IntroductionFood systems can shape dietary behaviour and obesity outcomes in complex ways. Qualitative systems mapping using causal loop diagrams (CLDs) can depict how people understand the complex dynamics, inter-relationships and feedback characteristic of food systems in ways that can support policy planning and action. To date, there has been no attempt to review this literature. The objectives of this review are to scope the extent and nature of studies using qualitative systems mapping to facilitate the development of CLDs by stakeholders to understand food environments, including settings and populations represented, key findings and the methodological processes employed. It also seeks to identify gaps in knowledge and implications for policy and practice.Methods and analysisThis protocol describes a scoping review guided by the Joanna Briggs Institute manual, the framework by Khalil and colleagues and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews checklist reporting guidelines. A search strategy was iteratively developed with two academic librarians and the research team. This strategy will be used to search six databases, including Ovid MEDLINE, Embase, EmCare, Web of Science, Scopus and ProQuest Central. Identified citations will be screened by two independent reviewers; first, by title and abstract, and then full-text articles to identify papers eligible for inclusion. The reference lists of included studies and relevant systematic reviews will be searched to identify other papers eligible for inclusion. Two reviewers will extract information from all included studies and summarise the findings descriptively and numerically.Ethics and disseminationThe scoping review will provide an overview of how CLDs developed by stakeholders have been elicited to understand food environments, diet and obesity, the insights gained and how the CLDs have been used. It will also highlight gaps in knowledge and implications for policy and practice. The review will be disseminated through publication in an academic journal and conference presentations.

To understand differences in financial performance, quality performance, supplemental benefits provision, and enrollee composition between integrated and non-integrated plans in the Medicare Advantage (MA) program.We used data from the Center for Medicare and Medicaid Services for 2015-2017. We included 156 integrated MA plans (31 unique contracts) and 2096 non-integrated MA plans (392 unique contracts).We estimated linear probably models for financial performance, quality performance, supplemental benefits provision, and enrollee composition with state fixed effects and contract random effects. We adjusted for county-level market structure-related factors, cost-related factors, and demand-related factors. Our primary independent variable was an indicator of plan-provider integration.Integrated MA plans were associated with $19.4 (95% CI: 9.2, 29.7) and $16.6 (95% CI: 10.3, 22.9) higher Part C and Part D monthly premiums, but were associated with higher star quality ratings. There were no significant differences in revenues and plan payments per enrollee between integrated and non-integrated MA plans. Integrated MA plans were associated with $40.5 (95% CI: -54.0, -26.9) lower non-claims costs than non-integrated MA plans. There was limited evidence that integrated MA plans provided more generous supplemental benefits than non-integrated MA plans. Enrollment rates in integrated MA plans were particularly low among socially marginalized groups (3.4 [95% CI: -5.9, -1.0], 4.7 [95% CI: -8.5, -0.9], and 4.4 [95% CI: -6.4, -2.4] percentage points lower among non-Hispanic Black, Medicare-Medicaid dual eligible, and the disabled).Our findings suggest that integrated MA plans may achieve higher efficiency and quality, but these benefits may not be experienced by all beneficiaries due to disparities in enrollment. As these models continue to spread, it is critical to develop policies to ensure that MA enrollees have equal access to integrated plans.

Objective:To examine food and beverage purchasing patterns across formal and informal outlets among Mexican households’ and explore differences by urbanicity and income.Design:Cross-sectional study of a nationally representative sample of households. We calculated the proportion of total food and beverage expenditure in each household by food outlet type overall and by urbanicity and income. We defined informal outlets as those which are not registered or regulated by tax and fiscal laws. Since some of the outlets within community food environments do not fall in clear categories, we defined a continuum from formal to informal outlets, adding mixed outlets as a category.Setting:Mexico.Participants:Mexican households (n 74 203) from the 2018 National Income and Expenditure Survey.Results:Of the total food and beverage purchases, outlets within the formal food sector (i.e. supermarkets and convenience stores) accounted for 15 % of the purchases, 13 % of purchases occurred in outlets within the informal food sector (i.e. street markets, street vendors and acquaintances) and 70 % in fiscally mixed outlets (i.e. small neighbourhood stores, specialty stores and public markets). Across levels of urbanicity and income, most food and beverage purchases occurred in mixed outlets. Also, purchases in informal and mixed outlets decreased as levels of urbanicity and income increased. In contrast to informal outlets, purchases in formal outlets were most likely from richer households and living in larger sized cities.Conclusions:Understanding where Mexican households shop for food is relevant to create tailored interventions according to food outlet type, accounting for regulatory and governance structures.

