RESUMEN

This analysis of secondary outcome measures of a randomized controlled trial was conducted to study the effect of a one-year three-component (cognitive behavioural therapy, diet, exercise) lifestyle intervention (LSI), with or without additional Short Message Service (SMS) support, on physical activity and aerobic capacity in overweight or obese women with polycystic ovary syndrome (PCOS). Women diagnosed with PCOS and a BMI > 25 kg/m2 were randomly assigned to LSI with SMS support (SMS+, n = 60), LSI without SMS support (SMS-, n = 63) or care as usual (CAU, n = 60) in order to lose weight. Based on results from the International Physical Activity Questionnaire (IPAQ), we found a significant within-group increase after one year for SMS+ in the high physical activity category (+31%, p < 0.01) and sitting behaviour decreased (Δ -871 min/week, p < 0.01). Moreover, the peak cycle ergometer workload increased within SMS+ (Δ +10 watts, p < 0.01). The SMS+ group also demonstrated a significantly different increase in walking metabolic equivalent of task minutes (METmin)/week compared with CAU after one year (Δ 1106 METmin/week, p < 0.05). Apart from this increase in walking activity, no other between-group differences were found in this trial. Overall, based on within-group results, SMS support seemed to help with improving physical activity and aerobic capacity and decreasing sedentary behaviour.

RESUMEN

Women with polycystic ovary syndrome (PCOS) and excess weight often present with reproductive derangements. The first-line treatment for this population is a multi-component lifestyle intervention. This follow-up study of a randomized controlled trial based on data from the Dutch Perinatal registry was conducted to study the effect of a one-year three-component (cognitive behavioral therapy, healthy diet, and exercise) lifestyle intervention on pregnancy outcomes in women with PCOS and overweight or obesity. Women diagnosed with PCOS, a BMI ≥ 25 kg/m², and a wish to conceive were randomized to either three-component lifestyle intervention (LSI, n = 123), and care as usual (CAU, n = 60) where they were encouraged to lose weight autonomously. Conception resulting in live birth was 39.8% (49/123) within LSI and 38.3% (23/60) within CAU (p = 0.845). In total, 58.3% conceived spontaneously. Gestational diabetes (LSI: 8.2% vs. CAU: 21.7%, p = 0.133), hypertensive disorders (LSI: 8.2% vs. CAU 13.0%, p = 0.673), and preterm birth (LSI: 12.2% vs. CAU: 17.4%, p = 0.716) rates were all lower in LSI compared to CAU. This follow-up study showed no significant differences in conception resulting in live birth rates between LSI and CAU. Nonetheless, a large proportion eventually conceived spontaneously. Moreover, after LSI, the number of uneventful pregnancies was lower compared to care as usual.

RESUMEN

INTRODUCTION: Dietary and/or physical activity interventions are often recommended for women with overweight or obesity as the first step prior to fertility treatment. However, randomised controlled trials (RCTs) so far have shown inconsistent results. Therefore, we propose this individual participant data meta-analysis (IPDMA) to evaluate the effectiveness and safety of dietary and/or physical activity interventions in women with infertility and overweight or obesity on reproductive, maternal and perinatal outcomes and to explore if there are subgroup(s) of women who benefit from each specific intervention or their combination (treatment-covariate interactions). METHODS AND ANALYSIS: We will include RCTs with dietary and/or physical activity interventions as core interventions prior to fertility treatment in women with infertility and overweight or obesity. The primary outcome will be live birth. We will search MEDLINE, Embase, Cochrane Central Register of Controlled Trials and trial registries to identify eligible studies. We will approach authors of eligible trials to contribute individual participant data (IPD). We will perform risk of bias assessments according to the Risk of Bias 2 tool and a random-effects IPDMA. We will then explore treatment-covariate interactions for important participant-level characteristics. ETHICS AND DISSEMINATION: Formal ethical approval for the project (Venus-IPD) was exempted by the medical ethics committee of the University Medical Center Groningen (METc code: 2021/563, date: 17 November 2021). Data transfer agreement will be obtained from each participating institute/hospital. Outcomes will be disseminated internationally through the collaborative group, conference presentations and peer-reviewed publication. PROSPERO REGISTRATION NUMBER: CRD42021266201.

