The maternal health study: Study design update for a prospective cohort of first-time mothers and their firstborn children from birth to age ten.

BACKGROUND: Maternal health is critical to the health and well-being of children and families, but is rarely the primary focus of pregnancy and birth cohort studies. Globally, poor maternal health and the exposure of women and children to family violence contribute to the perpetuation and persistence of intergenerational health inequalities. OBJECTIVES: The Maternal Health Study was designed to investigate the contribution of social and obstetric risk factors to common maternal physical and psychological morbidities. Over time, our focus has expanded to include mother-child pairs and investigation of intergenerational trauma and family violence. POPULATION: A total of 1507 first-time mothers were recruited in early pregnancy from six public hospitals in Melbourne, Australia, in 2003-2005. METHODS: Women completed questionnaires or telephone interviews in early pregnancy (≤24 weeks); at 32 weeks' gestation; at three, six, nine, 12 and 18 months postpartum; and at four and ten years. At ten years, women and children were invited to participate in face-to-face interviews, which included direct assessment of children's cognitive and language development. A wide range of obstetric, social and contextual factors have been measured, including exposure to intimate partner violence (IPV) (1-year, 4-year and 10-year follow-up). RESULTS: 1507 eligible women were recruited at a mean gestation of 15 weeks. At one year, four years and ten years postpartum, 90.0%, 73.1% and 63.2% of the original cohort took part in follow-up. One in three women in the study (34.5%) reported exposure to IPV in the first ten years of motherhood: 19% in the first 12 months postpartum, 20% in the year prior to four-year follow-up and 18.3% in the year prior to ten-year follow-up. CONCLUSION: The study affords a unique opportunity to examine patterns of maternal and child health and health service use associated with exposure to IPV.

Intimate partner violence and child outcomes at age 10: a pregnancy cohort.

OBJECTIVE: Assess the mental health, physical health, cognitive and language development of 10-year old children in families where mothers have reported intimate partner violence (IPV) compared with children with no reported IPV exposure. DESIGN: Prospective pregnancy cohort. Maternal report of IPV (Composite Abuse Scale) at 1, 4 and 10 years. Maternal and direct assessment of child mental health (probable psychiatric diagnosis, anxiety and emotional/behavioural difficulties), cognition (IQ and executive function), language (general, pragmatic and receptive) and physical health at 10 years. SETTING: A subsample of 615 mother-child dyads drawn from a pregnancy cohort of 1507 nulliparous women recruited from six public hospitals in Melbourne, Australia. RESULTS: Any IPV exposure from infancy to age 10 was associated with poorer child outcomes at age 10. Specifically, twice the odds of a probable psychiatric diagnosis, emotional/behavioural difficulties, impaired language skills (general and pragmatic), and having consulted a health professional about asthma or sleep problems. IPV exposure at age 10 associated with two to three times higher odds of all mental health outcomes, elevated blood pressure and sleep problems. Early life exposure alone (at 1 and/or 4 years) associated with three times higher odds of a general language problem and asthma at age 10. CONCLUSION: The high prevalence of IPV and increased risk of poorer health and development among children exposed highlights the burden of ill health carried by children in families experiencing IPV. Fewer difficulties where exposure was limited to the early years builds the case for better identification, understanding and resourcing of effective early intervention.

The relationship between language difficulties, psychosocial difficulties and speech-language pathology service access in the community.

