Comparing body image dissatisfaction between pregnant women and non-pregnant women : a systematic review and meta-analysis

Body image dissatisfaction refers to negative thoughts and feelings individuals have towards their own body appearance and this is thought to be affected by the physiological changes that occur during pregnancy. There are two main conflicting theories as to the effect pregnancy has on body image dissatisfaction: 1) Pregnancy related changes are in direct conflict with social ideas of female beauty (e.g. weight gain) and so increase body image dissatisfaction; 2) Due to changes in expectations of bodily appearance during pregnancy, women are liberated from social ideals at this time and thus body image dissatisfaction would decrease. This study aimed to assess these theories by synthesising the current literature. Six databases were searched, and 2,017 study abstracts were screened based on strict inclusion and exclusion criteria. Following screening and quality assessment by two blind reviewers, 17 studies (comprising 17 effect sizes) were subject to full review and meta-analysis following PRISMA guidelines. These studies included cross-sectional, longitudinal and retrospective designs. Results varied with some studies showing women to feel more positive about their body during pregnancy, others showing a more negative body experience and yet others showing no statistical difference. Overall the analysis showed no statistical difference in body image dissatisfaction between pregnant women and non-pregnant women (p = 0.39). Any changes that do occur are heterogeneous and likely to be largely dependent on the individual experience as well as moderator variables and other factors such as differences in methodology of research studies. Studies in this field of research would benefit from more explicit and complete reporting of data and key variables, in order to allow early intervention for women who display body image dissatisfaction in pregnancy

Bonding with bump : Interoceptive sensibility moderates the relationship between pregnancy body satisfaction and antenatal attachment

PROBLEM: There is limited understanding and contradictory results regarding the contribution of the pregnant bodily experience to antenatal attachment. BACKGROUND: Antenatal attachment is an important aspect of pregnancy, which has been linked with positive maternal and infant outcomes. Given the profound physical process of pregnancy, it is likely that bodily experience is implicated in antenatal attachment, with research supporting the involvement of pregnancy body (dis)satisfaction. However, previous research reveals conflicting results and has only focused on exteroceptive bodily experience (appearance) rather than internal physiological sensations (interoception). AIM: To examine the relative contributions of both external and internal bodily experience in antenatal attachment. METHODS: This cross-sectional study collected online survey data from 159 pregnant participants with measures capturing interoceptive sensibility (subjective experience of interoception), pregnancy body dissatisfaction and antenatal attachment. FINDINGS: We replicated previous findings that pregnancy body dissatisfaction is related to antenatal attachment. However, the relationship between pregnancy body dissatisfaction and antenatal attachment was moderated by worry about interoceptive signals. The interoceptive construct of body trust was most strongly associated with antenatal attachment. DISCUSSION: The results suggest that interoception is important for antenatal attachment, particularly feelings of body trust. Moreover, for individuals who were less worried about bodily sensations, high levels of body dissatisfaction were associated with low attachment scores, whilst for those who were more concerned about these sensations, the relationship between body dissatisfaction and antenatal attachment was mitigated. CONCLUSION: The results suggest that focusing on internal sensations may be a protective strategy against pregnancy body dissatisfaction to strengthen maternal bonds

Association between anxiety symptoms and Alzheimer's disease biomarkers in cognitively healthy adults: A systematic review and meta-analysis

Objective: Anxiety has been identified as both a risk factor and prodromal symptom for Alzheimer's disease (AD) and related dementias, however, the underlying neurobiological correlates remain unknown. The aim of this systematic review and meta-analysis was to examine the association between anxiety symptoms and two defining markers of AD neuropathology: amyloid-beta (Aβ) and tau. Methods: Systematic literature searches were conducted across 5 databases. Studies investigating the relationship between anxiety and AD neuropathology (i.e., Aβ and/or tau) in cognitively healthy adults were eligible. Where possible, effect sizes were combined across studies, for Aβ and tau separately, using random-effects meta-analyses. Sensitivity analyses were performed to assess whether results differed according to anxiety type (i.e., state and trait) and biomarker assessment modality (i.e., positron emission tomography and cerebrospinal fluid). Results: Twenty-seven studies reporting data from 14 unique cohorts met eligibility criteria. Random-effects meta-analyses revealed no associations between self-reported anxiety symptoms and either Aβ (13 studies, Fisher's z = 0.02, 95% confidence interval [CI] -0.01–0.05, p = 0.194) or tau (4 studies, Fisher's z = 0.04, 95% CI -0.02–0.09, p = 0.235). Results remained unchanged across sensitivity analyses. Conclusions: In cognitively healthy adults, meta-analytic syntheses revealed no associations between anxiety symptoms and either Aβ or tau. There is a critical need, however, for larger studies with follow-up periods to examine the effect of anxiety symptom onset, severity, and chronicity on AD neuropathology. Additionally, further research investigating other potential neurobiological correlates is crucial to advance scientific understanding of the relationship between anxiety and dementia