RESUMEN

BACKGROUND: Polycystic ovary syndrome (PCOS) affects 5%-10% of women in their reproductive years. Most women with PCOS struggle with obesity during their entire life. Knowing which determinants contribute to a successful lifestyle change is important to optimize treatment options for women with PCOS. OBJECTIVE: This analysis of secondary outcome measures aimed to determine factors of ≥5% weight loss and dropout in all arms of the study and separately in the lifestyle intervention (LI) and control (care as usual [CAU]) groups. STUDY DESIGN: Women diagnosed with PCOS (N = 183) and a Body Mass Index (BMI) above 25 kg/m2 were included. Participants were assigned to (1) 20 lifestyle sessions involving cognitive behavioral therapy (CBT), (2) 20 lifestyle sessions involving CBT with additional short message service (SMS), or (3) to control (CAU). A generalized linear regression was performed to identify determinants of ≥5% weight loss. Logistic regression was performed to identify determinants of dropout. All models were corrected by including baseline weight as a covariate. RESULTS: LI (OR 4.906, p = .001) was associated with ≥5% weight loss, while higher depression scores (OR 0.549, p = .013) had a negative association. Restraint eating was a positive factor for ≥5% weight loss in LI but a negative in CAU. Higher baseline weight (OR 1.033, p = .006), LI with SMS (OR 4.424, p = .002), and higher levels of androstenedione (OR 1.167, p = .026) were associated with dropout. CONCLUSIONS: Depression and eating behavior were associated with ≥5% weight loss. Women with PCOS should be screened for depression and eating behavior before a LI.

RESUMEN

OBJECTIVE: To assess the effects of aging on the features of polycystic ovary syndrome (PCOS). DESIGN: Cohort study. SETTING: Tertiary care center. PATIENT(S): Women with PCOS, diagnosed according to the 2003 Rotterdam criteria, who visited our outpatient clinic repeatedly. INTERVENTION(S): Comparisons were made between the first visit and consecutive visits. MAIN OUTCOME MEASURE(S): Change in PCOS phenotype groups in terms of clinical and endocrine characteristics. RESULT(S): A total of 596 women visited the outpatient clinic repeatedly. An estimated change per 5-year age showed a decrease in the prevalence of phenotype A and an increase in the prevalence of not having PCOS. The serum levels of testosterone, androstenedione, and dehydroepiandrosterone sulfate as well as the free androgen index decreased significantly. Clinical characteristics showed an increase in terms of body mass index and waist circumference, whereas plasma glucose levels, insulin levels, and insulin resistance did not change significantly. CONCLUSION(S): The prevalence of PCOS phenotype groups changes over time. There is an important age effect that indicates a more regular menstrual cycle, decrease in the serum androgen levels, and improvement in polycystic ovarian morphology when aging occurs in women with PCOS.

RESUMEN

CONTEXT: Women with polycystic ovary syndrome (PCOS) have an increased risk of metabolic syndrome (MetS). Both PCOS and MetS are associated with excess weight. OBJECTIVE: To examine the effect of a three-component lifestyle intervention (LSI) with or without short message service (SMS+ or SMS-, respectively) on the prevalence and severity of MetS and metabolic parameters, compared to care as usual (CAU). DESIGN: Randomized controlled trial. METHODS: Women diagnosed with PCOS and a BMI >25 kg/m2 (n = 183) were either assigned to a 1-year three-component (cognitive behavioural therapy, diet, and exercise) LSI, with or without SMS support, or to CAU which provided weight-loss advice only. Main outcome measures included changes in the prevalence of MetS, the continuous MetS severity z-score (cMetS z-score), metabolic parameters, and the impact of weight loss. RESULTS: After 1 year, the decrease in the cMetS z-score was greater in the SMS+ group than the CAU group (-0.39, P = 0.015). The prevalence of MetS changed with -21.6% (P = 0.037), -16.5% (P = 0.190), and +7.0% (P = 0.509) in both LSI groups and CAU group, respectively. A post hoc analysis for both LSI groups combined vs CAU resulted in a MetS difference of -25.9% (P = 0.046). Moreover, weight loss per se resulted in significantly favourable effects on all metabolic parameters. CONCLUSIONS: This three-component LSI was more successful in improving metabolic health compared to CAU. Therefore, we recommend this intervention to women with PCOS and excess weight, provided that a clinically relevant weight loss is being pursued.

