Child Growth Standards

The World Health Organization has published standards for child growth that are based on the National Center for Health Statistics (NCHS). These standards were developed after combining 2 separate datasets: the Ohio Fels Research Institute Longitudinal Study conducted from 1929 to 1975 and the United Kingdom’s Birth Cohort. The new growth reference is based on the height-for-age z-score, and is more accurate for children who are not breastfed.

The environment, disease, personal care and early sanitation can affect a child’s development

The development of children’s bodies is a complex process that includes increased body mass, morphological remodeling, and functional maturation. These three phases define a child’s physiological characteristics and help differentiate them from adults. However, many factors can influence the development of a child, including the environment, disease, personal care, and basic sanitation conditions. Therefore, it is important to understand how these processes occur to ensure that your child is able to reach their full potential.


During the first two years of life, children develop in three basic stages. The first two years of development are the most important, and a child’s growth will differ from their parents’. Throughout childhood, children will grow at varying rates. The second year is typically when they reach their full physical potential, while the third stage is when their body size begins to decline. This process is also critical in determining what children should not eat.
