Are children with clefts underweight for age at the time of primary surgery

Children with clefts, especially those with a cleft palate, have an impaired sucking mechanism and are therefore prone to nutritional problems. This study was undertaken to determine whether children with clefts of the lip and/or palate are underweight for age at the time of primary surgery. Underweight for age was defined as being less than 80 percent of expected weight for age or below the 3rd percentile as plotted on standard percentile charts. The records of all children with clefts seen at the Red Cross Children's Hospital between 1976 and 1996 were reviewed. Of these 740 records, 100 were excluded for inadequate data ( 47), severe systemic syndrome (27), no operation done (22), or craniofacial cleft (4). The records of 640 children were thus included; 195 (30.5 percent) were underweight for age. By comparison, only 13.7 percent Of a similar group of noncleft controls (n = 872) were underweight for age. The difference between these two groups was highly significant (p < 0.01). Factors that influenced weight at the time of primary surgery were type Of cleft and age at the time of surgery. Children with cleft palate, whether associated with a clef; lip or not, were found to be more underweight for age than those with art isolated unilateral cleft lip (p = 0.008). Children who had surgery after the age of 1 year were 1.5 times more likely to be underweight fur age than children who had surgery under 1 year of age (p < 0.01). Children with isolated cleft palates who were underweight for age had a tendency toward a higher fistula rate (36 percent) than those of normal weight (24 percent) (p = 0.18).
