Abstract
Background More remains to be known about polycystic ovary syndrome (PCOS) among overweight/obese adolescents across different ethnicities especially in regards to mental illness as an associated comorbidity. Objective To determine the prevalence of PCOS among overweight and obese adolescents and to evaluate known risk factors for PCOS in a diverse population. Methods Charts of patients at an Adolescent Clinic between April 1, 2016 and July 30, 2018 were filtered using: obese, overweight and body mass index (BMI) >85%. Charts were reviewed to identify the presence of PCOS using National Institutes of Health (NIH) criteria, race/ethnicity and known risk factors for PCOS [lipid, BMI, glycated hemoglobin (HA1c), blood pressure (BP)] and mental health conditions associated with PCOS (anxiety/depression and self-harm/suicidal ideation). Results Patients with PCOS were more likely to have elevated lipids (19.6% vs. 9.9%, p = 0.05), be obese (67.4% vs. 50.9%, p = 0.03), and have acanthosis nigricans (68.9% vs. 28.2%, p =< 0.001). PCOS was more common among non-Hispanic patients (77.9%) vs. Hispanic patients (57.8%). There was no difference in the prevalence of depression/anxiety (37% vs. 33%, respectively, p = 0.590) or self - harm/suicidal ideation (17% vs. 17%, p = 0.96) in patients with and without PCOS. In a logistic regression model, after adjusting for all demographics and clinical features, ethnicity, acanthosis nigricans and BMI were significant risk factors for PCOS. Conclusion Patients with PCOS are more likely to be obese, hyperlipidemic, have acanthosis nigricans and be of non-Hispanic ethnicity. However, there was no difference in the prevalence of depression/anxiety and self-harm/suicidal ideation among adolescents with or without PCOS.

Ethnicity, obesity and the prevalence of impaired glucose tolerance and type 2 diabetes in PCOS: a systematic review and meta-regression. Hum Reprod Update 2019; 24:455-467. [PMID: 29590375 DOI: 10.1093/humupd/dmy007] [Citation(s) in RCA: 203] [Impact Index Per Article: 40.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2017] [Accepted: 03/12/2018] [Indexed: 12/23/2022] Open
Abstract
BACKGROUND Our prior meta-analyses demonstrated an increased prevalence of impaired glucose tolerance (IGT) and type 2 diabetes mellitus (T2DM) with polycystic ovary syndrome (PCOS), but with substantial clinical heterogeneity. OBJECTIVE AND RATIONALE We aimed to update our previous review to quantify the prevalence of IGT and T2DM in PCOS with only quality studies (good and fair quality). We also aimed to examine the contribution of parameters including ethnicity, obesity and method of diagnosing T2DM in explaining the observed heterogeneity in IGT and T2DM prevalence in PCOS. SEARCH METHODS We conducted a literature search (MEDLINE, CINAHL, EMBASE, clinical trial registries and hand-searching) up to June 2016 to identify studies reporting the prevalence of dysglycemia (IGT and T2DM) in women with and without PCOS. We included studies where women with PCOS (defined according to original National Institute of Health) were compared to women without PCOS for the end-points of the prevalence of IGT or T2DM. We excluded case reports, case series, editorials, and narrative reviews. Studies where PCOS was diagnosed by self-report, or where IGT or T2DM were measured by fasting glucose, only were excluded. We assessed the methodological quality of the included studies using a priori criteria based on the Newcastle-Ottawa Scaling (NOS) for non-randomized studies. Data are presented as odds ratio (OR) (95% CI) with random-effects meta-analysis by Mantel-Haenszel methods. We assessed the contribution of demographic and clinical factors to heterogeneity using subgroup and meta-regression analysis. OUTCOMES We reviewed 4530 studies and included 40 eligible studies in the final analysis. On meta-analysis of quality studies, women with PCOS had an increased prevalence of IGT (OR = 3.26, 95% CI: 2.17-4.90) and T2DM (OR = 2.87, 95% CI: 1.44-5.72), which differed by ethnicity (for IGT, Asia: 5-fold, the Americas: 4-fold and Europe: 3-fold), was higher with obesity, and doubled among studies using self-report or administrative data for diagnosing diabetes. The ethnicity-related difference retained its significance for Asia and Europe in BMI-matched subgroups. Clear contributors to heterogeneity did not emerge in meta-regression. WIDER IMPLICATIONS Our findings underscore the importance of PCOS as a cause of dysglycemia with a higher prevalence of IGT and T2DM. They support the relevance of ethnicity and obesity and emphasize the need for accurate diagnostic methods for diabetes. PROSPERO REGISTRATION NUMBER CRD42017056524.

