Sleep deprivation and recovery: Endurance racing as a novel model.

The aim of this study was to investigate sleep-wake behavior and gain insights into perceived impairment (sleep, fatigue, and cognitive function) of athletes competing in two international multi-day adventure races. Twenty-four athletes took part across two independent adventure races: Queensland, Australia and Alaska, USA. Individual sleep periods were determined via actigraphy, and racers self-reported their perceived sleep disturbances, sleep impairment, fatigue and cognitive function. Each of these indices was calculated for pre-, during- and post-race periods. Sleep was severely restricted during the race period compared to pre-race (Queensland, 7:46 [0:29] vs. 2:50 [1:01]; Alaska, 7:39 [0:58] vs. 2:45 [2:05]; mean [SD], hh:mm). As a result, there was a large cumulative sleep debt at race completion, which was not 'reversed' in the post-race period (up to 1 week). The deterioration in all four self-reported scales of perceived impairment during the race period was largely restored in the post-race period. This is the first study to document objective sleep-wake behaviors and subjective impairment of adventure racers, in the context of two geographically diverse, multi-day, international adventure races. Measures of sleep deprivation indicate that sleep debt was extreme and did not recover to pre-race levels within 1 week following each race. Despite this objective debt continuing, perceived impairment returned to pre-race levels quickly post-race. Therefore, further examination of actual and perceived sleep recovery is warranted. Adventure racing presents a unique scenario to examine sleep, performance and recovery.

Exploring the Relationship Between Age at Nap Cessation and Social-Emotional Functioning in Children.

OBJECTIVE: The objective of this study was to examine variations in age at nap cessation and identify whether there is an association with social-emotional functioning (SEF) as measured by internalizing/externalizing behavior, child temperament, and social skills in a sample of early childhood education and care-attending children. METHODS: The sample comprised 1117 children from the Australian Effectiveness Early Educational Experiences for Children longitudinal early childhood study. We used children's age at nap cessation as retrospectively recalled by caregivers in 2011 or 2013 when children were between ages 2 and 7 years. Each child's SEF was reported by a caregiver using the Strengths and Difficulties Questionnaire, the Short Temperament Scale for Children, and the Social Skills Inventory Scale. Associations between children's age of nap cessation and SEF were tested using linear regressions. RESULTS: The children's age at nap cessation ranged from 6 months to 6 years. For each additional year of napping, children's total , conduct , externalizing , and peer behavior problems decreased by 0.39 (95% confidence interval [CI], -0.70 to -0.09), 0.11 (95% CI, -0.21 to -0.01), 0.11 (95% CI, -0.51 to -0.06), and 0.11 (95% CI, -0.20 to -0.02) units on the Strengths and Difficulties Questionnaire scale, respectively. No further significant associations were found. CONCLUSION: This is the first study reporting the age range of nap cessation and its associations with social-emotional functioning. Our findings demonstrate earlier cessation ages in Australian children attending Early Childhood Education and Care programs than previously reported and a small association with externalizing and peer problems.

A Missed Opportunity? Meal Provision in Early Childhood Education and Care Services in the Context of Socioeconomic Disadvantage.

OBJECTIVES: Early childhood education and care (ECEC) services are attended by most children before school entry, reaching many living in circumstances of poverty and providing opportunity to support their nutrition. In this study, we examine the extent to which this opportunity is being met, comparing two common types of service provision: centre- versus family- provided food. METHODS: Intensive in-situ observations were undertaken across 10 ECEC services in highly disadvantaged Australian communities. All meals provided to children aged 3.5-5 years across an ECEC day (N = 48), of which 11% were experiencing severe food insecurity, were photographed and analysed to assess nutritional adequacy with reference to national dietary standards. RESULTS: Meals provided did not meet national dietary recommendations for quality or quantity. Nutrition was least adequate in services with policies of family-provided food. These services were also those that served families experiencing the highest levels of severe food insecurity (29%). CONCLUSIONS: In the absence of policies for the provision of food in ECEC, services are not realising their potential to support child nutrition in the context of poverty presenting increased risk to lifetime trajectories of health and wellbeing. System level policy interventions are required to facilitate equitable access to nutritious food and attendant life chances.

Siblings' experiences of sleep disruption in families with a child with Down syndrome.

