Perinatal, obstetric and parental risk factors for asthma in the offspring throughout childhood: a longitudinal cohort study.

OBJECTIVES: Asthma is a common chronic and burdensome disease which typically begins in childhood. The aim of this study was to assess perinatal and obstetric factors which may increase the risk of developing asthma in the offspring. METHODS: Data from five consecutive waves (n=7,073 children, from birth to 15 years old) from a nationally-representative birth cohort of people born in the United Kingdom between 2000 and 2002, the Millennium Cohort Study (MCS), were used. The Kaplan-Meier survival curve was used to graphically display the risk of developing asthma from early childhood to adolescence. The Z-based Wald test was used to prove significant covariate loading. RESULTS: Cox regression analyzing the influence of covariates on asthma development risk showed a significant likelihood ratio test, χ2(18)=899.30, p<0.01. A parent with asthma (OR=2.02, p<0.01), a younger maternal age at delivery (OR=0.98, p<0.05), and the use of assisted reproductive technology (OR=1.43, p<0.05) were associated with an increased risk of developing asthma in the offspring. CONCLUSIONS: Perinatal factors (a younger maternal age, assisted reproductive technology) and a parental factor (a parent with asthma) increased the risk for developing asthma in the offspring.

Pandemic-related stress in pregnant women during the first COVID-19 lockdown and neonatal development.

BACKGROUND: Maternal stress and psychopathology have a negative effect on mothers and neonates. Maternal stress may affect neonatal growth and development both physically and psychologically. PURPOSE: To study the impact of pandemic-related pregnancy stress and maternal psychopathological symptoms during the COVID-19 lockdown in 2020 on neonatal development. METHODS: A two-phase prospective study was carried out on a sample of 181 pregnant women ranged from 18 to 40 years old in Spain (Europe). Phase 1: Pandemic-related pregnancy stress (PREPS), Prenatal Distress Questionnaire (PDQ), Perceived Stress Scale (PSS) and the revised version of the Symptom Checklist-90 (SCL-90-R) were used to assess psychological symptoms during the lockdown. In the follow-up (Phase 2), obstetric, birth-related and anthropometric variables were collected from 81 pregnant women-neonates dyads. RESULTS: Primiparous women showed higher psychopathological symptoms and higher levels of pandemic-related pregnancy stress than multiparous women. A multiple linear regression model showed that pandemic-related pregnancy stress could predict the length of neonate by adjusting for maternal age and gestational age, especially for primiparous women. IMPLICATIONS FOR RESEARCH: Studies assessing neonates development should evaluate the long-term effect of the COVID-19 pandemic on neonates´ length. IMPLICATIONS FOR PRACTICE: States the relation between pandemic-related pregnancy stress and neonatal development by being able to track the effects on neonates whose mothers had high levels of stress during the COVID-19 pandemic.

The COVID-19 Pandemic and Psychopathological symptoms in pregnant women in Spain.

BACKGROUND: During the COVID-19 pandemic, pregnant women are exposed to potentially harmful stressors that might affect their health. The direct consequences that SARS-CoV-2 may have on perinatal mental health are still unknown. OBJECTIVE: The present study aimed to explore the impact of the COVID-19 pandemic on psychopathological symptoms in a sample of Spanish pregnant women. METHODS: A sample of 186 pregnant women was assessed using the revised Symptoms Check List-90 during the first lockdown in Spain. RESULTS: The results showed clinical scores on the obsession and compulsion, anxiety and phobic anxiety subscales, as well as on the severity indexes. Phobic anxiety was the only variable that was inversely correlated with age and the number of previous miscarriages. A linear regression model showed that age was inversely associated with phobic anxiety scores. A younger age was associated with higher levels of phobic anxiety symptoms. CONCLUSIONS: Our results indicated that younger pregnant women and women in the first trimester of pregnancy were more vulnerable to the effects of stress and concerns about COVID-19.

