Abstract
Several studies have reported an association between age at menarche and the onset of type-1 diabetes mellitus (T1DM). This review compared the age at menarche in patients who had menarche after T1DM diagnosis with that of patients who were healthy and/or had menarche before T1DM diagnosis. Searches were conducted using four databases. The outcome was the age at menarche of patients who had menarche after T1DM diagnosis and patients who were healthy and/or had menarche before T1DM diagnosis. A qualitative analysis was performed using the JBI (Joanna Briggs Institute) Critical Appraisal. Quantitative analysis of the mean differences was performed using Revman 5.4 tool. A total of 1952 studies were obtained from the initial search. The final results were 13 articles that met the inclusion criteria for the qualitative assessment and eight for the quantitative assessment. Eight studies included 1030 patients who had menarche after being diagnosed with T1DM and 1282 patients who were healthy and/or had menarche before T1DM diagnosis. The meta-analysis showed a cumulative effect on a mean difference of 0.87 (95% CI: 0.75; 0.99, p-value < 0.00001), indicating a later age at menarche in patients who had menarche after T1DM diagnosis. The age at menarche was later in patients who had menarche after T1DM diagnosis compared to healthy subjects and those who had menarche beforehand.

Abstract
Diabetes affects men and women differently and the mistaken assumption of equality in its clinical expression can lead to errors and delays in the diagnostic process and the therapeutic strategy adopted. The objective is to show the gender differences that influence the approach to this pathology and what the role of the family doctor is in the monitoring of women with diabetes. It is a review of the impact of diabetes at different stages of a woman's life, how hormonal changes affect glycemic control, gestational diabetes, how diabetes affects the development of chronic complications in women and their consequences, the existing differences in the control of cardiovascular risk factors and the differential aspects by sex of the different families of drugs used in the treatment of diabetes.

Abstract
BACKGROUND Menstrual irregularities are present in >30% of women with type 1 diabetes mellitus (T1DM). These abnormalities will likely lead to reduced fertility and earlier menopause. T1DM management has changed over time, with even more emphasis on stringent levels of glycemic management. Thus, we investigated whether therapeutic T1DM changes have an influence on the proportion of menstrual disorders in women with T1DM. METHODS A meta-analysis was performed that included clinical trials in which menstrual abnormalities in women with T1DM were studied. The literature was checked for studies in which women with T1DM were compared with healthy, age-matched controls. Case-control, cohort, and cross-sectional studies were included. The primary endpoint was rate of menstrual dysfunction. RESULTS Menstrual dysfunction was higher in women with T1DM compared with controls (odds ratio 2.08, 95% confidence interval [CI] 1.43 to 3.03, p<0.001), even when sensitivity analysis was performed, considering only studies published after 2000. The age at menarche was higher for women with T1DM compared with controls (mean difference 0.53, 95% CI 0.32 to 0.74 years, p<0.001). The proportion of menstrual abnormalities in T1DM was inversely related to diabetes duration, but was unrelated to both body mass index and glycated hemoglobin. CONCLUSIONS The meta-analytic approach used confirmed the correlation between T1DM and menstrual irregularities. T1DM menstrual dysfunction seemed unrelated to change in therapeutic management across years, as well as to glycemic management and body weight. The underlying pathogenetic mechanisms are not fully understood.

Abstract
OBJECTIVES Disorders of pubertal development are enlisted as associated conditions in children and adolescents with type-1 diabetes (T1D). We conducted this study with objective (1) To estimate the median age at onset of puberty and luteinizing hormone (LH) and sex-steroid concentrations in Indian adolescents with T1D and (2) To assess the impact of puberty on glycemic control and insulin resistance (IR). METHODS This cross-sectional study included 399 children and youth aged 6-23 years with T1D. Demographic, anthropometric, biochemical and pelvic ultrasound data were collected using standard protocols. IR was calculated using estimated glucose disposal rate and puberty was assessed using Tanner staging. RESULTS Median age at onset of thelarche, pubarche and menarche were 11.3, 11.4 and 12.8 years in girls and that of gonadarche and pubarche were 10.6 and 12.7 years for boys. The mean LH and sex-steroid concentrations of subjects with T1D were similar to healthy subjects at each stage of puberty. The cut-offs of LH and sex-steroids derived from healthy Indian children yielded high sensitivity and specificity in determining pubertal onset. The prevalence of precocity, delayed puberty, ovarian cysts and polycystic ovaries was 0.9 , 5.1, 5.1 and 8.6 %, respectively. Glycaemic control and insulin sensitivity was poor in pubertal subjects. CONCLUSIONS The age at onset of puberty, LH, and sex-steroid concentrations in subjects with T1D were like otherwise healthy Indian children with poor glycemic control and IR in pubertal subjects. Although most complications of T1D are associated with poor glycemic control, pubertal disorders were significantly low despite the less-than-optimal glycemic control.

Abstract
PURPOSE Current knowledge about the ovarian reserve in patients with type 1 diabetes is inconsistent and based on studies with small sample size. This meta-analysis aimed to produce a comprehensive evaluation on the ovarian reserve of type 1 diabetes female patients and to analyze the associated factors with the ovarian reserve. METHODS Systematic searches were conducted for studies published from the inception to December 2021. Original human observational studies either with case-control, cross-sectional, or longitudinal design evaluating ovarian reserve markers between type 1 diabetes patients and healthy controls were included. Levels of anti-müllerian hormone (AMH), follicle-stimulating hormone (FSH), and estradiol (E2) were extracted. RESULTS It was indicated that women with type 1 diabetes were associated with decreased levels of AMH compared with healthy controls (weighted mean difference [WMD] -0.70 ng/ml, 95% confidence intervals [CI] -1.05 to -0.34 ng/ml, P = 0.0001). Subgroup analyses stratified by age showed that adult patients with type 1 diabetes were associated with decreased levels of AMH (WMD -0.70 ng/ml, 95% CI -1.06 to -0.34 ng/ml, P = 0.0001) and FSH (WMD -1.07 IU/L, 95% CI -1.75 to -0.39 IU/L, P = 0.002) compared with healthy controls. Meta-regression analysis showed no significant correlation between AMH, FSH, and clinical factors, while level of E2 was negatively correlated with daily insulin doses and glycosylated hemoglobin A1c (HbA1c) values. CONCLUSION According to this meta-analysis, type 1 diabetes might be associated with decreased AMH levels. Further studies using different markers and fertility outcomes focus on the ovarian reserve of women with type 1 diabetes are urgently needed.

