The adoption of "evidence-based" or "evidence-informed" practice has been explored in many sectors and professions. ISHN has suggested often that the process of "mobilizing" (ie. actually using) knowledge is far more complex, chaotic, competitive and challenging than the logical models that are often presented. An article in Issue #4, 2015 of Journal of Evidence-Informed Social Work leads us in a similar direction when it presents a systematic review of social workers' evidence-based practice orientation, attitudes, and implementation. the authors suggest that "the authors aim to synthesise research findings exploring social workers' EBP orientation, attitudes, adoption, knowledge, skills, and perceived EBP barriers and facilitators. Numerous challenges to EBP implementation were identified, including: time management, research accessibility, and misperceptions of the role of evidence in decision making. Colleagues, supervisors, perceived experts, organizational culture, and tailored training were important for social workers' dissemination and utilization of evidence. Social workers may prefer more conversational, face-to-face methods of research dissemination." In other words, social workers, like health professionals and educatotrs like the research knowledge to be filtered through their own professional experiences and those of colleagues. They also prefer to to come in personal bite-sized bits from trusted colleagues and through their own systems, trusted channels. Read more >> (An item from the ISHN Member information service)

An article in Issue #3, 2015 of Population and Development Review describes how the World Health Organization (WHO) has used the issue of Non-Communicable Diseases (NCD's) as a focus and thereby helped to re-establish its credibility. The authors describe how WHO has used NCD's in an opportunistic manner. "Chronic noncommunicable diseases (NCDs) in low- and middle-income countries have recently provoked a surge of public interest. This article examines the policy literature—notably the archives and publications of the World Health Organization (WHO), which has dominated this field—to analyze the emergence and consolidation of this new agenda. Starting with programs to control cardiovascular disease in the 1970s, experts from Eastern and Western Europe had by the late 1980s consolidated a program for the prevention of NCD risk factors at the WHO. NCDs remained a relatively minor concern until the collaboration of World Bank health economists with WHO epidemiologists led to the Global Burden of Disease study that provided an “evidentiary breakthrough” for NCD activism by quantifying the extent of the problem. Soon after, WHO itself, facing severe criticism, underwent major reform. NCD advocacy contributed to revitalizing WHO's normative and coordinative functions. By leading a growing advocacy coalition, within which The Lancet played a key role, WHO established itself as a leading institution in this domain. However, ever-widening concern with NCDs has not yet led to major reallocation of funding in favor of NCD programs in the developing world." This strategy of health organizations jumping onto an emerging issue to secure resources and credibility is not unique to WHO. The question which needs to be answered is what happens when interest/support in that particular issue wanes? Read more >> (An item from the ISHN Member information service)
A special issue (#3, 2015) of the Journal of Children's Services examines how families and schools can work together to enhance educational and other outcomes. Two of the articles report on the effect of two major parent education/training programs; The Incredible Years and Families and Schools Together. Both of these programs are multi-intervention in nature, seeking to influence parent and child behaviours as well as conditions in the school and home. This comprehensive approach is compatible with larger school health promotion programs. The special issue also contains three research reviews. The first is an assessment of systematic reviews on parent-school bullying prevention programs. The second is an extended review of the impact of parent-school programs on educational achievement. The third is similar but uses a meta-analysis methodology. Read more >> (An item from the ISHN Member information service)
This blog continues to suggest a new approach to school health promotion and social development that does not dump the responsibilities of other professionals on teachers because of scarce resources in those other sectors. An editorial in Issue #3, 2015 of Social Work Research is an example of this trend to always view the teacher as a resource for a function that should be carried out by others. In this case, it is the function of securing mental health services for students, a task that should be assigned to school social workers, school psychologists or school nurses. "...it would be appropriate to discuss another challenge for urban schools, to better serve the unmet behavioral health needs of African American students. Teachers are an untapped resource in addressing the unmet mental health services needs of inner-city African American children. They often have the primary responsibility for identifying mental disorders in children and bridging students with problems to needed services. What are the factors associated with teachers' decisions to refer or not refer African American children for mental health services? What are the relationships between organizational factors, community factors, teachers' knowledge, and teachers' decisions for services referral? And what are the pathways to services for African American children? Increased scholarship investigating these relationships as another variable for interventions to effectively affect services for African American students is very important." There is no debate about the unmet need and even about the teachers role in identifying and refering students. The debate is about asking teachers to walk down the complicated and poorly funded "pathways" to securing the service. Ironically, an article in the same issue explored the use of social workers as such navigators and concluded that they were being under-used.

