Fluoridation cessation and oral health equity: a 7-year post-cessation study of Grade 2 schoolchildren in Alberta, Canada.

OBJECTIVE: Community water fluoridation, because of its universal scope and passive mechanism of uptake, is one component of a multifaceted approach to promoting equity in dental health. The objective of this study was to examine social inequities in children's dental health in the Canadian cities of Calgary (fluoridation cessation in 2011) and Edmonton (still fluoridated). METHODS: We analyzed data from surveys of population-based samples of Grade 2 (approx. age 7) children in Calgary in 2009/2010 (pre-cessation; n=557) and in both Calgary and Edmonton in 2013/2014 (Calgary, n=3230; Edmonton, n=2304) and 2018/2019 (Calgary, n=2649; Edmonton, n=2600) (post-cessation). We estimated associations between several socioeconomic indicators and dental caries indicators (i.e., dental caries experience [deft, DMFT] and untreated decay in two or more teeth [untreated decay]) using zero-inflated Poisson, binary logistic regression, and the concentration index of inequality. We compared those associations over time (between survey waves) and between cities at post-cessation. RESULTS: Persistent social inequities in deft and untreated decay were evident; for example, having no dental insurance was significantly associated with higher odds of untreated decay across city and survey wave. In most (but not all) cases, differences between cities and survey waves were consistent with an adverse effect of fluoridation cessation on dental health inequities. For example, the association between no dental insurance and higher odds of untreated decay in Calgary was greater in 2018/2019 (later post-cessation) than in 2009/2010 (pre-cessation; odds ratio [OR] for comparison of coefficients = 1.89 [1.36-2.63], p<0.001) and 2013/2014 (early post-cessation; OR for comparison of coefficients = 1.67 [1.22-2.28], p=0.001); that same association in 2018/2019 was greater in Calgary (fluoridation cessation) than in Edmonton (still fluoridated) (OR for comparison of coefficients = 1.44 [1.03-2.02], p=0.033). CONCLUSION: Social inequities in dental caries were present in both Calgary and Edmonton. Those inequities tended to be worse in Calgary where fluoridation was ceased. Our findings may be relevant to other settings where income inequality is high, dental services are costly, and dental public health infrastructure is limited.

RéSUMé: OBJECTIF: En raison de sa portée universelle et de son mécanisme de réception passif, la fluoration de l'eau des communautés s'inscrit dans une démarche multidimensionnelle de promotion de l'équité en santé dentaire. Notre étude visait à examiner les iniquités sociales en santé dentaire chez les enfants dans les villes canadiennes de Calgary (où la fluoration a cessé en 2011) et d'Edmonton (où l'eau est encore enrichie en fluor). MéTHODE: Nous avons analysé les données d'enquêtes menées auprès d'échantillons populationnels d'élèves de 2e année (environ 7 ans) à Calgary en 2009-2010 (avant l'arrêt; n = 557), et à Calgary et Edmonton en 2013-2014 (Calgary, n = 3 230; Edmonton, n = 2 304) et en 2018-2019 (Calgary, n = 2 649; Edmonton, n = 2 600) (après l'arrêt). Nous avons estimé les associations entre plusieurs indicateurs socioéconomiques et indicateurs de caries dentaires (c.-à-d. l'expérience de caries dentaires [dceo, DCMO] et de dégradation non traitée dans deux dents ou plus [dégradation non traitée]) à l'aide de la régression de Poisson à surreprésentation de zéros, de la régression logistique binaire et de l'indice de concentration des inégalités. Nous avons comparé ces associations dans le temps (entre les cycles de l'enquête) et entre les deux villes après l'arrêt de la fluoration. RéSULTATS: Des iniquités sociales persistantes selon l'indice dceo [dents cariées, extraites et obturées] et la dégradation non traitée étaient manifestes; par exemple, l'absence d'assurance dentaire présentait une corrélation significative avec une probabilité accrue de dégradation non traitée d'une ville à l'autre et d'un cycle à l'autre de l'enquête. Dans la plupart des cas (mais pas tous), les différences entre les villes et entre les cycles de l'enquête correspondaient à un effet indésirable de l'arrêt de la fluoration sur les iniquités en santé dentaire. Par exemple, l'association entre l'absence d'assurance dentaire et la probabilité accrue de dégradation non traitée à Calgary était plus importante en 2018-2019 (longtemps après l'arrêt) qu'en 2009-2010 (avant l'arrêt; rapport de cotes [RC] pour comparaison des coefficients = 1,89 [1,36-2,63], p < 0,001) et qu'en 2013-2014 (peu après l'arrêt; RC pour comparaison des coefficients = 1,67 [1,22-2,28], p = 0,001); cette même association en 2018-2019 était plus importante à Calgary (où la fluoration a cessé) qu'à Edmonton (où l'eau est encore enrichie en fluor) (RC pour comparaison des coefficients = 1,44 [1,03-2,02], p = 0,033). CONCLUSION: Des iniquités sociales relativement aux caries dentaires étaient présentes tant à Calgary qu'à Edmonton. Ces iniquités avaient tendance à être plus importantes à Calgary, où la fluoration a cessé. Nos constatations pourraient être pertinentes dans les autres endroits où l'inégalité des revenus est élevée, où les soins dentaires coûtent cher et où les infrastructures en santé publique dentaire sont limitées.