OBJECTIVE: Adverse effects of sleep disruption are identified in parents who live with a child with Down Syndrome (DS), yet there is no research on siblings' experiences. This study addresses this knowledge gap. DESIGN: A qualitative research study using semi-structured interviews to understand the experiences of siblings of a child with DS and sleep difficulties from the perspectives of parents and siblings. PARTICIPANTS: Eleven siblings aged 5-15 years old, and 11 parents, from 8 families with a child with DS in Australia. METHODS: Semi-structured sibling interviews explored what it was like to have a sibling with DS and sleep difficulties; the participant's own sleep; how their sleep affected how they felt during the day; how sleep impacted their family; and advice that they would give to other siblings. Parent interviews included similar topics; here we report on excerpts in which parents reference siblings. Interviews were audio recorded, transcribed verbatim, and analyzed using a reflexive thematic analysis. RESULTS: Siblings and parents acknowledge sleep disruption for siblings; yet sleep disruption is normalized, viewed with acceptance and inevitability. Siblings report adverse effects from sleep disruption, view sleep in a relational way, and cope with sleep disruption. Parents can underestimate siblings' sleep disruption and are uncertain whether siblings' symptoms result from sleep disruption or other causes. CONCLUSIONS: Siblings of a child with DS experience sleep disruption and may be at risk of developing long-term health problems without focused support.

Adverse childhood experiences, the risk of pregnancy complications and adverse pregnancy outcomes: a systematic review and meta-analysis.

BACKGROUND: Adverse childhood experiences (ACEs) have a profound negative impact on health. However, the strength of the association between ACEs and pregnancy complications and adverse pregnancy outcomes is not well quantified or understood. OBJECTIVE: To conduct a systematic review and meta-analysis of the association between ACEs and risk of pregnancy complications and adverse pregnancy outcomes. SEARCH STRATEGY: A comprehensive search was conducted using PubMed, Embase, CINAHL, PsycINFO, ClinicalTrials.gov and Google scholar up to July 2022. DATA COLLECTION AND ANALYSIS: Two reviewers independently conducted the screening and quality appraisal using a validated tool. Meta-analysis using the quality-effects model on the reported odds ratio (OR) was conducted. Heterogeneity and inconsistency were examined using the I2 statistics. RESULTS: 32 studies from 1508 met a priori inclusion criteria for systematic review, with 21 included in the meta-analysis. Pooled analyses showed that exposure to ACEs increased the risk of pregnancy complications (OR 1.37, 95% CI 1.20 to 1.57) and adverse pregnancy outcomes (OR 1.31, 95% CI 1.17 to 1.47). In sub-group analysis, maternal ACEs were associated with gestational diabetes mellitus (OR 1.39, 95% CI 1.11 to 1.74), antenatal depression (OR 1.59, 95% CI 1.15 to 2.20), low offspring birth weight (OR 1.27, 95% CI 1.02 to 1.47), and preterm delivery (OR 1.41, 95% CI 1.16 to 1.71). CONCLUSION: The results suggest that exposure to ACEs increases the risk of pregnancy complications and adverse pregnancy outcomes. Preventive strategies, screening and trauma-informed care need to be examined to improve maternal and child health.

Factor structure of the Edinburgh Postnatal Depression Scale in a large population-based sample of fathers.

BACKGROUND: Paternal perinatal distress is receiving increasing attention. The Edinburgh Postnatal Depression Scale (EPDS) is the predominant screening tool for paternal perinatal distress. Research using the large Avon Longitudinal Study of Parents and Children (ALSPAC) cohort demonstrated that a three-factor EPDS structure is appropriate among mothers, with anhedonia, anxiety and depression factors emerging consistently across perinatal timepoints. METHOD: We employed confirmatory factor (CFA; n = 6170 to 9848) analysis to determine if this structure was appropriate for ALSPAC fathers, and the extent of invariance between mother and father groups. RESULTS: At 18-weeks gestation, and 8-weeks, 8-months and 21-months postpartum, the three-factor model had consistently superior fit to other proposed models. Consistent with interpretation of a total distress score, factors were highly correlated. The model exhibited configural invariance in both the first (8-months) and second (21-months) post-partum years. Metric and scalar invariance were not supported, however, non-invariance was largely attributable to item 9 canvassing "crying". LIMITATIONS: While the study employs a large cohort, the data collection in 1991 to 1992 in the United Kingdom may not account for the diverse gender roles, family structures and societal changes seen since that time. CONCLUSIONS: Interpretation of the EPDS as representing perinatal distress, reflecting anhedonia, anxiety and depression aspects, is appropriate for mothers and fathers. The experience of distress has nuanced gender-based differences. Implications for EPDS interpretation and cut-off scores among fathers are discussed.