BACKGROUND: A range of factors may impact whether children access speech-language pathology (SLP) services, beyond their communication difficulties. For instance, co-occurring psychosocial difficulties may amplify children's observable difficulties, leading to greater access. It is important to examine such associations because they may reflect inherent differences between children with language difficulties who access services and those who do not, indicating under-servicing for subgroups in the community. AIMS: The first aim was to examine possible differences in psychosocial difficulties between children with language difficulties who did versus did not access SLP services in the past 12 months. The second aim was to examine the unique contribution of psychosocial difficulties to service access, over and above language difficulties and other common predictors of service access. METHODS & PROCEDURES: Analyses were carried out on data gathered from 808 eleven-year-old children who took part in the Early Language in Victoria Study (ELVS). Children were categorized as having language difficulties based on their CELF-4 Core Language Score with a cut-point of > 1.25 SD below the mean. The primary outcome measure was access to SLP services in the past 12 months. Comparison and predictor variables included children's psychosocial difficulties, language skills, relevant demographic variables (gender, caregiver education) and prior SLP access. OUTCOMES & RESULTS: A total of 42 children with language difficulties who had accessed SLP services had significantly greater psychosocial difficulties than those who had not (SDQ Total Difficulties, U = 53.00, z = -4.080, p < 0.001). Using binary logistic regression, a model examining child gender, caregiver education, psychosocial difficulties (internalizing and externalizing behaviours), language difficulties and prior SLP access (in earlier years) was significant χ2 (8) = 137.285, p< 0.001, with increased externalizing difficulties (OR = 1.213, p < 0.001), increased communication difficulties (OR = 0.949, p < 0.001), and prior SLP access (OR = 7.430, p < 0.001) identified as unique predictors of service access. CONCLUSIONS & IMPLICATIONS: The results indicate that children with language difficulties who have comorbid psychosocial difficulties are more likely to access services than those who do not. Accordingly, children with language difficulties who access clinical services may require interdisciplinary support, while children without co-morbid psychosocial difficulties may be under-referred for SLP services. What this paper adds What is already known on this subject There is evidence that a range of personal and contextual factors impact the likelihood of a person accessing healthcare services beyond the specific issue of concern. What this paper adds to existing knowledge In this population-based study, we provide statistical evidence that children with language difficulties who had higher levels of psychosocial difficulties were more likely to access SLP services than those who had lower levels. What are the potential or actual clinical implications of this work? Children with language difficulties who access SLP services may require support for psychosocial difficulties, while children who do not have comorbid difficulties may be underserviced in the community.

Infant Regulation: Associations with Child Language Development in a Longitudinal Cohort.

OBJECTIVE: To determine whether infants who have regulatory problems (eg, sleeping, crying, and feeding problems) at 1 year of age are at increased risk of experiencing language difficulties at ages 5 and 11 years, compared with settled infants. STUDY DESIGN: Parent survey and child assessment data (n = 1131) were drawn from a longitudinal community cohort study. Latent Class Analysis identified 5 profiles of infant regulation including those who were settled (37%), had tantrums (21%), had sleep problems (25%), were moderately unsettled (13%), and severely unsettled (3%) at 12 months of age. Adjusted regression analyses examined associations between infant regulatory profiles and language ability (Clinical Evaluation of Language Fundamentals-fourth edition) at ages 5 and 11 years. RESULTS: Infants who were moderately unsettled had lower language scores at age 5 (adjusted mean difference, -3.89; 95% CI, -6.92 to -0.86) and were more likely to have language difficulties (aOR, 2.71; 95% CI, 1.28-5.75), than infants who were settled. Infants who were severely unsettled at 12 months of age, had lower language scores at ages 5 (adjusted mean difference, -7.71; 95% CI, -13.07 to -2.36) and 11 (adjusted mean difference, -6.50; 95% CI, -11.60 to -1.39), than infants who were settled. Severely unsettled infants were 5 times more likely to have language difficulties at age 5 than their settled counterparts (aOR, 5.01; 95% CI, 1.72-14.63). CONCLUSIONS: Children at 1 year of age with multiple regulatory problems are at an increased risk for poorer language skills at ages 5 and 11 years.

Predictors in Infancy for Language and Academic Outcomes at 11 Years.

