Natural history of mental health competence from childhood to adolescence.

BACKGROUND: Mental health competence (MHC) involves psychosocial capabilities such as regulating emotions, interacting well with peers and caring for others, and predicts a range of health and social outcomes. This study examines the course of MHC from childhood to adolescence and patterning by gender and disadvantage, in Australian and UK contexts. METHODS: Data: Longitudinal Study of Australian Children (n=4983) and the Millennium Cohort Study (n=18 296). Measures: A measure capturing key aspects of MHC was derived summing items from the parent-reported Strengths and Difficulties Questionnaire, assessed at 4-5 years, 6-7 years, 10-11 years and 14-15 years. Analysis: Proportions of children with high MHC (scores ≥23 of range 8-24) were estimated by age and country. Random-effects models were used to define MHC trajectories according to baseline MHC and change over time. Sociodemographic patterns were described. RESULTS: The prevalence of high MHC steadily increased from 4 years to 15 years (from 13.6% to 15.8% and 20.6% to 26.2% in Australia and the UK, respectively). Examination of trajectories revealed that pathways of some children diverge from this normative MHC progression. For example, 7% and 9% of children in Australia and the UK, respectively, had a low starting point and decreased further in MHC by mid-adolescence. At all ages, and over time, MHC was lower for boys compared with girls and for children from disadvantaged compared with advantaged family backgrounds. CONCLUSIONS: Approaches to promoting MHC require a sustained focus from the early years through to adolescence, with more intensive approaches likely needed to support disadvantaged groups and boys.

Sleep problems in the first year of elementary school: The role of sleep hygiene, gender and socioeconomic status.

OBJECTIVES: To determine (1) the relationship between sleep hygiene practices and parent-reported child sleep problems in students in the first year of elementary school, (2) whether the relationship differed by (a) gender and (b) SES and (3) in a multivariate explanatory model. DESIGN: Cross-sectional survey of a population-based sample. SETTING: Forty-five elementary schools in metropolitan Melbourne, Australia. PARTICIPANTS: Families of children aged 4-6 years in the first year of elementary school in Melbourne, Australia. MEASUREMENTS: Exposures: Parent-reported child sleep hygiene, gender and data linkage to community-based disadvantage. OUTCOME: Parent-reported child sleep problems. ANALYSES: Logistic regression models were used to examine each aim. RESULTS: Of 6635 approached parents, 4901 (74.30%) participated. In the final model, using audio devices at bedtime was associated with increased risk of child sleep problems (OR 2.12, 95% CI 1.60, 2.81) as was an inconsistent bedtime routine on school nights (OR 2.52, 95% CI 1.76, 3.60) and non-school nights (OR 1.66, 95% CI 1.09, 2.55). Boys with an inconsistent bedtime routine on non-school nights had a higher risk (OR 2.07, 95% 1.49, 2.88) than girls (OR 1.61, 95% CI 1.15, 2.28). SES was not associated with sleep problems. CONCLUSION: Inconsistent bedtime routines and audio device use were each associated with an increased risk of parent-reported sleep problems. Associations did not differ based on SES but did for boys and girls in terms of inconsistent bedtimes on weekends. Behavioral sleep interventions targeting sleep hygiene could have similar benefits for all children, regardless of socio-economic status.

The quality of reporting in cluster randomised crossover trials: proposal for reporting items and an assessment of reporting quality.

BACKGROUND: The cluster randomised crossover (CRXO) design is gaining popularity in trial settings where individual randomisation or parallel group cluster randomisation is not feasible or practical. Our aim is to stimulate discussion on the content of a reporting guideline for CRXO trials and to assess the reporting quality of published CRXO trials. METHODS: We undertook a systematic review of CRXO trials. Searches of MEDLINE, EMBASE, and CINAHL Plus as well as citation searches of CRXO methodological articles were conducted to December 2014. Reporting quality was assessed against both modified items from 2010 CONSORT and 2012 cluster trials extension and other proposed quality measures. RESULTS: Of the 3425 records identified through database searching, 83 trials met the inclusion criteria. Trials were infrequently identified as "cluster randomis(z)ed crossover" in title (n = 7, 8%) or abstract (n = 21, 25%), and a rationale for the design was infrequently provided (n = 20, 24%). Design parameters such as the number of clusters and number of periods were well reported. Discussion of carryover took place in only 17 trials (20%). Sample size methods were only reported in 58% (n = 48) of trials. A range of approaches were used to report baseline characteristics. The analysis method was not adequately reported in 23% (n = 19) of trials. The observed within-cluster within-period intracluster correlation and within-cluster between-period intracluster correlation for the primary outcome data were not reported in any trial. The potential for selection, performance, and detection bias could be evaluated in 30%, 81%, and 70% of trials, respectively. CONCLUSIONS: There is a clear need to improve the quality of reporting in CRXO trials. Given the unique features of a CRXO trial, it is important to develop a CONSORT extension. Consensus amongst trialists on the content of such a guideline is essential.