Developing a new measure of retrospective body dissatisfaction:links to postnatal bonding and psychological well-being

BACKGROUND: Pregnancy is a transformative time for women and their bodies, and therefore thoughts and feelings about the body understandably change during this period. While previous research has established the impact of body dissatisfaction on factors like antenatal attachment and maternal mental health, there is a notable gap in understanding its long-term effects on postnatal factors. This is often due to high attrition rates in longitudinal studies. Using retrospective measures could address this issue, however a measure of retrospective pregnant body dissatisfaction has not yet been identified. AIMS: This paper aimed to create a retrospective measure of pregnancy body dissatisfaction by adapting a previously validated measure. It also aimed to investigate the relationship between retrospective accounts of body dissatisfaction during pregnancy and postnatal anxiety, depression, and bonding. METHOD: Cross-sectional online survey data was collected from women postnatally ( N  = 404). FINDINGS: An exploratory and confirmatory factor analysis identified a two-factor model of retrospective body dissatisfaction, adapted from the Body Understanding Measure for Pregnancy Scale, which was equivalent to two of the original subscales. Using this factor structure, linear regressions demonstrated that higher levels of retrospective pregnant body dissatisfaction were associated with elevated rates of postnatal anxiety and depression and lower bonding scores. CONCLUSIONS: This study successfully established a measure for assessing retrospective pregnant body dissatisfaction, potentially aiding future research. Additionally, it has highlighted the link between pregnant body dissatisfaction and postnatal levels of depression, anxiety, and bonding. Thus, improving the pregnant bodily experience may have the potential to enhance the postnatal experience

Associations Between Repetitive Negative Thinking and Objective and Subjective Sleep Health in Cognitively Healthy Older Adults

OBJECTIVE: Poor sleep and high levels of repetitive negative thinking (RNT), including future-directed (ie, worry) and past-directed (ie, brooding) negative thoughts, have been associated with markers of dementia risk. The relationship between RNT and sleep health in older adults is unknown. This study aimed to investigate this association and its specificities including multiple dimensions of objective and subjective sleep. METHODS: This study used a cross sectional quantitative design with baseline data from 127 cognitively healthy older adults (mean age 69.4 ± 3.8 years; 63% female) who took part in the Age-Well clinical trial, France. RNT (ie, worry and brooding) levels were measured using the Penn State Worry Questionnaire and the Rumination Response Scale (brooding subscale). Polysomnography was used to assess sleep objectively, and the Pittsburgh Sleep Quality Index and the St. Mary's Hospital Sleep Questionnaire were used to measure sleep subjectively. In primary analyses the associations between RNT and sleep (ie, objective sleep duration, fragmentation and efficiency and subjective sleep disturbance) were assessed via adjusted regressions. RESULTS: Higher levels of RNT were associated with poorer objective sleep efficiency (worry: β=-0.32, p<0.001; brooding: β=-0.26, p=0.002), but not objective sleep duration, fragmentation, or subjective sleep disturbance. Additional analyses, however, revealed differences in levels of worry between those with short, compared with typical and long objective sleep durations (p < 0.05). CONCLUSION: In cognitively healthy older adults, RNT was associated with sleep characteristics that have been implicated in increased dementia risk. It will take additional research to ascertain the causal link between RNT and sleep characteristics and how they ultimately relate to the risk of developing dementia

Investigating the long term effects of body satisfaction during pregnancy on mother-infant outcomes

