RESUMEN

Violence is a major public health problem globally, with the highest rates in low- and middle-income countries (LMICs) in the Americas and southern Africa. Parenting programmes in high-income countries can diminish risk for violence, by reducing risk factors such as child aggression and harsh parenting, and increasing protective factors such as child cognitive development and school readiness. However, there is critical need to identify low-cost programmes with replicable benefits that work in real-world LMICs contexts. A three-arm, randomised, single-blind trial evaluated effects of two low-cost, group-based parenting programmes recommended for LMICs (ACT: Raising Safe Kids; DBS: dialogic book-sharing) on child aggression (primary outcome), child development, parenting, maltreatment, and stress. Participants were 369 children with medium-high levels of aggression (mean age 3.1 years at baseline) in poor households. Interventions were implemented in city health and education services in southern Brazil. Maternal reports, filmed observations, child tasks, and hair cortisol were assessed at baseline, 1-month post-intervention, and 8-month follow-up. Intention-to-treat analyses compared each of ACT and DBS with a control group. Three hundred sixty-eight (99.7%) participants completed follow-up assessments 8 months after the interventions. There was no effect of ACT (standardised mean difference, SMD 0.11, 95% CI - 0.05, 0.27) or DBS (SMD 0.05, 95% CI - 0.11, 0.21) on the primary outcome of child aggression. ACT reduced harsh parenting behaviour post-intervention (SMD - 0.23; 95% CI - 0.46, - 0.01), but not at follow-up. DBS improved book-sharing practices at both time points (e.g., maternal sensitivity at follow-up SMD 0.33; 95% CI 0.08, 0.57). There were no benefits of either programme for other parenting, child development, or stress outcomes. Two parenting programmes in Brazil had small effects on parenting practices but did not reduce child aggression or several other important risk/protective factors for violence. Effective early interventions that reduce violence in real-world LMIC settings are highly desirable but may be challenging to achieve.

RESUMEN

BACKGROUND: Child cognitive development is often compromised in contexts of poverty and adversity, and these deficits tend to endure and affect the child across the life course. In the conditions of poverty and violence that characterise many low- and middle-income countries (LMIC), the capacity of parents to provide the kind of care that promotes good child development may be severely compromised, especially where caregivers suffer from depression. One avenue of early intervention focuses on the quality of the early mother-infant relationship. The aim of this study was to examine the long-term impact of an early intervention to improve the mother-infant relationship quality on child cognitive outcomes at 13 years of age. We also estimated the current costs to replicate the intervention. METHOD: We re-recruited 333 children from an early childhood maternal-infant attachment intervention, 'Thula Sana', when the children were 13 years old, to assess whether there were impacts of the intervention on child cognitive outcomes, and maternal mood. We used the Kaufman Assessment Battery to assess the child cognitive development and the Patient Health Questionnaire (PHQ-9) and the Self-Reporting Questionnaire (SRQ-20) to assess maternal mental health. RESULTS: Effect estimates indicated a pattern of null findings for the impact of the intervention on child cognitive development. However, the intervention had an effect on caregiver psychological distress (PHQ-9, ES = -0.17 [CI: -1.95, 0.05] and SRQ-20, ES = -0.30 [CI: -2.41, -0.19]), but not anxiety. The annual cost per mother-child pair to replicate the Thula Sana intervention in 2019 was estimated at ZAR13,365 ($780). CONCLUSION: In a socio-economically deprived peri-urban settlement in South Africa, a home visiting intervention, delivered by community workers to mothers in pregnancy and the first six postpartum months, had no overall effect on child cognitive development at 13 years of age. However, those caregivers who were part of the original intervention showed lasting improvements in depressed mood. Despite the fact that there was no intervention effect on long-term child outcomes, the improvements in maternal mood are important.