Cortisol levels versus self-report stress measures during pregnancy as predictors of adverse infant outcomes: a systematic review.

Systematically review existing evidence to (1) identify the association between self-report stress and cortisol levels measured during pregnancy; and, (2) assess their association with adverse infant outcomes to determine which is the better predictor. A systematic review was conducted in accordance with PRISMA guidelines. Search terms focused on pregnancy, psychological stress and cortisol. Nine electronic databases were searched, in addition to reference lists of relevant papers. Eligibility criteria consisted of studies that included measurement of self-reported psychological stress, cortisol and assessed their associations with any infant-related outcome. Further limits included studies published in English or Spanish with human female participants. A meta-regression was not feasible due to differences in study samples, measurement tools employed, types of cortisol assessed and outcomes reported. A narrative synthesis was provided. 28 studies were eligible for inclusion. Convergent validity between self-report measures and cortisol was reported by three studies (range r = 0.12-0.41). Higher levels of self-report stress were significantly associated with intrauterine growth restriction (fetal biparietal diameter, low fetal head circumference, abdominal circumference), low gestational age at birth, low anthropometric measures (birth length, head circumference, length of the neonate), poor infant neurodevelopment (cognitive development) and potentially pathogenic gut microbiota (Clostridiaceae Clostridium, Haemophilus) in six studies. Higher cortisol levels were significantly associated with intrauterine growth restriction (fetal biparietal diameter, low fetal head circumference, abdominal circumference), low gestational age at birth, low infant birth weight, poor infant neurodevelopment (attention scores on the Network Neurobehavioral Scale) and low levels of potentially protective gut microbiota (Lactobacillus, Slackia and Actinobaculum) in 13 studies. Of the studies that assessed which type of measure was a better predictor of infant outcomes (n = 6), there was agreement that cortisol levels were statistically better at predicting adverse outcomes than self-reported stress. Self-report stress measures appear to be modest predictors of adverse infant outcomes in comparison to cortisol. A number of methodological limitations need to be addressed in future studies to help understand the relationship between cortisol and self-reported stress and how they are related to adverse infant outcomes.

Spanish validation and factor structure of the Prenatal Distress Questionnaire Revised (NuPDQ).

BACKGROUND: Due to an absence of maternal stress being measured in routine prenatal care by clinicians, prenatal stress has become a serious problem which is associated with poorer obstetric outcomes, as well as worse maternal and infant health. For that reason, the aim of this study was the translation, validation and adaptation of Prenatal Distress Questionnaire Revised (NuPDQ) in a Spanish sample. METHODS: Three-hundred and seventy-one pregnant women were assessed using the NuPDQ, the Prenatal Distress Questionnaire, Perceived Stress Scale and the Connor-Davidson Resilience Scale. The NuPDQ was translated into Spanish by the backtranslation method and administered to participants. RESULTS: A confirmatory factor analysis revealed the established unidimensional structure to be a poor fit to data with the Spanish version. An exploratory factor analysis suggested a five-factor structure with 14 items. The instrument had good reliability, convergent and discriminant validity psychometric properties. CONCLUSIONS: The five-factor 14-item NuPDQ is useful to assess pregnancy-specific stress in Spanish pregnant women. It may be appropriate to use this instrument in order to identify pregnant women with high pregnancy-specific stress to try to prevent negative consequences derived from those high levels.

Maternal and Neonatal Hair Cortisol Levels and Psychological Stress Are Associated With Onset of Secretory Activation of Human Milk Production.

