Longitudinal, prospective analysis of dietary intake in children with cystic fibrosis☆,☆☆,★,★★,♢

METHODS
Subjects with CF were recruited from the CF center at Children's Hospital of Philadelphia. All subjects were adequately grown (height and weight at greater than the 3rd percentile) and had pancreatic insufficiency with mild pulmonary disease at enrollment. CF was diagnosed on the basis of clinical signs and duplicate quantitative pilocarpine iontophoresis sweat tests with sodium and chloride values greater than 60 mEq/L. Pancreatic insufficiency was based on fecal fat analysis of a 72-hour
RESULTS
Twenty-five children with CF (12 boys, 13 girls) and a healthy group of 26 children (14 boys, 12 girls) participated in the study. One child in each group had incomplete dietary data in year 0. Of 183 study evaluations completed, two diet records were returned incomplete and five were not returned. Therefore a total of 176 diet records on 51 children (81 CF, 95 control) were available for analysis. Both before and during the dietary assessment periods, a high-fat, high-calorie diet was
DISCUSSION
This 3-year study prospectively evaluated the pattern of dietary intake in pancreatic-insufficient children with CF, mild lung disease, and relatively good health in comparison with the dietary pattern in healthy control children. Although others have documented cross-sectional dietary intake in children with CF, only one group of investigators5 reported 4 years of energy intake, and this was during an intervention study rather than routine intake. In the current study, the CF group had lower

Both cross sectional and longitudinal evaluation of our study population showed an association between energy intake and particularly WFA, as was also found by others [9]. This implicates that a higher caloric intake especially has an impact on weight (gain).