RESUMEN

This study evaluated the impact of a parenting intervention on children's cognitive and socioemotional development in a group of caregivers and their 21-to-28-month-old children in a low-income South African township. A randomized controlled trial compared an experimental group (n = 70) receiving training in dialogic book-sharing (8 weekly group sessions) with a wait-list control group (n = 70). They were assessed before the intervention, immediately following it, and at a six month follow-up. The intervention had positive effects on child language and attention, but not behavior problems, prosocial behavior, or theory of mind. Intervention caregivers were less verbally and psychologically harsh, showed more sensitivity and reciprocity and more complex cognitive talk. This program benefitted parenting and child development and holds promise for low-income contexts.

RESUMEN

Little is known about early predictors of later cystic fibrosis (CF) structural lung disease. This study examined early predictors of progressive structural lung abnormalities in children who completed the Australasian CF Bronchoalveolar Lavage (ACFBAL) clinical trial at age 5-years and participated in an observational follow-up study (CF-FAB).Eight Australian and New Zealand CF centres participated in CF-FAB and provided follow-up chest computed-tomography (CT) scans for children who had completed the ACFBAL study with baseline scans at age 5-years. CT scans were annotated using PRAGMA-CF scoring. Ordinal regression analysis and linear regression were used to investigate associations between PRAGMA-CF (Perth-Rotterdam Annotated Grid Morphometric Analysis for CF) outcomes at follow-up and variables measured during the ACFBAL study.99 out of 157 ACFBAL children (mean±sd age 13±1.5 years) participated in the CF-FAB study. The probability of bronchiectasis at follow-up increased with airway disease severity on the baseline CT scan. In multiple regression (retaining factors at p<0.05) the extent of bronchiectasis at follow-up was associated with baseline atelectasis (OR 7.2, 95% CI 2.4-22; p≤ 0.001), bronchoalveolar lavage (BAL) log2 interleukin (IL)-8 (OR 1.2, 95% CI 1.05-1.5; p=0.010) and body mass index z-score (OR 0.49, 95% CI 0.24-1.00; p=0.05) at age 5 years. Percentage trapped air at follow-up was associated with BAL log2 IL-8 (coefficient 1.3, 95% CI 0.57-2.1; p<0.001) at age 5 years.The extent of airway disease, atelectasis, airway inflammation and poor nutritional status in early childhood are risk factors for progressive structural lung disease in adolescence.

RESUMEN

BACKGROUND: Social anxiety disorder (SAD) aggregates in families. To elucidate intergenerational transmission of risk, we examined whether childhood SAD and symptoms of anxiety were prospectively predicted by stable infant temperamental inhibition, maternal SAD, maternal generalized anxiety disorder (GAD) and maternal parenting behaviours. METHODS: We conducted a longitudinal study beginning prenatally with follow-up at 4, 10, 14 and 58 months postnatally. Mothers were assessed for anxiety disorders prenatally and assigned to one of three groups: SAD (n = 67), GAD (n = 56) and nonanxious controls (n = 94). We assessed infant temperamental inhibition at 4 and 14 months, maternal parenting behaviours at 10 and 58 months, and child anxiety disorders and symptoms at 58 months. RESULTS: Child SAD at 58 months was predicted by prenatal maternal SAD (OR = 23.76, 95% CI = 1.15-60.37), but not by prenatal maternal GAD (OR = 7.44, 95% CI = 0.32-124.49), stable temperamental inhibition or maternal behaviours. Child anxiety symptoms at 58 months were predicted specifically by maternal SAD (but not GAD), and also by concurrent maternal intrusiveness. Stable temperamental inhibition moderated the association between 10-month maternal encouragement and 58-month child anxiety symptoms. CONCLUSIONS: We found evidence for specificity of risk for child SAD and anxiety symptoms from maternal SAD compared to maternal GAD. Childhood anxiety symptoms were also predicted by an interaction between a lack of maternal encouragement in infancy and stable temperamental inhibition, as well as concurrent maternal intrusiveness. The findings have clinical implications for targeted prevention of child anxiety.

