Abstract
CONTEXT Controversial results have emerged regarding whether PCOS is protective or increases the risk of bone frailty. OBJECTIVE This study investigated whether the PCOS condition affects bone parameters of premenopausal women. This is an update for a previous meta-analysis published in 2019. DATA SOURCES We searched MEDLINE and Embase. STUDY SELECTION Studies were considered eligible for the update if published in English between the 1st of October 2018 and the 31st of December 2023. The diagnosis of PCOS should be based on NIH criteria, the Rotterdam Consensus, AE-PCOS society criteria, or ICD codes in women over 18 years old. Only records with the Newcastle-Ottawa Scale > 6 were selected for data extraction. DATA EXTRACTION Data were extracted by two independent reviewers. DATA SYNTHESIS We identified 31 studies that met the inclusion criteria for qualitative analysis from 3322 studies in the whole period (1990-2023). Overall, cross-sectional studies included 1822 individuals with PCOS and 1374 controls, while cohort studies incorporated 30305 women with PCOS and 101907 controls. Contrasting profiles emerged after stratification using a BMI cutoff of 27 kg/m2. Individuals with PCOS and a BMI <27 kg/m2 exhibited lower vertebral and non-vertebral bone density, reduced bone turnover marker (osteocalcin), and increased bone resorption marker (CTX) levels. Conversely, individuals with PCOS and a BMI >27 kg/m2 exhibited increased vertebral and non-vertebral BMD, with no significant changes in bone formation and resorption markers (except osteocalcin). CONCLUSIONS The findings of this study alert for a low bone mass, low bone formation, and increased bone resorption PCOS with a BMI <27 kg/m2.

Abstract
Background Whether the endocrine aberrations caused by polycystic ovary syndrome (PCOS) might influence bone density in women of reproductive age is controversial. Objectives The present study aimed to compare PCOS women to a control group matched in terms of age and body mass index (BMI) regarding bone indices and to clarify the potential relationship between their hormonal changes and bone density. Methods This case-control study consisted of 61 PCOS patients, and 35 women with normal ovulatory function served as controls. Bone parameters, including bone mineral content (BMC) and bone mineral density (BMD) in addition to T- and Z-scores, were measured at the lumbar vertebrae, neck of the left femur, hip, and distal part of the radial bone, using dual-energy X-ray absorptiometry. Blood samples were taken to be tested for biochemical parameters and serum concentrations of insulin, osteocalcin, parathyroid hormone (PTH), vitamin D, follicle-stimulating hormone (FSH), luteinizing hormone (LH), total testosterone, dehydroepiandrosterone sulfate (DHEAS), and estradiol were measured. Insulin resistance was evaluated through the homeostatic model assessment of insulin resistance (HOMA-IR). Results The results revealed greater levels of HOMA-IR and total testosterone in PCOS women than in controls. Nevertheless, the two groups were comparable in terms of bone parameters. In the control group, BMI was the only determinant of bone density at most of the skeletal sites. Nonetheless, BMI and HOMA-IR were independently and positively associated with bone indices at the femoral neck (FN) and total hip in the PCOS group. Parathyroid hormone and vitamin D concentrations were not different in the two groups. However, phosphate levels were higher in PCOS patients (P = 0.025). Osteocalcin was inversely correlated to BMI, and both groups had a negative correlation between DHEAS and PTH. Serum phosphate was inversely and independently associated with estrogen in the PCOS group (r = -0.377, P = 0.004). Conclusions Body mass index and HOMA-IR were independent and positive determinants of FN and total hip bone density in the PCOS subjects. Nonetheless, in the non-PCOS women, BMI was the only independent determinant of bone density at most of the skeletal sites. Additionally, osteocalcin was inversely correlated with BMI in both groups.

