Obesity and anxiety during pregnancy and postpartum: A systematic review

BACKGROUNDnObesity and anxiety during the perinatal period are common and associated with poor health outcomes for the mother and the child. Despite the well-documented health risks of both pregnancy obesity and anxiety, associations between the two have rarely been explored. With this review we aim to provide a systematic overview of the current state of evidence concerning associations between ante- and postnatal anxiety and pregnancy obesity, excessive gestational weight gain, and postpartum weight retention.nnnMETHODSnWe conducted a systematic literature search in PubMed, Web of Science, and PsychINFO.nnnRESULTSn13 Records matched our inclusion criteria. Five out of seven studies focusing on pregnancy obesity and anxiety suggest a positive association with ante- or postnatal anxiety. Surprisingly, no study examined anxiety disorders according to DSM and it remains unknown whether anxiety symptomatology reaches clinical relevance. Results from a small number of life-style intervention studies (n=3) suggest that interventions could benefit from a stronger focus on mental health. There were not enough studies on associations between excessive gestational weight gain (n=2) or postpartum weight retention (n=3) and anxiety making it difficult to draw conclusions about possible associations.nnnLIMITATIONnThe number of included studies is rather small and studies were included irrespective of the study quality which might limit the generalizability of the results.nnnCONCLUSIONSnThe majority of the included studies suggest that obese pregnant women might constitute a subgroup that is especially vulnerable for comorbid anxiety and in need of targeted psychological support. However, further high-quality studies, particularly including anxiety disorders, are needed.

The German Version of the Dutch Eating Behavior Questionnaire: Psychometric Properties, Measurement Invariance, and Population-Based Norms

The Dutch Eating Behavior Questionnaire is an internationally widely used instrument assessing different eating styles that may contribute to weight gain and overweight: emotional eating, external eating, and restraint. This study aimed to evaluate the psychometric properties of the 30-item German version of the DEBQ including its measurement invariance across gender, age, and BMI-status in a representative German population sample. Furthermore, we examined the distribution of eating styles in the general population and provide population-based norms for DEBQ scales. A representative sample of the German general population (N = 2513, age ≥ 14 years) was assessed with the German version of the DEBQ along with information on sociodemographic characteristics and body weight and height. The German version of the DEQB demonstrates good item characteristics and reliability (restraint: α = .92, emotional eating: α = .94, external eating: α = .89). The 3-factor structure of the DEBQ could be replicated in exploratory and confirmatory factor analyses and results of multi-group confirmatory factor analyses supported its metric and scalar measurement invariance across gender, age, and BMI-status. External eating was the most prevalent eating style in the German general population. Women scored higher on emotional and restrained eating scales than men, and overweight individuals scored higher in all three eating styles compared to normal weight individuals. Small differences across age were found for external eating. Norms were provided according to gender, age, and BMI-status. Our findings suggest that the German version of the DEBQ has good reliability and construct validity, and is suitable to reliably measure eating styles across age, gender, and BMI-status. Furthermore, the results demonstrate a considerable variation of eating styles across gender and BMI-status.

Randomized Controlled Trial of an Internet-Based Cognitive-Behavioral Treatment Program for Binge-Eating Disorder☆

Binge-eating disorder (BED) is a prevalent health condition associated with obesity. Few people with BED receive appropriate treatment. Personal barriers include shame, fear of stigma, geographic distance to mental health services, and long wait-lists. The aims of this study were to examine the efficacy of an Internet-based cognitive-behavioral intervention for adults with threshold BED (DSM-IV) and to examine the stability of treatment effects over 12months. Participants were randomly assigned to a 16-week Internet-based cognitive-behavioral intervention (n=69) or a wait-list condition (n=70). Binge-eating frequency and eating disorder psychopathology were measured with the Eating Disorder Examination-Questionnaire and the Eating Disorder Examination administered over the telephone. Additionally, body weight and body mass index, depression, and anxiety were assessed before and immediately after treatment. Three-, 6-, and 12-month follow-up data were recorded in the treatment group. Immediately after the treatment the number of binge-eating episodes showed significant improvement (d=1.02, between group) in the treatment group relative to the wait-list condition. The treatment group had also significantly reduced symptoms of all eating psychopathology outcomes relative to the wait-list condition (0.82≤d≤1.11). In the treatment group significant improvement was still observed for all measures 1year after the intervention relative to pretreatment levels. The Internet-based intervention proved to be efficacious, significantly reducing the number of binge-eating episodes and eating disorder pathology long term. Low-threshold e-health interventions should be further evaluated to improve treatment access for patients suffering from BED.