RESUMEN

BACKGROUND: This study evaluated whether clinical and economic outcomes from CBT for child anxiety disorders in the context of maternal anxiety disorders are improved by adding treatment focused on (a) maternal anxiety disorders or (b) mother-child interactions. METHODS: Two hundred and eleven children (7-12 years, 85% White British, 52% female) with a primary anxiety disorder, whose mothers also had a current anxiety disorder, were randomised to receive (a) child-focused CBT with nonspecific control interventions (CCBT+Con), (b) CCBT with CBT for the maternal anxiety disorder (CCBT+MCBT), or (c) CCBT with an intervention targeting the mother-child interaction (CCBT+MCI). A cost-utility analysis from a societal perspective was conducted using mother/child combined quality-adjusted life years (QALYs). [Trial registration: https://doi.org/10.1186/isrctn19762288]. RESULTS: MCBT was associated with immediate reductions in maternal anxiety compared to the nonspecific control; however, after children had also received CCBT, maternal outcomes in the CCBT+MCI and CCBT+Con arms improved and CCBT+MCBT was no longer superior. Neither CCBT+MCBT nor CCBT+MCI conferred a benefit over CCBT+Con in terms of child anxiety disorder diagnoses post-treatment [primary outcome] (adj RR: 1.22 (95% CI: 0.88, 1.67), p = .23; adj RR: 1.21 (95% CI: 0.88, 1.65), p = .24, respectively) or global improvement ratings (adj RR: 1.25 (95% CI: 0.99, 1.57), p = .06; adj RR: 1.18 (95% CI: 0.93, 1.50), p = .17) or six and 12 months later. No significant differences between the groups were found on the main economic outcome measures (child/mother combined QALY mean difference: CCBT+MCBT vs. CCBT+Con: -0.04 (95% CI: -0.12, 0.04), p = .29; CCBT+MCI vs. CCBT+Con: 0.02 (95% CI: -0.05, -0.09), p = .54). CCBT+MCI was associated with nonsignificantly higher costs than CCBT (mean difference: £154 (95% CI: -£1,239, £1,547), p = .83) but, when taking into account sampling uncertainty, it may be cost-effective compared with CCBT alone. CONCLUSIONS: Good outcomes were achieved for children and their mothers across treatment arms. There was no evidence of significant clinical benefit from supplementing CCBT with either CBT for the maternal anxiety disorder or treatment focussed on mother-child interactions, but the addition of MCI (and not MCBT) may be cost-effective.

RESUMEN

Interventions that train parents to share picture books with children are seen as a strategy for supporting child language development. We conducted meta-analyses using robust variance estimation modeling on results from 19 RCTs (Ntotal  = 2,594; Mchildage  = 1-6 years). Overall, book-sharing interventions had a small sized effect on both expressive language (d = 0.41) and receptive language (d = 0.26). They had a large effect on caregiver book-sharing competence (d = 1.01). The impact of the intervention on child language was moderated by intervention dosage, with lower dosage associated with a minimal impact. Child age and caregiver education level were unrelated to child outcome. This review and meta-analysis confirms the promise of book-sharing interventions for enhancing and accelerating child language development.

RESUMEN

BACKGROUND: Maternal-infant feeding interactions are a primary context for engagement between mothers and their infants, and constitute a unique space in which reciprocity, attunement and maternal sensitivity can be expressed. Increasingly, research demonstrates the importance of the psychological and social nature of the feeding context, and how it may be affected by maternal mental state, feeding skills and sensitivity. As such, feeding interactions may provide useful contexts for observations of maternal sensitivity, reflecting well on day-to-day maternal sensitivity. AIMS AND OBJECTIVES: This paper is a post hoc examination of the impact of an intervention on maternal sensitivity during a feeding interaction when the infants were 6 months old. PARTICIPANTS: A total of 449 women consented to participate in the original intervention and were randomly assigned to the intervention or control groups. Mothers and infants were assessed during pregnancy, and then at 2, 6, 12 and 18 months of infant age. At the 6 month follow-up visit, 79% (354 out of 449) of the participants were retained. Post hoc analyses were conducted on the original sample to determine breastfeeding status. Sixty-nine percent of the women completed the feeding observation at the 6 months follow-up visit, of which 47% reported exclusively breastfeeding and 22% reported bottle-feeding. RESULTS: Results demonstrated that during a feeding interaction, maternal sensitivity was significantly improved among non-breastfeeding mothers who received the intervention. Particularly, maternal responsiveness to infant cues and synchronous interactions was higher among non-breastfeeding intervention mothers compared to control group mothers. The results also show that non-breastfeeding mothers who received the intervention were significantly less intrusive in their interactions with their infants. CONCLUSION: The intervention had particular beneficial effects for mothers who were not breastfeeding and suggest that the intervention offered a protective effect for non-breastfeeding mothers.


