The height, weight, and head circumference of a child can be compared to the expected parameters of children of the same age and sex to determine whether the child is growing appropriately. Growth charts can also be used to predict the expected adult height and weight of a child because, in general, children maintain a fairly constant growth curve.
Failure to thrive (FTT), also known as weight faltering or faltering growth, indicates insufficient weight gain or absence of appropriate physical growth in children. [ 2 ] [ 3 ] FTT is usually defined in terms of weight, and can be evaluated either by a low weight for the child's age, or by a low rate of increase in the weight.
Low maternal vitamin B 12, defined as serum concentration less than 148 pmol/L, increases the risk of miscarriage, newborn low birth weight and preterm birth. [ 36 ] [ 34 ] During pregnancy the placenta concentrates B 12 , so that newborn infants have a higher serum concentration than their mothers. [ 33 ]

Other studies classify SGA babies as those with birth weight values below the 10th percentile of the growth chart for babies of the same gestational age. [25] This indicates that these babies are weighing less than 90% of babies of the same gestational age.
