Can the London 2012 Olympics 'inspire a generation' to do more physical or sporting activities? An overview of systematic reviews

Effect of Elite Sport on Physical Activity Practice in the General Population: A Systematic Review

BACKGROUND

Our study investigated the effect of elite sport on physical activity (PA) practice in the general population.

METHODS

Structured Boolean searches were conducted across 5 electronic databases (PubMed, JSTOR, Web of Science, SPORTDiscus, and PsycInfo) from January 2000 to August 2021. Peer-reviewed studies in English were included if the effects of hosting elite sport events, elite sport success, and elite sport role modeling on PA/sport practice in the general population were measured.

RESULTS

We identified 12,563 articles and included 36 articles. Most studies investigated the effect of hosting elite sport events (n = 27), followed by elite sport success (n = 16) and elite sport role modeling (n = 3). Most studies did not observe a positive effect of hosting elite sport events, elite sport success, or elite sport role modeling on PA/sport practice in the general population. No evidence of a lagged effect of elite sport was observed. No evidence of elite sport effects was observed according to age range and geographical scale.

CONCLUSION

There is no evidence supporting the effect of elite sport in increasing PA or sport participation in the general population. Decision makers and policymakers should be aware of this and invest in strategies such as those recommended by the World Health Organization.

An evidence-based assessment of the impact of the Olympic Games on population levels of physical activity

Pre-Olympic Games predictions commonly include an increase in population-based physical activity in the host city, as often stated in the bid, but the post-Olympic Games effects on physical activity have not been summarised. In this Series paper, we aim to do the following: examine mentions of a physical activity legacy in pre-Olympic bid documentation; analyse existing physical activity surveillance data collected before, during, and after the Olympic Games in hosting areas around the world; and evaluate Google Trends data surrounding the London 2012 Olympic Games as a case study of community interest in the topic of exercise during the time of the Olympic Games. Before 2007, little mention of physical activity was made in pre-Olympic Games documentation, but, after that, most documents had targets for population physical activity or sports participation. The synthesis of available surveillance data indicates that there was no change in the prevalence of physical activity or sports participation, except for the 2008 Summer Olympics in Beijing and the 1998 Winter Olympics in Nagano; although, the increase in participation in Nagano might not be attributable to the Olympic Games since there was no change in participation in winter sports. The Google Trends data showed an acute spike in searches with the term "Olympic" immediately associated with the London Olympic Games period and showed a sustained peri-Olympic increase in searches with the term "exercise". By themselves, the Olympic Games have not improved population-wide physical activity but might be an important missed public health opportunity. Such a legacy will require strategic planning and partnerships across the International Olympic Committee and the Olympic, sport, and public health agencies and a thorough evaluation framework implemented throughout the pre-Olympic Games and post-Olympic Games period in the host country.

The innovative role of Olympic sports and exercise in the promotion of health, gender equality and sustainability: past achievements and future challenges

Olympic sports represent, through their athletes, an iconic source of inspiration and ambition for everyone. During every Olympiad we are reminded of the astonishing achievements that can be reached through hard work and dedication. Nevertheless, these performances are very far from the reality of those being physically active to improve their health and fitness. The technological development that humanity has gone through in the last couple of centuries, has engineered physical activity out of our lives and dramatically altered our lifestyle, leading to the development of diseases that were not so prevalent. Exercise has become an integral part of our lives and it is now regarded as a medicine to prevent and counteract chronic conditions that are associated with a sedentary lifestyle. In this context Olympic sports can play a key role in attracting people to be physically active as well as leveraging on city governments to allow, not only sport participation, but a global active lifestyle. Therefore, International Sports Federations (ISF) have a central position in ensuring sports are in line with the changes occurring in society as well as fostering its natural evolution. Examples of this evolution are gender equality and sustainability, topics that finally are becoming central in ISFs as they have been in society for decades. Therefore, Olympic sports should acknowledge the prominent role they have in society and contribute to its further development by promoting socially relevant actions.