The UN General Assembly adopted the 2030 global development goals that will replace the previous Millennium Development Goals that concluded in 2015 at its meeting in New York. The news clippings this week capture some of that activity. The items we identified this week include the summit web site, several different access points, and more. Education is one of the 17 goals and was highlighted as being central to the success of all of the goals by the UN Secretary General in one news release. Another important news release came from several UN agencies, with a call for better integration between health and education. ISHN and its partners in our global dialogue, ASCD and Education International are very pleased to see this call. There are several other news release, statements and world leaders available from the items we identified this week. Read more >> (An item from the ISHN Member information service)
Commission on Ferguson USA Racism/Unrest Calls for Whole Child, Safe, Healthy, Community Schools9/30/2015 This week saw several news stories on the report of the Commission investigating the shooting of black teenager Michael Brown. The report of the commission, which includes the word "unflinching", recommends that a whole child approach and a revamped school system be included in a focus on youth at the center of the reforms. The school-related actions include; reforming school discipline, providing support services to disadvantaged youth, ending childhood hunger, and several other measures to promote wellness and personal development. Note: In 2010 ISHN worked with the Community Schools movement to develop a consensus statement/adapted approach to schools in disadvantaged communities in high resource countries. Racism and other forms of discrimination were included as one of the many challenges but we also worked from a strength-based viewpoint and identified over 20 programs that can be part of these efforts. We released it at the 2010 School Health Symposium in Geneva. Read more >> (An item from the ISHN Member information service)
A research review identified in this week's news/reports describes how cooperation between governments, municipalities and school boards is required if schools are going to be able to get beyond projects and "passive" responses to this intervention that has the most impact on daily physical actiivity among students. Without this type of cooperation, it is unlikely that exhortations to parents to forget about those challenges (and sometimes legal charges) and let their children freely walk to school. This evidence review was done for the education ministry of Ontario, Canada. It assessed the impact of adopting active school transportation policies within governments, municipalities and school boards. "The searches of health, education and sports databases identified 608 abstracts. Governments have increased their focus on increasing both active travel to school and physical activity. Many US states have policies. that may impact active travel in school in addition to the Safe Routes to School SRTS program. Six categories of state statutory (legislative) and administrative (regulatory) laws were examined (minimum busing distance, hazardous route exemptions to the distance requirement (hazards, traffic or unsafe crossing), sidewalk requirements near schools, crossing guards, traffic control measures (e.g., speed bumps) and speed zones around schools." All of these measures had some effect. "The odds of having walking school bus (WSB) program is significantly associated with district policies and a state law requiring crossing guards. However, none of the other state law variables were strongly associated with a WSB program. There is limited literature that assesses the impact of municipalities adopting active transportation policies, which is often associated with millions of funding invested. Further research is needed." Read more >> (An item from the ISHN Member information service)
Two articles in Volume 82, 2015 of Accident Analysis & Prevention examine the impact of signs and other traffic control measures to improve driving behaviour in school zones. One article suggests that "Based on the models of human information processing, if a driver observes too many of the same signs, he or she may no longer pay attention to those signs. In the case of school zones, this expected effect may lead to non-compliance to posted speeds, negatively impacting safety around nearby schools. Results found a significant effect of sign saturation on vehicle speed, compliance, and accident frequency." The second article suggests that "The effectiveness and performance of traffic control devices in school zones have been impacted significantly by many factors, such as driver behavioral attributes, roadway geometric features, environmental characteristics, weather and visibility conditions, region-wide traffic regulations and policies, control modes, etc. When deploying traffic control devices in school zones, efforts are needed to clarify: (1) whether traffic control device installation is warranted; and (2) whether other device effectively complements this traffic control device and strengthens its effectiveness.The experimental tests and analysis results reveal that the appropriateness of the installation of certain traffic control devices can be statistically verified by using a model described in the article.

