Potential predictors in neonaticide: the impact of the circumstances of pregnancy

Denial of reproductive potential: a predictor of unperceived pregnancy in an Austrian neonaticide sample

PURPOSE

This study aims to describe the phenomenon of unperceived pregnancy followed by neonaticide with a focus on the lack of awareness of reproductive potential in an Austrian sample.

METHODS

An explorative comparative study of neonaticide cases with single and repeat perpetrators was conducted using nationwide register-based data from 1995 to 2017. A total number of 55 cases out of 66 were included in the analysis. A standardized coding sheet was used and calculations were performed.

RESULTS

48 women gave birth to 101 children, of which 55 were killed, 23 children lived out of home care and 23 lived with the perpetrator We found a higher fertility rate in both neonaticide perpetrators in the single (1,9) and the repeat group (4,25) in comparison to the general population (1,4). The use of contraception was only 31% among neonaticide perpetrators, deviating substantially from the general Austrian population age group (16-29yrs) which used contraception in 91%. The neonaticide perpetrators used an effective contraception method (pearl-index < 4) in only 2%, whereas 20% of the general population did so. The number of unperceived pregnancies was high in both groups (50/55) 91%.

CONCLUSION

Future case reports and forensic evaluations should take reproductive behavior into account, as it may offer valuable insights into the events leading up to neonaticide. Our findings suggest that denial of reproductive potential often precedes unperceived pregnancies. In the Austrian cohort, women who experienced unperceived pregnancies resulting in unassisted births and subsequent neonaticide showed a low prevalence of contraceptive use. This is particularly noteworthy given that the primary motive for neonaticide is unwanted pregnancy.

Ethical Dilemmas and Countertransference in Legally Mandated Reporting of Fatal Child Neglect

In the fall of 2019, a much-publicized court case brought to national attention the issues of patient-doctor confidentiality when it comes to reporting the deaths of newborns in the United States. It is unclear whether the recent overturning of Roe v. Wade will lead to more cases like this. This article discusses issues of countertransference, as well as the ethical and legal implications were it to be a psychiatrist, in active treatment of such a patient, who would be required to make such a report. More specifically, as in the publicized court case, the patient could be a minor at the time, receiving treatment from a child psychiatrist. The implications of such a case include how countertransference affects the perception of fatal child neglect compared to intentional neonaticide; the ethical dilemma of generating a mandated report with the goal of child safety when such a report could lead to real legal consequences for a minor child; and considerations regarding continued treatment of a patient after such a report is made. It is likely that countertransference, shaped by attitudes toward mothers and idealized views on mothering, may play a large role in all these circumstances.

Exceptional Survival of a Buried Alive Newborn: A Case Report

Introduction

This report details the exceptional survival of a female newborn buried alive by her own mother after a clandestine and unassisted birth. Despite spending over six hours underground, the newborn remarkably survived without exhibiting signs of perinatal asphyxia or major complications, and did not require advanced resuscitation measures.

Case Presentation

Rescued following a shocking discovery in a garden and rushed to the hospital, this newborn experienced transient hypothermia, mild to moderate respiratory distress, and scattered skin bruises. After five days of hospital care, she was discharged in clinically stable condition with no infectious complications, displaying age-appropriate normal neurological examination findings and excellent feeding.

Conclusion

This case not only defies established expectations but also illuminates perinatal physiological adaptation complexities. It highlights a fortunate and exceptional outcome in dire circumstances, presenting a captivating enigma within scientific realms. This report sheds light on the critical importance of early intervention and timely rescue efforts in cases of neonaticide, emphasizing the significance of raising awareness and implementing prompt measures to safeguard newborns in vulnerable situations and collectively contribute to our understanding of handling similar distressing cases.

A case report involving the experience of pervasive pregnancy denial: detailed observation of the first 12 postpartum weeks

BACKGROUND

Pervasive pregnancy denial is a rare condition associated with distress and unassisted delivery.

