Polycystic ovary syndrome: a complex condition with psychological, reproductive and metabolic manifestations that impacts on health across the lifespan

Polycystic ovary syndrome (PCOS) is of clinical and public health importance as it is very common, affecting up to one in five women of reproductive age. It has significant and diverse clinical implications including reproductive (infertility, hyperandrogenism, hirsutism), metabolic (insulin resistance, impaired glucose tolerance, type 2 diabetes mellitus, adverse cardiovascular risk profiles) and psychological features (increased anxiety, depression and worsened quality of life). Polycystic ovary syndrome is a heterogeneous condition and, as such, clinical and research agendas are broad and involve many disciplines. The phenotype varies widely depending on life stage, genotype, ethnicity and environmental factors including lifestyle and bodyweight. Importantly, PCOS has unique interactions with the ever increasing obesity prevalence worldwide as obesity-induced insulin resistance significantly exacerbates all the features of PCOS. Furthermore, it has clinical implications across the lifespan and is relevant to related family members with an increased risk for metabolic conditions reported in first-degree relatives. Therapy should focus on both the short and long-term reproductive, metabolic and psychological features. Given the aetiological role of insulin resistance and the impact of obesity on both hyperinsulinaemia and hyperandrogenism, multidisciplinary lifestyle improvement aimed at normalising insulin resistance, improving androgen status and aiding weight management is recognised as a crucial initial treatment strategy. Modest weight loss of 5% to 10% of initial body weight has been demonstrated to improve many of the features of PCOS. Management should focus on support, education, addressing psychological factors and strongly emphasising healthy lifestyle with targeted medical therapy as required. Monitoring and management of long-term metabolic complications is also an important part of routine clinical care. Comprehensive evidence-based guidelines are needed to aid early diagnosis, appropriate investigation, regular screening and treatment of this common condition. Whilst reproductive features of PCOS are well recognised and are covered here, this review focuses primarily on the less appreciated cardiometabolic and psychological features of PCOS.

The effects of gender and age on health related behaviors

BackgroundLifestyle-related diseases, including diabetes, cardiovascular disease, and some cancers represent the greatest global health threat. Greater insight into health needs and beliefs, using broad community samples, is vital to reduce the burden of chronic disease. This study aimed to investigate gender, age, screening practices, health beliefs, and perceived future health needs for healthy ageing.MethodsRandom probability sampling using self-completion surveys in 1456 adults residing in Australia.ResultsScreening behaviors were associated with gender and age. Men and women >51 years were more likely (27%) to have screening health checks than those <50 years (2%). Factors nominated to influence health were lifestyle (92%), relationships (82%), and environment (80%). Women were more likely to nominate preparedness to have an annual health check, willingness to seek advice from their medical practitioner and to attend education sessions. Numerous health fears were associated with ageing, however participants were more likely to have a financial (72%) rather than a health plan (42%). More women and participants >51 years wanted information regarding illness prevention than men or those aged <30 years.ConclusionAge and gender are associated with health related behaviors. Optimal health is perceived as a priority, yet often this perception is not translated into preventative action. These findings will inform future research and policy makers as we strive towards a healthier ageing society and the prevention of chronic disease.

Anxiety and depression in polycystic ovary syndrome: a comprehensive investigation

Polycystic ovary syndrome (PCOS) is associated with high levels of depression, which impact quality of life and limit self-efficacy, yet less is known about prevalence of anxiety. This cross-sectional, observational study of community-based women with PCOS comprehensively examined mood and found that anxiety existed at higher levels than depression, anxiety was underdiagnosed, and more women with PCOS who reported infertility were depressed.

