Psychosocial distress during pregnancy and the risk of infantile colic: a follow-up study

Infant crying problems related to maternal depressive and anxiety symptoms during pregnancy: a prospective cohort study

Background

Infant crying may cause concerns among new parents and is a frequent reason for seeking help from their general practitioner (GP). The etiology of crying problems in infancy is not fully understood, but recent studies have found associations with maternal mental factors. It is well-established that postpartum depression is related to infant crying problems while the influence of maternal mental problems in pregnancy on infant crying is less investigated. We aimed to explore whether maternal depressive symptoms or maternal anxiety during pregnancy were related to crying problems by the newborn child.

Methods

In this prospective cohort study, 1290 pregnant women and their newborn children were followed throughout pregnancy until 8 weeks postpartum. Depressive symptoms and anxiety symptoms were assessed three times during pregnancy and again 8 weeks postpartum with the Major Depressive Inventory (MDI) and the Anxiety Symptoms Scale (ASS). Eight weeks postpartum the mothers were also asked whether their child cried in a way they found problematic. Multivariable regression was used to assess the association between depressive and anxiety symptoms during pregnancy and crying problems, and to adjust for potential confounders.

Results

We found statistically significant associations between high scores of depressive symptoms and anxiety symptoms in pregnancy and infant crying problems. Previously reported strong associations postpartum between depressive symptoms, anxiety symptoms and infant crying problems were also observed in the present data.

Conclusion

These results indicate that mental problems during pregnancy are associated with having a child with crying problems after birth. If more focus is given to maternal mental problems during pregnancy, the healthcare system might be able to detect and help these women, which would be beneficial for both mother and child.

The relative importance of work-related and non-work-related stressors and perceived social support on global perceived stress in a cross-sectional population-based sample

Background

High levels of perceived stress have a negative bearing on health and well-being, and stress is a major public health issue. According to the Stress Process Model, stressors are socially patterned and combine to produce strain. Despite this, most studies on stress have focused on work-related stressors leaving non-work determinants under-investigated. The aim of the present study was to determine the relative importance of work-related and non-work-related stressors and perceived social support for the overall perceived stress level.

Methods

Self-reported data were drawn from the 2017 population-based health survey “How are you?” conducted in the Central Denmark Region (N = 32,417). Data were linked with data drawn from national administrative registers. Work- and non-work-related stressors assessed included major life events, chronic stressors and daily hassles. Perceived social support was assessed using a single question. Overall perceived stress was assessed by the 10-item Perceived Stress Scale. We conducted dominance analyses based on a multiple linear regression model to determine the most important explanatory variables of overall perceived stress. Analyses were weighted and adjusted.

Results

Work- and non-work-related stressors along with perceived social support explained 42.5% of the total variance (R²) in overall perceived stress. The most important explanatory variables were disease, perceived social support and work situation. The stratified analyses produced slightly varying results (“dominance profiles”) of perceived stress between subgroups. Work situation was the most important explanatory variable in the employed group. However, adding non-work-related explanatory variables to the analysis tripled the explained variance.

Conclusions

The overall level of perceived stress can be statistically explained by a combination of work- and non-work-related stressors and perceived social support both at population level and in subgroups. The most important explanatory variables of overall perceived stress are disease, perceived social support and work situation. Results indicate that public health strategies aiming to reduce stress should take a comprehensive approach and address a variety of stressor domains rather than focus on a single domain.

Trial registration

The study was approved by the Danish Data Protection Agency (r. no. 2012-58-0006) and registered in the Central Denmark Region (r. no. 1-16-02-593-16).

Infantile Colic: New Insights into an Old Problem

Infant colic is a characteristic group of behaviors seen in young infants. The most prominent feature is prolonged crying. Additional characteristics, including clenching of the fists and flexion of the hips, have led to the suggestion that these behaviors are related to abdominal discomfort. In this article, we show emerging evidence to support the concept that infant colic could represent gut inflammation and microbial dysbiosis that impacts brain function and even brain development.

Systematic review on maternal depression versus anxiety in relation to excessive infant crying: it is all about the timing

Different types of studies suggest a link between maternal depression/anxiety and excessive infant crying (EC). However, comparability is hampered due to different designs, definitions and measurements. This systematic review investigates the specific role of maternal depression and anxiety considering them as preceding, concurrent and subsequent conditions of EC. A computerised literature search was conducted in January 2017 using Medline, PubMed, PsycINFO and Web of Science. After screening n = 399 records for inclusion/exclusion criteria, n = 33 records based on n = 30 projects were eligible for systematic qualitative data synthesis. All studies on maternal depression/anxiety and EC within the first 3 years of life were included. Included studies investigated predominantly maternal depression (25/30) and secondly maternal anxiety (17/30). Significant positive results were found in the majority of studies for maternal depression (21/25) as well as for maternal anxiety (12/17) in relation to EC. In-depth analyses further revealed that concurrent and subsequent maternal depression was robustly related with EC, whilst preceding maternal depression was not. In contrast, preceding and concurrent (but not subsequent) maternal anxiety was consistently related to subsequent EC. Maternal depression is more likely a correlate or even a consequence of EC, whereas anxiety is rather a temporally preceding condition and thus a potential risk factor or risk marker for both subsequent EC and associated maternal depression. Interventions for EC should address concurrent maternal depression, whilst preventive approaches might target preceding maternal anxiety as early as prior to or during pregnancy.

