Somatic symptoms and insomnia among bereaved parents and siblings eight years after the Utøya terror attack

Background: Levels of prolonged grief symptoms (PGS) and post-traumatic stress symptoms (PTSS) can be high, many years following bereavement after terror, but knowledge concerning somatic health is scarce. Terrorism is a serious public health challenge, and increased knowledge about long-term somatic symptoms and insomnia is essential for establishing follow-up interventions after terrorism bereavement.Objective: To study the prevalence of somatic symptoms and insomnia and their association with PGS, PTSS, and functional impairment among terrorism-bereaved parents and siblings.Methods: A cross-sectional quantitative study included 122 bereaved individuals from the Utøya terror attack in Norway in 2011. The sample comprised 88 parents and 34 siblings aged 19 years and above (Mage = 49.7 years, SDage = 13.8 years, 59.8% females). The participants completed questionnaires 8 years after the attack assessing somatic symptoms (Children's Somatic Symptoms Inventory) and insomnia (Bergen Insomnia Scale) along with measures of PGS (Inventory of Complicated Grief), PTSS (Impact of Event Scale-Revised), and functional impairment (Work and Social Adjustment Scale).Results: Fatigue was the most frequently reported somatic symptom (88% of females and 65% of males). Females reported statistically significantly more somatic symptoms than males. In total, 68% of the bereaved individuals scored above the cut-off for insomnia. There were no statistically significant gender differences for insomnia. Female gender, intrusion, and arousal were associated with somatic symptoms. Intrusion and somatic symptoms were associated with insomnia. Somatic symptoms, avoidance, and hyperarousal were associated with functional impairment.Conclusion: Many bereaved parents and siblings report somatic symptoms and insomnia eight years after the terror attack. Somatic symptoms are associated with functional impairment. Long-term follow-up and support after traumatic bereavement should focus on somatic symptoms and insomnia.

The associations of grief-related rumination with prolonged grief and posttraumatic stress symptoms: A longitudinal study of bereaved after the 2011 terror attack in Norway

After the sudden and violent death of a loved one, many bereaved experience symptoms of prolonged grief (PG) and posttraumatic stress (PTS). The present study investigated the cross-sectional and longitudinal associations of grief-related rumination with PG and PTS symptoms among bereaved parents and siblings after the Utøya terror attack in Norway on 22 July 2011 (N = 110, Mage  = 43.2 years, 59.1% female). Participants' responses on the Rumination Scale, the Inventory of Complicated Grief and the Impact of Event Scale-Revised 28, 40 and 102 months after the loss were analysed. Cross-sectionally and longitudinally, grief-related rumination was positively and strongly linked with PG and PTS symptoms. When controlling for the baseline levels of PG and PTS symptoms and demographics of the sample, grief-related rumination predicted PG symptoms after 12 months but not after 74 months. Further, grief-related rumination predicted significantly the PTS symptoms of avoidance after 12 and 74 months and hyperarousal after 74 months beyond sample demographics and baseline symptoms. The results suggest that grief-related rumination is an important factor in PG and PTS symptoms after traumatic bereavement.

Grief trajectories among bereaved parents after the 2011 Utøya terror attack: A qualitative analysis

This study took a qualitative approach to explore terror-bereaved parents' long-term experiences with grief. Data were drawn from a larger, longitudinal study, and interviews with 10 bereaved parents were selected based on their reported change in scores on Inventory of Complicated Grief (ICG) over a period of 6.5 years, including the five parents with the largest change (group 1) and the five parents with the least change (group 2). Reflexive thematic analysis of the interview transcripts resulted in four main themes: "I felt completely lost and helpless, like I was stuck in a whirlwind" and "I have been fighting to get back to my everyday life", which both groups contributed to. Participants in group 1 contributed to the theme "I have found a way to a new life," while participants in group 2 contributed to the theme "I cannot seem to find a way to a new life." Findings suggest that sense of control, acceptance, and social support enhanced experienced coping following terror-related bereavement, while comorbid mental health problems, difficulties with acceptance, and repetitive thoughts about the death was experienced as contributing to long-term struggles following terror-related bereavement.

