Cognitive development in children of adolescent mothers: The impact of socioeconomic risk and maternal sensitivity

[Adolescent parenthood: how can caregivers provide support in a parent-baby day hospital?]

Adolescent parenthood is a risky situation for the mental health of young people and for the development of infants. Yet adherence to psychological care remains difficult at this stage of life, notably because of the insecurity of attachment bonds often present in these young people. The "Les Oursons" parent-baby day hospital is presented, and clinical cases involving adolescent parents are discussed. They illustrate the particular interest of a global approach to father, mother and baby, and underline the opportunities to anchor initial psychological care for each. Network and community care are also interesting avenues to explore.

Young mother risk-taking moderates doula home visiting impacts on parenting and toddler social-emotional development

This longitudinal randomized controlled trial examined the impact of a doula home visiting intervention for young, low-income mothers on parenting and toddler social-emotional development and tested whether intervention effects were moderated by maternal emotional and behavioral health characteristics. 156 mothers were offered home visits from a home visitor starting in mid-pregnancy through several years postpartum, with a community doula also working with the mother during pregnancy and after the birth. 156 received case management. Interviews, video recordings of mother-child interactions, and toddler assessments were conducted at 3 weeks, 3 months, 13 months, and 30 months of age. Intent-to-treat analyses conducted with the full sample showed some intervention effects. Moderation analyses, however, showed that most effects were concentrated among mothers engaged in high levels of risk-taking (delinquent behaviors, school suspensions, smoking, alcohol use, sexual risk-taking). Among higher risk-taking mothers, the intervention was related to less intrusiveness during early infancy, less psychological and physical aggression during toddlerhood, more sensitive parenting attitudes, and greater toddler social relatedness. Maternal depressive symptoms were only a moderator for toddler behavior problems. These findings suggest that doula home visiting may be a particularly effective model for enhancing sensitive, non-aggressive parenting among young mothers with a history of risk-taking behavior.

Positive Parenting and Sociodemographic Factors Related to the Development of Chilean Children Born to Adolescent Mothers

The lack of economic resources has a negative effect on the maternal role of younger mothers. In Chile, the majority of adolescent pregnancies occur in socially and economically vulnerable contexts. The current study aimed to examine the relationship between demographic variables within the family context and parenting behaviors among Chilean adolescent mothers (including affection, responsiveness, encouragement, and teaching). These factors were correlated with communication, problem-solving abilities, and personal-social development in typically developing infants. The study included a sample of 79 Chilean adolescent mother-child dyads with children aged 10 to 24 months. Communication, problem-solving, and personal-social development were assessed using the Ages and Stages Questionnaire-3, along with a demographic information questionnaire. The parenting behaviors mentioned above were observed using the Spanish version of Parenting Interactions with Children: Checklist of Observations Linked to Outcomes. The findings indicated that mothers in employment and those who had not dropped out of school had children with better problem-solving skills. Additionally, children residing with their fathers and female children performed better in communication, problem-solving, and personal-social development. Maternal responsiveness was associated with communication and problem-solving, while maternal encouragement was linked to improved problem-solving skills. Maternal teaching was connected to communication, problem-solving, and personal-social development. The study emphasized the significance of parenting and sociodemographic factors among adolescent mothers and their influence on their children's development.

Nurturing care among adolescent mothers

Many studies show the impact of adolescent mothers on child development. To prevent the impact of adolescent pregnancy, nurturing care is needed to support optimal children's development. This study aims to identify comprehensive nurturing care among adolescent mothers. This study used secondary data in the integration of the 2018 National Socioeconomic Survey and Basic Health Survey. To measure nurturing care, 5 components were used: health, adequate nutrition, security and safety, responsive caregiving, and opportunities for early learning with latent class analysis. The results of the analysis showed that 62% of adolescent mothers provided uncompleted nurturing care. About 21% of adolescent mothers need assistance in improving nurturing care related to adequate nutrition and learning opportunities, and 17% need assistance to improve health, nutrition, responsive caregiving, and opportunities for early learning. Adolescent mothers are in need of comprehensive nurturing care for their children. Practice is needed in order to enhance nurturing care initiatives, particularly for teenage mothers.