Abstract
Menarche is delayed in patients with type 1 diabetic mellitus (T1DM) compared to non-diabetics. The purpose of this survey study was to define the age of onset of menarche in Japanese patients with T1DM, as well the secular trends in menarcheal age across the period of 1976-2020 and determine the effects of T1DM and disease management on that age. The study subjects (n = 155) were recruited from among Japanese T1DM patients who visited the outpatient clinic of the Department of Pediatrics, Osaka City University Hospital. The study subjects experienced menarche during 1976-2020. They were divided into the menarche-post-T1DM group (n = 117) and the menarche-pre-T1DM group (n = 38), in whom menarche occurred after or before the diagnosis of T1DM, respectively. The time of birth was also stratified into five decade/time bins extending from 1960s to 2000s. The subjects filled a questionnaire on menarche. Other clinical information was obtained from the medical records. The median age at menarche was 12.5 years (11.3-13.4) (25th-75th percentile) for the menarche-post-T1DM group and 11.8 years (10.9-13.0) for the menarche-pre-T1DM group (p = 0.024). Menarche occurred at a significantly younger age in recent years in the menarche-post-T1DM group (r = -0.209, p = 0.023), but no such trend was found in the control group. Analysis of data of subjects born after 1990 still showed significant delay associated with T1DM [post-T1DM group: 12.3 years (11.3-13.2), pre-T1DM group: 11.8 years (11.0-12.2), p = 0.045]. The results suggest that recent advances in insulin therapy seem to improve metabolism under T1DM but might have not enough impact on menarche in Japanese girls.

Abstract
PURPOSE OF REVIEW The purpose of this review is to summarize the current literature on the subject of linear growth in children and adolescents with or at risk for type 1 diabetes mellitus (T1DM). RECENT FINDINGS Poor glycemic control in T1DM is associated with growth hormone resistance, and improving glycemic control can improve linear growth. Newer reports suggest that the increasingly popular very low carbohydrate diets, may reduce linear growth velocity. SUMMARY Linear growth during childhood is a complex process regulated influenced by genetic, hormonal, nutritional and environmental factors. Linear growth may be impaired in children with T1DM, correlating with poor metabolic control; an extreme example is Mauriac syndrome. This decrement in linear growth appears to be driven in part by a reduction in growth hormone responsiveness, leading to low insulin-like growth factor-1 (IGF-1) levels. Improving glycemic control can lead to improved IGF-1 levels and linear growth. Other factors associated with poor linear growth in T1DM include celiac disease and dietary alterations, with early reports suggesting that very low carbohydrate diets, if not carefully managed, may increase risk of attenuated linear growth. This review examines the latest data regarding the associations between T1DM and linear growth in children.

Abstract
OBJECTIVE Evidence suggests that insulin deficiency and hyperglycemia may disrupt the female reproductive system's normal function, leading to delayed menarche and premature ovarian aging. We thus compared the length of the reproductive period of women with type 1 diabetes (T1D) to women without diabetes. METHODS Women with childhood-onset T1D (diagnosed in 1950-80) from the prospective Epidemiology of Diabetes Complications (EDC) study and nondiabetic women from the Pittsburgh site of the Study of Women's Health Across the Nation (SWAN) were studied. Exclusion criteria comprised not having reached natural menopause, hysterectomy/oophorectomy before menopause, and sex hormone therapy during the menopausal transition. Reproductive history was self-reported. The historical and Women's Ischemia Syndrome Evaluation hormonal algorithms were also used to assess menopause status. RESULTS Women in the T1D cohort (n = 105) were younger, more likely to be White, never smokers, with lower BMI and higher high-density lipoprotein cholesterol levels (all P values < 0.05) compared with women without diabetes (n = 178). After covariate adjustment, T1D women were also older at menarche (0.5-y delay, P = 0.002) but younger at natural menopause (-2.0 y, P < 0.0001). Women with T1D thus experienced 2.5 fewer reproductive years compared to those without diabetes (P < 0.0001). These findings were restricted to the subgroup of women who were diagnosed with T1D before reaching menarche (n = 80). CONCLUSION Women with T1D onset before menarche have a shorter reproductive period compared with nondiabetic women, exhibiting delayed menarche and earlier natural menopause. Factors that may be related to a shorter reproductive period in T1D should be investigated.

Abstract
Background Early onset of menarche is one of the most important factors for breast cancer and other associated health hazards. The aim of this study was to investigate the early age at menarche and its associated factors in school girls (age, 10–12 years) in Rajshahi District, Bangladesh. Methods Data was collected from Rajshahi District, Bangladesh, using multistage random sampling. Independent sample t test and binary logistic regression model were used in this study. A total number of 386 school girls aged 10–12 years were considered as a sample for this study. Results This study revealed that more than 48% girls already attained menarche within the age of 12 years, among them 25.6%, 41.0%, and 58.3% girls experienced menarche at the age of 10, 11, and 12 years, respectively. It was observed that the menarcheal girls were significantly taller (p < 0.01) and heavier (p < 0.01) than non-menarcheal girls. The menarcheal girls’ mothers were heavier (p < 0.01), shorter (p < 0.01), had more BMI (p < 0.01), reached menarche (p < 0.05) earlier than non-menarcheal girls’ mothers. Menarcheal girls had less number of siblings (p < 0.01) and lower order of birth (p < 0.05) than non-menarcheal girls. After controlling the effect of other factors, multiple logistic regression model demonstrated that obese girls were more likely to attain menarche than under- [AOR = 0.279, CI 95% 0.075–0.986; p < 0.05] and normal [AOR = 0.248, CI 95% 0.082–0.755; p < 0.05] weight girls. Urban school girls had more chance to get menarche than rural school girls at same age (AOR = 0.012, 95% CI 0.003–0.047; p < 0.01). Conclusions Therefore, modern lifestyle changes may have the important factors for early age at menarche of the studied girls in Bangladesh.