A low intensity, community based lifestyle programme to prevent weight gain in women with young children: cluster randomised controlled trial

Objective To develop and evaluate the effectiveness of a community behavioural intervention to prevent weight gain and improve health related behaviours in women with young children. Design Cluster randomised controlled trial. Setting A community setting in urban Australia. Participants 250 adult women with a mean age of 40.39 years (SD 4.77, range 25-51) and a mean body mass index of 27.82 kg/m2 (SD 5.42, range 18-47) were recruited as clusters through 12 primary (elementary) schools. Intervention Schools were randomly assigned to the intervention or the control. Mothers whose schools fell in the intervention group (n=127) attended four interactive group sessions that involved simple health messages, behaviour change strategies, and group discussion, and received monthly support using mobile telephone text messages for 12 months. The control group (n=123) attended one non-interactive information session based on population dietary and physical activity guidelines. Main outcome measures The main outcome measures were weight change and difference in weight change between the intervention group and the control group at 12 months. Secondary outcomes were changes in serum concentrations of fasting lipids and glucose, and changes in dietary behaviours, physical activity, and self management behaviours. Results All analyses were adjusted for baseline values and the possible clustering effect. Women in the control group gained weight over the 12 month study period (0.83 kg, 95% confidence interval (CI) 0.12 to 1.54), whereas those in the intervention group lost weight (−0.20 kg, −0.90 to 0.49). The difference in weight change between the intervention group and the control group at 12 months was −1.13 kg (−2.03 to −0.24 kg; P<0.05) on the basis of observed values and −1.11 kg (−2.17 to −0.04) after multiple imputation to account for possible bias created by missing values. Secondary analyses after multiple imputation showed a difference in the intervention group compared with the control group for total cholesterol concentration (−0.35 mmol/l, −0.70 to −0.001), self management behaviours (diet score 0.18, 0.13 to 0.33; physical activity score 0.24, 0.05 to 0.43), and confidence to control weight (0.40, 0.11 to 0.69). Regular self weighing was associated with weight loss in the intervention group only (−1.98 kg, −3.75 to −0.23). Conclusions Weight gain in women with young children could be prevented using a low intensity self management intervention delivered in a community setting. Self management of health behaviours improved with the intervention. The response rate of 12%, although comparable with that in other community studies, might limit the ability to generalise to other populations.

A systematic review of interventions aimed at the prevention of weight gain in adults.

OBJECTIVE The WHO has recommended that prevention of overweight and obesity should begin early and target adults, including those with an acceptable BMI. The aim of the present paper was to systematically review published interventions with a specific stated aim to prevent weight gain. DESIGN Five databases were searched to July 2008. The reference lists of review articles and obesity society meetings abstracts were hand searched. Interventions were included if the primary aim was to prevent weight gain and they included a comparison group. RESULTS Ten publications were included, describing nine separate interventions in adults of various ages and target populations. All interventions incorporated diet and physical activity with behaviour change strategies. Most studies were between 1 and 3 years in duration. Five studies reported a significant difference in weight between intervention and control subjects of between 1.0 and 3.5 kg, due largely to an increase in weight in the control group. However, there was a lack of consistent, clear, psychological models and a failure to identify successful components. More intensive interventions were not always successful, nor were mail-only or clinic-based interventions. In contrast, interventions that included mixed modes of delivery with some personal contact were successful. CONCLUSIONS There were relatively few trials aimed at the prevention of weight gain. Existing trials varied by intensity, delivery methods, target groups and study components, and therefore provide limited opportunities for comparison of effect size. Further large, effective, evidence-based programmes are urgently needed in the general population as well as high-risk groups.

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.

Obesity, metabolic complications and the menopause: an opportunity for prevention

The prevalence of obesity is rising dramatically, impacting adversely on health and well-being at the menopause and across the lifespan. With menopause, abdominal adiposity selectively increases. The impact of obesity and abdominal adiposity on chronic disease, including diabetes and cardiovascular disease, is significant and quality of life is adversely affected. Yet accurate perception of the weight-related health-risk profile is lacking and there is inadequate focus on prevention and treatment of obesity and its complications. Research aimed at prevention and management of obesity at menopause is limited. Accurate risk perception, education and translation programs highlighting obesity risks and supporting sustainable lifestyle changes are needed, particularly around menopause.

Weight, physical activity and dietary behavior change in young mothers: short term results of the HeLP-her cluster randomized controlled trial.

