Lifestyle management improves quality of life and depression in overweight and obese women with polycystic ovary syndrome

Dietary intake, eating behaviors, and quality of life in women with polycystic ovary syndrome who are trying to conceive

The Healthy Eating for Reproductive Health study was conducted among 18 (45% non-white) mostly obese (BMI 39.9 ± 6.1) women with polycystic ovary syndrome (PCOS) who were experiencing infertility and interested in losing weight. A variety of markers were measured at baseline: body mass index (BMI), diet, physical activity, eating behaviors (using an Eating Behavior Inventory, a questionnaire which assesses both positive and negative eating behaviors associated with weight status, with a higher score indicating adoption of eating behaviors which have been shown in prior weight-loss research to promote a healthy weight (EBI) and the Three-Factor Eating Questionnaire, which assesses cognitive and behavioral components of eating among overweight adults), and a quality of life (PCOS Health-Related Quality of Life (PCOSQ)) index, which assesses satisfaction around five 'domains': emotional health, presence of body hair, infertility, weight, and menstrual problems). A comparison group of overweight women without PCOS (n = 28) was used to examine differences in measured outcomes between women with and without PCOS. Participants' habitual diets were high in fat and saturated fat and low in fiber, folate, and iron and contained significantly lower amounts of carbohydrate, iron, and whole grains compared with women without PCOS who had enrolled in a behavioral weight loss programme. Participants had a low EBI (indicating that most were not adopting eating behaviors associated with achieving a healthy weight), disinhibition (indicating participants had a tendency to overeat in the presence of highly palatable foods or were susceptible to emotional cues for eating, such as stress), and hunger scores (indicating participants did not report being susceptible to hunger, prompting overeating) and moderate dietary restraint (indicating they were not consistently attempting to restrict food intake consciously). PCOSQ scores were lowest for infertility and weight domains (indicating low satisfaction with current infertility and weight status); however all domains received low scores (emotional health, body hair, and menstrual problems). Higher energy intakes (kcal/day) were associated with a lower EBI score (r = - 0.60, P = 0.02), lower dietary restraint (r =- 0.50, P = 0.04), and higher disinhibition (r = 0.63, P = 0.01). Greater energy expenditure (kcal/day) was associated with lower PCOSQ scores for body weight (r =-0.54, P = 002) and infertility (r =- 0.51, P = 0.003) domains. Results suggest that overweight women with PCOS-related infertility have poor dietary intake, particularly in terms of whole grains, fiber, and iron, and eating behaviors inconsistent with achieving a healthy body weight, as well as low scores for PCOS-related quality of life.

Physical activity and mental health in women with polycystic ovary syndrome

Background

Physical activity is prescribed as a component of primary management for Polycystic Ovary Syndrome (PCOS). This study investigates the association between physical activity and mental health as well as the exercise barriers, motivators and support providers for younger women with and without PCOS to assist in physical activity uptake and prescription for these women.

Methods

Women aged 18-50 years with (n = 153) and without PCOS (n = 64) completed a questionnaire at one time point. The questionnaire included the Hospital Anxiety and Depression Scale and a survey regarding levels of physical activity, physical activity barriers, motivators and supports. A MANCOVA assessed associations between physical activity, PCOS and mental health (specifically depression and anxiety). Descriptive and Chi square goodness of fit statistics assessed the differences in perceived barriers, motivators and support providers amongst women with and without PCOS.

Results

Women with PCOS displayed higher severity of depression (F(1,210) = 8.32, p = 0.004) and anxiety (F(1,210) = 17.37, p < 0.001) symptoms compared to controls. Overall, for physically active women, depression was significantly less severe than in their inactive counterparts (F(2,210) = 13.62, p < 0.001). There were no differences in anxiety by physical activity status and no interaction effects between PCOS and activity status for depression or anxiety. Women with PCOS were more likely to report a lack of confidence about maintaining physical activity (Χ² = 3.65; p = 0.046), fear of injury (Χ² = 4.08; p = 0.043) and physical limitations (Χ² = 11.92; p = 0.001) as barriers to physical activity and were more likely to be motivated to be active to control a medical condition (Χ² = 7.48; p = 0.006). Women with PCOS identified more sources of support compared to women without PCOS.

Conclusions

Physical activity is associated with lower depression in women with PCOS and differences exist in the self-reported physical activity barriers, motivators and support providers, compared to controls. Being more active may offer mental health benefits in managing PCOS. Prescribing physical activity to women with PCOS should be individualized and consider both common and PCOS-specific barriers and motivators for successful engagement.

Supportive relationships--psychological effects of group counselling in women with polycystic ovary syndrome (PCOS)

The objective of the present study was to examine the psychological impact of a group-oriented approach to disease management and health behaviour in women with polycystic ovary syndrome (PCOS). Seventeen overweight PCOS women were randomised in a crossover design of eight weeks high-intensity aerobic exercise followed by eight weeks of group counselling (n=8) or vice versa (n=9). Interpersonal communication, emotional and relational aspects were observed and analysed throughout the period focusing on changes in health behaviour. The most salient findings showed supportive relationships expressed as group cohesion, exchange of narratives of illness and of disorder-specific aspects. Individual relationships between the participants were important for changes in behaviour, especially those generating feedback from the other participants and reducing social isolation. The results were most encouraging in the group that had initial counselling sessions before the physical intervention. It can be concluded that group counselling sessions focusing on supportive relationships followed by high-intensity aerobic training have beneficial effects on wellbeing, health and exercise behaviour.