Survey Research on Health Inequalities: Exploring the Availability of Indicators of Multiple Forms of Capital in Canadian Datasets.

Objective: Much of the extensive quantitative research linking socio-economic position (SEP) and health utilizes three common indicators: income, occupation and education. Existing survey data may enable researchers to include indicators of additional forms of capital in their analyses, permitting more nuanced consideration of the relationship between SEP and health. Our objective was to identify the breadth of survey questions related to economic, cultural, and social capital available through Statistics Canada surveys, and the extent to which those surveys also include health measures. Methods: We compiled a list of all population-based Statistics Canada surveys, and developed a broad list of potential indicators of forms of capital. We systematically searched the surveys for those indicators and health measures, analyzing their co-occurrence. Results: Traditional SEP indicators were present in 73% of surveys containing health measures, while additional indicators of social and cultural capital were available in 57%. Conclusion: Existing national survey data represent an under-exploited opportunity for research examining the relationship between various forms of capital and health in Canada. Future empirical explorations of these data could enrich our theoretical understanding of health inequities.

Trends in Socioeconomic Inequities in Diet Quality between 2004 and 2015 among a Nationally Representative Sample of Children in Canada.

BACKGROUND: Dietary inequities in childhood may shape dietary and health inequities across the life course. Quantifying the magnitude and direction of trends in absolute and relative gaps and gradients in diet quality according to multiple indicators of socioeconomic position (SEP) can inform strategies to narrow these inequities. OBJECTIVES: We examined trends in absolute and relative gaps and gradients in diet quality between 2004 and 2015 according to 3 indicators of SEP among a nationally representative sample of children in Canada. METHODS: Data from children (aged 2-17 y; n = 18,670) who participated in the cross-sectional Canadian Community Health Survey-Nutrition in 2004 or 2015 were analyzed. SEP was based on total household income, household educational attainment, and neighborhood deprivation. Dietary intake data from 1 interviewer-administered 24-h dietary recall were used to derive a Healthy Eating Index-2015 (HEI-2015) score for each participant as a measure of diet quality. Inequities in diet quality were quantified using 4 indices: absolute and relative gaps (between highest and lowest SEP) and absolute (Slope Index of Inequality) and relative gradients (Relative Index of Inequality). Overall and age-stratified multivariable linear regression and generalized linear models examined trends in HEI-2015 scores between 2004 and 2015. RESULTS: Although mean HEI-2015 total scores improved from 52.3 to 57.3 (maximum 100 points; P < 0.001), absolute and relative gaps and gradients in diet quality remained mostly stable for all 3 SEP indicators. However, among children aged 6-11 y, absolute and relative gradients in diet quality according to household educational attainment and neighborhood deprivation widened. CONCLUSIONS: The diet quality of children in Canada was poor and inequitably patterned in 2004 and 2015. Although mean diet quality improved between 2004 and 2015, absolute and relative gaps and gradients in diet quality persisted, with some evidence of widening absolute and relative gradients among 6- to 11-y-olds.

Socioeconomic inequities in diet quality among a nationally representative sample of adults living in Canada: an analysis of trends between 2004 and 2015.