Abstract
AIM To test the hypothesis that delayed menarche is associated with an increased microvascular complication risk among women with Type 1 diabetes. METHODS We studied the female participants of an ongoing prospective study of childhood-onset Type 1 diabetes diagnosed during the period 1950-1980. Of 325 women, we included data from 315 who had reached menarche by the study baseline (1986-1988) and who self-reported their age at menarche. Both cross-sectional and prospective analyses over the 25-year follow-up were used to assess the relationship of age at menarche with the prevalence, incidence and cumulative incidence of microvascular complications, comprising overt nephropathy, proliferative retinopathy and confirmed distal symmetric polyneuropathy. RESULTS In cross-sectional analyses at baseline, the odds of overt nephropathy increased 1.24 times (P=0.02) with each annual increase in age at menarche, and 3.2 times (P=0.009) in those with delayed menarche compared with women with normal menarche onset, after adjustment. Similarly, the cumulative incidence of overt nephropathy increased 1.16 times (P=0.01) with each older year of menarche and women with delayed menarche were at twofold increased risk of overt nephropathy (hazard ratio 2.30, P=0.001) compared with women with normal menarche onset. However, age at menarche was not significantly associated with either proliferative retinopathy or confirmed distal symmetric polyneuropathy after adjusting for covariates. CONCLUSIONS Age at menarche was significantly associated with the prevalence and cumulative incidence of overt nephropathy, but not with proliferative retinopathy or confirmed distal symmetric polyneuropathy in Type 1 diabetes. Women with delayed menarche may therefore be targeted for early screening and timely interventions to prevent the development of nephropathy.

Cost-effectiveness analysis of biopsy strategies for endometrial cancer diagnosis in women with postmenopausal bleeding: Pipelle sampling curette versus dilatation & curettage. Gynecol Oncol 2018; 150:112-118. [PMID: 29747864 DOI: 10.1016/j.ygyno.2018.04.565] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2018] [Revised: 04/18/2018] [Accepted: 04/20/2018] [Indexed: 12/12/2022]
Abstract
BACKGROUND Endometrial sampling is widely used for accurate diagnosis of endometrial cancer (EC), which is the most common gynecologic cancer in US women. The objective of this study was to explore the cost-effectiveness of two endometrial sampling procedures for diagnosing EC: (1) Pipelle endometrial sampling (Pipelle), and (2) dilatation & curettage (D&C), while accounting for sampling procedure failure rates and diagnostic accuracy in women with postmenopausal bleeding (PMB). METHOD The decision analytic model was built to compare the cost-effectiveness of Pipelle and D&C strategies in a hypothetical cohort of PMB women. The analysis was performed from the perspective of a public healthcare payer (Medicare, US). We used 2017 Medicare reimbursement data for cost estimation. The effectiveness of these two diagnostic strategies was measured by analyzing the remaining life expectancy after EC diagnosis and subsequent treatment. RESULTS The base case analysis suggested that Pipelle was not only equally effective (32.11 vs. 32.11 years of life), but also less costly ($1897.80 vs. $2999.11) based on Medicare reimbursement when compared to D&C. In one-way sensitivity analyses and Monte Carlo probabilistic sensitivity analysis, the Pipelle remained the more cost-effective sampling strategy even after accounting for sampling failure rate associated with each sampling strategy. CONCLUSION The Pipelle is the more cost-effective sampling strategy compared to D&C for EC diagnosis in women with PMB. From the cost-effectiveness perspective, the higher sampling failure rate of Pipelle should not be regarded as a limitation in its clinical application.

Abstract
BACKGROUND Polycystic ovary syndrome (PCOS) is more frequently observed in type 1 diabetes mellitus (T1DM) adult women than in nondiabetic women. No such prevalence has yet been studied in adolescent girls with T1DM. AIM The aim of this study was to evaluate the prevalence of PCOS in adolescent girls with T1DM and to determine the clinical and hormonal features associated with the disorder. METHODS A cross-sectional study of 53 adolescent girls (gynecological age >2 years) referred for routine evaluation for T1DM was conducted. We diagnosed PCOS using the National Institutes of Health (NIH) and Rotterdam criteria. RESULTS 26.4 and 47.9% of adolescents had PCOS according to NIH (NIH-PCOS) and Rotterdam (Rotterdam-PCOS) criteria. 66.7% of NIH-PCOS adolescents had a complete phenotype associated with hyperandrogenism, oligomenorrhea, and polycystic ovarian morphology, unlike only 33.3% of the Rotterdam-PCOS adolescents. A family history of type 2 diabetes mellitus (T2DM) was more frequent in PCOS than in non-PCOS girls, whichever criteria were used. Late pubertal development and a T1DM diagnosis close to puberty were factors associated with NIH-PCOS. CONCLUSION Adolescents with T1DM had a high prevalence of PCOS. More differences between PCOS and non-PCOS patients were found using the NIH criteria, suggesting that clinical characteristics might be more accurate for diagnosing PCOS in girls with T1DM. A family history of T2DM is associated with a high risk of PCOS.

Abstract
AIM To identify reproductive disturbances among adolescent girls and young women with type 1 diabetes mellitus (T1DM) in Saudi Arabia.
METHODS This cross sectional study was conducted among 102 female with T1DM, (aged 13-29 years) who attended the Diabetes Clinic at Diabetes Treatment Center, Prince Sultan Military Medical City, Saudi Arabia between April 2015 to March 2016. Clinical history, anthropometric characteristics and reproductive disturbance were collected through a questionnaire.
RESULTS Of 102 patients included in this analysis, 26.5% (27/102) were reported that they experienced an irregular menses. Of these patients, when compared to whose diabetes was diagnosed before menarche (35.4%, 17/48), patients diagnosed with diabetes after menarche (18.5%, 10/54) showed significantly less irregular menses (difference 16.9%, P = 0.04). Similarly, compared to patients diagnosed with diabetes prior to menarche (mean age 12.9 years; n = 48), patients diagnosed with diabetes after menarche (mean age 12.26 years; n = 54) were found to have 0.64 years delay in the age of menarche (P = 0.04). Among the studied patients, 15.7% (16/102) had polycystic ovary syndrome (PCOS). Of these PCOS patients, 37.5% (6/16) had irregular menses, 6.3% (1/16) had Celiac disease, 37.5% (6/16) had Hashimoto thyroiditis and 18.7% (3/16) had acne.
CONCLUSION More than one fourth of the study population with T1DM experiencing an irregular menses. Adolescent girls and young women diagnosed with diabetes prior to menarche showed higher menstrual irregularity and a delay in the age of menarche.