Weight loss on a structured hypocaloric diet with or without exercise improves emotional distress and quality of life in overweight and obese patients with type 2 diabetes

AIMS/INTRODUCTION

To evaluate the effects of a caloric restricted weight loss program with or without supervised resistance exercise training (EX) on diabetes-related emotional distress and quality of life (QOL) in overweight and obese patients with type 2 diabetes.

MATERIALS AND METHODS

In a parallel design, 106 men and women with type 2 diabetes were randomized to a prescriptive 16-week caloric restricted diet (D; 6,000-7,000 kJ/day), with (n = 65) or without (n = 41) EX (three times per week). Bodyweight, glycated hemoglobin, diabetes-specific emotional distress (Problem Areas in Diabetes [PAID] questionnaire) and QOL (Diabetes-39 [D-39] questionnaire) was assessed pre- and post-intervention.

RESULTS

A total of 84 participants completed the study (D n = 33, D + EX n = 51). Weight loss was significantly greater in D + EX compared with D (-11.4 ± 5.8 vs -8.8 ± 5.8 kg, P = 0.04 time × diet). Overall, there were significant improvements in glycated hemoglobin, PAID total score and the D-39 dimensions of 'diabetes control', 'anxiety and worry', 'sexual functioning', 'energy and mobility', 'overall rating of QOL' and 'severity of diabetes' (P ≤ 0.01 for time). The D-39 dimension, 'social burden', did not change (P = 0.07 for time). There was no difference between groups in the response for any of these variables (P ≥ 0.10).

CONCLUSION

A structured caloric restricted diet with or without EX improves emotional distress and QOL in overweight and obese patients with type 2 diabetes. This trial was registered with Australian New Zealand Clinical Trials Registry (http://www.anzctr.org.au; ACTR No: ACTRN12608000206325).

A life course perspective on polycystic ovary syndrome

Polycystic ovary syndrome (PCOS) is a major public health problem in the US. Worldwide, the public is largely unaware of the condition and health care providers do not seem to fully understand it. Research on PCOS has primarily focused on its etiology and clinical characteristics and less on the psychosocial aspects of human development associated with PCOS. This paper posits that a life course perspective provides a framework for further understanding the psychosocial experiences of women with PCOS and the contexts in which they live. The paper discusses how life course principles of human development, constraints on agency, interdependence of lives, time and place, and timing of events and experiences are relevant to the management of PCOS and prevention of its complications.

Effect of lifestyle intervention on the reproductive endocrine profile in women with polycystic ovarian syndrome: a systematic review and meta-analysis

Polycystic ovarian syndrome (PCOS) affects 18-22% of women at reproductive age. We conducted a systematic review and meta-analysis evaluating the expected benefits of lifestyle (exercise plus diet) interventions on the reproductive endocrine profile in women with PCOS. Potential studies were identified by systematically searching PubMed, CINAHL and the Cochrane Controlled Trials Registry (1966-April 30, 2013) systematically using key concepts of PCOS. Significant improvements were seen in women receiving lifestyle intervention vs usual care in follicle-stimulating hormone (FSH) levels, mean difference (MD) 0.39 IU/l (95% CI 0.09 to 0.70, P=0.01), sex hormone-binding globulin (SHBG) levels, MD 2.37 nmol/l (95% CI 1.27 to 3.47, P<0.0001), total testosterone levels, MD -0.13 nmol/l (95% CI -0.22 to -0.03, P=0.008), androstenedione levels, MD -0.09 ng/dl (95% CI -0.15 to -0.03, P=0.005), free androgen index (FAI) levels, MD -1.64 (95% CI -2.94 to -0.35, P=0.01) and Ferriman-Gallwey (FG) score, MD -1.01 (95% CI -1.54 to -0.48, P=0.0002). Significant improvements were also observed in women who received exercise-alone intervention vs usual care in FSH levels, MD 0.42 IU/l (95% CI 0.11 to 0.73, P=0.009), SHBG levels, MD 3.42 nmol/l (95% CI 0.11 to 6.73, P=0.04), total testosterone levels, MD -0.16 nmol/l (95% CI -0.29 to -0.04, P=0.01), androstenedione levels, MD -0.09 ng/dl (95% CI -0.16 to -0.03, P=0.004) and FG score, MD -1.13 (95% CI -1.88 to -0.38, P=0.003). Our analyses suggest that lifestyle (diet and exercise) intervention improves levels of FSH, SHBG, total testosterone, androstenedione and FAI, and FG score in women with PCOS.