Abstract
STUDY OBJECTIVE We evaluated the plasma visfatin levels in hirsute female adolescents with polycystic ovary syndrome. DESIGN, SETTING, AND PARTICIPANTS This prospective case-control study included 87 female patients who were seen in our adolescence department. Demographic characteristics and hormonal and biochemical parameters were evaluated between patients with and without polycystic ovary syndrome. Next, we divided the patients with polycystic ovary syndrome into the following subgroups: overweight or obese (body mass index [BMI] ≥ 25 kg/m(2)) vs normal weight (BMI < 25 kg/m(2)) and hirsute vs nonhirsute. RESULTS There were statistically significant differences in the BMI, serum androgen levels, homeostasis model assessment-insulin resistance (HOMA-IR) levels, and insulin levels between patients with and without polycystic ovary syndrome (P < .05). The mean visfatin levels showed no statistically significant difference between these 2 groups (P > .05). The serum visfatin levels were similar between the 2 subgroups classified by BMI (P > .05). However, there were statistically significant differences in the total and free testosterone levels, 17-hydroxylase progesterone level, HOMA-IR level, and visfatin level between the 2 subgroups classified by hirsutism (P < .05). The plasma visfatin level was higher in hirsute PCOS than in nonhirsute PCOS patients. CONCLUSION Significantly higher visfatin levels were found in hirsute than in nonhirsute adolescents with PCOS. According to these results, plasma visfatin levels may be a useful marker in hirsute adolescents with PCOS.

Peripheral insulin resistance in obese girls with hyperandrogenism is related to oxidative phosphorylation and elevated serum free fatty acids. Am J Physiol Endocrinol Metab 2015; 308:E726-33. [PMID: 25714677 PMCID: PMC4420897 DOI: 10.1152/ajpendo.00619.2014] [Citation(s) in RCA: 37] [Impact Index Per Article: 4.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/31/2014] [Accepted: 02/19/2015] [Indexed: 12/25/2022]
Abstract
Hyperandrogenic syndrome (HAS) is associated with insulin resistance (IR) and type 2 diabetes. Muscle IR in type 2 diabetes is linked with defects in mitochondrial oxidative capacity. In vivo muscle mitochondrial function has not been studied in HAS, especially in youth, who are early in the disease process. Our goal was to measure muscle mitochondrial oxidative function and peripheral IR in obese youth with HAS. Obese girls without HAS [n = 22, age 15(13,17) yr, BMI Z-score 2.05 ± 0.37] and with HAS [n = 35, age 15(14,16) yr, BMI Z-score 2.18 ± 0.30] were enrolled. Mitochondrial function was assessed with (31)phosphorus MR spectroscopy before, during, and after near-maximal isometric calf exercise, and peripheral IR was assessed with an 80 mU·m(-2)·min(-1) hyperinsulinemic euglycemic clamp. Girls with HAS had higher androgens [free androgen index 7.9(6.6,15.5) vs. 3.5(3.0,4.0), P < 0.01] and more IR [glucose infusion rate 9.4(7.0, 12,2) vs. 14.5(13.2,15.8) mg·kg lean(-1)·min(-1), P < 0.01]. HAS girls also had increased markers of inflammation including CRP, platelets, and white blood cell count and higher serum free fatty acids during hyperinsulinemia. Mitochondrial oxidative phosphorylation was lower in HAS [0.11(0.06,0.19) vs. 0.18(0.12,0.23) mmol/s, P < 0.05], although other spectroscopy markers of mitochondrial function were similar between groups. In multivariate analysis of the entire cohort, IR related to androgens, oxidative phosphorylation, and free fatty acid concentrations during hyperinsulinemia. These relationships were present in just the HAS cohort as well. Obese girls with HAS have significant peripheral IR, which is related to elevated androgens and free fatty acids and decreased mitochondrial oxidative phosphorylation. These may provide future options as targets for therapeutic intervention.

Abstract
PURPOSE Screening for impaired glucose tolerance (IGT) is recommended for adolescents with polycystic ovary syndrome (PCOS) with oral glucose tolerance test (OGTT). Whether glycated hemoglobin (HbA1c) can be used for screening in this patient population is unknown. We sought to determine the utility of HbA1c and 2-hour OGTT for diagnosing dysglycemia in adolescents with PCOS. METHODS This was a retrospective cohort study of 68 adolescents with PCOS seen in the Boston Children's Hospital Division of Adolescent Medicine between 2008 and 2011 and not known to have diabetes. Prevalence of dysglycemia (impaired fasting glucose, IGT, increased risk for diabetes, or diabetes mellitus as diagnosed by fasting plasma glucose, 2-hour OGTT, and/or HbA1c) and sensitivity and specificity of HbA1c for diagnosing dysglycemia compared with OGTT were assessed. RESULTS Twenty-four participants had abnormal glucose testing, including one participant (1.5%) who met criteria for diabetes mellitus and 23 participants (34%) who met criteria for impaired fasting glucose/IGT/prediabetes. More patients were identified as having dysglycemia by HbA1c than OGTT. Compared with OGTT, HbA1c had a sensitivity of 60% and a specificity of 69% for diagnosing dysglycemia. CONCLUSIONS In adolescents with PCOS, HbA1c had moderate sensitivity and specificity for detecting dysglycemia compared with OGTT. Clinicians should be aware that both tests have benefits and limitations, and the optimal test for follow-up requires further study.