Innovation for Positive Sustainable Legacy From Mega Sports Events: Virtual Reality as a Tool for Social Inclusion Legacy for Paris 2024 Paralympic Games

There is significant interest in how sports events and their associated legacies could act as a platform to address global challenges and engender social change. The United Nations (UN) has acknowledged the important role that sport plays in supporting the UN 2030 Agenda for Sustainable Development and the Olympic movement could be argued as central to that objective. Yet critical questions and concerns have been raised about the growing expenditure, viability, long term legacy, and impacts of mega sports events such as the Olympic Games. While much evidence has focused on the challenges of creating legacy for Olympic Games, there is considerably less literature on understanding the Paralympic context. The purpose of this paper is to discuss the role of innovation in creating legacy from MSEs and propose a theoretical and methodological plan for such research. Innovation, a key driver in organizational performance, is suggested as essential to defining, planning for and measuring legacy. We specifically examine the potential of virtual reality (VR) as a technological innovation which can help create a social inclusion legacy in the context of Paris 2024 Olympic/Paralympic Games. A conceptual model is developed, which identifies legacy as a "wicked problem", and this paper discusses the importance of innovation with regards to legacy, by suggesting a new application for VR technology in the context of legacy related to social inclusion. Information technology is a valuable facilitator of social inclusion for individuals with a disability. We specifically examine the potential of VR as a technological innovation which can help create legacy through influencing unconscious biases (symbolic ableism) toward diversity such as disability, gender, and race.

Are young adults' discussions of public health nutrition policies associated with common food industry discourses? A qualitative pilot study

OBJECTIVE

Unhealthy diets are a key risk factor for chronic disease, with young adults (18-30 years old) in high-income countries like Australia and the UK particularly at risk. Improved public health nutrition policies can help address unhealthy diets in the population, but many of the more regulatory policies are opposed by food industry groups. This research explores how young adults in Australia and the UK discuss a range of topical public health nutrition policies and analyses whether and how their views may be associated with food industry discourses.

METHODS

Eight focus groups were held in Sydney, Australia, and Glasgow, UK, with a total of thirty young adults participating. A deliberative-style method was used in the focus groups to generate discussion about six public health nutrition policies, such as taxation of sugar-sweetened beverages and restrictions on advertising of less-healthy foods. Discourse analysis was used to examine participants' discussions.

RESULTS

Twenty discourse codes were developed iteratively from the focus group data. These were thematically linked with nine food industry discourses found in the peer-reviewed literature, including industry self-regulation, personal responsibility, corporate social responsibility and challenging nutrition science.

CONCLUSIONS

These results demonstrate there is an association between common food industry discourses and some young adults' views about public health nutrition policies. Implications for public health: Identifying, engaging with and responding to common industry discourses is a priority in order to build greater public support and acceptability of policies that will improve diet and prevent chronic disease.

Conditions under Which Trickle-Down Effects Occur: A Realist Synthesis Approach

Policy makers often legitimize bids for major sport events and public funding of elite sports by trickle-down effects, suggesting that hosting events, sporting success, and athlete role models inspire the population to participate themselves in sport and physical activity. According to previous review articles, empirical evidence of trickle-down effects are mixed, with several studies citing marginal or no effect. The purpose of this study is to apply a realist synthesis approach to evaluate under which conditions trickle-down effects occur (i.e., what works for whom under which circumstances?). Using rapid evidence assessment methodology, 58 empirical articles were identified in the search process and critically analyzed through the lens of realist synthesis evaluation. The analysis identified six conditions under which trickle-down effects have occurred: Event leveraging initiatives, capacity of community sport to cater for new participants, live spectating experiences, consumption possibilities on television or other media, and communities housing event venues. The findings have implications for the sustainability of sport policy decisions and public finance, as the likelihood of trickle-down effects increases with integrated planning and sustainable spending related to the above six conditions.

Physical Activity Among Urban-Living Middle-Aged and Older Japanese During the Build-Up to the Tokyo Olympic and Paralympic Games: A Population Study

This research examines physical activity (PA) parameters among urban-living middle-aged and older Japanese during the Tokyo Olympic build-up period. Population sampling was employed, and an online survey was administered with 4,000 adults across Japan's five largest cities. The International Physical Activity Questionnaire-Short Form constituted the main outcome variable, with auxiliary measures of Olympic interest and engagement, readiness for PA behavior change, perceived environmental barriers, and demographic information. Despite interest in the Olympics (>60% moderate-high interest), planned engagement with the event was low (>70% planned passive engagement). Higher levels of interest and planned engagement were both significantly correlated with greater self-reported PA participation (p < .001). Across the sample, the PA levels were in the low-moderate range (990 metabolic equivalent of task-min/week), with significant variations observed by the age-cohort and geographic area (p < .001). Age-cohort and geographic variations were also identified with regard to readiness for PA behavior change and perceived environmental barriers to activity (p < .001). Older age (65 years and above) and host city (Tokyo) residence emerged as correlates of higher levels of PA, greater readiness for behavior change, and fewer reported barriers to participation. These findings have implications for Olympic legacy management and successful transitions from middle age to later life in Japan.

