Abstract
We aimed to identify, describe and analyse school environment assessment (SEA) tools that address behavioural risk factors (unhealthy diet, physical inactivity, tobacco and alcohol consumption) for non-communicable diseases (NCD). We searched in MEDLINE and Web of Science, hand-searched reference lists and contacted experts. Basic characteristics, measures assessed and measurement properties (validity, reliability, usability) of identified tools were extracted. We narratively synthesized the data and used content analysis to develop a list of measures used in the SEA tools.
Twenty-four SEA tools were identified, mostly from developed countries. Out of these, 15 were questionnaire based, 8 were checklists or observation based tools and one tool used a combined checklist/observation based and telephonic questionnaire approach. Only 1 SEA tool had components related to all the four NCD risk factors, 2 SEA tools has assessed three NCD risk factors (diet/nutrition, physical activity, tobacco), 10 SEA tools has assessed two NCD risk factors (diet/nutrition and physical activity) and 11 SEA tools has assessed only one of the NCD risk factor. Several measures were used in the tools to assess the four NCD risk factors, but tobacco and alcohol was sparingly included. Measurement properties were reported for 14 tools.
The review provides a comprehensive list of measures used in SEA tools which could be a valuable resource to guide future development of such tools. A valid and reliable SEA tool which could simultaneously evaluate all NCD risk factors, that has been tested in different settings with varying resource availability is needed.

Physical activity and food environments: solutions to the obesity epidemic.
James Sallis, Karen Glanz (2009)
Environmental, policy, and societal changes are important contributors to the rapid rise in obesity over the past few decades, and there has been substantial progress toward identifying environmental and policy factors related to eating and physical activity that can point toward solutions. This article is a status report on research on physical activity and food environments, and it suggests how these findings can be used to improve diet and physical activity and to control or reduce obesity. This article summarizes and synthesizes recent reviews and provides examples of representative studies. It also describes ongoing innovative interventions and policy change efforts that were identified through conference presentations, media coverage, and websites. Numerous cross-sectional studies have consistently demonstrated that some attributes of built and food environments are associated with physical activity, healthful eating, and obesity. Residents of walkable neighborhoods who have good access to recreation facilities are more likely to be physically active and less likely to be overweight or obese. Residents of communities with ready access to healthy foods also tend to have more healthful diets. Disparities in environments and policies that disadvantage low-income communities and racial minorities have been documented as well. Evidence from multilevel studies, prospective research, and quasi-experimental evaluations of environmental changes are just beginning to emerge. Environment, policy, and multilevel strategies for improving diet, physical activity, and obesity control are recommended based on a rapidly growing body of research and the collective wisdom of leading expert organizations. A public health imperative to identify and implement solutions to the obesity epidemic warrants the use of the most promising strategies while continuing to build the evidence base.

Diet and Physical Activity for the Prevention of Noncommunicable Diseases in Low- and Middle-Income Countries: A Systematic Policy Review
Carl Lachat, Stephen Otchere, Dominique Roberfroid … (2013)
Introduction Noncommunicable diseases (NCDs) are the leading cause of death globally. Of the 57 million global deaths in 2008, 36 million (63%) were due to NCDs, principally cardiovascular diseases, diabetes, cancers, and chronic respiratory diseases [1]. Mortality and morbidity data reveal the growing and disproportional impact of the epidemic in low- and middle-income countries (LMICs). Nearly 80% of the yearly NCD deaths—equivalent to 29 million people—are estimated to occur in LMICs. Without effective prevention and control, an estimated 41 million people in LMICs will die from NCDs by 2015 [2]. NCDs will evolve into a staggering economic burden over the next two decades [3]. Poor dietary quality (in particular, high salt intake, high saturated and trans-fatty acid intake, and low fruit and vegetable consumption) and insufficient physical activity are key risk factors for NCD development [4] and mortality worldwide [5], and are considered priority areas for international action [6]. The mean salt intake in most LMICs exceeds the recommended maximum intake [7]. Reducing salt intake to about 6 g/d could prevent annually about 2.5 million deaths globally [8]–[11], and a 15% reduction of salt intake over a decade in LMICs could forestall 3.1 million deaths [11],[12]. Fruit and vegetable intake is inadequate [13], and this situation