A three-component cognitive behavioural lifestyle program for preconceptional weight-loss in women with polycystic ovary syndrome (PCOS): a protocol for a randomized controlled trial

Background

Obesity in women with polycystic ovary syndrome (PCOS) negatively affects all clinical features, and a 5 to 10% weight loss has shown promising results on reproductive, metabolic and psychological level. Incorporating a healthy diet, increasing physical activity and changing dysfunctional thought patterns in women with PCOS are key points in losing weight. The biggest challenge in weight management programs is to achieve a reasonable and sustainable weight loss. The aim of this study is to explore whether Cognitive Behavioural Therapy (CBT) by a mental health professional, working in a multidisciplinary team with a dietician and a physical therapist (a three-component intervention), is more effective for weight loss in the long term, within 12 months. We will also explore whether mobile phone applications are effective in supporting behavioural change and sustainable weight loss.

Methods

The present study is a longitudinal randomized controlled trial (RCT) to study the effectiveness of a three-component 1-year cognitive-behavioural lifestyle intervention in overweight/obese women with PCOS. A total of 210 participants are randomly assigned to three groups: 1) CBT provided by the multidisciplinary team or; 2) CBT provided by the multidisciplinary team and Short Message Service (SMS) or; 3) usual care: encourage weight loss through publicly available services (control group). The primary aim of the 12-month intervention is to explore whether a three-component 1-year cognitive-behavioural lifestyle intervention is effective to decrease weight, when compared to usual care. Secondary outcomes include: the effect of the intervention on the PCOS phenotype, waist circumference, waist to hip ratio, ovulation rates, total testosterone, SHBG, free androgen index (FAI), AMH, hirsutism, acne, fasting glucose, blood pressure and all psychological parameters. Additionally, we assessed time to pregnancy, ongoing pregnancies, clinical pregnancies, miscarriages and birth weight.

All outcome variables are measured at the start of the study, and again at 3 months, 6 months, nine months and 12 months.

Discussion

We expect that CBT provided by a multidisciplinary team, especially combined with SMS, is effective in developing a healthy lifestyle and achieving a long-term weight loss in women with PCOS. Losing 5– 10% body weight improves various PCOS characteristics. Consequently, we expect to show that CBT provided by a multidisciplinary team improves reproductive and metabolic outcomes, as well as quality of life, while at the same time being cost-effective.

ESHRE guideline: routine psychosocial care in infertility and medically assisted reproduction-a guide for fertility staff

STUDY QUESTION

Based on the best available evidence in the literature, what is the optimal management of routine psychosocial care at infertility and medically assisted reproduction (MAR) clinics?

SUMMARY ANSWER

Using the structured methodology of the Manual for the European Society of Human Reproduction and Embryology (ESHRE) Guideline Development, 120 recommendations were formulated that answered the 12 key questions on optimal management of routine psychosocial care by all fertility staff.

WHAT IS ALREADY KNOWN

The 2002 ESHRE Guidelines for counselling in infertility has been a reference point for best psychosocial care in infertility for years, but this guideline needed updating and did not focus on routine psychosocial care that can be delivered by all fertility staff.

STUDY, DESIGN, SIZE, DURATION

This guideline was produced by a group of experts in the field according to the 12-step process described in the ESHRE Manual for Guideline Development. After scoping the guideline and listing a set of 12 key questions in PICO (Patient, Intervention, Comparison and Outcome) format, thorough systematic searches of the literature were conducted; evidence from papers published until April 2014 was collected, evaluated for quality and analysed. A summary of evidence was written in a reply to each of the key questions and used as the basis for recommendations, which were defined by consensus within the guideline development group (GDG). Patient and additional clinical input was collected during the scoping and the review phase of the guideline development.

PARTICIPANTS/MATERIALS, SETTING, METHODS

The guideline group, comprising psychologists, two medical doctors, a midwife, a patient representative and a methodological expert, met three times to discuss evidence and reach consensus on the recommendations.