Lifestyle intervention and anti-obesity therapies in the polycystic ovary syndrome: impact on metabolism and fertility

Obesity is frequently present in patients with polycystic ovary syndrome (PCOS) and plays an important role in the pathogenesis of the metabolic, endocrine, and reproductive abnormalities associated with this syndrome. We aimed to summarize the effects of lifestyle changes and anti-obesity pharmacotherapy in patients with PCOS. We reviewed the literature regarding the effects of lifestyle changes and anti-obesity agents on the metabolic and endocrine abnormalities of PCOS. Lifestyle changes, including diet, exercise, and behavioral modification, appear to improve the metabolic and reproductive abnormalities of overweight and obese patients with PCOS. Therefore, lifestyle changes appear to represent the first-line management for all overweight and obese patients with PCOS. However, the optimal composition of diet and the optimal type of exercise in these patients are unknown. Anti-obesity agents that have been studied in PCOS include orlistat, sibutramine, and rimonabant. However, the latter two agents have been withdrawn from the market because of side effects. Long-term studies with orlistat in overweight and obese diabetic patients showed greater weight loss and metabolic and cardiovascular benefits than those achieved with lifestyle changes alone. However, there are limited data on the efficacy of orlistat in women with PCOS. In conclusion, lifestyle changes (diet, exercise and behavioral modification), particularly when combined with anti-obesity agents, exert beneficial effects on the endocrine abnormalities of obese patients with PCOS and improve metabolic parameters.

Anxiety, cognitive, and depressive assessment in adolescents with polycystic ovarian syndrome: a pilot study

STUDY OBJECTIVE

Polycystic ovarian syndrome (PCOS) is a major endocrine disorder afflicting women of reproductive age group. Women with PCOS suffer from depressive and anxiety disorders and they are more likely to be depressed compared to healthy women. However, no studies have assayed the perception of the clinical manifestations of PCOS in the adolescent group. In this study, we aimed at analyzing the anxiety, cognitive, and depressive states of adolescent girls with PCOS.

DESIGN

A total of 37 adolescents presenting to a tertiary care center in Lebanon and aged 14-18 years participated in the current study. Socio-economic and demographic data were collected and self-reported questionnaires (FSIQ, SDQ, SCARED, and BDI) were presented to the study group and analyzed.

RESULTS

The FSIQ levels among adolescents with PCOS were significantly lower compared to healthy controls. Surprisingly, there were no differences between the adolescent girls with PCOS and the healthy age-matched girls in the anxiety and depressive states and in psychiatric symptoms.

CONCLUSIONS

This is the first study to assay for cognitive, anxiety, and depressive states in adolescent girls. No major differences were found among both groups except in cognitive levels. However, long-term follow-up for proper management of psychiatric disorders is warranted. Moreover, the latency of androgens and its contribution to psychiatric illnesses in women with PCOS could be a major factor for development of psychiatric symptoms, rather than the hyperandrogenic levels per se.

Exercise for depression

BACKGROUND

Depression is a common and important cause of morbidity and mortality worldwide. Depression is commonly treated with antidepressants and/or psychological therapy, but some people may prefer alternative approaches such as exercise. There are a number of theoretical reasons why exercise may improve depression. This is an update of an earlier review first published in 2009.

OBJECTIVES

To determine the effectiveness of exercise in the treatment of depression in adults compared with no treatment or a comparator intervention.

SEARCH METHODS

We searched the Cochrane Depression, Anxiety and Neurosis Review Group's Controlled Trials Register (CCDANCTR) to 13 July 2012. This register includes relevant randomised controlled trials from the following bibliographic databases: The Cochrane Library (all years); MEDLINE (1950 to date); EMBASE (1974 to date) and PsycINFO (1967 to date). We also searched www.controlled-trials.com, ClinicalTrials.gov and the WHO International Clinical Trials Registry Platform. No date or language restrictions were applied to the search.We conducted an additional search of the CCDANCTR up to 1st March 2013 and any potentially eligible trials not already included are listed as 'awaiting classification.'

SELECTION CRITERIA

Randomised controlled trials in which exercise (defined according to American College of Sports Medicine criteria) was compared to standard treatment, no treatment or a placebo treatment, pharmacological treatment, psychological treatment or other active treatment in adults (aged 18 and over) with depression, as defined by trial authors. We included cluster trials and those that randomised individuals. We excluded trials of postnatal depression.

DATA COLLECTION AND ANALYSIS

Two review authors extracted data on primary and secondary outcomes at the end of the trial and end of follow-up (if available). We calculated effect sizes for each trial using Hedges' g method and a standardised mean difference (SMD) for the overall pooled effect, using a random-effects model risk ratio for dichotomous data. Where trials used a number of different tools to assess depression, we included the main outcome measure only in the meta-analysis. Where trials provided several 'doses' of exercise, we used data from the biggest 'dose' of exercise, and performed sensitivity analyses using the lower 'dose'. We performed subgroup analyses to explore the influence of method of diagnosis of depression (diagnostic interview or cut-off point on scale), intensity of exercise and the number of sessions of exercise on effect sizes. Two authors performed the 'Risk of bias' assessments. Our sensitivity analyses explored the influence of study quality on outcome.