Abstract
Abnormal glucose metabolism is associated with obesity, insulin resistance (IR), and Type 2 diabetes mellitus. The purposes of this study were to describe anthropometric and laboratory markers of adolescents, examine correlates of IR, and test ability of anthropometric and laboratory markers to predict risk of exhibiting IR. A total of 150 early adolescents participated. Participants with obesity had increased IR, high-sensitivity C-reactive protein, triglycerides, and blood pressure. Waist circumference and triglycerides were predictive of IR. Multiple risk factors compound and lead to long-term health consequences among youth. Nurses can evaluate these factors to identify IR.

Abstract
The aim of this study was to compare polysomnographic variables of obese adolescents with polycystic ovarian syndrome (PCOS) to those of healthy controls and to analyse whether polysomnographic variables correlate to parameters of body weight/body composition, to serum androgens and to parameters of glucose metabolism. Thirty-one obese adolescents with PCOS (15.0 years ± 1.0, body mass index 32.7 kg per m(2) ± 6.2) and 19 healthy obese adolescents without PCOS (15.2 years ± 1.1, body mass index 32.4 kg per m(2) ± 4.0) underwent polysomnography to compare apnoea index, hypopnoea index, apnoea-hypopnoea index, the absolute number of obstructive apnoeas, percentage sleep Stages 1, 2, 3 and 4 of non-rapid eye movement (NREM) sleep, percentage of REM sleep, TIB, total sleep time (TST), sleep-onset latency, total wake time (TWT), wakefulness after sleep onset (WASO) and sleep efficiency. Furthermore, we correlated polysomnographic variables to parameters of body weight/body composition, to serum androgens and to parameters of glucose metabolism. We found no differences between the two groups concerning the respiratory indices, percentage sleep Stages 2, 3 and 4 of NREM sleep, TIB and sleep-onset latency. The girls with PCOS differed significantly from the controls regarding TST, WASO, TWT, sleep efficiency, percentage Stage 1 of NREM sleep and percentage of REM sleep. We found a weak significant correlation between insulin resistance and apnoea index and between insulin resistance and apnoea-hypopnoea index. Concerning the respiratory variables, adolescents with PCOS do not seem to differ from healthy controls; however, there seem to be differences concerning sleep architecture.

Abstract
BACKGROUND Adults with polycystic ovary syndrome (PCOS) can have multiple metabolic abnormalities. However, studies in the adolescent population are still limited and these results seem to vary widely. This study was to investigate the metabolic abnormalities in adolescents with PCOS in South China and the potential risk factors contributed to these health risks. METHODS Anthropometric measurements and biochemical parameters were evaluated in 128 adolescents with PCOS and their age- and BMI-matched controls. RESULTS The prevalence of pre-diabetes, insulin resistance, hyperinsulinemia, dyslipidemia and metabolic syndrome in adolescents with PCOS was 11.7%, 46.9%, 29.7%, 22.7% and 4.7%, respectively. 16.3%, 74.4%, 67.4%, 39.5% and 14% of the PCOS subjects with BMI > 85th had pre-diabetes, insulin resistance, hyperinsulinemia, dyslipidemia and metabolic syndrome, whereas 9.4%, 32.9%, 10.6%, 14.1% and 0% of the PCOS subjects with BMI < 85th had such disturbances. CONCLUSIONS Adolescents with PCOS in South China had more metabolic abnormalities than their age- and BMI-matched non-PCOS counterparts. Obesity could worsen insulin resistance, hyperinsulinemia and metabolic syndrome in PCOS adolescents.

Abstract
The definition of polycystic ovary syndrome in very young girls is complicated by the fact that many features typical of the syndrome can also be seen as physiological stages in the maturation of the hypothalamus-pituitary-ovarian axis. The role of reduced insulin sensitivity in the pathogenesis and evolution of the disorder has gained more importance over recent years: both elevated androgen levels and being overweight may influence the impairment of glucose metabolism. Our study focused on 250 girls in the first 8 years of gynecological age. We analyzed the prevalence of different phenotypes according to the Rotterdam criteria and the impact of higher BMI on androgen levels and on fasting screening markers of glucose metabolism. In a smaller sample, we performed a more detailed evaluation of the glucose metabolism parameters; our findings indicated that in this age group, being overweight plays a major role in the deterioration of the clinical picture.