OBJECTIVES: To examine the contribution of early life factors and preschool- and school-aged language abilities to children's 11-year language and academic outcomes. METHODS: Participants (N = 839) were from a prospective community cohort study of 1910 infants recruited at 8 to 10 months of age. Early life factors included a combination of child (prematurity, birth weight), family (socioeconomic disadvantage, family history of language difficulties), and maternal factors (education, vocabulary, and age). Language (standardized assessment of receptive and expressive skills) and academic (national assessment) outcomes at 11 years were predicted by using a series of multivariable regression models. RESULTS: Early life factors explained 11% to 12% of variance in language scores at 11 years. The variance explained increased to 47% to 64% when language scores from 2 to 7 years were included. The largest increase in variance explained was with 4-year language scores. The same early life factors explained 13% to 14% of academic scores at 11 years, with increases to 43% to 54% when language scores from 2 to 11 years were included. Early life factors adequately discriminated between children with typical and low language scores but were much better discriminators of children with typical and low academic scores. When earlier language scores were added to models then the area under the curve increased to 0.9 and above. CONCLUSIONS: Children's language outcomes at 11 years are accurately predicted by their 4-year language ability and their academic outcomes at 11 years are predicted by early family and home environment factors. Children with low language abilities at 11 years consistently performed more poorly on national assessments of literacy and numeracy.

Intimate partner violence, maternal depression, and pathways to children's language ability at 10 years.

Intimate partner violence (IPV) between parents is associated with poorer child language development. This study aimed to examine pathways from IPV and maternal depressive symptoms in children's 1st year to language skills at 10 years. Pathways were examined via IPV, maternal depressive symptoms, and maternal involvement in home learning activities (e.g., reading, storytelling) at age 4. A secondary aim was to examine whether these pathways differed by child gender. Data were drawn from 1,507 mothers and their firstborn children participating in a community-based prospective longitudinal study. At child age 1 and 4 years, mothers reported IPV using the Composite Abuse Scale (CAS) and completed a depression scale. At child age 10 years, mothers completed the Children's Communication Checklist (2nd edition) Short Form and 4 pragmatic subscales, and children completed a receptive vocabulary test. Results provided some evidence that maternal depressive symptoms at 4 years postpartum may be an important mechanism by which exposure to IPV and maternal depressive symptoms in the child's 1st year is associated with poorer language at age 10. These pathways remained evident after accounting for social disadvantage, number of siblings, and concurrent IPV exposure at 10 years. There was little evidence that the pathways were mediated by maternal involvement or differed by gender. Implications for speech pathology, health, and education professionals concern identifying and supporting the language needs of children in family contexts where IPV is present. Intervention strategies for families affected by IPV such as supporting maternal mental health and the mother-child relationship could be extended to support child language development.

Children's language abilities at age 10 and exposure to intimate partner violence in early childhood: Results of an Australian prospective pregnancy cohort study.

BACKGROUND: Approximately one in four children in Australia have mothers who experience intimate partner violence (IPV). These children are at risk of poor mental health. Less is known about their language outcomes, despite evidence that childhood adversity threatens neurodevelopment, and the home environment effects language development. OBJECTIVE: This study aimed to examine the relationship between early childhood IPV exposure and language outcomes (receptive vocabulary, general language, pragmatic language) at age 10, including the influence of maternal depressive symptoms. PARTICIPANTS AND SETTING: Participants were 615 mothers and their first-born child participating in a prospective, community-based pregnancy cohort study in Melbourne. METHODS: Mothers reported their experience of IPV and depressive symptoms in the first and fourth year postpartum. At 10 years postpartum, children's receptive vocabulary was directly assessed and mothers reported on their child's general and pragmatic language skills. RESULTS: Exposure to IPV was related to scores indicating poorer abilities in receptive vocabulary (d=-0.26, p = .009), general language (d = 0.23, p = .047) and pragmatic language skills (d = 0.41, p < .001) at age 10. After adjusting for maternal depressive symptoms, evidence remained for the relationship with pragmatic language (d=-0.32, p = .006), and a trend for receptive vocabulary (d=-0.20, p = .052). CONCLUSIONS: At a community-level, children whose mothers experienced IPV during the child's first four years had poorer language skills in middle childhood than children whose mothers did not experience IPV. This is important because poor child language skills are associated with adverse outcomes across the lifespan including academic under-achievement and mental health problems. Clinical implications are discussed.

Infant sleep and child mental health: a longitudinal investigation.