MAIN RESULTS

Thirty-nine trials (2326 participants) fulfilled our inclusion criteria, of which 37 provided data for meta-analyses. There were multiple sources of bias in many of the trials; randomisation was adequately concealed in 14 studies, 15 used intention-to-treat analyses and 12 used blinded outcome assessors.For the 35 trials (1356 participants) comparing exercise with no treatment or a control intervention, the pooled SMD for the primary outcome of depression at the end of treatment was -0.62 (95% confidence interval (CI) -0.81 to -0.42), indicating a moderate clinical effect. There was moderate heterogeneity (I² = 63%).When we included only the six trials (464 participants) with adequate allocation concealment, intention-to-treat analysis and blinded outcome assessment, the pooled SMD for this outcome was not statistically significant (-0.18, 95% CI -0.47 to 0.11). Pooled data from the eight trials (377 participants) providing long-term follow-up data on mood found a small effect in favour of exercise (SMD -0.33, 95% CI -0.63 to -0.03).Twenty-nine trials reported acceptability of treatment, three trials reported quality of life, none reported cost, and six reported adverse events.For acceptability of treatment (assessed by number of drop-outs during the intervention), the risk ratio was 1.00 (95% CI 0.97 to 1.04).Seven trials compared exercise with psychological therapy (189 participants), and found no significant difference (SMD -0.03, 95% CI -0.32 to 0.26). Four trials (n = 300) compared exercise with pharmacological treatment and found no significant difference (SMD -0.11, -0.34, 0.12). One trial (n = 18) reported that exercise was more effective than bright light therapy (MD -6.40, 95% CI -10.20 to -2.60).For each trial that was included, two authors independently assessed for sources of bias in accordance with the Cochrane Collaboration 'Risk of bias' tool. In exercise trials, there are inherent difficulties in blinding both those receiving the intervention and those delivering the intervention. Many trials used participant self-report rating scales as a method for post-intervention analysis, which also has the potential to bias findings.

AUTHORS' CONCLUSIONS

Exercise is moderately more effective than a control intervention for reducing symptoms of depression, but analysis of methodologically robust trials only shows a smaller effect in favour of exercise. When compared to psychological or pharmacological therapies, exercise appears to be no more effective, though this conclusion is based on a few small trials.

Acupuncture and physical exercise for affective symptoms and health-related quality of life in polycystic ovary syndrome: secondary analysis from a randomized controlled trial

Background

Women with polycystic ovary syndrome (PCOS) have symptoms of depression and anxiety and impaired health related quality of life (HRQoL). Here we test the post-hoc hypothesis that acupuncture and exercise improve depression and anxiety symptoms and HRQoL in PCOS women.

Methods

Seventy-two PCOS women were randomly assigned to 16 weeks of 1) acupuncture (n = 28); 2) exercise (n = 29); or 3) no intervention (control) (n = 15). Outcome measures included: change in Montgomery Åsberg Depression Rating Scale (MADRS-S), Brief Scale for Anxiety (BSA-S), Swedish Short-Form 36 (SF-36), and PCOS Questionnaire (PCOSQ) scores from baseline to after 16-week intervention, and to 16-week post-intervention follow-up.

Results

A reduction in MADRS-S and BSA-S from baseline to 16-weeks post-intervention follow-up was observed for the acupuncture group. The SF-36 domains role physical, energy/vitality, general health perception and the mental component of summary scores improved in the acupuncture group after intervention and at follow-up. Within the exercise group the role physical decreased after treatment, while physical functioning and general health perception scores increased at follow-up. The emotion domain in the PCOSQ improved after 16-weeks of intervention within all three groups, and at follow-up in acupuncture and exercise groups. At follow-up, improvement in the infertility domain was observed within the exercise group.

Conclusion

There was a modest improvement in depression and anxiety scores in women treated with acupuncture, and improved HRQoL scores were noted in both intervention groups. While not a primary focus of the trial, these data suggest continued investigation of mental health outcomes in women treated for PCOS.

The psychological wellbeing of patients following excision of a pilonidal sinus

OBJECTIVE

To explore the effects of a pilonidal sinus wound on patients' psychological wellbeing.

METHOD

An interpretive descriptive approach, using the Model of Living conceptual framework, guided data collection and analysis. The Model of Living was chosen to elicit information on how a pilonidal sinus wound affected activities of living. Participants were recruited from a database of a community nursing service, using purposive sampling, until data saturation was evident. Semi-structured interviews were used to collect the data. Data were examined for frequent patterns, which were organised into themes.

RESULTS

Seven males and four females with ages ranging 17-39 years were selected through purposive sampling. Five participants reported that their wound affected their psychological wellbeing. Three themes and eight sub themes were identified from the data: adaption, perception and control. Depression and stress were associated with pain, physical inactivity, body weight changes and delayed wound healing.

CONCLUSION

A pilonidal sinus wound can affect the psychological wellbeing of patients through pain,physical inactivity, changed body weight and delayed wound healing. Pre-existing conditions could also be exacerbated by the wound.

