Parenting by mothers from marginalized communities and the role of socioeconomic disadvantage: insights from marginalized Roma communities in Slovakia.

Background: Roma living in marginalized communities often face poor living conditions and material deprivation, which may negatively impact parenting. Our aim is to compare the parenting behavior (support, harsh discipline, and stimulation) of mothers from marginalized Roma communities and the majority population in Slovakia. We also examine the role of socioeconomic disadvantage and related worries in the differences in parenting behavior between these groups. Methods: We obtained cross-sectional data from mothers of children aged 14-18 months using the first wave of the longitudinal RomaREACH study dataset. Two groups were included in the sample: 93 mothers from MRCs and 102 mothers from the majority. We performed multiple regression and mediation analyses to assess whether the educational level of mothers, the degree of poverty, and poverty-related feelings of stress and worries explain parenting behavior differences between the groups of mothers. Results: We found significant differences in parenting, especially in harsh disciplining and stimulation. These two domains were significantly associated with maternal education, degree of poverty, and poverty-related stress and worries. The degree of poverty partially mediated stimulation differences between the two groups of mothers. Conclusion: Parenting in MRCs seems harsher and less stimulative than parenting in the Slovak majority. These differences are associated with the socioeconomic disadvantage of mothers. The degree of poverty partially explains why parenting in MRCs is less stimulative. These results may inform intervention efforts aimed at disadvantaged families.

Stability of neurodevelopmental trajectories in moderately late and early preterm children born 15 years apart.

BACKGROUND: Neurodevelopmental trajectories of preterm children may have changed due to changes in care and in society. We aimed to compare neurodevelopmental trajectories in early and moderately late preterm children, measured using the Developmental (D)-score, in two cohorts born 15 years apart. METHODS: We included early preterm and moderately late preterm children from two Dutch cohorts (LOLLIPOP, 2002-2003 and ePREM, 2016-2017). ePREM counterparts were matched to LOLLIPOP participants by gestational age and sex. D-score trajectories were summarized by a multilevel model with random intercepts and random slopes, and multigroup analyses were used to test if the intercepts and slopes differed across cohorts. RESULTS: We included 1686 preterm children (1071 moderately late preterm, 615 early preterm) from LOLLIPOP, and matched these with 1686 ePREM counterparts. The neurodevelopmental trajectories of the two cohorts were mostly similar. For early preterm children, we found no statistically significant differences. For moderately late preterm children, both the intercept (43.0 vs. 42.3, p < 0.001) and slope (23.5 vs. 23.9, p = 0.002) showed some, but only clinically minor, differences. CONCLUSION: Developmental trajectories, measured using the D-score, in the first four years of life are comparable and stable across a period of 15 years for both early and moderately late preterm children. IMPACT: Neurodevelopmental trajectories are similar for early and moderately late preterm children born 15 years apart and thus seem quite stable in time. The validated Developmental score visualizes these trajectories based on developmental milestone attainment Because of its stability over time, the Developmental score trajectory may aid clinicians in neurodevelopmental assessment of preterm children as this simplifies monitoring and interpretation, similar to a growth chart.

Early stress during NICU stay and parent-reported health-related quality of life after extremely preterm birth: an exploratory study with possible targets for early intervention.