Paths to positive growth in parents bereaved by drug-related death: A mixed-method study

Introduction

Drug-related deaths (DRDs) are a major public health challenge. Losing a child to a DRD can be a very stressful life event, which places parents at risk of mental and physical health problems. However, traumatic experiences like losing a child to DRD can paradoxically also lead to positive psychological changes. A mixed-method approach was used to understand the complexity of the phenomenon of post-traumatic growth experienced by parents following a DRD.

Method

By combining data from a survey (n = 89) and interviews (n = 14), we explored positive growth experiences among Norwegian parents. We conducted descriptive analyses of the sample’s demographic characteristics and mean scores for Post-traumatic Growth Inventory (PTGI-SF) items. Hierarchical multiple regression was used to examine the influence of the ability to perform daily activities (WSAS), self-efficacy (GSE-SF), social support (CSS), and symptoms of prolonged grief (PG-13) on the outcome variable of post-traumatic growth (PTGI-SF). Reflexive thematic analysis was applied to analyze the qualitative data. Finally, we integrated the results of the survey and the interviews.

Results

For items measuring post-traumatic growth, parents scored highest on the item “I discovered that I’m stronger than I thought I was” and lowest on the item “I am able to do better things with my life.” Self-efficacy and social support had a statistically significant relation with post-traumatic growth. Two themes were generated from the interviews: (I) new perspectives on life and (II) new paths in life. Even though the “New Possibilities” subscale had the lowest mean score for the PTGI-SF, new paths in life were important for many of the interviewed parents.

Discussion

Parents described traumatic stressors associated with having a child who uses narcotics and hence experienced positive changes even before losing their child. We argue that on an individual level, the consequences of spillover stigma, low self-efficacy, and intrusive rumination can hinder potential post-traumatic growth. On a group level, enhancing network support may increase post-traumatic growth experiences. Hence, parents who have experienced a DRD can benefit from help to activate their social networks and strengthen their self-efficacy.

Delayed post-traumatic stress and memory inflation of life-threatening events following a natural disaster: prospective study

BACKGROUND

The causes of delayed post-traumatic stress disorder (PTSD) are debated, and the validity of late-onset PTSD has been questioned.

AIMS

We aimed to examine predictors of delayed PTSD in a community sample of survivors of a natural disaster.

METHOD

Norwegian survivors of the 2004 Indian Ocean tsunami (n = 532) responded to a questionnaire at 6 and 24 months post-disaster. The questionnaire measured PTSD symptoms, recalled exposure and immediate stress responses to the disaster, recalled perceived life threat, personality dimensions, social support and other subsequent adverse life events.

RESULTS

When dichotomising PTSD symptom scores, 331 participants had low and 194 had high PTSD scores (early-onset PTSD) at 6 months. Of those with initially low scores, 43 (13.0%) had high symptom scores (delayed PTSD) at 24 months. The delayed PTSD group had a lower degree of initially assessed threat and witness experiences of death or suffering, lower immediate stress response and higher degree of memory inflation of perceived threat than the early-onset PTSD group. Among those with low PTSD scores at 6 months, onset of delayed PTSD was associated with neuroticism and memory inflation of life threat, but not with the degree of initially assessed disaster exposure or reports of subsequent adverse life events.

CONCLUSIONS

Lack of association between trauma exposure and delayed onset of PTSD symptoms casts doubt on whether the traumatic event is actually the primary causative factor for delayed PTSD. Our findings suggest that delayed PTSD may be a manifestation of personality factors and memory inflation of the severity of an event.

Different Trajectories of Prolonged Grief in Bereaved Family Members After Terror

Introduction: The loss of a loved one in a terror incident is associated with elevated risk for mental health disorders such as prolonged grief disorder (PGD) and posttraumatic stress disorder (PTSD), but the long- term adaptation after such losses are not well understood. This study aims to explore the trajectories of PGD among parents and siblings (n = 129) after the 2011 terror attack on Utøya Island, Norway. Methods: The 19-item Inventory of Complicated grief (ICG) was used to measure PGD at 18, 28, and 40 months post-loss. Latent class growth analysis (LCGA) was used to identify trajectories of grief and a multinomial regression analysis was conducted to examine predictors of class membership. Results: The analysis identified three grief trajectories; moderate/decreasing class (23%), high/slow decreasing class (64%), and a high/chronic class (13%). Predictors of high/slow recovery or chronic grief was female gender, previous depressive symptoms, and intrusion and avoidance symptoms. Conclusion: The findings highlights the difficult grief process and slow recovery that characterizes the majority of close family members bereaved by a terror-incident. Community mental health programs should strive for both early outreach and long-term follow-up after such incidents.