BACKGROUND: Socioeconomic inequities in diet quality are stable or widening in the United States; however, these trends have not been well characterized in other nations. Moreover, purpose-developed indices of inequities that can provide a more comprehensive and precise perspective of trends in absolute and relative dietary gaps and gradients using multiple indicators of socioeconomic position (SEP) have not yet been used, and can inform strategies to narrow dietary inequities. OBJECTIVES: We quantified nationally representative trends in absolute and relative gaps and gradients in diet quality between 2004 and 2015 according to 3 indicators of SEP among adults in Canada. METHODS: Adults (≥18 y old) who participated in the nationally representative, cross-sectional Canadian Community Health Survey-Nutrition in 2004 (n = 20,880) or 2015 (n = 13,970) were included. SEP was classified using household income (quintiles), education (5 categories), and neighborhood deprivation (quintiles). Dietary intake data from 24-h recalls were used to derive Healthy Eating Index-2015 (HEI-2015) scores. Dietary inequities were quantified using absolute and relative gaps (between the most and least disadvantaged) and absolute [Slope Index of Inequality (SII)] and relative gradients (Relative Index of Inequality). Overall and sex-stratified multivariable linear regression and generalized linear models examined trends in HEI-2015 scores between 2004 and 2015. RESULTS: Mean HEI-2015 scores improved from 55.3 to 59.0 (maximum: 100); however, these trends were not consistently equitable. Whereas inequities in HEI-2015 scores were stable in the total population and in females, the absolute gap [from 1.60 (95% CI: 0.09, 3.10) to 4.27 (95% CI: 2.20, 6.34)] and gradient [from SII = 2.09 (95% CI: 0.45, 3.73) to SII = 4.84 (95% CI: 2.49, 7.20)] in HEI-2015 scores for household income, and the absolute gradient for education [from SII = 8.06 (95% CI: 6.41, 9.71) to SII = 10.52 (95% CI: 8.73, 12.31)], increased in males. CONCLUSIONS: Absolute and relative gaps and gradients in overall diet quality remained stable or widened between 2004 and 2015 among adults in Canada.

The Equity and Effectiveness of Achieving Canada's Voluntary Sodium Reduction Guidance Targets: A Modelling Study Using the 2015 Canadian Community Health Survey-Nutrition.

Background: High sodium intake is a leading modifiable risk factor for cardiovascular diseases. This study estimated full compliance to Canada's voluntary sodium reduction guidance (SRG) targets on social inequities and population sodium intake. Methods: We conducted a modeling study using n = 19,645, 24 h dietary recalls (Canadians ≥ 2 years) from the 2015 Canadian Community Health Survey-Nutrition (2015 CCHS-N). Multivariable linear regressions were used to estimate mean sodium intake in measured (in the 2015 CCHS-N) and modelled (achieving SRG targets) scenarios across education, income and food security. The percentage of Canadians with sodium intakes above chronic disease risk reduction (CDRR) thresholds was estimated using the US National Cancer Institute (NCI) method. Results: In children aged 2-8, achieving SRG targets reduced mean sodium intake differences between food secure and insecure households from 271 mg/day (95%CI: 75,468) to 83 mg/day (95%CI: -45,212); a finding consistent across education and income. Mean sodium intake inequities between low and high education households were eliminated for females aged 9-18 (96 mg/day, 95%CI: -149,341) and adults aged 19 and older (males: 148 mg/day, 95%CI: -30,327; female: -45 mg/day, 95%CI: -141,51). Despite these declines (after achieving the SRG targets) the majority of Canadians' are above the CDRR thresholds. Conclusion: Achieving SRG targets would eliminate social inequities in sodium intake and reduce population sodium intake overall; however, additional interventions are required to reach recommended sodium levels.

Developing a framework to inform scale-up success for population health interventions: a critical interpretive synthesis of the literature.

