Effects of psychologic stress on fetal development and pregnancy outcome

Prenatal depression among pregnant women attending public health facilities in Babile district, Eastern Ethiopia: a cross-sectional study

BACKGROUND

Depression during pregnancy is a significant health concern that can lead to a variety of short and long-term complications for mothers. Unfortunately, there is a lack of information available on the prevalence and predictors of prenatal depression in rural eastern Ethiopia. This study assessed prenatal depression and associated factors among pregnant women attending public health facilities in the Babile district, Eastern Ethiopia.

METHOD

An institution-based cross-sectional study was conducted among 329 pregnant women attending Babile District Public Health Facilities from November 1 to December 30, 2021. Bivariable and multivariable logistic regression were used to identify factors associated with prenatal depression. The adjusted odds ratio (AOR) with a 95% confidence interval was used to report the association, and the significance was declared at a p-value < 0.05.

RESULTS

The prevalence of prenatal depression was 33.1% (95% CI = 28.0%, 38.2%). A lower income (AOR = 3.85, 95% CI = 2.08, 7.13), contraceptive use (AOR = 0.53, 95% CI = 0.28, 0.98), unintended pregnancy (AOR = 2.24, 95% CI = 1.27, 3.98), history of depression (AOR = 5.09, 95% CI = 2.77, 9.35), poor social support (AOR = 5.08, 95% CI = 2.15, 11.99), and dissatisfied marriage (AOR = 2.37, 95% CI = 1.30, 4.33) were the factors associated with increased prenatal depression among pregnant women.

CONCLUSIONS

One in every three pregnant women in rural eastern Ethiopia had prenatal depression. Monthly income, contraceptive use, pregnancy intention, history of depression, social support, and marriage satisfaction status were the determinants of prenatal depression. Preventing unintended pregnancies by encouraging women to utilize modern contraceptive methods is essential for mitigating and controlling the risks and burdens of prenatal depression and its negative consequences.

Pregnancy Outcome during the First COVID 19 Lockdown in Vienna, Austria

The COVID 19 pandemic represents a major stress factor for non-infected pregnant women. Although maternal stress during pregnancy increases the risk of preterm birth and intrauterine growth restriction, an increasing number of studies yielded no negative effects of COVID 19 lockdowns on pregnancy outcome. The present study focused on pregnancy outcome during the first COVID 19 lockdown phase in Austria. In particular, it was hypothesized that the national lockdown had no negative effects on birth weight, low birth weight rate and preterm birth rate. In a retrospective medical record-based single center study, the outcome of 669 singleton live births in Vienna Austria during the lockdown phase between March and July 2020 was compared with the pregnancy outcome of 277 live births at the same hospital during the pre-lockdown months of January and February 2020 and, in addition, with the outcome of 28,807 live births between 2005 and 2019. The rate of very low gestational age was significantly lower during the lockdown phase than during the pre-lockdown phase. The rate of low gestational age, however, was slightly higher during the lockdown phase. Mean birth weight was significantly higher during the lockdown phase; the rates of low birth weight, very low birth weight and extremely low birth weight were significantly lower during the lockdown phase. In contrast, maternal gestational weight gain was significantly higher during the lockdown phase. The stressful lockdown phase in Austria seems to have no negative affect on gestational length and newborn weight among non-infected mothers.

Preterm birth, low fetal growth and risk of suicide in adulthood: a national cohort and co-sibling study

BACKGROUND

Adverse perinatal exposures have been associated with psychiatric disorders and suicidal behaviours later in life. However, the independent associations of gestational age at birth or fetal growth with suicide death, potential sex-specific differences, and causality of these associations are unclear.

METHODS

A national cohort study was conducted of all 2 440 518 singletons born in Sweden during 1973-98 who survived to age 18 years, who were followed up through 2016. Cox regression was used to compute hazard ratios (HRs) for suicide death associated with gestational age at birth or fetal growth while mutually adjusting for these factors, sociodemographic characteristics and family history of suicide. Co-sibling analyses assessed the influence of unmeasured shared familial (genetic and/or environmental) factors.