Sport Promotion through Sport Mega-Events. An Analysis for Types of Olympic Sports in London 2012

A substantial amount of attention has been devoted towards the potential sport legacy of the Olympic Games. In spite of the increasing academic interest in this topic, there is a knowledge gap as far as sport legacy is concerned by types of different sports. The authors bridge this gap by analysing the evolution of 43 different Olympic/Paralympic sport modalities in the two-year period after the London 2012 Olympics. By using data from the Active People Survey with a sample of 165,000 people annually, and considering some demographic variables and the effect of the economic environment, the paper aims to test the existence of a sport legacy. We have applied time series analysis and ARIMA models for controlling for economic influence and seasonal adjustment and for making comparisons among participation rates. The results show, for the total of the sports analysed, that there were 336,000 individuals who increased their frequency of participation, while there was no significant increase in the number of new participants in these sports. When we develop the analysis for types of sports, London 2012 is positively associated not only with the frequency of participation in some types of sport but also with an increase in the number of new sport participants. Gender and age differences are also detected. The results show the differences of sport legacy by type of sports. Moreover, this research has elucidated an important unrecognised aspect of the effect of the Olympic Games and perhaps major events: that they can become a major policy tool for reversing sporting inequalities.

The sport participation legacy of major events in the UK

This paper examines the extent to which attending major sporting events leads to subsequent changes in the sport participation behaviour of spectators. The research covered seven single-sport events of World or European level held in the UK in 2014 and was concerned with spectators (aged 16 and over) who attended one of these events. Baseline data was gathered from a sample of spectators at each event using a face-to-face survey. Follow-up data was captured using an online survey at least nine months post-event. Our analysis is based on 258 people for whom both baseline and follow-up data were available (matched pairs). Using the Transtheoretical Model (TTM), the evidence from this research points to a small (net) positive staged change in sport participation among the sample overall. Variations in the nature and scale of changes associated with events featuring different sports were observed. Progression between the TTM stages was evident for individuals who were previously in the pre-preparation, preparation and action stages. The likelihood of progression appears to be strongest where prior contemplation for behaviour change was prevalent. Event attendance emerged as an important contributor for moving individuals along the TTM continuum, alongside a range of other factors. The demonstration or trickle-down effect was the primary mechanism by which any sport participation legacy supported by these events occurred. The practical applications of the research and the wider health benefits of leveraging event-induced sport participation increases are discussed.

Does the Olympic Agenda 2020 Have the Power to Create a New Olympic Heritage? An Analysis for the 2026 Winter Olympic Games Bid

The International Olympic Committee (IOC) lacks candidates willing to host the Olympic Games (OG) and has reacted to this situation by introducing the Olympic Agenda 2020 (OA)—a reform process making the OG more attractive for potential hosts. This study analyzes whether the OA plays a crucial role for the future of the OG. We, therefore, examined the official IOC documents and feasibility studies of the 2026 Winter Olympic Games (WOG) bidders and conducted qualitative interviews with experts in the field (n = 15). The results reveal that the 2026 WOG hosts plan to reduce the budgets for the organization and the infrastructure costs in the host regions. As a consequence, the number and nature of the sites and venues as well as the distances between them will increase. This means that the future Olympic heritage (OH) may lay less in iconic buildings but rather focus on the attempt to fulfil the city’s long-term strategies. Our analyses extend the literature by: (1) analysing the OA in view of future OG, (2) comparing experiences from past OG with those of current bidders, (3) integrating expert knowledge thanks to qualitative interviews and, finally, (4) considering new heritage concepts.

The effects of the London 2012 Olympics and related urban regeneration on physical and mental health: the ORiEL mixed-methods evaluation of a natural experiment

Background

There is limited evidence for public health policy-makers on the health impacts of urban regeneration programmes.

Objectives

To assess whether or not the London 2012 Olympic and Paralympic Games, and related urban regeneration, were associated with an increase in physical activity and mental health and well-being; to assess whether or not any benefits were sustained over time; and to capture the experiences of residents of the Olympic host boroughs.

Design

Quasi-experimental prospective cohort study of adolescents and their parents/carers, with a nested qualitative longitudinal study of families.

Setting

London boroughs of Newham, Barking and Dagenham, Tower Hamlets and Hackney.

Participants

A cohort of 2254 adolescents in 25 schools; a repeat cross-sectional study of parents/carers and a sample of 20 families for the qualitative study.

Intervention

The London 2012 Olympic and Paralympic Games, and urban regeneration primarily associated with the redevelopment of the Olympic Park for legacy use.

Primary outcome measures

Change in the proportion of respondents meeting physical activity recommendations (using self-reported physical activity); change in the proportion of respondents reporting depression and anxiety and change in well-being score.