contributes to 2.7 million NCD-related deaths per year. Despite evidence indicating that proper levels of physical activity are associated with a 30% reduction in the risk of ischemic heart disease, a 27% reduction in the risk of diabetes, and a 21%–25% reduction in the risk of breast and colon cancer [14],[15], approximately 3.2 million deaths each year are attributable to insufficient physical activity [6]. Physical inactivity is increasingly becoming prevalent in LMICs and already constitutes one of the leading causes of mortality [16]. There is also concern about excess intake of saturated and transfatty acids in LMICs, although large regional differences are observed [17],[18]. Preventing NCDs is not impossible [19]. Cecchini and colleagues analyzed population-based strategies to prevent NCDs in a number of LMICs with a high burden of NCDs [4]. Health information and communication strategies, fiscal measures, and regulatory measures for marketing or provision of nutrition information to children that promotes healthy eating and physical activity were found to yield substantial and cost-effective health gains, in particular in LMICs [4]. In addition, these interventions were found to be particularly effective when delivered as a multi-intervention package. Hence, it is crucial to translate the available evidence into sustainable policies in LMICs [6]. In May 2004, all WHO member states endorsed the Global Strategy on Diet, Physical Activity and Health, aiming to address NCDs through diet and physical activity [20]. Recently, a United Nations high-level meeting convened to discuss measures to prevent and control the global NCD epidemic and stressed the need to accelerate the policy response to it [21]. Monitoring this international commitment is important and can be achieved by systematic policy reviews. Previous policy reviews [22],[23], however, provided only a partial view of efforts undertaken to address NCDs, as they relied on survey data and did not consider the actual content of the policies. As policy documents are the culmination of existing social processes, they reflect the views of various stakeholders and are considered to be a reliable account of prevailing policy paradigms in a country [24]. We carried out a stocktaking exercise on national policy actions for NCD prevention in LMICs, and assessed the extent to which these address critical risk factors for NCDs, i.e., salt, fat, and fruit and vegetable intake, and physical inactivity. We focused on the existence and content of policies for the prevention of NCDs, not on their actual implementation. Methods Collection of Policy Documents We searched the Internet (key words [“Nutrition” OR “NCD”] AND [“Policy” OR “Strategies” OR “Actions”]) for all publicly available national policies related to diet, nutrition, NCDs, and health in the countries classified as LMICs by the World Bank in 2011 [25]. We also searched the websites of the national ministries involved in nutrition or NCD prevention (i.e., ministries of health, sports, welfare, social affairs, or agriculture) and government portals as well as national nutrition societies. For those countries for which no policy was retrieved through the web search, an e-mail request stating the purpose of the study was sent to the respective bodies. A similar e-mail request was also sent to the WHO Regional Offices and to personal contacts of the research team. When no reply was obtained after repeated contact attempts and no reference to the existence of relevant policy documents was found during our Internet search, we classified the country as one for which we were unable to assess availability of policies. In addition to our search, we used the policy database of the WHO Regional Office for Europe [26] to assess policy availability. Screening and Selection of Documents The following inclusion criteria were used to include the policies in the analysis: (i) the policy is from a country classified as LMIC according to 2011 World Bank classification [25], (ii) the policy is officially approved by the national government, (iii) the policy is a publicly available document, published between 1 January 2004 and 1 January 2013, and (iv) the policy relates directly or indirectly to prevention of NCDs (Text S1). We report our findings as a systematic policy review (Text S2). Because we present our results by WHO region, we also excluded countries that were not official member states of WHO in 2011. There was no language restriction. The definitions of “policy,” “action plan,” and “program” vary broadly among the national documents. For the purpose of the present review, a broad definition of policy was used, and all national documents that included the national objectives and guidelines for action in the domain of diet and/or physical activity and/or prevention of NCDs were included. No document was excluded based on its title (e.g., “plan” versus “policy” versus “strategy”). Data Analysis Structured content analysis was conducted by coding the documents in NVivo 8 (QSR International). The documents were coded independently by two researchers to minimize bias induced by subjective coding. The coded documents were compared, and