A special section on the student effects on teacher behaviors and attitudes appears in in Issue #5, 2015 of International Journal of Behavioral Development. One of the articles explains the idea. "Classroom research has typically focused on the role of teaching practices and the quality of instruction in children’s academic performance, motivation and adjustment—in other words, classroom interactions initiated by the teacher. The present article presents a model of classroom interactions initiated by the child, that is, the notion that a child’s characteristics and active efforts may evoke different instructional patterns and responses among teachers." Other articles report that; (1) Elementary school teachers adapt their instructional support according to students’ academic skills, (2) children’s reading skills and interests affect teacher perceptions of children’s skills and individualized support, (3) there are reciprocal relations between student–teacher conflict, children’s social skills and externalizing behavior, (4) focusing on teacher–student interactions in a coaching program can eliminate the negative impact of students’ disruptive behavior on teacher perceptions and (5) children evoke similar affective and instructional responses from their teachers and mothers.

Much attention on actual activity levels in PE classes and other parts of the school day has been generated by concerns about childhood obesity/overweight. Ironically, this focus on quantity (which is being proved over-reaching in terms of weight loss). Further, it may detract from the more important function of teaching movement skills in PE classes. An article in Issue #2, 2015 of Asia-Pacific Journal of Health, Sport and Physical Education suggests "moving back to movement" as a core purpose of PE. "This paper provides a greater insight into why human motion has high value and should be utilised more in advocacy and implementation in health and education, particularly school health and physical education. It will illuminate where the impact of human motion is taken for granted and undervalued. It will also reveal compelling research findings from a range of disciplines not traditionally included in the field that support motion's value to human existence across the lifespan. An article in September 2015 Issue of Sports Medicine calls for further investigation. "Evidence indicates that motor competence is positively associated with perceived competence and multiple aspects of health (i.e., physical activity, cardiorespiratory fitness, muscular strength, muscular endurance, and a healthy weight status. Thus, it is an appropriate time to examine published data that directly or indirectly relate to specific pathways noted in the conceptual model linking movement skills with these fitness factors."

An article in Issue #5, 2015 of Journal of Science and Medicine in Sport reports a systematic review of physical activity and cognition in adolescents. The results are described as positive but, in fact, the reviews appear to be mixed. "The purpose is to perform a systematic review of the evidence on the associations between physical activity and cognition by differentiating between academic and cognitive performance measures.A total of 20 articles met the inclusion criteria, 2 of them analyzed both cognitive and academic performance . Four articles (18%) found no association between physical activity and academic performance, 11 (50%) found positive association and one showed negative association (5%). Five articles (23%) found positive association between physical activity and cognitive performance and one showed negative association (5%). The findings of these studies show that cognitive performance is associated with vigorous physical activity and that academic performance is related to general physical activity, but mainly in girls". The authors suggest that "Results of the review support that physical activity is associated with cognition, but more research is needed to clarify the role of sex, intensity and type of physical activity and some psychological variables of this association." While there is likely little doubt, based on common sense, that we are all alert and functioning better when we are active, especially immediately after taking an activity break, the real question is how much activity makes a difference for young people (who are usually quite active on average) and how much impact is created from increased moderate activity achieved in schools (which other studies often measure in marginal gains of a few minutes in multiple activities such as recess, walking to school, increased activity in PE classes, PA breaks in classrooms etc. Read more >> (An item from the ISHN Member information service)
As the realization that physical activity alone does not significantly affect body weight or obesity gradually grows in the research, policy-making and practice, it is important to note that there are other real and important physical benefits from increased levels of activity. An article in the September 2015 Issue of International Journal of Behavioral Nutrition and Physical Activity highlights some of those benefits. "Physical activity (PA), weight-bearing exercises (WBE) and muscle strength contribute to skeletal development, while sedentary behaviour (SB) adversely affects bone health. Previous studies examined the isolated effect of PA, SB or muscle strength on bone health, which was usually assessed by x-ray methods, in children. Little is known about the combined effects of these factors on bone stiffness (SI) assessed by quantitative ultrasound. We investigated the joint association of PA, SB and muscle strength on SI in children. This study suggests that already an additional 10 min/day of MPA or VPA or the participation in WBE may result in a relevant increase in SI in children, taking muscle strength and SB into account. Our results support the importance of assessing accelerometer-based PA in large-scale studies. This may be important when deriving dose–response relationships between PA and bone health in children."