Four-year-old children's pretend play complexity during free play and story stem play and associations with maternal sensitivity

Theory and research have linked pretend play in early childhood with the development of language and theory of mind. In 102 mother-child dyads at 4.5 years, we examined whether (1) introducing a story stem (a play narrative with socioemotional dilemmas) in a mother-child play context increases pretend play complexity compared with mother-child free play; and (2) maternal sensitivity is associated with pretend play complexity. Further, we explored whether the story stem increased child pretend play complexity more in dyads with mothers with low sensitivity compared with highly sensitive mothers. Sensitivity was coded using Coding Interactive Behavior and pretend play complexity with a global, integrated measure of the developmental level and quantity of play. Using generalized estimating equations, we found that pretend play complexity was positively associated with introducing a story stem and maternal sensitivity. Mixed methods ancova showed no significant interaction between play situation and maternal sensitivity. The findings stress the importance of maternal sensitivity and participation for play and how introducing a story stem may help promote child pretend play complexity.

History of "Serve and Return" and a Synthesis of the Literature on its Impacts on Children's Health and Development

Parent/caregiver sensitivity and responsiveness are important for children's health and development. The "serve and return" metaphor was created to help providers and caregivers understand the importance of sensitive and responsive early caregiving. In this review, we explain the concept of "serve and return", outline historical and theoretical principles that culminated in this metaphor, highlight parent and child constructs associated with "serve and return" interactions, and synthesize literature on sensitive and responsive caregiving and children's health and developmental outcomes. Nurses and other healthcare professionals in public policy, clinical, community, education, and research roles need knowledge of "serve and return" interactions.

Non-Intrusive Maternal Style as a Mediator between Playfulness and Children’s Development for Low-Income Chilean Adolescent Mothers

The aim of this study was to describe the relationship between low-income Chilean adolescent maternal playfulness and mothers’ non-intrusiveness in their children’s development and to analyze whether a mother’s non-intrusiveness mediates the relationship between maternal playfulness and children’s development. The Parental Playfulness Scale and the Subscale of Intrusiveness from the Early Head Start Research and Evaluation Project were used to assess maternal playfulness and mothers’ non-intrusiveness respectively. Ages and Stages Questionnaire 3rd Edition (ASQ-3) was applied to measure the children’s communication, gross and fine motor skills, problem-solving and personal–social development. The sample consisted of 79 mother–child dyads with children aged 10–24 months (M = 15.5, SD = 4.2) and their mothers aged 15–21 years old (M = 19.1, SD = 1.7). A bivariate analysis showed that maternal playfulness was significantly associated with communication, fine motor, problem-solving and personal–social development. Moreover, higher levels of communication, fine motor skills and problem-solving development were observed in the children of less intrusive mothers. Maternal playfulness had a significant effect on children’s development of language, problem-solving and personal–social skills when their mothers showed less intrusiveness during interaction. These findings contribute to the understanding of the interaction between adolescent mothers and their children. Active play and less intrusiveness can enhance child development.

Caregiver sensitivity supported young children's vocabulary development during the Covid-19 UK lockdowns

Previous studies have shown that caregivers' sensitive, responsive interactions with young children can boost language development. We explored the association between caregivers' sensitivity and the vocabulary development of their 8-to-36-month-olds during COVID-19 when family routines were unexpectedly disrupted. Measuring caregivers' sensitivity from home interaction videos at three timepoints, we found that children who experienced more-sensitive concurrent interactions had higher receptive and expressive vocabularies (N=100). Children whose caregivers showed more-sensitive interactions at the beginning of the pandemic showed greater expressive vocabulary growth six (but not 12) months later (n=58). Significant associations with receptive vocabulary growth were not observed. Our findings highlight the importance of sensitivity at a time when other positive influences on language development were compromised.