MAIN RESULTS AND THE ROLE OF CHANCE THE GUIDELINE PROVIDES

120 recommendations that aim at guiding fertility clinic staff in providing optimal evidence-based routine psychosocial care to patients dealing with infertility and MAR. The guideline is written in two sections. The first section describes patients' preferences regarding the psychosocial care they would like to receive at clinics and how this care is associated with their well-being. The second section of the guideline provides information about the psychosocial needs patients experience across their treatment pathway (before, during and after treatment) and how fertility clinic staff can detect and address these. Needs refer to conditions assumed necessary for patients to have a healthy experience of the fertility treatment. Needs can be behavioural (lifestyle, exercise, nutrition and compliance), relational (relationship with partner if there is one, family friends and larger network, and work), emotional (well-being, e.g. anxiety, depression and quality of life) and cognitive (treatment concerns and knowledge).

LIMITATIONS, REASONS FOR CAUTION

We identified many areas in care for which robust evidence was lacking. Gaps in evidence were addressed by formulating good practice points, based on the expert opinion of the GDG, but it is critical for such recommendations to be empirically validated.

WIDER IMPLICATIONS OF THE FINDINGS

The evidence presented in this guideline shows that providing routine psychosocial care is associated with or has potential to reduce stress and concerns about medical procedures and improve lifestyle outcomes, fertility-related knowledge, patient well-being and compliance with treatment. As only 45 (36.0%) of the 125 recommendations were based on high-quality evidence, the guideline group formulated recommendations to guide future research with the aim of increasing the body of evidence.

Bullying, abuse and family conflict as risk factors for chronic pain among Dutch adolescents

PURPOSE

Psychosocial stress seems to serve as an important risk factor for the occurrence of pain. The present study aims to examine if early adversities, e.g. bullying, abuse and family conflict are risk factors for chronic pain in adolescents. The secondary aim of the present study was to describe the pain characteristics of chronic pain in adolescents in a community sample of Dutch adolescents.

METHODS

Participants in the present study were 15,220 adolescents, attending schools (grade 7 and 8) in Rotterdam, the Netherlands. Chronic pain was measured with a newly developed questionnaire; the Pain Barometer. Early adversities were measured using single-item questions from the Rotterdam Youth Monitor, a longitudinal youth health surveillance system. Cross-sectional associations between early adversities and chronic pain were investigated using logistic multilevel analysis, adjusted for potential confounding.

RESULTS

In school year 2010-2011, 9.2% of the 15,220 adolescents reported chronic pain. Physical abuse by others (OR = 1.51, 95% CI =  1.07-2.14), sexual abuse (OR = 1.46, 95% CI = 1.05-2.05), family conflict (OR = 1.79, 95% C = 1.61-1.99) and being bullied (OR = 1.23, 95% CI = 1.17-1.29) are more common in adolescents with chronic pain. Physical abuse (OR = 1.28, 95% CI = 0.95-1.71) by parents and parental divorce (OR = 1.07, 95% CI = 0.93-1.22) were not significantly related to chronic pain.

CONCLUSIONS

The results of the present study suggest that bullying, abuse and family conflict may be risk factors for chronic pain in adolescents. Early signalling these stressors might prevent chronic pain.

IMPLICATIONS AND CONTRIBUTION

Early adversities, i.e. physical and sexual abuse, being bullied and family conflict, might be risk factors for developing chronic pain. In addition, the present study suggests that chronic pain is common among Dutch adolescents and interferes with their daily activities. If future studies confirm our results, this knowledge can be used to improve the signalling and prevention of chronic pain in adolescents.

The effect of a short message service maintenance treatment on body mass index and psychological well-being in overweight and obese children: a randomized controlled trial

OBJECTIVE

Maintaining weight loss results in childhood obesity treatment is difficult to achieve. Self-management techniques such as self-monitoring are associated with increased weight loss and maintenance. This study analyzes whether self-monitoring of lifestyle behaviours through a short message service maintenance treatment (SMSMT) via mobile phones with personalized feedback positively effects weight, lifestyle behaviours and psychological well-being in obese children.

METHODS

After 3 months of behavioural lifestyle treatment, 141 overweight and obese children (7-12 years) were randomly assigned to an intervention group receiving SMSMT for 9 months (n = 73) or to the control group (n = 68). The intervention group sent weekly self-monitoring data on exercise and eating behaviour and their mood via mobile phones. In return, they received tailored feedback messages. Primary treatment outcomes were weight, eating behaviour and psychological well-being, i.e. competence, self-esteem and quality of life. Secondary outcome was adherence to the SMSMT. Data were analyzed with mixed modelling.