OBJECTIVE: To determine whether infants with severe persistent sleep problems are at increased risk of (1) meeting diagnostic criteria for a psychiatric disorder (age 10 years), and (2) having elevated symptoms of mental health difficulties (ages 4 and 10 years), in comparison with infants with settled sleep. DESIGN AND SETTING: Prospective longitudinal community cohort study-the Maternal Health Study. Mothers completed questionnaires/interviews at 15 weeks' gestation; 3, 6, 9 and 12 months post partum; and when their child turned 4 and 10 years old. Measures included parental report of infant night waking and sleep problems and child mental health (Strengths and Difficulties Questionnaire; Spence Children's Anxiety Scale; Development and Well-being Assessment). PARTICIPANTS: 1460 mother-infant dyads. RESULTS: 283 (19.4%) infants had persistent severe sleep problems, 817 (56.0%) had moderate/fluctuating sleep problems and 360 (24.7%) infants were settled. Infants with persistent severe sleep problems were more likely to report emotional symptoms at age 4 (adjusted odds ratio (AOR)=2.70, 95% CI 1.21 to 6.05, p=0.02), and meet diagnostic criteria for an emotional disorder at age 10 (AOR=2.37, 95% CI 1.05 to 5.36, p=0.04). Infants with persistent severe sleep problems also had elevated symptoms of separation anxiety (AOR=2.44, 95% CI 1.35 to 4.41, p<0.01), fear of physical injury (AOR=2.14, 95% CI 1.09 to 4.18, p=0.03) and overall elevated anxiety (AOR=2.20, 95% CI 1.13 to 4.29, p=0.02) at age 10. CONCLUSIONS: Infants with persistent severe sleep problems during the first postnatal year have an increased risk of anxiety problems and emotional disorders at age 10.

Prevalence and features of comorbid stuttering and speech sound disorder at age 4 years.

BACKGROUND: Stuttering and speech sound disorder may co-occur during early childhood, although the exact rate of comorbidity in a community-cohort sample remains unknown. In isolation, both disorders have the potential for long-term negative effects. Comorbidity rates of 16%-46% reported in previous studies were based on parent report, speech-language therapist surveys, case file audits or direct observation studies from clinical samples. Rigorous methodology utilising a prospective, longitudinal community-cohort design is required to support these previous findings. AIMS: First, to identify the proportion of children with comorbid stuttering and speech sound disorder at 4 years of age drawn from a community-cohort study. Second, to compare demographic and clinical features of this comorbid diagnosis group compared to children with no diagnosis of either disorder, or those with either disorder in isolation. METHODS & PROCEDURES: Participants were drawn from a prospective, longitudinal community cohort study (the Early Language in Victoria Study) at 4 years of age (n = 1607). Demographic and clinical features for comparison were theoretically driven and included: gender, birth history, feeding status, speech and language status, family history of communication difficulties, maternal education, maternal vocabulary, maternal mental health and socioeconomic status. OUTCOMES & RESULTS: Of the 160 children diagnosed with stuttering between 2 and 4 years of age, 6.88 % (n = 11) also had a speech sound disorder. Given the small sample size and number of comparisons performed, there was insufficient evidence to rule out that group differences observed were not simply due to chance. CONCLUSIONS & IMPLICATIONS: The prevalence of comorbid stuttering and speech sound disorder was lower in a community cohort compared to that reported in clinical studies. Higher rates reported in clinical samples may be due to increased parental help-seeking behaviour when the two disorders co-occur. Subsequently, these children may present to clinics more frequently. Accurate representation of prevalence allows for population specific research on best practice assessment and intervention. Currently little is known about how best to manage this caseload, therefore more research is required in this area, including the determination of prognostic variables to provide efficient and effective management.

The development and validation of the Short Language Measure (SLaM): A brief measure of general language ability for children in their first year at school.