Genetic risk for the polycystic ovary syndrome, bone mineral density and fractures in women and men: A UK Biobank Mendelian randomisation study. Bone 2022; 155:116285. [PMID: 34902614 DOI: 10.1016/j.bone.2021.116285] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/11/2021] [Revised: 11/13/2021] [Accepted: 12/01/2021] [Indexed: 11/02/2022]
Abstract
INTRODUCTION There is conflicting data on the effect of polycystic ovary syndrome (PCOS) on bone mineral density (BMD) and fracture risk. Recent genetic data suggest that men may also carry genetic risk factors for PCOS; the associations of these factors with parameters of bone health remains unknown. We aimed to investigate if the genetic risk of PCOS is associated with BMD and fracture risk in women and men in the UK Biobank dataset. METHODS We used Mendelian randomisation (MR) analysis to test the association of genetic risk of excess testosterone in PCOS with BMD and fractures in the UK biobank study. The MR analysis was performed using linear regression analysis with the weighted genetic risk score (wGRS) as an independent variable adjusting for age, BMI and population eigenvectors. The horizontal pleiotropy in the MR analysis was tested using MR-Egger regression analysis. RESULTS The study consisted of 221,086 Caucasian women (mean age ± SD: 56.7 ± 7.9 years, mean body mass index [BMI] ± SD: 27.0 ± 5.1 kg/m2, mean BMD ± SD: 0.50 ± 0.11 g/cm2) and 187,816 Caucasian men (mean age ± SD: 57.1 ± 8.1 years, mean BMI ± SD: 27.7 ± 4.1 kg/m2 and mean BMD ± SD: 0.56 ± 0.12 g/cm2). Women and men self-reported 24,797 (11%) and 17,076 (10%) fractures over the last 5 years, respectively. The MR analysis showed that one SD increase in the wGRS for clinical or biochemical hyperandrogenism in PCOS was associated with significantly higher heel BMD (Beta = 0.0007 [±0.0002], P-value = 0.001) and a significantly reduced risk of fractures (OR = 0.97, P-value = 0.003) in women. A similar wGRS in men was not associated with BMD or risk of fractures. CONCLUSION In this study, we showed that the excess genetic risk for hyperandrogenism in women with PCOS is associated with a higher BMD and reduced risk of fractures.

Abstract
CONTEXT Osteosarcopenia (loss of skeletal muscle and bone mass and/or function usually associated with aging) shares pathophysiological mechanisms with polycystic ovary syndrome (PCOS). However, the relationship between osteosarcopenia and PCOS remains unclear. OBJECTIVE We evaluated skeletal muscle index% (SMI% = [appendicular muscle mass/weight (kg)] × 100) and bone mineral density (BMD) in PCOS (hyperandrogenism + oligoamenorrhea), and contrasted these musculoskeletal markers against 3 reproductive phenotypes (i): HA (hyperandrogenism + eumenorrhea) (ii); OA (normoandrogenic + oligoamenorrhea) and (iii), controls (normoandrogenic + eumenorrhea). Endocrine predictors of SMI% and BMD were evaluated across the groups. DESIGN, SETTING, AND PARTICIPANTS Multicenter case-control study of 203 women (18-48 years old) in New York State. RESULTS PCOS group exhibited reduced SMI% (mean [95% confidence interval (CI)]; 26.2% [25.1,27.3] vs 28.8% [27.7,29.8]), lower-extremity SMI% (57.6% [56.7,60.0] vs 62.5% [60.3,64.6]), and BMD (1.11 [1.08,1.14] vs 1.17 [1.14,1.20] g/cm2) compared to controls. PCOS group also had decreased upper (0.72 [0.70,0.74] vs 0.77 [0.75,0.79] g/cm2) and lower (1.13 [1.10,1.16] vs 1.19 [1.16,1.22] g/cm2) limb BMD compared to HA. Matsuda index was lower in PCOS vs controls and positively associated with SMI% in all groups (all Ps ≤ 0.05). Only controls showed associations between insulin-like growth factor (IGF) 1 and upper (r = 0.84) and lower (r = 0.72) limb BMD (all Ps < 0.01). Unlike in PCOS, IGF-binding protein 2 was associated with SMI% in controls (r = 0.45) and HA (r = 0.67), and with upper limb BMD (r = 0.98) in HA (all Ps < 0.05). CONCLUSIONS Women with PCOS exhibit early signs of osteosarcopenia when compared to controls likely attributed to disrupted insulin function. Understanding the degree of musculoskeletal deterioration in PCOS is critical for implementing targeted interventions that prevent and delay osteosarcopenia in this clinical population.

