The well-being of bereaved parents in an only-child society

Relationship between Perceived Family Resilience, Emotional Flexibility, and Anxiety Symptoms: a Parent-Adolescent Dyadic Perspective

Family resilience is crucial for individual's psychological health. Previous studies explored the protective factors of anxiety at the individual level, with less attention paid to the impact of family interaction from a dyadic perspective. This study utilized the Actor-Partner Interdependence Mediation Model to investigate the relationship between family resilience, emotional flexibility, and anxiety symptoms. A sample of 2144 Chinese parent-adolescent dyads (36% upper grades of primary school, 64% secondary school, 49.39% girls; 70.38% mothers) was recruited. Perceived family resilience was inversely related to anxiety symptoms, directly or indirectly, through the mediation of emotional flexibility at the individual level. At the dyadic level, adolescents' perceived family resilience was significantly associated with parents' anxiety symptoms through their own or parents' emotional flexibility. Parents' perceived family resilience was inversely link to adolescents' anxiety symptoms through parents' emotional flexibility. Parents emotional flexibility also mediated the association between adolescents' perceived family resilience and their anxiety symptoms. These findings contribute to understanding the intricate dynamics of family resilience and psychological outcomes in parent-child relationships under adversity, emphasizing the need for child-centered interventions to improve family members' mental health.

Does Interpersonal Vulnerability Mediate the Association Between Parental Bereavement and Mental Health?

The current study examined the role of interpersonal vulnerability, that is, self-perceived threats to one's interpersonal domain, in the mental health of bereaved parents. Israeli bereaved parents in older adulthood (N = 105, aged 48-88, M = 64.06, SD = 9.93) were pair-matched with equivalent 105 non-bereaved parents. Participants completed questionnaires assessing interpersonal vulnerability, satisfaction with life, and depressive symptoms. The results showed higher levels of interpersonal vulnerability among bereaved parents compared to their non-bereaved counterparts. Additionally, parental bereavement and interpersonal vulnerability were associated with worse mental health. Finally, interpersonal vulnerability mediated the association of parental bereavement with worse mental health. This study reveals interpersonal vulnerability as an important vulnerability factor among a significant minority in older adulthood.

Social disabling: A qualitative study of interpersonal interaction patterns of shiduers in China

The experience of shidu (i.e., losing one's only child) completely changes the lives and social interaction patterns of people. However, current research findings on interpersonal interactions of individuals who are experiencing shidu (referred to as "shiduers") are inconsistent, reducing the effectiveness of support programs. Therefore, a qualitative analysis was conducted on the interpersonal interaction process of shiduers using the classic grounded theory. The results showed that "shidu" as an interpersonal information has two contradictory attributes, "family shame" and "family routine," which create a social disabling dilemma for shiduers. Shiduers can reset their interpersonal relationships by establishing a clear inner and outer circle of relationships (centralizing) and by sequencing and typing relationships (differentiating). The interpersonal interactions of shiduers are complex and depend on the type of relationship. The current results can help community workers target individual support, family empowerment, and community building for people experiencing shidu.

Disorganized Functional Connectivity of Anterior Insular Subnetworks in Adults with Executive Dysfunction after Trauma Exposure

There is increasing evidence that major trauma can adversely affect the brain and cognition. In some cases, trauma may lead to deficits in executive function (EF). The anterior insula may be a causal outflow hub acting to coordinate EF-related brain networks. To clarify the neural underpinnings of EF deficits (EFD) after trauma, we performed a resting-state functional magnetic resonance imaging (rs-fMRI) study of anterior insular subnetworks in adults who have lost their only child. A total of 167 participants completed various psychological and cognitive assessments to assess EF-related deficits. Correlations were computed between abnormal connectivity and cognitive/post-traumatic stress symptoms. The results showed abnormal anterior insular subregion connectivity in the default mode network (DMN), prefrontal lobe, and cerebellum lobe in participants with EFD. No correlation was found between abnormal connectivity and cognitive/post-traumatic stress symptoms in participants with EFD. These results suggest that excessive connections between the insula and DMN could contribute to EFD after trauma. Overall, this study provides novel references into the neural mechanisms of EF status after trauma exposure.

Relationship between SLC6A2 gene polymorphisms and brain volume in Han Chinese adults who lost their sole child

BACKGROUND

Norepinephrine transporter (NET) is encoded by the SLC6A2 gene and is a potential target for studying the pathogenesis of PTSD. To the best of our knowledge, no prior investigations have examined SLC6A2 polymorphism-related neuroimaging abnormalities in PTSD patients.