Introduction: The association between neonatal intensive care unit (NICU) related stress in preterm infants and their health-related quality of life (HRQoL) in the first year following preterm birth remains unexplored. Understanding this association is crucial for enhancing preventive and supportive measures for infants and parents within and beyond the NICU. Methods: From a single center observational cohort study, we included infants with gestational ages below 30 weeks and/or birth weights under 1,000 grams. HRQoL was quantified using the Infant Quality of Life Instrument (IQI) at 3-, 6-, 9- and 12-months corrected age, covering seven domains. NICU stress was quantified using the Neonatal Infant Stressor Scale (NISS) for the first week of life. We performed Spearman's correlation analyses to test this association. Results: Of the 45 included infants, the IQI was completed for 27 (60%) at 3, 15 (33%) at 6, 14 (31%) at 9 and 15 (33%) at 12 months. The HRQoL sum scores were related to neonatal stress at 9 and 12 months (ρ = 0.643 and 0.591, p = 0.013 and p = 0.019, respectively) but not at 3 and 6 months (ρ = -0.001 and -0.077 respectively, p > 0.05). Higher NICU stress tended to be associated with more respiratory and mood problems throughout the first year. Discussion: From a parental perspective on infant HRQoL, extremely preterm infants with higher stress exposure show more problems in the second half-year of life, mainly breathing and possibly mood-related problems. This knowledge may help improve our neonatal care, both during NICU stay and in follow-up clinics, by implementing targeted interventions.

Educational inequalities in major depressive disorder prevalence, timing and duration among adults over the life course: a microsimulation analysis based on the Lifelines Cohort Study.

BACKGROUND: Educational inequalities in major depressive disorder (MDD) pose a major challenge. Tackling this issue requires evidence on the long-term impact of intervening on modifiable factors, for example lifestyle and psychosocial factors. For this reason, we aimed to simulate the development of educational inequalities in MDD across the life course, and to estimate the potential impact of intervening on modifiable factors. METHODS: We used data from the prospective Dutch Lifelines Cohort Study to estimate the required input for a continuous-time microsimulation. The microsimulation allowed us to project the development of educational inequalities in MDD between ages 18 and 65, and to assess the potential benefit of intervening on quality of social contacts, health literacy and smoking. RESULTS: On average, an additional 19.1% of individuals with low education will ever experience MDD between ages 18 and 65 compared with those with high education. Additionally, individuals with low education generally will develop MDD 0.9 years earlier and spend 1.2 years more with MDD, than individuals with high education. Improving the quality of social contacts in individuals with low education produced the largest effect; it would reduce the inequalities in the prevalence, onset and duration of MDD by an average of 18.4%, 18.3% and 28.6%, respectively. CONCLUSIONS: Intervening on modifiable factors, particularly quality of social contacts, in individuals with low education could help reduce the estimated educational inequalities in MDD over the life course.

Neonatal stress exposure and DNA methylation of stress-related and neurodevelopmentally relevant genes: An exploratory study.

BACKGROUND: Stress exposure during Neonatal Intensive Care Unit (NICU) stay may have long-lasting effects on neurodevelopmental outcomes in extremely preterm infants. Altered DNA methylation of stress-related and neurodevelopmentally relevant genes may be an underlying mechanism. AIMS: This exploratory study aimed to investigate the association between neonatal stress exposure and DNA methylation in these genes at two different time points: early during the NICU stay (7-14 days after birth) and later, at discharge from the NICU. SUBJECTS: We included 45 extremely preterm infants in this prospective cohort study, gestational age 24-30 weeks. OUTCOME MEASURES: We collected fecal samples at days 7-14 (n = 44) and discharge (n = 28) and determined DNA methylation status in predefined regions of NR3C1, SLC6A4, HSD11B2, OPRM1, SLC7A5, SLC1A2, IGF2, NNAT, BDNF and GABRA6 using pyrosequencing. Because of low DNA concentrations in some fecal samples, we could do so in 25-50 % of collected samples. We prospectively quantified daily neonatal stress exposure using the Neonatal Infant Stressor Scale (NISS) and explored associations between cumulative NISS scores and average DNA methylation status. RESULTS: Rates of methylation of most genes were not statistically different between day 7-14 and discharge, except for OPRM1. We found moderately high and mostly negative correlation coefficients upon discharge with the cumulative NISS for the NR3C1, SLC6A4, SLC1A2, IGF2, BDNF and OPRM1 genes, albeit not statistically significant. CONCLUSIONS: Findings suggest that expression of stress-related and neurodevelopmentally relevant genes may be differently regulated following higher neonatal stress exposure. Larger studies should challenge the findings of this study and ideally test the effects on gene expression.