RESUMEN

OBJECTIVE: To determine a cutoff for the Elecsys AMH Plus immunoassay (Roche Diagnostics International Ltd, Rotkreuz, Switzerland) to identify polycystic ovarian morphology (PCOM), a polycystic ovary syndrome (PCOS) criterion. DESIGN: The AMH Protein in Humans for polycystic ovaRian mOrphology DIagnostic TEsting (APHRODITE) study was a retrospective, multicenter, case-control study. The serum antimüllerian hormone (AMH) level was measured using the Elecsys AMH Plus immunoassay. The antral follicle count was determined using transvaginal ultrasound. An AMH cutoff was derived and validated in separate cohorts with cases of PCOS with full phenotype A (oligo/anovulation, hyperandrogenism, and PCOM) versus that with controls. Exploratory analyses of age and PCOS phenotype were performed. SETTING: Not applicable. PATIENT(S): Polycystic ovary syndrome-positive (PCOS A-D per the Rotterdam criteria) and PCOS-negative women aged 25-45 years. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): A validated cutoff for AMH using the Elecsys AMH Plus assay for PCOM. RESULT(S): In the validation cohort (455 cases and 500 controls), an AMH cutoff of 3.2 ng/mL (23 pmol/L) resulted in a sensitivity of 88.6% (95% confidence interval [CI] 85.3-91.3) and specificity of 84.6% (95% CI 81.1-87.7) for PCOM diagnosis as well as an area under the receiver-operator characteristic curve of 93.6% (95% CI 92.2-95.1). In women aged 25-35 years, the sensitivity and specificity for the cutoff were 88.5% and 80.3%, respectively, versus 77.8% and 90.1%, respectively, in women aged 36-45 years. The results were consistent across PCOS phenotypes A-D. CONCLUSION(S): The Elecsys AMH Plus immunoassay, with a cutoff of 3.2 ng/mL (23 pmol/L), is a robust method for identifying PCOM to aid in PCOS diagnosis.

RESUMEN

RESEARCH QUESTION: What is the effect of weight loss through different interventions (three-component lifestyle intervention with short message service [SMS+] versus three-component lifestyle intervention without SMS [SMS-] versus care as usual [CAU]) on polycystic ovary syndrome (PCOS) characteristics (ovulatory dysfunction, hyperandrogenism, polycystic ovarian morphology [PCOM]) and phenotype distribution? DESIGN: Analysis of secondary outcome measures of a randomized controlled trial. Women diagnosed with PCOS (n = 183), who wished to become pregnant, with a body mass index above 25 kg/m², were assigned to a 1-year three-component (cognitive behavioural therapy, diet, exercise) lifestyle intervention group, with or without SMS, or to CAU (advice to lose weight). RESULTS: The prevalence of biochemical hyperandrogenism was 30.9% less in the SMS- group compared with CAU after 1 year (P = 0.027). Within-group analyses revealed significant improvements in ovulatory dysfunction (SMS+: -39.8%, P = 0.001; SMS-: -30.5%, P = 0.001; CAU: -32.1%, P < 0.001), biochemical hyperandrogenism (SMS-: -27.8%, P = 0.007) and PCOM (SMS-: -14.0%, P = 0.034). Weight loss had a significantly favourable effect on the chance of having ovulatory dysfunction (estimate 0.157 SE 0.030, P < 0.001) and hyperandrogenism (estimate 0.097 SE 0.027, P < 0.001). CONCLUSIONS: All groups demonstrated improvements in PCOS characteristics, although these were more profound within the lifestyle intervention groups. Weight loss per se led to an amelioration of diagnostic characteristics and in the phenotype of PCOS. A three-component lifestyle intervention aimed at a 5-10% weight loss should be recommended for all women with PCOS before they become pregnant.

