Except for that last part, this sounds like an argument for putting all

A third-variable problem?  The following is from PubMed:

"Evidence is presented that undernutrition and hard physical work can affect
the
natural fertility of populations, by the delay of menarche, a longer period
of
adolescent subfecundity, a longer birth interval and an earlier age of
menopause."
