[Growth follow-up of infants born macrosomia at their life of 0 to 18 months].
OBJECTIVE
To study the growth of macrosomic infants, the incidence of overweight and the factors related to overweight at 18 months old.


METHODS
Eighty-four macrosomic infants without underlying diseases were enrolled in this study. Their growth was followed up regularly. Factors related to overweight at 18 months old were investigated.


RESULTS
Twenty infants (24%) showed as overweight at 18 months old. More male infants were overweight than female infants (30% vs 11%; P<0.05). The overweight infants at 18 months old had a higher proportion of overweight at 6 months (80% vs 22%; P<0.01) and at 12 months old (80% vs 13%; P<0.01) than non-overweight infants at 18 months. The spearman correlation analysis demonstrated that weight-for-length Z score at 18 months old was positively correlated with birth weight and weight gain between 0 to 6 months, 7 to 12 months and 13 to 18 months (P<0.05). The strongest correlation was observed between weight gain form 0 to 6 months and weight-for-length Z score at 18 months old (r=0.597, P<0.01).


CONCLUSIONS
More attention should be given to the aspect of rapid weight gain in the first 6 months of life in macrosomic infants, especially males, to prevent obesity in early childhood.
