Core Tip
Core tip: Prenatal and early childhood estimators of growth, such as birth weight, height etc. by themselves are inadequate measures for inter-individual comparison, unless accompanied by gestational or chronologic age. The existing evidence points toward an association between indoor air pollution and growth, however few considered age. In order to establish a causal relationship it is imperative to consider age adjusted growth.