RESULTS

SMSMT did not improve treatment outcomes. Controls gained temporarily in physical health scores (P = 0.01). SMSMT completers sent on average every 2 weeks an SMS. Children who had greater weight loss during the first 3 months of lifestyle treatment sent more SMSs (P = 0.04).

CONCLUSIONS

We did not find a positive effect of SMSMT on weight, eating behaviour or psychological well-being in obese children. SMSMT seems to be a feasible method of treatment delivery. Future research should study variations of SMSMT to investigate how SMSMT can be more effective.

Why do couples drop-out from IVF treatment? A prospective cohort study

BACKGROUND

Cumulative IVF pregnancy rates are compromised by the large number of couples who drop-out of treatment before achieving pregnancy. The aim of this study was to identify the role of the treatment strategy applied, and potential other factors that influence the decision of couples to discontinue treatment.

METHODS

The incidence of drop-out from IVF treatment and factors related to drop-out were studied in a cohort of IVF patients aged <38 years embarking on IVF treatment either with a mild or a standard treatment strategy for a planned maximum number of treatment cycles.

RESULTS

Of the 384 couples studied, 17% dropped out of IVF treatment. The physical or psychological burden of treatment was the most frequent cause of drop-out (28%). The application of a mild treatment strategy (mild ovarian stimulation along with the transfer of a single embryo) significantly reduced the chance of drop-out (hazard ratio (HR) 0.55; 95% confidence interval (CI), 0.31-0.96). When a mild IVF strategy was employed, the association between the baseline anxiety score and drop-out was reduced by >50%. The presence of severe male subfertility (HR 4.80; 95% CI, 1.63-14.13) and the failure to achieve embryo transfer (odds ratio 0.41; 95% CI, 0.24-0.72) were also related to drop-out.

CONCLUSIONS

Reducing drop-out rate is crucial to further improve the efficacy and cost-effectiveness of IVF treatment. An important factor determining the risk of drop-out is the burden of the treatment strategy. The application of a mild treatment strategy and managing patient's expectations might reduce drop-out rates.

[Reduction of patient discomfort, risks and costs, but not pregnancies, by a mild strategy for in-vitro fertilisation]

OBJECTIVE

To compare a so-called mild in-vitro fertilisation (IVF) treatment strategy with the standard IVF treatment on the following aspects: the chance of a pregnancy resulting in full-term live birth within 1 year, patient discomfort, multiple pregnancies, and costs.

DESIGN

Randomised, open-label, prospective trial (www.controlledtrials.com, number ISRCTN35766970).

METHOD

404 patients were assigned to undergo either a mild treatment, consisting of ovarian stimulation with a gonadotrophin releasing hormone (GnRH) antagonist combined with single embryo transfer, or the standard treatment consisting of prolonged stimulation with a GnRH agonist combined with the transfer of two embryos. The primary outcome measures were: (1) the percentage of cumulative pregnancies within one year after randomisation leading to full-term live birth; (2) total costs per couple and child up to 6 weeks after expected delivery; and (3) overall patient discomfort. Analysis was done according to the intention-to-treat principle and was intended to show that the mild treatment was not inferior to the standard treatment; the non-inferiority threshold was -12.5%.

RESULTS

The proportion of cumulative pregnancies resulting in full-term live birth after 1 year was 43.4% in the mild and 44.7% in the standard treatment group. The lower limit of the one-sided 95% confidence interval was equal to -9.8%. The respective proportion of couples with multiple pregnancies was 0.5% versus 13.1% (p < 0.0001), and the average total costs were Euro 8,333.- versus Euro 10,745.- (difference: Euro 2,412.-, 95% CI: 703-4,131). There were no statistically significant differences between the groups with regard to anxiety, depression, physical discomfort, and sleep quality.

CONCLUSION

After 1 year of treatment, the cumulative percentage of pregnancies leading to full-term live birth and the total patient discomfort were the same for the mild treatment (average 2.3 IVF-cycles) and the standard treatment (average 1.7 IVF-cycles). The mild treatment significantly reduced the number of multiple pregnancies and the overall costs.

