Maybe way off but after no information on this event turned up I wondered if RuSHA influence, racial theory, eugenics, or the fairly new Nurnberg laws may have been a few of the topics of this 1937 hygiene exhibition.
According to wikipedia, prosecutions of some Nurnberg laws didn't begin until after the 1936 olympics due to foreign policy concerns.
The May/June 1937 date didn't seem too far off from olympics closing date.
