In a significant finding, scientists have discovered that environmental factors play a greater role than genetic variants in determining the height of children in low- and middle-income countries (LMICs) in contrast to those from European nations, where genetic aspects predominate in regulating childhood height. Human height is strongly influenced by fixed genetic and variable environmental factors. Fixed genetic factors are those that are inherited from our parents and cannot be changed. Variable environmental factors are those that can change over time, such as diet, nutrition, and access to healthcare.