CASE PRESENTATION

The case involves a 38-year-old woman (NN), with two older children (ages 8 and 11), who was unaware, until delivery, that she had been pregnant. The case is discussed in the context of a 12-week observation of postpartum mood, stress, and mother-child attachment. NN and other 558 non-depressed women (mean age 32.41 years) were selected from the pool of participants in the RIPOD (risk of postpartum depression) study. All participants were recruited within 1-6 days of delivery. In addition to surveying depressed mood at childbirth, remote assessments of mood, mother-child attachment, and perceived stress were conducted at 3, 6, 9, and 12 weeks postpartum. Every other day, the participants also reported their current perceived stress levels based on a scale from 1 (low) to 10 (high). During the entire period of postpartum observation, NN reported no symptoms on the Edinburgh Postpartum Depression Scale, similar to only 1.6% of the sample, no stress as 0.7% of the sample, and above-average mother-infant bonding akin to only 4.6% of the sample. Her daily stress levels showed no disturbance, which was the case for only 3.32% of the total sample. On the day of delivery, NN reported a stress level of 1 (the minimum possible level), which was reported by only 4.2% of the total sample. However, NN reported the experience of delivery to be traumatic given that the child had fallen to the floor.

CONCLUSION

The experience of a denied pregnancy did not appear to disturb NN at any time point, not even on the day of delivery. Compared to NN, the other non-depressed participants reported wide fluctuations in stress levels during the observation period. NN did not report any risk factors for denied pregnancy. Thus, she belonged neither to any group of typical pregnancy deniers, as reported in the literature, nor to a typical postpartum group. We postulate, therefore, that the extent to which pregnancy denial can be deemed a normal variation, unrelated to a psychological or physiological condition, depends largely on personal traits.

Towards a new understanding of pregnancy denial: the misunderstood dissociative disorder

Pervasive pregnancy denial is a misunderstood reproductive anomaly which compromises the health of both mother and the developing fetus. Because in extreme cases, the death of the neonate at the hands of his/her mother has criminal repercussions, research has attempted to explain the origins of this clinical phenomenon. The purpose of this review is to analyze the evolution of understanding the association between pregnancy denial and neonaticide. This paper identifies the consistent similarities in symptom presentation, particularly dissociation, when a denied pregnancy ends with the death of the newborn. The common thread across the progression of the literature over time serves as a foundation for considering the development of diagnostic criteria for future inclusion in the Diagnostic and Statistical Manual of Mental Disorders. This paper reviews the seminal research from 1969 to current research up to 2020 addressing pregnancy denial and its connection to neonaticide. Peer reviewed and published articles related to key terms around "pregnancy denial," "pregnancy concealment," "neonaticide," and "dissociation" were retrieved from major databases such as PubMed, PsychINFO, JSTOR, ProQEST, ScienceDirect, and Google Scholar. Reference lists of relevant articles were also scanned to search for further papers pertaining to similarities in symptom presentation across demographic profiles. Papers were excluded if they were not available in English, or if they did not contribute to identifying consistencies in clinical presentation when a pregnancy is denied. There are clear repetitive markers that occur across studies which pertain not only to the frequent absence of certain expected indicators of pregnancy, (i.e. no morning sickness, weight gain, or sensations of fetal movement), but also the misattribution of pregnancy-related symptoms, and the consistent experience of a dissociative episode while giving birth that can unintentionally result in neonaticide. This paper concludes that dissociation is a consistently seen symptom in pervasive pregnancy denial. Dissociation, in addition to other commonly seen symptoms across cases, suggests specific diagnostic criteria that lend themselves to inclusion in the Diagnostic and Statistical Manual of Mental Disorders.

News media representations of women who kill their newly born children

This paper presents a first quantitative analysis of language in media reports of neonaticide and a comparative examination of language use within the reports. One thousand twenty-seven Austrian print media reports from 2004 to 2014 were retrieved; after exclusion, 331 were analysed using the Linguistic Inquiry and Word Count (LIWC) software. After a preliminary analysis, a comparative analysis was carried out between reports on the Graz case and all other cases. The preliminary analysis revealed that a majority of media reports were related to one repeat neonaticide case (Graz) despite not being clinically different from other cases identified for the same period. The comparative linguistic analysis shows some statistically significant differences relating to the domains of emotional words (less words of anxiety, sadness) and family and in the category of insight and certainty (more words). The unexpected media attention on the Graz case and the ensuing verdict, which was in contradiction with the Austrian infanticide act, might have been influenced by the way language was used by journalists and the media. The authors suggest guidelines on sensitive media reporting are required.

Neonaticide rate unchanged in Japan despite a decrease in the birth rate

BACKGROUND

Neonaticide is the murder of a newborn baby within 24 hours of birth. It has been reported in various countries, but there has been little recent research on the current state of neonaticide in Japan.

AIM

To elucidate the epidemiological features of neonaticide in Japan using public long-term, population-based data collected over 14 years and 9 months from July 2003 to March 2018.