Childhood maltreatment and pre-pregnancy obesity: a comparison of obese, overweight, and normal weight pregnant women

Pre-pregnancy overweight and obesity is associated with poor health outcomes for the mother and the child. General population studies suggest that childhood maltreatment is associated with obesity in adulthood. The aim of our study was to examine the association between pre-pregnancy overweight and obesity and a history of childhood abuse or neglect including different stages of severity of abuse and neglect. Three hundred twenty-six normal weight, overweight, or obese pregnant women reported demographic data, height and weight, and general psychological distress at 18–22xa0weeks of gestation. Childhood maltreatment was assessed using the Childhood Trauma Questionnaire. Associations were examined using logistic regression analyses and a reference group of normal weight women. Fifty percent reported a history of abuse or neglect. After adjusting for age, education, income, marital status, and the number of previous children, pre-pregnancy overweight and obesity were strongly associated with severe physical abuse (overweight: ORu2009=u20098.33, 95xa0% CI 1.48–47.03; obesity: ORu2009=u20096.31, 95xa0% CI 1.06–37.60). Women with severe physical neglect (ORu2009=u20094.25, 95xa0% CI 1.23–14.74) were at increased risk of pregnancy overweight. We found a dose-response relationship between physical abuse and pre-pregnancy overweight and obesity. Whereas other studies report an association between childhood maltreatment and pre-pregnancy obesity, this is the first study that found an association between childhood maltreatment and pre-pregnancy overweight. Considering the severe health risks of pre-pregnancy overweight and obesity and the long-term consequences of childhood maltreatment, affected women constitute a subgroup with special needs in prenatal care. Further research is needed to improve the understanding of the underlying mechanisms.

Verständlichkeit von Patientenschulungen in der orthopädischen Rehabilitation: Qualitative Erhebung bei Rehabilitanden und Schulungsleitern

STUDY OBJECTIVEnAn important requirement for achieving postulated goals in the context of patient education is that patient education be conducted in a way that the patients can understand it. It is the objective of this explorative study to examine how patients and providers evaluate the comprehensibility and patients comprehension of patient education under routine conditions during orthopaedic rehabilitation. Furthermore, we aim to explore the influencing factors that patients and providers describe as conducive and counterproductive to the comprehensibility of patient education, and the ideas or desires they have as to how patient education can be made more comprehensible.nnnMETHODSnWe conducted guided focus groups with 50 patients with chronic back pain or osteoarthritis aged between 22 and 71 years (M=50.4, SD=9.4) and 35 patient education providers aged between 26 and 61 years (M=44.9, SD=9.8) in a total of 9 orthopaedic rehabilitation centres. Qualitative analyses of the interview transcripts were conducted according to Mayrings content analytic approach using Atlas.ti software.nnnRESULTSnPatients and providers evaluate patient education as generally comprehensible. The involvement of patients in patient education is reported by both patients and providers as the main conducive factor. Patients describe poor (e. g. superficial or contradictory) information as counterproductive regarding comprehensibility, while providers tend to mention patients lack of motivation and of taking personal responsibility as hindering patients comprehension. Patients and providers proposals and ideas can be organized in the topics patient education (e. g. stronger reference to patients everyday life), providers (e. g. improving providers tutoring skills), information (e. g. more information), patient involvement (e. g. stronger consideration of patients interests), organization (e. g. smaller groups), and goal clarification (e. g. consideration of patients expectations).nnnCONCLUSIONnOur results reveal that good comprehensibility can be achieved in patient education during routine orthopaedic rehabilitation. They also show the factors that account for good comprehensibility. The counterproductive factors described by patients and providers provide evidence of the factors that may hold potential for improving patient education with regard to comprehensibility.