Abstract
BACKGROUND This study aimed to investigate whether oestradiol differs between premenopausal women with and without type 1 diabetes and whether levels are associated with such factors as age, reproductive history or diabetes management. METHODS Oestradiol in premenopausal women with type 1 diabetes (n = 89; age = 18-50 years; duration = 13-18 years) and age-matched/race-matched controls without diabetes (n = 76) was collected during a cross-sectional ancillary study of the Wisconsin Diabetes Registry Study, a population-based incident cohort. Total and bioavailable oestradiol and sex hormone-binding globulin were compared using multivariable regression (e.g. adjusting for reproductive history). RESULTS Adjusted mean total and bioavailable oestradiol did not differ overall by diabetes status (p ≥ 0.74), while adjusted mean sex hormone-binding globulin was higher in type 1 diabetes women (p = 0.02). However, only in women with type 1 diabetes and not controls (interaction p = 0.0005) was total oestradiol positively associated with the duration of reproductive years with unsuppressed ovarian function (UnsuppOvFx = years since menarche minus years on hormonal contraceptives/pregnant/breastfeeding). When stratified into less than/equal to or greater than the median 9 years' duration of UnsuppOvFx, compared with controls, women with type 1 diabetes had significantly lower total oestradiol in the ≤9 years group [β = -43.2 pg mL-1 (-158.6 pmol L-1 ), p = 0.04] and significantly higher total oestradiol in the >9 years group [β = 53.9 pg mL-1 (197.9 pmol L-1 ), p = 0.04]. Results remained consistent during additional statistical adjustments and sensitivity analyses. CONCLUSIONS Compared with controls, women with type 1 diabetes may have lower oestradiol when they have a shorter duration of UnsuppOvFx and higher oestradiol when they have a longer duration of UnsuppOvFx. Given the potential effects of insulin on ovarian function, oestradiol production may vary across the lifespan for women with type 1 diabetes. Copyright © 2016 John Wiley & Sons, Ltd.

Abstract
BACKGROUND In T1DM, delayed pubertal development and reduced final height are associated with inadequate metabolic control. OBJECTIVE To assess whether T1DM affects pubertal growth spurt and whether metabolic control during puberty is gender-related. METHODS Using a large multicentre database, longitudinal data from 1294 patients were analysed. Inclusion criteria: complete records of height and HbA1c from the age of seven to 16 years. Exclusion criteria: other significant chronic diseases and medications, T1DM duration less than three months, and initial BMI < 3rd or >97th percentile. RESULTS Growth velocity (GV) was impaired with a significant reduction of peak GV by 1.2 cm in boys. HbA1c increase during male puberty was lower except for a period of 1.5 years. The highest HbA1c increase in boys coincided with maximum growth spurt. In girls, the highest HbA1c increase was observed during late puberty. Even though there is impaired GV, both sexes reach a height at 16 years of age which corresponds to the background population height. CONCLUSION Worsening of metabolic control is sex-discordant and associated with gender-specific alterations of GV. However, the vast majority of boys and girls with T1DM seems to reach normal height at the age of 16 years.

Abstract
Various data on type 1 diabetes mellitus (T1DM) have showed that the incidence of T1DM peaks at puberty. However, diabetes control and complications could be adversely affected by the physiological changes of puberty. In early years of insulin therapy, severe growth retardation with pubertal delay, like in Mauriac syndrome, have been reported. Insulin and leptin are metabolic factors, circulating in the periphery, which participate in the hypothalamic control of metabolism and reproduction. Insulin may be an important regulator of leptin in humans. Increased levels of advanced glycation end products suppress activation of the gonadotropin-releasing hormone (GnRH) pulse generator, resulting in pubertal delay. Glycemic control deteriorates during puberty as the lean body mass doubles mainly over a period of 25 years, which increases insulin requirement. There is also an increase in insulin resistance over the period of puberty. In normal individuals, fasting and postprandial insulin concentrations reach a peak in both sexes in mid to late puberty. Puberty, at all stages, has the worst insulin resistance. It has been observed that an excessive GH secretion in T1DM during puberty has significant effects on ketogenesis. Adolescent T1DM tends to decompensate very rapidly and develop ketoacidosis when the late night insulin dose is omitted. Adolescence is a critical developmental phase that presents unique challenges and opportunities to individuals with diabetes, their families and their healthcare providers.

Abstract
STUDY OBJECTIVE To investigate an association between pubertal development and timing of menarche with glycemic control, disease duration, and body mass index (BMI) in patients diagnosed with diabetes mellitus type 1 (DM1) before puberty. DESIGN Retrospective study. SETTING The study was performed at the diabetes outpatient clinic of Instituto de Puericultura e Pediatria Martagão Gesteira--IPPMG of the Federal University of Rio de Janeiro--UFRJ. PARTICIPANTS A total of 131 children, 61 girls and 70 boys, diagnosed with DM1 before puberty participated in the study. MAIN OUTCOME MEASURES The study investigated how age at puberty onset relates to mean glycated hemoglobin (HbA1c) before puberty, BMI percentile, and disease duration; how puberty duration relates to mean HbA1c before and during puberty and to disease duration; and how timing of menarche relates to mean HbA1c before puberty, BMI percentile, and disease duration. RESULTS Age at puberty onset was positively correlated with mean HbA1c before puberty (r = 0.204, R(2) = 0.042; P = .019) and disease duration (r = 0.451, R(2) = 0.203; P < .0001), and negatively correlated with BMI percentile (r = -0.289, R(2) = 0.084; P = .001). Timing of menarche was negatively correlated with BMI percentile (r = -0.556, R(2) = 0.310; P < .001). CONCLUSIONS Children with longer disease duration began puberty later than those diagnosed more recently. Girls in higher BMI percentiles reached menarche sooner.

