Use of the curves weight versus age in the growth attendance from the suklings assisted at the clinic of child care

Objective: to describe the growth according to the nutritional state from the suklings assisted from a child care’s clinic, using the curves weight versus age proposed by WHO and NCHS. Methods: this is about a descriptive study, from quantitative approach, using the database from 66 infants’ handbooks. Data were analyzed in the software EPI-INFO 6.04d, SPSS 13.0 and Excel program 2003. The study has been approved by the Committee of Ethics in Research from IMIP (protocol number 1066/2007). Results: in the 1st month, the curve of WHO identified 4 (6,1%) low weight’s cases , the one from NCHS, only 1 (1,5%). Concerning to the birth’s weight, among those that were born low weight, 57,1% (4) presented low weight in the first month of life, when appraised for the curve of WHO. Whereas, the appraised infants for the curve of NCHS, 42,9% (3) had already "recovered" the weight until this age. About the feeding type, all the children that were in breastfeeding in this period, were considered with appropriate weight in both curves. Conclusion: The standard curve W x A of WHO was shown more sensitive for identification from weight’s deficits in the first months of life, in relation to NCHS.