The effect of obesity on polycystic ovary syndrome: a systematic review and meta-analysis

While many women with polycystic ovary syndrome (PCOS) are overweight, obese or centrally obese, the effect of excess weight on the outcomes of PCOS is inconsistent. The review aimed to assess the effects of overweight, obesity and central obesity on the reproductive, metabolic and psychological features of PCOS. MEDLINE, EMBASE, CINAHL, Cochrane Central Register of Controlled Trials (CENTRAL) and PSYCINFO were searched for studies reporting outcomes according to body mass index categories or body fat distribution. Data were presented as mean difference or risk ratio (95% confidence interval). This review included 30 eligible studies. Overweight or obese women with PCOS had decreased sex hormone-binding globulin (SHBG), increased total testosterone, free androgen index, hirsutism, fasting glucose, fasting insulin, homeostatic model assessment-insulin resistance index and worsened lipid profile. Obesity significantly worsened all metabolic and reproductive outcomes measured except for hirsutism when compared to normal weight women with PCOS. Overweight women had no differences in total testosterone, hirsutism, total-cholesterol and low-density lipoprotein-cholesterol compared to normal weight women and no differences in SHBG and total testosterone compared to obese women. Central obesity was associated with higher fasting insulin levels. These results suggest that prevention and treatment of obesity is important for the management of PCOS.

Effect of holistic yoga program on anxiety symptoms in adolescent girls with polycystic ovarian syndrome: A randomized control trial

Context:

Yoga techniques practiced for varying durations have been shown to reduce state anxiety. This was never assessed in adolescents with polycystic ovarian syndrome (PCOS).

Aims:

To compare the effect of a holistic yoga program with the conventional exercise program on anxiety level in adolescents with PCOS.

Settings and Design:

Ninety adolescent (15-18 years) girls from a residential college in Andhra Pradesh, who satisfied the Rotterdam criteria, were randomized into two groups.

Materials and Methods:

Anxiety levels were assessed at inclusion and after 12 weeks of intervention wherein yoga group practiced a holistic yoga module while the control group practiced a matching set of physical exercises (1 h/day, for 12 weeks).

Statistical Analysis Used:

Mann-Whitney U test was used to compare difference scores (delta change) between the two groups

Results:

Changes in state anxiety after the intervention were nonsignificantly different between the two groups (P=0.243), while changes after the intervention were significantly different between the two groups (P=0.002) for trait anxiety.

Conclusions:

Twelve weeks of a holistic yoga program in adolescents with PCOS is significantly better than physical exercise program in reducing anxiety symptoms.

Effectiveness of diet versus exercise intervention on weight reduction in local Japanese residents

OBJECTIVE

To evaluate the effect of diet versus exercise intervention on weight reduction.

METHODS

Participants were randomly divided by gender, age, and living area into four groups: group DE (diet and exercise, n = 16), group D (diet only, n = 15), group E (exercise only, n = 15), and group C (control, n = 16). This study ultimately aimed to help participants reduce their body mass index (BMI) by 7% of baseline value. Subjects were 62 residents (men and women ranging in age from 40 to 69 years) of two residential areas in Nara Prefecture, Japan, who participated in annual health checkups in 2006. BMI of the participants was ≥24 and <28 kg/m² at baseline examination. All participants agreed to undergo a 6-month intervention between January 2007 and September 2007.

RESULTS

In our intention-to-treat analysis, mean change in BMI from baseline to final examination was as follows: group DE mean BMI decreased 6.6%, group D mean BMI decreased 5.3%, group E mean BMI decreased 2.3%, and group C mean BMI decreased 2.2%. The reduction in BMI from baseline to final examination was significant in all groups (DE, p < 0.001; D, p < 0.001; E, p = 0.009; C, p = 0.019). Further, mean abdominal circumference was significantly reduced in all groups. Blood glucose levels were significantly reduced only in group DE (p = 0.047).

CONCLUSION

Combined intervention with diet and exercise proved to be effective in weight reduction, whereas exercise intervention alone was not found to be effective.

How does lifestyle intervention affect depressive symptoms? Results from the Finnish Diabetes Prevention Study

AIMS

To assess the effect of lifestyle intervention on depressive symptoms during a 36-month randomized clinical trial designed to prevent Type 2 diabetes.

METHODS

A total of 522 middle-aged participants, who were overweight or obese and had impaired glucose tolerance, were randomized to the lifestyle intervention or control group in the Finnish Diabetes Prevention Study. The intervention group received individualized counselling aimed at reducing weight and increasing physical activity. Depressive symptoms were measured using the Beck Depression Inventory among a subgroup of 140 participants.

RESULTS

On study entry, the mean Beck Depression Inventory scores ± sd were 6.8 ± 5.6 in the intervention group and 6.7 ± 5.5 in the control group. Beck Depression Inventory scores reduced during the intervention study: the mean ± sd (95% CI) reduction was 0.90 ± 4.54 (-1.99 to -0.19) scores in the intervention group and 0.75 ± 4.47 (-1.80 to 0.31) in the control group, with no difference between the groups. In a stepwise linear multivariate regression analysis, the variables with the strongest associations with the change in Beck Depression Inventory scores were baseline Beck Depression Inventory scores, marital status, weight change and change of total energy intake (R(2) = 0.209, P < 0.001).