Educational inequalities in metabolic syndrome prevalence, timing, and duration amongst adults over the life course: a microsimulation analysis based on the lifelines cohort study.

BACKGROUND: Educational inequalities in metabolic syndrome (MetS) are a growing public health concern. Intervening on modifiable factors may help reduce these inequalities, but there is a need for evidence on the long-term impact of intervening on these factors. Thus, we simulate the development of educational inequalities in MetS across the life course and assess the impact of intervening on the modifiable factors that contribute to these inequalities. METHODS: We used data from the prospective multigenerational Dutch Lifelines Cohort Study to estimate the required input for a continuous-time microsimulation. The microsimulation projects the development of educational inequalities in MetS between ages 18 and 65, and assesses the potential benefit of intervening on smoking, alcohol use, diet quality, and health literacy. FINDINGS: The likelihood of ever experiencing MetS between ages 18 and 65 varies from 32.5% among high educated women to 71.5% among low educated men. On average, 27.6% more individuals with low education will ever experience MetS between ages 18 and 65 compared to those with high education. Additionally, individuals with low education generally will develop MetS 2.3 years earlier, and will spend an extra 2.6 years with MetS, compared to individuals with high education. Changes to smoking behaviours in individuals with low education produced the largest effect; it would reduce inequalities in prevalence, timing and duration by an average of 7.5%, 9.5%, and 6.9%, respectively. CONCLUSIONS: Interventions targeting the modifiable factors included in this study, especially smoking, could help reduce the estimated educational inequalities in MetS over the life course.

Impact of trajectories of maternal postpartum depression on infants' socioemotional development.

BACKGROUND: We assessed (a) the effects of postpartum depression (PPD) trajectories until 6 months postpartum on infants' socioemotional development (SED) at age 12 months, and (b) the mediating role of maternal self-efficacy (MSE), and the additional effect of postpartum anxiety at age 12 months. METHODS: We used data from POST-UP trial (n = 1843). PPD was assessed using the Edinburgh Postnatal Depression Scale (EPDS) at 1, 3, and 6 months. Infants' SED was assessed at 12 months using the Ages and Stages Questionnaire-Social-Emotional (ASQ-SE). Structural equations were applied to estimate the effect of PPD trajectories on infants' SED and mediation by MSE. The additional effects of postpartum anxiety were assessed with conditional regression. RESULTS: Higher levels of PPD over time were associated with a lower SED (coefficient for log-EPDS 3.5, 95% confidence interval 2.8; 4.2, e.g., an increase in the EPDS score from 9 to 13 worsens the ASQ-SE by 1.3 points). About half of this relationship was mediated by MSE. Postpartum anxiety had an independent adverse effect on SED. CONCLUSIONS: PPD and postpartum anxiety have a negative impact on infants' SED. MSE as a mediator may be a potential target for preventive interventions to alleviate the negative effects of maternal psychopathology on infants' SED. IMPACT: The trajectories of postpartum depression (PPD) from 1 month to 6 months were negatively related to infants' socioemotional development (SED) at age 12 months, underlining the importance of repeated assessment of PPD. Maternal self-efficacy (MSE) mediated the association between PPD and SED, implying MSE could be a potential target for preventive interventions. An additional independent negative effect of postpartum anxiety was identified, implying the assessment of postpartum anxiety also has a surplus value to identify mothers at risk.

Known groups validity of the SPARK36: To guide nurse-led consultations for the early detection of child developmental and parenting problems.

