Perimenstrual chocolate craving. What happens after menopause?

Abstract:
About half of American women crave chocolate, and approximately half of the cravers crave it specifically around the onset of menstruation. This study examines whether the primary cause of this "perimenstrual" craving is a direct effect of hormonal changes around the perimenstrum, or rather if the craving is a general response in some individuals to stress or other notable events. Insofar as there is a direct hormonal effect, one would predict a substantial decrease of 38% in total chocolate craving in women post-menopause, corresponding to the proportion of women pre-menopause who report craving chocolate exclusively perimenstrually. Based on a survey of pre- and post-menopausal alumnae of the same University, we report a significant but small decrease in prevalence of chocolate cravings post-menopause. The decrease is only 13.4% and thereby much smaller than a 38% drop predicted by a purely hormonal explanation, suggesting that female reproductive hormones are not the principal cause of perimenstrual chocolate craving.

Hormonal Regulation of the Menstrual Cycle
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH release.

Hormonal Control of the Ovarian Cycle
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...
Menses Phase
When fertilization does not occur, the corpus luteum deteriorates, causing a significant drop in the levels of estrogen and progesterone in the body. This hormonal decrease triggers the release of prostaglandins, which cause the uterine...