Mealtimes in the context of poverty: Comparison of ECEC services providing food and those requiring food provided from home.

BACKGROUND: In developed economies, most children attend Early Childhood Education and Care (ECEC) services before school entry, many from early life and across long days. For this reason, ECEC services present significant potential to provide food environments that positively influence eating behaviours and food preferences with attendant effect on life course trajectories of health and wellbeing. Yet there is evidence that feeding practices that limit optimal ongoing nutrition, such as pressure and restriction, are amplified in ECEC services serving disadvantaged communities. We sought to identify underlying explanatory mechanisms through observation of children's feeding experiences and educator explanations comparing, family-provided and service-provided meals. METHOD: This study used qualitative analyses of educator interviews and observation records from 55 mealtimes in 10 ECEC services: 5 providing food and 5 requiring family food provision. RESULTS: High levels of concern drove educator's controlling feeding practices at mealtimes but presented differently across meal provision modes. In centres that provided food, educators' concern focused on food variety, manifesting in pressure to 'try' foods. In centres requiring family-provided food, concern focused on nutrition quantity and quality and manifested as control of order of food consumption and pacing of intake to ensure food lasted across the day. Interview data suggested that conflict aversion limited optimal nutrition. In centres providing food, this was seen in menus that prioritized child food preferences. In centres requiring family meal provision, conflict aversion was seen as reticence to discuss lunchbox contents with families. CONCLUSION: The findings direct attention to public health intervention. Currently, ECEC face significant barriers to realizing their potential to support child nutrition and establish positive life course trajectories of nutrition. To do so requires targeted supports that enable sufficient supply and quality of food in the context of poverty.

Communicating the complex lives of families that include a child with Down syndrome.

Families of children with Down syndrome experience complex lives and needs, yet the few existing studies on these families are written in conventional academic prose that is not optimal for knowledge translation beyond academia, particularly for busy healthcare professionals. In this paper, we Depart Radically in Academic Writing (DRAW) (Mackinlay, 2022) and present data poetry and two case studies that draw upon semi-structured interviews with mothers, fathers, and siblings, who were interviewed separately about their experiences of having a child/sibling with Down syndrome. We introduce our interdisciplinary team that includes academics and clinicians to contextualise our focus on research translation. We demonstrate that writing with creative criticality (i.e. 'DRAWing') contributes an embodied and affective understanding of research participants' stories, which is largely lacking in the academic literature on families of children with Down syndrome and the sociology of health and illness field more broadly. Moreover, DRAWing can impact audiences emotionally as well as intellectually (Richardson, 2003, p. 924), which has important knowledge translation implications for both healthcare professionals and these families. DRAWing can capture healthcare professionals' attention, prompting them to critically reflect on their practices and opportunities for improving care and treatment for these families.

Meal provision in early childhood education and care programs: Association with geographic disadvantage, social disadvantage, cost, and market competition in an Australian population.

BACKGROUND: Across developed economies, most children attend early childhood education and care (ECEC) programs attending up to 10,000 h prior to school. These programs present significant opportunity for public health nutrition interventions through provision of healthy food. We sought to identify whether this opportunity is being taken through analysis of population data from Queensland, Australia. Specifically, we asked if meal provision occurs in locations where risk of food insecurity is high and how economic functioning of ECEC services is associated with meal provision. METHODS: Of ECEC services in Queensland, (N = 1623) administrative data on meal provision (2020) was available for 947 ECEC services (58.4% of cohort). We assessed the association of meal provision in these services with area indices of social disadvantage (geographic location, social disadvantage, proportion of child developmental vulnerability) and ECEC service economic functioning (fee structure, market competition). FINDINGS: ECEC services in remote and rural communities were less likely to provide meals. A similar but weaker trend was evident in socio-economically disadvantaged metropolitan communities. In these locations market competition increased likelihood of meal provision but without fee increase. INTERPRETATION: The competitive market works contrary to the potential for ECEC services to support child nutrition and promote public health. Children living in disadvantaged communities, where food insecurity is inevitably higher, are less likely to have meals provided by their ECEC service. Market competition increases the likelihood of meal provision, yet in disadvantaged communities, parents' ability to pay constrains fees that can be charged raising concern about food quality and effects on quality of provision more broadly. Systemic public supports to enable high quality food provision without compromising other aspects of quality, particularly in the most disadvantaged communities, should be a public health priority.