METHODS

In 218 Han Chinese adults who had lost their sole child, we investigated the association between the T-182 C SLC6A2 genotype and gray matter volume (GMV). Participants included 57 PTSD sufferers and 161 non-PTSD sufferers, and each group was further separated into three subgroups based on each participant's SLC6A2 genotype (TT, CT, and CC). All participants received magnetic resonance imaging (MRI) and clinical evaluation. To assess the effects of PTSD diagnosis, genotype, and genotype × diagnosis interaction on GMV, 2 × 3 full factorial designs were used. Pearson's correlations were used to examine the association between GMV and CAPS, HAMD, and HAMA.

RESULTS

The SLC6A2 genotype showed significant main effects on GMV of the left superior parietal gyrus (SPG) and the bilateral middle cingulate gyrus (MCG). Additionally, impacts of the SLC6A2 genotype-diagnosis interaction were discovered in the left superior frontal gyrus (SFG). The CAPS, HAMA, and HAMD scores, as well as the genotype main effect and diagnostic SLC6A2 interaction, did not significantly correlate with each other.

CONCLUSION

These findings indicate a modulatory effect that the SLC6A2 polymorphism exerts on the SPG and MCG, irrespective of PTSD diagnosis. We found evidence to suggest that the SLC6A2 genotype-diagnosis interaction on SFG may potentially contribute to PTSD pathogenesis in adults who lost their sole child.

The relationship between perceived stress and prolonged grief disorder among Chinese Shidu parents: effects of anxiety and social support

BACKGROUND

Shidu parents refer to the couple who have lost their only child and have not given birth or adopted another child in China. The number of Shidu parents is increasing annually. The aim of this research was to examine the mediating role of anxiety and the moderating role of social support between perceived stress and prolonged grief disorder (PGD) among Chinese Shidu parents.

METHODS

A cross-sectional study was carried out with 505 participants who completed a questionnaire including the Prolonged Grief Questionnair-3 (PG-13), the Perceived Stress Scale-10 (PSS-10), the Self-Rating Anxiety Scale (SAS) and the Duke-UNC Functional Social Support Questionnaire (FSSQ). SPSS PROCESS macro was employed to examine the mediating role of anxiety and the moderating role of social support.

RESULTS

The mediation analysis showed anxiety partially mediated the link between perceived stress and PGD, and the proportion of mediation of anxiety was 39.22%. The moderated mediation analysis revealed the second stage of mediating effects of anxiety on the link between perceived stress and PGD was moderated by social support. Specifically, compared with Shidu parents with higher social support, the association between anxiety and PGD was closer for those with lower social support.

CONCLUSIONS

The moderated mediation model can broaden our understanding of how and when perceived stress, anxiety and social support work together to affect PGD. The interventions aimed at improving mental health of Chinese Shidu parents need to work on reducing stress and enhancing social support.

Altered brain degree centrality and functional connectivity in adults with executive dysfunction after trauma exposure

Losing an only child is undoubtedly a huge blow that can adversely affect the prefrontal lobe, a highly sensitive brain region. Neuropsychological evidence emphasizes that executive function (EF) is closely related to the optimal functioning of the frontal cortex. However, the characteristics and potential mechanisms underlying changes in executive function following the huge shock of losing an only child remain insufficiently studied and understood. In this study, we performed degree centrality (DC) and functional connectivity (FC) analyses to explore the organization of the executive function deficits (EFD) network among adults who have lost their only child. In addition, we performed correlation analyses to establish an association between abnormal DC and FC values and post-traumatic stress symptoms. Finally, we used support vector machine analyses to assess the accuracy of abnormal DC and FC values in distinguishing adults with EFD who have lost their only child from those without EFD. Our findings revealed increased DC in the left superior frontal gyrus and right angular gyrus (ANG), whereas decreased DC in the left superior occipital gyrus among adults with EFD. Further FC analysis revealed that the altered FC primarily involved the prefrontal and temporal lobes and cerebellum. Notably, the altered FC between the right ANG and left inferior temporal gyrus exhibited a negative correlation with irritability symptoms (R = -0.047, p = 0.003) in the EFD group. A combined model incorporating altered DC and FC values enabled the classification of 96.69% of adults with EFD, with a sensitivity of 0.8837 and specificity of 0.9558. These findings provide valuable insights into the neural mechanisms underlying distinct EF statuses following trauma exposure, distinguishing adults with and without EFD.

