Hospitalizations for unintentional injuries among Canadian adults in areas with a high percentage of Aboriginal-identity residents.

INTRODUCTION: Injuries are a leading cause of death and morbidity. While individual Aboriginal identifiers are not routinely available on national administrative databases, this study examines unintentional injury hospitalization, by cause, in areas with a high percentage of Aboriginal-identity residents. METHODS: Age-standardized hospitalization rates (ASHRs) and rate ratios were calculated based on 2004/2005-2009/2010 data from the Discharge Abstract Database. RESULTS: Falls were the most frequent cause of injury. For both sexes, ASHRs were highest in high-percentage First Nations-identity areas; high-percentage Métis-identity areas presented the highest overall ASHR among men aged 20-29 years, and high-percentage Inuit-identity areas presented the lowest ASHRs among men of all age groups. Some causes, such as falls, presented a high ASHR but a rate ratio similar to that for all causes combined; other causes, such as firearm injuries among men in high-percentage First Nations-identity areas, presented a relatively low ASHR but a high rate ratio. Residents of high-percentage Aboriginal-identity areas have a higher ASHR for hospitalization for injuries than residents of low-percentage Aboriginal-identity areas. CONCLUSION: Residents of high-percentage Aboriginal-identity areas also live in areas of lower socio-economic conditions, suggesting that the causes for rate differences among areas require further investigation.

TITRE: Hospitalisations pour blessures non intentionnelles chez les adultes au Canada, dans les régions ayant un fort pourcentage de résidents d'identité autochtone. INTRODUCTION: Les blessures constituent une cause importante de décès et de morbidité. Bien qu'aucun indicateur d'identité autochtone ne soit directement disponible dans les bases de données administratives nationales, cette étude porte sur les hospitalisations pour blessure non intentionnelle, selon la cause, dans les régions ayant un fort pourcentage de résidents d'identité autochtone. MÉTHODOLOGIE: Nous avons calculé les taux d'hospitalisation normalisés selon l'âge (THNA) et les rapports de taux pour 2004-2005 à 2009-2010, à partir de la Base de données sur les congés des patients. RÉSULTATS: Les chutes étaient la cause principale de blessure. Les THNA étaient plus élevés pour les hommes comme pour les femmes dans les régions ayant un fort pourcentage de membres des Premières nations; dans les régions ayant un fort pourcentage de Métis, c'est chez les hommes de 20 à 29 ans que le THNA global était le plus élevé, tandis qu'il était le plus bas chez les hommes de tous les groupes d'âge dans les régions à fort pourcentage d'Inuits. Certaines causes, telles que les chutes, étaient associées à un THNA élevé mais avec un rapport de taux semblable à celui observé pour toutes causes confondues; d'autres causes, comme les blessures par arme à feu chez les hommes dans les régions à fort pourcentage de membres des Premières nations, présentaient un THNA relativement faible mais un rapport de taux élevé. Les résidents des régions à fort pourcentage d'Autochtones présentaient un THNA pour blessure plus élevé que ceux des régions à faible pourcentage d'Autochtones. CONCLUSION: Les résidents des régions à fort pourcentage d'Autochtones vivent dans des régions dont le statut socioéconomique était faible, ce qui invite à une recherche plus approfondie à propos des différences de taux entre régions.

Parenting children with neurodevelopmental disorders and/or behaviour problems.

BACKGROUND: Parenting behaviours influence child well-being and development. However, much of the research on parenting behaviours and their correlates has focused on caregivers of healthy, typically developing children. Relatively less is known about the parenting behaviours of caregivers of children with chronic health conditions. OBJECTIVE: To examine and compare three parenting behaviours (positive interactions, consistency and ineffective parenting) among caregivers of children with neurodevelopmental disorders and/or externalizing behaviour problems, before and after accounting for child and family socio-demographic characteristics. METHODS: Participants (n= 14 226) were drawn from the National Longitudinal Survey of Children and Youth, a long-term study of Canadian children that follows their development and well-being from birth to early adulthood. Children (and their caregivers) were divided into four groups according to the presence of a neurodevelopmental disorder (NDD; n= 815), the presence of an externalizing behaviour problem (EBP; n= 1322), the presence of both conditions (BOTH; n= 452) or neither of these conditions (NEITHER; n= 11 376). RESULTS: Caregivers of children in the NEITHER group reported significantly higher positive interaction scores and lower ineffective parenting behaviours than caregivers of children in any of the other three groups. Caregivers of children in the EBP and BOTH groups reported similar levels of consistency, but significantly lower levels than caregivers of NDD or NEITHER children. These associations largely remained after accounting for child and family socio-demographic characteristics, with two exceptions: caregivers' reports of positive interactions were no longer significantly associated with child's NDD and BOTH conditions. CONCLUSIONS: Parenting children with multiple health conditions can be associated with less positive, less consistent and more ineffective parenting behaviours. Understanding the factors that are associated with the challenges of caring for these children may require additional research attention.

