Despite its importance as a key parameter of child health and development, growth velocity is difficult to determine in real time because skeletal growth is slow and clinical tools to accurately detect very small increments of growth do not exist. We report discovery of a marker for skeletal growth in infants and children. The intact trimeric noncollagenous 1 (NC1) domain of type X collagen, the marker we designated as CXM for Collagen X Marker, is a degradation by-product of endochondral ossification that is released into the circulation in proportion to overall growth plate activity...

Parental engagement in positive activities with the child may show significant variation across time, assuming a crucial influence on child development. In dual-earner families, work-family conflict can interfere with parental engagement, with negative consequences for children's behavior. The current study examined the change trajectories of mothers' and fathers' engagement in early childhood, analyzing whether these trajectories are influenced by parents' work-family conflict and whether they predict child behavioral self-control...

Research shows that childhood dysregulation is associated with later psychiatric disorders. It does not yet resolve discrepancies in the operationalization of dysregulation. It is also far from settled on the origins and implications of individual differences in dysregulation. This study tested several operational definitions of dysregulation using Achenbach attention, anxious/depressed, and aggression subscales. Individual growth curves of dysregulation were computed, and predictors of growth differences were considered...

Associations between marital intimate partner violence (IPV) and postseparation coparenting relationship trajectories were examined among 135 mothers who participated in 5 interviews at 3-month intervals in the year following their divorce filing. Growth curve analysis was conducted to assess change and variability in coparenting dimensions (i.e., conflict, support, communication about child rearing, and harassment) in the overall sample and by type of IPV. In the overall sample, coparenting conflict, communication about child rearing, and harassment decreased across the year following separation...

OBJECTIVES: Population-specific growth references are important in understanding local growth variation, especially in developing countries where child growth is poor and the need for effective health interventions is high. In this article, we use mixed longitudinal data to calculate the first growth curves for rural East Timorese children to identify where, during development, deviation from the international standards occurs. MATERIALS AND METHODS: Over an eight-year period, 1,245 children from two ecologically distinct rural areas of Timor-Leste were measured a total of 4,904 times...

A large proportion of children experience subclinical levels of anxiety and cognitive-behavioral therapy (CBT) aimed at preventing anxiety disorders is moderately effective. However, most at-risk children do not seek help or drop out of programs prematurely because of stigma, lack of motivation, and accessibility barriers. Applied games have received increased attention as viable alternatives and have shown promising results, but direct comparisons between applied games and the gold-standard CBT are lacking...

Few longitudinal studies have analyzed how violence exposure (e.g. child maltreatment, witnessing community violence) influence both externalizing and Post-Traumatic Stress (PTS) symptoms among children in foster care. Data from three waves of the National Survey of Child and Adolescent Well-Being (1999-2007) (NSCAW; National Data Archive on Child Abuse and Neglect, 2002) were analyzed to investigate the change trajectories of both externalizing and PTS symptomatology among children with a substantiated report of child maltreatment by Child Protective Services (CPS) between October 1999 and December 2000...

RATIONALE: Externalizing behavior problems are common among children and adolescents, and have considerable negative impacts on their long-term health and wellbeing. Substantial evidence supports a link between neighborhood conditions and externalizing behaviors. However, the timing of neighborhood effects on the developmental course of externalizing behaviors and the role of family and peer processes in shaping neighborhood effects remains unclear. OBJECTIVE: The current study aims to examine the relationship between perceived neighborhood quality and trajectories of child externalizing behaviors in a U...

Objectives Japanese and South Koreans have traditionally been shorter than Europeans, but have recently become appreciably taller. The aim was to quantify the secular trend patterns in height and weight growth in the two countries over 50 years using the SITAR growth curve model. Methods Data on mean height and weight by sex in 1-year age groups from 1 to 20 years were obtained by decade in South Korea (1965-2005) and Japan (1950-2010). The data were analyzed using SITAR (SuperImposition by Translation And Rotation), which estimates a mean curve and three adjustments-size, timing and intensity-reflecting how the individual surveys differ from the mean...

BACKGROUND: Data on the growth of diabetic children is conflicting. The aim of this study was to create and validate acceptable body mass index (BMI)-standardized percentiles and curves applied to Egyptian prepubescent diabetic children. METHODS: The cross-sectional study comprised 822 prepubescent children with type 1 diabetes mellitus (T1DM), whose ages ranged from 3 years to 10 years±6 months. An anthropometric assessment for each child was performed: body weight, height and BMI were calculated (weight [kg]/height [m2]), and glycated hemoglobin levels were determined...

BACKGROUND: Infant feeding practices are a focus of early obesity prevention. We tested whether infant growth velocity increased after breastfeeding termination and complementary food introduction. METHODS: Our secondary analysis included a sample of 547 mother-infant dyads from a longitudinal randomized controlled trial conducted in Michigan and Colorado. Infant anthropometrics at birth, baseline, and 6- and 12-month follow-up were standardized to BMI-for-age z-score (ZBMI) according to World Health Organization (WHO) growth charts...

This study examined teacher-child conflict as a possible mediator of the effects of temperamental anger and effortful control on subsequent externalizing behavior. Reciprocal influences between teacher-child conflict and externalizing behavior were also examined. Participants were 1,152 children (49% female; 81.6% non-Hispanic White) from the Study of Early Child Care and Youth Development. Multivariate growth curve modeling revealed that greater effortful control at age 54 months indirectly predicted lower levels of, and subsequent changes in, externalizing behavior from kindergarten to Grade 6 through reduced teacher-child conflict...

PURPOSE: Youth physical activity (PA) levels differ by race/ethnicity and socioeconomic status (SES). It is well established that various multilevel factors may influence changes in PA. The present study examined whether the association between the change in individual, interpersonal, and environmental factors and the change in PA is modified by race/ethnicity or SES. METHODS: This study followed 643 youths and their parents from suburban and rural South Carolina participating in the Transitions and Activity Changes in Kids (TRACK) Study in 2008-2009 and 2010-2011...

BACKGROUND: Maternal and child undernutrition is an important issue, particularly in low- and middle-income countries. Children at high risk of malnutrition should be prioritized to receive necessary interventions to minimize such risk. Several risk factors have been proposed; however, until now, there has been no appropriate evaluation method to identify these children. In sub-Saharan Africa, children commonly receive regular check-ups from community health workers. A simple and easy nutrition assessment method is therefore needed for use by semi-professional health workers...