CONCLUSIONS

Participation in the study lowered depression scores, with no specific group effect. Among the lifestyle changes, particularly successful reduction of body weight was associated with the greater reduction of depressive symptoms. Thus, regardless of the intensity of the treatment, the success in executing alterations in one's lifestyle and behaviour is associated with beneficial changes in mood.

Effect of a yoga program on glucose metabolism and blood lipid levels in adolescent girls with polycystic ovary syndrome

OBJECTIVE

To assess the efficacy of yoga therapy on glucose metabolism and blood lipid values in adolescent girls with polycystic ovary syndrome (PCOS).

METHODS

A prospective, randomized, interventional controlled trial recruited 90 adolescents aged between 15 and 18 years who met the Rotterdam criteria for PCOS. A yoga group practiced suryanamaskara, asanas, pranayama, and meditation 1 hour per day each day for 12 weeks while another group practiced conventional physical exercises. The Mann-Whitney U test was used to compare score changes between the 2 groups.

RESULTS

The changes in fasting insulin, fasting blood glucose, and homeostasis model assessment of insulin resistance were significantly different in the 2 groups (P<0.05). Except for high-density lipoprotein cholesterol, the changes in blood lipid values were also significantly different (P<0.05). The changes in body mass index, waist circumference, hip circumference, and waist-to-hip ratio, however, were not significantly different (P>0.05).

CONCLUSION

Yoga was found to be more effective than conventional physical exercises in improving glucose, lipid, and insulin values, including insulin resistance values, in adolescent girls with PCOS independent of anthropometric changes. Central Trial Registry of India No.: REFCTRI-2008 000291.

Consensus on women's health aspects of polycystic ovary syndrome (PCOS): the Amsterdam ESHRE/ASRM-Sponsored 3rd PCOS Consensus Workshop Group

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in females, with a high prevalence. The etiology of this heterogeneous condition remains obscure, and its phenotype expression varies. Two widely cited previous ESHRE/ASRM sponsored PCOS consensus workshops focused on diagnosis (published in 2004) and infertility management (published in 2008), respectively. The present third PCOS consensus report summarizes current knowledge and identifies knowledge gaps regarding various women's health aspects of PCOS. Relevant topics addressed-all dealt with in a systematic fashion-include adolescence, hirsutism and acne, contraception, menstrual cycle abnormalities, quality of life, ethnicity, pregnancy complications, long-term metabolic and cardiovascular health, and finally cancer risk. Additional, comprehensive background information is provided separately in an extended online publication.

Sex steroids, insulin sensitivity and sympathetic nerve activity in relation to affective symptoms in women with polycystic ovary syndrome

CONTEXT

Affective symptoms are poorly understood in polycystic ovary syndrome (PCOS). Clinical signs of hyperandrogenism and high serum androgens are key features in PCOS, and women with PCOS are more likely to be overweight or obese, as well as insulin resistant. Further, PCOS is associated with high sympathetic nerve activity.

OBJECTIVE

To elucidate if self-reported hirsutism, body mass index (BMI) and waistline, circulating sex steroids, sex hormone-binding globulin (SHBG), insulin sensitivity and sympathetic nerve activity are associated with depression and anxiety-related symptoms in women with PCOS.

DESIGN AND METHODS

Seventy-two women with PCOS, aged 21-37 years, were recruited from the community. Hirsutism was self-reported using the Ferriman-Gallway score. Serum estrogens, sex steroid precursors, androgens and glucuronidated androgen metabolites were analyzed by gas and liquid chromatography/mass spectroscopy (GC-MS/LC-MS/MS) and SHBG by chemiluminiscent microparticle immunoassay (CMIA). Insulin sensitivity was measured with euglycemic hyperinsulinemic clamp. Sympathetic nerve activity was measured with microneurography. Symptoms of depression and anxiety were self-reported using the Montgomery Åsberg Depression Rating Scale (MADRS-S) and the Brief Scale for Anxiety (BSA-S).

RESULTS

Circulating concentrations of testosterone (T) (P=0.026), free T (FT) (P=0.025), and androstane-3α 17β-diol-3glucuronide (3G) (P=0.029) were lower in women with depression symptoms of potential clinical relevance (MADR-S≥11). The odds of having a MADRS-S score ≥11 were higher with lower FT and 3G. No associations with BSA-S were noted.

CONCLUSION

Lower circulating FT and 3G were associated with worse self-reported depression symptoms. The relationship between mental health, sex steroids and corresponding metabolites in PCOS requires further investigation.

Lifestyle changes in women with polycystic ovary syndrome

BACKGROUND

Polycystic ovary syndrome (PCOS) affects 4% to 18% of reproductive-aged women and is associated with reproductive, metabolic and psychological dysfunction. Obesity worsens the presentation of PCOS and weight management (weight loss, maintenance or prevention of excess weight gain) is proposed as an initial treatment strategy, best achieved through lifestyle changes incorporating diet, exercise and behavioural interventions.

OBJECTIVES

To assess the effectiveness of lifestyle treatment in improving reproductive, anthropometric (weight and body composition), metabolic and quality of life factors in PCOS.