BACKGROUND: There is no sufficiently accurate short-language measure that could be used by speech-language pathologists, teachers or paraprofessionals to screen young school-aged children to identify those requiring in-depth language evaluations. This may be due to poor development of the available measures, which have omitted crucial test development steps. Applying more stringent development procedures could result in a measure with sufficient accuracy. AIMS: To create and validate a short-language measure that has acceptable accuracy, validity and reliability, and which can be used to identify children who require further assessment and/or referral to speech-language services. METHODS & PROCEDURES: The study consisted of two phases. In Phase 1 (measure creation), 56 children were assessed with 160 direction-following and sentence-recall test items and a reference measure, the Clinical Evaluation of Language Fundamentals-Fourth Edition (CELF-4). Items were then examined for their individual characteristics (validity, reliability, difficulty and discrimination) via item analysis and the highest quality items were selected to form the Short Language Measure (SLaM). In Phase 2 (measure validation), 126 children were assessed with the SLaM and the reference measure (CELF-4) to determine SLaM's accuracy, validity and reliability. OUTCOMES & RESULTS: A total of 40 test items were selected to form SLaM in Phase 1. Findings from Phase 2 indicated that SLaM had an accuracy of 94% (sensitivity = 94%, specificity = 93%), validity of 0.89 and reliability of 0.93. These values remained relatively consistent across both phases. CONCLUSIONS & IMPLICATIONS: The results indicated that SLaM has excellent psychometric properties. It can be used to identify children who need further evaluation by a speech-language pathologist. What this paper adds What is already known on this subject Prior research suggests that combining a direction-following and a sentence-recall task has sufficient discrimination accuracy and agreement with an omnibus language measure. Trialling a large set of direction-following and sentence-recall test items to select those with the highest individual characteristics could result in an effective short-language measure. What this paper adds to existing knowledge A short-language measure (SLaM) was created and validated on two independent samples of children. Items with the highest validities, reliabilities and discrimination capacities were selected to form SLaM. This procedure resulted in a measure with high validity and reliability that exceeded the criterion for adequate discrimination accuracy. What are the potential or actual clinical implications of this work? SLaM is an effective measure that can accurately identify children who require detailed evaluations by speech-language pathologists.

Profiles and Predictors of Infant Sleep Problems Across the First Year.

OBJECTIVE: To identify profiles and predictors of maternal-reported infant sleep problems across the first postnatal year. METHODS: Survey data examining maternal mental and physical health, intimate partner violence (IPV), and infant sleep problems and night waking were gathered from a cohort of 1,460 nulliparous women at 15 weeks' gestation and when their infants were 3, 6, 9, and 12 months old. RESULTS: Latent class analysis revealed 5 profiles of infant sleep problems, including those who had few problems (24.7%), persistent moderate problems (27.3%), increased problems at 6 months (10.8%), increased problems at 9 months (17.8%), and persistent severe problems (19.4%). Persistent severe infant sleep problems were associated with prepartum and postpartum maternal depression (adjusted odds ratio [AOR] 2.13, 95% confidence interval [CI] 1.35-3.34, p < 0.01; AOR 2.52, 95% CI 1.64-3.87, p < 0.001, respectively), poorer prepartum and postpartum perception of health (adjusted mean difference [AMD] 23.48, 95% CI 24.9 to 22.1, p < 0.01; AMD 23.78, 95% CI 25.2 to 22.4, p < 0.001, respectively), increased postpartum anxiety (AOR 2.22, 95% CI 1.26-3.90, p < 0.01), and increased prevalence of IPV in the first year postpartum (AOR 1.86, 95% CI 1.20-2.87, p < 0.01). CONCLUSION: Poorer prepartum and postpartum maternal mental and physical health, and IPV, were associated with maternal report of persistent severe infant sleep problems. Women experiencing prenatal physical and mental health difficulties may benefit from advice on managing infant sleep and settling. Health professionals working with unsettled infants must be equipped to enquire about and respond appropriately to disclosures of IPV.

Infant Regulation and Child Mental Health Concerns: A Longitudinal Study.