Octave-wide supercontinuum generation of light-carrying orbital angular momentum

Nonlinear frequency generation of light-carrying orbital angular momentum (OAM), which facilitates realization of on-demand, frequency-diverse optical vortices, would have utility in fields such as super-resolution microscopy, space-division multiplexing and quantum hyper-entanglement. In bulk media, OAM beams primarily differ in spatial phase, so the nonlinear overlap integral for self-phase matched χ⁽³⁾ processes remains the same across the 4-fold degenerate subspace of beams (formed by different combinations of spin and orbital angular momentum) carrying the same OAM magnitude. This indistinguishable nature of nonlinear coupling implies that supercontinuum generation, which substantially relies on self/cross-phase modulation, and Raman soliton shifting of ultrashort pulses typically results in multimode outputs that do not conserve OAM. Here, using specially designed optical fibers that support OAM modes whose group velocity can be tailored, we demonstrate Raman solitons in OAM modes as well as the first supercontinuum spanning more than an octave (630 nm to 1430 nm), with the entire spectrum in the same polarization as well as OAM state. This is fundamentally possible because spin-orbit interactions in suitably designed fibers lead to large effective index and group velocity splitting of modes, and this helps tailoring nonlinear mode selectivity such that all nonlinearly generated frequencies reside in modes with high spatial mode purity.

Early intervention for bereaved children: What mental health professionals think

People rarely specify what "early intervention" following bereavement means, so we explored the views of experienced professionals working primarily with bereaved children. In an anonymous online survey, 84 mental health professionals answered questions about the content and timeframe of early intervention. The types of interventions varied, but conversation and support were most frequent. Most considered early intervention to mean before or during the first month following the loss. Although meta-analyses show little benefit of early intervention, professionals disagree and see the need to tailor interventions to the type of death, the situation of the family, and the intensity of reactions.

A Relational Perspective on Social Support Between Bereaved and Their Networks After Terror: A Qualitative Study

The aim of this study is to increase the understanding of social network support after traumatic deaths and, by demonstrating the complexities of such encounters, to highlight whether such support may be totally beneficial. A phenomenological dynamic and relational perspective was applied to 22 in-depth interviews with parents bereaved as a result of the 2011 terror attack in Norway. Three main themes were identified in respect of interactional support processes: (a) valued support, (b) stressful experiences, and (c) interactive barriers. As well as describing the value of experienced support, the article also elaborates on the effect of lacking, avoidant, and inept support. The findings show that insecure communication and a nonmatching understanding of time and emotional overload can form interactive barriers between the bereaved and their networks. By better understanding the relational regulation processes inherent in social support we may provide informed advice to both the bereaved and their networks to maximize recovery.

Monoclonal Antibodies to Human 54,000 Molecular Weight Plasminogen Activator Inhibitor from Fibrosarcoma Cells - Inhibitor Neutralization and One-Step Affinity Purification

Mouse monoclonal antibodies were derived against a plasminogen activator inhibitor with a mol.wt. of ∼54,000 (54 K) from the human fibrosarcoma cell line HT-1080. Screening for hybrids producing antibodies directed against the inhibitor was performed with enzyme-linked immunosorbent assay and SDS-polyacrylamide gel electrophoresis (SDS-PAGE) followed by immunoblotting. Four clones of hybridomas producing IgG1 antibodies were further characterized. The inhibitor was purified ∼50-fold to homogeneity from conditioned cell culture fluid with a yield of ∼85% by a one-step procedure using Sepharose-conjugated monoclonal antibody. In the 125I-fibrin plate assay one of the antibodies neutralized the effect of the inhibitor on urokinase-type plasminogen activator. Two of the antibodies bound complexes between urokinase-type plasminogen activator and inhibitor while the remaining two antibodies did not. The antibodies could be used for immunocytochemical localization of the inhibitor in HT-1080 cells. All four antibodies cross-reacted with a plasminogen activator inhibitor derived from cultured human umbilical cord endothelial cells.