Positive Parenting and Early Childhood Cognition: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

This review examines the effectiveness of positive parenting interventions aimed at improving sensitivity, responsiveness, and/or non-harsh discipline on children's early cognitive skills, in four meta-analyses addressing general mental abilities, language, executive functioning, and pre-academics. The objectives are to assess the magnitude of intervention effectiveness and identify moderators of effectiveness. We include randomized controlled trials of interventions targeting positive parenting to improve cognition in children < 6 years. Studies that include children with neurodevelopmental and/or hearing disorders were excluded. MEDLINE, PsycINFO, ERIC, and ProQuest Dissertations & Theses (October 2021) and citation chaining identified relevant records. Five reviewers completed screening/assessments, extraction, and risk of bias. Pooled analysis in Comprehensive Meta-Analysis (Version 3) used random effects modeling, with moderation via Q-statistics and meta-regression. Positive parenting interventions led to significant improvements in mental abilities (g = 0.46, N = 5746; k = 33) and language (g = 0.25, N = 6428; k = 30). Effect sizes were smaller and nonsignificant for executive functioning (g = 0.07, N = 3628; k = 14) and pre-academics (g = 0.16, N = 2365; k = 7). Robust moderators emerged for language and cognition. For cognition, studies with higher risk of bias scores yielded larger intervention effects. For language, studies with younger children had larger effect sizes. Studies mitigated selection and detection bias, though greater transparency of reporting is needed. Interventions that promote parental sensitivity, responsiveness, and non-harsh discipline improve early mental abilities and language. Studies examining executive functioning and pre-academics are needed to examine moderators of intervention effectiveness. Trial registration Systematic review PROSPERO registration. CRD42020222143.

Cognitive and Mental Health of Young Mothers' Offspring: A Meta-analysis

BACKGROUND AND OBJECTIVES

The nature and magnitude of the cognitive and mental health risks among the offspring of young mothers is not fully understood. Our objective is to examine the risk of mental disorders in these offspring.

METHODS

Five databases (Medline, Embase, Web of Science, PsycINFO, and CINAHL) were searched from their inceptions until February 2022. Studies were eligible if they assessed offspring of young mothers (&lt;21 years), contained a control group, and assessed any cognitive and/or mental health outcomes. Random-effects meta-analysis was used to generate standardized mean differences (SMDs) in infants (0-3 years), children (4-9), adolescents (10-19), and adults (20+). Methodological bias was assessed using the Newcastle-Ottawa Scale.

RESULTS

51 outcomes were meta-analyzed. Levels of cognitive and learning problems were higher among the infants (SMD = 0.30 [95% confidence interval 0.0-0.55]) and adolescents (SMD = 0.43 [0.24 to 0.62]) of young mothers. Adolescents had more symptoms of delinquency (SMD = 0.24 [0.12 to 0.36]). As adults, they are more often convicted of violent crimes (SMD = 0.36 [0.22 to 0.50]). Internalizing symptoms were higher in these offspring in childhood (SMD = 0.29 [0.14 to 0.45]) and adulthood (SMD = 0.35 [0.34 to 0.36]). This review uses unadjusted data and is thus unequipped to infer causality. Studies have high attrition and rely heavily on self-report.

CONCLUSIONS

Young mothers' offspring have more cognitive, externalizing, and internalizing problems across the lifespan than individuals born to mothers ≥21 years of age. They may benefit from early detection and support.

Investigating the impact of a home-centred cognitive development support programme on the cognitive development of infants aged between 18 and 24 months

BACKGROUND

The experiences acquired in the first years when development and learning are most rapid make up the basis for subsequent periods. The aim in this research to determine whether the 'Home-Centered Cognitive Development Support Program', delivered to socio-economically disadvantaged infants aged between 18 and 24 months, had an impact on the cognitive development of the infants.

METHODS

An experimental design with pre-test, post-test and retention test control group was used as methodology for the research. Thirty infants, 15 in the experiment group and 15 in the control group, were included in the study. The Cognitive Assessment Tool for Young Children - CAYC, which was adapted to Turkish, was used to measure the cognitive development of infants in the study. In line with the objective of the study, a cognitive development support programme was implemented for infants aged 18 to 24 months, 2 days a week during 12 weeks, through home visits. To assess the effectiveness of the programme, pre-test, post-test and retention test results were compared.

RESULTS

Based on the results of the study, the Home-Centered Cognitive Development Support Program revealed a significant difference in the cognitive development of infants in the experiment group. The post-test mean score for all infants in the experimental group was significantly higher compared with the pre-test score.

CONCLUSION

The outcomes related to the Home-Centered Cognitive Development Support Program, which was applied individually to infants aged between 18 and 24 months, were discussed in terms of the cognitive development of the infants.