Abstract
OBJECTIVE To explore health-related quality of life (HRQoL) among adolescents with polycystic ovary syndrome (PCOS). DESIGN Qualitative study. SETTING Two out-patient gynecology clinics in Yorkshire, England. PARTICIPANTS Fifteen young women diagnosed with PCOS were recruited. METHODS Semistructured interviews were carried out, transcribed verbatim, and subjected to thematic analysis using NVivo software version 2.0. RESULTS A few areas were identified where PCOS had a positive impact upon HRQoL (e.g., improved relationships). However, overall the condition had a negative impact upon HRQoL. Weight problems (in particular the difficulties associated with managing/maintaining weight) and body perceptions appeared to be the most significant contributors to a reduced HRQoL. Menstrual dysfunction, fertility issues, and hirsutism also had adverse affects on emotional well-being, self-perception (including poor body image, self-consciousness, & low self-esteem), social functioning, and sexual behavior. A number of participants described receiving insufficient information from health care professionals (HCPs) and negative experiences in relation to the diagnosis and management of their condition. CONCLUSION Overall, PCOS has a negative impact on the HR QoL of adolescent girls with the condition. Emotional and social functioning appeared to be most affected rather than areas of physical functioning. Future research is needed to identify ways to improve communication between adolescents with PCOS and their HCPs, particularly around the diagnosis and potential for infertility. Finally, HCPs need to be more aware of the emotional impact of PCOS upon adolescents' HRQoL and of the potential for poor sexual health through risk-taking behaviors that may occur due to the potential loss of fertility.

Abstract
BACKGROUND AND AIM Adiponectin is regarded as a possible link between adiposity and insulin resistance. Ghrelin and leptin are considered as signals of energy status. We evaluated the relationships between these peptides, androgens and insulin sensitivity in women affected by polycystic ovary syndrome. METHODS Thirty-six women with PCOS were examined with euglycemic hyperinsulinemic clamp (to determine M/I, index of insulin sensitivity). Leptin, ghrelin, adiponectin, androgens, and SHBG were determined. Statistics was done using correlation analysis and backward stepwise multiple regression. RESULTS The positive correlation of adiponectin with testosterone remains significant even after adjustment for BMI (p = 0.01), M/I (p = 0.009) and for both M/I and BMI (p = 0.02). In multiple regression with testosterone, M/I, leptin and ghrelin as independent variables, the model including testosterone (p = 0.03) and ghrelin (p = 0.002) explained 49% of the variability (p < 0.0012) of adiponectin. CONCLUSIONS Both adiponectin and ghrelin can be involved in the pathophysiology of PCOS but their relation must be delineated further.

Diagnostic and treatment characteristics of polycystic ovary syndrome: descriptive measurements of patient perception and awareness from 657 confidential self-reports. BMC Womens Health 2001; 1:3. [PMID: 11545683 PMCID: PMC55341 DOI: 10.1186/1472-6874-1-3] [Citation(s) in RCA: 57] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2001] [Accepted: 08/22/2001] [Indexed: 01/27/2023] Open
Abstract
BACKGROUND: This investigation was undertaken to describe patient perception and awareness of the polycystic ovary syndrome (PCOS), the most common cause of anovulation/oligoovulation among women of reproductive age. METHODS: Fifteen parameters were evaluated by a computer-based research instrument accessed by a large, unscreened population. Incomplete questionnaires were not entered, and responses were electronically tabulated to block duplicate submissions. RESULTS: From 657 participants, the majority (63%) were between 26-34 years old; mean BMI was 30.4 kg/m2. 343 of 657 had at least one pregnancy and 61% of the study group had taken fertility medicine (any type) at least once. Physicians were the most common provider of PCOS information for all study participants, irrespective of age. Patient emotions associated with the diagnosis of PCOS included "frustration" (67%), "anxiety" (16%), "sadness" (10%), and "indifference" (2%). Self-reported patient aptitude regarding PCOS was scored as high or "very aware" in >60% of women. Respondents were also asked: "If your PCOS could be safely and effectively helped by something else besides fertility drugs or birth control pills, would that interest you?" Interest in alternative PCOS treatments was expressed by 99% of the sample (n = 648). CONCLUSIONS: In our study population, most women associated negative emotions with PCOS although the self-reported knowledge level for the disorder was high. While these women regarded their obstetrician-gynecologist as integral to their PCOS education, traditional PCOS therapies based on oral contraceptives or ovulation induction agents were regarded as unsatisfactory by most women.