METHODS

A descriptive analysis of public data from 2003 to the present was conducted related to deaths which had been retrospectively investigated and deemed by the authorities to be caused by child abuse or neglect.

RESULTS

Between July 2003 and March 2018, there were 149 cases of 'known' neonaticide in Japan and the incidence was 0.96/100,000 live births. The majority of perpetrators were mothers, accounting for 135 (91%) of cases, and in 70 (48%) cases they were young mothers under the age of 25. None of the infants was delivered in a medical facility. Nine (6%) murders were committed by both parents together and only one (1%) by the father alone.

CONCLUSION

The number of births in Japan has been declining gradually but the rate of neonaticide is the same.

Trends of infanticides in northern Tunisia: A 40 years study (1977-2016)

BACKGROUND

The Tunisian Penal Code defines infanticide as the murder committed by the mother on her child at birth or immediately after. There is a dearth of studies and official statistics on infanticide in the Arab region and North Africa.

OBJECTIVE

to analyze the infanticide trends in northern Tunisia between 1977 and 2016.

PARTICIPANTS AND SETTING

we included all cases of infanticides autopsied at the Legal Medicine Department of Charles Nicolle Hospital in Tunis, over a period of 40 years (1977-2016).

METHODS

A descriptive retrospective study.

RESULTS

We collected a total of 513 cases of infanticide over the study period. The general prevalence of infanticide was 0.42 per 100,000 live births per year. Infanticide often occurred during the week, in winter (31.5%) and in spring (30.9%). The newborn was often found on public roads (40.9%) and in urban areas (81.4%). The newborn was often full-term (73.6%), mature, without any congenital malformation, found completely naked (75.2%) and with an empty stomach (93.7%). The umbilical cord was often cut (71.5%), not ligated (82%) with an irregular edge (64%). There was often no putrefaction (54.4%). The hydrostatic test (81.8%) and histological examination (81.1%) showed that infants had breathed. Neglect was the most common cause of death (49.9%).

CONCLUSION

Northern Tunisia has a low prevalence of infanticide compared to most of the previous European and American studies. A better understanding of infanticide would allow us to adapt measures of prevention.

Repeated neonaticide: differences and similarities to single neonaticide events

This study aims to identify differences between single and repeat perpetrators of filicide by using register-based data. The study used register-based, comprehensive, nationwide data from both Austria and Finland. The current study covers 23 perpetrators, 20 single and 3 repeat perpetrators, with a total of 28 victims. All victims had a maximum age of 24 h and all perpetrators were women. Every third victim of neonaticide was a victim of a repeat case. The repeat perpetrators were older; had a higher number of children over their lifespan, some of whom lived with them; were more likely to live within established family structures; had higher levels of education and employment; had a higher proportion of personality disorders; and were more likely to identify stress factors during pregnancy. One unexpected finding was low levels of awareness about pregnancy within the perpetrator's circle remain a risk factor, especially for repeat perpetrators. Arguably, the quality of interpersonal relationships these women have may be affected by their own mental health issues and life experience and vice versa.

Denial of Pregnancy: Psychopathology and Clinical Management

Denial of pregnancy (DOP) is a challenging condition with poorly understood psychopathology. DOP is reported to be associated with problems such as severe psychological conflicts, obstetric complications, risks to the newborn, and difficulties in bonding with the infant. In this paper, we present and discuss the clinical manifestations of a severe form of DOP that lasted until the time of delivery with resultant multifaceted complications. Our paper highlights the severity of psychopathology and the need for coordinated management. Descriptions from different cultural backgrounds would improve the conceptual understanding of DOP.

Regaining agency and autonomy: A grounded typology of concealed pregnancy

AIM

To explore and understand the experience of concealed pregnancy and develop a framework for practitioners.

BACKGROUND

Numerous cases of concealed pregnancy resulting in serious outcomes including maternal and perinatal death, newborn abandonment, and neonaticide are reported internationally. Historically concealed pregnancy is associated with oppressive religious cultures where premarital pregnancy was shunned. Concealed pregnancy has traditionally been viewed through a biomedical lens and associated with mental illness but this assertion remains unsubstantiated by robust evidence.

DESIGN

A Glaserian grounded theory study was undertaken.

DATA SOURCES

Thirty women were interviewed, between 2014 - 2016, on up to three occasions (46 interviews) and 22 cases of public interest were included as data.

METHODS

The constant comparative method and theoretical sampling which are the analytical strategies of grounded theory were used to analyse the data and generate the typology.

