Children with cystic fibrosis in South Africa: an improving nutritional picture
1Department of Paediatrics and Child Health, Red Cross War Memorial Children's Hospital, University of Cape Town, South Africa. Westwood@ich.uct.ac.za
Insights
Improved growth in South African children with cystic fibrosis (CF) was observed between 1986 and 1996. This nutritional status enhancement in young CF patients suggests a better long-term prognosis in resource-limited settings.
Area of Science:
- Pediatric Nutrition
- Genetic Disorders
- Public Health
Background:
- Nutritional status and growth are critical determinants of prognosis in cystic fibrosis (CF).
- South African CF patients have a median survival of 18 years, highlighting the need for improved management.
- Understanding growth patterns is essential for enhancing patient outcomes in CF.
Purpose of the Study:
- To analyze the longitudinal growth patterns of a South African cystic fibrosis (CF) population.
- To assess changes in nutritional status indicators over a decade (1986-1996).
- To evaluate the impact of interventions on growth in a resource-limited setting for CF patients.
Main Methods:
- Retrospective chart review of CF patients in South Africa.
- Calculation of weight-for-age, height-for-age, and weight-for-height indices for 1986 and 1996.
- Statistical comparison of growth indices between the two study periods.
Main Results:
- Mean nutritional indices remained consistent between 1986 and 1996 for the overall CF population.
- Children aged 5-10 years showed a significant improvement in mean weight-for-age in 1996 (94.2%) compared to 1986.
- This improvement represented a 14.3% increase, indicating enhanced growth in younger CF patients.
Conclusions:
- Significant improvements in the growth of young children with cystic fibrosis have been achieved in South Africa.
- These findings suggest that enhanced nutritional status can positively influence the prognosis of CF patients.
- The study demonstrates the feasibility of improving CF patient outcomes even in resource-poor environments.
Abstract:
Nutritional status and growth play an important part in determining the prognosis in cystic fibrosis (CF). In South Africa, the median survival of patients with CF is 18 years. Using chart review, we studied the pattern of growth over time of a South African CF population. The percentages of expected weight-for-age, height-for-age and weight-for-height were determined for each patient in 1986 (n = 49) and 1996 (n = 63). Mean indices were the same in the two years. In 1996, mean weight-for-age of children aged 5-10 years was 94.2 per cent (SD 20.4), 14.3 per cent higher (p < 0.05, 95 per cent confidence intervals 3-25 per cent) than children of the same age in 1986. Improved growth of young children with CF has been achieved in a resource-poor country setting the scene for improved prognosis.

CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation, but...