Can visiting the site of death be beneficial for bereaved families after terror? A qualitative study of parents' and siblings' experiences of visiting Utøya Island after the 2011 Norway terror attack

Background. After the 2011 terror attack on Utøya Island, a collective visit was organized for bereaved families. There is limited knowledge whether bereaved families can benefit from such visits after terror. Objective. This study aims to explore how bereaved families experienced visiting the site of death after the 2011 terror attack. Method. As part of in-depth interviews, 22 parents and 16 siblings were asked whether they had visited Utøya and, if so, how they experienced the visit. Participants' responses were analysed using thematic analysis. Results. The results showed that for the majority of the bereaved, visiting Utøya had been important in processing their loss. Three key themes emerged as to what they considered important with the visit: 'seeing the actual place of death', 'seeking factual information', and 'learning to know the island'. These factors were associated both with beneficial reactions (e.g. accepting the reality of the loss increased cognitive clarity) and with distressing reactions (e.g. intrusive thoughts, re-enactment images), but the benefits had outweighed the distress. Having the opportunity for multiple visits seemed to optimize the benefits. Conclusion. Bereaved families should be offered the opportunity to visit the site of death after terror.

Early Interventions Following the Death of a Parent: Protocol of a Mixed Methods Systematic Review

BACKGROUND

Previous meta-analyses examined the effectiveness of interventions for bereaved children showing small to moderate effect sizes. However, no mixed methods systematic review was conducted on bereavement interventions following the loss of a parent focusing on the time since death in regard to the prevention of grief complications.

OBJECTIVE

The overall purpose of the review is to provide a rigorous synthesis of early intervention after parental death in childhood. Specifically, the aims are twofold: (1) to determine the rationales, contents, timeframes, and outcomes of early bereavement care interventions for children and/or their parents and (2) to assess the quality of current early intervention studies.

METHODS

Quantitative, qualitative, and mixed methods intervention studies that start intervention with parentally bereaved children (and/or their parents) up to 6 months postloss will be included in the review. The search strategy was based on the Population, Interventions, Comparator, Outcomes, and Study Designs (PICOS) approach, and it was devised together with a university librarian. The literature searches will be carried out in the Medical Literature Analysis and Retrieval System Online (MEDLINE), PsycINFO, Excerpta Medica Database (EMBASE), and Cumulative Index to Nursing and Allied Health Literature (CINAHL). The Mixed Methods Appraisal Tool will be used to appraise the quality of eligible studies. All data will be narratively synthetized following the Guidance on the Conduct of Narrative Synthesis in Systematic Reviews.

RESULTS

The systematic review is ongoing and the data search has started. The review is expected to be completed by the end of 2017. Findings will be submitted to leading journals for publication.

CONCLUSIONS

In accordance with the current diagnostic criteria for prolonged grief as well as the users' perspectives literature, this systematic review outlines a possible sensitive period for early intervention following the death of a parent. The hereby presented protocol ensures the groundwork and transparency for the process of conducting the systematic review.

Shift work, mental distress and job satisfaction among Palestinian nurses

BACKGROUND

Associations between shift work (SW) schedules, mental distress and job satisfaction have never been completely described.

AIMS

To examine gender-specific associations of SW with mental distress and job satisfaction in nurses in Hebron District, Palestine, in 2012.

METHODS

Detailed information on work schedules (day versus shift), socio-demographic status, mental distress (General Health Questionnaire, GHQ-30) and job satisfaction (Generic Job Satisfaction Scale) in nurses employed in Hebron District, Palestine, was obtained through a questionnaire survey. Associations of SW and outcomes were examined by linear regression analysis.

RESULTS

Of 372 nurses eligible for the study, 309 and 338 completed surveys regarding mental distress and job satisfaction, respectively. The sample comprised 62% women and 38% men. After adjusting for covariates, women working shifts reported significantly higher levels of mean mental distress [β coefficient 3.6; 95% confidence interval (CI) 0.3-7.0] compared with women working regular day shifts. Men working shifts reported significantly lower levels of job satisfaction (-3.3; 95% CI -6.2 to -0.5) than men working regular day shifts. Women reported higher levels of mental distress than men, but this was unrelated to work schedule.