Persistence of post-traumatic stress disorder in Chinese Shidu parents is associated with combined gray and white matter abnormalities

Post-traumatic stress disorder (PTSD) is one of the most common mental health disorders among Shidu parents. Identification of gray and white matter differences between persistence of PTSD (P-PTSD) and remission of PTSD (R-PTSD) is crucial to determine their prognosis. A total of 37 Shidu parents with PTSD were followed for five years. Surface-based morphometry and diffusion tensor imaging were carried out to analyze the differences in gray and white matter between P-PTSD and R-PTSD. Finally, 30 patients with PTSD were enrolled, including 12 with P-PTSD and 18 with R-PTSD. Compared with patients with R-PTSD, patients with P-PTSD exhibited lower fractional anisotropy (FA) in Cluster 1 (including body of the corpus callosum, superior longitudinal fasciculus, corticospinal tract) and Cluster 2 (including inferior fronto-occipital fasciculus, inferior longitudinal fasciculus, splenium of the corpus callosum) in the left cerebral hemisphere and higher cortical thickness in the right lateral occipital cortex (LOC). In patients with P-PTSD, FA values of Cluster 2 were negatively correlated with cortical thickness of the right LOC. These results suggest that among Shidu parents, differences were observed in gray and white matter between P-PTSD and R-PTSD. Moreover, some certain gray and white matter abnormalities were often present simultaneously in P-PTSD.

Time course of attentional bias and its relationship with PTSD symptoms in bereaved Chinese parents who have lost their only child

Background: The death of a child is a highly traumatic event for parents and often leads to posttraumatic stress disorder (PTSD). Attentional bias has been demonstrated in the onset and maintenance of PTSD symptoms.Objective: This study aimed to investigate the time course of attentional bias among bereaved Chinese parents who have lost their only child (Shidu parents), and to examine its relationship with PTSD symptoms and symptom clusters.Methods: Shidu parents (n = 38; 50-72 years of age) completed a dot-probe task with negative (trauma-related), positive, and neutral images at four stimulus presentation times (250, 500, 750, and 1250 ms). PTSD symptoms were measured by the PTSD Checklist for DSM-5 (PCL-5).Results: We observed difficulty in disengaging from both negative and positive stimuli at 750 ms and attentional bias away from negative stimuli at 1250 ms. At 1250 ms, attentional avoidance of trauma-related stimuli was positively correlated with PCL-5 total and intrusion scores. Difficulty in disengaging from positive stimuli was negatively correlated with PCL-5 total and intrusion scores as well as negative alterations in cogniti and mood scores.Conclusions: These findings enhance our understanding of attentional bias and cognitive-affective processing in PTSD. This study provides evidence that attentional bias (difficulty in disengaging from positive stimuli and bias away from negative stimuli) are correlated with PTSD symptoms and certain symptom clusters.

Extending the Ring Theory of Personhood to the Care of Dying Patients in Intensive Care Units

It is evident, in the face of the COVID-19 pandemic that has physicians confronting death and dying at unprecedented levels along with growing data suggesting that physicians who care for dying patients face complex emotional, psychological and behavioural effects, that there is a need for their better understanding and the implementation of supportive measures. Taking into account data positing that effects of caring for dying patients may impact a physician's concept of personhood, or "what makes you, 'you'", we adopt Radha Krishna's Ring Theory of Personhood (RToP) to scrutinise the experiences of physicians working in intensive care units (ICU) using a fictional scenario that was inspired by real events. The impact of death and dying, its catalysts, internal constituents, external factors, dyssynchrony, and buffers, specific to ICU physicians, were identified and explored. Such a framework allows for ramifications to be considered holistically and facilitates the curation of strategies for conflict resolution. This evaluation of the RToP acknowledges the experience and wide-ranging effects it has on ICU physicians. As such, our findings provide insight into their specific needs and highlight the importance of support on a personal and organisational level. Although further research needs to be conducted, the RToP could serve as the basis for a longitudinal assessment tool supported by the use of portfolios or mentorship due to their provision of personalised, appropriate, specific, timely, accessible and long-term support.

Symptom structure of posttraumatic stress disorder after parental bereavement - a network analysis of Chinese parents who have lost their only child

BACKGROUND

The death of a child is a highly traumatic event and often leads to mental health problems, including posttraumatic stress disorder (PTSD). Previous studies have focused on overall PTSD after the loss of an only child; however, little attention has been given to PTSD at the symptom level. This study aims to identify the network structure of PTSD symptoms in bereaved parents who have lost their only child, known as Shidu parents in Chinese society.

METHODS

A cross-sectional study enrolled 385 bereaved individuals who had lost an only child across 10 cities in China from November 2016 to July 2017. PTSD symptoms were measured by the PTSD Checklist for DSM-5 (PCL-5). Network analysis was implemented by using the R packages qgraph and bootnet.

RESULTS

The PTSD network revealed that diminished interest, exaggerated startle, irritability/anger, and nightmares were the most central symptoms. The strongest connections emerged between the symptoms of recurrent thoughts and nightmares, irritability/anger and reckless/self-destructive behavior, and hypervigilance and exaggerated startle.