Abstract
AIMS Determine the relationship between age at menarche, glycemic control and cardiovascular risk factors in patients with type 1 diabetes living in urban areas. METHODS This was a multicenter cross-sectional study conducted in 20 cities in four Brazilian geographic regions. Data were obtained from 1527 female patients, 59.3% Caucasians, aged 25.1 ± 10.6 years. Diabetes duration was 11.4 ± 8.1 years. Age at menarche was stratified in four groups: 8-11 (group 1, early menarche), 12 (group 2), 13 (group 3) and 14-18 years (group 4, late menarche). RESULTS The mean age at menarche was 12.7 ± 1.7 years without difference among geographical regions, economic status, level of care and ethnicity. BMI had an inverse correlation with age at menarche (r=-0.14, p<0.001). No significant difference was observed among the four groups for blood pressure, lipid profile and diabetes-related chronic complications. Logistic regression analysis showed that early age at menarche, 8-11 years (odds ratio (ORs) 1.77 [1.30-2.41], p<0.001) and duration of diabetes [ORs 1.01 (1.00-1.03), p=0.02], were related to greater risk of patients' overweight or obesity; adherence to diet [ORs 0.78 (0.60-0.93), p=0.01], physical activity [ORs 0.75 (0.94-0.94), p=0.01], and lower insulin dose (U/kg) [ORs 0.54 (0.59-0.90), p=0.001] were related to lower risk for overweight or obesity. CONCLUSIONS Early menarche occurred in 23.4% of women with type 1 diabetes living in Brazilian urban areas and was strongly associated with overweight/obesity in pubertal/adult life. Further studies are warranted to establish the relationship between early menarche, glycemic control and cardiovascular risk factors.

Abstract
BACKGROUND Individuals with type 1 diabetes may have low IGF-1, related to insulinopenia and insulin resistance. There are few longitudinal studies of IGF-1 levels to establish its pattern in type 1 diabetes with duration and age, and to examine whether IGF-1 tracks within individuals over time. We examine age and duration trends, and the relationship of IGF-1 to gender, glycaemic control, insulin level and other factors. METHODS Participants in the Wisconsin Diabetes Registry Study, an incident cohort study of type 1 diabetes diagnosed May 1987-April 1992, were followed for up to 18 years with IGF-1 samples up to age 45 for women and age 37 for men. RESULTS IGF-1 is lower with type 1 diabetes than in normative samples. Although, the pattern across age resembles that in normative samples with a peak in adolescence and slow decline after age 20, the adolescent peak is delayed for women with type 1 diabetes. There was low to moderate tracking of IGF-1 within an individual. Higher insulin dose was associated with higher IGF-1 as was puberty, and female gender. Adjusted for these factors, IGF-1 declined rapidly across early diabetes duration. Lower HbA1c was most strongly related to higher IGF-1 at Tanner stages 1 and 2. CONCLUSIONS IGF-1 is low in type 1 diabetes, with a delayed adolescent peak in women and is especially influenced by glycaemic control in early and pre-adolescence. High variability within an individual is likely a challenge in investigating associations between IGF-1 and long-term outcomes, and may explain contradictory findings.

Abstract
AIMS We estimated the number of live births worldwide and by IDF Region who developed hyperglycaemia in pregnancy in 2013, including total diabetes in pregnancy (known and previously undiagnosed diabetes) and gestational diabetes. METHODS Studies reporting prevalence of hyperglycaemia first-detected in pregnancy (formerly termed gestational diabetes) were identified using PubMed and through a review of cited literature. A simple scoring system was developed to characterise studies on diagnostic criteria, year study was conducted, study design, and representation. The highest scoring studies by country with sufficient detail on methodology for characterisation and reporting at least three age-groups were selected for inclusion. Forty-seven studies from 34 countries were used to calculate age-specific prevalence of hyperglycaemia first-detected in pregnancy in women 20-49 years. Adjustments were then made to account for heterogeneity in screening method and blood glucose diagnostic threshold in studies and also to align with recently published diagnostic criteria as defined by the WHO for hyperglycaemia first detected in pregnancy. Prevalence rates were applied to fertility and population estimates to determine regional and global prevalence of hyperglycaemia in pregnancy for 2013. An estimate of the proportion of cases of hyperglycaemia in pregnancy due to total diabetes in pregnancy was calculated using age- and sex-specific estimates of diabetes from the IDF Diabetes Atlas and applied to age-specific fertility rates. RESULTS The global prevalence of hyperglycaemia in pregnancy in women (20-49 years) is 16.9%, or 21.4 million live births in 2013. An estimated 16.0% of those cases may be due to total diabetes in pregnancy. The highest prevalence was found in the South-East Asia Region at 25.0% compared with 10.4% in the North America and Caribbean Region. More than 90% of cases of hyperglycaemia in pregnancy are estimated to occur in low- and middle-income countries. CONCLUSION These are the first global estimates of hyperglycaemia in pregnancy and conform to the new WHO recommendations regarding diagnosis and also include estimates of live births in women with known diabetes. They indicate the importance of the disease from a public health and maternal and child health perspective, particularly in developing countries.

Abstract
BACKGROUND It has been observed that menstrual characteristics are generally influenced by lifestyle, socio-cultural and biological factors. AIM The present study examines: (a) variation in menstrual characteristics between Type1 Diabetic females of rural and urban adolescents, i.e. the resident status; and (b) whether these characteristics can be predicted from various socio-economic, stress variables related to place of residence. SUBJECTS AND METHODS The sample of the present study constituted 103T1DM females from West Bengal, a State of India. These girls belong to a Bengali-speaking ethnic group. Data on socio-economic variables and menstrual characteristics were collected using pretested questionnaires. RESULTS Menstrual irregularity was common in our study participants, with age of menarche, but was not associated with current BMI, physical activity or insulin dose. CONCLUSIONS Our study displays that age at menarche is delayed in young women with T1DM compared to the concurrent overall mean age at menarche in the West Bengal population.

Abstract
BACKGROUND The functional reproductive alterations seen in women with type 1 diabetes (T1D) have changed as therapy has improved. Historically, patients with T1D and insufficient metabolic control exhibited a high prevalence of amenorrhea, hypogonadism and infertility. This paper reviews the impact of diabetes on the reproductive axis of female T1D patients treated with modern insulin therapy, with special attention to the mechanisms by which diabetes disrupts hypothalamic-pituitary-ovarian function, as documented mainly by animal model studies. METHODS A comprehensive MEDLINE search of articles published from 1966 to 2012 was performed. Animal model studies on experimental diabetes and human studies on T1D were examined and cross-referenced with terms that referred to different aspects of the gonadotropic axis, gonadotrophins and gonadal steroids. RESULTS Recent studies have shown that women with T1D still display delayed puberty and menarche, menstrual irregularities (especially oligomenorrhoea), mild hyperandrogenism, polycystic ovarian syndrome, fewer live born children and possibly earlier menopause. Animal models have helped us to decipher the underlying basis of these conditions and have highlighted the variable contributions of defective leptin, insulin and kisspeptin signalling to the mechanisms of perturbed reproduction in T1D. CONCLUSIONS Despite improvements in insulin therapy, T1D patients still suffer many reproductive problems that warrant specific diagnoses and therapeutic management. Similar to other states of metabolic stress, T1D represents a challenge to the correct functioning of the reproductive axis.