BackgroundPreventing weight gain rather than treating established obesity is an important economic and public health response to the rapidly increasing rates of obesity worldwide. Treatment of established obesity is complex and costly requiring multiple resources. Preventing weight gain potentially requires fewer resources to reach broad population groups, yet there is little evidence for successful interventions to prevent weight gain in the community. Women with children are an important target group because of high rates of weight gain and the potential to influence the health behaviors in family members.MethodsThe aim of this cluster randomized controlled trial was to evaluate the short term effect of a community-based self-management intervention to prevent weight gain. Two hundred and fifty mothers of young children (mean age 40 years ± 4.5, BMI 27.9 kg/m2± 5.6) were recruited from the community in Melbourne, Australia. The intervention group (n = 127) attended four interactive group sessions over 4 months, held in 12 local primary schools in 2006, and was compared to a group (n = 123) receiving a single, non-interactive, health education session. Data collection included self-reported weight (both groups), measured weight (intervention only), self-efficacy, dietary intake and physical activity.ResultsMean measured weight decreased significantly in the intervention group (-0.78 kg 95% CI; -1.22 to -0.34, p < 0.001). Comparing groups using self-reported weight, both the intervention and comparison groups decreased weight, -0.75 kg (95% CI; -1.57 to 0.07, p = 0.07) and -0.72 kg (95% CI; -1.59 to 0.14 p = 0.10) respectively with no significant difference between groups (-0.03 kg, 95% CI; -1.32 to 1.26, p = 0.95). More women lost or maintained weight in the intervention group. The intervention group tended to have the greatest effect in those who were overweight at baseline and in those who weighed themselves regularly. Intervention women who rarely self-weighed gained weight (+0.07 kg) and regular self-weighers lost weight (-1.66 kg) a difference of -1.73 kg (95% CI; -3.35 to -0.11 p = 0.04). The intervention reported increased physical activity although the difference between groups did not reach significance. Both groups reported replacing high fat foods with low fat alternatives and self-efficacy deteriorated in the comparison group only.ConclusionBoth a single health education session and interactive behavioral intervention will result in a similar weight loss in the short term, although more participants in the interactive intervention lost or maintained weight. There were small non-significant changes to physical activity and changes to fat intake specifically replacing high fat foods with low fat alternatives such as fruit and vegetables. Self-monitoring appears to enhance weight loss when part of an intervention.Trial registrationACTRN12608000110381

Polycystic ovary syndrome: a biopsychosocial understanding in young women to improve knowledge and treatment options.

Aim. To assess psychological features in young women with and without PCOS. Methods. Observational, cross-sectional pilot study in young women aged 18–25 with (n = 24) or without (n = 22) PCOS (age: 22.41 ± 0.39 vs. 21.95 ± 0.47 years, p = 0.46; BMI: 29.17 ± 1.54 vs. 22.05 ± 0.83 kg/m2, p = 0.0003). The main outcome measures were quality of life, anxiety, depression, risk perception and fears on future health. Results. Women with PCOS demonstrated worsened quality of life (p = 0.033) and greater anxiety (p = 0.01) and depression (p = 0.023) than women without PCOS related to BMI status. Women with PCOS were more likely to perceive themselves as at risk of obesity (p = 0.012) and infertility (p < 0.0001), and perceived greater importance in reducing future risk of prediabetes (p = 0.027), gestational diabetes (p = 0.039), type 2 diabetes (p = 0.01), heart disease (p = 0.005), obesity (p = 0.0007) and infertility (p = 0.023) than women without PCOS. Women with PCOS were more likely to have fears about future health related to weight gain (p = 0.045), loss of femininity (p = 0.035), loss of sexuality (p = 0.003) and infertility (p = 0.019) than women without PCOS. Conclusions. Worsened quality of life, anxiety and depression in young women with PCOS is related to BMI. Risk perception is appropriately high in PCOS, yet perceived risks of future metabolic complications are less common than those related to weight gain and infertility.