LIMITATIONS

We utilized cross-sectional data, and it is therefore not possible to infer the evolution of the symptom network over time. In addition, participants were limited to parents who had lost an only child, and the findings of this study must be interpreted with caution.

CONCLUSIONS

The current study provides further clarity regarding how PTSD symptoms relate to each other in bereaved parents who have lost an only child. Symptoms with high centrality and connectedness may be viable targets for intervention in bereaved parents who have lost an only child.

Parental bereavement - impact of death of neonates and children under 12 years on personhood of parents: a systematic scoping review

BACKGROUND

Losing a child tragically impacts the well-being and functioning of parents. With these effects extending beyond emotional, physical morbidity and compromising self-perceptions, appropriate, longitudinal, timely and personalised support is key to effective care of bereaved parents. However, in the absence of a comprehensive understanding of parental bereavement, effective support of bereaved parents remains suboptimal. To address this gap, we scrutinise prevailing data on the effects of a child's death, aged 0-12 years, through the lens of the Ring Theory of Personhood (RToP).

METHODS

To study prevailing accounts of bereaved parents following the death of a child, we adopt Krishna's Systematic Evidence Based Approach (SEBA) to structure our Systematic Scoping Review (SSR in SEBA).

RESULTS

Three thousand seventy-four abstracts were reviewed, 160 full text articles were evaluated, and 111 articles were included and analysed using thematic and content analysis. Four themes/categories were identified relating to the four rings of the RToP. Findings reveal that static concepts of protective and risk factors for grief are misplaced and that the support of healthcare professionals is key to assisting bereaved parents.

CONCLUSION

In the absence of consistent support of bereaved parents, this study highlights the need for effective training of healthcare professionals, beginning with an appreciation that every aspect of an individual parent's personhood is impacted by the loss of their child. Acknowledging grief as a complex, evolving and personalised process subjected to parental characteristics, settings, context and available support, this SSR in SEBA calls attention to effective nurturing of the relationship between parents and healthcare professionals, and suggests use of the RToP to assess and direct personalised, timely, specific support of parents in evolving conditions. We believe the findings of this review also call for further studies to support healthcare professionals as they journey with bereaved parents.

Maternal depression and loss of children under the one-child family planning policy in China: a cross-sectional study of 300 000 women

OBJECTIVES

This study aims to explore the association between maternal depression and the loss of the only child under the family-planning (FP) policy.

DESIGN

Cross-sectional data from a Chinese population-based study were analysed.

SETTING

Population from 10 (5 rural and 5 urban) areas in China.

PARTICIPANTS

Around 300 000 females were included in the study. The FP group was defined as women with one or two live births. Those with no surviving child were classified into the loss-of-only-child group. The non-FP group included women who had more than two live births. Logistic regression was used to assess the relationship between major depressive disorder (MDD) and family types, after stratification and adjustment.

OUTCOME

MDD was assessed using the Composite International Diagnostic Inventory.

RESULTS

The odds of MDD are 1.42 times higher in the FP group in general (OR=1.42, 95% CI: 1.28 to 1.57), as opposed to the non-FP group. In particular, the odds of MDD are 1.36 times greater in the non-loss-of-only-child group (OR=1.36, 95% CI: 1.21 to 1.51) and 2.80 (OR=2.80, 95% CI: 0.88 to 8.94) times greater in the loss-of-only-child group, compared with the non-FP group. The associations between FP groups and MDD appeared to be stronger in the elderly population, in those who were married, less educated and those with a higher household income. The association was found progressively stronger in those who lost their only child.

CONCLUSIONS

People in the FP group, especially those who lost their only child, are more susceptible to MDD than their counterparts in the non-FP group. Mental health programmes should give special care to those who lost their only child and take existing social policies and norms, such as FP policies, into consideration.

Decreased functional connectivity of hippocampal subregions and methylation of the NR3C1 gene in Han Chinese adults who lost their only child

BACKGROUND

Losing one's only child is a major traumatic life event that may lead to post-traumatic stress disorder (PTSD); however, the underlying mechanisms of its psychological consequences remain poorly understood. Here, we investigated subregional hippocampal functional connectivity (FC) networks based on resting-state functional magnetic resonance imaging and the deoxyribonucleic acid methylation of the human glucocorticoid receptor gene (NR3C1) in adults who had lost their only child.