AIM: Early detection of child developmental and parenting problems is important for timely prevention. The SPARK36 (Structured Problem Analysis of Raising Kids aged 36 months) is a novel broad-scope structured interview guide aimed at assessing parenting concerns and needs for support for child developmental and parenting problems, using the parental and professional's (Youth Health Care nurses) perspective. The applicability of the SPARK36 in practice was already demonstrated. Our aim was to evaluate its known groups validity. DESING/METHODS: SPARK36 data were collected in a cross-sectional study in 2020-2021. The known groups validity was assessed by testing two hypotheses: the SPARK36 risk assessment shows a higher risk of parenting and child developmental problems in children (1) from parents with a lower socioeconomic status and (2) from families with ≥4 risk factors for child maltreatment. To test the hypotheses, Fisher's exact tests were applied. RESULTS: In total, 29 Youth Health Care nurses from four School Health Services performed SPARK36-led consultations with 599 parent-child pairs to assess the risk for child developmental and parenting problems. Both hypotheses were accepted at a significant p level. CONCLUSION: The results of the known groups validity support the hypothesis that the SPARK36 risk assessment for child developmental and parenting problems is carried out in a valid way. Future research is needed to assess other aspects of the validity and reliability of the SPARK36. IMPACT: This is a first step in validating the instrument for use during a nurse-led consultation with parents of 3-year-olds in Flemish School Health Services. Thereby, SPARK36 supports the nurses in accomplishing their assignment, making a risk assessment, and contributes to quality of care. PATIENT OR PUBLIC CONTRIBUTION: This study aimed to evaluate the known groups validity of the SPARK36. Therefore, it was not conducted using input from the public or the patient population.

Socioeconomic inequalities in paediatric metabolic syndrome: mediation by parental health literacy.

BACKGROUND: Parental health literacy may explain the relationship between parental socioeconomic status (SES) and paediatric metabolic syndrome (MetS). For this reason, we assessed to what extent parental health literacy mediates the relationships between parental SES and paediatric MetS. METHODS: We used data from the prospective multigenerational Dutch Lifelines Cohort Study. Our sample consisted of 6683 children with an average follow-up of 36.2 months (SD 9.3) and a mean baseline age of 12.8 years (SD 2.6). We used natural effects models to assess the natural direct, natural indirect and total effects of parental SES on MetS. RESULTS: On average, an additional 4 years of parental education, e.g. university instead of secondary school, would lead to continuous MetS (cMetS) scores that were 0.499 (95% confidence interval (CI): 0.364-0.635) units lower, which is a small effect (d: 0.18). If parental income and occupational level were 1 SD higher, on average cMetS scores were 0.136 (95% CI: 0.052-0.219) and 0.196 (95% CI: 0.108-0.284) units lower, respectively; these are both small effects (d: 0.05 and 0.07, respectively). Parental health literacy partially mediated these pathways; it accounted for 6.7% (education), 11.8% (income) and 8.3% (occupation) of the total effect of parental SES on paediatric MetS. CONCLUSIONS: Socioeconomic differences in paediatric MetS are relatively small, the largest being by parental education. Improving parental health literacy may reduce these inequalities. Further research is needed into the mediating role of parental health literacy on other socioeconomic health inequalities in children.

Piloting a complex intervention to promote a tobacco and alcohol-free pregnancy: the Smoke and Alcohol Free with EHealth and Rewards (SAFER) pregnancy study.

