Couple distress after sudden infant or perinatal death: a 30-month follow up.

OBJECTIVE: To examine, using a 30-month prospective study, patterns of anxiety, depression and alcohol use in couples following stillbirth, neonatal death or sudden infant death syndrome. METHODOLOGY: One hundred and thirty-eight bereaved and 156 non-bereaved couples completed standardized interviews at 2, 8, 15 and 30 months post-loss. RESULTS: At all interviews, bereaved couples were significantly more likely than non-bereaved couples to have at least one distressed partner. Rarely were both partners distressed in either group. For bereaved couples, 'mother only' distress declined from 21% to 10% during the study. 'Father only' distress ranged from 7% to 15%, peaking at 30 months. Bereaved mothers who were distressed at 2 months reported significantly lower marital satisfaction at 30 months. CONCLUSIONS: At the couple level, the experience of a baby's death is multifaceted. Gender differences are common and partners' needs may change over time. Early recognition of these differences may facilitate longer-term adjustment for both partners.

'My beloved chloroform'. Attitudes to childbearing in colonial Queensland: a case study.

In 1847 the anaesthetic and analgesic properties of chloroform were discovered. This technology generated a new era for midwifery: mothers could be relieved of pain in childbirth. The introduction of chloroform for childbirth saw increasing medical dominance in obstetrics, traditionally in the hands of the midwife. At the same time the use of chloroform sparked a medical and moral controversy which lasted for several decades. On the one hand women were destined by the 'curse of Eve' to experience pain during childbirth; on the other, medical humanitarians and practitioners believed that there were technical and moral reasons for alleviating pain in childbirth. In concentrating on the debate historians have largely ignored the reactions of mothers to the introduction of the technology. This paper explores changing attitudes to childbearing within the context of colonial Queensland society, 1860-90, by examining the correspondence of an upper-class mother. Her education and liberal outlook, and a certain ambivalence towards motherhood, all influenced her attitude to the use of chloroform and the process of childbirth.

The mental health impact of stillbirth, neonatal death or SIDS: prevalence and patterns of distress among mothers.

Although stressful events have long been implicated in the onset of psychological disorder, available data suggest that the majority of individuals appear to escape serious impairment even following highly traumatic events. Related to this is the question of chronicity and whether those who do become impaired develop mental health problems of an ongoing nature. This paper documents the psychological adjustment of 194 women following a highly stressful event-the death of an infant due to stillbirth, neonatal death or SIDS. Anxiety and depression were measured on four occasions-at 2, 8, 15 and 30 months post-loss--using the Delusions Symptoms States Inventory (DSSI/sAD). For comparative purposes, the mental health of 203 mothers of a surviving infant was similarly assessed. The results demonstrate that bereaved mothers, as a group, manifest significantly higher rates of psychological distress than mothers of living infants for at least 30 months after their loss. Their impairment may be either acute or chronic in form. The majority of bereaved mothers appear not be develop serious mental health problems in response to the loss or experience psychological impairment that is usually self-limiting. For a smaller group of women, the death of a baby may herald serious and ongoing distress. Bereaved mothers who were not distressed soon (2 months) after the loss were unlikely to become so later, but those who were still distressed at 8 months were likely to remain so subsequently.

Estimating nonparticipation bias in a longitudinal study of bereavement.

Nonparticipants in epidemiological studies may differ in important respects from participants but the magnitude of this potential bias is rarely quantified. This study estimates the effect of nonparticipation on estimates of mental health problems following stillbirth, neonatal death or sudden infant death syndrome. Of 805 families approached, 512 (64 per cent) were recruited, of whom 77 per cent of mothers and 71 per cent of fathers completed four study interviews. Younger, unmarried, unemployed parents without private health insurance were less often recruited, and even if recruited, were less likely to complete the interview. By evaluating several possible scenarios, we estimated that had mothers lost to follow-up remained in the study, anxiety rates would have varied by no more than +/-4 per cent. Relative risks associated with bereaved-control comparisons would have differed little from the observed estimate of 2.33. Estimating the effects of initial nonresponse is more difficult but the adoption of a worst-case scenario produced a relative risk of 3.47. Despite systematic nonparticipation suggestive of social disadvantage, attrition-related bias may have had only a modest effect on anxiety and depression rate estimates. However, this may not be the case when sample loss is high, when associations between attrition and outcome are strong, and when attrition-related behaviour differs across comparison groups.

Gender differences in parental psychological distress following perinatal death or sudden infant death syndrome.