Main results

At 6 months, adolescents who became inactive were less likely to come from the intervention borough (Newham) than from comparison boroughs [risk ratio (RR) = 0.69, 95% confidence interval (CI) 0.51 to 0.93]. At 18 months, there were no statistically significant differences between intervention and comparison boroughs for all adolescent physical activity and screen-time transitions. Those who visited the Olympic Park more than once a month were the least likely to remain inactive (RR 0.11, 95% CI 0.02 to 0.48) and the least likely to become inactive (RR 0.38, 95% CI 0.24 to 0.60) compared with those who were active at baseline and at the 18-month follow-up. No impacts on parental/carer physical activity were observed. Adolescents who were ‘no longer depressed’ (RR 1.53, 95% CI 1.07 to 2.20) or ‘remained depressed’ (RR 1.78, 95% CI 1.12 to 2.83) at 6 months were more likely to be from the intervention borough. For well-being, there was no association between boroughs and change in well-being between baseline and the 6-month follow-up. At 18 months’ follow-up, adolescents who ‘remained depressed’ (RR 1.93, 95% CI 1.01 to 3.70) were more likely to be from the intervention borough than from comparison boroughs. No associations were observed for well-being at 18 months. There was limited evidence of change for parental mental health and well-being. The qualitative study found that residents generally welcomed the unexpected chance to live in a cleaner, safer and more unified environment. The findings suggested that the Games temporarily alleviated certain stressors in the social and physical environment. Overall, the Games lessened participants’ sense of social exclusion and appeared to generate a sense of inclusion and respite, even if this was only temporary. Study limitations include the potential for adolescents to not be assigned the correct level of exposure to urban regeneration and the effect of reductions in central and local public budgets owing to the UK Government’s deficit reduction programme.

Conclusions

This study provided the highest quality data to date on the short- and medium-term social and health impacts of sporting mega-events. We found limited evidence that the London 2012 Olympic and Paralympic Games had a positive effect on adolescent or parental physical activity, mental health or well-being.

Automobile, construction and entertainment business sector influences on sedentary lifestyles

Sedentary lifestyles contribute to premature death and health inequalities. Researchers have studied personal and community-level determinants of inactivity but few have analyzed corporate influences. To reframe the public health debate on inactivity and open new doors for public sector intervention, we conducted a scoping review of evidence from several disciplines to describe how the business and political practices of the automobile, construction, and entertainment sectors have encouraged sedentary lifestyles. In the last 50 years, these industries have found it profitable to produce motor vehicles, housing, and entertainment, which intentionally or unintentionally discourage physical activity. Ceding primary authority for policy decisions in these sectors to the market-based economy has enabled the growth of powerful lobbies that encourage and maintain sedentary lifestyles. To counteract these influences, public health and civil society need to confront more upstream economic and social determinants of sedentary lifestyles. Building on evidence from efforts to change harmful tobacco, alcohol and food industry practices, we propose the creation of research and policy agendas that contribute to public health practice that can modify corporate practices that contribute to physical, social and political environments that discourage physical activity.

Analysis of the Coverage of Paratriathlon and Paratriathletes in Canadian Newspapers

From recreational to elite levels, sport has many benefits for disabled people. At the same time, it is acknowledged that there is a trickle-down problem from para-elite sport to sport participation of disabled people, in general. Newspapers are one form of media that sets agendas and influences public opinion. Many studies have highlighted problematic aspects of parasport and para-athlete coverage in newspapers. Paratriathlon was one of two new events added to the Paralympics in Rio 2016, which increased its visibility in the public domain. We investigated the coverage of paratriathlon and paratriathletes in 300 Canadian newspapers using the ProQuest database Canadian Newsstream as a source, and utilizing a descriptive quantitative and a qualitative thematic content analysis. The main themes evident in the reporting on paratriathlon and paratriathletes, in the three hundred Canadian newspapers we covered, were the supercrip imagery of the para-athlete, personal stories mostly linked to the supercrip imagery, and the theme of able-bodied athletes in juxtaposition to the para-athletes. Using the lens of the four legacy goals of the International Paralympic Committee, we conclude that our findings are detrimental to the fulfillment of the four legacy goals.