BACKGROUND: Tobacco smoking and alcohol consumption before and during pregnancy increase the risk of adverse health outcomes for mother and child. Interventions to address smoking and drinking before and during pregnancy have the potential to reduce early-life health inequalities. In the Smoke and Alcohol Free with EHealth and Rewards (SAFER) pilot study we aimed to evaluate the acceptability, feasibility and effectiveness of a complex intervention supporting women in smoking and alcohol cessation before and during pregnancy. METHODS: From February 2019 till March 2021, we piloted the SAFER pregnancy intervention among pregnant women and women planning pregnancy in South-West Netherlands in an uncontrolled before-after study. Participants were supported in smoking and alcohol cessation via up to six group sessions and an online platform. In addition, biochemically validated cessation was rewarded with incentives (i.e. shopping vouchers) amounting up to 185 euros. We aimed to include 66 women. The primary outcome was smoking and/or alcohol cessation at 34-38 weeks of gestation (if pregnant) or after six group sessions (if not pregnant). Quantitative data were analysed using descriptive statistics. Focus group interviews among those involved in the study were conducted at the end of the study to explore their experiences. Qualitative data was analysed using thematic analysis. RESULTS: Thirty-nine women who smoked were included; no women who consumed alcohol were referred to the study. Unemployment (51%), financial problems (36%) and a smoking partner (72%) were common. Thirteen women (33%) dropped out, often due to other problems impeding smoking cessation or 'being too busy' to participate in the group sessions. Eleven women (28%) had quit smoking at the study's endpoint. The personal and positive approach was highly valued and biochemical validation was felt to be helpful. CONCLUSION: The SAFER pregnancy intervention seems appropriate for women in need of extra support for smoking cessation before and during pregnancy. Its impact on alcohol cessation could not be studied due to recruitment issues. Recruitment and prevention of early dropout need attention in further development of this intervention. TRIAL REGISTRATION: Netherlands Trial Register: NL7493. Date registered: 04/02/2019.

Desirable but not feasible: Measures and interventions to promote early childhood health and development in marginalized Roma communities in Slovakia.

Roma are the largest and most disadvantaged ethnic minority in Europe often facing generational poverty, and limited access to education, employment, housing, and various types of services. Despite many international and national initiatives, children from marginalized Roma communities face multiple risks and are being disadvantaged as early as from conception onward. We, therefore, aimed to identify measures and/or interventions targeting equity in early childhood health and development in marginalized Roma communities which implementation is considered to be urgent but not feasible. We used a group concept mapping approach-a participatory mixed research method-and involved 40 experts and professionals from research, policy and practice. From 90 measures and interventions proposed to achieve early childhood equity for children from marginalized Roma communities, 23 measures were identified as urgent but not feasible. These concerned particularly measures and interventions targeting living conditions (including access to income, access to housing, and basic infrastructure for families) and public resources for instrumental support (covering mainly topics related to financial and institutional frameworks). Our results reflect the most pressing issues in the area of equality, inclusion and participation of Roma and expose barriers to implementation which are likely to arise from public and political discourses perpetrating a negative image of Roma, constructing them as less deserving. Measures to overcome persistent prejudices against Roma need to be implemented along with the measures targeting equity in early childhood health and development.

Increases in symptoms of depression and anxiety in adults during the initial phases of the COVID-19 pandemic are limited to those with less resources: Results from the Lifelines Cohort Study.

BACKGROUND: The COVID-19 pandemic may have a differential impact on mental health based on an individual's capital, i.e. resources available to maintain and enhance health. We assessed trajectories of depression and anxiety symptoms, and their association with different elements of capital. METHODS: Data on 65,854 individuals (mean baseline age = 50·4 (SD = 12·0) years) from the Lifelines COVID-19 cohort were used. Baseline mental health symptoms were on average measured 4.7 (SD = 1·1) years before the first COVID-19 measurement wave, and subsequent waves were (bi)weekly (March 30─August 05, 2020). Mental health symptom trajectories were estimated using a two-part Latent Class Growth Analysis. Class membership was predicted by economic (education, income, and occupation) and person capital (neuroticism, poor health condition, and obesity) FINDINGS: Most individuals were unlikely to report symptoms of depression (80·6%) or anxiety (75·9%), but stable-high classes were identified for both conditions (1·6% and 6·7%, respectively). The stable-high depression class saw the greatest increase in symptoms after COVID, and the stable-high anxiety class reported an increase in the probability of reporting symptoms after COVID. At the first COVID-measurement, the mean number of symptoms increased compared to baseline (depression:4·7 vs 4·1; anxiety:4·3 vs 4·2); the probability of reporting symptoms also increased (depression:0·96 vs 0·65; anxiety:0·92 vs 0·70). Membership in these classes was generally predicted by less capital, especially person capital; odds ratios for person capital ranged from 1·10-2·22 for depression and 1·08-1·51 for anxiety. INTERPRETATION: A minority of individuals, possessing less capital, reported an increase in symptoms of depression or anxiety after COVID. FUNDING: This research did not receive any specific grant from funding agencies in the public, commercial, or not-for-profit sectors.