Pregnancy complications, substance abuse, and prenatal care predict birthweight in adolescent mothers

BACKGROUND

Reduced birthweight is associated with adverse physical and mental health outcomes later in life. Children of adolescent mothers are at higher risk for reduced birthweight. The current study aimed to identify the key risk factors affecting birthweight in a well-characterized sample of adolescent mothers to inform preventive public health efforts.

METHODS

Sixty-four adolescent mothers (≤ 21 years of age) provided detailed data on pregnancy, birth and psychosocial risk. Separate regression analyses with (1) birthweight and (2) low birthweight (LBW) as outcomes, and pregnancy complications, prenatal care, maternal age, substance abuse during pregnancy, socioeconomic risk, stressful life events and the child's sex as independent variables were conducted. Exploratively, a receiver operating characteristic (ROC) analysis was performed to investigate the quality of the discriminatory power of the risk factors.

RESULTS

The following variables explained variance in birthweight significantly: prenatal care attendance (p = .006), pregnancy complications (p = .006), and maternal substance abuse during pregnancy (p = .044). Prenatal care attendance (p = .023) and complications during pregnancy (p = .027) were identified as significant contributors to LBW. Substance abuse (p = .013), pregnancy complications (p = .022), and prenatal care attendance (p = .044) showed reasonable accuracy in predicting low birthweight in the ROC analysis.

CONCLUSIONS

Among high-risk adolescent mothers, both biological factors, such as pregnancy complications, and behavioural factors amenable to intervention, such as substance abuse and insufficient prenatal care, seem to contribute to reduced birthweight in their children, a predisposing factor for poorer health outcomes later in life. More tailored intervention programmes targeting the specific needs of this high-risk group are needed.

A randomized controlled trial testing the efficacy of a Nurse Home Visiting Program for Pregnant Adolescents

To test the efficacy of a nurse home visiting program (HVP) on child development, maternal and environmental outcomes in the first years of life. We conducted a randomized controlled trial to test the efficacy of Primeiros Laços, a nurse HVP for adolescent mothers living in a poor urban area of São Paulo, Brazil. Eighty adolescent mothers were included and randomized to receive either Primeiros Laços (intervention group, n = 40) or healthcare as usual (control group, n = 40). Primeiros Laços is a home visiting intervention delivered by trained nurses that starts during the first 16 weeks of pregnancy and continues to the child's age of 24 months. Participants were assessed by blind interviewers at 8-16 weeks of pregnancy (baseline), 30 weeks of pregnancy, and 3, 6, 12, and 24 months of child's age. We assessed oscillatory power in the mid-range alpha frequency via electroencephalography when the children were aged 6 months. Child development was measured by the Bayley Scales of Infant Development Third Edition (BSID-III). Weight and length were measured by trained professionals and anthropometric indexes were calculated. The home environment and maternal interaction with the child was measured by the Home Observation and Measurement of the Environment. Generalized estimating equation models were used to examine intervention effects on the trajectories of outcomes. Standardized effect sizes (Cohen's d) were calculated using marginal means from endpoint assessments of all outcomes. The trial was registered at clinicaltrial.gov: NCT02807818. Our analyses showed significant positive effects of the intervention on child expressive language development (coefficient = 0.89, 95% CI [0.18, 1.61], p = 0.014), maternal emotional/verbal responsivity (coefficient = 0.97, 95% CI [0.37, 1.58], p = 0.002), and opportunities for variety in daily stimulation (coefficient = 0.37, 95% CI [0.09, 0.66], p = 0.009). Standardized effect sizes of the intervention were small to moderate. Primeiros Laços is a promising intervention to promote child development and to improve the home environment of low-income adolescent mothers. However, considering the limitations of our study, future studies should be conducted to assess Primeiros Laços potential to benefit this population.Clinical Trial Registration: The study was registered at clinicaltrial.gov (Registration date: 21/06/2016 and Registration number: NCT02807818).