Abstract
Adolescence is a critical period for girls with type 1 diabetes mellitus (T1D). Reproductive issues, such as menstrual abnormalities, risk of an unplanned pregnancy, and contraception, should be addressed during this phase of life. This paper reviews several reproductive issues that are important in the care of adolescents, including pubertal development, menstrual abnormalities, ovulatory function, reproductive problems, the effects of hyperglycemia, contraception, and treatment of an unplanned pregnancy. A review of the literature was conducted. A MEDLINE search January 1966 to March 2011 was performed using the following MESH terms: puberty, menarche, ovary, polycystic ovary syndrome, menstruation, contraception, contraception-barrier, contraceptives-oral-hormonal, sex education, family planning services, and pregnancy in adolescence. This literature search was cross-referenced with an additional search on diabetes mellitus-type 1, diabetes complications, and pregnancy in diabetes. All published studies were searched regardless of the language of origin. Bibliographies were reviewed to extract additional relevant sources.

Abstract
OBJECTIVES To compare the pubertal development, the hormonal profiles and the prevalence of hirsutism and menstrual disorders in obese adolescent girls and adolescent girls with type 1 diabetes mellitus (T1DM). METHODS Data were collected from 96 obese adolescent girls and 78 adolescent girls with T1DM at Tanner stage IV or V, whose ages ranged between 11.9 and 17.9 years. RESULTS High prevalence of hirsutism and menstrual disorder was found in the obese adolescent girls (36.5 and 42% respectively) and the adolescent girls with T1DM (21 and 44% respectively). The obese girls were significantly younger at pubarche, thelarche and menarche than the girls with T1DM. Hirsutism in the obese girls and those with T1DM was associated with hyperandrogenaemia and a raised free androgen index (FAI). When the cause of the raised FAI was investigated in both the groups of girls with hirsutism, the raised FAI in the obese girls was due to low serum sex hormone-binding globulin (SHBG) levels. In contrast, the raised FAI of the girls with T1DM and hirsutism was due to hyperandrogenaemia. Menstrual disorders in the T1DM girls were associated also with hyperandrogenaemia unlike obese girls. CONCLUSIONS Hirsutism and menstrual disorders are common in obese adolescent girls and adolescent girls with T1DM. Although hyperandrogenaemia is present in both groups of girls, the androgenic profiles of the two groups differ. The hyperandrogenaemia in the obese girls is primarily due to their decreased serum SHBG levels, whereas the hyperandrogenaemia in the girls with T1DM is due to their increased androgen production.

Abstract
BACKGROUND Menarche delay has been reported in adolescent females with type 1 diabetes (T1DM), perhaps due to poor glycemic control. We sought to compare age at menarche between adolescent females with T1DM and national data, and to identify factors associated with delayed menarche and menstrual irregularity in T1DM. METHODS This was a cross-sectional study and females ages 12- 24 years (n = 228) with at least one menstrual period were recruited during their outpatient diabetes clinic appointment. The National Health and Nutrition Examination Survey (NHANES) 2001-2006 data (n = 3690) for females 12-24 years were used as a control group. RESULTS Age at menarche was later in adolescent females with T1DM diagnosed prior to menarche (12.81 +/- 0.09 years) (mean+/- SE) (n = 185) than for adolescent females diagnosed after menarche (12.17 0.19 years, p = 0.0015) (n = 43). Average age of menarche in NHANES was 12.27 +/- 0.038 years, which was significantly earlier than adolescent females with T1DM prior to menarche (p < 0.0001) and similar to adolescent females diagnosed after menarche (p = 0.77). Older age at menarche was negatively correlated with BMI z-score (r = -0.23 p = 0.0029) but not hemoglobin A1c (A1c) at menarche (r = 0.01, p = 0.91). Among 181 adolescent females who were at least 2 years post menarche, 63 (35%) reported usually or always irregular cycles. CONCLUSION Adolescent females with T1DM had a later onset of menarche than both adolescent females who developed T1DM after menarche and NHANES data. Menarche age was negatively associated with BMI z-score, but not A1c. Despite improved treatment in recent decades, menarche delay and high prevalence of menstrual irregularity is still observed among adolescent females with T1DM.

Abstract
INTRODUCTION Delayed pubertal maturation has been reported in girls with type 1 diabetes. OBJECTIVES To report the age of onset of puberty and menarche in girls with type 1 diabetes diagnosed before puberty. To investigate clinical factors affecting the occurrence of puberty and menarche in this population. PATIENTS AND METHODS A retrospective study of 38 girls with type 1 diabetes, all of them on intensive insulin therapy since diagnosis and followed up at our hospital until menarche. Age of onset of puberty and age of menarche were collected as dependent variables, and time since onset of diabetes, glycosylated hemoglobin levels, daily insulin requirements, and body mass index standard deviation score were collected as independent variables. Variables are expressed as mean ± standard deviation. Multivariate linear regression models tested the associations between dependent and independent variables. Statistical analysis was performed using SPSS software. RESULTS Thirty-eight girls were enrolled. Age of onset of puberty was 10.4 ± 1.1 years and age of menarche, 12.6 ± 1.0 years. Time since diabetes onset influenced age at onset of puberty (β = +0.12; p=0.047). A negative association was found between body mass index standard deviation score and age at menarche (β=-0.39; p=0.014). CONCLUSION Diabetes duration and body mass index were correlated with age of onset of puberty and age of menarche in girls with type 1 diabetes.

Abstract
OBJECTIVE We sought to examine whether age at menarche has changed over the past 4 decades by comparing age at menarche by year of diagnosis with type 1 diabetes. RESEARCH DESIGN AND METHODS This work consisted of a cross-sectional study of age at menarche in two cohorts: adolescents (ages 11-24 years, n = 228) and adults (ages 19-55 years, n = 290, enrolled in the Coronary Artery Calcification in Type 1 Diabetes study). RESULTS The adolescent cohort reported a younger age of menarche than the adult women with type 1 diabetes (12.69 ± 0.08 vs. 13.22 ± 0.12 years, mean ± SE, P < 0.001). Age at menarche was later in both adolescent girls and adult women with type 1 diabetes diagnosed before menarche (12.82 ± 1.16 and 13.7 ± 2.23 years) than for individuals diagnosed after menarche (12.12 ± 1.25 and 12.65 ± 1.38 years, P < 0.001 for both). Age at menarche was then examined by decade of type 1 diabetes diagnosis (1970-1979, 1980-1989, 1990-1999, and 2000-2009). Age at menarche significantly declined over the 4 decades (P = 0.0002). However, the delay in menarche among girls diagnosed with type 1 diabetes before menarche compared with those diagnosed after menarche was also significant across all decades (P < 0.0001) and did not change significantly over time (P = 0.41 for interaction of cohort and diagnosis premenarche). CONCLUSIONS Age at menarche has declined over the past 4 decades among girls with type 1 diabetes, but a delay in age at menarche remains among individuals diagnosed before menarche compared with individuals diagnosed after menarche.