Background: Population health interventions (PHIs) have the potential to improve the health of large populations by systematically addressing underlying conditions of poor health outcomes (i.e., social determinants of health) and reducing health inequities. Scaling-up may be one means of enhancing the impact of effective PHIs. However, not all scale-up attempts have been successful. In an attempt to help guide the process of successful scale-up of a PHI, we look to the organizational readiness for change theory for a new perspective on how we may better understand the scale-up pathway. Using the change theory, our goal was to develop the foundations of an evidence-based, theory-informed framework for a PHI, through a critical examination of various PHI scale-up experiences documented in the literature. Methods: We conducted a multi-step, critical interpretive synthesis (CIS) to gather and examine insights from scale-up experiences detailed in peer-reviewed and grey literatures, with a focus on PHIs from a variety of global settings. The CIS included iterative cycles of systematic searching, sampling, data extraction, critiquing, interpreting, coding, reflecting, and synthesizing. Theories relevant to innovations, complexity, and organizational readiness guided our analysis and synthesis. Results: We retained and examined twenty different PHI scale-up experiences, which were extracted from 77 documents (47 peer-reviewed, 30 grey literature) published between 1995 and 2013. Overall, we identified three phases (i.e., Groundwork, Implementing Scale-up, and Sustaining Scale-up), 11 actions, and four key components (i.e., PHI, context, capacity, stakeholders) pertinent to the scale-up process. Our guiding theories provided explanatory power to various aspects of the scale-up process and to scale-up success, and an alternative perspective to the assessment of scale-up readiness for a PHI. Conclusion: Our synthesis provided the foundations of the Scale-up Readiness Assessment Framework. Our theoretically-informed and rigorous synthesis methodology permitted identification of disparate processes involved in the successful scale-up of a PHI. Our findings complement the guidance and resources currently available, and offer an added perspective to assessing scale-up readiness for a PHI.

Why public health matters today and tomorrow: the role of applied public health research.

Public health is critical to a healthy, fair, and sustainable society. Realizing this vision requires imagining a public health community that can maintain its foundational core while adapting and responding to contemporary imperatives such as entrenched inequities and ecological degradation. In this commentary, we reflect on what tomorrow's public health might look like, from the point of view of our collective experiences as researchers in Canada who are part of an Applied Public Health Chairs program designed to support "innovative population health research that improves health equity for citizens in Canada and around the world." We view applied public health research as sitting at the intersection of core principles for population and public health: namely sustainability, equity, and effectiveness. We further identify three attributes of a robust applied public health research community that we argue are necessary to permit contribution to those principles: researcher autonomy, sustained intersectoral research capacity, and a critical perspective on the research-practice-policy interface. Our intention is to catalyze further discussion and debate about why and how public health matters today and tomorrow, and the role of applied public health research therein.

In defense of a population-level approach to prevention: why public health matters today.

A focus on populations, and a corresponding population-level approach to intervention, is a foundation of public health and is one reason why public health matters today. Yet, there are indications that this foundation is being challenged. In some policy and practice domains, and alongside growing concern about the social determinants of health and health equity, there has been a shift from a population-level or universal approach to intervention, to a targeted approach focusing on those experiencing social or economic vulnerability. More than 30 years ago, Geoffrey Rose articulated strengths and limitations of population-level and high-risk approaches to prevention. In light of a strong analogy between "high risk" and "targeted" approaches, it seems timely, in a forum on why public health matters today, to revisit Rose's points. Focusing on points of overlap between strengths and limitations of the two approaches as described in public health (population-level; high-risk) and social policy (universal; targeted), I illustrate strengths of a population-level approach from the point of view of health equity. Although different circumstances call for different intervention approaches, recent discourse about the weakening of public health suggests that there is value in discussing foundations of the field, such as the population-level approach, that we as a community may wish to defend.

Socioeconomic Disadvantage across the Life Course Is Associated with Diet Quality in Young Adulthood.

Socioeconomic position (SEP) is a key determinant of diet quality across the life course. Young adulthood is a unique period of transition where dietary inequities between groups with lower and higher SEP may widen. This study investigated associations between SEP in both childhood and young adulthood and diet quality in young adulthood. Data from 1949 Canadian young adults aged 18⁻30 who participated in the Canada Food Study were analyzed. Healthy Eating Index⁻2015 (HEI-2015) scores were calculated based on one 24-hour dietary recall. Childhood and young adult SEP were represented by self-report of participants' parent(s)' and their own highest educational level, respectively. Linear regression was used to examine associations between childhood and adult SEP and adult HEI-2015 score. Mediation analyses examined whether adult SEP mediated the relationship between childhood SEP and adult HEI-2015 score. Lower SEPs in childhood and adulthood were each associated with lower HEI-2015 scores in young adulthood. Adult SEP mediated up to 13.0% of the association between childhood SEP and adult HEI-2015 scores. Study findings provide support for key life course hypotheses and suggest latent, pathway, and cumulative effects of SEP across the early life course in shaping the socioeconomic patterning of diet quality in young adulthood.

