INTRODUCTION activity intervention on weight-related outcomes. The approaches included intensive classroom physical activity lessons led by trained teachers, moderate to vigorous physical activity sessions, nutrition and education materials, and promoting and providing a healthy diet. There was weak evidence that these approaches were effective at reducing body mass index (BMI), BMI standard deviation score (SDS), prevalence of obesity and overweight, percentage body fat, waist circumference and skinfold thickness. Intervention studies that reported a significant effect tended to be of long duration (between 52 and 156 weeks), with the longer-term programmes having the greatest effect. A further 28 studies were school-based with a home component (e. These studies provided moderate evidence of effectiveness, with half reporting statistically significant beneficial intervention effects. However, in all studies, a range of adiposity measures was used and there was high study heterogeneity in terms of setting, design, sample size, characteristics, intervention approach and length of follow-up, which makes cross-comparisons challenging. The review was unable to identify specific programme characteristics and approaches predictive of success or to explore the comparative effectiveness of specific intervention approaches (e. Since the publication of the above reviews, a number of additional evaluations of school-based 13–16 interventions have been published involving children of a similar age to those in the Health Lifestyles Programme (HeLP) study. However, evidence of effectiveness in changing behaviours and/or weight status of children continues to be inconsistent and the content of the intervention varies greatly between studies. In 2010, The Healthy Study Group13 published its findings from a 3-year cluster randomised controlled trial (RCT) of a multicomponent programme addressing risk factors for diabetes among American children whose race or ethnic group and socioeconomic status placed them at high risk of obesity and type 2 diabetes mellitus (T2DM). The intervention consisted of four integrated components: (1) nutrition, (2) physical activity, (3) behavioural knowledge and skills, and (4) communications and social marketing. No significant group differences were observed in the prevalence of overweight and obesity (primary outcome), but children in the intervention schools had a greater reduction in the secondary outcome of BMI SDS (–0. This was a multicomponent programme based on behavioural and ecological models, involving physical education sessions delivered by a specialist physical education teacher, additional sport and play activities outside school hours, and an educational programme. Significant positive intervention effects were found in terms of the percentage of overweight children, waist circumference and 20-minute shuttle run among those aged 6–9 years. The prevalence of overweight in 6 to 8-year-olds increased by 4. No significant effects were found for BMI for 9- to 12-year-olds. In 2014, the results of the Active for Life-year 5 (AFLY5)16 study, a UK primary school-based cluster RCT aimed at increasing physical activity, reducing sedentary behaviours and increasing fruit and vegetable consumption in 9- to 10-year-old children, were published. No differences were observed between the intervention and control groups in the three primary outcomes outlined above. The intervention was effective for three out of nine secondary outcomes after multiple testing was taken into account: self-reported time spent in screen viewing at the weekend, self-reported servings of snacks per day and servings of high-energy drinks per day were all reduced. The intervention was an adaptation of the American school-based intervention Planet Health,17 consisting of 16 lessons (delivered by the class teacher) and 10 pieces of homework in which the children were encouraged to work with their parents. The intervention took a multilevel approach including collaboration with school principals and teachers, school health services and parent committees. There was no significant effect of the intervention overall, although significant effects were found for both BMI (p = 0. Furthermore, children of higher-educated parents seemed to benefit more from the intervention, highlighting the need to develop interventions that do not widen the health inequalities that already exist between children from different socioeconomic groups. Rationale for HeLP We began work to design, pilot and then fully evaluate a school-based obesity prevention programme in primary schools in 2006. We therefore searched the literature for appropriate systematic reviews of school-based obesity prevention programmes and carried out extensive stakeholder consultation with practitioners (teachers, head teachers and drama specialists), local policy-makers (director of public health and the public health policy lead), public health commissioners and the local healthy schools team, in order to understand the school, education and public health context at that time. The overarching aim of the research was to develop a school-based intervention, assess its feasibility and complete pilot work before we sought funding to run the full-scale effectiveness trial, were that deemed appropriate. Their conclusions were that a combined approach was likely to be more effective in preventing children becoming overweight in the long term. We wanted to incorporate these recommendations into our programme and address the methodological limitations reported in other trials, such as insufficient statistical power; biased recruitment from, and retention of, more affluent schools, children and families; short follow-up periods; and high levels of attrition.

In brain tissue (but not elsewhere) buy naprosyn 500mg low cost arthritis relief cream reviews, UBE3A buy discount naprosyn 500 mg on line arthritis in club feet, the AS gene, is expressed predominantly from the The association of autism with the fragile X syndrome (FXS) was first suggested nearly 20 years ago (87,88). Disrupted expression of the mater- X phenotype is frequently characterized by behaviors that nal UBE3A, therefore, produces AS, whereas disruption of can resemble the core symptom domains of autism such as the paternally derived allele produces no discernible abnor- language abnormalities, decreased nonverbal communica- mal phenotype (73). PWS genes, conversely, are paternally tion, social isolation, and repetitive motor behaviors such expressed; the predominant cause of PWS, therefore, is dis- as rocking and hand biting (89). In support of this associa- rupted expression of the paternal copy of the small nuclear tion, early chromosomal investigations reported a rate of ribonucleoprotein polypeptide N (SNRPN)gene and other the fragile X mutation [fra(X)(q27. Another recently identified element proached 20% (31,90). These segments of RNA are oppositely of the link between these two disorders. UBE3A, for example, has an antisense tran- 4% (91–93), similar to the rate of fragile X in the general script that is expressed solely from the paternally derived MR population (94). This antisense transcript may play a role in the types of chromosomal abnormalities in autism, though not suppression of the nonexpressed allele, and mutations in necessarily disproportionately so. Likewise, there are subtle this transcript, therefore, could contribute to some cases of but significant differences between the behavioral pheno- AS (76). Thus, just as imprinting plays a pivotal role in types of the two disorders. Autism is characterized by social PWS and AS, it is likely to significantly influence the effect indifference and deficits in the perception of emotion, of 15q11-q13 abnormalities in autism as well. Duplications of large genomic segments are asso- by a trinucleotide repeat that expands as it is transmitted ciated with chromosomal abnormalities in a number of spe- to successive generations (96).

In the visual modality, for example, the early which occurs because the initial S1 automatically activates C1 component (onset latency 50 to 60 msec) originates an inhibitory system that suppresses responsiveness to S2 (9, in retinotopically organized visual cortex (5) and varies in 10). This inhibitory system presumably prevents irrelevant amplitude according to the spatial frequency of the stimulus information from ascending to higher levels of cortical pro- (6).