Abstract
Diabetes mellitus type 1 might interfere with pubertal development. Particularly, long-term metabolic control and intensity of insulin treatment have been reported to contribute to a delay in pubertal onset. Data on somatic development in diabetic children are conflicting; therefore we studied bone age in 1788 children from Germany and Austria with type 1 diabetes. Bone age was retarded by -0.27 +/- 1.1 years in the whole group, but particularly in the adolescents at the end of puberty (>16 years; -0.76 +/- 1.29y). Bone age delay was more pronounced in boys, and in children with long-term median HbAlc levels of 7.5 - 9.0%. No associations were found with current HbAlc levels or the intensity of insulin treatment. Bone age determinations in diabetic children should only be performed when clinical signs of impaired somatic development are present. In addition, the potential influence of diabetes on bone development needs to be considered in the interpretation of carpograms.

Abstract
Age at menarche has been shown to be an important indicator for diseases such as breast cancer and ischaemic heart disease. The aim of the present study was to document secular trends in age at menarche and their association with anthropometric measures and socio-demographic factors in university students in Bangladesh. Data were collected from 995 students from Rajshahi University using a stratified sampling technique between July 2004 and May 2005. Trends in age at menarche were examined by linear regression analysis. Multiple regression analysis was used to assess the association of age at menarche with adult anthropometric measures and various socio-demographic factors. The mean and median age of menarche were 13.12+/-1.16 and 13.17 years, respectively, with an increasing tendency among birth-year cohorts from 1979 to 1986. Menarcheal age was negatively associated with BMI (p<0.01), but positively associated with height (p<0.05). Early menarche was especially pronounced among students from urban environments, Muslims and those with better educated mothers. Increasing age at menarche may be explained by improved nutritional status among Bangladeshi populations. Early menarche was associated with residence location at adolescence, religion and mother's education.

Abstract
STUDY OBJECTIVE The aim of the study was to investigate the age at menarche and menstrual irregularities in adolescents with type 1 diabetes. DESIGN This was an aged-matched, controlled study. SETTING The study was done in the diabetes center of a children's hospital in Athens and in high schools in major regions of central Greece. PARTICIPANTS The study involved two groups: a group of 100 female adolescents, 12 to 18 years of age, with type 1 diabetes; and a control group of 225 healthy adolescents, matched for age. MAIN OUTCOME MEASURES The relationship between age at menarche and menstrual irregularities was studied. RESULTS The mean age at menarche differed significantly in the two groups (P=0.000). In particular, the mean age at menarche in the study group was 12.2 years (+/- 1.4) and in the control group it was 11.7 years old (+/- 1.2). The mean age of menarche was older in the subgroup of adolescents who had received a diagnosis of diabetes before the age of 10 than it was in those diagnosed after the age of 10. CONCLUSIONS Menarche was observed to be delayed in adolescents with type 1 diabetes who had been diagnosed before the age of 10 in comparison with those diagnosed after the age of 10. Menstrual irregularities were found to be more common in adolescents with type 1 diabetes than in healthy ones.

Nutr Metab Cardiovasc Dis 2009; 19:35-38. [PMID: 18554878 DOI: 10.1016/j.numecd.2007.12.002] [Citation(s) in RCA: 11] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/06/2007] [Revised: 09/21/2007] [Accepted: 12/02/2007] [Indexed: 11/30/2022]
Abstract
BACKGROUND AND AIM Previous studies on menarcheal age (MA) in type 1 diabetes mellitus (T1DM) have shown conflicting results about the effects of DM, but most lack a control group. The present study design is peculiar in that it covers a study population of 73 intensively treated menarcheal adolescents with premenarcheal onset of T1DM (Group A), whose MA was compared with that recorded in three control populations: the first one consisting of 280 healthy adolescents, the second one consisting of 20 T1DM adolescents with postmenarcheal DM onset (Group B) and the third one represented by the respective mothers. METHODS AND RESULTS MA of Group A patients was significantly delayed when compared with the respective mothers, healthy controls and Group B patients. By contrast MA of Group B girls was superimposable to the one of both their respective mothers and healthy controls. In Group A MA was strongly related (p<0.0005) to HbA1c at the time of menarche and to average HbA1c concentrations during the last years before menarche. In Group A no relationship between patients' and mothers' MAs was found, whilst such a correlation was significant in Group B. CONCLUSIONS (a) MA is significantly delayed in girls with premenarcheal presentation of T1DM, even if intensively treated; (b) menarcheal retardation is more severe in the patients with suboptimal metabolic control at the time of menarche; and (c) MA in premenarcheal presenting T1DM is irrespective of maternal MA, age and HbA1c concentrations at DM presentation, body mass index and daily insulin dose at menarche.

Abstract
BACKGROUND Findings have been inconsistent regarding the effect of T1DM (type 1 diabetes) on age at menarche. OBJECTIVE The purpose was to investigate in young German women with T1DM menarcheal age and factors potentially affecting menarche, including glycemic control, BMI (body mass index), relative T1DM duration (proportion of life with diabetes), insulin dose, and insulin therapy intensity. Initiated in 1990, the DPV program is an ongoing, prospective long-term longitudinal follow-up study to benchmark the quality of care provided to pediatric and, more recently, adult diabetes patients. Two hundered two German diabetes centers participated in nationwide data collection. Based on ethnicity and the availability of menarche and T1DM onset data as the main inclusion criteria, 643 young German women were selected from 11,629 female T1DM patients aged <20 years, recruited by referral, clinic or hospital ascertainment, or self report. Mean age at menarche (+/-SD) was 13.22 +/- 1.31 years, representing a delay of 0.52 years (p < 0.001) relative to the general population. Significant delay (p < 0.05) was also found for relative T1DM duration, BMI SD score, insulin dose, and HbA1c level, with a 1% increase in HbA1c resulting in a delay in menarche by 0.07 years. CONCLUSIONS Age at menarche is delayed in type 1 diabetes mellitus. The delay increases with relative T1DM duration and poor quality of glycemic control.

