Community-based programmes to prevent falls in children: A systematic review

Objective: We systematically reviewed the literature to examine the evidence for the effectiveness of community-based interventions to reduce fall-related injury in children aged 0-16 years. Methods: We performed a comprehensive search of the literature using the following study selection criteria: community-based intervention study; target population was children aged 0-16 years; outcome measure was fall-related injury rates; and either a community control or historical control was used in the study design. Quality assessment and data abstraction were guided by a standardized procedure and performed independently by two authors. Results: Only six studies fitting the inclusion criteria were identified in our search and only two of these used a trial design with a contemporary community control. Neither of the high quality evaluation studies showed an effect from the intervention and while authors of the remaining studies reported effective falls prevention programmes, the pre- and post-intervention design, uncontrolled for background secular trends, makes causal inferences from these studies difficult. Conclusion: There is a paucity of research studies from which evidence regarding the effectiveness of community-based intervention programmes for the prevention of fall-related injury in children could be based.

The importance of being physical in the middle years

Young people are physical (as are adults) and their bodies are significant in relation to who they are, what and how they learn, and who they can become. Consistent with middle schooling philosophy, but often not reflected in practice, a balanced approach to all aspects of the growth and development of young people is supported. Much research has shown the middle years is an important time assigned to 'identity development' and 'physical development' while it is also a time when many young people become less physically active and less engaged in learning at school. This paper reviews current research about physical activity, physical education and physicality in order to locate the place of the physical in the lives of young people and encourage practices in the middle years that acknowledge this physicality.

Change in physiotherapy management of children with cystic fibrosis in a large urban hospital

A retrospective audit was conducted in 1998 and 2000 to review the physiotherapy management of hospitalized children with cystic fibrosis (CF) at the Brisbane Royal Children's Hospital (RCH). The objective was to detect and explore possible changes in patient management in this time period and investigate whether these changes reflected changes in the current theory of CF management. All children over two years of age with CF admitted during 1998 and 2000 with pulmonary manifestation and who satisfied set criteria were included (n = 249). Relative frequency of each of six treatment modalities used were examined on two occasions, revealing some degree of change in practice reflecting the changes in current theory. There was a significant decrease in the frequency of usage of postural drainage with head-down tilt (p < 0.001), and autogenic drainage (p < 0.001) between 1998 and 2000. Modified postural drainage without head-down tilt (p < 0.001), and positive expiratory pressure devices (p < 0.001) were used more frequently in 2000 (p < 0.001). No significant changes were identified in the use of Flutter VRP1 (p = 0.145) and exercise (p = 0.763). No significant differences were found in population demographics or occurrence of concomitant factors that may influence patient management.

Socioeconomic position, cognitive function, and clustering of cardiovascular risk factors in adolescence: Findings from the Mater University Study of Pregnancy and its outcomes

Objectives: The objectives of this study were to examine the extent of clustering of smoking, high levels of television watching, overweight, and high blood pressure among adolescents and whether this clustering varies by socioeconomic position and Cognitive function. Methods: This study was a cross-sectional analysis of 3613 (1742 females) participants of an Australian birth cohort who were examined at age 14. Results: Three hundred fifty-three (9.8%) of the participants had co-occurrence of three or four risk factors. Risk factors clustered in these adolescents with a greater number of participants than would be predicted by assumptions of independence having no risk factors and three or four risk factors. The extent of clustering tended to be greater in those from lower-income families and among those with lower cognitive function. The age-adjusted ratio of observed to expected cooccurrence of three or four risk factors was 2.70 (95% confidence interval [Cl], 1.80-4.06) among those from low-income families and 1.70 (95% Cl, 1.34-2.16) among those from more affluent families. The ratio among those with low Raven's scores (nonverbal reasoning) was 2.36 (95% Cl, 1.69-3.30) and among those with higher scores was 1.51 (95% Cl, 1.19-1.92); similar results for the WRAT 3 score (reading ability) were 2.69 (95% Cl, 1.85-3.94) and 1.68 (95% Cl, 1.34-2.11). Clustering did not differ by sex. Conclusion: Among adolescents, coronary heart disease risk factors cluster, and there is some evidence that this clustering is greater among those from families with low income and those who have lower cognitive function.

Pulse transit time changes observed with different limb positions

Pulse transit time (PTT) is a non-invasive measure of arterial compliance. It can be used to assess instantaneous blood pressure (BP) changes in continual cardiovascular measurement such as during overnight respiratory sleep studies. In these studies, periodic changes in limb position can occur randomly. However, little is known about their possible effects on PTT monitored on the various limbs. The objective of this study was to evaluate PTT differences on all four limbs during two positional changes (lowering and raising of a limb). Ten healthy adults (seven male) with a mean age of 27.0 years were recruited in this study. The results showed that the limb that underwent a positional change had significant (p < 0.05) local PTT differences when compared to its nominal baseline value, whereas PTT changes in the other remaining limbs were insignificant (p > 0.05). The mean PTT value measured from a vertically-raised limb increased by 42.7 ms, while it decreased by 28.1 ms with a half-lowered limb. The PTT differences observed during positional change can be contributed to by the complex interactions between hydrostatic pressure changes, autonomic and local autoregulation experienced in these limbs. Hence the findings herein suggest that PTT is able to reflect local circulatory responses despite changes in the position of other limbs. This can be useful in prolonged clinical observations where limb movements are expected.

Attention deficit disorder: not just for children

Attention deficit/hyperactivity disorder (ADHD) has long been described in children who demonstrate developmentally inappropriate symptoms of inattention, impulsivity and motor restlessness. In adults, symptoms are known to persist and the validity of adult ADHD as an entity is now recognized. There is an associated high proportion of other serious psychiatric comorbidities, especially substance abuse, mood and anxiety disorders. Advances have been made into the aetiology and management of ADHD. Many of these focus on the dopamine and noradrenaline pathways.

Common causes of sleep disruption and daytime sleepiness: childhood sleep disorders II

There are strong associations between childhood sleep disorders and behavioural, concentration and mood problems. Sleep disorders caused and maintained by behavioural factors (eg, sleep-onset association disorder) are common in young children, and have a significant impact on families. Evaluation should include a medical history, a physical, neurological and developmental examination, a description of any nocturnal events or daytime effects of the child's disturbed sleep, and a good understanding of the family situation and parental management of the child. Management involves recognising the developmental age of the child and the family dynamics, and educating and supporting families in applying behavioural techniques to establish good sleep hygiene. Children with parasomnias (eg, night terrors) also benefit from good sleep hygiene, while those with respiratory or neurological causes of sleep disturbance should be referred for specialist treatment.