: media-1vid110.1542/5984232215001PEDS-VA_2018-0977Video Abstract OBJECTIVES: To examine profiles of infant regulatory behaviors and associated family characteristics in a community sample of 12-month-old infants and mental health difficulties at 5 and 11 years of age. METHODS: Items relating to demographic characteristics, maternal distress, and infant regulation were completed by 1759 mothers when their infants were 8 to 12 months old. The Strengths and Difficulties Questionnaire was completed by mothers at child ages 5 (n = 1002) and 11 (n = 871) years. RESULTS: Analyses revealed 5 profiles ranging from the most settled infants (36.8%) to those with mainly sleep problems (25.4%), isolated mild-to-moderate tantrums (21.3%), complex regulatory difficulties (13.2%), and complex and severe regulatory difficulties (3.4%). Compared with those in the settled profile, children in the moderately unsettled profile were more likely to score in the clinical range for total difficulties at 11 years of age (odds ratio [OR] 2.85; 95% confidence interval [CI]: 1.28 to 6.36; P < .01), and children in the severely unsettled profile were more likely to score in the clinical range at 5 (OR 9.35; 95% CI: 2.49 to 35.11; P < .01) and 11 years of age (OR 10.37; 95% CI: 3.74 to 28.70; P < .01). CONCLUSIONS: Infants with multiple moderate-to-severe regulatory problems experience substantially heightened odds of clinically significant mental health concerns during childhood, and these symptoms appear to worsen over time. Clinicians must inquire about the extent, complexity, and severity of infant regulatory problems to identify those in the most urgent need of intervention and support.

Prevalence, comorbidity and factors associated with sleeping, crying and feeding problems at 1 month of age: A community-based survey.

AIM: To examine, in a community cohort of healthy one-month-old infants, (i) the prevalence of early infant sleeping, crying and feeding problems; (ii) the extent to which they co-exist; and (iii) infant and mother characteristics associated with each problem alone and with comorbid problems. METHODS: A survey at 4 weeks of infant age examined the presence of infant sleeping, crying and feeding problems (yes/no); parenting self-efficacy; rating of self as a tense person; and doubts about parenting at bedtime. RESULTS: A total of 770 mothers (39% of those approached) with a total of 781 infants (11 twins) took part. Infant sleeping, crying and feeding problems were reported by 38.5, 27.4 and 25.2% of mothers, respectively. On comorbidity, 25.5% reported one problem, 20.5% reported two and 7.3% reported all three problems. Mothers of first-born infants reported more crying problems and comorbid problems. Mothers who described themselves as a 'tense person' reported more infant feeding problems. Maternal doubt and low self-efficacy were consistently associated with each type of infant problem and comorbid problems (adjusting for other factors). CONCLUSION: Mothers expressing doubt and low parenting self-efficacy may benefit from additional support and guidance on normal infant behaviour.

Behavioral Outcomes of Infant Colic in Toddlerhood: A Longitudinal Study.

OBJECTIVE: To assess whether infants with colic that resolved before 6 months of age have poorer medium-term outcomes than infants without colic. STUDY DESIGN: Comparative study of 2 prospective, community-based cohorts of children aged 2-3 years in Melbourne, Australia: children from the Baby Biotics study, with previously diagnosed Wessel criteria of colic without problem crying at 6 months (True Colic Cohort), vs children from the Baby Business trial, without problem crying at 1, 4, and 6 months (No Colic Cohort). Caregiver report of child internalizing and externalizing behaviors (primary outcome), temperament, regulatory (crying/sleeping/feeding) problems, and family functioning at child age 2-3 years was collected. We conducted regression analyses of mean differences/ORs adjusted for child sex, age, social disadvantage, parental education, and maternal mental health. RESULTS: In total, 74% of the original Baby Biotics (n = 124) sample and 75% of the Baby Business (n = 503) sample completed questionnaires. In adjusted analyses, there were no significant differences between the True Colic Cohort (n = 99) and No Colic Cohort (n = 182) in internalizing behavior problems (adjusted mean difference 0.73; 95% CI -3.96 to 5.43, P = .76) or externalizing behavior problems (adjusted mean difference -1.53; 95% CI -6.02 to 2.97, P = .51). There were no statistically significant differences between groups in temperament, parental perception of regulatory problems, or family functioning. CONCLUSIONS: Infants with colic whose crying self-resolves do not experience adverse effects regarding child behavior, regulatory abilities, temperament, or family functioning in the medium term. Parents and clinicians can be reassured that infant crying as the result of colic, and related stress, is short-lived and will likely resolve.