METHODS

A total of 144 Han Chinese adults who had lost their only child (51 adults with PTSD and 93 non-PTSD adults [trauma-exposed controls]) and 50 controls without trauma exposure were included in this fMRI study (age: 40-67 years). FCs between hippocampal subdivisions (four regions in each hemisphere: cornu ammonis1 [CA1], CA2, CA3, and dentate gyrus [DG]) and methylation levels of the NR3C1 gene were compared among the three groups.

RESULTS

Trauma-exposed adults, regardless of PTSD diagnosis, had weaker positive FC between the left hippocampal CA1, left DG, and the posterior cingulate cortex, and weaker negative FC between the right CA1, right DG, and several frontal gyri, relative to healthy controls. Compared to non-PTSD adults, PTSD adults showed decreased negative FC between the right CA1 region and the right middle/inferior frontal gyri (MFG/IFG), and decreased negative FC between the right DG and the right superior frontal gyrus and left MFG. Both trauma-exposed groups showed lower methylation levels of the NR3C1 gene.

CONCLUSIONS

Adults who had lost their only child may experience disrupted hippocampal network connectivity and NR3C1 methylation status, regardless of whether they have developed PTSD.

Prevalence and risk factors of posttraumatic stress disorder among Chinese shidu parents: A systemic review and meta-analysis

BACKGROUND

Losing the only child is an extremely distressful life event for parents. Previous studies indicated that shidu parents were more vulnerable to develop posttraumatic stress disorder (PTSD). This study aims to calculate the pooled prevalence of PTSD and identify its risk factors.

METHOD

We conducted a systematic literature search in PubMed, Web of Science, Embase, China National Knowledge Infrastructure (CNKI), Wanfang databases, Vip databases. We performed a meta-analysis using random effects models to calculate the pooled PTSD in shidu parents. Associated factors for PTSD was evaluated by determining standardized mean difference (SMD) with 95% CIs. All analyses were performed using the Stata 16.0.

RESULTS

Eight articles (covering 2,722 shidu parents) were included in this study. The pooled prevalence of PTSD was 46.8% (95%CI: 33.2%-60.3%) among Chinese shidu parents. Female (SMD[95%CI]: 0.41[0.20, 0.62]), higher education level (SMD[95%CI]: 0.15[0.03, 0.28]), lower income (SMD[95%CI]: 0.33[0.13, 0.53]), losing a daughter (SMD[95%CI]: 0.16[0.03, 0.28]) and shorter time since loss (SMD[95%CI]: 0.24[0.07, 0.40]) were significantly associated with a higher PTSD prevalence. Registered residence, cause of death, age of the child, and having a grandchild were not associated with PTSD.

LIMITATIONS

Some variables included in this meta-analysis were only measured twice, which limited the conclusions to some extent.

CONCLUSION

This meta-analysis indicated that nearly half of shidu parents experienced PTSD and provided evidence of risk factors for PTSD in shidu parents. Further research is suggested to determine how these factors interact. Effective interventions should be conducted to shidu parents with PTSD.

Loneliness Trajectories: Evidence for Staged Intervention Among Chinese Bereaved Parents

Losing an only child affects the mental health of many older adults in China, placing them at a higher risk of loneliness. However, few studies explore the long-term effects of losing an only child on loneliness trajectories among older Chinese bereaved parents. Adopting a qualitative, grounded theory approach, this study investigates how experiences of loneliness among bereaved parents evolve and the implications for staged intervention. Twenty-seven in-depth interviews were conducted with people who lost their only child in Shanghai and Wuhan. A multistep data analysis technique was used to analyze the data. The findings indicate that trajectories of perceived loneliness have three distinct stages and follow a U-shape in their frequency and intensity. Interventions of psychological consultation, social network restoration, and improved old-age support should be emphasized at each stage.

Parents' Experiences of Caring for Their Only Child With Mental Illness in China: A Qualitative Study

The current study explored Chinese parents' experiences of caring for their only child with mental illness. Face-to-face interviews with semi-structured questions were conducted to learn about the care experiences of parents whose only child had mental illness. Purposeful sampling was used to recruit parents (n = 14) and thematic analysis was used. Five themes were identified: (1) Having Responsibility to Care for Children, (2) Feeling Guilt and Self-Blame, (3) Experiencing Loneliness and Helplessness, (4) Drained by Caregiving, and (5) Worrying About the Future. Parents who cared for their only child with mental illness experienced considerable emotional and physical challenges. Professionals and health care providers should recognize and understand the experiences of these parents to identity their needs and provide adequate support. Targeted support services and appropriate professional information should be developed and provided for parents to relieve them of negative caregiving experiences and improve their psychological and physical well-being.