Emotional quality of early education programs improves language learning: A within-child across context design.

Observational studies comparing child outcomes in early care and education classrooms of differing quality are often confounded by between-child differences. A within-child design, tracking children across contexts, can identify the effects of quality with less confounding. An analysis of Australian children (N = 1128, mean age 5 years, 48% female, 2.9% Indigenous, ethnicity data unavailable) tracked across pre-K, K, and year 1 (2010-2012) was conducted to assess how changes in observed quality (Classroom Assessment Scoring System) were associated with changes in cognitive development (Woodcock-Johnson III). Thresholds of quality were also investigated. Increases in Emotional Support were associated with improved language development (ß = 0.54, 95% CI [0.1-0.99], approximating 2.6 weeks development). Results highlight that emotional quality is an integral and potent component of early learning.

Investigating endocrine-disrupting properties of chemicals in fish and amphibians: Opportunities to apply the 3Rs.

Many regulations are beginning to explicitly require investigation of a chemical's endocrine-disrupting properties as a part of the safety assessment process for substances already on or about to be placed on the market. Different jurisdictions are applying distinct approaches. However, all share a common theme requiring testing for endocrine activity and adverse effects, typically involving in vitro and in vivo assays on selected endocrine pathways. For ecotoxicological evaluation, in vivo assays can be performed across various animal species, including mammals, amphibians, and fish. Results indicating activity (i.e., that a test substance may interact with the endocrine system) from in vivo screens usually trigger further higher-tier in vivo assays. Higher-tier assays provide data on adverse effects on relevant endpoints over more extensive parts of the organism's life cycle. Both in vivo screening and higher-tier assays are animal- and resource-intensive and can be technically challenging to conduct. Testing large numbers of chemicals will inevitably result in the use of large numbers of animals, contradicting stipulations set out within many regulatory frameworks that animal studies be conducted as a last resort. Improved strategies are urgently required. In February 2020, the UK's National Centre for the 3Rs and the Health and Environmental Sciences Institute hosted a workshop ("Investigating Endocrine Disrupting Properties in Fish and Amphibians: Opportunities to Apply the 3Rs"). Over 50 delegates attended from North America and Europe, across academia, laboratories, and consultancies, regulatory agencies, and industry. Challenges and opportunities in applying refinement and reduction approaches within the current animal test guidelines were discussed, and utilization of replacement and/or new approach methodologies, including in silico, in vitro, and embryo models, was explored. Efforts and activities needed to enable application of 3Rs approaches in practice were also identified.

Associations between food provision and feeding practices in socially disadvantaged childcare centres.

Preschool children consume a large proportion of their daily food intake in their childcare settings. These settings, therefore, provide important opportunities for children to experience food socialisation, and related positive nutrition. Yet, the extent to which these opportunities are taken, particularly in socioeconomically disadvantaged areas where risk of poor nutrition is high, is not well documented. This study focused on 10 childcare centres in socially disadvantaged locations and examined daily feeding practices via direct in-situ observation (n = 189 children observed). Centres were randomly selected based on type of food provision: centre-provided (n = 5 centres) or family-provided (n = 5 centres). Analyses showed that where food was family-provided, educators were significantly more likely to use controlling feeding practices, including pressuring children to eat, restricting food choices and rushing children into finishing meals. These practices were particularly evident during mid-morning meals, where pressuring children to eat healthy foods first, was more often observed. Further research and interventions that target feeding practices in childcare are indicated and should consider how source of food provision impacts upon these practices.

Children's sleep and fathers' health and wellbeing: A systematic review.