Exploring the Perspectives of South African Parents and Primary Caregivers Living in Low-Income Communities on What Children Need to Thrive within the First 1000 Days of Life

The first 1000 days is recognised as a critical period for the development of children. What children need to thrive in this particular phase of development may be different from any other phase. In South Africa, parents’ perception of children’s needs within the first 1000 days of life could be considered as emerging. Therefore, this study aims to explore the perspectives of South African parents and primary caregivers on what children need to thrive within the first 1000 days. An exploratory qualitative study design was used to explore the parents’ understanding of what children need to thrive in the first 1000 days. A purposive sampling approach was employed to select parents and primary caregivers in low-income communities. In all, thirty respondents participated in the study. The data were analysed using thematic analysis. During the analysis, four themes emerged. The themes included (1) the importance of parenting, care and support; (2) children’s need for holistic development; (3) parental roles; and (4) sharing responsibilities. Parents and primary caregivers living in low-income communities understand what children need to thrive within the first thousand days of life. The study could assist policymakers and service providers to design appropriate interventions for parents within these communities.

Informative title: Effects of social support, parenting stress and self-efficacy on postpartum depression among adolescent mothers in Jordan

AIM AND OBJECTIVE

This study investigated the effects of social support, parenting stress and maternal self-efficacy on postpartum depression among adolescent mothers in Jordan.

BACKGROUND

Adolescent pregnancy may have serious health, social and economic consequences for young women, families and communities. In Jordan, the incidence of adolescent pregnancy has increased from 5% in 2012 to 15% in 2018. Little attention has been given to postpartum depression among adolescent mothers in Arab and Middle Eastern countries.

METHOD

In a cross-sectional design using convenience sampling, 200 women aged less than 20 years, six to eight weeks postpartum and who could speak and read Arabic were interviewed in a participating health clinic. The interview occurred before or after a woman's scheduled clinic appointment and included socio-demographic data, Edinburgh Postnatal Depression Scale (EPDS), Maternity Social Support Scale (MSSS), Parenting Stress Scale (PSS) and Perceived Self-efficacy Scale (PSES). Data collection took place between December of 2018 and April of 2019. Reporting followed the STROBE guidelines.

RESULTS

Results revealed that 28.5% of adolescent mothers had probable postpartum depression. Mothers who reported high social support, high parenting stress, low self-efficacy, financial stress and marital conflict had significantly higher EPDS scores than those who did not report these stressors.

CONCLUSION

Prevalence of postpartum depression reported in this study warrants immediate action on early assessment, detection and intervention. High levels of social support may feel overwhelming for young mothers and contribute to high parenting stress, low maternal self-efficacy and marital conflict.

RELEVANCE TO CLINICAL PRACTICE

Adolescent mothers are at increased risk of PPD compared to mothers over 20 years of age. Perceived quality rather than availability of social support needs to be considered. Young mothers require education and early intervention prevention strategies to better prepared them for motherhood and manage stressors associated with their changing social role.

Promoting mother-infant relationships and underlying neural correlates: Results from a randomized controlled trial of a home-visiting program for adolescent mothers in Brazil

Poverty and teenage pregnancy are common in low-and-middle-income countries and can impede the development of healthy parent-child relationships. This study aimed to test whether a home-visiting intervention could improve early attachment relationships between adolescent mothers and their infants living in poverty in Brazil. Analyses were conducted on secondary outcomes from a randomized controlled trial (NCT0280718) testing the efficacy of a home-visiting program, Primeiros Laços, on adolescent mothers' health and parenting skills and their infants' development. Pregnant youth were randomized to intervention (n = 40) or care-as-usual (CAU, n = 40) from the first trimester of pregnancy until infants were aged 24 months. Mother-infant attachment was coded during a mother-infant interaction when the infants were aged 12 months. Electrophysiological correlates of social processing (mean amplitude of the Nc component) were measured while infants viewed facial images of the mother and a stranger at age 6 months. Infants in the intervention group were more securely attached and more involved with their mothers than those receiving CAU at 12 months. Smaller Nc amplitudes to the mother's face at 6 months were associated with better social behavior at 12 months. Our findings indicate that the Primeiros Laços Program is effective in enhancing the development of mother-infant attachment.

Risks of Adverse Childhood Outcomes According to Prenatal Time of Exposure to Zika Virus: Assessment in a Cohort Exposed to Zika During an Outbreak in Colombia

Late gestational exposure to Zika increases the odds of delay in the Bayley-II mental developmental index (MDI) in children with normal baseline neurologic assessments; 9-fold when comparing third and first trimester exposure. Risk of MDI developmental delay increases by 8% for each week of gestational age at time of exposure.