Inaugural HealthAccord Conference (SportAccord Convention, Bangkok, Thailand): The Power of Sport - The Power to Change

SportAccord organized the inaugural HealthAccord conference on April 19, 2018, in Bangkok, Thailand. The goal of HealthAccord is for the International Sport Federations (IF) and sport industry leaders to address high-priority issues facing sport through a serious commitment to innovation to protect athlete health, to enhance athlete performance, and to stimulate action to improve global health through the promotion of physical activity. The first HeathAccord conference was organized by drawing on the knowledge and experience of experts from global health programs focused on athletes and global citizens, respectively. The first session, "The Power of Sport," addressed the application of "state of the art" sport science and sport medicine for the protection of athlete health and to enhance sport performance. "The Power of Sport" session concentrated on enabling athletes to perform spectacular feats that are "higher, stronger, faster" intended to engage and thrill global audiences without resorting to prohibited substances and methods, to enable athletes to remain active in sport for a longer career, and to increase the attraction of sport for sponsors. In the second session, "The Power to Change," sport was viewed as having an important role in promoting physical activity within their respective federations, community, and internationally. The Olympic movement, IF, and other sport stakeholders are urgently needed to become the social drivers to correct the mismatch between physical activity for health development and draw toward sedentary lifestyles of the modern world. Key outcomes of this first HealthAccord conference were the agreement among participants to develop an innovative and high-impact collaboration between IF and related stakeholders; to use sport as a social movement platform to measurably improve health, both for athletes and for global citizens.

Can international elite sport success trickle down to mass sport participation? Evidence from Danish team handball

Many scholars do not find evidence of a trickle-down effect from elite sport success to mass sport participation. Contrary to what is assumed by the trickle-down effect "theorem", successful elite sportspeople do not seem to inspire amateurs to take up sport themselves. However, recent studies present evidence that elite sport can have an influence. In this article, we apply regression models on time series data from one of the most successful Danish sports, team handball. Our findings are mixed, but lean towards supporting scholars who argue that trickle-down effects are not necessarily an inherent part of international sporting success. Further studies should examine more sports to identify where trickle-down effects occur and why.

From Delivery to Adoption of Physical Activity Guidelines: Realist Synthesis

BACKGROUND

Evidence-based guidelines published by health authorities for the promotion of health-enhancing physical activity (PA), continue to be implemented unsuccessfully and demonstrate a gap between evidence and policies. This review synthesizes evidence on factors influencing delivery, adoption and implementation of PA promotion guidelines within different policy sectors (e.g., health, transport, urban planning, sport, education).

METHODS

Published literature was initially searched using PubMed, EBSCO, Google Scholar and continued through an iterative snowball technique. The literature review spanned the period 2002-2017. The realist synthesis approach was adopted to review the content of 39 included studies. An initial programme theory with a four-step chain from evidence emersion to implementation of guidelines was tested.

RESULTS

The synthesis furthers our understanding of the link between PA guidelines delivery and the actions of professionals responsible for implementation within health services, school departments and municipalities. The main mechanisms identified for guidance implementation were scientific legitimation, enforcement, feasibility, familiarity with concepts and PA habits. Threats emerged to the successful implementation of PA guidelines at national/local jurisdictional levels.

CONCLUSIONS

The way PA guidelines are developed may influence their adoption by policy-makers and professionals. Useful lessons emerged that may inform synergies between policymaking and professional practices, promoting win-win multisectoral strategies.

Determinants of evidence use in public health policy making: Results from a study across six EU countries

The knowledge-practice gap in public health is widely known. The importance of using different types of evidence for the development of effective health promotion has also been emphasized. Nevertheless, in practice, intervention decisions are often based on perceived short-term opportunities, lacking the most effective approaches, thus limiting the impact of health promotion strategies. This article focuses on facilitators and barriers in the use of evidence in developing health enhancing physical activity policies. Data was collected in 2012 by interviewing 86 key stakeholders from six EU countries (FI, DK, UK, NL, IT, RO) using a common topic guide. Content analysis and concept mapping was used to construct a map of facilitators and barriers. Barriers and facilitators experienced by most stakeholders and policy context in each country are analysed. A lack of locally useful and concrete evidence, evidence on costs, and a lack of joint understanding were specific hindrances. Also users' characteristics and the role media play were identified as factors of influence. Attention for individual and social factors within the policy context might provide the key to enhance more sustainable evidence use. Developing and evaluating tailored approaches impacting on networking, personal relationships, collaboration and evidence coproduction is recommended.

Is Olympic inspiration associated with fitness and physical activity in English schoolchildren? A repeated cross-sectional comparison before and 18 months after London 2012

OBJECTIVES

To compare cardiovascular fitness and physical activity of schoolchildren 18 months after London 2012 according to Olympic 'inspiration'.

DESIGN

A cross-sectional comparison between groups of schoolchildren categorised according to self-reported Olympic inspiration and a repeated cross-sectional comparison using data collected pre-2012.

SETTING

Schools within a 50 km radius of the Olympic Park, Stratford, London.

PARTICIPANTS

931 students (10.0-15.9-year-olds) attending 6 schools assessed in 2013 and 2014 (18 (range: 14-20) months after London 2012) and 733 students from the same schools assessed in 2008-2009 (42 (range: 38-46) months before London 2012).

