of in-person learning support and increased stress at home. Emotional development also suffered without peer socialization opportunities. 3) Physical health declined for some as access to nutritious meals decreased and sedentary behaviors increased while stuck at home.