Night-waking is typical across infancy and early childhood, inevitably disrupting family sleep. For some children, sleep problems develop and endure throughout childhood. This systematic review focused on fathers, and synthesised the evidence pertaining to the effects of children's sleep (from birth to 12 years) on fathers' health and wellbeing. A total of 29 studies were included. Key outcomes reported for fathers were: sleep and fatigue; mental and general health; and family functioning. An association between child sleep and father's sleep was observed when child's sleep was measured via actigraphy or paternal report, but not when measured via maternal report, suggesting that mothers may not always be aware of disruptions that awaken fathers. Findings showed poorer child sleep was associated with poorer general health and wellbeing among fathers, however, associations of poor child sleep with depression were fewer, and less frequent than those reported for mothers in the same households. Poor child sleep was negatively associated with the quality of family relationships, both within the couple and between parent and child. Future studies seeking to understand the interplay of child sleep and family wellbeing should apply objective measurement of sleep and integrate formal measures of family dynamics into the study design.

Perinatal depression screening in Australia: A position paper.

Perinatal depression can have enduring adverse effects on women and their children and families, incurring substantial ongoing economic and personal costs. A significant proportion of the cost of perinatal depression relates to adverse impacts on the child, most likely mediated through impairment to the mother-infant relationship. In recognition of this problem, Australia has invested in routine perinatal depression screening. Our previous research produced convergent findings suggesting that expected benefits for children have not yet been realised through perinatal depression screening. We question the potential of including a measure of personality in current perinatal depression screening for identifying maternal mental health problems and suboptimal mother-infant relationships. This paper reviews our previous research findings within the broader context of perinatal depression screening. We propose a position, that perinatal depression screening in Australia should be redesigned to more precisely detect vulnerable mother-infant relationships, parenting, maternal mental health, and infant psychosocial and psychological development. Practice change to appropriately target antenatal interventions may more efficiently improve both maternal and child outcomes, thereby contributing to greater efficiency and cost savings for the health system.

Comparison of Early Feeding Practices in Mother-Father Dyads and Possible Generalization of an Efficacious Maternal Intervention to Fathers' Feeding Practices: A Secondary Analysis.

To compare feeding practices within mother-father dyads and explore whether outcomes of an efficacious intervention for mothers generalised to fathers' feeding practices. The NOURISH RCT evaluated an early feeding intervention that promoted positive feeding practices to support development of healthy eating habits and growth. The intervention was delivered to first-time mothers via 2 × 12 week modules commencing when children were 4 and 14 months. Mothers self-reported feeding practice outcomes at child age 2 years using validated scales (1 = low to 5 = high) from the Child Feeding Questionnaire (CFQ). Nine months later, an independent cross-sectional descriptive study to investigate fathers' feeding practices was initiated. Fathers were recruited by contacting (via letter) mothers participating in two pre-existing studies, including the NOURISH trial. Fathers completed a feeding practices questionnaire, similar to that used for NOURISH outcome assessments. Seventy-five fathers recruited via the NOURISH cohort (21% response) returned questionnaires. Response data from this subset of fathers were then linked to the corresponding NOURISH maternal data. Complete data were available from 70 dyads. Compared with mothers, fathers self-reported higher concern about child overweight (2.2 vs. 1.3), restriction (3.6 vs. 2.9) and pressure (2.6 vs. 2.1), all p < 0.001. Fathers whose partners were allocated to the intervention group used less pressure (mean difference 0.46, p = 0.045) and were more willing to let the child decide how much to eat (-0.51, p = 0.032). Fathers' higher concern about child weight and more frequent use of non-responsive feeding practices, when compared with mothers, identify them as potentially potent contributors to child feeding. This preliminary evidence for modest generalisation of an efficacious maternal intervention to apparent effects on some paternal feeding practices speaks to the importance and promise of including fathers in early feeding interventions.

What children bring to the table: The association of temperament and child fussy eating with maternal and paternal mealtime structure.

Fussy eating is a nuanced, mealtime-specific behaviour associated with difficult temperament but has been rarely examined within the context of mealtime structure. The aim of this study was to a) examine associations between child temperament, and mothers' and fathers' structure-related feeding practices and b) explore whether these associations were mediated by child fussy eating. Cohabiting mother-father pairs (N = 205) of children aged between 2- to 5-years residing in a socioeconomically disadvantaged Australian city completed self-reported, validated measures of child temperament, food fussiness and structure-related feeding practices (structured meal timing, structured meal setting and family meal setting). Child temperament was associated with maternal and paternal structure-related feeding practices, such that more difficult temperament was associated with less mealtime structure. Mothers' perception of child food fussiness mediated the relationship between difficult temperament and increased provision of alternative meals to the child from the rest of the family. Additionally, mothers' and fathers' perception of child food fussiness mediated the relationship between difficult child temperament and lower frequency of sitting at a table together for family meals. Therefore, perceptions of child food fussiness may explain why mothers and fathers use less structure at mealtimes with children who have more difficult temperaments. These results suggests that similar intervention approaches can be used for both mothers and fathers from socioeconomically disadvantaged families to target fussy eating and structure the mealtime environment. Promoting mealtime structure to facilitate parents' appropriate responses to food refusal or difficult behaviour at mealtimes is indicated.