BACKGROUND: Stress responses of bereaved parents (mothers 194, fathers 143) who experienced infant loss were compared with parents (mothers 203, fathers 157) with a live born child. METHOD: Psychological distress using scales of anxiety, depression and alcohol use was compared at 2, 8, 15 and 30 months post-loss. RESULTS: Bereaved mothers showed significantly more anxiety/depression than controls at all four interviews. For bereaved fathers, anxiety/depression differed significantly from controls only at two months. Heavy alcohol use was significantly more prevalent at 2 and 30 months. Relative risks showed significant gender differences between bereaved parents at all four interviews for anxiety/depression. When this outcome was extended to include heavy drinking in addition to anxiety/depression, these differences diminished and were significant only at 2 and 8 months. CONCLUSION. Female responses are longer lasting and reflected by elevated levels of anxiety/depression. Male responses equally involve anxiety, depression and heavy alcohol consumption.

Psychological changes in parents eight months after the loss of an infant from stillbirth, neonatal death, or sudden infant death syndrome--a longitudinal study.

OBJECTIVE: We proposed to measure part of the natural history of grief by determining the changes in the psychological symptoms experienced by bereaved parents over the 8 months after the loss of an infant from sudden infant death syndrome (SIDS), neonatal death (NND), or stillbirth (SB). Parents were interviewed twice, at 2 and 8 months after the loss. METHODOLOGY: A total of 220 bereaved families (45 SIDS, 93 NND, and 82 SB) were compared with 226 control families who had a live born child. Comparison was based on responses to a standardized measure of anxiety and depression (Delusions-Symptoms-States Inventory). RESULTS: For separate cross-sectional comparison at both 2 and 8 months, significant differences were noted in the frequency of maternal symptoms of anxiety and depression between bereaved and control groups (P < .001). Such differences were present for paternal anxiety and depression at 2 months, but not 8 months. A second series of analysis examined longitudinal changes in symptom frequency between 2 and 8 months for each bereaved group. For mothers, the changes were significant for anxiety and depression: SIDS and NND (P < .001), SB (P < .01). For fathers, the changes for anxiety and depression in SIDS were P < .01; NND, P < .05 for anxiety and P < .01 per depression; changes were not significant for SB. At 2 months, relative risks for symptoms of maternal anxiety were significant for all three bereaved groups: SIDS, 22.4; NND, 5.4; and SB, 5.1. Comparable significant figures at 8 months were: SIDS, 5.5; NND, 3.9; and SB, 3.0, respectively. For depression the results for 2 months were: SIDS, 8.6; NND, 5.9; and SB, 6.7 (all significant) while at 8 months the results were: SIDS, 5.1; NND, 3.8; and SB, 2.4 (SB group not significant). For fathers the relevant risks were generally lower. At 2 months, anxiety levels were higher than controls in all three groups, and for depression in the SIDS and SB groups. At 8 months, significant results persisted only in the SB group. CONCLUSION: These data indicate that bereaved parents have a marked reduction in the symptoms of mental illness over the first 8 months after the loss. Although the changes over time are significant for both mothers and fathers, mothers at 8 months still demonstrated higher levels of anxiety and depression when compared with controls. These levels of symptoms are far less evident for fathers at 8 months.

Alcohol and drug usage in parents soon after stillbirth, neonatal death or SIDS.

The behaviour of bereaved parents with respect to their drug and alcohol ingestion was examined 2 months following the loss of an infant from stillbirth (SB) neonatal death (NND) or sudden infant death syndrome (SIDS). Responses from bereaved families (99 SB, 109 NND, 52 SIDS) were compared with 252 control families (who had a liveborn infant). There was no difference in self-medication using aspirin as the example. The use of sedative drugs was significantly higher in all bereaved mothers (but especially the SIDS group). Use of sedatives by fathers was significantly higher only in the SIDS group. There was also a greater frequency of heavy drinking of mothers in all the bereaved groups and fathers in the SIDS group. These results have implications for the understanding and care of families following infant loss.

The rise and fall of phrenology in Australia.

In the first half of the nineteenth century phrenology, which was claimed to be the first science of the mind, experienced enormous popularity in the western world. It gave rise to a widespread movement attracting the attention of the professional and lay members of society. In Australia, as elsewhere, it had influence in penology and criminology, psychiatry, notions of racial inferiority, education, anthropology and popular application. By the second half of the nineteenth century, following advances in the knowledge of neuro-anatomy, it became relegated to the status of a pseudo-science. As such, it remained popular with charlatans and the public well into the twentieth century.

Evolution of bereavement counselling in sudden infant death syndrome, neonatal death and stillbirth.