RESULTS

Concealed pregnancy is a fearful, life-altering, and traumatic experience. Women with a history of controlling and oppressive relationships characterized by fear respond to a crisis pregnancy by keeping it secret. Many women's relationships were characterized by emotional, mental, sexual, or physical violence. Fear for one's survival is common, may render women unable to access care or support and can be so extreme that a woman may end her own life or give birth alone.

CONCLUSIONS

This typology of concealed pregnancy is intended to aid understanding the fear, trauma, and complexities associated with concealed pregnancy which is vital if practitioners are to provide sensitive, responsive and non-judgemental care.

Y avait-il un père ? Paternité et relations de couple dans les affaires de néonaticides

Cadre de la recherche : Les affaires de néonaticide sont essentiellement connues au travers de la procédure judiciaire qui garde une approche très traditionnelle d’un crime exclusivement féminin et qui ne met en cause que la mère.

Objectifs : Le présent article s’attache à analyser ce qui est décrit de l’attitude du partenaire de la mère vis-à-vis de la paternité, et ce faisant les relations de couple qui y sont attachées.

Méthodologie : À partir de 2306 articles de presse décrivant 357 néonaticides suspectés en France de 1993 à 2012, une analyse thématique a été réalisée, utilisant toutes les mentions au père de l’enfant.

Résultats : Trois grandes tendances ont été mises en exergue : l’homme qui a conçu cet enfant, soit n’est pas envisagé dans ce rôle de père, car il est écarté de la paternité par la mère ou par la justice, soit ne veut pas être père, soit veut être père, mais en est empêché par la mère.

Conclusions : Contrairement à la littérature sur la parentalité aujourd’hui, les affaires de néonaticide mettent en scène une vision stéréotypée où la mère est seule à répondre du désir d’enfant. Ainsi, lors des poursuites judiciaires pour néonaticide, la présence du père est déniée, refusée, que le désir paternel existe ou non.

Contribution : Cet article fait le point sur l’existence donnée au père dans le contexte des poursuites judiciaires des mères à partir d’un corpus de presse concernant 141 mères ayant été poursuivies pour nénonaticide.

Acute dissociative reaction to spontaneous delivery in a case of total denial of pregnancy: Diagnostic and forensic aspects

This article presents the history of a 21-year-old female college student with total denial of pregnancy who experienced an acute dissociative reaction during the spontaneous delivery at home without medical assistance where the newborn died immediately. Psychiatric examination, self-report questionnaires, legal documents, and witness reports have been reviewed in evaluation of the case. Evidence pointed to total denial of pregnancy, that is, until delivery. The diagnoses of an acute dissociative reaction to stress (remitted) and a subsequent PTSD were established in a follow-up examination conducted 7 months after the delivery. Notwithstanding the inherently dissociative nature of total denial of pregnancy, no other evidence has been found about pre-existing psychopathology. For causing the newborn's death, the patient faced charges for "aggravated murder," which were later on reduced into "involuntary manslaughter." Given the physical incapacity to perform voluntary acts due to the loss of control over her actions during the delivery, and the presence of an acute dissociative reaction to unexpected delivery, the legal case represents an intricate overlap between "insanity" and "incapacitation" defenses. The rather broad severity spectrum of acute dissociative conditions requires evaluation of the limits and conditions of appropriate legal defenses by mental health experts and lawyers. Denial of pregnancy as a source of potential stress has attracted little interest in psychiatric literature although solid research exists which documented that it is not infrequent. Arguments are presented to introduce this condition as a diagnostic category of female reproductive psychiatry with a more neutral label: "unperceived pregnancy."

Homicide in the western family and background factors of a perpetrator

AIMS

Familicide is a multiple-victim homicide incident in which the killer's spouse and one or more children are slain. A systematic review was conducted to reveal the background factors of western homicide perpetrators.

METHODS

The systematic search was performed in the Arto, Medic, Cinahl, Medline, EBSCOhost Academic Search Premier and Social Services abstracts databases. The keywords were familicide, family homicide, familicide-suicide, filicide-suicide, extended suicide, child, murder, family, filicide and infanticide. The searches revealed 4139 references from the databases. The references were filtered and 32 peer-reviewed research articles revealed in years 2004-2014 were selected as data. The articles were analysed using inductive content analysis, by finding all possible background factors related to homicide.