PRIMARY OUTCOME MEASURES

Self-reported Olympic inspiration; cardiorespiratory fitness ([Formula: see text] mL/kg/min) assessed using the 20 m shuttle-run and self-reported physical activity.

SECONDARY OUTCOMES MEASURES

Differences in [Formula: see text] before and after London 2012.

RESULTS

53% of children reported being inspired to try new sports or activities. Compared with those not inspired by the Games, [Formula: see text] was higher in boys (d=0.43) and girls (d=0.27), who continued to participate in activities at 18(14-20) months. This 45% of sample was also more physically active (boys, d=0.23; girls, d=0.38) than those not or only briefly inspired to participate in activities (boys, d=0.24; girls, d=0.21). Compared with pre-2012 values, [Formula: see text] was lower post-2012 in boys (d=0.37) and in girls (d=0.38).

CONCLUSIONS

High levels of inspiration to participate in new activities reported following London 2012 and positive associations with fitness are encouraging. We cannot discount the possibility that inspired participants may have already been fitter and more active pre-2012. These associations must be interpreted in the context of the significant declines in fitness shown by our repeated cross-sectional comparison. Olympic host countries should employ longitudinal monitoring using objectively measured fitness and physical activity to provide evidence of health-related legacy.

Quality of life of residents living in a city hosting mega-sport events: a longitudinal study

BACKGROUND

It remains unknown whether and when the hosting of mega-sport events increases quality of life of host city residents. The aim of this study is to assess the changes in quality of life of host city residents over the course of hosting a mega-sport event until three months after the event, depending on residents' perception of the atmosphere during the event.

METHODS

The study was conducted in Rio de Janeiro, one of the host cities of the 2014 FIFA World Cup in soccer. Participants were recruited from a Brazilian market research agency's panel and surveyed online. The WHOQOL-BREF was used to measure quality of life of residents of Rio de Janeiro (n = 281) in three waves in the context of the 2014 FIFA World Cup. Perceived atmosphere at the event was measured via an established scale. Piecewise latent growth models were used to analyze individual changes in the four domains of quality of life per se and depending on perceived atmosphere.

RESULTS

There was no change in quality of life with respect to physical, social, psychological, and environmental health for all participants during the course of the event. However, residents who perceived a positive atmosphere rated the social and environmental domains of quality of life more positively right after the end (vs. at the beginning) of the World Cup. This increase sustained until three months after the event. Physical health (particularly at high levels of perceived atmosphere) and psychological health decreased from right after the event until three months after.

CONCLUSIONS

There was no positive effect of the hosting of the mega-sport event on the four quality of life domains of the panel members (who were residents of a city hosting a mega-sport event) per se. The individual changes in quality of life vary by perception of atmosphere and by domain of quality of life.

Does being an Olympic city help improve recreational resources? Examining the quality of physical activity resources in a low-income neighborhood of Rio de Janeiro

OBJECTIVES

To assess the quality of public physical activity resources (PARs) in a low socio-economic community in the Olympic city of Rio de Janeiro.

METHODS

The Physical Activity Resource Assessment (PARA) instrument was used to assess all 29 public PARs located in this community. A quality indicator (QI) was developed based on PARA results.

RESULTS

The average QI of the areas assessed was 1.3 ± 6.40 and the median 1 point, a considerably low score if compared to scores of public PARs across the city (13.6 ± 4.91 and 13 points).

CONCLUSIONS

The urban regeneration necessary for hosting mega-sport events is frequently promoted as an opportunity to enhance PARs and therefore to improve health through physical activity (PA) participation. Findings indicate that the high number of elements that can discourage the use of these spaces may help explain the low level of PA during leisure time that has been previously reported of residents of the same neighborhood. Whether using the Olympic Games as catalyst or not, policies designed to encourage PA should focus also on the built environment.

Smoke Rings: Towards a Comprehensive Tobacco Free Policy for the Olympic Games

BACKGROUND

The tobacco industry has long sought affiliation with major sporting events, including the Olympic Games, for marketing, advertising and promotion purposes. Since 1988, each Olympic Games has adopted a tobacco-free policy. Limited study of the effectiveness of the smoke-free policy has been undertaken to date, with none examining the tobacco industry's involvement with the Olympics or use of the Olympic brand.