Antenatal and postnatal depression in women with obesity: a systematic review

Obesity and depression are prevalent complications during pregnancy and associated with severe health risks for the mother and the child. The co-occurrence of both conditions may lead to a particular high-risk group. This review provides a systematic overview of the association between pre-pregnancy obesity and antenatal or postnatal depression. We conducted a systematic electronic literature search for English language articles published between January 1990 and March 2017. Inclusion criteria were (a) adult pregnant women, (b) women with pre-pregnancy obesity and normal weight controls, (c) definition of obesity according to the IOM 1990/2009 criteria, (d) established depression measure, and (e) report on the association between pre-pregnancy obesity and antenatal or postnatal depression. Fourteen (eight prospective (PS), six cross-sectional (CS)) studies were included. One study reported data from a large community-based sample, and one reported cross-national data. Of 13 studies examining pre-pregnancy obesity and antenatal depression, 9 found a higher risk or higher levels of antenatal depression among women with obesity relative to normal weight (6 PS, 3 CS), while 4 studies found no association (2 PS, 2 CS). Of four studies examining pre-pregnancy obesity and postnatal depression, two studies found a positive association (two PS), one study (CS) reported different findings for different obesity classes, and one study found none (PS). The findings suggest that women with obesity are especially vulnerable to antenatal depression. There is a need to develop appropriate screening routines and targeted interventions to mitigate negative health consequences for the mother and the child. Research addressing the association between obesity and postnatal depression is too limited to draw solid conclusions. Results are mainly based on selective samples, and there is a need for further high-quality prospective studies examining the association between pre-pregnancy obesity and antenatal and postnatal depression.

„Aktiv in der Reha“: Entwicklung und formative Evaluation einer Patientenschulung zur Förderung der Gesundheitskompetenz von chronisch Kranken

OBJECTIVEnThe aim of the article is to describe the development, the process of manualisation and results from the formative evaluation of a patient-oriented patient education program to increase health literacy of patients with chronic illness (Active in rehab).nnnMETHODSnThemes of the patient education program were extracted from 17 focus groups. An expert meeting was conducted to validate the content of the patient education program. The formative evaluation was based on a questionnaire (N(max) = 295 patients and N(max) = 39 trainers).nnnRESULTSnThe patient education program includes 4 modules with 3 themes (bio-psycho-social model, rehabilitation goals, communication competencies). The evaluation of the modules was good to very good. An analysis of free texts and a follow-up survey among trainers helped us to infer important improvements to the patient education program.nnnCONCLUSIONnRESULTS from the formative evaluation show that the patient education program meets patients and trainers needs and is accepted.

Grief interventions for people bereaved by suicide: A systematic review

Background Adaption to the loss of a loved one due to suicide can be complicated by feelings of guilt, shame, responsibility, rejection, and stigmatization. Therefore people bereaved by suicide have an increased risk for developing complicated grief which is related to negative physical and mental disorders and an increased risk for suicidal behavior. Grief interventions are needed for this vulnerable population. The aim of this systematic review was to provide an overview of the current state of evidence concerning the effectiveness of interventions that focus on grief for people bereaved by suicide. Methods We conducted a systematic literature search using PubMed, Web of Science, and PsycINFO for articles published up until November 2016. Relevant papers were identified and methodological quality was assessed by independent raters. A narrative synthesis was conducted. Results Seven intervention studies met the inclusion criteria. Two interventions were based on cognitive-behavioral approaches, four consisted of bereavement groups, and one utilized writing therapy. As five of the seven interventions were effective in reducing grief intensity on at least one outcome measure, there is some evidence that they are beneficial. Bereavement groups tend to be effective in lowering the intensity of uncomplicated grief, as are writing interventions in lowering suicide-specific aspects of grief. Cognitive-behavioral programs were helpful for a subpopulation of people who had high levels of suicidal ideation. Limitation On average, methodological quality was low so the evidence for benefits is not robust. The stability of treatment effects could not be determined as follow-up assessments are rare. Generalizability is limited due to homogeneous enrollments of mainly female, white, middle-aged individuals. Conclusions People bereaved by suicide are especially vulnerable to developing complicated grief. Therefore, grief therapies should be adapted to and evaluated in this population. Prevention of complicated grief may be successful in populations of high risk individuals.