Background Price promotions on sugar-sweetened beverages (SSBs) are commonly used by retailers to provide economic incentives for purchasing. Surprisingly, there is a lack of high-quality articles that examine the frequency and magnitude of sugary beverage discounting and consumer responses to discounts. The objective of this study is to quantify the association between exposure to price discounts and SSB purchases. Methods This cross-sectional study linked 2016 SSB consumption data from a U.S. household consumer panel (analytic sample N = 11,299 households) and weekly prices at stores where they shopped. We derived percent of the time SSBs were discounted (annual promotion frequency) and the amount of the discount (annual promotion magnitude) and assessed their association with household annual per capita SSB purchase ounces. Linear regression models adjusted for household size, income per capita, age, education, presence of children, race, occupation, region, and urbanicity. We also evaluated whether the association between promotion and purchase varied by socioeconomic status and race subgroups. Data were analyzed in 2019–2020. Results On average, households were exposed to SSBs price promotions 44% of the time. A 10-percentage point increase in annual SSB promotion frequency was associated with 13.7% increase in annual per capita purchasing (P P P > 0.2). Conclusions More frequent and deeper price promotion was associated with higher annual per capita SSB purchases. Restricting SSB price promotions may be effective at reducing SSB consumption.

BackgroundDiabetes prevalence continues to increase in urban areas of low-income and middle-income countries (LMIC). Evidence from high-income countries suggests an inverse association between educational attainment and diabetes, but research in LMIC is limited. We investigated educational differences in diabetes prevalence across 232 Latin American (LA) cities, and the extent to which these inequities vary across countries/cities and are modified by city socioeconomic factors.MethodsUsing harmonised health survey and census data for 110 498 city dwellers from eight LA countries, we estimated the association between education and diabetes. We considered effect modification by city Social Environment Index (SEI) as a proxy for city-level development using multilevel models, considering heterogeneity by sex and country.ResultsIn women, there was an inverse dose–response relationship between education and diabetes (OR: 0.80 per level increase in education, 95% CI 0.75 to 0.85), consistent across countries and not modified by SEI. In men, Argentina, Brazil, Colombia, Chile and Mexico showed an inverse association (pooled OR: 0.92; 95% CI 0.86 to 0.99). Peru, Panama and El Salvador showed a positive relationship (pooled OR 1.24; 95% CI 1.04 to 1.49). For men, these associations were further modified by city-SEI: in countries with an inverse association, it became stronger as city-SEI increased. In countries where the association was positive, it became weaker as city-SEI increased.ConclusionSocial inequities in diabetes inequalities increase as cities develop. To achieve non-communicable disease-related sustainable development goals in LMIC, there is an urgent need to develop policies aimed at reducing these educational inequities.

Rapid growth of Medicare Advantage (MA) plans has the potential to change clinical practice for both MA and fee-for-service (FFS) beneficiaries, particularly for high-need, high-cost beneficiaries with multiple chronic conditions or a costly single condition. We assessed whether MA growth from 2010 to 2017 spilled over to county-level per capita spending, emergency department visits, and readmission rates among FFS beneficiaries, and how much this varied by the comorbidity burden of the beneficiary. We also examined whether the association between MA growth and per capita spending in FFS varied in beneficiaries with specific chronic conditions. MA growth was associated with decreased FFS spending and emergency department visits only among beneficiaries with six or more chronic conditions. MA growth was associated with decreased FFS spending among beneficiaries with 11 of the 20 chronic conditions. This suggests that MA growth may drive improvements in efficiency of health care delivery for high-need, high-cost beneficiaries.

BackgroundDisparities in access to care persist for Latino youth born in the United States (US). The association of maternal characteristics, such as maternal citizenship status and insurance coverage, on youth health insurance coverage is unclear and is important to examine given the recent sociopolitical shifts occurring in the US.MethodsWe analyzed pooled cross-sectional data from the 2010–2018 National Health Interview Survey to examine the association of Latina maternal citizenship status on maternal insurance coverage status and youth uninsurance among US-born Latino youth. Our study sample consisted of 15,912 US-born Latino youth (ages ResultsOverall, 7% of US-born Latino youth were uninsured. Just 6% of youth with US-born mothers were uninsured compared to almost 10% of those with noncitizen mothers. Over 18% of youth with uninsured mothers were uninsured compared to 2.2% among youth with mothers who had private insurance coverage. Compared to both US-born and naturalized citizen Latina mothers, noncitizen Latina mothers had 4.75 times the odds of reporting being uninsured. Once adjusted for predisposing, enabling, and need factors, maternal uninsurance was strongly associated with youth uninsurance and maternal citizenship was weakly associated with youth uninsurance among US-born Latino youth.ConclusionMaternal citizenship was associated with both maternal uninsurance and youth uninsurance among US-born Latino youth. Federal- and state-level health policymaking should apply a two-generational approach to ensure that mothers of children are offered affordable health insurance coverage, regardless of their citizenship status, thus reducing uninsurance among US-born Latino youth.