Identifying and critically examining government legislation relevant to children's dental caries in Calgary, Alberta, Canada: a health inequities lens.

OBJECTIVES: Children's dental caries is an important and urgent public health concern that is largely preventable. Using a social equity framework, our objectives were to identify and critically examine government legislation relevant to the issue of children's dental health in Calgary, Alberta, Canada. METHODS: We conducted a systematic, gray literature search of federal, provincial (Alberta), and municipal (Calgary) statutes and bylaws related to children's dental caries, through the relevant law databases. Eligibility criteria were applied for document screening and selection. Data extraction and synthesis pertained to objectives of the legislation (policy task), relevant agent or actor (level of government), and upstream or downstream focus, in terms of potential impact on social inequities in health. RESULTS: Legislation (n = 114) was retrieved and grouped into eight policy tasks. Most legislation fit under the policy tasks: protection of public safety and health promotion (n = 40) and benefits and compensation (n = 27). Federal and provincial governments have greater involvement in children's dental caries than municipal (Calgary) government. The majority of legislation was classified as upstream in orientation (e.g., improving living and working conditions; macro-level policies). CONCLUSIONS: Analysis of legislation relevant to children's dental caries reveals policies that are more often upstream in nature, and unsurprisingly are multijurisdictional. Despite this, there remains a high prevalence and inequitable distribution of children's dental caries in Canada. This suggests that the nature of upstream involvement and fragmented government involvement is ineffective in tackling this pervasive and urgent public health issue. Implications for children's dental health are discussed.

Is there more to the equation? Weight bias and the costs of obesity.

The costs of obesity have been well studied, with estimates in Canada reaching $7.1 billion annually. These estimates fuel public and professional discourse about obesity as an "epidemic" with substantial economic and public health consequences. However, cost estimates for obesity thus far have neglected to consider a critical variable: weight bias (i.e., negative bias towards individuals based on their body weight). In this commentary, we propose that some costs currently attributed to obesity may be partly or fully attributable to weight bias. Taking a burden of illness approach, we show that data derived from a purposeful literature search, provided as proof of concept, support the notion that weight bias may be an important variable to consider when calculating obesity-related costs. We propose that future research on costs of obesity should consider weight bias, with goals of achieving more accurate cost attributions and identifying appropriate leverage points for interventions to improve well-being of the population.

Ethnic disparities in children's oral health: findings from a population-based survey of grade 1 and 2 schoolchildren in Alberta, Canada.

BACKGROUND: Although oral health has improved remarkably in recent decades, not all populations have benefited equally. Ethnic identity, and in particular visible minority status, has been identified as an important risk factor for poor oral health. Canadian research on ethnic disparities in oral health is extremely limited. The aim of this study was to examine ethnic disparities in oral health outcomes and to assess the extent to which ethnic disparities could be accounted for by demographic, socioeconomic and caries-related behavioral factors, among a population-based sample of grade 1 and 2 schoolchildren (age range: 5-8 years) in Alberta, Canada. METHODS: A dental survey (administered during 2013-14) included a mouth examination and parent questionnaire. Oral health outcomes included: 1) percentage of children with dental caries; 2) number of decayed, extracted/missing (due to caries) and filled teeth; 3) percentage of children with two or more teeth with untreated caries; and 4) percentage of children with parental-ratings of fair or poor oral health. We used multivariable regression analysis to examine ethnic disparities in oral health, adjusting for demographic, socioeconomic and caries-related behavioral variables. RESULTS: We observed significant ethnic disparities in children's oral health. Most visible minority groups, particularly Filipino and Arab, as well as Indigenous children, were more likely to have worse oral health than White populations. In particular, Filipino children had an almost 5-fold higher odds of having severe untreated dental problems (2 or more teeth with untreated caries) than White children. Adjustment for demographic, socioeconomic, and caries-related behavior variables attenuated but did not eliminate ethnic disparities in oral health, with the exception of Latin American children whose outcomes did not differ significantly from White populations after adjustment. CONCLUSIONS: Significant ethnic disparities in oral health exist in Alberta, Canada, even when adjusting for demographic, socioeconomic and caries-related behavioral factors, with Filipino, Arab, and Indigenous children being the most affected.