Investigation of the language tasks to include in a short-language measure for children in the early school years.

BACKGROUND: The inaccurate estimation of language difficulties by teachers suggests the benefit of a short-language measure that could be used to support their decisions about who requires referral to a speech-language therapist. While the literature indicates the potential for the development of a short-language measure, evidence is lacking about which combination of language tasks it should include. AIMS: To understand the number and nature of components/language tasks that should be included in a short-language measure for children in the early school years. METHODS & PROCEDURES: Eight language tasks were administered to participants of the Early Language in Victoria Study (ELVS) at ages 5 (n = 995) and 7 (n = 1217). These included six language tasks measured by an omnibus language measure (which comprised a direction-following, morphological-completion, sentence-recall, sentence-formation, syntactic-understanding and word-association task) and a non-word repetition and a receptive vocabulary task, measured by two task-specific language measures. Scores were analyzed using principal component analysis (PCA), the Bland and Altman method, and receiver operating characteristic (ROC) curve analysis. OUTCOMES & RESULTS: PCA revealed one main component of language that was assessed by all language tasks. The most effective combination of two tasks that measured this component was a direction-following and a sentence-recall task. It showed the greatest agreement with an omnibus language measure and exceeded the criterion for good discriminant accuracy (sensitivity = 94%, specificity = 91%, accuracy = 91%, at 1 SD (standard deviation) below the mean). CONCLUSIONS & IMPLICATIONS: Findings support the combination of a direction-following and a sentence-recall task to assess language ability effectively in the early school years. The results could justify the future production of a novel short-language measure comprising a direction-following and a sentence-recall task to use as a screening tool in schools and to assess language ability in research participants.

Subgroups in language trajectories from 4 to 11 years: the nature and predictors of stable, improving and decreasing language trajectory groups.

BACKGROUND: Little is known about the nature, range and prevalence of different subgroups in language trajectories extant in a population from 4 to 11 years. This hinders strategic targeting and design of interventions, particularly targeting those whose difficulties will likely persist. METHODS: Children's language abilities from 4 to 11 years were investigated in a specialist language longitudinal community cohort (N = 1,910). Longitudinal trajectory latent class modelling was used to characterise trajectories and identify subgroups. Multinomial logistic regression was used to identify predictors associated with the language trajectories children followed. RESULTS: Three language trajectory groups were identified: 'stable' (94% of participants), 'low-decreasing' (4%) and 'low-improving' (2%). A range of child and family factors were identified that were associated with following either the low-improving or low-increasing language trajectory; many of them shared. The low-improving group was associated with mostly environmental risks: non-English-speaking background, social disadvantage and few children's books in the home. The low-decreasing group was associated with mainly biological risks: low birth weight, socioemotional problems, lower family literacy and learning disability. CONCLUSIONS: By 4 years, services can be confident that most children with low language will remain low to 11 years. Using rigid cut-points in language ability to target interventions is not recommended due to continued individual variability in language development. Service delivery models should incorporate monitoring over time, targeting according to language abilities and associated risks and delivery of a continuum of interventions across the continuum of need.

Language Outcomes at 7 Years: Early Predictors and Co-Occurring Difficulties.

OBJECTIVE: To examine at 7 years the language abilities of children, the salience of early life factors and language scores as predictors of language outcome, and co-occurring difficulties METHODS: A longitudinal cohort study of 1910 infants recruited at age 8 to 10 months. Exposures included early life factors (sex, prematurity, birth weight/order, twin birth, socioeconomic status, non-English speaking background,family history of speech/language difficulties); maternal factors (mental health, vocabulary, education, and age); and child language ability at 2 and 4 years. Outcomes were 7-year standardized receptive or expressive language scores (low language: ≥1.25 SD below the mean), and co-occurring difficulties (autism, literacy, social, emotional, and behavioral adjustment, and health-related quality of life). RESULTS: Almost 19% of children (22/1204;18.9%) met criteria for low language at 7 years. Early life factors explained 9-13% of variation in language scores, increasing to 39-58% when child language scores at ages 2 and 4 were included. Early life factors moderately discriminated between children with and without low language (area under the curve: 0.68-0.72), strengthening to good discrimination with language scores at ages 2 and 4 (area under the curve: 0.85-0.94). Low language at age 7 was associated with concurrent difficulties in literacy, social-emotional and behavioral difficulties, and limitations in school and psychosocial functioning. CONCLUSIONS: Child language ability at 4 years more accurately predicted low language at 7 than a range of early child, family, and environmental factors. Low language at 7 years was associated with a higher prevalence of co-occurring difficulties.