Early participation in a prenatal food supplementation program ameliorates the negative association of food insecurity with quality of maternal-infant interaction

Food insecurity is detrimental to child development, yet little is known about the combined influence of food insecurity and nutritional interventions on child development in low-income countries. We proposed that women assigned to an early invitation time to start a prenatal food supplementation program could reduce the negative influence of food insecurity on maternal-infant interaction. A cohort of 180 mother-infant dyads were studied (born between May and October 2003) from among 3267 in the randomized controlled trial Maternal Infant Nutritional Interventions Matlab, which was conducted in Matlab, Bangladesh. At 8 wk gestation, women were randomly assigned an invitation time to start receiving food supplements (2.5 MJ/d; 6 d/wk) either early (~9 wk gestation; early-invitation group) or at the usual start time (~20 wk gestation; usual-invitation group) for the government program. Maternal-infant interaction was observed in homes with the use of the Nursing Child Assessment Satellite Training Feeding Scale, and food-insecurity status was obtained from questionnaires completed when infants were 3.4-4.0 mo old. By using a general linear model for maternal-infant interaction, we found a significant interaction (P = 0.012) between invitation time to start a prenatal food supplementation program and food insecurity. Those in the usual-invitation group with higher food insecurity scores (i.e., more food insecure) had a lower quality of maternal-infant interaction, but this relationship was ameliorated among those in the early-invitation group. Food insecurity limits the ability of mothers and infants to interact well, but an early invitation time to start a prenatal food supplementation program can support mother-infant interaction among those who are food insecure.

Maternal psychosocial stress during pregnancy and placenta weight: evidence from a national cohort study

Background

To study in a large-scale cohort with prospective data the associations between psychosocial stress during pregnancy and placenta weight at birth. Animal data suggest that the placenta is involved in stress-related fetal programming.

Methodology/Principal Findings

We defined a priori two types of psychosocial stress during pregnancy, life stress (perceived burdens in major areas of life) and emotional symptoms (e.g. anxiety). We estimated the associations of maternal stress during pregnancy with placenta weight at birth, controlled for length of gestation, by predicting gestational age- and sex-specific z-scores of placenta weight through multiple regression analysis, adjusted for potential confounders (N = 78017 singleton pregnancies). Life stress (per increase in stress score by 1, range: 0–18) during pregnancy was associated with increased placenta weight at birth (z-score, reported in 10⁻³; B, 14.33; CI, 10.12–18.54). In contrast, emotional symptoms during pregnancy were not associated with placenta weight at birth.

Conclusions/Significance

Maternal life stress but not emotional symptoms during pregnancy was associated with increased placenta weight at birth; yet, the association-estimate was rather small. Our results may contribute to a better understanding of the role of the placenta in the regulation of intrauterine processes in response to maternal stress.

Predictive value of the cow's milk skin prick test in infantile colic

BACKGROUND AND OBJECTIVES

Infantile colic is a common problem among young infants. Cow's milk allergy has been suggested as one of the causes. We aimed to investigate the value of the cow's milk skin test for the diagnosis of cow's milk allergy in exclusively breast-fed infants with infantile colic.

METHODS

Exclusively breast-fed infants with infantile colic were enrolled in this study. On the first visit, the average hours of crying of the infant in a 24-h period were recorded and the cow's milk skin test was performed. If the infant had a positive skin test, elimination of cow's milk from the mothers' diet was advised. Infants with negative skin tests were divided into case and control groups. Cow's milk was eliminated from the diet of mothers in the case group. After 2 weeks, the number of hours of crying were recorded again. The reduction in the crying hours was compared between the two groups using the chi-square test.

RESULTS

Skin tests were positive in 3 of 114 cases (2.6%) of infantile colic. All three cases recovered completely following elimination of cow's milk from the mother's diet. Among the 111 patients with negative skin tests, 77 patients completed the study: 35 in the case group and 42 in the control group. The reduction in crying hours in infants in the case group was not significantly different from that in the control group.

CONCLUSION

Elimination of cow's milk from the mothers' diet is not beneficial for infants with a negative skin test. Infants with a positive skin test may benefit from this management.

Mothers' postpartum psychological adjustment and infantile colic

BACKGROUND

Infantile colic is a common problem of early infancy. There is limited data on the relation between postpartum maternal psychological problems and colic.

AIM

: To investigate whether infantile colic is associated with postpartum mood disorders or insecure adult attachment style of the mother.

METHODS

Seventy eight mothers and newborns were enrolled in this prospective, longitudinal study. Maternal depressive symptoms were screened with Edinburgh Postpartum Depression Score (EPDS) and maternal anxiety was assessed with State-Trait Anxiety Inventory (STAI). The Adult Attachment Scale was used to determine the attachment style of the mother. Infantile colic was defined according to Wessel criteria.

RESULTS

Infantile colic was present in 17 infants (21.7%); 12.9% of the mothers had an EPDS > or =13. The mean EPDS of the mothers whose infants had infantile colic (10.2+/-6.0) was significantly higher than that of the mothers of infants without colic (6.3+/-4.0). Among infants with infantile colic, 62.5% had mothers who had insecure attachment style, whereas only 31.1% of mothers had insecure attachment when the infant did not have infantile colic.

CONCLUSION

Postpartum maternal depressive symptoms and insecure attachment style are associated with infantile colic. Screening and early intervention of postpartum depression might promote the health of both the mother and infant.