Trasfondo: Las interacciones materno-infantiles de alimentación son un contexto primario de compromiso interactivo entre madres y sus infantes. Alimentar al infante es un proceso complejo que requiere no sólo que se provean los nutrientes, sino también una relación social entre el cuidador y el infante. Metas y Objetivos: Este artículo es un examen a posteriori del impacto de una intervención sobre la sensibilidad materna durante una interacción de alimentación cuando los infantes tenían seis meses de edad. Participantes: Un total de 449 mujeres consintieron en participar en la intervención original y fueron asignadas al azar a la propia intervención o a los grupos de control. A la visita de seguimiento de los seis meses, el 79% (354 de las 449) de las participantes aún se mantenían. Se llevaron a cabo análisis a posteriori en el grupo muestra original para determinar la condición de amamantamiento. Resultados: Durante una interacción de alimentación, la sensibilidad materna mejoró significativamente entre las madres que no amamantaban y que recibieron la intervención. La sensibilidad materna a las señales del infante y a las interacciones sincrónicas fue más alta entre madres de la intervención que no amamantaban tal como se les comparó con las madres del grupo de control. Conclusión: Estos resultados demuestran particularmente los efectos beneficiosos para las madres en el grupo de intervención que no estaban amamantando, y sugieren que la intervención ofreció un efecto de protección para las madres que no amamantaban.


Contexte: Les interactions maternelles-bébé durant l'alimentation sont un contexte primaire pour l'engagement entre les mères et leurs bébés. Nourrir son bébé est un processus complexe qui inclut non seulement le transfert d'éléments nutritifs mais également une relation sociale entre la personne prenant soin du bébé et le bébé. Buts et Objectifs: Cet article est une étude post hoc de l'impact d'une intervention sur la sensibilité maternelle durant une interaction d'alimentation lorsque les bébés avaient six mois. Participantes: Un total de 449 femmes ont consenti à participer à l'intervention originelle et ont été réparties au hasard au groupe d'intervention ou au groupe de contrôle. A la visite de suivi de six mois 79% (354 sur 449) des participantes ont été retenues. Les analyses post hoc analyses ont été faites sur l'échantillon d'origine afin de déterminer le statut d'allaitement au sein. Résultats: Durant une interaction d'alimentation, la sensibilité maternelle a été améliorée de manière importante chez les mères de donnant pas le sein qui recevaient l'intervention. La réaction maternelle aux signes du bébé et les interactions synchronisées étaient plus élevées chez les mères du groupe d'intervention de non allaitement au sein comparées au groupe de mères de contrôle. Conclusion: Ces résultats dénotent des effets particulièrement favorables pour les mères du groupe d'intervention qui n'allaitaient pas au sein, et suggèrent que l'intervention a offert un effet protecteur pour les mères n'allaitant pas leurs bébé au sein.