RESULTS

In 31.2 million person-years of follow-up, 4470 (0.2%) deaths by suicide were identified. Early preterm birth (22-33 weeks) was associated with an increased risk of suicide among females [adjusted hazard ratio (HR), 1.97; 95% confidence interval CI), 1.29, 3.01; P = 0.002) but not males (0.90; 0.64, 1.28; P = 0.56), compared with full-term birth (39-41 weeks). Small for gestational age was associated with a modestly increased risk of suicide among females (adjusted HR, 1.27; 95% CI, 1.08, 1.51; P = 0.005) and males (1.14; 1.03, 1.27; P = 0.02). However, these associations were attenuated and non-significant after controlling for shared familial factors.

CONCLUSIONS

In this large national cohort, preterm birth in females and low fetal growth in males and females were associated with increased risks of suicide death in adulthood. However, these associations appeared to be non-causal and related to shared genetic or prenatal environmental factors within families.

The Effects of Carob (Ceratonia siliqua L.) on Emotional Behavior Impairment and Metabolic Disorders Induced by Estrogen Deficiency in Rats

Carob (Ceratonia siliqua L.) contains a wide variety of polyphenols with high antioxidant properties. In this study, we investigated the effects of aqueous extract of carob pods (AECP) on emotional behavior impairments and metabolic disorders in ovariectomized (OVX) rats. Female Wistar rats were assigned to three groups: group 1, control non-OVX rats; group 2, OVX rats; and group 3, OVX rats orally treated with AECP (500 mg/kg) for15 days after ovariectomy. Elevated plus-maze and open-field tests were performed on the 26th and 27th post-ovariectomy days, respectively. Afterwards, the rats were anesthetized and their serums were collected for biochemical analysis. We found that AECP improved emotional behavior impairments revealed by elevated plus-maze and open-field tests in OVX rats. Moreover, ovariectomy significantly increased triglyceride, lactate dehydrogenase, alanine aminotransferase, and aspartate aminotransferase levels in the serum. AECP administration significantly reversed ovariectomy-induced biochemical alterations. Thus, we suggest that the AECP may have an anxiolytic-like effect and prevent biochemical disorders associated with menopause or ovariectomy.

Effects of prenatal exposure to WIFI signal (2.45GHz) on postnatal development and behavior in rat: Influence of maternal restraint

The present study was carried out to investigate the potential combined influence of maternal restraint stress and 2.45GHz WiFi signal exposure on postnatal development and behavior in the offspring of exposed rats. 24 pregnant albino Wistar rats were randomly assigned to four groups: Control, WiFi-exposed, restrained and both WiFi-exposed and restrained groups. Each of WiFi exposure and restraint occurred 2h/day along gestation till parturition. The pups were evaluated for physical development and neuromotor maturation. Moreover, elevated plus maze test, open field activity and stationary beam test were also determined on postnatal days 28, 30 and 31, respectively. After behavioral tests, the rats were anesthetized and their brains were removed for biochemical analysis. Our main findings showed no detrimental effects on gestation progress and outcomes at delivery in all groups. Subsequently, WiFi and restraint, per se and mainly in concert altered physical development of pups with slight differences between genders. Behaviorally, the gestational WiFi irradiation, restraint and especially the associated treatment affected the neuromotor maturation mainly in male progeny. At adult age, we noticed anxiety, motor deficit and exploratory behavior impairment in male offspring co-exposed to WiFi radiation and restraint, and in female progeny subjected to three treatments. The biochemical investigation showed that, all three treatments produced global oxidative stress in brain of both sexes. As for serum biochemistry, phosphorus, magnesium, glucose, triglycerides and calcium levels were disrupted. Taken together, prenatal WiFi radiation and restraint, alone and combined, provoked several behavioral and biochemical impairments at both juvenile and adult age of the offspring.

Prevalence of antenatal depression and associated factors among pregnant women in Addis Ababa, Ethiopia: a cross-sectional study

Background

The World Health Organization identifies depressive disorders as the second leading cause of global disease burden by 2020. However, there is a paucity of studies which examined the associated factors of antenatal depression in low-income countries. This study aimed to determine the prevalence of antenatal depression and associated factors among pregnant women in Addis Ababa, Ethiopia.