Depression and anger in fathers of unsettled infants: A community cohort study.

AIM: To examine the relationship between unsettled infant behaviour and fathers' depressive symptoms, cognitions surrounding infant sleep (anger, doubt), and personal sleep, in a community cohort. METHODS: Data were collected from 102 fathers of healthy infants at 4 weeks, 4 months and 6 months of age. Measures included father report of infant sleep and crying problems, depressive symptoms, cognitions about infant sleep and own sleep quality and quantity. Data were analysed using adjusted regression models. RESULTS: Sleep problems at 4 months of age were associated with increased depressive symptoms (adjusted mean difference 2.64 (1.27-4.00)), doubt (adjusted mean difference 1.82 (0.40-3.25)), anger (adjusted mean difference 1.86 (0.51-3.20)), poor personal sleep quantity (adjusted odds ratio (OR) 0.21; 95% confidence interval (CI) 0.09-0.51) and quality (adjusted OR 0.20; 95% CI 0.08-0.51); and at 6 months of age, with increased depressive symptoms (adjusted mean difference 2.56 (1.28-3.84)), anger (adjusted mean difference 1.63 (0.40-2.87)), poor personal sleep quantity (adjusted OR 0.14; 95% CI 0.05-0.38) and quality (adjusted OR 0.28; 95% CI 0.11-0.72). Infant cry problems at 4 months were associated with increased anger (adjusted mean difference 1.98 (0.60-3.36)) and doubt (adjusted mean difference 1.55 (0.05-3.05)); and at 6 months, with increased depressive symptoms (adjusted mean difference 3.04 (1.59-4.69)), anger (adjusted mean difference 2.73 (1.29-4.17)) and less personal sleep (adjusted OR 0.22; 95% CI 0.07-0.71). CONCLUSION: Fathers of unsettled infants reported greater anger towards their infant and increased depressive symptoms by 4 months infant age, with these symptoms persisting 2 months later. Evidence-based interventions are needed for these fathers.

Health service use and costs for infant behaviour problems and maternal stress.

AIM: We aim to describe health service (HS) use in the first 6 months post-partum and to examine the associations between service costs, infant behaviour and maternal depressive symptoms. METHODS: Participants were 781 infants and mothers in Melbourne, Australia. Mothers reported infant feeding, sleeping and crying problems, depressive symptoms and health service use. Costs were valued in 2012 Australian dollars. RESULTS: The most common services used were maternal child health nurses, general practitioners (GP) and allied health. Infant feeding problems were associated with increased costs for services relevant to infant behaviour including maternal child health nurses (P = 0.007), GP (P = 0.008) and paediatricians (P = 0.03). Maternal depressive symptoms were associated with increased costs for services relevant to depressive symptoms including parenting centres (P = 0.04), GP (P = 0.004), psychiatrists (P = 0.02) and psychologists (P = 0.001). Mothers who completed high school had higher service costs for infant problems than those with lower education (P = 0.02). Single mothers had higher costs for services used for their depressive symptoms than partnered mothers (P < 0.001). Mothers with English as a second language had lower service costs for their depressive symptoms (P = 0.02). CONCLUSIONS: Infant feeding problems and maternal depressive symptoms are associated with higher costs for health services relevant to these conditions. Cost-effective strategies to manage these conditions are needed with accessibility being ensured for mothers who are experiencing social adversity.