Connecting Obstetric, Maternity, Pediatric and Preventive Child Health Care: A Comparative Prospective Study Protocol.

Collaboration between birth care and Preventive Child Health Care (PCHC) in the Netherlands is so far insufficient. The aim of the Connecting Obstetric; Maternity; Pediatric and PCHC (COMPLETE) study is to: (1) better understand the collaboration between birth care and PCHC and its underlying mechanisms (including barriers and facilitators); (2) investigate whether a new multidisciplinary strategy that is developed as part of the project will result in improved collaboration. To realize the first aim, a mixed-method study composed of a (focus group) interview study, a multiple case study and a survey study will be conducted. To realize the second aim, the new strategy will be piloted in two regions in an iterative process to evaluate and refine it, following the Participatory Action Research (PAR) approach. A prospective study will be conducted to compare outcomes related to child health, patient reported outcomes and experiences and quality of care between three different cohorts (i.e., those that were recruited before, during and after the implementation of the strategy). With our study we wish to contribute to a better understanding of collaboration in care and develop knowledge on how the integration of birth care and PCHC is envisioned by stakeholders, as well as how it can be translated into practice.

Pediatric patients' views regarding smoke-free hospital grounds compared to those of adults: A survey study.

INTRODUCTION: Children are important stakeholders in discussions about regulation of smoking and protection from secondhand smoke, but are rarely acknowledged as such. We explored the opinion of pediatric patients and other key stakeholders regarding the planned smoke-free zone around the Erasmus MC, a large university hospital in the Netherlands. METHODS: In 2019, we conducted a survey among pediatric patients and their parents, Erasmus MC employees, visitors, and adult patients, before implementation of the outdoor smoke-free zone, to assess their opinions on smoking and the planned smoke-free policy. Qualitative and quantitative data were collected and analyzed mostly using descriptive statistics and thematic analysis. RESULTS: In all, 91 parent-child dyads and 563 employees, visitors, patients and students filled in the questionnaires. Over 90% of children reported that they were regularly exposed to tobacco smoke, most often on the streets. Many underlined the exemplary role of healthcare providers, and 89% felt that nobody should be allowed to smoke near the hospital. Among parents, 89% were (very) positive towards the planned implementation of the smoke-free zone. In addition, 70% of adult patients, 81% of employees, 65% of visitors, 89% of students and 75% of 'others' were (very) positive about the new smoke-free policy. Smokers and former smokers generally were less positive about the policy. CONCLUSIONS: Children generally disapproved smoking around a hospital and felt that healthcare providers should be a good example concerning not smoking. The majority of adult patients, employees and visitors support a smoke-free zone surrounding the hospital, and virtually all pediatric patients and their parents do. Children should be acknowledged as important stakeholders in smoke-free policies and should be involved in planning and implementation.

How to make healthy early childhood development more likely in marginalized Roma communities: a concept mapping approach.

BACKGROUND: This study aims to assess which measures could improve the healthy early childhood development of children from marginalized Roma communities and to identify priority measures. METHODS: Concept mapping approach was used, using mixed methods. In total 54 professionals, including social workers, educators, health care providers, municipality representatives, and project managers participated in our study. RESULTS: Four distinct clusters of measures targeting living conditions, public resources, healthcare and community interventions, and 27 individual priority measures of highest urgency and feasibility were identified. The cluster 'Targeting living conditions', was rated as the most urgent but least feasible, whereas the cluster 'Targeting health care', was considered least urgent but most feasible. Among the 27 priority measures, 'Planning parenthood' and 'Scaling up existing projects' had the highest priority. CONCLUSION: Our results reflect the public and political discourse and indicate significant barriers to implementation. Reducing inequalities in early childhood needs to be addressed through coordinated efforts.