Methods

A cross-sectional study was employed among 393 pregnant women attending antenatal care service in Addis Ababa public health centers, Ethiopia from April 12–26, 2012. The Edinburgh Postnatal Depression Scale (EPDS) was used to detect depressive symptoms. Descriptive statistics and logistic regression were used in the statistical analysis.

Results

Prevalence of antenatal depression was 24.94 % (95 % CI: 20.85–29.30 %). In the final multivariable model, those pregnant women who have previous history of depression were nearly three times at higher odds of having antenatal depression as compared to pregnant women who have no history of depression [AOR = 2.57(95 % CI: 1.48–4.48 )]. Those pregnant women having unplanned pregnancy were nearly three times at higher odds to develop depression as compared to pregnant women whose pregnancy was planned [AOR = 2.78(95 % CI: 1.59–4.85)]. The odd of developing antenatal depression was 89 % higher in those pregnant women who experienced lack of baby’s father support [AOR = 1.89(95 % CI: 1.06–3.36)]. Education level, community’s support, and partner’s feeling on current pregnancy were not significantly associated factors with antenatal depression in the final multivariable model.

Conclusion

Although clinical confirmation for antenatal depression is not conducted, one quarter of the pregnant women attending antenatal care were depressed in Addis Ababa based on EPDS. Unplanned pregnancy, experiencing lack of baby’s father support and previous history of depression were factors independently associated with antenatal depression. Promotion of family planning and integration of mental health service with existing maternal health care as well as strengthening the referral system among public health centers were the recalled interventions to prevent antenatal depression in Addis Ababa Public Health Centers.

Changes in PTSD symptomatology and mental health during pregnancy and postpartum

Changes in mental health symptoms throughout pregnancy and postpartum may impact a woman's experience and adjustment during an important time. However, few studies have investigated these changes throughout the perinatal period, particularly changes in posttraumatic stress disorder (PTSD) symptoms. The purpose of this study was to examine longitudinal changes in PTSD, depression, and anxiety symptomatology during pregnancy and postpartum. Pregnant women of ethnically diverse backgrounds receiving services for prenatal care at an outpatient obstetric-gynecology clinic or private physicians' office were assessed by interview on symptoms of PTSD, depression, anxiety, and general stress up to four times, including their first, second, and third trimester, and postpartum visits. Overall, during pregnancy there was a declining trend of PTSD symptoms. For anxiety, there was no overall significant change over time; however, anxiety symptoms were individually variable in the rate of change. For both depression and general stress symptoms, there was a declining trend, which was also variable in the individual rate of change among women during their pregnancy. Visual and post hoc analyses also suggest a possible peak in PTSD symptoms in the weeks prior to delivery. While most mental health symptoms may generally decrease during pregnancy, given the individual variability among women in the rate of change in symptoms, screening and monitoring of symptom fluctuations throughout the course of pregnancy may be needed. Further studies are needed to examine potential spiking of symptoms in the perinatal period.

Perinatal conditions and parental age at birth as risk markers for subsequent suicide attempt and suicide: a population based case-control study

Restricted fetal growth and young maternal age have been associated with increased risk of suicidal behaviour later in life. Research investigating the independent and interacting effects of these risk factors with parental mental health and socio-economic status is scarce. A case-control study was effected through record linkage between Swedish registers. Individuals born 1973-1983 who were hospitalized due to a suicide attempt (n = 17,159) or committed suicide (n = 1,407) were matched to ≤10 controls by sex, month and county of birth. Controlling for parental conditions, significantly increased odds ratios (OR) for suicide attempt were found for low birth weight (OR = 1.12, 95 % CI 1.01-1.25), short birth length (OR = 1.15, 95 % CI 1.08-1.22), short and light for gestational age (OR = 1.23, 95 % CI: 1.10-1.38), short but not light for gestational age (OR = 1.18, 95 % CI: 1.09, 1.29), teenage motherhood (OR = 1.66, 95 % CI 1.53-1.80), young fatherhood (OR = 1.33, 95 % CI 1.27-1.39) and multiparity (OR = 1.40, 95 % CI 1.31-1.50). For completed suicide, increased odds ratios were found for low birth weight (OR = 1.65, 95 % CI 1.16-2.35), teenage motherhood (OR = 1.44, 95 % CI 1.09-1.90) and young fatherhood (OR = 1.20, 95 % CI 1.02-1.41). There was a synergy effect between teenage motherhood and parental psychiatric inpatient care with regard to suicide attempt in offspring [synergy index = 1.53 (95 % CI 1.27-1.84)]. Low birth weight and length, and short and light for gestational age may increase the risk of subsequent suicidal behaviour, and more research is needed to investigate underlying mechanisms. Public health implications from this study include measures to improve pre- and perinatal parental mental health, particularly in teenage pregnancies.