CONCLUSIONS

In this study, nurses working shifts reported higher levels of mental distress and lower levels of job satisfaction, although these associations were weaker when adjusted for potential covariates. There was no evidence of a gender differential in the association between SW and mental distress and job satisfaction.

In What Ways Do Bereaved Parents After Terror Go on With Their Lives, and What Seems to Inhibit or Promote Adaptation During Their Grieving Process? A Qualitative Study

The aim of this article was to identify the ways in which bereaved parents go on with their lives following terror killings and to discuss what appears to inhibit or promote adaptation during their grieving process. The results of the study are aimed at presenting advice to professional helpers. From 22 in-depth interviews with parents bereaved by the 2011 terror attack in Norway, four main themes concerning coping were identified: (a) decisions, mindsets, and cognitions; (b) proactive and confronting activities; (c) avoidant and protective activities; (d) coping through support and assistance. A variety of coping strategies were employed: avoidance, protection and distraction, adaptive and maladaptive rumination, thought control, and confrontation. Most parents used several strategies to varying degrees and interchangeably over time, likely more or less adaptive and functional. The importance of helping the bereaved flexibly regulate the oscillation between loss-oriented and restoration-orientated life-tasks is emphasized for helping them cope effectively.

Grief and Traumatic Grief in Children in the Context of Mass Trauma

Children who have had someone close die as a result of a mass trauma event such as war, armed conflict, acts of terror, political violence, torture, mass accidents, and natural disasters are at risk for biopsychosocial problems. Research on how to classify when grief becomes complicated or traumatic in children is scarce, and while functioning level may provide a good indication, assessing functioning may be difficult in mass trauma environments where routines and structure are often lacking. There are promising trauma- and grief-focused interventions for children post-mass trauma, which are mostly provided in school settings. However, more advanced multi-method interventions are needed that address grief and trauma in the context of the child's overall mental health, parent/caregiver role in assisting the child, family system issues, ways to provide safe caring environments amidst chaos and change, and interventions that take into account local consumer perspectives, including the voices of children.

On the scalability of ring fiber designs for OAM multiplexing

The promise of the infinite-dimensionality of orbital angular momentum (OAM) and its application to free-space and fiber communications has attracted immense attention in recent years. In order to facilitate OAM-guidance, novel fibers have been proposed and developed, including a class of so-called ring-fibers. In these fibers, the wave-guiding region is a high-index annulus instead of a conventional circular core, which for reasons related to polarization-dependent differential phase shifts for light at waveguide boundaries, leads to enhanced stability for OAM modes. We review the theory and implementation of this nascent class of waveguides, and discuss the opportunities and limitations they present for OAM scalability.

Prevalence of psychiatric disorders and functional impairment after loss of a family member: a longitudinal study after the 2004 Tsunami

BACKGROUND

Bereavement following disasters is a devastating experience for family members. The aim of this study was to examine the long-term mental health effects of losing a loved one in a natural disaster.

METHODS

Ninety-four Norwegians aged 18-80 years who lost close family members in the 2004 Southeast Asian tsunami were evaluated 2 and 6 years after the disaster. The participants were either staying in an affected area at the time of the disaster (i.e., directly exposed) or not (i.e., not directly exposed). The prevalence of psychiatric disorders was assessed by the MINI International Neuropsychiatric Interview (M.I.N.I). Prolonged grief disorder (PGD) was self-reported using the Inventory of Complicated Grief (ICG), and functional impairment was self-reported using the Work and Social Adjustment Scale (WSAS).

RESULTS

We did not identify a significant decrease in the prevalence of PGD, posttraumatic stress disorder (PTSD), or major depressive disorder (MDD) from 2 to 6 years. Approximately, one-third of the bereaved (36%) had a psychiatric disorder 6 years after the tsunami. The most common disorder was PGD (12%) followed by general anxiety disorder (GAD, 11%), agoraphobia (11%), and MDD (10%). The prevalence of PTSD and MDD was higher among family members who were directly exposed to the disaster compared to those who were not (21 vs. 0%, and 25 vs. 3%). PGD was associated with functional impairment independent of other disorders.