BACKGROUND: Several factors can influence the production of mothers' own milk. PURPOSE: To assess the influence of maternal psychological stress, maternal cortisol levels, and neonatal hair cortisol levels on timing of secretory activation. METHODS: A prospective study was conducted at 2 public health centers in Andalusia, Spain. Participants were 60 pregnant women and their 60 neonates. Hair cortisol levels and psychological stress (pregnancy-specific stress [Prenatal Distress Questionnaire, PDQ] and perceived stress [Perceived Stress Scale, PSS]) were evaluated during the third trimester and the postpartum period. This study was part of the GESTASTRESS cohort study on the effects of stress during pregnancy. RESULTS: Higher PDQ and PSS scores (P < .05) in the third trimester were associated with later onset of secretory activation. Higher postpartum maternal hair cortisol levels were associated with a delayed secretory activation of mother's own milk (P < .05). IMPLICATIONS FOR RESEARCH: Future studies should look at the influence of psychological stress and cortisol levels on hormones involved in mother's own milk production. IMPLICATIONS FOR PRACTICE: Neonatal nurses and other healthcare providers should be familiar with levels of neonates' exposure to maternal prenatal stress prior to birth.

Psychometric validation of the Prenatal Distress Questionnaire (PDQ) in pregnant women in Spain.

The Prenatal Distress Questionnaire (PDQ) was developed among English-speaking women in the United States to assess specific worries and concerns during pregnancy. Our aim was to analyze the factor structure of the PDQ, using confirmatory factor analysis, and assess its convergent validity in Spanish women. A sample of 233 pregnant women with ages ranging from 19 to 42 years in the south of Spain (Europe) (January 2015 - March 2016) completed the translated PDQ, the Perceived Stress Scale (PSS) and the Symptom Checklist-90-revised (SCL-90-R). Confirmatory factor analysis revealed a three-factor structure supporting the original PDQ factor structure (χ2 (31) = 55.43, p = 0.004; CFI = 0.96; RMSEA = 0.058; WRMR = 0.702). The Spanish PDQ significantly correlated with the PSS and SCL-90-R (r's 0.18-0.49, p's < 0.05), providing evidence of convergent validity. These results illustrate that the stress dimensions investigated by the PDQ adequately represent pregnant women's distress across a different cultural context and corroborate the psychometric properties of this instrument previously demonstrated in English-speaking women. The Spanish version of the PDQ can be used by clinical practitioners to evaluate specific worries and concerns women experience during pregnancy.

Maternal hair cortisol levels affect neonatal development among women conceiving with assisted reproductive technology.

Objective: To compare stress levels throughout pregnancy in women who had conceived using assisted reproductive technology (ART) and women who had conceived naturally and somatometric values for infants. Background: Pregnant women who have received ART are exposed to high levels of stress. Methods: Ninety-one women attending a prenatal appointment at a Health Centre (Granada, Spain), and their 91 newborns participated in this study: 69 women conceiving naturally and 22 conceiving using ART. Assessment consisted of measuring hair cortisol levels, the Prenatal Distress Questionnaire, the Perceived Stress Scale and the Symptom Checklist-90-Revised. Results: Women conceiving using ART had higher cortisol levels in the first trimester than women who conceived naturally. In the third trimester, women who used ART reported higher levels of perceived stress than those who had conceived naturally. Maternal cortisol levels in the first trimester explained 32% of the variance in neonatal head circumference in the group of women who had conceived using ART. Conclusions: Women who had conceived using ART showed higher levels of cortisol in the first trimester and higher levels of perceived stress in the third trimester than women who had conceived naturally, rendering them more vulnerable to adverse outcomes. Maternal cortisol predicted the infants' development.

Listening to Relaxing Music Improves Physiological Responses in Premature Infants: A Randomized Controlled Trial.