Grief and Posttraumatic Growth Among Chinese Bereaved Parents Who Lost Their Only Child: The Moderating Role of Interpersonal Loss

Objective: Losing the only child is considered as the most severe kind of bereavement. It can trigger intense grief symptoms along with loss of psychosocial resources, but meanwhile, it can also lead to posttraumatic growth (PTG). The current study aimed to examine (a) whether a curvilinear relationship exists between grief and PTG and (b) the moderating role of resources-loss among Chinese bereaved parents who lost their only child (shidu parents). Methods: One hundred and ninety-nine shidu parents from five provinces completed the assessment packet covering prolonged grief symptoms and PTG, as well as resource loss. Hierarchical regression analyses were computed to examine the curvilinear relationship and the moderating effect of interpersonal loss and socio-economic loss. Results: There was no significant curvilinear relationship between grief and PTG in shidu parents. Under the high levels of interpersonal loss, shidu parents' PTG scores decreased as the severity of grief increased. However, the socio-economic loss did not show a significant moderating effect. Conclusion: The results of the current study did not show a significant curvilinear relationship between grief and PTG in shidu parents. High levels of grief coupled with high levels of interpersonal loss may interfere with their ability to achieve PTG. Therefore, evaluating degrees of interpersonal loss seems to be an important part of the treatment process when working with shidu parents. To facilitate their adaptation from a positive perspective, helping them maintain existing or develop new interpersonal relationships may be helpful.

Dynamics of Chinese Shidu Parents’ Vulnerability in Old Age –A Qualitative Study

Shidu is a Chinese word, referring to a group of bereaved parents who were subject to the One-Child Policy and whose only child has died. Living in a society where care for older people largely relies on adult children, Shidu parents can be highly vulnerable due to losing an only child who may be their primary resource for old age security. Despite the noticeable rise of Shidu families in China, these vulnerable parents have often been overlooked in society and neglected by government policies. This article adopts a qualitative approach to analyse interviews with 15 older Shidu parents and four support professionals, capturing dynamic experiences of these parents’ vulnerability in grief, elderly care and end-of-life care. Through a sociological lens, these Shidu parents are found to have adapted, revised and even rejected the status quo to cope with significant gaps in support and to negotiate for more meaningful support for their old age. This dynamic but distressing picture has also revealed a lack of ongoing structures that can effectively address these older Shidu parents’ multifaceted and changing needs. Based on the findings, recommendations are made aiming to inform future practice and policymaking for older Shidu parents.

A profile analysis of post-traumatic stress disorder and depressive symptoms among Chinese Shidu parents

BACKGROUND

Due to the one-child policy implemented in China, most families have only one child. When parents experience the death of their only child, these parents receive the label 'Shidu parents'. Shidu is a major public health issue in China. However, the patterns of post-traumatic stress disorder (PTSD) and depressive symptoms that are present in this population remain unclear.

OBJECTIVE

This study aims to identify profiles of PTSD and depressive symptoms among Shidu parents and to explore the predictors of profile membership.

METHODS

A total of 363 participants (M age = 61.5 years, SD = 7.5) were asked to complete questionnaires assessing PTSD, depressive symptoms, perceived social support, and demographic information. Latent profile analyses and multivariate logistic regressions were used.

RESULTS

Three distinct profiles were identified: low (39.4%), moderate (32.8%), and high symptoms (27.8%). Parents who were younger and perceived lower levels of support from family and significant others were more likely to experience higher levels of PTSD and depressive symptoms.

CONCLUSIONS

These results indicate that the severity of PTSD and depressive symptoms tightly cohere, providing evidence for the co-occurrence of PTSD and depressive symptoms after bereavement. The findings provide valuable information for the development of tailored professional interventions for bereaved parents.

Social support modulates the association between PTSD diagnosis and medial frontal volume in Chinese adults who lost their only child

Losing an only child is a devastating life event that a parent can experience and may lead to post-traumatic stress disorder (PTSD). Social support could buffer against the negative influence of this trauma, but the neural mechanism underlying this alleviation effect remains poorly understood. In this study, voxel-based morphometry was conducted on brain MRI of 220 Han Chinese adults who had lost their only child. We performed multiple regression analysis to investigate the associations between social support scores – along with PTSD diagnosis, age, sex, body mass index (BMI) – and brain grey matter (GM) volumes in these bereaved parents. For all trauma-exposed adults, social support-by-diagnosis interaction was significantly associated with medial prefrontal volume (multiple comparisons corrected P ˂ 0.05), where positive correlation was found in adults with PTSD but not in those without PTSD. Besides, PTSD diagnosis was associated with decreased GM volume in medial and middle frontal gyri (P ˂ 0.001, uncorrected); older age was associated with widespread GM volume deficits; male sex was associated with lower GM volume in rolandic operculum, insular, postcentral gyrus (corrected P ˂ 0.05), and lower GM in thalamus but greater GM in parahippocampus (P ˂ 0.001, uncorrected); higher BMI was associated with GM deficits in occipital gyrus (corrected P ˂ 0.05) and precuneus (P ˂ 0.001, uncorrected). In conclusions, social support modulates the association between PTSD diagnosis and medial frontal volume, which may play an important role in the emotional disturbance in PTSD development in adults who lost their only child.