Several articles in Issue #5, 2015 of Youth & Society examine how school are organized, the norms and attitudes of teachers and their goals concerning student well-being have an impact on student health and social development. The first article notes that "There are few areas of school organization that reflect more dissatisfaction than how to structure the education of adolescents in the middle grades." A study from the Netherlands reported on how ethnic minority students in vocational high schools were often expelled from those schools to attend "rebound" schools. A third article reported that the number of middle and high schools in a community were predictive of higher levels of drug crime in New Mexico, USA. A fourth article made the argument for schools incorporating student well-being as an essential indicator of their effectiveness as a school. A Quebec study reported that ethnicity and teacher-perceived signs of disadvantage in kindergarten predicted that visible minority children were far less likely to have a positive relationship with their Grade Four teachers.

Two articles in Volume 53, 2015 of Social Science Research examine residential mobility during adolescence and housing instability. The first article reports that "Controlling for major predictors of housing mobility, students experiencing at least one move over a 12-month period have a roughly 50% decreased likelihood of obtaining a high school diploma by the age of 25. These associations are identified regardless of whether students move to a poorer or less-poor neighborhood". The second study "investigated the longitudinal effects of family structure changes and housing instability in adolescence on functioning in the transition to adulthood. Findings suggested housing mobility in adolescence predicted poorer functioning across outcomes in young adulthood, and youth living in multigenerational homes exhibited greater likelihood to be arrested than adolescents in single-generation homes. However, neither family structure changes nor its interaction with residential instability or ethnicity related to young adult outcomes. Read more>> (An item from the ISHN Member information service)
Adolescent substance use following participation in a universal drug prevention program is reported in an article in Issue #3, 2015 of Substance Abuse. "The study examined whether adolescents receiving a universal, school based, drug prevention program in Grade 7 varied, by student profile, in substance use behaviors post program implementation. Profiles were a function of recall of program receipt and substance use at baseline." Students who had no baseline substance use and had program recall were significantly less likely to use substances. For other students, including those who had no recall of the program but were not using at the start of the program and those who were using before participating in the program, the universal program had no impact.

Several articles in Issue #8-9, 2015 of Substance Use & Misuse are part of a special Issue describing progress (and not) in substance abuse. The title of the issue says it well "Fifty Years Later: Ongoing Flaws and Unfinished Business". The articles include some great insights into the debates, many ongoing, within this filed. They include a discussion of the politics in dropping the term "addiction" and turning to problematic or misuse; the failure to address discrimination as a cause of substance abuse; the clever marketing that underlies "evidence-based practices" and how the concept of "gateway drug" needs to be retired. Another article likes drug use by young people in Hong Kong to the profound economic and social changes that have occurred there in the past five decades. One not to be missed is an article discussing how negative (focus on risk and problems) and positive (focus on assets and youth development) models in adolescent substance abuse prevention are found wanting. The over reliance on RCT studies as the "gold standard" in knowledge development is also debated. Another article describes the ongoing challenges associated with implementation and maintenance of effective programs. Other deal with context, the challenges of integrated programming, evidence-based vs local programs, and community-school cooperation. n brief, the special issues captures much of the recent history and challenges in substance abuse prevention but it also offers insight into prevention and promotion more generally.

(An item from the ISHN Member information service) Two articles in Volume 183, 2015 of Journal of Affective Disorders report on the use of the Delphi method (used to develop consensus) to list and assess the value of interventions to reduce the risk of adolescent depression and on parenting strategies to reduce childhood depression and anxiety. The first article used a literature search to identify 194 potential interventions. "These were presented over three questionnaire rounds to panels of 32 international research and practice experts and 49 consumer advocates, who rated the preventive importance of each recommendation and the feasibility of their implementation by adolescents. 145 strategies were endorsed as likely to be helpful in reducing adolescents׳ risk of developing depression by ≥80% of both panels. Endorsed strategies included messages on mental fitness, personal identity, life skills, healthy relationships, healthy lifestyles, and recreation and leisure. " The second article used a literature search identified 289 recommendations for parents which were then presented to a panel of 44 international experts over three survey rounds, who rated their preventive importance. "171 strategies were endorsed as important or essential for preventing childhood depression or anxiety disorders by ≥90% of the panel." Some researchers contributed to both articles. The ISHN web site (www.schools-for-all.org) uses a similar combination of research-based evidence and the views of experienced practitioners, descition-makers and advocates and publishes the content in a Wikipedia style web site.