Low negative affect prior to treatment is associated with a decreased chance of live birth from a first IVF cycle

BACKGROUND

Psychological variables, such as anxiety and depression, may have a negative impact on IVF outcomes, but the evidence remains inconclusive. Previous studies have usually measured a single psychological parameter with clinical pregnancy as the outcome. The objective of the current study was to determine whether pretreatment or procedural psychological variables in women undergoing a first IVF cycle affect the chance of achieving a live birth from that cycle.

METHODS

Between February 2002 and February 2004, 391 women with an indication for IVF were recruited at two University Medical Centres in The Netherlands. Pretreatment anxiety and depression were measured with the Hospital Anxiety and Depression Scale. The Daily Record Keeping Chart was used to measure negative and positive affect before treatment and daily during ovarian stimulation. Multiple stepwise forward logistic regression analysis was performed with term live birth as the dependent variable.

RESULTS

Regression analysis showed that women who expressed less negative affect at baseline were less likely to achieve live birth (P = 0.03). After one IVF cycle, women who received a standard IVF strategy were more likely to reach live birth delivery than those who received a mild IVF strategy (P = 0.002). A male/female indication for IVF was associated with a higher chance of achieving term live birth than a female only indication (P = 0.03). Age, duration of infertility or type of infertility were not independent predictors of live birth.

CONCLUSIONS

The relationship between psychological parameters and IVF success rates is more complex than commonly believed. The expression of negative emotions before starting IVF might not be always detrimental for outcomes.

The psychological impact of IVF failure after two or more cycles of IVF with a mild versus standard treatment strategy

BACKGROUND

Failure of IVF treatment after a number of cycles can be devastating for couples. Although mild IVF strategies reduce the psychological burden of treatment, failure may cause feelings of regret that a more aggressive approach, including the transfer of two embryos, was not employed. In this study, the impact of treatment failure after two or more cycles on stress was studied, following treatment with a mild versus a standard treatment strategy.

METHODS

Randomized controlled two-centre trial (ISRCTN35766970). Women were randomized to undergo mild ovarian stimulation (including GnRH antagonist co-treatment) and single embryo transfer (n = 197) or standard GnRH agonist long-protocol ovarian stimulation with double embryo transfer (n = 194). Participants completed the Hospital Anxiety and Depression Scale prior to commencing treatment and 1 week after the outcome of their final treatment cycle was known. Data from women who underwent two or more IVF cycles were subject to analysis (n = 253).

RESULTS

Women who experienced treatment failure after standard IVF treatment presented more symptoms of depression 1 week after treatment termination compared with women who had undergone mild IVF: adjusted mean (+/-95% confidence interval) = 10.2 (+/-2.3) versus 5.4 (+/-1.8), respectively, P = 0.01.

CONCLUSIONS

Failure of IVF treatment after a mild treatment strategy may result in fewer short-term symptoms of depression as compared to failure after a standard treatment strategy. These findings may further encourage the application of mild IVF treatment strategies in clinical practice.

The psychological impact of mild ovarian stimulation combined with single embryo transfer compared with conventional IVF

BACKGROUND

The objective of this study was to assess the psychological implications of mild ovarian stimulation combined with single embryo transfer (SET) during a first IVF cycle.

METHODS

We conducted a randomized controlled two-centre trial. Three hundred and ninety-one couples were randomized to undergo either mild ovarian stimulation with GnRH antagonist co-treatment and SET (n=199) or conventional GnRH agonist long protocol ovarian stimulation with double embryo transfer (DET) (n=192). Women completed the Hospital Anxiety and Depression Scale, the Hopkins Symptom Checklist and the Subjective Sleep Quality Scale at baseline, on the first day of ovarian stimulation and following embryo transfer. Affect was assessed daily with the Daily Record Keeping Chart from the first day of ovarian stimulation until the day treatment outcome became known.

RESULTS

The conventional IVF group experienced elevated levels of physical and depressive symptoms during pituitary downregulation. At oocyte retrieval, this group experienced more positive affect and less negative affect than the mild IVF group. In the conventional IVF group, cycle cancellation was associated with less positive and more negative affect.