Effects of COMT rs4680 and BDNF rs6265 polymorphisms on brain degree centrality in Han Chinese adults who lost their only child

Losing one's only child is a major traumatic life event that may lead to posttraumatic stress disorder (PTSD); however, not all parents who experience this trauma develop PTSD. Genetic variants are associated with the risk of developing PTSD. Catechol-O-methyltransferase (COMT) rs4680 and brain-derived neurotrophic factor (BDNF) rs6265 are two most well-described single-nucleotide polymorphisms that relate to stress response; however, the neural mechanism underlying their effects on adults who lost an only child remains poorly understood. Two hundred and ten Han Chinese adults who had lost their only child (55 with PTSD and 155 without PTSD) were included in this imaging genetics study. Participants were divided into subgroups according to their COMT rs4680 and BDNF rs6265 genotypes. Degree Centrality (DC)-a resting-state fMRI index reflecting the brain network communication-was compared with a three-way (PTSD diagnosis, COMT, and BDNF polymorphisms) analysis of covariance. Diagnosis state had a significant effect on DC in bilateral inferior parietal lobules and right middle frontal gyrus (MFG), where PTSD adults showed weaker DC. BDNF × diagnosis interaction effect was found in the right MFG and hippocampus, and these two regions were reversely modulated. Also, there was a significant COMT × BDNF interaction effect in left cuneus, middle temporal gyrus, right inferior occipital gyrus, and bilateral putamen, independent of PTSD diagnosis. These findings suggest that the modulatory effect of BDNF polymorphism on the MFG and hippocampus may contribute to PTSD development in bereaved adults. Interactions of COMT × BDNF polymorphisms modulate some cortices and basal ganglia, irrespective of PTSD development.

The relationship between post-traumatic stress disorder and suicidal ideation among shidu parents: the role of stigma and social support

BACKGROUND

Losing an only child is a particularly traumatic and heartbreaking event for parents, which can trigger a lot of emotional responses, including PTSD and suicidal ideation (SI). The objectives of this study were mainly to identify predictors of SI and examine the interactions of PTSD with stigma and social support on SI among shidu parents.

METHODS

A total of 507 shidu parents from Shenyang, China were included in this cross-sectional study. Bivariate logistic regression analyses were conducted to explore risk or protective factors associated with SI. Interactions of PTSD with stigma and social support on SI were also examined by bivariate logistic regression analyses.

RESULTS

The prevalence of SI among shidu parents was 11.24%. PTSD (OR = 2.23, p < 0.05) and stigma (OR = 4.66, p < 0.01) were positively associated with SI. Social support was negatively associated with SI (OR = 0.90, p < 0.01). For individuals with PTSD, the presence of stigma was more likely to lead to SI. For individuals with PTSD, an increased level of social support was less likely to lead to SI.

CONCLUSIONS

SI is a serious issue among shidu parents. Stigma aggravated the effect of PTSD on SI, while social support buffered the effect of PTSD on SI among shidu parents.

Assessing the impact of the "one-child policy" in China: A synthetic control approach

There is great debate surrounding the demographic impact of China's population control policies, especially the one-birth restrictions, which ended only recently. We apply an objective, data-driven method to construct the total fertility rates and population size of a 'synthetic China', which is assumed to be not subjected to the two major population control policies implemented in the 1970s. We find that while the earlier, less restrictive 'later-longer-fewer' policy introduced in 1973 played a critical role in driving down the fertility rate, the role of the 'one-child policy' introduced in 1979 and its descendants was much less significant. According to our model, had China continued with the less restrictive policies that were implemented in 1973 and followed a standard development trajectory, the path of fertility transition and total population growth would have been statistically very similar to the pattern observed over the past three decades.

Life Restoration and Future Care Preparation Among Older Parents in Shanghai Who Have Lost Their Only Adult Child

The combination of aging and losing their only adult child challenges an increasing number of older adults in China. Current literature primarily focuses on older parents' bereavement but seldom examines their effort to cope with subsequent life changes brought about by only-child loss. This study explores how older parents in Shanghai who lost their only adult child restore their lives and prepare for future care. Twenty-four older adults were purposively sampled and participated in face-to-face, in-depth interviews. The findings suggest that participants tried to restore their lives by rationalizing grief and expanding their social networks. Despite their losses, participants remained in favor of family caregiving and reluctantly prepared for future care. Their ambivalent attitudes toward government support call for caution in approaches to service delivery.

