Growth trajectories in children with cleft lip and/or palate.

Introduction: the nutritional status and growth of children with cleft lip and/or palate (CL/P) can be affected due to feeding difficulties caused by their anatomy and the surgical interventions. Objective: this retrospective longitudinal study aims to analyse the growth trajectories of a cohort of children with CL/P and compare them with a healthy representative cohort of children from Aragon (Spain). Methods: type of cleft, surgical technique and sequelae, and weight, length/height and body mass index (BMI) (weight/height2) at different ages (0-6 years) were recorded. Normalized age- and sex-specific anthropometric Z-scores values were calculated by World Health Organization (WHO) charts. Results: forty-one patients (21 male, 20 female) were finally included: 9.75 % cleft lip (n = 4/41), 41.46 % cleft palate (n = 17/41) and 48.78 % cleft lip and palate (n = 20/41). The worst nutritional status Z-scores were achieved at the age of three months (44.44 % and 50 % had a weight and a BMI lower than -1 Z-score, respectively). Mean weight and BMI Z-scores were both significantly lower than controls at one, three and six months of age, recovering from that moment until the age of one year. Conclusions: the highest nutritional risk in CL/P patients takes place at 3-6 months of age, but nutritional status and growth trajectories get recovered from one year of age compared to their counterparts. Nevertheless, the rate of thin subjects among CL/P patients is higher during childhood.