RESUMEN

A considerable body of evidence suggests that early caregiving may affect the short-term functioning and longer term development of the hypothalamic-pituitary-adrenocortical axis. Despite this, most research to date has been cross-sectional in nature or restricted to relatively short-term longitudinal follow-ups. More important, there is a paucity of research on the role of caregiving in low- and middle-income countries, where the protective effects of high-quality care in buffering the child's developing stress regulation systems may be crucial. In this paper, we report findings from a longitudinal study (N = 232) conducted in an impoverished periurban settlement in Cape Town, South Africa. We measured caregiving sensitivity and security of attachment in infancy and followed children up at age 13 years, when we conducted assessments of hypothalamus-pituitary-adrenocortical axis reactivity, as indexed by salivary cortisol during the Trier Social Stress Test. The findings indicated that insecure attachment was predictive of reduced cortisol responses to social stress, particularly in boys, and that attachment status moderated the impact of contextual adversity on stress responses: secure children in highly adverse circumstances did not show the blunted cortisol response shown by their insecure counterparts. Some evidence was found that sensitivity of care in infancy was also associated with cortisol reactivity, but in this case, insensitivity was associated with heightened cortisol reactivity, and only for girls. The discussion focuses on the potentially important role of caregiving in the long-term calibration of the stress system and the need to better understand the social and biological mechanisms shaping the stress response across development in low- and middle-income countries.

RESUMEN

BACKGROUND: Consistent with evidence from high-income countries (HICs), we previously showed that, in an informal peri-urban settlement in a low-middle income country, training parents in book sharing with their infants benefitted infant language and attention (Vally, Murray, Tomlinson, & Cooper, ). Here, we investigated whether these benefits were explained by improvements in carer-infant interactions in both book-sharing and non-book-sharing contexts. We also explored whether infant socioemotional development benefitted from book sharing. METHODS: We conducted a randomized controlled trial in Khayelitsha, South Africa. Carers of 14-16-month-old infants were randomized to 8 weeks' training in book sharing (n = 49) or a wait-list control group (n = 42). In addition to the cognitive measures reported previously, independent assessments were made at base line and follow-up of carer-infant interactions during book sharing and toy play. Assessments were also made, at follow-up only, of infant prosocial behaviour in a 'help task', and of infant imitation of doll characters' nonsocial actions and an interpersonal interaction. Eighty-two carer-infant pairs (90%) were assessed at follow-up. (Trial registration ISRCTN39953901). RESULTS: Carers who received the training showed significant improvements in book-sharing interactions (sensitivity, elaborations, reciprocity), and, to a smaller extent, in toy-play interactions (sensitivity). Infants in the intervention group showed a significantly higher rate of prosocial behaviour, and tended to show more frequent imitation of the interpersonal interaction. Improvements in carer behaviour during book sharing, but not during toy play, mediated intervention effects on all infant cognitive outcomes, and tended to mediate intervention effects on infant interpersonal imitation. CONCLUSIONS: Training in book sharing, a simple, inexpensive intervention that has been shown to benefit infant cognitive development in a low-middle income country, also shows promise for improving infant socioemotional outcomes in this context. Benefits are mediated by improvements in carer-infant interactions, particularly in book-sharing contexts.

RESUMEN

There have been dramatic changes in the care of children with cystic fibrosis (CF) from 1965 to 2015. The initial improvements were the result of incremental gains in medical knowledge and better use of available therapies. Some CF-specific drugs were developed (recombinant human DNase and purified tobramycin for inhalation), but these simply delayed the progression of the lung damage. The discovery of the CF transmembrane conductance regulator gene in 1989 created an explosion of knowledge of airway biology and CF pathophysiology. Now mutation-specific therapy to potentiate mutated CF transmembrane conductance regulator is available for some patients with CF and is transforming their lives. Further advances are eagerly anticipated to benefit all patients with CF.

RESUMEN

BACKGROUND: The ability to regulate emotions is a key developmental achievement acquired during social interactions and associated with better behavioral and social outcomes. We examined the influence of culture on child emotion regulation (ER) and aggression and on early parenting practices, and the role of parenting in child ER. METHODS: We assessed 48 mother-infant dyads from three cultures (1 UK, 2 South African) at infant age of 3 months for maternal sensitivity during face-to-face interactions and responses to infant distress during daily life, and at 2 years for child ER strategies and maternally reported aggression. RESULTS: There were cultural differences in child ER, and these were associated with differences in levels of aggression. Maternal strategies in response to early infant distress also differed by culture and predicted later child ER. Maternal sensitivity during face-to-face interactions was not associated with culture and showed no clear relationship with child ER. CONCLUSION: Cultural differences in maternal responses to infant distress mediated differences in child ER that are, in turn, related to differences in child aggression.