Criterion Validity and Applicability of Motor Screening Instruments in Children Aged 5-6 Years: A Systematic Review.

The detection of motor developmental problems, especially developmental coordination disorder, at age 5-6 contributes to early interventions. Here, we summarize evidence on (1) criterion validity of screening instruments for motor developmental problems at age 5-6, and (2) their applicability. We systematically searched seven databases for studies assessing criterion validity of these screening instruments using the M-ABC as reference standard. We applied COSMIN criteria for systematic reviews of screening instruments to describe the correlation between the tests and the M-ABC. We extracted information on correlation coefficients or area under the receiver operating curve, sensitivity and specificity, and applicability in practice. We included eleven studies, assessing eight instruments: three performance-based tests (MAND, MOT 4-6, BFMT) and five questionnaires (DCD-Q, PQ, ASQ-3, MOQ-T-FI, M-ABC-2-C). The quality of seven studies was fair, one was good, and three were excellent. Seven studies reported low correlation coefficients or AUC (<0.70), four did not report these. Sensitivities ranged from 21-87% and specificities from 50-96%, with the MOT4-6 having the highest sensitivity and specificity. The DCD-Q, PQ, ASQ-3, MOQ-T-FI, and M-ABC-2-C scored highest on applicability. In conclusion, none of the instruments were sufficiently valid for motor screening at age 5-6. More research is needed on screening instruments of motor delay at age 5-6.

An innovative postnatal risk assessment and corresponding care pathways in Preventive Child Healthcare.

AIMS: This study aims to evaluate the effectiveness of an innovative postnatal risk assessment (the postnatal Rotterdam Reproductive Risk Reduction checklist: R4U) and corresponding care pathways in Preventive Child Healthcare (PCHC), along with PCHC professional satisfaction. DESIGN: Four PCHC organizations located in three municipalities with a higher adverse perinatal outcome than the national average were selected for participation. The study concerns a historically controlled study design. METHODS: The study enrolled participants from September 2016 until December 2017. The historical cohort existed of children born in previous years from 2008 until 2016. The outcome measure was defined as catch-up growth: more than 0.67 standard deviation score weight for height increase in the first 6 months of life. PCHC professional opinion was assessed with a digital survey. RESULTS: After the inclusion period, 1,953 children were included in the intervention cohort and 7,436 children in the historical cohort. Catch-up growth was significantly less common in the intervention cohort; 14.9% versus 19.5% in the historical cohort (p < 0.001). A regression sensitivity analysis, using matching, showed an odds ratio of 0.957 (95% CI 0.938-0.976) for the intervention cohort. In the survey, 74 PCHC physicians and nurses participated; most of them were neutral concerning the benefits of the postnatal R4U. CONCLUSION: This study shows that the implementation of a novel postnatal risk assessment including in PCHC is feasible and effective. Final efforts to ensure a widespread implementation should be taken. IMPACT: PCHC offers a unique opportunity to recognize and address risk factors for growth and development in children and to implement care pathways. Effective and widely implemented risk assessments in antenatal and PCHC are scarce. To our knowledge, this kind of evidence-based postnatal risk assessment has not been implemented in PCHC before and seizes the opportunity to prevent catch-up growth and its long-term effects.

Adolescents' mental health problems increase after parental divorce, not before, and persist until adulthood: a longitudinal TRAILS study.

Parental divorce is one of the most stressful life events for youth and is often associated with (long-lasting) emotional and behavioral problems (EBP). However, not much is known about the timing of the emergence of these EBP in adolescents relative to the moment of parental divorce, and its longitudinal effects. We therefore assessed this timing of EBP in adolescents of divorce and its longitudinal effects. We used the first four waves of the TRacking Adolescent's Individual Lives Survey (TRAILS) cohort, which included 2230 10-12 years olds at baseline. EBP were measured through the Youth Self-Report (YSR), as internalizing and externalizing problems. We applied multilevel analysis to assess the effect of divorce on EBP. The levels of both internalizing and externalizing problems were significantly higher in the period after parental divorce (ß = 0.03, and 0.03, respectively; p < 0.05), but not in the period before divorce, with a persistent and increasing effect over the follow-up periods compared to adolescents not experiencing divorce. Adolescents tend to develop more EBP in the period after parental divorce, not before. These effects are long-lasting and underline the need for better care for children with divorcing parents.