Pregnancy is a time of great change for women and their bodies. Many of the bodily changes are conflicting with the social ideals of the appearance of the female body, leaving women pressured to maintain a socially desirable pregnant body shape (Hodgkinson et al. 2014). This is alongside competing sensations such as increased appetite to sustain the fetus and reduced physical activity due to fatigue and pain (Chien &amp; Ko, 2004; Vermani, Mittal, &amp; Weeks, 2010). These pressures can impact on how satisfied women are with their changing pregnant bodies (Kirk &amp; Preston, 2019). A recent poll of over 200,000 pregnant women by BabyCentre.com (2018) found that 72% of women were not happy with or had mixed feelings about their pregnant bodies. This highlights the need for a better understanding of the long term effects of body dissatisfaction during pregnancy on mother-infant outcomes. The propose project aims to fill an important gap in the research by looking at the long term effects of body satisfaction and interoceptive changes during pregnancy on mother-infant outcomes. It is hoped that this would result in a better understanding of how to support women and their babies in the long term and could inform early interventions during pregnancy. It would also contribute to a better awareness for those supporting pregnant women around how these bodily changes influence a mother’s bond with their new-born babies, and how they feel in themselves. A secondary aim within the proposed project is to investigate the effectiveness of certain interventions in improving outcomes for both mother and baby

The role of bodily experiences during pregnancy on mother and infant outcomes

Pregnancy is a transformative time for women and their bodies, and therefore thoughts and feelings and about one's own body and internal bodily sensations may understandably change during this period. Body satisfaction and interoception have been found to influence factors such as antenatal attachment (AA) and maternal mental health. However, mixed results in the literature suggest complex relationships between the bodily experience during pregnancy and outcomes, necessitating a broader investigative approach. We aim to examine the relationship between the pregnancy bodily experience and multiple mother-infant outcomes. It is hypothesised that poor bodily experiences during pregnancy will have negative impacts on these outcomes. Cross-sectional online survey data was collected from individuals at various gestations throughout pregnancy as part of a larger longitudinal study (N = 253, mean age = 32). We analysed validated measures of pregnancy body satisfaction, interoceptive sensibility, AA and mood, as well as intentions to breastfeed. Linear regressions were used to confirm findings from previous literature and a network analysis allowed for a more exploratory approach to understanding the importance of the bodily experience during pregnancy. Multiple regressions found low body satisfaction predicts higher levels of anxiety, depression and AA. A network analysis revealed relationships between body satisfaction and interoception during pregnancy and mother-infant outcomes, including depression and AA. Our results highlight the far-reaching effects of poor bodily experiences during pregnancy on a variety of outcomes. Understanding the impact of the pregnant bodily experience can help identify at-risk individuals and inform interventions

The effects of yoga-based interventions on postnatal mental health and well-being: A systematic review

Background: The postnatal period is a critical time for maternal mental health, presenting unique challenges and vulnerabilities. Identifying effective and accessible strategies to improve postnatal mental health and well-being is therefore crucial and could have substantial benefits for both mothers and babies, alongside broader implications for healthcare systems. Yoga is a potential intervention that has demonstrated notable benefits; however, a gap exists in systematically evaluating the existing literature on postnatal yoga-based interventions. This systematic review addresses this, aiming to comprehensively assess the impact of postnatal yoga on maternal mental health and well-being. Methods: Six databases were searched using keywords “yoga”, “yogic”, “postnatal”, “postpartum”, “perinatal”, “maternal”, “mother*“. Articles were considered if they were quantitative and evaluated a yoga or yoga-based intervention in postnatal samples. Study outcomes were extracted and synthesised descriptively. A quality assessment of studies was also conducted. Findings: Of the 383 non-duplicated records that were identified, nine met criteria for full-text review. Only 6 met the inclusion criteria and so were included in the review. Across the 6 studies within this review, data from 377 adult women were included and looked at the outcomes of women in the USA, Northern Ireland, Taiwan and Turkey. The findings of the studies suggest that taking part in postnatal yoga is associated with decreased symptoms of depression, an increase in psychological well-being and quality of life. Key conclusions: Yoga-based interventions may offer a promising and effective intervention for maternal mental health and well-being. However, due to the limited number of studies, and a lack of consistency in study design and measures, more high-quality research is required to establish these effects and explore the potential benefits on other aspects of maternal well-being and infant outcomes