CONCLUSIONS

During the first IVF treatment cycle, mild ovarian stimulation and SET does not lead to more psychological complaints than conventional IVF.

Comparison of different treatment strategies in IVF with cumulative live birth over a given period of time as the primary end-point: methodological considerations on a randomized controlled non-inferiority trial

BACKGROUND

We discuss methodological considerations related to a study in IVF, which compares the effectiveness, health economics and patient discomfort of two treatment strategies that differ in both ovarian stimulation and embryo transfer policies.

METHODS

This was a randomized controlled clinical trial in two large Dutch IVF centres. The tested treatment strategies are: mild ovarian stimulation [including gonadotrophin-releasing hormone (GnRH) antagonist co-treatment] together with the transfer of one embryo, versus conventional stimulation (with GnRH agonist long protocol co-treatment) and the transfer of two embryos. Outcome measures are: (i) pregnancies resulting in term live birth; (ii) total costs per term live birth; and (iii) patient stress/discomfort per started IVF treatment, over a 12 month period. Power considerations for this study were an overall cumulative live birth rate of 45% for the conventional treatment strategy, with non-inferiority of the mild treatment strategy defined as a live birth rate no more than 12.5% lower compared with the conventional study arm. For a power of 80% and alpha of 0.05, 400 subjects are required.

RESULTS

As planned, from February 2002 until February 2004, 410 patients were enrolled.

CONCLUSIONS

This effectiveness study applies an integrated medical, health economics and psychological approach with term live birth over a given period of time after starting IVF as the end-point. Complete and timely patient enrolment vindicates many of the design decisions.

Effectiveness of a psychosocial counselling intervention for first-time IVF couples: a randomized controlled trial

BACKGROUND

The objective of this study was to evaluate a psychosocial counselling intervention for first-time IVF couples. In this article the results on women's distress are presented.

METHODS

Two hundred sixty-five couples admitted to an IVF treatment programme at the Erasmus MC were asked to participate in this study. Eighty-four couples agreed and were randomized according to a computer-generated random-numbers table into either a routine-care control group or an intervention group. The intervention consisted of three sessions with a social worker trained in Experiential Psychosocial Therapy: one before, one during and one after the first IVF cycle. Distress was measured daily during treatment by the Daily Record Keeping Chart. Depression and anxiety were measured before and after treatment by the Hospital Anxiety and Depression Scale.

RESULTS

No significant group differences were found.

CONCLUSIONS

The results of this study do not support the implementation of our counselling intervention for all first-time IVF couples. The low response rate suggests that there is little perceived need for psychosocial counselling among couples during a first IVF treatment cycle.

Perceptions and knowledge about the acquired immunodeficiency syndrome among students in university residences

Using an anonymous questionnaire to obtain baseline data on sexual behaviour and knowledge of the acquired immunodeficiency syndrome (AIDS) among students in university residences, the following information was obtained: Knowledge of AIDS was found to be high, although misconceptions regarding transmission of the virus were prevalent. Mosquito bites (15%) and the donating of blood (31%) were incorrectly identified as methods of transmission of the virus. Deep kissing was recognised by only 27% of the students as a possible method of transmission while 22% and 13% of the students, respectively, failed to identify the sharing of razor blades and blood transfusions as possible means of contracting HIV infection. The students' knowledge had not greatly affected sexual behaviour. Two-thirds of the respondents had previously had sexual contact; 38% were sexually active at the time of the study, and of these 74% had engaged in unprotected intercourse with casual partners in the previous 6 months. There was a negative attitude towards condom use and over 80% of sexually active students did not perceive themselves to be at risk of contracting AIDS. Campus Health (82%), State health services (51%), and public advertisements (60%) were preferred sources of AIDS information. Newspapers/magazines (80%) and leaflets (69%) were identified as the preferred media. In reality, significantly fewer students obtained their information from Campus Health (15%; P less than 0.05), State health services (19%, P less than 0.05) and leaflets (44%; P less than 0.05). It can be concluded that education programmes should be developed by credible organisations to ensure that an awareness of AIDS results in appropriate sexual behaviour.