Impact of Home Parenting Environment on Cognitive and Psychomotor Development in Children Under 5 Years Old: A Meta-Analysis

This study aims to evaluate the relationship between home parenting environment and the cognitive and psychomotor development in children under 5 years old by using meta-analysis. A systematic search of the Chinese and English databases including Pubmed, Embase, the Cochrane Library, CNKI, Weipu, Wanfang, and CBMdisc databases from January 1, 1990, to July 31, 2021, was performed. Articles concerning the relationship between home parenting environment and the cognitive and psychomotor development in children under 5 years old were included. Review Manager 5.4 was used for meta-analysis. Subgroup analysis in terms of age and region were performed. A total of 12 articles were included, including 11 in English and 1 in Chinese. Meta-analysis showed that there was significant relationship between home parenting environment and the cognitive and psychomotor development of children (r = 0.31; r = 0.21). Subgroup analysis showed that correlation between home parenting environment and the cognitive and psychomotor development of children was stronger in children over 18 months compared to those under 17 months [(r = 0.33, r = 0.21) vs. (r = 0.28, r = 0.17)]. The converted summary r value between home parenting environment and cognitive development in developing and developed countries was both 0.32. Conclusively, there is a positive correlation between the home parenting environment and the cognitive and psychomotor development of children under 5 years old. Improving the home parenting environment of children is beneficial to promote their early development.

[Differences in Use of Early Intervention by Adolescent Mother-Child Dyads Compared to Adult Mothers and their Children]

Adolescent mothers and their children represent a high-risk group for unfavorable developmental outcomes. There are early health and support services for this group. The aim of the current study was to investigate and compare the use of these interventions by adolescent mother-child dyads compared to adult mothers and their children. N=99 mothers (age of children: 5.3±1.0 months) were interviewed regarding early interventions, which were sorted into three groups ("interaction interventions", "child development" and "maternal support interventions") and pooled according to costs. Group differences in utilization and, exploratively, differences in allocation paths between adolescent and adult mothers were investigated. "Interaction interventions" were significantly more frequently used by adolescent mothers (U: 605.50, p<0.001). Interventions concerning "child development" (U: 633.50, p<0.001) and "maternal support" (U: 477.50, p<0.001) and interventions to be paid for (U: 582.00, p<0.001) by adult mothers. Social contacts (U: 817.00, p=0.003) and general practitioners (GP)/gynecologists (U: 879.00, p = 0.054) directed the adult mothers significantly more often to interventions, whereas adolescent mothers significantly more frequently were directed to other professional contacts (U: 877.50, p=0.01) and the youth welfare service (U: 962.50, p=0.021) as intermediaries. Early interventions for child and maternal health and interventions with costs were used significantly less frequently by adolescent mothers. Healthcare professionals such as GPs, gynecologists and pediatricians, should expand their counselling services on health interventions and support services in the high-risk group of adolescent mothers.

Early Childhood Antecedents of Dehumanization Perpetration in Adult Romantic Relationships

Data from the Minnesota Longitudinal Study of Risk and Adaptation (MLSRA) were utilized to provide the first investigation into the early childhood antecedents of dehumanization (i.e., treating another as less than human) in adult romantic relationships. Drawing on a sample of 109 MLSRA participants, multiple assessments of maternal care and empathy were collected during infancy and early childhood. In adulthood, MLSRA participants and their romantic partners engaged in video recorded conflict discussions in which dehumanization perpetration was coded. Maternal hostility was a significant and unique predictor of dehumanization perpetration. This longitudinal association remained even when controlling for the partner’s displays of dehumanization and several demographic covariates. This study provides the first evidence of early childhood antecedents of dehumanization and highlights how experiences during the first few years of life can have enduring downstream consequences for people’s romantic relationships 20–30 years later.

