How about obesity? (Adipose tissue releases estrogen and cortisol.)

I strongly recommend you to read the book "Lights Out". It kind of
unify the excessive fat/carbohydrate and hormone theories. They blame
the premature puberty on "constant summer" caused by artificial
lights. If you take this together with the recent posts about
circadian rhythms and body clocks from the sci.life-extension group
you get a quite matching picture. My posts concerning the importance
of light and pineal gland can be found on Monty's forum here:

I did a library project years ago on melatonin and the link between
puberty, body mass and melatonin was known even then. Basically the
pineal produces a constant nightly secretion of melatonin which is
then diluted in body fluids. As a child grows the volume of body
fluids increases while melatonin production remains constant. The
result is that the melatonin becomes more dilute with age until it
reaches a key level (about 500pM) where it is no longer able to
inhibit the gonadotropin releasing hormone secretion, and puberty
begins.

Modern kids eat so much sugary food that they have high insulin
levels. Insulin is anabolic so they get bigger sooner and reach the
critical dilution level sooner. If you add in the "constant summer"
idea to generally lower melatonin levels it probably accelerates the
reaching of the critical point.

I must admit that I don't know much about the subject. Is there an
insulin-IGF connection (IGF: Insulinlike growth factor) involved?
Vitamin D?
