Values are mean ± standard deviations expect the frequencies of the weight categories within each menopausal group that are presented as as percentage and highlighted with italics.
BMI = body mass index, E2 = 17β-estradiol, ERMA, Estrogenic Regulation of Muscle Apoptosis; FSH = follicle-stimulating hormone.
aKruskal-Wallis test was used.
bDue to uncompleted prequestionnaires, missing values were found for height (post, n = 1), weight (pre, n = 2; late peri, n = 1; post, n = 4), and BMI (pre, n = 2; late peri, n = 1; post, n = 4).
