Parent-reported birth information: birth weight,birth length and gestational age. Validation study in the SENDO project

ObjectiveTo test the validity of parent-reported birth information obtained through an online, self-administered questionnaire.MethodThe SENDO project is a prospective and dynamic paediatric cohort of Spanish children aged 4 to 6 years old at recruitment. Objective data from medical birth records were compared to parent-reported data getting intra-class correlation coefficients (ICC) for quantitative variables and weighted Kappa Index for qualitative ones. Percentage of responders and of total agreement was also evaluated.ResultsParental response rate was over 99% for birth weight and gestational age and 76% for birth length. ICC for birth weight was 0.95 (95% confidence interval [95%CI]: 0.94-0.96) and 0.78 (95%CI: 0.73-0.83) for birth length, both showing very high correlations. The total agreement percentage for gestational age was 97%, and Kappa weighted index was 0.90 (95%CI: 0.89-0.90), showing a very high agreement as well.ConclusionsWe found high correlations and excellent agreement in parent-reported birth data 4 to 6 years after delivery. Our results show parent-reported birth data, especially birth weight, are valid for use in epidemiological research.     

新生儿体重与优生─附13140例分析

回顾性分析了１２年来１３１４０例新生儿体重及相关因素。新生儿初生体重由１９８２年的３０５０±５７６ｇ上升至１９９３年的３３１７±４２９ｇ。低体重儿发生率由６．４％降至２．９％。大胎儿的发生率由１７．８％升至３１．８％。大胎儿剖宫产率、产后出血、新生儿窒息及第二产程延长的发生率均明显高于正常体重儿。提出预防低体重儿和大胎儿并重的原则。     

Radiological Demonstration of Small Bowel Adaptation Following Modified Scopinaro Procedure for Morbid Obesity

Upper gastrointestinal contrast studies were carried out on 24 patients at progressive time intervals following gastric partition with partial biliopancreatic bypass (modified Scopinaro procedure) for morbid obesity. Roentgenograms taken on standardized equipment were compared in order to document adaptive changes occurring in the small bowel with time following the procedure. Mucosal fold thickness and bowel lumen calibre within the terminal ileum were found to increase significantly with (log) time. Such adaptation of the ileum is well recognized following jejunoileal bypass, but radiological demonstration after biliopancreatic bypass has not been described previously. Mucosal hypertrophy and increase in bowel lumen calibre should be recognized as normal adaptive changes in the small bowel and not be misinterpreted as evidence of underlying pathology. Whilst adaptation following jejunoileal bypass undoubtedly contributes to eventual weight gain following surgery, this detrimental effect following the modified Scopinaro procedure appears to be negated by the reduced intake and maldigestion imposed by this procedure.