Multiple Intelligences: A Part of Curriculum Design in Health-Personal-Social Development Education9/21/2015 (An item from the ISHN Member information service) Most of the discussion and debates about curriculum design in health-personal-social development education has revolved around teaching knowledge (facts) and/or skills. In fact, the design and delivery of HPSD education is far more sophisticated than these two elements. They include attitudes, health beliefs/self-efficacy, normative beliefs, functional knowledge, behavioural intentions, perceptions of risk and more. An article in Issue #3, 2015 of Global Health Promotion reminds us yet another element, multiple intelligences (MI). The concept of MI recognizes that students learn in a variety of ways, through verbal, logical, spatial, bodily, interpersonal, naturalistic and existentialist intelligences. The article reports on a Nigeria study where a programme of drug education based on the Multiple Intelligences Teaching Approach (MITA) was developed. "An experimental group was taught using this programme while a control group was taught using the same programme but developed based on the Traditional Teaching Approach. Pupils taught with the MITA acquired more drug refusal skills than those taught with the Traditional Teaching Approach." Note: The ISHN description of HPSD education can be found here. Read more>>
(An item from the ISHN Member information service) This blog advocates use of ecological analysis and action (comprising an ecological approach) so that the complex, inter-related factors in the real world can be considered when identifying and implementing interventions to influence both individual behaviours as well as conditions that influence those behaviours. An article in Issue #3, 2015 of Health Promotion International got our attention when it called for more attention to " time, a dimension beyond the socio-ecological model, is a critical factor of families' busy lives". We have no quarrel with the argument presented in the article. "Physical activity and healthy eating have long been promoted as key strategies in tackling the ‘wicked problem’ of obesity. Both practices are assumed to go hand-in-hand, but whether one dominates the other has largely remained unexamined. ". The study conducted 47 family interviews as part of a mixed methods study examining environmental influences on youth obesity. "Time pressure to meet the demands associated with scheduled physical activity for youth was the dominant theme across interviews from all neighborhoods. Physical activity and healthy eating were valued differently, with greater value placed on physical activity than healthy eating. The pressure to engage youth in organized physical activity appeared to outweigh the importance of healthy eating, which led to neglecting family meals at home and consuming fast food and take out options. Our findings further reinforce the need to move beyond the socio-ecological model to integrate critical dimensions such as ‘time’, to allow for a more nuanced understanding of contemporary healthy living." Our quarrel rests with the interpretation of the ecological model. Surely that is the purpose of examining the ecology of the situation, including all relevant factors such as time, transportation, economics and much more. Note: The ISHN definition of an ecological approach can be found here. Read more>>
(An item from the ISHN Member information service) Many of the national and provincial mental health strategies announced in recent years have included schools as a primary component, with teachers being critical, especially their "mental health literacy". An article in Issue #3, 2015 of School Mental Health reports on a small scale study that describes teacher perceptions of their role(s). It is noteworthy that teacher competence in MH is only one of the six factors identified as barriers by teachers. "This paper explores the teacher role in inter-professional collaboration in mental health promotion and identifies teachers’ perceived challenges to collaborative work in this field. Data are derived from a mixed method design, with three focus group interviews (n = 15) and survey research (n = 771) conducted with Norwegian K-12 teachers. The findings show that teachers perceive their gatekeeping role to be prominent, in that they are front line professionals to identify students’ mental health problems and, if necessary, make referrals to mental health services. However, teachers realize that mental health promotion encompasses more than the assessment of difficulties, and they call for more support and information through inter-professional collaboration in order to extend their engagement in student mental health beyond the gatekeeping role. Based on this, six main challenges to inter-professional collaboration are identified. These are the challenges of: (1) communication and confidentiality, (2) time constraints, (3) contextual presence and understanding, (4) cross-systems contact, (5) school leadership and (6) teacher competence in mental health."