RESUMEN

OBJECTIVE: Long-term weight loss is important and difficult to achieve for many women with polycystic ovary syndrome (PCOS). Lifestyle interventions (LS) in PCOS have shown moderate short-term effects. Three-component LS that combine nutrition advice, exercise, and cognitive behavioral therapy have not been tested in long-term interventions. METHODS: Women (N = 183) with PCOS who were trying to conceive and had BMI > 25 kg/m2 were assigned to 20 group sessions of cognitive behavioral therapy combined with nutrition advice and exercise (LS with or without Short Message Service [SMS] via mobile phone) or care as usual (CAU). RESULTS: More weight loss was observed in LS than in CAU (P < 0.001). Adding SMS was even more effective (P = 0.017). In CAU, 13 of 60 (21.8%) succeeded in achieving a 5% weight loss, as did 32 of 60 (52.8%) in LS without SMS and 54 of 63 (85.7%) in LS with SMS. The odds of achieving a 5% weight loss were 7.0 (P < 0.001) in LS compared with CAU. More than 18 of 60 (29.0%) of the women in CAU gained weight versus 5 of 60 (8.5%) and 2 of 63 (3.1%) in LS without or with SMS, respectively. The overall dropout rate was 116 of 183 (63.4%). CONCLUSIONS: A three-component LS program resulted in reasonable weight loss in women with PCOS. Adding SMS resulted in more weight loss.

RESUMEN

Many women with Polycystic Ovary Syndrome (PCOS) report high depression rates. The relationship between PCOS and these high depression rates is unclear. Two-component lifestyle interventions have revealed short-term effects on depression scores in this group of women. In general, 3-component interventions including diet, exercise, and cognitive behavioral therapy (CBT) are more effective in the long-term to improve emotional well-being. This has not yet been studied in women with PCOS. This study examined the effect of 20 CBT lifestyle (LS) sessions combined with a healthy diet and physical therapy with or without 9 months additional feedback through Short Message Service (SMS) via mobile phone, compared to care as usual (CAU, involving advice to lose weight). In this secondary analysis, 155 women with PCOS and a BMI above 25 kg/m2 were eligible. Depression scores decreased significantly in the LS programme compared to CAU (P = 0.045). In both the LS programme without SMS (P = 0.036) and the LS programme with SMS (P = 0.011) depression scores decreased while no change was observed in CAU (P = 0.875). Self-esteem scores improved significantly in the LS programme compared to CAU (P = 0.027). No differences in body image scores were observed in LS participants compared to CAU (P = 0.087), although body image improved significantly in both the LS without SMS (P = 0.001) and with SMS (P = 0.008) study arms. We found no significant mediating role by androgens in the relationship between LS participants and emotional well-being. Only weight-loss mediated the relationship between LS and self-esteem. To conclude, a three-component lifestyle intervention programme with or without additional SMS resulted in significant improvements in depression and self-esteem compared to CAU, in women with PCOS, obesity, and a wish to achieve a pregnancy. Testosterone, androstenedione, DHEA, insulin, HOMA-IR, and cortisol did not mediate this effect. Weight loss mediated the effects on self-esteem but not on depression and body-image. This suggests that lifestyle treatment independent of weight loss can reduce depression and body-image, but both lifestyle treatment and weight loss can improve self-esteem. Thus, a three-component lifestyle intervention based on CBT could prove successful in improving mood in women with PCOS who are overweight or obese and attempting to become pregnant.