METHODS AND FINDINGS

A comparison of the contents of Olympic tobacco-free policies from 1988 to 2014 was carried out by searching the websites of the IOC and host NOCs. The specific tobacco control measures adopted for each Games were compiled and compared with measures recommended by the WHO Tobacco Free Sports Initiative and Article 13 of the Framework Convention on Tobacco Control (FCTC). This was supported by semi-structured interviews of key informants involved with the adoption of tobacco-free policies for selected games. To understand the industry's interests in the Olympics, the Legacy Tobacco Documents Library (http://legacy.library.ucsf.edu) was systematically searched between June 2013 and August 2014. Company websites, secondary sources and media reports were also searched to triangulate the above data sources. This paper finds that, while most direct associations between tobacco and the Olympics have been prohibited since 1988, a variety of indirect associations undermine the Olympic tobacco-free policy. This is due to variation in the scope of tobacco-free policies, limited jurisdiction and continued efforts by the industry to be associated with Olympic ideals.

CONCLUSIONS

The paper concludes that, compatible with the IOC's commitment to promoting healthy lifestyles, a comprehensive tobacco-free policy with standardized and binding measures should be adopted by the International Olympic Committee and all national Olympic committees.

Public health policy and walking in England-analysis of the 2008 'policy window'

BACKGROUND

Although the government in England has a long-standing interest in walking promotion, this has not been accompanied by a coherent strategic plan or investment to support physical activity behaviour change. However, in 2008 the government announced its intention to invest £7 million into walking promotion. This article utilises Kingdon's Multiple Streams framework as an organising principle through which to interrogate the reasons behind the increased emphasis on walking promotion as part of the public health policy agenda in England.

METHODS

The research adopted a case study design. Data were obtained through document analysis of relevant policies and semi-structured interviews with experts in the walking sector, including both government and non-government representatives.

RESULTS

Kingdon's Multiple Streams theory proposes that at certain points in time, 'policy windows' are created through the convergence of a problem, an appropriate solution, and a receptive political environment, and this policy window presents an opportunity for major policy change. The findings of this research suggest that the success of London in securing the 2012 Olympic and Paralympic Games was the primary trigger in the creation of a policy window for walking promotion in recent years.

CONCLUSIONS

Despite previous interest in walking promotion from the health and transport sectors, it was the recent alignment with the sports agenda that led to increased political commitment. This raises concerns that the research evidence on the health benefits of physical activity and rising levels of inactivity in England, are insufficient to secure government support and investment, and that multi-sector lobbying and joined-up political action may be critical in advancing this agenda.

Secular Trends in Overweight and Obesity among Urban Children in Guangzhou China, 2007-2011

BACKGROUND

No studies have been reported on children obesity prevalence of Guangzhou, one of the most urbanized areas in China. This study tracks the secular trends of obesity prevalence of children.

METHODS

The data were derived from the surveys on students' constitution and health carried out by government. Randomly, 3832 students in 2007, 13141 in 2008, 14052 in 2009, 13750 in 2010, and 15225 in 2011, aged 7-12 years, from urban primary school were examined. Anthropometric parameters were measured in all students.

RESULTS

The mean of body mass index increased significantly from 16.6 in 2008 to 16.8 in 2011 in the total group of children, and the total prevalence of overweight and obesity increased from 9.4 and 6.2 to 10.5 and 7.5 from 2007 to 2011, respectively. The minimum value of the mean body mass index and the overweight and obesity prevalence in the total age group all appeared in 2008. The prevalence of overweight and obesity in males was significantly higher than that in females in each year among the 5 years.

CONCLUSION

Although the prevalence of children obesity in Guangzhou in 2011 is still lower than the average values of Chinese large coastal cities, a significant increase was found in their prevalence from 2007 to 2011 and the total obesity prevalence of children is even higher than that of adolescent. Furthermore, we found that the minimum value of overweight and obesity prevalence of the total group and almost all gender-specific age groups appeared in 2008.

The impact of the Vancouver Winter Olympics on population level physical activity and sport participation among Canadian children and adolescents: population based study

Background

There has been much debate about the potential impact of the Olympics. The purpose of this study was to determine if hosting the 2010 Vancouver Olympic Games (OG) encouraged Canadian children to be physically active.

Methods

Children 5–19 years (n = 19862) were assessed as part of the representative Canadian Physical Activity Levels Among Youth surveillance study between August 2007 and July 2011. Parents were asked if the child participated in organized physical activity or sport. In addition, children wore pedometers for 7 days to objectively provide an estimate of overall physical activity. Mean steps/day and percent participating in organized physical activity or sport were calculated by time period within year for Canada and British Columbia. The odds of participation by time period were estimated by logistic regression, controlling for age and sex.

Results

Mean steps were lower during the Olympic period compared with Pre- (607 fewer steps/day 95% CI 263–950 steps/day) and Post-Olympic (1246 fewer steps 95% CI 858–1634 steps) periods for Canada. There was no difference by time period in British Columbia. A similar pattern in mean steps by time period was observed across years, but there were no significant differences in activity within each of these periods between years. The likelihood of participating in organized physical activity or sport by time period within or across years did not differ from baseline (August-November 2007).