The relationship between hope and post-traumatic stress disorder in Chinese shidu parents: The mediating role of perceived stress

BACKGROUND

Parents who lost their only child and can not conceive another child, are known as shidu parents in China. This study aimed to estimate the prevalence of post-traumatic stress disorder (PTSD) and examine the mediating role of perceived stress between hope and PTSD symptoms in Chinese shidu parents.

METHODS

295 shidu mothers and 197 shidu fathers were recruited in Shenyang city. Shidu parents were asked to complete a questionnaire including the PTSD Checklist for DSM-5 (PCL-5), the Herth hope index (HHI) and the Perceived Stress Scale-10 (PSS-10). Hierarchical linear regression was performed to assess the associations among hope, perceived stress and PTSD symptoms. Asymptotic and resampling strategies were used to explore the mediating role of perceived stress.

RESULTS

The prevalence of PTSD in Chinese shidu parents was 23.78%. Mothers were more likely to develop PTSD than fathers. For shidu fathers, the proportion of mediation of perceived stress was 39.48%. For shidu mothers, the proportion of mediation of perceived stress was 40.00%.

LIMITATIONS

Due to the cross-sectional design, the findings of the present study can not be used to establish formal causal relationships or to determine the direction of causality. Longitudinal studies are need to validate our findings.

CONCLUSIONS

Perceived stress partly mediated the relationship between hope and PTSD symptoms in Chinese shidu parents. The interventions of hope and perceived stress should be included in PTSD prevention. More assistance should be directed to improve the mental health of shidu mothers.

Maternity migration and the recent normalization of the sex ratio at birth in Hong Kong

Hong Kong is characterized by very low fertility. However, over a period from 2000 to 2015, both the total number of births and the sex ratio at birth (SRB) increased and then declined dramatically. We analysed the increases in a 2013 paper in this journal, where we largely ascribed them to a rapid growth in the number of 'transient' mothers from Mainland China disproportionately giving birth to boys in the territory. In 2012, policies were implemented to halt this 'maternity migration'. Here, we explore the impact of these policies, both on births and the SRB in Hong Kong. We conclude that the rises and falls in births and SRBs in Hong Kong can, indeed, be broadly ascribed to the reproductive behaviour of transient Mainland mothers. However, the role of the Hong Kong government's policy interventions is much less clearly defined.

End-of-Life Care Preference: Examination of Chinese Adults with Children and Those Who Lost Their Only Child

BACKGROUND

Little is known about the end-of-life (EOL) care preference and its associated factors among community-dwelling adults in Mainland China. This study investigated the EOL care preference and its associated factors among community-dwelling Chinese adults in Shanghai, China.

METHODS

A cross-sectional survey was conducted in Shanghai, China, from April to June in 2013. A total of 1200 older adults aged 60 years and older and another 200 middle-aged and older adults aged 45 years and older who lost their only child were included in the current study. In the current study, the EOL care preference included three categories: preferred family care, preferred care provided by visiting healthcare professionals, and preferred care in a specialized EOL care institute. Childlessness was coded as lost the only child, had children but not coresiding, and had coresiding children. Mor and Hiris's model of choices of setting at the EOL was used to explore the EOL care preference and its associated factors, including sociodemographic characteristics, support networks, functional characteristics, and healthcare system. Multinomial logistic regressions were used to estimate the factors associated with their EOL care preference.

RESULTS

In terms of EOL care preference, adults who lost their only child preferred care provided by a specialized EOL care institute (58.43%), while adults who had children preferred family care at home (46.72% for adults who did not coreside with children and 49.04% for those who did). Results from multinomial logistic regressions showed that adults with higher income, having properties, and having children tended to opt for family care at home. Participants with friends' support preferred EOL care provided by visiting healthcare professionals or specialized EOL care institutions over family care at home.

CONCLUSIONS

Income, wealth, having children, and having friends' support were significant factors that were associated with the EOL care preference among Chinese adults. Home-based EOL care, professional and individualized hospice, or palliative care provided by institutions need to be developed in China.

Can China afford rapid aging?

China’s rapid aging has caused widespread concern, but it seems that the situations and consequences of rapid aging are not adequately acknowledged. This study analyzed the problem of ageing in China from the aspects of elderly people’s health status, income source, daily care, suicide, the weak social security system in terms of pension, health expenses, and long-term care costs as well as incoming accelerating ageing process in China. All these factors indicate that it is difficult for China to afford the issue of a rapidly aging population.