Associations between individual variations in visual attention at 9 months and behavioral competencies at 18 months in rural Malawi

Theoretical and empirical considerations suggest that individual differences in infant visual attention correlate with variations in cognitive skills later in childhood. Here we tested this hypothesis in infants from rural Malawi (n = 198-377, depending on analysis), who were assessed with eye tracking tests of visual orienting, anticipatory looks, and attention to faces at 9 months, and more conventional tests of cognitive control (A-not-B), motor, language, and socioemotional development at 18 months. The results showed no associations between measures of infant attention at 9 months and cognitive skills at 18 months, either in analyses linking infant visual orienting with broad cognitive outcomes or analyses linking specific constructs between the two time points (i.e., switching of anticipatory looks and manual reaching responses), as correlations varied between -0.08 and 0.14. Measures of physical growth, and family socioeconomic characteristics were also not correlated with cognitive outcomes at 18 months in the current sample (correlations between -0.10 and 0.19). The results do not support the use of the current tests of infant visual attention as a predictive tool for 18-month-old infants' cognitive skills in the Malawian setting. The results are discussed in light of the potential limitations of the employed infant tests as well as potentially unique characteristics of early cognitive development in low-resource settings.

The Role of Maternal Parenting for Children's Behavior Regulation in Environments of Risk

This study investigates the role of maternal parenting and subjective theories for associations between environmental risk and children's behavior regulation combining a qualitative and quantitative approach. Mothers of 113 primary school children (M = 10.06, SD = 0.86) in Germany completed questionnaires on parenting, environmental risk, and their child's behavior regulation. To test for associations, we applied hierarchical regression models. Further, we conducted nine focus groups in settings of high and low environmental risk and used thematic analysis. Maternal warmth showed positive associations with children's behavior regulation. Restrictive maternal control and children's behavior regulation were related negatively. The negative association between environmental risk and children's behavior regulation was partly explained by restrictive maternal control. When maternal warmth was added into the model on environmental risk, restrictive maternal control, and children's behavior regulation, both maternal parenting practices lost its significant associations with children's behavior regulation. Qualitative findings gave insights into parents' subjective theories, suggesting adverse peer effects as possible explanation for the relation between environmental risk and children's behavior regulation. The results are discussed in terms of their contribution to theoretical considerations on behavior regulation development in different environmental risk settings.

A mother-child intervention program for adolescent mothers: Results from a randomized controlled trial (the TeeMo study)

Children of adolescent mothers are a high-risk group for negative child development. Previous findings suggest that early interventions may enhance child development by improving mother-child interaction. The purpose of the current study was to evaluate a mother-child intervention (STEEP-b) program in high-risk adolescent mother-infant dyads (N = 56) within a randomized controlled trial (RCT). Mother-child interaction was assessed at baseline (T1), postintervention (T2), and follow-up (T3). The primary outcome was the change in maternal sensitivity and child responsiveness from T1 to T2 that was measured by blinded ratings of videotaped mother-child-interaction with the Emotional Availability Scales. A modified intention-to-treat analysis was performed to examine the data. No intervention effect was found for maternal sensitivity, 95% CI [-0.59-0.60], p = .99, and child responsiveness, 95% CI [-0.51-0.62], p = .84. Maternal sensitivity and child responsiveness did not change over time in both groups (all ps > .05). A statistically nonsignificant, but potentially clinically meaningful difference emerged between rates of serious adverse events, SC: 4 (14.8%), STEEP-b: 1 (3.4%), possibly driven by different intensity of surveillance of dyads in the treatment groups. The current findings question the effectiveness of STEEP-b for high-risk adolescent mothers and do not justify the broad implementation of this approach.

[The impact of adolecent motherhood on child development in preschool children- identification of maternal risk factors]

The impact of adolecent motherhood on child development in preschool children- identification of maternal risk factors Abstract. Objective: This longitudinal study aims to identify relevant risk factors in adolescent mothers which might impact their child's cognitive and speech development as well as behavior problems at preschool age. Based on earlier findings, maternal sensitivity (EA), socioeconomic status (SES) and psychological stress were identified as potentially influencing factors. Method: N = 31 adolescent and N = 47 adult mothers with their children aged 3;0 to 5;9 (M = 3;55) participated in this study. Child variables included cognitive development (WPPSI-III), language development (SSV), and behavioral problems (SDQ). Maternal factors were EA, SES, and mental health problems (BSI-18). Results: Children of adolescent mothers performed worse on cognitive and speech development and are described by their mothers as exhibiting more behavioral problems compared to children of adult mothers. Mediation analyses revealed that the effect of maternal age on children's cognitive development is occurs through reduced maternal sensitivity of adolescent mothers. Further, higher psychological stress of adolescent mothers mediated the effect of maternal age on children's behavior problems. Conclusion: Preschool children of adolescent mothers showed poorer developmental outcomes compared to children of adult mothers. This is partly explained by lower maternal sensitivity and higher rates of psychological stress among adolescent mothers.