BACKGROUND: Premature infants are exposed to high levels of noise in the neonatal intensive care unit (NICU). PURPOSE: This study evaluated the effect of a relaxing music therapy intervention composed by artificial intelligence on respiratory rate, systolic and diastolic blood pressure, and heart rate. METHODS: A double-blind, randomized, controlled trial was conducted in the NICUs of 2 general public hospitals in Andalusia, Spain. Participants were 17 healthy premature infants, randomly allocated to the intervention group or the control group (silence) at a 1:1 ratio. To be included in the study, the subjects were to be 32 to 36 weeks of gestation at birth (M= 32.33; SD = 1.79) and passed a hearing screening test satisfactorily. The intervention lasted 20 minutes, 3 times a day for 3 consecutive days, while infants were in the incubator. Infants' heart rate, respiratory rate, and blood pressure were assessed before and after each intervention session. RESULTS: After each session, the respiratory rate decreased in the experimental group (main between-groups effect (F1,13 = 6.73, P = .022, ηpartial = 0.34). Across the sessions, the heart rate increased in the control group (main between-groups effect, F1,11 = 5.09, P = .045, ηpartial = 0.32). IMPLICATIONS FOR RESEARCH: Future studies can use this music intervention to assess its potential effects in premature infants. IMPLICATIONS FOR PRACTICE: Nurses can apply the relaxing music intervention presented in this study to ameliorate the impact of the stressful environment on premature infants.

Psychological assessment among immigrant and Spanish women during the postpartum period in Spain.

OBJECTIVE: to describe whether there were differences in sociodemographic, obstetric, perinatal and psychological variables between immigrant women and native-born women in Spain during the first 24 h after delivery. BACKGROUND: The immediate postpartum period is a critical time when physical and psychological disorders are likely to occur. Immigrant women have, in general, poor perinatal and psychological results during this time. METHODS: One hundred and three women at the Virgen de las Nieves University Hospital (Granada, Spain) were divided into two groups: 50 Spanish and 53 immigrants. The instruments used were the Life Orientation Test, the Stress Vulnerability Inventory, the Perceived Stress Scale and the Symptom Checklist-90-Revised (SCL-90-R). Sociodemographic and obstetric data were obtained from the healthcare providers reports. RESULTS: During the postpartum period, the immigrant women had higher mean scores on the following subscales: interpersonal sensitivity (F(1,102) = 4.06; p < 0.05); depression (F(1,102) = 7.24; p < 0.01); phobic anxiety (F(1,102) = 4.83; p < 0.05), paranoid ideation (F(1,102) = 7.20; p < 0.01); and psychoticism (F(1,102) = 4.04; p < 0.05). When considering age, education, profession, job situation, immigrant status of the partner and duration of time in Spain as covariates, differences between groups were significant on obsessive-compulsiveness (F(1,102) = 5.37; p < 0.05) and depression (F(1,102) = 6.89; p < 0.05). CONCLUSIONS: Immigrant women are in need of more psychological and emotional support from their families, midwives and the rest of healthcare providers than are native Spaniards immediately after delivery.

Inflammatory biomarkers and perinatal depression: A systematic review.

BACKGROUND: Approximately 10 to 20% of pregnant women worldwide experience perinatal depression (PND), a depressive episode with onset during pregnancy or after childbirth. We performed a systematic review to identify, summarize and discuss studies on inflammatory biomarkers described in relation to PND. METHOD: Inclusion criteria defined the selection of observational studies written in English, French, Spanish or Portuguese, that evaluate analytical levels of inflammatory molecules (protein levels) in biological fluids in women, with a diagnosis of depression using ICD/DSM diagnostic criteria or depressive symptoms assessed by standardized psychometric instruments, during pregnancy and/or postpartum. Case reports, experimental studies, reviews, qualitative analysis, meta-analysis, gray literature or replicated data were excluded. Three electronic databases were used for search (Pubmed, Web of Science and PsychInfo) and quality assessment of selected studies were performed using the Newcastle-Ottawa Scale. Data extraction included study design; number of subjects; obstetric information; tools and timepoints of depression and inflammatory markers assessment. RESULTS: 56 studies (sample size for cross-sectional and case-control studies ranging from 10 to 469; sample size for longitudinal studies ranging from 26 to 467), where the major aim was to analyze the association between depression and inflammatory biomarkers during pregnancy and postpartum period were included in this systematic review. Overall, the findings of our systematic review lend support to the hypothesis that several inflammatory markers may be associated with peripartum depressive symptoms. The associations were somewhat different looking at pregnancy compared to the delivery time-point and postpartum, and mainly referred to increased levels of IL-6, IL-8, CRP and TNF-α among depressed. DISCUSSION: In summary, our systematic review findings provide evidence supporting the hypothesis that several inflammatory markers may correlate with peripartum depressive symptoms. However, our work also highlighted notable differences in the timing of biological sampling for inflammatory markers and in the methodologies used to assess depression during the perinatal period. Additionally, variations were observed in how inflammatory biomarkers and depression were approached, including their classification as exposure or outcome variables, and the timing of assessments. It is essential for future research to investigate the influence of biological fluids and the timing of assessments for both inflammatory biomarkers and depression to gain a deeper understanding of their association. This comprehensive exploration is pivotal for elucidating the intricate relationship between inflammation and perinatal depression.