SEARCH STRATEGY

Electronic databases (Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library), MEDLINE, EMBASE, PsycINFO, CINAHL, AMED) (date of last search 7/9/2010), controlled trials register, conference abstracts, relevant journals, reference lists of relevant papers and reviews and grey literature databases, with no language restrictions applied.

SELECTION CRITERIA

Randomised controlled trials comparing lifestyle treatment (diet, exercise, behavioural or combined treatments) to minimal or no treatment in women with PCOS.

DATA COLLECTION AND ANALYSIS

Two authors independently selected trials, assessed methodological quality and risk of bias and extracted data.

MAIN RESULTS

Six studies were included with n=164 participants. Three studies compared physical activity to minimal dietary and behavioural advice or no advice. Three studies compared combined dietary, exercise and behavioural interventions to minimal intervention. Risk of bias varied with 4/6 having adequate sequence generation and clinician or outcome assessor blinding and 3/6 having adequate allocation concealment, complete outcome data and being free of selective reporting.  There were no studies assessing the fertility primary outcomes of pregnancy, live birth and miscarriage and no data for meta-analysis on ovulation or menstrual regularity. Lifestyle intervention provided benefits when compared to minimal treatment for secondary reproductive, anthropometric and reproductive outcomes. These included endpoint values for total testosterone (mean difference (MD) -0.27 nmol/L, 95% confidence interval (CI) -0.46 to -0.09, P = 0.004), hirsutism or excess hair growth by the Ferriman-Gallwey score (MD -1.19, 95% CI -2.35 to -0.03, P = 0.04), weight (MD -3.47 kg, 95% CI -4.94 to -2.00, P < 0.00001), waist circumference (MD -1.95 cm, 95% CI -3.34 to -0.57, P = 0.006) and fasting insulin (MD -2.02 µU/mL, 95% CI -3.28 to -0.77, P = 0.002). There was no evidence of effect of lifestyle for body mass index, free androgen index, sex hormone binding globulin, glucose or cholesterol levels; and no data for quality of life, patient satisfaction or acne.

AUTHORS' CONCLUSIONS

Lifestyle intervention improves body composition, hyperandrogenism (high male hormones and clinical effects) and insulin resistance in women with PCOS. There was no evidence of effect for lifestyle intervention on improving glucose tolerance or lipid profiles and no literature assessing clinical reproductive outcomes, quality of life and treatment satisfaction.

Aromatase inhibitors for ovulation induction and ovarian stimulation

Aromatase inhibitors (AIs) were originally developed for the treatment of advanced breast cancer in postmenopausal women. Their use in reproductive medicine has been extensively studied in the past decade. We reviewed the current strategies for ovulation induction for anovulatory women, mostly women with polycystic ovarian syndrome (PCOS), and the scientific basis for use of AIs in reproductive medicine. The AI, letrozole, is effective in ovulation induction in women with PCOS resistant to clomifene citrate and ovarian stimulation for intrauterine insemination and in vitro fertilization (IVF). Letrozole is an attractive option with its oral route of administration, cost, safety profile and effectiveness in ovulation induction and ovarian stimulation. Letrozole has the potential to be the first-line treatment option for ovulation induction in PCOS women, while its use in ovarian stimulation for IVF deserves further study.

Physical activity in women with polycystic ovary syndrome: prevalence, predictors, and positive health associations

OBJECTIVE

The purpose of this study was to describe the prevalence and predictors of physical activity in women with polycystic ovary syndrome (PCOS) and to explore the potential health benefits that are associated with physical activity in this population.

STUDY DESIGN

This was a cross-sectional assessment of 150 women with PCOS. Active women (those who met Department of Health and Human Services [DHHS] guidelines for exercise) were compared with inactive women with regards to demographic and psychosocial variables and health characteristics.

RESULTS

Fifty-nine percent (88/150 women) met the DHHS guidelines for physical activity. Active women were more likely than inactive women to be nulliparous (64.1% vs 40.0%; P = .04) and white (71.6% vs 42.6%; P = .0004). Inactive women were more likely to have mild depression (adjusted odds ratio, 2.2; 95% confidence interval, 1.01-4.79; P = .048).

CONCLUSION

Women with PCOS who met the DHHS guidelines for physical activity were more likely to enjoy a variety of health benefits. Our findings identify several groups that are at risk for inadequate physical activity.

Is having polycystic ovary syndrome a predictor of poor psychological function including anxiety and depression?

BACKGROUND

The impact of metabolic and reproductive features of polycystic ovary syndrome (PCOS) compromises psychological functioning. We investigated factors associated with negative psychological functioning to determine whether they were predictive of anxiety and depression in PCOS.

METHODS

A cross-sectional study was performed by questionnaire in 177 women with PCOS (mean ± SD age 32.8 ± 7.8 years) and 109 healthy controls (mean age 41.9 ± 15.4 years). Main outcome measures were anxiety and depression, measured using the Hospital Anxiety Depression Scale (HADS) and Multidimensional Body-Self Relations Questionnaire (MBSRQ), respectively.