Assessing the impact of a family nurse-led intervention on young mothers' references to internal states

A mother's propensity to refer to internal states during mother–child interactions is important for her child's developing social understanding. However, adolescent mothers are less likely to reference internal states when interacting with their children. We investigated whether young mothers’ references to internal states are promoted by the Family Nurse Partnership (FNP) intervention, an intensive home‐visiting programme designed to support adolescent mothers in England. We also investigated family, maternal, and child factors associated with young mothers’ references to inner states during interactions with their children. Adolescent mothers (n = 483, aged ≤ 19 years when recruited in pregnancy) and their children participated in an observational substudy of a randomized controlled trial investigating the impact of FNP compared to usual care. Mother–child dyads were video‐recorded during free play, and mothers’ speech was coded for use of internal state language (references to cognitions, desires, emotions, intentions, preferences, physiology, and perception). We found no differences in mothers’ use of internal state language between the FNP and usual care groups. A sample‐wide investigation identified that other features of mothers’ language and relationship status with the child's father were associated with internal state language use. Findings are discussed with reference to targeted interventions and implications for future research.

Effects of Maternal Psychopathology and Education Level on Neurocognitive Development in Infants of Adolescent Mothers Living in Poverty in Brazil

BACKGROUND

Adolescent motherhood remains common in developing countries and is associated with risk factors that adversely impact infant neurodevelopment, including poverty, low maternal education, and increased maternal psychopathology. Yet, no published work has assessed how these factors affect early brain development in developing countries.

METHODS

This pilot study examined effects of maternal psychopathology and education on early neurocognitive development in a sample of adolescent mothers (N = 50, final n = 31) and their infants living in poverty in São Paulo, Brazil. Maternal symptoms of anxiety, depression, and attention-deficit/hyperactivity disorder and education level were assessed during pregnancy. Infant neurocognitive development was assessed at 6 months of age, with oscillatory power and functional connectivity in the theta (4-6 Hz), alpha (6-9 Hz), and gamma (30-50 Hz) frequencies derived from resting-state electroencephalography; temperament (negative affect, attention, and regulation); and cognitive, language, and motor skills. Cluster-based permutation testing and graph-theoretical methods were used to identify alterations in oscillatory power and connectivity that were associated with maternal psychopathology and education. Correlations between power and connectivity alterations were examined in relation to infants' overt cognitive behavioral abilities.

RESULTS

Increased maternal anxiety and lower maternal education were associated with weaker oscillatory connectivity in alpha-range networks. Infants with the weakest connectivity in the alpha network associated with maternal anxiety also showed the lowest cognitive ability. Greater maternal anxiety and attention-deficit/hyperactivity disorder were associated with increased absolute and relative theta power.

CONCLUSIONS

Our findings highlight the importance of addressing maternal psychopathology and improving education in poor adolescent mothers to prevent negative effects on infant neurodevelopment.

[Mental health of teenage mothers: impact on the next generation]

BACKGROUND

Motherhood in adolescence is associated with risks for both the young mother and the children.

OBJECTIVE

Presentation of the current state of research on the mental health of adolescent mothers and its effects on the development of their children.

MATERIAL AND METHODS

Electronic database search in PubMed using various combined key terms such as "teenage pregnancy", "adolescent pregnancy", "teenage mother", "child development", "mother-child interaction". Review of the literature of the sources found and discussion of current publications and databases of public institutions.

RESULTS

In addition to psychosocial risks such as fewer education years due to family formation and lower incomes, young mothers also suffer more frequently from mental disorders, both before pregnancy and due to the additional burden of motherhood in their own developmental phase of youth. These can have unfavorable effects on the mother-child interaction and on the psychosocial and cognitive development of the children, thereby leading to the transgenerational transmission of risk factors.

CONCLUSION

In addition to primary prevention by avoiding teenage pregnancies, early identification of adolescent mothers and children at risk for early treatment and intervention is necessary.
