Five-year prospective analysis of dietary intake and clinical status in malnourished cystic fibrosis patients
Poor growth and malnutrition still pose a problem in cystic fibrosis (CF). The aim of the present study was to assess nutrition, as well as clinical status, of malnourished CF patients during a nutritional care programme. Material and methods
The study comprised 38 CF patients, aged 1–18 years old. The prospective annual assessment of dietary intake and clinical status was carried out during 1994–98. Results
The energy intake increased, in comparison with recommended daily allowances, from 83.6 ± 4.8% in 1994 to 107.9 ± 4.9% in 1998. A similar tendency was observed for the percentage of energy derived from fat (30.3 ± 0.8% versus 35.1 ± 0.8%) and protein (11.4 ± 0.4% versus 13.8 ± 0.4%). In subsequent years of the study, an improvement in the fat profile of the diet (with a higher consumption of polyunsaturated fatty acids) was observed. The observed increase of vitamin A and E consumption was related chiefly to changes in the doses of supplementation. During these 5 years, an improvement in nutritional status (Z-score: height −1.34 ± 0.13 versus −1.08 ± 0.14 and weight −1.40 ± 0.09 versus −1.12 ± 0.08) and lung function (forced expiratory volume in 1 s: 75.5 ± 2.0% versus 77.8 ± 2.2%) was observed. Conclusion
The nutritional care programme resulted in stable quantitative and qualitative changes in dietary intake. Although the diet does not reach the recommended level of high-energy intake, the positive impact of increasing nutrient intake on the nutritional and clinical status of malnourished CF patients was documented.