RESULTS

Women with PCOS, compared with control women, had a higher mean anxiety HADS score (9.5 ± 3.9 versus 6.5 ± 3.6; P < 0.001), a higher mean depression score (5.7 ± 3.7 versus 3.3 ± 3.1; P < 0.001) and more negative body image in 7 out of 10 subscales of the MBSRQ. Multivariate regression analysis in PCOS showed that anxiety was predicted by self-worth (P < 0.0001), health evaluation (P = 0.005), time taken to diagnose PCOS (P = 0.003) and age (P = 0.02), while in control women, anxiety was predicted by self-worth (P = 0.009), health evaluation (P = 0.001) and rural living (P = 0.03). Depression in PCOS was predicted by self-worth (P = 0.0004), quality of life (QOL) (P = 0.004), fitness orientation (P = 0.002), appearance evaluation (P = 0.001) and time to diagnosis (P = 0.03) and in women without PCOS, by self-worth (P < 0.0001), QOL (P < 0.0001), illness orientation (P = 0.001) and appearance orientation (P = 0.02).

CONCLUSIONS

Women with PCOS have increased anxiety, depression and negative body image compared with women without PCOS. In women with or without PCOS, body image and self-worth are predictors of both anxiety and depression, while QOL also predicts only depression. Time taken to diagnose PCOS is associated with poor psychological functioning.

Lifestyle changes in women with polycystic ovary syndrome

BACKGROUND

Polycystic ovary syndrome (PCOS) affects 4% to 18% of reproductive-aged women and is associated with reproductive, metabolic and psychological dysfunction. Obesity worsens the presentation of PCOS and weight management (weight loss, maintenance or prevention of excess weight gain) is proposed as an initial treatment strategy, best achieved through lifestyle changes incorporating diet, exercise and behavioural interventions.

OBJECTIVES

To assess the effectiveness of lifestyle treatment in improving reproductive, anthropometric (weight and body composition), metabolic and quality of life factors in PCOS.

SEARCH STRATEGY

Electronic databases (Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library), MEDLINE, EMBASE, PsycINFO, CINAHL, AMED), controlled trials register, conference abstracts, relevant journals, reference lists of relevant papers and reviews and grey literature databases, with no language restrictions applied.

SELECTION CRITERIA

Randomised controlled trials comparing lifestyle treatment (diet, exercise, behavioural or combined treatments) to minimal or no treatment in women with PCOS.

DATA COLLECTION AND ANALYSIS

Two authors independently selected trials, assessed methodological quality and risk of bias and extracted data.

MAIN RESULTS

Six studies were included. Three studies compared physical activity to minimal dietary and behavioural advice or no advice. Three studies compared combined dietary, exercise and behavioural interventions to minimal intervention. There were no studies assessing fertility primary outcomes and no data for meta-analysis on ovulation or menstrual regularity. For secondary outcomes, lifestyle intervention provided benefits when compared to minimal treatment for endpoint values for total testosterone (mean difference (MD) -0.27 nmol/L, 95% confidence interval (CI) -0.46 to -0.09, P = 0.004), hirsutism by the Ferriman-Gallwey score (MD -1.19, 95% CI -2.35 to -0.03, P = 0.04), weight (MD -3.47 kg, 95% CI -4.94 to -2.00, P < 0.00001), waist circumference (MD -1.95 cm, 95% CI -3.34 to -0.57, P = 0.006), waist to hip ratio (MD -0.04, 95% CI -0.07 to -0.00, P = 0.02), fasting insulin (MD -2.02 µU/mL, 95% CI -3.28 to -0.77, P = 0.002) and oral glucose tolerance test insulin (standardised mean difference -1.32, 95% CI -1.73 to -0.92, P < 0.00001) and per cent weight change (MD -7.00%, 95% CI -10.1 to -3.90, P < 0.00001). There was no evidence of effect of lifestyle for body mass index, free androgen index, sex hormone binding globulin, glucose or lipids; and no data for quality of life, patient satisfaction or acne.

AUTHORS' CONCLUSIONS

Lifestyle intervention improves body composition, hyperandrogenism (high male hormones and clinical effects) and insulin resistance in women with PCOS. There was no evidence of effect for lifestyle intervention on improving glucose tolerance or lipid profiles and no literature assessing clinical reproductive outcomes, quality of life and treatment satisfaction.

Polycystic Ovary Syndrome: Update on Treatment Options and Treatment Considerations for the Future

Polycystic ovary syndrome is an endocrine disorder characterized by insulin resistance, hyperandrogenemia, obesity, and inflammation, and is the most common cause of infertility. Women with PCOS are at higher risk than non-PCOS women for diabetes, cardiovascular disease, endometrial cancer, and psychiatric disorders. Because many abnormalities present in PCOS and symptoms vary considerably among PCOS women, treatment is guided by presentation and does not consist of simply one modality. Often, however, one type of medication can ameliorate more than one abnormality in PCOS. This review summarizes current research on several treatment modalities for PCOS, including drugs that are fairly well-established as efficacious and other agents that may prove efficacious in the future, with particular emphasis on the benefits and barriers of lifestyle change.
