Screening postnatal growth
Growth is the fundamental process characterizing childhood. The growth follow-up is an important component of preventive health care in children. Insufficient growth might be the initial indicator of an underlying disease. Some growth parameters specified for populations are used to follow growth in children. Among them are height, body weight, head circumference; and arm span and upper to lower body segment ratio for assessing the proportions of the body segments. The recommended follow-up intervals and criteria for insufficient growth differ according to ages. Postnatal growth rate should ideally be calculated in a 12±3 months period. Genetic potential should also be considered when growth pattern is evaluated.
