Insights
Birth parameters and parental height significantly impact long-term growth in children with chronic kidney disease (CKD). Poor growth outcomes are linked to lower birth weight, length, and parental height, highlighting key predictive factors.
Area of Science:
- Pediatric Nephrology
- Growth and Development
- Chronic Kidney Disease Research
Background:
- Investigating factors influencing growth in pediatric chronic kidney disease (CKD) stages 3-5.
- Understanding the long-term growth trajectory for children with CKD is crucial for management.
- Assessing the role of early life factors in pediatric CKD outcomes.
Purpose of the Study:
- To analyze the impact of birth parameters and parental height on long-term growth outcomes in children with CKD stages 3-5.
- To identify predictors of poor growth in this vulnerable pediatric population.
- To establish the relationship between prenatal and perinatal factors and subsequent growth in children with CKD.
Main Methods:
- Prospective linear growth investigation in 509 children with CKD (stage 3-5) over a mean follow-up of 4.1 years.
- Categorization of growth outcome into poor growth (PG; height SDS < -2.0 and/or GH treatment) and good growth (GG; height SDS ≥ -2.0).
- Multivariate binary logistic regression analysis to determine predictors of poor growth outcome.
Main Results:
- 55% of children experienced poor growth (PG).
- Pre-term birth and being small for gestational age were significantly higher in the PG group (43.2% vs 25.6% and 36.8% vs 18.9%, respectively; p < 0.001).
- Lower birth length, umbilical cord pH, and parental height were significant independent predictors of poor growth (sensitivity 72.8%, specificity 69.3%).
Conclusions:
- Birth parameters and parental height are independent predictors of growth outcome in children with CKD.
- Early life factors, including birth measurements and genetics (parental height), play a critical role in long-term growth.
- These findings emphasize the importance of considering birth history and parental stature in managing growth in pediatric CKD.
Background:
We analyzed the impact of birth parameters and parental height on long-term growth outcome in children with chronic kidney disease (CKD) stage 3-5.
Methods:
Linear growth was prospectively investigated in 509 children, with a mean follow-up of 4.1 years. Growth outcome was categorized in (i) poor growth (PG): height standard deviation score (SDS) during follow-up < -2.0 and/or actual or previous growth hormone (GH) treatment, and (ii) good growth (GG): height SDS ≥ -2.0 and no need for GH. A multivariate binary logistic regression model was constructed for predictors of PG outcome.
Results:
PG was observed in 55 % of patients. The rate of pre-term and small for gestational age birth was significantly higher in children with PG compared to GG (43.2 vs. 25.6 % and 36.8 vs. 18.9 %; p < 0.001). Children with PG had significantly lower average values for gestational age, birth weight, length, and head circumference, umbilical cord pH, Apgar scores, and parental height than children with GG. Birth length, umbilical cord pH, and parental height were significant independent predictors of PG outcome (sensitivity 72.8 %, specificity 69.3 %).
Conclusions:
Birth parameters and parental height are independent predictors of growth outcome in children with CKD.
