Effects of frequency, intensity, duration and volume of walking interventions on CVD risk factors: a systematic review and meta-regression analysis of randomised controlled trials among inactive healthy adults

ObjectiveWalking interventions in healthy populations show clinically relevant improvements for many cardiovascular disease (CVD) risk factors. We aimed to assess the changes in CVD risk factors and the dose–response relationship between frequency, intensity, duration and volume of walking and cardiovascular risk factors based on randomised controlled trials (RCTs).DesignA systematic review with meta-analysis and meta-regression.Data sourcesFour electronic databases searched from January 1971 to April 2017.Eligibility criteriaWalking RCTs reporting one or more CVD risk factor outcomes; trials including at least one group with walking intervention and a no-walking control group; duration ≥8 weeks; participants ≥18 years old, inactive but healthy; risk factors assessed preintervention and postintervention; English-language articles in peer-reviewed journals.ResultsThirty-seven RCTs, involving 2001 participants (81% women) and assessing 13 CVD risk factors, were identified. Pooled meta-analysis showed favourable effects (P≤0.05) of walking intervention for seven CVD risk factors (body mass, body mass index, body fat, systolic and diastolic blood pressure, fasting glucose and VO2max).There were no significant effects (P&gt;0.05) for waist circumference, waist-to-hip ratio and four blood lipid variables.Despite testing 91 possible dose–response relationships, linear meta-regression analysis adjusted for age indicated just 7 (or 7.7%) statistically significant findings.Summary/conclusionWalking interventions benefit a number of CVD risk factors. Despite multiple studies and tested metrics, only a few dose–response relationships were identified and the possibility of chance findings cannot be ruled out. There is insufficient evidence to quantify the frequency, length, bout duration, intensity and volume of the walking required to improve CVD risk factors.PROSPERO registration numberCRD42016039409.</jats:sec

Interventions outside the workplace for reducing sedentary behaviour in adults under 60

This is a protocol for a Cochrane Review (Intervention). The objectives are as follows: To assess the effects of non-occupational interventions for reducing sedentary behaviour in adults under 60 years of age on sedentary time. Secondary objectives are: to describe other health effects, and adverse events or unintended consequences of the interventions; to determine whether specific components of interventions are associated with changes in sedentary behaviour; to examine if there are any differential effects of interventions based on health inequalities (e.g. age, sex, income, employment)

Walking: the first steps in cardiovascular disease prevention

Health professionals are presented with the challenge of prescribing physical activity that is likely to be sustained by the sedentary majority. Walking is eminently suited to physical activity prescription for inactive individuals as it is accessible to men and women of all age and social groups and poses little risk of injury. This paper reviews recent evidence of the health benefits of walking and promotion of walking behavior

O6-8 Rethinking schools as a setting for physical activity promotion in the 21st Century - A position paper from the Erasmus+ 2PASS 4Health project

Background Schools are ideally placed to provide children and adolescents with multiple opportunities to be or learn to be physically active. However, key reviews have reported that interventions to date have largely failed to have any long-term impact on overall physical activity levels. In this position paper, greater attention to key issues is needed to realise the full potential of schools and ideal physical activity for health promotion setting. Methods This study draws on multi-author expertise to develop a position paper to advance opinion on school-based programmes. Collaborative conceptual thinking was established through various tools such as literature review, evidence synthesis and online and in person meetings. Results/Discussion The adoption of a systems approach is valuable for understanding the complexities of the school setting and to support the implementation of whole-of-school initiatives. Furthermore, we contend that the full range of physical, cognitive, emotional and social benefits that physical activity provides should be considered, rather than a narrow focus solely on physical activity levels. Interdisciplinary research questions are most useful in exploring and evaluating whole-of-school approaches. Informed by process, impact and outcome evaluation and implementation science, both qualitative and quantitative research methodologies and a move beyond traditional research design are needed to advance our knowledge of what works, for whom and in what context. Case studies from several European countries will be presented to illustrate examples of systems approaches in action. This includes examples at multiple levels firstly, a national approach including a Physical Education curriculum reformation (Portugal), a regional approach such as a county council partnership with a University to support physical activity promotion (France) and a local approach at the school level i.e. a whole-of-school physical activity programme (Spain and Ireland). Conclusion From authors expertise and reflection, this paper makes recommendations on the nature of the evidence required to bridge the implementation gap, sustain and scale-up innovative approaches to whole-of-school programmes