RESUMEN

BACKGROUND: Dialogic book-sharing is an interactive form of shared reading. It has been shown in high income countries (HICs) to be of significant benefit to child cognitive development. Evidence for such benefit in low and middle income countries (LMICs) is scarce, although a feasibility study of our own produced encouraging findings. Accordingly, we aimed to establish the impact on child language and attention of providing training in dialogic booksharing to carers of infants in an impoverished South African community. METHODS: We conducted a randomized controlled trial in Khayelitsha, an informal settlement in South Africa. Mothers of infants aged between 14 and 16 months were recruited and randomized to either 8 weeks of manualized training in dialogic book-sharing or a no-intervention control group. Independent assessments were made of infant language and attention at baseline and following training. The trial was registered (ISRCTN39953901). RESULTS: Ninety one carer-infant dyads were recruited and randomized to the intervention group (n = 49) or the control group (n = 42), 82 (90%) of whom were available for follow-up assessments. On a standardized carer report of infant vocabulary, compared to those in the control group, carers who received the intervention reported a significantly greater increase in the number of words understood by their infants as well as a larger increase in the number of words that their infant understood and could vocalize. Intervention group children also showed substantially greater gains on a measure of sustained attention. CONCLUSIONS: In line with evidence from HICs, a dialogic book-sharing programme delivered to an impoverished South African sample was shown to be of considerable benefit to the development of child language and focussed attention. The training programme, which is simple and inexpensive to deliver, has the potential to benefit child cognitive development in LMIC contexts where such development is commonly compromised.

RESUMEN

BACKGROUND: The quality of the early environment is hypothesized to be an influence on morphological development in key neural areas related to affective responding, but direct evidence to support this possibility is limited. In a 22-year longitudinal study, we examined hippocampal and amygdala volumes in adulthood in relation to early infant attachment status, an important indicator of the quality of the early caregiving environment. METHODS: Participants (N = 59) were derived from a prospective longitudinal study of the impact of maternal postnatal depression on child development. Infant attachment status (35 Secure; 24 Insecure) was observed at 18 months of age, and MRI assessments were completed at 22 years [corrected]. RESULTS: In line with hypotheses, insecure versus secure infant attachment status was associated with larger amygdala volumes in young adults, an effect that was not accounted for by maternal depression history. We did not find early infant attachment status to predict hippocampal volumes. CONCLUSIONS: Common variations in the quality of early environment are associated with gross alterations in amygdala morphology in the adult brain. Further research is required to establish the neural changes that underpin the volumetric differences reported here, and any functional implications.

RESUMEN

BACKGROUND: Models of the development and maintenance of childhood anxiety suggest an important role for parent cognitions: that is, negative expectations of children's coping abilities lead to parenting behaviors that maintain child anxiety. The primary aims of the current study were to (1) compare expectations of child vulnerability and coping among mothers of children with anxiety disorders on the basis of whether or not mothers also had a current anxiety disorder, and (2) examine the degree to which the association between maternal anxiety disorder status and child coping expectations was mediated by how mothers interpreted ambiguous material that referred to their own experience. METHODS: The association between interpretations of threat, negative emotion, and control was assessed using hypothetical ambiguous scenarios in a sample of 271 anxious and nonanxious mothers of 7- to 12-year-old children with an anxiety disorder. Mothers also rated their expectations when presented with real life challenge tasks. RESULTS: There was a significant association between maternal anxiety disorder status and negative expectations of child coping behaviors. Mothers' self-referent interpretations were found to mediate this relationship. Responses to ambiguous hypothetical scenarios correlated significantly with responses to real life challenge tasks. CONCLUSIONS: Treatments for childhood anxiety disorders in the context of parental anxiety disorders may benefit from the inclusion of a component to directly address parental cognitions. Some inconsistencies were found when comparing maternal expectations in response to hypothetical scenarios with real life challenges. This should be addressed in future research.