if coding agreement was 30% of total calories, compared to the First Malaysian Food Consumption Survey; Viet Nam: Proportion of households with a diet with 14% of protein, 16% of lipids and 5–68% of carbohydrates is 50% by 2015 and 75% by 2020 WHO classification of regions and countries was followed. Four of the countries (Mayotte, West Bank and Gaza, the Republic of Kosovo, and American Samoa) classified as LMICs by the World Bank in 2011 [25] were not WHO member states in 2011. a The policy document of FYRM reports that goals are in line with those of WHO [106]. The stated goal of 400 g/d Cuba: Increase the proportion of the population consuming at least 200 g of FV by 40% and consuming at least three portions of vegetables per day or 300 g by 50%; Jamaica: A 20% increase in consumption of FV by December 2008; Brazil: Increase FV consumption Indonesia: Increase consumption of FV daily; Bangladesh: Increase production of noncereal crops (FV, oilseeds, pulses) Fiji: Increase intake of FV and promote healthy and safe diets to reduce NCDs; Malaysia: Diversify diets to increase the consumption of micronutrient-rich foods including FV; increase proportion of people consuming FV; Mongolia and Samoa: Increase the consumption of FV by households; Philippines: Increase per capita total vegetable consumption from 111 g/d to 133 g/d WHO classification of regions and countries was followed. Four of the countries (Mayotte, West Bank and Gaza, the Republic of Kosovo, and American Samoa) classified as LMICs by the World Bank in 2011 [25] were not WHO member states in 2011. FV, fruits and vegetables; FYRM, the former Yugoslav Republic of Macedonia; NR, not reported. Policy Actions to Increase Physical Activity and Address Sedentary Lifestyle Public education and sensitization were the main strategies to promote physical activity in the policies (Table 4). Whereas countries such as Morocco [59], Mongolia [69], and Mauritius [63] targeted educational institutions, others, such as Bhutan [66], Guyana [79], and Malaysia [76], focused on workplaces. Samoa [80], the Niger [61], Indonesia [81], India [82], and Cambodia [71] targeted the community at large. Nine countries (Kenya [60], Morocco [59], Cuba [83], Uruguay [58], Jamaica [65], Brazil [75], Malaysia [76], the Philippines [73], and China [84]) proposed national policy targets for physical activity (Table 4). 10.1371/journal.pmed.1001465.t004 Table 4 National policy actions and targets to promote physical activity by WHO region and target group.

FYRM, the former Yugoslav Republic of Macedonia; NGO, nongovernmental organization; NR, not reported; PA, physical activity. Four countries' policy documents (Georgia [57], Mongolia [69], Mauritius [63], and Chile [85]) contained detailed actions and elaborated an implementation plan for stakeholders. The need to develop sports infrastructure and urban planning (e.g., bicycle lanes and recreational centers) featured in the policy documents of Georgia [57], the Republic of Moldova [86], Turkey [62], and Mongolia [69], for instance. Five countries (Mauritius [63], Brazil [75], Samoa [80], the Republic of Moldova [86], and Serbia [87]) mentioned the need to promote physical activity among the elderly. Only four countries (Bhutan [66], the Philippines [73], Cuba [83], and the Republic of Moldova [86]) outlined specific strategies to address sedentary lifestyles, and five (Turkey [62], Cambodia [71], Jamaica [65], Serbia [87], and India [82]) documented explicit actions to involve the private sector in the promotion of physical activity. Discussion Despite the global disease burden of NCDs in LMICs, policies that address at least one risk factor for NCDs were found in a minority of the LMICs reviewed, and only a handful of them comprehensively tackled NCDs through integrated action on various risk factors. Even if the 24 countries with unknown existence of a NCD prevention policy actually have such a policy, the proportion with countries tackling a risk factor would amount to 56% (78/140). This finding is discouraging, because in 2004, all countries expressed a strong commitment to action to address lifestyle, diet, and physical activity [20]. Our results show that, in spite of that official commitment, most LMICs are poorly prepared to tackle the NCD increase and that little progress has been made in recent years. This finding is consistent with the results of Alwan et al. [23], who reported the results of a survey in 2010 that was limited to countries with high NCD-related mortality. Most of the policies in our review were poorly accessible and were only obtained after an extensive search or through personal contacts. Such a situation is certainly not favorable for benchmarking and communication of policies. In agreement with Sridhar et al. [88], we argue how better sharing of best practices and lessons learned with regard to policy development is needed to address the current NCD pandemic. Additional instruments and platforms to share lessons learned in policy development and implementation are needed. Policy databases with links to documents were created previously, but are restricted to nutrition action [89] or the European region [26]. An