Interactions between Neighbourhood Urban Form and Socioeconomic Status and Their Associations with Anthropometric Measurements in Canadian Adults.

Neighbourhood-level socioeconomic composition and built context are correlates of weight-related behaviours. We investigated the relations between objective measures of neighbourhood design and socioeconomic status (SES) and their interaction, in relation to self-reported waist circumference (WC), waist-to-hip ratio, and body mass index (BMI) in a sample of Canadian adults (n = 851 from 12 Calgary neighbourhoods). WC and BMI were higher among residents of disadvantaged neighbourhoods, independent of neighbourhood design (grid, warped grid, and curvilinear street patterns) and individual-level characteristics (sex, age, education, income, dog ownership, marital status, number of dependents, motor vehicle access, smoking, sleep, mental health, physical health, and past attempts to modify bodyweight). The association between neighbourhood-level SES and WC was modified by neighbourhood design; WC was higher in disadvantaged-curvilinear neighbourhoods and lower in advantaged-grid neighbourhoods. Policies making less obesogenic neighbourhoods affordable to low socioeconomic households and that improve the supportiveness for behaviours leading to healthy weight in low socioeconomic neighbourhoods are necessary.

Taking stock of the social determinants of health: A scoping review.

BACKGROUND: In recent decades, the social determinants of health (SDOH) has gained increasing prominence as a foundational concept for population and public health in academic literature and policy documents, internationally. However, alongside its widespread dissemination, and in light of multiple conceptual models, lists, and frameworks, some dilution and confusion is apparent. This scoping review represents an attempt to take stock of SDOH literature in the context of contemporary population and public health. METHODS: We conducted a scoping review to synthesize and map SDOH literature, informed by the methods of Arksey and O'Malley (2005). We searched 5 academic and 3 grey literature databases for "social determinants of health" and "population health" or "public health" or "health promotion," published 2004-2014. We also conducted a search on "inequity" or "inequality" or "disparity" or "social gradient" and "Canad*" to ensure that we captured articles where this language was used to discuss the SDOH. We included articles that discussed SDOH in depth, either explicitly or in implicit but nuanced ways. We hand-searched reference lists to further identify relevant articles. FINDINGS: Our synthesis of 108 articles showed wide variation by study setting, target audience, and geographic scope, with most articles published in an academic setting, by Canadian authors, for policy-maker audiences. SDOH were communicated by authors as a list, model, or story; each with strengths and weaknesses. Thematic analysis identified one theme: health equity as an overarching and binding concept to the SDOH. Health equity was understood in different ways with implications for action on the SDOH. CONCLUSIONS: Among the vast SDOH literature, there is a need to identify and clearly articulate the essence and implications of the SDOH concept. We recommend that authors be intentional in their efforts to present and discuss SDOH to ensure that they speak to its foundational concept of health equity.

Population-level interventions in government jurisdictions for dietary sodium reduction: a Cochrane Review.

Background: Worldwide, excessive salt consumption is common and is a leading cause of high blood pressure. Our objectives were to assess the overall and differential impact (by social and economic indicators) of population-level interventions for dietary sodium reduction in government jurisdictions worldwide. Methods: This is a Cochrane systematic review. We searched nine peer-reviewed databases, seven grey literature resources and contacted national programme leaders. We appraised studies using an adapted version of the Cochrane risk of bias tool. To assess impact, we computed the mean change in salt intake (g/day) from before to after intervention. Results: Fifteen initiatives met the inclusion criteria and 10 provided sufficient data for quantitative analysis of impact. Of these, five showed a mean decrease in salt intake from before to after intervention including: China, Finland (Kuopio area), France, Ireland and the UK. When the sample was constrained to the seven initiatives that were multicomponent and incorporated activities of a structural nature (e.g. procurement policy), most (4/7) showed a mean decrease in salt intake. A reduction in salt intake was more apparent among men than women. There was insufficient information to assess differential impact by other social and economic axes. Although many initiatives had methodological strengths, all scored as having a high risk of bias reflecting the observational design. Study heterogeneity was high, reflecting different contexts and initiative characteristics. Conclusions: Population-level dietary sodium reduction initiatives have the potential to reduce dietary salt intake, especially if they are multicomponent and incorporate intervention activities of a structural nature. It is important to consider data infrastructure to permit monitoring of these initiatives.
