National statistics on multiphasic health testing (human dock and AMHTS)--especially for the annual-course change during the last five years.

We have gathered national statistics on multiphasic health testing since 1984, and especially analyzed annual-course changes of the past five years. 1) Subjects for questionnaire survey: Despite an increasing number of hospitals with human dock and institutions with automated multiphasic health testing and services (AMHTS), the reply rate to the questionnaire survey has also increased with the number of subjects for the survey being 900,000 in 1988. 2) In the survey of national statistics under the internal organ distinction, the detection rate of cancer of the stomach was the highest, followed by the rates of cancers of the large intestine and lung, in that order. The rate of cancer of the stomach to all the detected cancers decreased by 11.1% during these five years, whereas that of cancer of the large intestine increased to represent 40% of the rate of the stomach. The rate of early stage cancer for all cancers was high, for example, approximately 70% for the stomach and 75% for the large intestine, proving that multiphasic health testing provides excellent accuracy. 3) In the total results collected under item distinction, we examined six items (obesity, glucose tolerance failure, hepatic defficiency, hypertension, hypertriglyceridemia and hypercholesterolemia) which appear frequently and become sources of adult disease. We concluded that especially, hepatic deficiency and hyperlipidemia had increased each year, indicating a deterioration of health and also that regional differences showed a decreasing tendency. 4) The present analysis of the national statistics has apparently provided effective information as data of a preventive counterplan against adult disease.
