Diabetes mellitus and its effects on menarche.
In a combined mail and medical record survey of 121 non-diabetic and 90 diabetic girls greater than or equal to 9 years of age, the mean age of menarche in the control non-diabetic population was 13.0 +/- 1.2 years and 13.4 +/- 1.2 years in the diabetics. The diabetic group was divided into those whose onset was before or after age 11 years (DM less than 11, DM greater than or equal to 11). The DM greater than or equal to 11 group had a mean menarchal age of 14.0 +/- 1.2 years and the DM less than 11 group, 13.1 +/- 1.2 (p less than 0.005). The DM greater than or equal to 11 group also differed significantly from the control group. The difference between the two groups suggests that the onset of diabetes near the onset of puberty may have a more disruptive effect on hypothalamic-pituitary-gonadal axis maturation that does the prepubertal onset of diabetes.