RESULTS

The factors were described as percentages of the range. The background factors of familicide perpetrators were categorised as follows: perpetrators who had committed homicide of a child and intimate partner and possibly committed suicide; a father had who killed a child; a mother who had killed a child; a father who had committed a filicide-suicide; and a mother who had committed a filicide-suicide.

CONCLUSIONS

Psychological instability, violence and crime were found in all these categories of familicides. Perpetrators who had committed a suicide in addition to the familicide had more often been diagnosed with depression, but they sought treatment for mental health problems less often and had violence and self-destructiveness less often in their background than in other familicide categories. Social and healthcare professionals should be more sensitive to emerging family problems and be prepared for intervention.

The worldwide incidence of neonaticide: a systematic review

Neonaticide is the killing of a neonate on the day of its birth by his/her own mother. Neonaticidal women were reported to be predominantly young, unmarried, and primiparous. The motive for murdering the newborn relates to the shame, the fear of rejection, and abandonment by significant others, and the social stigmas associated with an illegitimate birth. The goal of the present study was to conduct a systematic review of the scientific literature and identify population-based studies reporting the incidence of neonaticide in different countries. A total of 485 abstracts were screened. After applying the inclusion/exclusion criteria, 10 studies were selected. Additional searches identified two more articles. Most of these studies were from Europe, where incidence varied from 0.07 (Finland, 1980-2000 period) to 8.5 neonaticides per 100000 births (Austria, 1975-2001 period). More recent studies have indicated that a growing proportion of neonaticidal women are married, multiparous, and suffers from mental disorders. Preventive measures, such as anonymous free delivery, were shown to reduce the incidence of neonaticide, although this effect may be short-lived. Despite social and institutional changes, neonaticide persists even in the most socially advanced, liberal, and prosperous societies in the world.

Gender Differences in Homicide of Neonates, Infants, and Children under 5 y in South Africa: Results from the Cross-Sectional 2009 National Child Homicide Study

BACKGROUND

Homicide of children is a global problem. The under-5-y age group is the second largest homicide age group after 15-19 y olds, but has received little research attention. Understanding age and gender patterns is important for assisting with developing prevention interventions. Here we present an age and gender analysis of homicides among children under 5 y in South Africa from a national study that included a focus on neonaticide and infanticide.

METHODS AND FINDINGS

A retrospective national cross-sectional study was conducted using a random sample of 38 medico-legal laboratories operating in 2009 to identify homicides of children under 5 y. Child data were abstracted from the mortuary files and autopsy reports, and both child and perpetrator data data were collected from police interviews. We erred towards applying a conservative definition of homicide and excluded sudden infant death syndrome cases. We estimated that 454 (95% CI 366, 541) children under the age of 5 y were killed in South Africa in 2009. More than half (53.2%; 95% CI 46.7%, 59.5%) were neonates (0-28 d), and 74.4% (95% CI 69.3%, 78.9%) were infants (under 1 y), giving a neonaticide rate of 19.6 per 100,000 live births and an infanticide rate of 28.4 per 100,000 live births. The majority of the neonates died in the early neonatal period (0-6 d), and abandonment accounted for 84.9% (95% CI 81.5%, 87.8%) of all the neonates killed. Distinct age and gender patterns were found, with significantly fewer boy children killed in rural settings compared to urban settings (odds ratio 0.6; 95% CI 0.4, 0.9; p = 0.015). Abuse-related killings and evidence of sexual assault were more common among older girls than in all other age and gender groups. Mothers were identified as the perpetrators in all of the neonaticides and were the most common perpetrators overall (71.0%; 95% CI 63.9%, 77.2%). Abandoned neonates were mainly term babies, with a mean gestational age of 38 wk. We did not have information on abandonment motives for all newborns and did not know if babies were abandoned with the intention that they would die or with the hope that they would be found alive. We therefore considered all abandoned babies as homicides.

CONCLUSIONS

Homicide of children is an extreme form or consequence of violence against children. This national study provides one of the first analyses of neonaticide and infanticide by age and gender and shows the failure of reproductive and mental health and social services to identify and help vulnerable mothers. Multi-sectoral prevention strategies are needed.