Assessment of Postpartum Stress Using the Maternal Postpartum Stress Scale (MPSS) in Spanish Women.

Although scales that evaluate postpartum stress exist, they lack specificity in maternal postpartum stress. The MPSS was created because there was a need to assess maternal stress during the postpartum stage. The introduction of the MPSS has enriched the evaluation tools for postpartum stress and has helped understand maternal stress at various postpartum time points and identify women at high risk for postpartum stress during this period. The aim was to translate the MPSS into Spanish and study its psychometric properties. Postpartum women (N = 167) with a mean age of 34.26 (SD = 4.71) were involved in this study. In addition to the MPSS, a battery of instruments was administered: a demographic sheet, the Birth Satisfaction Scale-Revised (BSS-R) and the Edinburgh Postnatal Depression Scale (EPDS). The MPSS data were analyzed, checking item communality first. As a result, three items showed unsatisfactory communality values (h2 < 0.40). Confirmatory Factor Analysis was conducted, comparing factor models using the full pool of MPSS items or the version without items with unacceptable communality. As a result, the original three-factor structure was endorsed on the Spanish MPSS, with better fit indices when removing items with low communality (RMSEA = 0.067, CFI = 0.99, TLI = 0.99). The reliability of this version was satisfactory (ω = 0.93). Finally, group comparisons for some perinatal variables were performed, showing no significant differences between groups of interest (p = 0.05 and above). To conclude, the MPSS will contribute to the existing literature, having a wider capacity to assess perinatal mental health difficulties in Spanish-speaking populations.

Allostatic Load and Depression Symptoms in Cancer Survivors: A National Health and Nutrition Examination Survey Study.

BACKGROUND: Individuals with cancer often experience stress throughout the cancer trajectory and have a high risk of experiencing depression. OBJECTIVE: The aim of this study was to examine the relationship between allostatic load (AL), a measure of cumulative stress-related physiologic dysregulation of different body systems, and symptoms of depression in cancer survivors. METHODS: Participants were 294 adult cancer survivors from the US National Health and Nutrition Examination Survey (NHANES 2007-2018). Allostatic load was measured using 14 indicators representing cardiometabolic risk, glucose metabolism, cardiopulmonary functioning, parasympathetic functioning, and inflammation. Depressive symptoms were measured with the Patient Health Questionnaire-9. The relationship between AL and depressive symptoms was investigated using multiple regression adjusted for diverse sociodemographic and diagnosis variables. RESULTS: Higher AL was associated with higher depressive symptom scores. The higher risk of depression was concentrated among those survivors in the highest AL quartile, with 21% (95% confidence interval, 11%-32%) of survivors presenting a high risk of depression compared with 8% to 11% of survivors in the lower quartiles. In exploratory analyses, the relationship between AL and depressive symptoms was only significant among survivors with a lower income. In contrast, in survivors in the highest income group, depressive symptoms were lower and unrelated to AL. CONCLUSION: High AL is associated with more depressive symptoms among cancer survivors. IMPLICATIONS FOR PRACTICE: Nurses have an important role in identifying psychological distress in cancer patients and survivors. Further research is needed to investigate the usefulness of AL as a marker in the context of cancer follow-up care and screening for psychological distress.