Contextual influences of parenting behaviors for children with neurodevelopmental disorders: results from a Canadian national survey.

PURPOSE: This population-based study examined correlates of three parenting behaviors (positive interactions, consistency, and ineffective parenting) that have been shown to differ in children with neurodevelopmental disorders (NDDs), with and without externalizing behavior problems (EBPs), as compared to children with neither condition. METHOD: The sample of children aged 4-11 (N = 14,226) was drawn from the Canadian National Longitudinal Survey of Children and Youth (NLSCY). Analyses examined the associations of child, parental, and social context factors with parenting behaviors, and whether they differed by child health group. RESULTS: Child age, family functioning, and social support variables were significant predictors of all three parenting behaviors. Significant interaction effects highlight the importance of the child's sex, birth order, and support received from community or social service professionals, and that these factors have differential impacts on parenting behaviors depending on the child's health group. CONCLUSIONS: Other Child, parent, and social context factors are associated with parenting behaviors but these associations vary by the child's health group. Parenting behaviors differ for children with NDDs with and without EBPs. These findings offer important implications for practice and research and point to the importance of considering multiple contexts of influence, as well as their interactions, in understanding differences in parenting behaviors.

Modeling interinformant agreement in the absence of a "gold standard".

Epidemiological surveys of child and adolescent mental disorders often rely on multiple informants to get a complete diagnostic picture. A consistent finding in the literature is that different informants often do not identify the same children as being disordered. However, because current strategies for estimating interinformant agreement often involve categorizing children using less than perfectly sensitive and/or specific symptoms, biased estimates of interinformant agreement are likely. The aim of this report was to illustrate how latent class analysis (LCA) can be used to model interinformant agreement in the absence of a "gold standard". The proposed model consists of informant-specific latent variables each made up of two or more latent classes corresponding to different levels of symptomatology. Unlike most previous applications of LCA this model allows us to model the extent to which the prevalence of the disorder is the same across informants; and, in addition, the association between informants. The data set comes from a prospective longitudinal study of 2,264 children from Quebec (1,155 boys and 1,109 girls). In grade 2, teachers and mothers independently rated each child on three physical aggression behavior symptoms. We satisfactorily accounted for the cross-classification of the behavior symptoms by postulating the existence of two latent variables--one for each informant each made up of three latent classes of children: low-, medium-, and high-aggressive. The results showed that the prevalence of low- and medium-aggressive children in the population differed from teacher to mother, but that the prevalence of high-aggressive children did not. We found that the association between teacher and mother was large and positive and did not vary according to the child's physical aggression state or gender; in contrast, the association between physical aggression and gender was not the same for mother and teacher. Limitations and other potential applications of the proposed model are discussed.

Maternal reports of child injuries in Canada: trends and patterns by age and gender.

OBJECTIVES: This study examines gender and age differences in maternal reports of injuries in a cross sectional group of children aged 0-11 years. The cause, nature, body part injured, and location of injury are explored, as are the associations with family socioeconomic indicators and associations with limitations in activities. METHODS: Data for 22831 children and their families come from cycle 1 of the Canadian National Longitudinal Survey of Children and Youth collected in 1995. Descriptive analyses and chi2 tests for trends are used to examine injury variations by child gender and age. Logistic regressions are used to examine the relationship between socioeconomic indicators and injury and the associations between injury and limitations in activities. RESULTS: Consistent with findings from hospital data, boys experience more injuries than girls, and injuries increase with child age. Falls are the most common sources of maternally reported injuries, followed by scalds/poisonings for young children and sports injuries for school aged children. The majority of injuries occur in or around the home for young children, but at school for older children. For maternal reports of childhood injuries, single marital status is a risk factor for boys. CONCLUSIONS: Maternally reported injuries occur in 10% of Canadian children and many of these are associated with limitations in activities. Preventative strategies should take both child age and gender into consideration.

Concordance of maternal and teacher ratings of school and behavior problems in children of varying birth weights.

To examine the concordance of mother and teacher ratings of children born at different birth weights on measures of school functioning, behavioral problems, and social competencies, we used a prospective cohort study involving children in two previously studied multisite birth cohorts whom we recontacted at 8 to 10 years of age. This provided a multisite sample of 784 low birth weight children and 334 normal birth weight children. Teacher reports of children's behaviors were obtained from 80% of the 1400 teachers contacted. We found that birth weight and neonatal health were associated with both maternal and teacher reports; that maternal characteristics, e.g., low levels of education and poor mental health, were associated with the greatest discrepancies in reports; and that although mothers' reports of objective measures were accurate, their assessments of behavioral problems and social competence often differed from those of teachers.