RESUMEN

Aggression in children is associated with an enhanced tendency to attribute hostile intentions to others. However, limited information is available regarding the factors that contribute to the development of such hostile attribution tendencies. We examined factors that contribute to individual differences in child hostile attributions and aggression, focusing on potential pathways from maternal hostile attributions via negative parenting behavior. We conducted a longitudinal study of 98 mothers and children (47 male, 51 female), recruited from groups experiencing high and low levels of psychosocial adversity. Maternal hostile attributions, observed parenting, and child behaviour were assessed at 18 months and 5 years child age, and child hostile attributions were also examined at 5 years. Independent assessments of maternal and child processes were utilized where possible. Analyses provided support for a direct influence of maternal hostile attributions on the development of child hostile attributions and aggressive behaviour. Maternal hostile attributions were also associated with negative parenting behaviour, which in turn influenced child adjustment. Even taking account of possible parenting influences and preexisting child difficulties, hostile attributions in the mother showed a direct link with child aggression at 5 years. Maternal hostile attributions were themselves related to psychosocial adversity. We conclude that maternal hostile attributions are prevalent in high-risk samples and are related to less optimal parenting behaviour, child hostile attributions, and child aggression. Targeting hostile maternal cognitions may be a useful adjunct to parenting programs.

RESUMEN

OBJECTIVES: To determine whether bronchoalveolar lavage (BAL)-directed therapy for infants and young children with cystic fibrosis (CF), rather than standard therapy, was justified on the grounds of a decrease in average costs and whether the use of BAL reduced treatment costs associated with hospital admissions. STUDY DESIGN: Costs were assessed in a randomized controlled trial conducted in Australia and New Zealand on infants diagnosed with CF after newborn screening and assigned to receive either BAL-directed or standard therapy until they reached 5 years of age. A health care funder perspective was adopted. Resource use measurement was based on standardized data collection forms administered for patients across all sites. Unit costs were obtained primarily from government schedules. RESULTS: Mean costs per child during the study period were Australian dollars (AUD)92 860 in BAL-directed therapy group and AUD90 958 in standard therapy group (mean difference AUD1902, 95% CI AUD-27 782 to 31 586, P = .90). Mean hospital costs per child during the study period were AUD57 302 in the BAL-directed therapy group and AUD66 590 in the standard therapy group (mean difference AUD-9288; 95% CI AUD-35 252 to 16 676, P = .48). CONCLUSIONS: BAL-directed therapy did not result in either lower mean hospital admission costs or mean costs overall compared with managing patients with CF by a standard protocol based upon clinical features and oropharyngeal culture results alone. Following on our previous findings that BAL-directed treatment offers no clinical advantage over standard therapy at age 5 years, flexible bronchoscopy with BAL cannot be recommended for the routine management of preschool children with CF on the basis of overall cost savings.

RESUMEN

Anxious mothers' parenting, particularly transfer of threat information, has been considered important in their children's risk for social anxiety disorder (SAnxD), and maternal narratives concerning potential social threat could elucidate this contribution. Maternal narratives to their preschool 4- to 5-year-old children, via a picture book about starting school, were assessed in socially anxious (N = 73), and nonanxious (N = 63) mothers. Child representations of school were assessed via doll play (DP). After one school term, mothers (Child Behavior Checklist [CBCL]) and teachers (Teacher Report Form) reported on child internalizing problems, and child SAnxD was assessed via maternal interview. Relations between these variables, infant behavioral inhibition, and attachment, were examined. Socially anxious mothers showed more negative (higher threat attribution) and less supportive (lower encouragement) narratives than controls, and their children's DP representations SAnxD and CBCL scores were more adverse. High narrative threat predicted child SAnxD; lower encouragement predicted negative child CBCL scores and, particularly for behaviorally inhibited children, Teacher Report Form scores and DP representations. In securely attached children, CBCL scores and risk for SAnxD were affected by maternal anxiety and threat attributions, respectively. Low encouragement mediated the effects of maternal anxiety on child DP representations and CBCL scores. Maternal narratives are affected by social anxiety and contribute to adverse child outcome.

