Quizplus · Accepted Answer

The reduced activity of an enzyme dependent on thiamine and the absence of signs of beriberi suggest an intermediate stage of thiamine deficiency. This stage may be caused by poor intake of thiamine or other factors that impair the body's ability to absorb or use thiamine. It is not the final stage where health is at risk, nor is it necessarily the first stage where thiamine stores are depleted.