There have been changing attitudes to death and grief in Western society in recent centuries. During the twentieth century complex medical and social changes have resulted in changing attitudes to and experiences with death. Specifically, the impact of death in childhood is reviewed. In recent decades sudden and unexpected death associated with stillbirth, the newborn and infants appears to have a more profound affect on the bereaved parents than in the past when the overall death rates in childhood were higher. The evolution of parent support groups developed since the 1960s to alleviate the psychological trauma of unexpected and sudden death in childhood has been traced. These groups were founded initially for support with sudden infant death syndrome and later extended to include families with stillbirth and neonatal death.

Early parental responses to sudden infant death, stillbirth or neonatal death.

OBJECTIVE: To examine the mental health of parents after stillbirth (SB), neonatal death (NND) or sudden infant death syndrome (SIDS). DESIGN: The sampling frame from southeast Queensland was observed over 2.5 years. Control families were matched for birth date, sex of child, hospital and health insurance status. SETTING: Home interviews, by specially trained social workers, took place two months after the death of the infant. PARTICIPANTS: Results were based on 918 responses from 260 bereaved families (99 SB, 109 NND, 52 SIDS) and 252 control families, with a 63.6% overall participation rate. MAIN OUTCOME MEASURES: Questionnaires included standardised measures of anxiety, depression, biographic and demographic data. It was hypothesised that subject families would show more symptoms of anxiety and depression than control families, with mothers and parents affected by SIDS having the highest levels. RESULTS: Affected parents report significantly more psychological symptoms than controls, mothers more than fathers (P less than 0.001). Parents affected by SIDS showed more symptoms than other affected parents. High levels of anxiety were 14 times more likely in mothers affected by SIDS than controls (95% confidence interval, 5.4-36.6), with depression 12 times more likely (95% confidence interval, 3.8-43.5). Anxiety for groups affected by SB and NND were respectively 3.9 (2.1-10.5) and 6.5 (2.6-16.3) times more likely than for controls, and depression 6.9 (2.1-22.5) and 8.5 (2.7-26.7) times more likely. Differences were less marked for fathers, except for fathers affected by SIDS. CONCLUSIONS: Parents affected by stillbirth, neonatal death or sudden infant death syndrome manifest high levels of anxiety and depression two months after the death. Mothers have more symptoms than fathers, and parents affected by SIDS have the most symptoms of anxiety and depression.

Child abuse in nineteenth century Queensland.

Various forms of the social and medical dilemma now referred to as child abuse occurred in 19th century Queensland. Incidents ranging from parental carelessness and neglect to deliberate injury and murder were reported in the lay and medical press. This paper investigates abuse of infants in Queensland in the latter half of the 19th century in the context of socioeconomic conditions, family stress, concepts of morality and prevailing social mores. Identifiable incidents include infanticide, injury, deliberate neglect, neglect due to ignorance and poverty, and accidents or poisonings where abuse appears to have been a factor. Child abuse stimulated the medical profession, religious bodies, groups of concerned citizens, and eventually the state to intervene to protect and care for endangered children. These initiatives and the social and moral attitudes they reflected are also examined. Legal definitions and records of court proceedings are evaluated as well so that changes in official as well as social attitudes can be better understood.

Congenital dislocation of the hip: early and late diagnosis and management compared.

During the decade 1970-9, 23 002 infants born in the University of Bristol Department of Obstetrics were examined for congenital dislocation of the hip by junior members of the paediatric staff on the first day of life and again on discharge from hospital. Suspected hip abnormality was checked by a senior member of the staff on the same day. A total of 445 (1.9%) infants were found to have a hip abnormality in the neonatal period. Immediate treatment in an abduction splint was undertaken, usually six weeks for dislocatable hips and 12 weeks for dislocated hips. Routine follow up included clinical and radiological examination at six, 12, 24, and 60 months. Altogether 90% completed the 12 month, 85% the 24 month, and 76% the 60 month checks. Five infants (1.1%) required further orthopaedic treatment (adductor tenotomy and abduction splinting) but no major surgery was necessary, nor was avascular necrosis encountered. The radiological results were excellent. Every effort (1970-84) was also made to identify all cases of late congenital dislocation of the hip diagnosed after the neonatal period in infants born to women in Avon during the same decade (n = 103 431). Ninety one cases were detected (0.88 per 1000 births), 10 in the university cohort (0.44 per 1000) and 81 in the non-university group (1.00 per 1000) (P less than 0.01). Seven of 10 in the former group required open surgery and in seven the radiological outcome at follow up was moderate or poor. The early and late diagnosed groups are compared in respect of perinatal factors and management. It is possible to detect most cases of congenital dislocation of the hip at birth and treat them safely and successfully.