RESUMEN

BACKGROUND: When caregivers live in remote settings characterised by extreme poverty, poor access to health services, and high rates of HIV/AIDS, their caregiving ability and children's development might be compromised. We aimed to test the effectiveness of a community-based child health and parenting intervention to improve child HIV testing, health, and development in rural Lesotho. METHODS: We implemented a matched cluster-randomised, controlled trial in the Mokhotlong district in northeastern Lesotho with 34 community clusters randomly assigned to intervention or wait-list control groups within a pair. Eligible clusters were villages with non-governmental organisation partner presence and an active preschool. Participants were caregiver-child dyads, where the child was 12-60 months old at baseline. The intervention consisted of eight group sessions delivered at informal preschools to all children in each village. Mobile health events were hosted for all intervention (n=17) and control (n=17) clusters, offering HIV testing and other health services to all community members. Primary outcomes were caregiver-reported child HIV testing, child language development, and child attention. Assessments were done at baseline, immediately post-intervention (3 months post-baseline), and 12 months post-intervention. We assessed child language by means of one caregiver-report measure (MacArthur-Bates Communicative Development Inventory [CDI]) and used two observational assessments of receptive language (the Mullen Scales of Early Learning receptive language subscale, and the Peabody Picture Vocabulary Test 4th edn). Child attention was assessed by means of the Early Childhood Vigilance Task. Assessors were masked to group assignment. Analysis was by intention to treat. This trial was registered with ISRCTN.com, ISRCTN16654287 and is completed. FINDINGS: Between Aug 8, 2015, and Dec 10, 2017, 1040 children (531 intervention; 509 control) and their caregivers were enrolled in 34 clusters (17 intervention; 17 control). Compared with controls, the intervention group reported significantly higher child HIV testing at the 12-month follow-up (relative risk [RR] 1·46, 95% CI 1·29 to 1·65, p<0·0001), but not immediately post-intervention. The intervention group showed significantly higher child receptive language on the caregiver report (CDI) at immediate (effect size 3·79, 95% CI 0·78 to 6·79, p=0·028) but not at 12-month follow-up (effect size 2·96, 95% CI -0·10 to 5·98, p=0·056). There were no significant group differences for the direct assessments of receptive language. Child expressive language and child attention did not differ significantly between groups. INTERPRETATION: Integrated child health and parenting interventions, delivered by trained and supervised lay health workers, can improve both child HIV testing and child development. FUNDING: United States Agency for International Development (USAID) and the President's Emergency Plan for AIDS Relief (PEPFAR).

RESUMEN

BACKGROUND: Newborn screening allows novel treatments for cystic fibrosis (CF) to be trialled in early childhood before irreversible lung injury occurs. As respiratory exacerbations are a potential trial outcome variable, we determined their rate, duration and clinical features in preschool children with CF; and whether they were associated with growth, lung structure and function at age 5 years. METHODS: Respiratory exacerbations were recorded prospectively in Australasian CF Bronchoalveolar Lavage trial subjects from enrolment after newborn screening to age 5 years, when all participants underwent clinical assessment, chest CT scans and spirometry. RESULTS: 168 children (88 boys) experienced 2080 exacerbations, at an average rate of 3.66 exacerbations per person-year; 80.1% were community managed and 19.9% required hospital admission. There was an average increase in exacerbation rate of 9% (95% CI 4% to 14%; p<0.001) per year of age. Exacerbation rate differed by site (p<0.001) and was 26% lower (95% CI 12% to 38%) in children receiving 12 months of prophylactic antibiotics. The rate of exacerbations in the first 2 years was associated with reduced forced expiratory volume in 1 s z scores. Ever having a hospital-managed exacerbation was associated with bronchiectasis (OR 2.67, 95% CI 1.13 to 6.31) in chest CT scans, and lower weight z scores at 5 years of age (coefficient -0.39, 95% CI -0.74 to -0.05). CONCLUSIONS: Respiratory exacerbations in young children are markers for progressive CF lung disease and are potential trial outcome measures for novel treatments in this age group.