Conclusion

The 2010 Olympic Games had no measurable impact on objectively measured physical activity or the prevalence of overall sports participation among Canadian children. Much greater cross-Government and long-term efforts are needed to create the conditions for an Olympic legacy effect on physical activity.

No lasting legacy: no change in reporting of women's sports in the British print media with the London 2012 Olympics and Paralympics

BACKGROUND

The proportion of media sports coverage devoted to women is reported at between 1 and 6%. Our survey examines and compares reporting patterns before and after the 2012 Olympics and Paralympics.

METHODS

We collected data on sports coverage in six national newspapers on 3 weekend days in February and March 2012, and in February 2013; ∼5 months before the opening of the 2012 Olympic Games and 5 months after the closing of the Paralympic Games.

RESULTS

In 2012, 39 of 876 articles in national newspapers (4.5%) related to women's sports, compared with 22 of 755 (2.9%) in 2013; a non-significant reduction in coverage [difference 1.54%, 95% confidence interval (CI) -0.28 to 3.36). In 2012, 24 of 647 pictures (3.7%) related to women's activities, compared with 10 of 738 (1.4%) in 2013; a significant reduction in coverage (difference 2.35%; 95% CI 0.68-4.03). The median area per article was significantly greater for men in both years.

CONCLUSIONS

We found a continuing bias towards men's sport in the media analysed and no evidence of improvement either before or after the 2012 Olympics and Paralympics. Increased support of women's sport in the print media could benefit individuals and influence the health of the population.

Watching sport on television, physical activity, and risk of obesity in older adults

Background

Television (TV) viewing has been associated with obesity although the effects of specific TV content on health and other behaviours remains unknown. We examined the association between watching sport on TV, physical activity levels, and risk of obesity.

Methods

We studied 6,733 (aged 64.9 ± 9.2 yrs) men and women from the English Longitudinal Study of Ageing, a prospective study of community dwelling older adults. Data were collected on self reported TV time and content, and physical activity. Nurses measured height and weight for the calculation of body mass index.

Results

On average, participants reported viewing TV for 5.3 ± 4.1 hours per day and 30.3% of the sample watched sport on TV at least twice a week. There was no association between watching sport and physical activity levels. Participants that watched sports every day were at higher risk of obesity [odds ratio = 1.39, 95% CI, 1.15, 1.68) after adjustment for age, sex, smoking, alcohol, physical activity, total TV time, disability, and self-rated health.

Conclusions

Watching elite athletes may have no role in the promotion of physical activity in older adults, which has implications for staging large sporting events with physical activity legacy promises.

Physical activity for the prevention and treatment of major chronic disease: an overview of systematic reviews

BACKGROUND

The evidence that higher levels of physical activity and/or lower levels of physical inactivity are associated with beneficial health-related outcomes stems mainly from observational studies. Findings from these studies often differ from randomised controlled trials and systematic reviews currently demonstrate mixed results, due partly to heterogeneity in physical activity interventions, methodologies used and populations studied. As a result, translation into clinical practice has been difficult. It is therefore essential that an overview is carried out to compare and contrast systematic reviews, and to identify those physical activity interventions that are the most effective in preventing and/or treating major chronic disease. This protocol has been registered on PROSPERO 2013: CRD42013003523.

METHODS

We will carry out an overview of Cochrane systematic reviews. We will search the Cochrane Database of Systematic Reviews for systematic reviews of randomised controlled trials that have a primary focus on disease-related outcomes. We will restrict reviews to those in selected major chronic diseases. Two authors will independently screen search outputs, select studies, extract data and assess the quality of included reviews using the assessment of multiple systematic reviews tool; all discrepancies will be resolved by discussing and reaching a consensus, or by arbitration with a third author. The data extraction form will summarise key information from each review, including details of the population(s) (for example, disease condition), the context (for example, prevention, treatment or management), the participants, the intervention(s), the comparison(s) and the outcomes. The primary outcomes of interest are the prevention of chronic disease and/or improved outcomes, in the treatment or management of chronic disease. These outcomes will be summarised and presented for individual chronic diseases (for example, any change in blood pressure in hypertension or glucose control in diabetes). Secondary outcomes of interest are to describe the structure and delivery of physical activity interventions across chronic disease conditions and adverse events associated with physical activity.

DISCUSSION

We anticipate that our results could inform researchers, guideline groups and policymakers of the most efficacious physical activity interventions in preventing and/or managing major chronic disease.
