Literature Review - Health behaviour change models and approaches for families and young people to support HEAT 3: Child Healthy Weight Programmes

The literature review has been commissioned by NHS Health Scotland to review the health behaviour change models and approaches for families, children and young people to support the development and delivery of effective child healthy weight programmes. Despite the consistent recommendations from NICE and SIGN for the inclusion of behavioural components in child healthy weight programmes, there is little information on effectiveness of specific techniques and which to incorporate. The aim was therefore to provide information on which specific behavioural treatment components, behaviour change models and approaches should underpin clinical guidelines and childhood obesity treatment programmes. Secondly, in light of recommendations for programmes to be delivered by appropriately trained professionals, the review aimed to identify the skills and competencies required and resources and training available for effective delivery of the behavioural components. The outcomes of the literature review will be applied in enhancing the guidance for practitioners involved in the development and delivery of effective child healthy weight programmes; and thereby support achievement of the Scottish Government’s HEAT 3 target aimed at monitoring the attendance and completion of approved ’child healthy weight intervention programmes’. The report includes the background, aims, and objectives, sets out the scope of the review, presents a brief description of the methods and main findings. The methods and stakeholder views are then presented followed by a discussion of the implications for applying the evidence in practice and further research recommendations

Scientists must act on our own warnings to humanity

We face interconnected planetary emergencies threatening our climate and ecosystems. Charlie J. Gardner and Claire F. R. Wordley argue that scientists should join civil disobedience movements to fight these unprecedented crises

Air pollution and the incidence of ischaemic and haemorrhagic stroke in the South London Stroke Register: a case-cross-over analysis.

BACKGROUND: Few European studies investigating associations between short-term exposure to air pollution and incident stroke have considered stroke subtypes. Using information from the South London Stroke Register for 2005-2012, we investigated associations between daily concentrations of gaseous and particulate air pollutants and incident stroke subtypes in an ethnically diverse area of London, UK. METHODS: Modelled daily pollutant concentrations based on a combination of measurements and dispersion modelling were linked at postcode level to incident stroke events stratified by haemorrhagic and ischaemic subtypes. The data were analysed using a time-stratified case-cross-over approach. Conditional logistic regression models included natural cubic splines for daily mean temperature and daily mean relative humidity, a binary term for public holidays and a sine-cosine annual cycle. Of primary interest were same day mean concentrations of particulate matter <2.5 and <10 µm in diameter (PM2.5, PM10), ozone (O3), nitrogen dioxide (NO2) and NO2+nitrogen oxide (NOX). RESULTS: Our analysis was based on 1758 incident strokes (1311 were ischaemic and 256 were haemorrhagic). We found no evidence of an association between all stroke or ischaemic stroke and same day exposure to PM2.5, PM10, O3, NO2 or NOX. For haemorrhagic stroke, we found a negative association with PM10 suggestive of a 14.6% (95% CI 0.7% to 26.5%) fall in risk per 10 µg/m(3) increase in pollutant. CONCLUSIONS: Using data from the South London Stroke Register, we found no evidence of a positive association between outdoor air pollution and incident stroke or its subtypes. These results, though in contrast to recent meta-analyses, are not inconsistent with the mixed findings of other UK studies

Worldwide insect declines: An important message, but interpret with caution.

A recent paper claiming evidence of global insect declines achieved huge media attention, including claims of "insectaggedon" and a "collapse of nature." Here, we argue that while many insects are declining in many places around the world, the study has important limitations that should be highlighted. We emphasise the robust evidence of large and rapid insect declines present in the literature, while also highlighting the limitations of the original study

Evidence complacency hampers conservation.

The pernicious problem of evidence complacency, illustrated here through conservation policy and practice, results in poor practice and inefficiencies. It also increases our vulnerability to a ‘post-truth’ world dealing with ‘alternative facts’

Aerodynamic Characterisation of a Compact Car Overtaking a Heavy Vehicle

The time-varying flow field a compact car experiences whilst performing an overtaking manoeuvre of a heavy vehicle has been characterized using an array of five, five-hole dynamic pressure probes mounted in front of an operational, full-scale compact automotive vehicle. In addition, the effect of these conditions on the vehicle’s surface pressure has been investigated through 188 pressure taps distributed over the compact vehicle in separate experiments. The experiments were performed in ideal conditions, on a 2.9 km runway of the Fassberg airfield next to DLR Trauen, Germany

Evidence-based synopsis of interventions, a new tool in primate conservation and research

Biodiversity conservation is often described as a crisis discipline, with conservationists rushing from one emergency to the next. This frequently leaves limited resources available to evaluate the effectiveness of the conservation interventions that have been implemented. Furthermore, for those seeking out scientific evidence for conservation decisions, much is locked behind subscription-only access or hidden in jargon-heavy literature. Assessing the effectiveness of conservation interventions, and making the results readily available to practitioners, could transform conservation efforts.We are grateful to the funders of the Primate Synopsis work, Robert Bosch Stiftung at Max Planck Institute for Evolutionary Anthropology in Germany and Arcadia for the Conservation Evidence work at the University of Cambridge