Anonymous birth law saves babies--optimization, sustainability and public awareness

The aims of this study are to assess the impact of Austria's anonymous birth law from the time relevant statistical records are available and to evaluate the use of hatches versus anonymous hospital delivery. This study is a complete census of police-reported neonaticides (1975-2012) as well as anonymous births including baby hatches in Austria during 2002-2012. The time trends of neonaticide rates, anonymous births and baby hatches were analysed by means of Poisson and logistic regression model. Predicted and observed rates were derived and compared using a Bayesian Poisson regression model. Predicted numbers of neonaticides for the period of the active awareness campaign, 2002-2004, were more than three times larger than the observed number (p = 0.0067). Of the 365 women who benefitted from this legislation, only 11.5% chose to put their babies in a baby hatch. Since the law was introduced, a significant decreasing tendency of numbers of anonymous births (p = 047) was observed, while there was significant increase of neonaticide rates (p = 0.0001). The implementation of the anonymous delivery law is associated with a decrease in the number of police-reported neonaticides. The subsequent significantly decreasing numbers of anonymous births with an accompanying increase of neonaticides represents additional evidence for the effectiveness of the measure.

Concealed pregnancy: a concept analysis

AIM/DESIGN

A concept analysis of concealed pregnancy was undertaken using Walker and Avant's framework to examine the attributes, characteristics and uses of the concept in maternity care.

BACKGROUND

Understanding the concept of concealed pregnancy is critical as failing to do so adds the risk of maternal and neonatal morbidity and mortality. Reviewing the literature and selected empirical referents indicated that concealed pregnancy has been predominantly viewed through a biomedical lens. Confusion exists around the definitions of denied and concealed pregnancy.

DATA SOURCES

A systematic search of five bibliographic databases using keywords from the years 1960-2014.

METHODS

Walker and Avant's framework was used to guide the concept analysis. A thematic analysis of reviewed papers identified the main characteristics of concealed pregnancy.

RESULTS

Concealed pregnancy was conceptualized as a process and the critical attributes are secrecy, hiding, daytime story, staying away and avoidance. This process involves avoidance and if this includes failing to access healthcare can lead to catastrophic outcomes such as maternal and neonatal death. Antecedents, attributes and consequences of concealed pregnancy are also identified.

CONCLUSIONS

Understanding the concept of concealed pregnancy and its antecedents, attributes and consequences may assist in risk identification of women who conceal a pregnancy. This concept analysis has identified a need for further exploration of the coping styles and psychosocial processes involved in women concealing and revealing a pregnancy.

Prevalence and phenomenology of neonaticide in Switzerland 1980-2010: a retrospective study

For a child, the likelihood of being murdered is highest during the first year of life, and many such cases are neonaticides. Although several recent studies have examined neonaticide in different countries and cultures, there has been no in-depth analysis of Swiss cases, even though this country has special neonaticide legislation and four "baby hatches" have been opened to prevent such killings. The primary objective of this retrospective study was to analyze the prevalence and phenomenon of neonaticide in Switzerland. Using data from judicial files, 11 cases were identified in 15 German-speaking cantons between 1980 and 2010. The sample included two uncommon cases of nonmaternal neonaticide. The discussion addresses possible prevention strategies.

Is the introduction of anonymous delivery associated with a reduction of high neonaticide rates in Austria? A retrospective study

OBJECTIVE

To assess rates of neonaticide after the implementation of a preventative 'anonymous delivery' law in mid-2001 in Austria. Women are allowed to access antenatal care and give birth in a hospital anonymously, without showing any ID and free of charge.

DESIGN

Retrospective study.

SETTING

A complete census of police-reported neonaticides was obtained from the police statistics of Austria, Sweden and Finland.

POPULATION

All neonaticides reported to the police, 1991-2009.

MAIN OUTCOME MEASURES

Neonaticide rates before (1991-2001) and after (2002-2009) the introduction of anonymous delivery legislation per 100 000 births.

METHODS

The Mann-Whitney U-test for two independent samples was used to compare neonaticide rates in the period before the new law was introduced with the rates observed after the implementation of the new law for each country.

RESULTS

On average the rate of police-reported neonaticides was 7.2 per 100 000 births (SD 3.5, median 7.1) in Austria prior to the new law being passed, and 3.1 per 100 000 births (SD 2.1, median 2.6) after the law was passed. A significant decrease in neonaticide was observed in Austria after the implementation of anonymous delivery (Mann-Whitney U-test P = 0.017). Whereas the Finnish and Swedish rates were lower than the Austrian rates before and after the implementation of the Austrian law, they remained unchanged over the study period.

CONCLUSIONS

Our data demonstrate a significant decrease in the number of police-reported neonaticides in Austria after the implementation of anonymous delivery. Even though underlying factors associated with neonaticide are complex, the findings could indicate an effect of anonymous delivery in the prevention of this crime.