CONCLUSIONS

Loss of a close family member in a natural disaster can have a substantial adverse long-term effect on mental health and everyday functioning.

Respiratory function and chemical exposures among female hairdressers in Palestine

BACKGROUND

Hairdressers are exposed to chemicals and work tasks that may cause respiratory symptoms. There is little awareness of occupational health among hairdressing salons in Palestine.

AIMS

To characterize respiratory symptoms, lung function, and knowledge of exposure to hazards among female Palestinian hairdressers.

METHODS

Cross-sectional study of female hairdressers and controls of female university students and staff. Working history and respiratory symptoms were collected using questionnaire. Lung function was measured. Working conditions were characterized in salons.

RESULTS

A total of 170 hairdressers from 56 salons and 170 controls participated. Nineteen per cent of the hairdressers reported wheezing versus 11% in the control group. The mean forced vital capacity was 3.31 l compared with 3.42 l for controls. Adjusting for age and height, there was a forced expiratory volume in 1 s reduction of 0.093 l (95% confidence interval (CI) = 0.06-0.15) comparing hairdressers with controls. A small number of hairdressers used respiratory protective equipment, and satisfactory ventilation in salons were lacking.

CONCLUSIONS

Female hairdressers had higher prevalence of reported asthma and respiratory symptoms than the controls, but these differences reduced markedly when adjusted for age, height, weight and years of education. They had lower lung function measurements than the control group. Increasing the awareness of occupational health hazards and improving the work conditions for the hairdressers in Palestine is needed. Possible bias could be present as hairdressers might have over reported symptoms or lung function measurements might be affected by differences in socioeconomic status between the two groups.

Visiting the site of death: experiences of the bereaved after the 2004 Southeast Asian Tsunami

The authors examined how many bereaved relatives of Norwegian tourists who perished in the 2004 Southeast Asian Tsunami had visited the site of death and the most important outcome from the visit. We conducted in-depth interviews (n = 110) and used self-report questionnaires (Impact of Event Scale-Revised, Inventory of Complicated Grief and General Health Questionnaire) in a total of 130 first-degree family members 2 years post-disaster. Results showed that the majority of participants (n = 113; 87%) had visited the site of death. The most important outcome was gaining an increased understanding of what occurred (61%) and a feeling of closeness to the deceased (27%). Those who had visited the site of death reported lower avoidance behavior and higher degree of acceptance of the loss than non-visitors. Although this could be a cause as well as a consequence of the visit, visiting the site of death may be an important part of the support offered to bereaved families after experiencing a disaster loss.

Bereavement and mental health after sudden and violent losses: a review

This paper reviews the literature on the psychological consequences of sudden and violent losses, including disaster and military losses. It also reviews risk and resilience factors for grief and mental health and describes the effects and possible benefit of psychosocial interventions. The review shows gaps in the literature on grief and bereavement after sudden and violent deaths. Still, some preliminary conclusions can be made. Several studies show that a sudden and violent loss of a loved one can adversely affect mental health and grief in a substantial number of the bereaved. The prevalence of mental disorders such as post-traumatic stress disorder (PTSD), major depressive disorder (MDD), and prolonged grief disorder (PGD, also termed complicated grief) varies widely, however, from study to study. Also, mental health disorders are more elevated after sudden and violent losses than losses following natural deaths, and the trajectory of recovery seems to be slower. Several factors related to the circumstances of the loss may put the bereaved at heightened risk for mental distress. These factors may be differentially related to different outcomes; some increase the risk for PTSD, others for PGD. Given the special circumstances, bereavement following sudden and violent death may require different interventions than for loss from natural death. Recommendations for future research and clinical implications are discussed.