The interplay of variants near LEKR and CCNL1 and social stress in relation to birth size

BACKGROUND

We previously identified via a genome wide association study variants near LEKR and CCNL1 and in the ADCY5 genes lead to lower birthweight. Here, we study the impact of these variants and social stress during pregnancy, defined as social adversity and neighborhood disparity, on infant birth size. We aimed to determine whether the addition of genetic variance magnified the observed associations.

METHODOLOGY/PRINCIPAL FINDINGS

We analyzed data from the Northern Finland Birth Cohort 1986 (n=5369). Social adversity was defined by young maternal age (<20 years), low maternal education (<11 years), and/or single marital status. Neighborhood social disparity was assessed by discrepancy between neighborhoods relative to personal socio-economic status. These variables are indicative of social and socioeconomic stress, but also of biological risk. The adjusted multiple regression analysis showed smaller birth size in both infants of mothers who experienced social adversity (birthweight by -40.4 g, 95%CI -61.4, -19.5; birth length -0.14 cm, 95%CI -0.23, -0.05; head circumference -0.09 cm 95%CI -0.15, -0.02) and neighborhood disparity (birthweight -28.8 g, 95%CI -47.7, -10.0; birth length -0.12 cm, 95%CI -0.20, -0.05). The birthweight-lowering risk allele (SNP rs900400 near LEKR and CCNL1) magnified this association in an additive manner. However, likely due to sample size restriction, this association was not significant for the SNP rs9883204 in ADCY5. Birth size difference due to social stress was greater in the presence of birthweight-lowering alleles.

CONCLUSIONS/SIGNIFICANCE

Social adversity, neighborhood disparity, and genetic variants have independent associations with infant birth size in the mutually adjusted analyses. If the newborn carried a risk allele rs900400 near LEKR/CCNL1, the impact of stress on birth size was stronger. These observations give support to the hypothesis that individuals with genetic or other biological risk are more vulnerable to environmental influences. Our study indicates the need for further research to understand the mechanisms by which genes impact individual vulnerability to environmental insults.

Women's mental health: a "wish-list" for the DSM V

This article highlights four areas of mental health affecting women in the reproductive age group which, in the author's opinion, are poorly dealt with in the Diagnostic and Statistical Manual of Mental Disorders Fourth Edition (DSM IV) (American Psychiatric Association 1994). These are depression occurring during pregnancy; childbirth-related post-traumatic stress disorder; disorders of parent-to-infant attachment and perinatal bereavement. It is suggested that, if these could be better addressed in the forthcoming DSM V, this would provide a very significant impetus for improved education of health professionals, as well as better recognition and earlier intervention in these disorders. As these are relatively common disorders, a very large number of women and their families would potentially benefit.

Evolutionary theory, psychiatry, and psychopharmacology

Darwin's seminal publications in the nineteenth century laid the foundation for an evolutionary approach to psychology and psychiatry. Advances in 20th century evolutionary theory facilitated the development of evolutionary psychology and psychiatry as recognized areas of scientific investigation. In this century, advances in understanding the molecular basis of evolution, of the mind, and of psychopathology, offer the possibility of an integrated approach to understanding the proximal (psychobiological) and distal (evolutionary) mechanisms of interest to psychiatry and psychopharmacology. There is, for example, growing interest in the question of whether specific genetic variants mediate psychobiological processes that have evolutionary value in specific contexts, and of the implications of this for understanding the vulnerability to psychopathology and for considering the advantages and limitations of pharmacotherapy. The evolutionary value, and gene-environmental mediation, of early life programming is potentially a particularly rich area of investigation. Although evolutionary approaches to psychology and to medicine face important conceptual and methodological challenges, current work is increasingly sophisticated, and may prove to be an important foundational discipline for clinicians and researchers in psychiatry and psychopharmacology.