Supporting, failing to support and undermining breastfeeding self-efficacy: Analysis of helpline calls.

Although a complexity of factors explain early cessation of breastfeeding, the encounter of a problem is often a critical point in this decision. For this reason, breastfeeding self-efficacy, a mother's evaluations of her ability to successfully overcome challenges, is an effective target in interventions to sustain breastfeeding. This study examined factors affecting the success of one such intervention, reactive telephone support. Across a 4-week period, recordings of all calls to a nurse-staffed parent helpline in Queensland, Australia were made. Of these calls, 60 were from mothers encountering a breastfeeding problem. Using a standard protocol, each call was scored for trajectories of mother's breastfeeding self-efficacy from opening to close of call. Calls showing an upward trajectory were defined as supporting (53%), those with no change were defined as ineffective (25%), and those with downward trajectory as undermining (22%). Using trajectory scores, case exemplars were purposively selected for detailed analysis of interactional sequences to identify strategies that distinguished outcome. The supportive call was distinguished by information sharing, mutual trust and respectful relationships, and personalized affirmation and advice. The ineffective call focused on technical aspects of breastfeeding, whereas the undermining call made moral judgements of mother's behaviour. The findings identify interactional quality of telephone support, not simply provision, as the key success factor in reactive telephone support. The findings also present interactional quality as a potential explanation for inconsistent outcomes in evaluation of reactive telehealth interventions to support breastfeeding.

Associations between prenatal maternal mental health indices and mother-infant relationship quality 6 to 18 months' postpartum: A systematic review.

Maternal mental disorders can significantly impact on children's psychosocial and psychological development, incurring substantial ongoing economic and personal costs. A key mediating mechanism is mother-infant relationship quality (MIRQ). Research studies and perinatal mental health screening initiatives have predominantly focused on depressive symptoms and perinatal depression as predictors of MIRQ. While maternal depression is associated with suboptimal MIRQ, the findings have not been consistent. Personality characteristics are associated with parenting and proneness to depression, presenting a potential addition to prenatal mental health assessment. We conducted a systematic review of studies that have examined the link between prenatal depressive symptoms and/or personality characteristics with postnatal MIRQ. Our findings suggest that both maternal personality traits and depressive symptoms measured in early pregnancy are associated with postnatal MIRQ. A measure of personality characteristics may enhance prenatal mental health assessment, affording opportunities for targeted intervention commencing in pregnancy to improve MIRQ, parenting, maternal mental health outcomes, and infant psychosocial and psychological development, and thereby contributing to the reduction of human and economic cost burdens.

Los trastornos mentales maternos pueden impactar significativamente el desarrollo sicosocial y sicológico de los niños lo cual conlleva considerables continuos costos económicos y personales. Un mecanismo mediador clave es la calidad de la relación madre-infante (MIRQ). Los estudios investigativos y las iniciativas de exámenes de salud mental perinatales predominantemente se enfocan en los síntomas depresivos y la depresión perinatal como factores de predicción de MIRQ. Mientras que la depresión materna se asocia con una MIRQ inferior al nivel óptimo, los resultados no son consistentes. Las características de la personalidad se asocian con la crianza y la tendencia a la depresión, lo cual presenta un posible punto adicional a la evaluación de salud mental prenatal. Llevamos a cabo una revisión sistemática de estudios que examinaron la conexión entre síntomas depresivos prenatales y/o características de la personalidad con MIRQ postnatal. Nuestros resultados sugieren que tanto las características maternas de la personalidad como los síntomas depresivos medidos durante el temprano embarazo se asocian con MIRQ postnatal. Una medición de las características de la personalidad pudiera mejorar la evaluación de salud mental prenatal lo cual permitiría oportunidades para la intervención enfocada a partir del embarazo con miras a mejorar MIRQ, la crianza, los resultados de salud mental maternos, así como el desarrollo sicosocial y sicológico del infante, contribuyendo así a reducir la carga humana y económica.