(An item from the ISHN Member information service) With the global community now debating the purposes and aspects of quality education as part of the 2015-30 Social Development Goals development, an article in Issue #3, 2015 of Comparative Education Review makes a timely point about the lack of a connection between increased student testing and subsequent economic growth. "This article considers the growth of the international testing regime. It discusses sources of growth and empirically examines two related sets of issues: (1) the stability of countries’ achievement scores, and (2) the influence of those national scores on subsequent economic development over different time lags. The article suggests that stability over time and across tests has historically been weak but is increasing in the post-1990 era. In addition, the analysis finds little evidence of macro-level effects of test score performance on subsequent economic growth. Read more>>
(An item from the ISHN Member information service) An article in the August 2015 Issue of Social Indicators reports on the well-being of children in south-east Asia. We agree with the author's assertion that such reports are too often biased towards western Europe and North America. "Much progress has been made recently in expanding the literature on international comparison of children’s wellbeing. Nevertheless, most studies are skewed toward western or European countries, with the Asian nations rarely included. The purpose of this study is to fill the gap by conducting an exploratory comparison of children’s wellbeing in East and Southeast Asian countries. A multidimensional approach is adopted by analyzing material wellbeing, health, educational wellbeing, behavior, environment, and psychosocial wellbeing, together with their associated components and indicators. All countries are ranked according to their overall child wellbeing indices, including and excluding the dimension of psychosocial wellbeing. The results show that Japan, Korea, and Singapore perform best while Malaysia, Vietnam, Thailand, and Indonesia do less well in terms of children’s wellbeing. Various issues, including the paucity of data, are discussed as items to be considered in the agenda for future research." ISHN also agrees with the suggestion in the article that an agenda for research and knowledge development on child and adolescent health should be developed within the region. Read more>>
(An item from the ISHN Member information service) An article in Issue #4, 2015 of Public Administration Review helps us to understand one aspect of the decision-making processes that occur in professional bureaucracies such as health, education or other ministries/systems. The article examines advice networks and the role that structures, internal competition and Individual attributes play in shaping those networks and the advice. The authors summarize their work: "Interpersonal networks are increasingly important for organizational learning and performance. However, little is known about how these networks emerge. In this article, exponential random graph models are employed to explore the underlying processes of advice network formation in 15 organizations. The author examines the influence of (1) structural effects (reciprocity, transitivity, multiplexity), (2) actor attribute effects (job function, tenure, education, self-efficacy), and (3) peer competition. Results suggest that employees rely more on reciprocity, closure, and similarity in job function than on peer expertise or status when seeking advice. In addition, employees who perceive greater levels of competition with peers are significantly less likely to both seek and provide advice. As public organizations look to private sector strategies that promote internal competition to improve efficiency and accountability, public managers need to be aware of the negative implications those strategies can have on interpersonal networks and organizational learning." In school health promotion and social development we have traditionally ignored the systems above schools, even though we know that eventually and inevitably, educators and nurses in schools will need to report back and ask for resources from these agencies, ministries and systems.

(An item from the ISHN Member information service) ISHN has been discussing the limits systematic review in this blog. An article in Issue #3, 2015 of Evidence & Policy extends our skepticism by examining how various "evidence tools (health impact assessments, systematic reviews and cost-benefit studies) are used, misused and misinterpreted in the real world of public decision-making. The authors conclude that "Each has been promoted as a means of synthesising evidence for policy makers but little is known about policy actors' experiences of them. Employing a literature review and 69 interviews, we offer a critical analysis of their role in policy debates, arguing that their utility lies primarily in their symbolic value as markers of good decision making." Not having access to the full text of that article, we did find a very similar version online that includes this statement "‘evidence tools’ can be important means of supporting policy decisions because they appear to be objective and credible (or at least more objective and credible than single studies may be). In addition, the interviewee suggests that ‘evidence tools’ employing quantitative data and providing clear and simple ‘answers’ to policy questions represent ‘gold dust’ to policymakers, who are often desperate for some sense of certainty within complex (and often contested) debates. " They go on to say that " All this leads us to conclude that ‘evidence tools’ represent means of drawing policymakers’ attention to particular kinds of evidence (and, implicitly, away from other kinds). As such, they might best be understood as ‘research-informed advocacy tools’ constructed and employed by actors (researchers using their black magic) working to inform the policy process. Read more>>
(An item from the ISHN Member information service) A Cochrane Review published in the August 2015 issue of the newsletter reports that there is little evidence that multiple lifestyle interventions can reduce cardiovascular risks in low and middle income countries. The authors report that "Due to the limited evidence currently available, we can draw no conclusions as to the effectiveness of multiple risk factor interventions on combined CVD events and mortality. There is some evidence that multiple risk factor interventions may lower blood pressure levels, body mass index and waist circumference in populations in LMIC settings at high risk of hypertension and diabetes. There was considerable heterogeneity between the trials, the trials were small, and at some risk of bias." Even more startling was the statement in the introduction of the article that suggests there is limited evidence supporting such multiple lifestyle interventions in high income countries as well.
