A record 47.3 percent of salaried workers showed abnormal readings in their health checkups last year, according to a government survey released Saturday.

The ratio of workers with health abnormalities has risen each year over the past decade, the Health, Labor and Welfare Ministry said. The figure in the latest survey was up 13.7 percentage points from 1993.

The ministry compiled the study based on the results of regular health checkups on company workers. About 37 million workers are supposed to undergo medical checkups each year, but usually only about 80 percent of that number do so, it said.