Maternal Psychopathological Profile during Childbirth and Neonatal Development during the COVID-19 Pandemic: A Pre-Posttest Study.

The coronavirus SARS-CoV-2 generated an alert that became a state of emergency in health issues worldwide, a situation that affected the entire population, including pregnant women. The present study aims to understand the effect of the psychopathological profile of a sample of pregnant women at the time of the COVID-19 pandemic on themselves during childbirth (Phase 1) and after childbirth and the anthropometric measures of the neonate at birth (Phase 2). The total sample comprises 81 pregnant women aged 32.07 years (SD = 5.45) and their neonates. Sociodemographic and obstetric data of the sample were collected. During pregnancy, psychopathology was measured by means of the SCL-90, as well as other psychological measures on stress and social support. Cluster k-means techniques were used to uncover the heterogeneous profiles of psychopathology in Phase 1. Two main psychopathological profiles were found (Cluster 1: High psychopathological symptoms; Cluster 2: Low psychopathological symptoms). The clusters generated show significant differences in all the SCL-90-R subscales used and in the general index at Phase 1. After childbirth, high psychopathology profile membership was associated with a greater probability of having a non-eutocic delivery. On the other hand, the low psychopathological symptoms cluster shows higher levels of depressive symptoms, hostility, paranoid ideation, and psychotic symptoms in Phase 2. In conclusion, there seemed to exist two heterogeneous profiles of psychopathology in pregnant women during the pandemic; the stress related to the pandemic seemed uninfluential on the development of a profile of high psychopathological symptoms and the psychopathology profile may influence delivery and postpartum outcomes.

The impact of COVID-19 on breastfeeding rates: An international cross-sectional study.

BACKGROUND: Breastfeeding promotes children's health and is associated with positive effects to maternal physical and mental health. Uncertainties regarding SARS-CoV-2 transmission led to worries experienced by women and health professionals which impacted breastfeeding plans. We aimed to investigate the impact of self-reported and country-specific factors on breastfeeding rates during the COVID-19 pandemic. METHODS: This study is part of a broader international prospective cohort study about the impact of the COVID-19 pandemic on perinatal mental health (Riseup-PPD-COVID-19). We analysed data from 5612 women, across 12 countries. Potential covariates of breastfeeding (sociodemographic, perinatal, physical/mental health, professional perinatal care, changes in healthcare due to the pandemic, COVID-19 related, breastfeeding support, governmental containment measures and countries' inequality levels) were studied by Generalized Linear Mixed-Effects Models. RESULTS: A model encompassing all covariates of interest explained 24% of the variance of breastfeeding rates across countries (first six months postpartum). Overall, first child (ß = -0.27), age of the child (ß = -0.29), preterm birth (ß = -0.52), admission to the neonatal/pediatric care (ß = -0.44), lack of breastfeeding support (ß = -0.18), current psychiatric treatment (ß = -0.69) and inequality (ß = -0.71) were negatively associated with breastfeeding (p < .001). Access to postnatal support groups was positively associated with breastfeeding (ß = 0.59; p < .001). In countries with low-inequality, governmental measures to contain virus transmission had a deleterious effect on breastfeeding (ß = -0.16; p < .05) while access to maternity leave protected breastfeeding (ß = 0.50; p < .001). DISCUSSION: This study shows that mother's COVID-19 diagnosis and changes in healthcare and birth/postnatal plans did not influence breastfeeding rates. Virtual support groups help women manage breastfeeding, particularly when their experiencing a first child and for those under psychiatric treatment. The complex associations between covariates and breastfeeding vary across countries, suggesting the need to define context-specific measures to support breastfeeding.

Diagnosis and Challenges in Perinatal Health.

Perinatal health is a primary objective for health systems [...].
