小児生活習慣病予備軍の簡易スクリーニング手法の開発―要予防検診者や要生活指導者の判別について―

Abstract

The screening technique developed by the authors for lifestyle-related diseases in children is composed of 3 elements involving 18 items, and the evaluation criteria of their gradient score and total score out of 100. With the aim of expanding this technique, a survey was conducted using 6, 385 school pupils as subjects, and another survey together with a blood test was conducted using 107 obese children as subjects from whom informed consent was obtained to examine the adequacy of the 3 elements and the validity of our technique.With regard to the 18 items and the gradient score, 17 items and 15 items were respectively demonstrated to be correlated with the need for medical examination by the χ2 test and by multidimensional scaling based on the 6, 385 children. A high correct classification rate of approximately 70% was demonstrated for the evaluation criteria between the screening evaluation results and logistic discriminant analysis of the blood test results for the 106 obese children. These results confirmed the adequacy of our technique composed of 3 elements and the validity of its application in the field.The application of our technique in a regional field study showed that 274 (4.3%) were screened in our population of 6, 385 children, and that 155 (56.6% of those screened and 2.4% of the total population) were found to require medical examination. The proposed screening procedure makes it possible to identify those children who require medical examination, enabling the burden on school children and the budget involved in a mass medical examination to be reduced. The results suggest that our technique is both simple and effective.