Course of Stress during the Neonatal Intensive Care Unit Stay in Preterm Infants.

INTRODUCTION: Understanding the course of stress during the neonatal intensive care unit stay may provide targets for interventions. Our aim was to describe the course of stress in preterm infants during the first 28 days of life, the influence of gestational age, and associations with clinical characteristics. METHODS: In a single centre prospective cohort study, we included infants with a gestational age <30 weeks and/or birth weight <1,000 g. We measured stress over the first 28 days using the Neonatal Infant Stressor Scale (NISS). We plotted daily NISS total and subcategory scores by gestational age. The subcategories were (1) nursing, (2) skin-breaking, (3) monitoring and imaging, and (4) medical morbidity-related scores. We assessed associations of cumulative NISS scores over the first 7, 14, and 28 days with clinical characteristics using regression analyses. RESULTS: We included 45 infants, with a median gestational age of 27 weeks. The mean daily NISS score was 66.5 (SD 8.7), with highest scores in the first 7 days of life. Scores decreased the slowest for the lowest gestational ages, in particular for nursing scores, rather than skin-breaking, monitoring and imaging, and medical morbidity-related scores. Adjusted for gestational age, infants with lower Apgar scores, sepsis, intraventricular haemorrhages, and on mechanical ventilation had significantly higher cumulative NISS scores at 7, 14, and 28 days. CONCLUSION: NISS scores varied greatly within infants and over time, with the highest mean scores in the first week after birth. The course of declining NISS scores in the first 28 days depended on gestational age at birth.

Associations between Socio-Economic Status and Unfavorable Social Indicators of Child Wellbeing; a Neighbourhood Level Data Design.

BACKGROUND: Living in deprivation is related to ill health. Differences in health outcomes between neighbourhoods may be attributed to neighbourhood socio-economic status (SES). Additional to differences in health, neighbourhood differences in child wellbeing could also be attributed to neighbourhood SES. Therefore, we aimed to investigate the association between neighbourhood deprivation, and social indicators of child wellbeing. METHODS: Aggregated data from 3565 neighbourhoods in 390 municipalities in the Netherlands were eligible for analysis. Neighbourhood SES scores and neighbourhood data on social indicators of child wellbeing were used to perform repeated measurements, with one year measurement intervals, over a period of 11 years. Linear mixed models were used to estimate the associations between SES score and the proportion of unfavorable social indicators of child wellbeing. RESULTS: After adjustment for year, population size, and clustering within neighbourhoods and within a municipality, neighbourhood SES was inversely associated with the proportion of 'children living in families on welfare' (estimates with two cubic splines: -3.59 [CI: -3.99; -3.19], and -3.00 [CI: -3.33; -2.67]), 'delinquent youth' (estimate -0.26 [CI: -0.30; -0.23]) and 'unemployed youth' (estimates with four cubic splines: -0.41 [CI: -0.57; -0.25], -0.58 [CI: -0.73; -0.43], -1.35 [-1.70; -1.01], and -0.96 [1.24; -0.70]). CONCLUSIONS: In this study using repeated measurements, a lower neighbourhood SES was significantly associated with a higher prevalence of unfavorable social indicators of child wellbeing. This contributes to the body of evidence that neighbourhood SES is strongly related to child health and a child's ability to reach its full potential in later life. Future studies should consist of larger longitudinal datasets, potentially across countries, and should attempt to take the interpersonal variation into account with more individual-level data on SES and outcomes.