Predictors of Changes in Health-Related Quality of Life 6 and 12 months After a Bariatric Procedure

BackgroundBariatric surgery is an effective method for treating morbid obesity and improving patientsʼ health-related quality of life (HRQoL). As research on predictors that contribute to the amelioration of HRQoL is sparse, our prospective study was conducted to examine the predictive value of demographic, psychological and physiological variables on physical and mental HRQoL 6 and 12xa0months after surgery.MethodsWe surveyed 154 participants who had undergone either a laparoscopic Roux-en-Y gastric bypass (LRYGB) or a laparoscopic sleeve gastrectomy (LSG). Prior to surgery and both 6 and 12xa0months after the procedure, patients completed questionnaires concerning their demographic data, height and weight, co-morbid conditions, HRQoL (Short Form Health Survey-12), depression severity (Beck Depression Inventory-II), and eating psychopathology (Eating Disorder Examination-Questionnaire). Multiple linear regression analyses were conducted to detect predictors of physical and mental HRQoL 6 and 12xa0months post-operation.ResultsThe predictors included within the models explained 50 to 58% of the variance of post-operative physical and mental HRQoL, respectively. Higher baseline depression severity was associated with reduced HRQoL after surgery, whereas changes from pre- to post-surgery in BDI-II scores positively predicted HRQoL values, especially mental HRQoL. The persistence of somatic co-morbid disorders had a negative effect on physical HRQoL.ConclusionsDepression severity before surgery and changes in depression scores were found to be major predictors of HRQoL after bariatric surgery. Therefore, we recommend screening patients regularly for depression both before and after bariatric surgery and offering them adequate psychotherapeutic and/or psychopharmacologic support.

Associations of childhood maltreatment with pre-pregnancy obesity and maternal postpartum mental health: a cross-sectional study

BackgroundPre-pregnancy obesity and postpartum mental disorders are prevalent health risks to both the mother and the offspring. The objective of our study was to examine whether a history of childhood maltreatment is associated with pre-pregnancy obesity and postpartum mental health and whether childhood maltreatment and pre-pregnancy BMI independently predict postpartum mental health.MethodsWe obtained self-reported data from 741 postpartum women before 16xa0weeks after delivery (Mu2009=u20098.1xa0weeks, SDu2009=u20093.2). Childhood sexual, physical, and emotional abuse and physical and emotional neglect were assessed with the Childhood Trauma Questionnaire. Depression and anxiety were assessed using the BDI and SCL-90-R. We conducted logistic regression models adjusted for demographic covariates and co-occurrence of different types of maltreatment.Results7.6% of the included women entered pregnancy with obesity. Forty-six percent reported any type of childhood maltreatment. 6.4% displayed at least moderate postnatal depressive symptomatology and 20.5% scored above the 75th percentile for postpartum anxiety. Severe physical abuse, moderate emotional abuse and severe physical and emotional neglect were associated with pre-pregnancy obesity. After controlling for the presence of all other types of childhood maltreatment, only severe physical abuse was still predictive for pre-pregnancy obesity (adj.ORu2009=u20095.24, 95% CIu2009=u20091.15-23.75). Pre-pregnancy obesity was associated with an increased risk of postpartum depression (adj.ORu2009=u20092.55, 95% CIu2009=u20091.08-6.00) but not with elevated anxiety. Pre-pregnancy obesity and severe childhood sexual abuse independently predicted postpartum depression. After controlling for histories of different types of childhood maltreatment, the association between pre-pregnancy obesity and postpartum depression attenuated to non-significance.ConclusionsTo our knowledge, this is the first study examining empirical relations between childhood maltreatment, pre-pregnancy BMI and postpartum mental health controlling for the co-occurrence of other maltreatment types. Childhood maltreatment has been found being associated with both pre-pregnancy obesity and impaired postpartum mental health and may at least partly account for the association between pre-pregnancy obesity and postpartum depression. Therefore childhood maltreatment is related to two common risk conditions during pregnancy and postpartum which bear several health risks for the mother and the child, and routine screening for histories of childhood maltreatment among pregnant women is warranted.