Lung function and respiratory symptoms in male Palestinian farmers

In a cross-sectional study of 250 farmers aged 22 to 77 years, of whom 36.4% are smokers, the authors aimed at describing lung function and respiratory symptoms and to estimate associations with exposures to pesticides and dust. Lung function was measured using a spirometer. Respiratory symptoms and exposure levels were self-reported based on a modified standardized questionnaire. Mean forced vital capacity (FVC) was 4.20 L (SD = 0.93 L), 95.51% of predicted as compared to European standards. Mean forced expiratory volume in one second (FEV(1)) was 3.28 L (SD = 0.80 L), 91.05% of predicted. The authors found high symptom prevalences: 14.0% for chronic cough; 26.4% for wheeze; and 55.2% for breathlessness. There was no clear association between exposure to pesticides or dust and lung function or between such exposures and respiratory symptoms. However, a significant association was found between smoking and respiratory symptoms such as chronic cough, cough with phlegm, and wheezes. The lack of farm exposure associations could be due to improvement in farmers' awareness to pesticides hazards as well as regulations of pesticide import, or because of inherent problems with the experimental design. Farmers who kept animals and poultry seem to have less respiratory symptoms and better lung function.

Psychiatric disorders among disaster bereaved: an interview study of individuals directly or not directly exposed to the 2004 tsunami

BACKGROUND

Few studies have explored the long-term mental health consequences of disaster losses in bereaved, either exposed to the disaster themselves or not. This study examined the prevalence and predictors of mental disorders and psychological distress in bereaved individuals either directly or not directly exposed to the 2004 tsunami disaster.

METHOD

A cross-sectional study of 111 bereaved Norwegians (32 directly and 79 not directly exposed) was conducted 2 years postdisaster. We used a face-to-face structured clinical interview to diagnose current posttraumatic stress disorder (PTSD) and depression (major depressive disorder, MDD) and a self-report scale to measure prolonged grief disorder (PGD).

RESULTS

The prevalence of psychiatric disorders was twice as high among individuals directly exposed to the disaster compared to individuals who were not directly exposed (46.9 vs. 22.8 per 100). The prevalence of disorders among the directly exposed was PTSD (34.4%), MDD (25%), and PGD (23.3%), whereas the prevalence among the not directly exposed was PGD (14.3%), MDD (10.1%), and PTSD (5.2%). The co-occurrence of disorders was higher among the directly exposed (21.9 vs. 5.2%). Low education and loss of a child predicted PGD, whereas direct exposure to the disaster predicted PTSD. All three disorders were independently associated with functional impairment.

CONCLUSIONS

The dual burden of direct trauma and loss can inflict a complex set of long-term reactions and mental health problems in bereaved individuals. The relationship between PGD and impaired functioning actualizes the incorporation of PGD in future diagnostic manuals of psychiatric disorders.

Predictors of complicated grief after a natural disaster: a population study two years after the 2004 South-East Asian tsunami

The authors examined predictors of complicated grief (CG) in Norwegians 2 years after bereavement in the 2004 South-East Asian tsunami. A cross-sectional postal survey retrospectively covering disaster experiences and assessing CG according to the Inventory of Complicated Grief yielded 130 respondents (35 directly disaster-exposed and 95 not directly exposed), with 47.7% screening CG positive. They identified positive associations between CG and being female, losing a child or spouse, and time to death confirmation, and negative associations with previous losses, being employed, and receiving social support. Direct exposure did not increase CG risk. Support service providers should be aware of this high prevalence of severe, persistent grief.

Suicide in young Norwegians in a life course perspective: population-based cohort study

BACKGROUND

Suicide is a leading cause of death in young adults. Several risk factors are well known, especially those related to adult mental health. However, some risk factors may have their origin in the very beginning of life. This study examines suicide in the general Norwegian population in a life course perspective, with a main focus on early life factors.

METHODS

In this study, several national registers were linked, supplying personal data on biological and social variables from childhood to young adult age. Participants were all Norwegians live born during the period 1967-1976, followed up through 2004. Persons who died or emigrated before the year of their 19th birthday, at which age follow-up started, were excluded. Thus, the study population comprised 610 359 persons, and the study outcome was completed suicide.

RESULTS

1406 suicides (0.23%) were recorded, the risk being four times higher in men than in women. Suicide risk factors included not being firstborn (adjusted HR in men and women (95% CIs): 1.19 (1.05 to 1.36) and 1.42 (1.08 to 1.88)), instability of maternal marital status during childhood, parental suicide (mainly in women), low body mass index (only investigated in men), low education and indications of severe mental illness.

CONCLUSIONS

Suicide in young adults may be rooted in early childhood, and the effect is likely to act through several mechanisms, some of which may be linked to the composition and stability of the parental home. A life course perspective may add to our understanding of suicide.