Abstract
OBJECTIVE Insulin downregulates hepatic production of sex hormone-binding globulin (SHBG), which in turn influences sex hormone bioavailability. The effects of childhood-onset diabetes and insulin resistance in nondiabetic individuals on SHBG and testosterone in children and young adults are poorly understood. RESEARCH DESIGN AND METHODS Individuals with diabetes diagnosed at <18 years of age (n = 48) and their siblings without diabetes (n = 47) were recruited for the Chicago Childhood Diabetes Registry Family Study. SHBG and total and free testosterone were measured. Participants ranged in age from 10 to 32 years; 39% were non-Hispanic white. The majority of individuals with diabetes had the classic type 1 phenotype (75%), while the remainder exhibited features of type 2 or mixed diabetes; 96% were treated with insulin. RESULTS SHBG and total testosterone were higher in male subjects with diabetes compared with those in male siblings. Elevated SHBG was associated with the absence of endogenous insulin independent of sex; elevated total testosterone was similarly associated with the absence of C-peptide for male subjects only. Diabetes type and treatment were unrelated. In those without diabetes, greater insulin resistance had a small, nonsignificant association with lower SHBG and higher free testosterone. CONCLUSIONS SHBG and total testosterone appear to be higher in male children and young adults with diabetes compared with nondiabetic male siblings, which is apparently related to the absence of endogenous insulin. This may have implications for sex hormone-dependent processes across the lifespan in male individuals diagnosed with diabetes as children.

Abstract
OBJECTIVE To investigate the effect of type 1 diabetes on pubertal onset and development, and to identify factors potentially affecting puberty, including glycemic control, relative diabetes duration, body mass index standard delta score (BMI SDS), insulin dose, and intensity of insulin therapy. RESEARCH DESIGN AND METHODS Initiated in 1990, the Diabetes-Patienten-Verlaufsdaten (DPV) is an ongoing, prospective longitudinal follow-up program to benchmark the quality of diabetes care provided to, predominantly, pediatric patients. Data collection for this non-interventional audit was carried out at 202 German diabetes treatment centers. Patient recruitment was done by referral, clinic/hospital ascertainment, or self-report. Data were analyzed for subcohorts of 1218-2409 boys and 579-2640 girls from a cohort of 24 385 pediatric type 1 diabetic patients. Selection was based on ethnicity and availability of data on Tanner stage 2, or higher, of genital and pubic hair development (boys) or breast and pubic hair development, and menarche (girls). RESULTS Boys showed significant (P<0.05) delay (years) in mean ages at onset of genital development (12.0 (+/-0.9) years) and pubarche (12.2 (+/-0.4) years). In girls, mean ages at thelarche (11.4 (+/-0.5) years), pubarche (11.5 (+/-0.1) years), and menarche (13.2 (+/-0.5) years) were significantly delayed compared with the general population. Sexual maturity (Tanner stage 5) was not delayed in either sex. Elevated glycohemoglobin and decreased BMI SDS were associated with significantly delayed pubertal onset, whereas relative diabetes duration and insulin dose were not. CONCLUSIONS Pubertal onset, but not sexual maturity, is delayed in children with type 1 diabetes. Delay increases with higher glycohemoglobin and lower BMI SDS.

Abstract
OBJECTIVE Children with type 1 diabetes (T1DM) are at increased risk for celiac disease (CD); however, the benefits of screening for IgA tissue transglutaminase autoantibodies (TG), a marker for CD, are unclear. STUDY DESIGN We compared 71 screening-identified TG+ with 63 matched TG- children with TIDM. Growth, bone density, and diabetes control measures were obtained. RESULTS The group was 10 +/- 3 years of age, 46% male, with TIDM for 4 +/- 3 years. Z scores for weight (0.3 +/- 1 vs 0.7 +/- 0.8, P = .024), body mass index (BMI) (0.3 +/- 0.9 vs 0.8 +/- -0.8, P = .005), and midarm circumference (0.3 +/- 1.1 vs 0.6 +/- 0.9, P = .031) were lower in the TG+ group. Bone mineral density and diabetes control measures were similar. When limiting the analysis to the 35 TG+ subjects with biopsy changes of CD, the BMI Z score was lower than the control group (0.4 +/- 0.9 vs 0.7 +/- 0.7, P = .05). CONCLUSIONS In children with TIDM, screening-identified evidence of CD is associated with altered body composition, but not bone mineral density or diabetes control. Further study is needed to determine the benefit of early diagnosis and treatment of CD in TIDM children.

Abstract
CONTEXT At present, women with type 1 diabetes (DM1) are being treated with supraphysiological doses of exogenous insulin with the aim of providing a strict metabolic control, thereby avoiding the long-term complications of this disease. We hypothesized that PCOS would be especially prevalent in DM1, as might happen in any condition in which the ovary and the adrenals are exposed to excessive insulin concentrations. As will be seen in the present review, androgen excess and PCOS are very frequent complaints in women with DM1, yet nowadays hyperandrogenism is seldom diagnosed in these patients. EVIDENCE ACQUISITION We conducted a systematic review of all the published studies addressing hyperandrogenic symptoms in women with DM1, identified through the Entrez-PubMed search engine, followed by a comprehensive review of the pathophysiology and clinical and laboratory features of PCOS in women with DM1. EVIDENCE SYNTHESIS The prevalence of PCOS in adult women with DM1 is 12-18, 40, and 31% using National Institute for Child Health and Human Development, Rotterdam, and Androgen Excess Society criteria, respectively. Mild hirsutism and biochemical hyperandrogenism are present in 30 and 20% of the patients, respectively. In addition, menstrual abnormalities are observed in 20% of adult women with DM1, and a prevalence of 50% of polycystic ovarian morphology is reported. CONCLUSIONS Physicians treating women with DM1 should be aware of the risk of hyperandrogenism in them and should include evaluation of hirsutism, menstrual abnormalities, and biochemical hyperandrogenism in their routine examinations. Future studies are needed to determine the best preventive and therapeutic options for the hyperandrogenism of these patients.