Les troubles mentaux maternels peuvent avoir un impact important sur le développement psychosocial et psychologique des enfants menant à des coûts personnels et économiques continus et importants. Un mécanisme de médiation clé est la qualité de la relation mère-nourrisson (ici abrégé en français QRMN). Les études de recherché et les initiatives de dépistage en santé mentale périnatale ont surtout porté sur les symptômes dépressifs et la dépression périnatale en tant que prédicteurs de la QRMN. Mais alors que la dépression maternelle est liée à une QRMN sous-optimale, les résultats ne sont pas uniformes et constants. Les caractéristiques de personnalité sont liées au parentage et à la propension à la dépression, présentant un ajout potentiel à l'évaluation de santé mentale prénatale. Nous avons passé en revue systématiquement toutes les études ayant examiné le lien entre les symptômes dépressifs périnataux et / ou les caractéristiques de personnalité avec une QRMN postnatale. Nos recherches suggèrent que les traits de personnalité maternelle et les symptômes dépressifs mesurés durant le début de la grossesse sont à la fois liés à la QRMN postnatale. Une mesure de caractéristiques de personnalité pourrait améliorer l'évaluation de la santé mentale prénatale et offrir des possibilités d'intervention ciblée commençant durant la grossesse, afin d'améliorer la QRMN, le parentage et les résultats de santé mentale maternelle, ainsi que le développement psychosocial et psychologique du nourrisson, contribuant donc à la réduction de la charge du coût humain et économique.

Many naps, one nap, none: A systematic review and meta-analysis of napping patterns in children 0-12 years.

The onset of monophasic sleep, in which napping ceases and sleep consolidates into a single night period, is a key developmental milestone of childhood. Yet to date, there is little consensus regarding the timing of cessation of napping in children. The aim of the current study is to examine global evidence regarding napping patterns in childhood, and, through meta-analysis, describe patterns of napping cessation and duration observed in children aged 0-12 y. A systematic search of all published, original research articles reporting children's napping patterns, by age, was conducted. The quality of studies was assessed, and meta-analysis of eligible studies undertaken. Risk of bias and heterogeneity of measurement was high. Current evidence indicates that less than 2.5% of children cease napping prior to age 2, while 94% cease napping by age 5. The preschool period (3-5 y; 36-60 mo) represents a particularly dynamic period in napping cessation, with large variation in rates of napping across studies evidencing potential ecological effects. Future studies should focus on understanding of the underlying mechanisms explaining individual variations in napping patterns and the extent to which patterns of napping may represent a marker of child development.

Observed compliance with safe sleeping guidelines in licensed childcare services.

OBJECTIVE: To independently assess compliance with safe sleeping guidelines for infants <12 months in licensed childcare services. DESIGN: Full-day, in-situ observations of childcare practices (including sleep and non-sleep periods) conducted in 2016-2017. SETTING: Australian home-based and centre-based licensed childcare services. All subject to national regulation and legislation to comply with safe sleeping guidelines. PARTICIPANTS: The sample was 18 licensed childcare settings (15 centre-based, 3 home-based) that had infants <12 months (n=49) attending at the time of observation. 31 educators completed self-report surveys. MAIN OUTCOMES AND MEASURES: Standard observations of childcare practices, including a 20-item infant Safe Sleeping Guideline checklist. Educator characteristics, including each individual's knowledge, beliefs and attitudes regarding safe sleeping practices. RESULTS: 83% of childcare services were observed to be non-compliant on at least 1 of 20 target guidelines (median 2.5, max=7); 44% were observed placing infants prone/side and 67% used loose bedding, quilts, doonas/duvets, pillows, sheepskins or soft toys in cots. 71% of the childcare settings had a copy of current safe sleeping guidelines displayed either in or at entry to the infant sleep room. CONCLUSION: Despite 25 years of public health messaging, non-compliance with safe sleeping guidelines was observed to be high in childcare services. Understanding of the reasons underlying non-compliance, particularly in contexts were legislative mandate and access to information regarding safe sleeping is high, is critical to informing ongoing public health messaging and should be the focus of future studies.