open-access, full-text global repository of initiatives and policies to address NCDs would be a great step forward. It could also contribute to global leadership and shared accountability in the global fight against NCDs, an issue that is long overdue [90]. Ideally, such a policy database would be connected to surveillance data on the main NCD risk factors, as suggested previously [23], and would facilitate tracking progress in the coming years. We are ready to organize such an open-access repository and invite interested policy makers to contact us for an update of the current database. Priority setting and clear articulation of what needs to be done by stakeholders is a second key issue that emerged in this analysis. Countries seasoned in the fight against NCDs develop comprehensive strategies that focus on critical risk factors and what is expected of stakeholders [91]. In the present analysis, the level of detail and outlining of the organization of policy actions to undertake was generally discouraging. Only a minority of the policies reviewed surpassed description of policy actions and included a budget, implementation plan, time frame, and devolvement of responsibility for strategies to combat specific risk factors. Various policies describe strategies and actions for NCD prevention as “the need to develop and review dietary guidelines and recommendations for people suffering from nutrition-related NCDs” or use generic statements such as “create awareness of healthy eating lifestyle to control NCDs.” Such general statements are not informative, and clear actions need to be outlined in the policies to mobilize stakeholders for effective action [92]. Since its inception during the 1992 International Conference on Nutrition [93], the approach to streamline nutrition action in national policies has had limited success, partly because of the lack of strong leadership and commitment to lead concerted action involving various stakeholders [94]. The current scientific evidence and international experience in the fight against NCDs consistently indicates the need for comprehensive and integrated action on various risk factors [95]. Mobilization of the main actors—in particular, governments, international agencies, the private sector, civil society, health professionals, and individuals—is imperative [96]. An important limitation of most policies included in the analysis is the absence of plans, mechanisms, and incentives to foster multi-stakeholder and cross-sector collaboration. The food and nonalcoholic beverage industry, for instance, can play a role in the promotion of healthier lifestyles. However, before engaging with the private sector, government agencies should be aware of the need to manage potential conflicts of interest between the government and the private sector and should try to address these by defining clear roles, responsibilities, and targets to be achieved as a result of their collaboration [97]. Most strategies encountered in the policies were directed towards government agencies and consumers, and few were targeted at the business community, international agencies, or civil society. The United Nations Political Declaration on NCDs makes a strong call for multi-stakeholder partnerships to be leveraged for effective prevention of NCDs. Policy makers in LMICs may need additional support for the development of multi-stakeholder collaborations to address the burden imposed by NCDs as well as their root causes. In our review of governmental policies relating to NCD prevention in LMICs, strategies to increase fruit and vegetable intake were the most frequent dietary action for NCD prevention. This is hardly surprising, as fruit and vegetable interventions were taken up early on in LMICs, primarily to address prevailing micronutrient deficiencies such as vitamin A deficiency [98]. Many of these experiences, however, are restricted to the development of food-based dietary guidelines or incentives targeted towards the agricultural sector. Policy measures to achieve better diet will require constructively engaging much more with a wider range of stakeholders, in particular the food industry, retail, and the catering sector [99]. The difficulty of developing a comprehensive policy response and integrated package of strategies is not restricted to NCDs alone, and has previously been observed in an in-depth analysis of high-burden countries for child malnutrition [100]. We also note that various countries have developed strategies to reduce total fat intake, despite convincing evidence that it is the reduction of saturated and trans-fatty acids in particular, and not total fat intake, that is effective to address NCDs [101]. Most strategies encountered in the policy documents focused on consumers and aimed to prevent NCDs through awareness creation, education (i.e., labeling), or changing individuals' behavior. The traditional approach to addressing lifestyle changes in individuals has met with very limited success. It is widely accepted that the environmental context drives individual diets and lifestyle [102] and that programs need to incorporate environmental determinants (i.e., the quantity, quality, or price of dietary choices, or