OBJECTIVE: To evaluate the impact of congenital heart diseases in growth of children with Down syndrome (DS) and the weight-height recovery after surgical correction. METHODS: Retrospective study of the DS patients between 1984 and 2007. Excluding the mosaics and/or patients with associated morbidities (n=165). Calculated Z scores for weight (Zwb) and length (Zlb) at birth. Those patients submitted to surgical correction (n= 60) these scores (Zw/Zh) were evaluated before surgery and in subsequent periods to five years. Malnutrition was defined as weight/height Z-score < 2.5. Used Chi-square test to verify the relation between weight/length and age at the time of surgery and Student T test to evaluate the postoperative (PO) time of recovery (P < 0.05). RESULTS: Means Zwb (n = 162) and Zlb (n = 156) were -0.95 ± 1.27 and -1.348 ± 1.02. From the total data (n = 165), 65.5% (n = 108) presented heart disease. Those submitted to cardiac surgery (n = 60), Zw was below -2.5 in 55% (n = 33) and Zh in 60% (n = 36). After six months PO, 67.4% achieved Zw > 2.5. In one year, 85.7% achieved Zh > 2.5. Dividing this group by age in tertiles at time of surgery no difference was found. CONCLUSIONS: We concluded that malnutrition common in children with DS since birth. DS children with congenital heart and surgical indication were smaller and lighter than those without or with mild disease. PO recovery occurred in 6 months for weight and one year for height, with no difference in the age at the time of surgery.
