Abstract

To describe the age at menarche and the prevalence of menstrual disturbances in an unselected group of women with insulin-dependent diabetes mellitus compared to controls, we identified all women having debut of diabetes mellitus before the age of 30 yr and living in the County of Funen, Denmark on July 1, 1987 and being between 18 and 49 yr old. The women received a structured questionnaire inquiring information concerning menstrual conditions. An age comparable group of nondiabetic women was used as controls; 245 (94%) diabetic women and 253 (88%) controls answered the questionnaire. Among women with debut of diabetes before the age of 10 yr, the age at menarche was delayed 1 yr when comparing to controls (P less than 0.0001). During the past 6 months before answering the questionnaire, 8.2% of the diabetic women and 2.8% of the controls had experienced episodes of secondary amenorrhea (P less than 0.01). Corresponding figures for oligomenorrhea were 10.6% and 4.8% (P less than 0.02), for polymenorrhea 7.3% and 5.2% (NS), and for all types of menstrual disturbances 21.6% and 10.8%, respectively (P less than 0.005). Episodes of secondary amenorrhea occurring more than 6 months before answering the questionnaire had been experienced by 10.7% of the diabetic population vs. 4.8% of the controls (P less than 0.05); corresponding figures for primary amenorrhea were 4.9% and 1.2%, respectively (P less than 0.05). We conclude that the age at menarche among women having developed insulin-dependent diabetes mellitus before the age of 10 yr was delayed by 1 yr when compared to controls. The overall prevalence of menstrual disturbances is increased in diabetic women compared to nondiabetic controls.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