the built environment for physical activity) in order to be effective. Such policy measures, in particular those addressing the private sector, were poorly elaborated in the policy documents [103]. A key issue is the actual implementation of policy measures in relation to what was articulated in the documents. The findings of this review indicate that few LMICs have made significant steps in the development of a comprehensive set of strategies to address NCDs. Although an in-depth evaluation of actual implementation, effects, and resources allocated has not been opportune to date, we hope that our findings provide baseline data and encourage countries to develop monitoring and evaluation mechanisms to assess policy response in due time. Documenting the effectiveness of population-based NCD prevention policies will be a critical factor of success to ensure effective action in LMICs [4]. For this review, we were able to assess documents in all languages received. Because of language constraints, however, two of the documents [74],[87] were coded by only one researcher. To assess the content of the policy of Iran, we relied on translations by experienced senior Iranian researchers. All other policy documents were obtained in Spanish, Portuguese, French, or English and were analyzed accordingly by the research team. For China and the Russian Federation, appropriate English versions of the policies were obtained from the Chinese Centers for Disease Control and the United States Department of Agriculture, respectively. Despite indications of availability of relevant policies in the European region [26], language limitations did not allow us to search the websites of a number of countries such as Azerbaijan, Belarus, and the Russian Federation. The restriction of our review to only national policies presents a number of limitations. The mere presence or absence of policies or strategies for NCDs in a policy document does not necessarily reflect concrete action. Conversely, nutritional interventions have been implemented in some countries without a policy being developed and published [104]. In addition, this review assessed the contents of the policy documents as they were published and did not capture local or regional activities, or initiatives that emerged after the publication of the policies. The findings from a survey in countries with a high burden of NCDs, such as Thailand and South Africa, illustrate this discrepancy [23]. The contents might have been modified over time in response to new scientific findings, emerging nutritional challenges, or changes in the countries' priorities [91]. In addition, it is important to point out that we extracted only actions that explicitly referred to one of the risk factors analyzed. Generic statements such as “development of food-based dietary guidelines” or “establishment of fiscal measures for a healthy diet” were hence not coded. The present review shows that the policy response to address current NCD challenges through diet and physical inactivity in LMICs is inadequate since endorsement of the Global Strategy on Diet, Physical Activity and Health [20]. LMICs urgently need to scale up interventions and develop integrated policies that address various risk factors for NCD prevention through multi-stakeholder collaboration and cross-sector involvement. Clear and prioritized actions are needed to harness the NCD epidemic. Such actions need to be documented in policy documents that are publicly available to share lessons learned, promote engagement with the stakeholders, and stimulate accountability and leadership in the fight against the burden of NCDs in LMICs. The establishment of an open-access and publicly accessible database of policy documents with regular systematic reviews of policy development might prove to be an incentive in this regard.

Childhood obesity and the built environment.
Maida Galvez, Meghan Pearl, Irene H. Yen (2010)
Neighborhood factors are increasingly examined for their role in the childhood obesity epidemic. Whereas studies on the impacts of neighborhood factors on adult obesity are relatively common, studies examining these same factors on childhood obesity are far fewer. Using the Ecological Systems Theory (EST) as a model, we sought to examine the strength of the literature with respect to neighborhood factors as outlined in EST. This includes factors related to the family and the school, which are embedded in larger social contexts of the community and society. These factors are often referred to in the literature as the 'built environment' which encompasses the entire range of structural elements in a residential setting including, for example, housing mix, transportation networks, public resources, and presence of sidewalks or trails. Whereas progress has been made with respect to the body of evidence supporting the role of neighborhood factors on childhood obesity and obesity-related behaviors, much work remains to be done to enhance our understanding of neighborhood level factors. As the body of evidence grows, these studies will inform multilevel interventions which are urgently needed to tackle the growing epidemic of childhood obesity in the US.