Health insurance literacy helps individuals make informed choices. However, evidence suggests that Medicare beneficiaries experience low health insurance literacy, leading to high-cost or poor-quality coverage choices.To examine how health insurance literacy was associated with coverage choices between traditional Medicare (TM) and Medicare Advantage (MA), as well as within MA.This cross-sectional study included 6627 TM and MA enrollees, using data from the 2015-2016 Medicare Current Beneficiary Survey. Data analyses were conducted between May 1 and June 30, 2021.Three self-reported measures of health insurance literacy (presence of information to make an informed comparison, ease in reviewing and comparing coverage options, and annual review and comparison of coverage options).Enrollment in TM vs MA and enrollment in an MA plan with different characteristics (star rating, monthly plan premium, in-network maximum out-of-pocket limit, plan type, and provision of supplemental benefits).We included 6627 Medicare beneficiaries (3578 women [54.0%]; mean [SD] age, 75.13 [7.12] years). A total of 77 individuals were Asian (1.2%), 696 were Black (10.5%), 488 were Hispanic (7.4%), 5277 were non-Hispanic White (79.6%), and 225 (3.4%) were single races not of Hispanic origin (including American Indian or Alaska Native and Native Hawaiian) or were 2 or more races. Medicare Advantage enrollment was higher among individuals with higher health insurance literacy than those with lower health insurance literacy, especially for those who reviewed or compared coverage options annually than among those who did not (38.0%; 95% CI, 36.0%-40.1% vs 27.8%; 95% CI, 25.8%-29.7%). Among MA beneficiaries, those who reviewed or compared coverage options annually were more likely to enroll in plans with 4 to 4.5 stars and plans with monthly premiums of $1 to $50 by 4.6 percentage points (95% CI, 0.1-9.2 percentage points) and 4.8 percentage points (95% CI, 0.6-9.0 percentage points), respectively. However, enrollment in plans with 5 stars was 3.8 percentage points lower (95% CI, -5.8 to -1.9 percentage points) among individuals who reviewed or compared coverage options annually than among those who did not. Among individuals with low socioeconomic status, the likelihood of reviewing or comparing coverage options annually was lower for those with Medicare and Medicaid dual eligibility than for those without it (odds ratio, 0.79; 95% CI, 0.63-0.99).Results of this study suggest that higher health insurance literacy-particularly, annual review and comparison of coverage choices-is associated with higher MA enrollment and choice of a particular MA plan. Policy makers should develop programs to encourage frequent review and comparison of coverage options for informed decision making.

Objectives:To develop a simulation framework for assessing how combinations of taxes, nutrition warning labels and advertising levels could affect purchasing of ultra-processed foods (UPF) in Latin American countries and to understand whether policies reinforce or reduce pre-existing social disparities in UPF consumption.Design:We developed an agent-based simulation model using international evidence regarding the effect of price, nutrition warning labels and advertising on UPF purchasing.Setting:We estimated policy effects in scenarios representing two stages of the ‘social transition’ in UPF purchasing: (1) a pre-transition scenario, where UPF purchasing is higher among high-income households, similar to patterns in Mexico; and (2) a post-transition scenario where UPF purchasing is highest among low-income households, similar to patterns in Chile.Participants:A population of 1000 individual agents with levels of age, income, educational attainment and UPF purchasing similar to adult women in Mexico.Results:A 20 % tax would decrease purchasing by 24 % relative to baseline in both the pre- and post-transition scenarios, an effect that is similar in magnitude to that of a nutrition warning label policy. A 50 % advertising increase or decrease had a comparatively small effect. Nutrition warning labels were most effective among those with higher levels of educational attainment. Labelling reduced inequities in the pre-transition scenario (i.e. highest UPF purchasing among the highest socio-economic group) but widened inequities in the post-transition scenario.Conclusions:Effective policy levers are available to reduce UPF purchasing, but policymakers should anticipate that equity impacts will differ depending on existing social patterns in UPF purchasing.

BACKGROUND Starting in 2014, the Affordable Care Act mandated that Medicare Advantage (MA) contracts spend at least 85% of total revenue on claims and quality improvement [ie, the medical loss ratio (MLR)] and submit revenue and cost data annually in MLR reports. These reports can improve transparency of the financial performance of MA contracts. However, little is known about revenues and costs of insurers that participate in MA and its impacts on status changes in the following year. OBJECTIVE To characterize revenues and costs of MA contracts in 2014, with a focus on MLRs and gross margins, and to assess heterogeneity in subsequent-year plan renewal and termination rates by gross margins. RESEARCH DESIGN Cross-sectional data from MLR reports submitted in 2014 by MA contracts and from 2015 Part C & D Plan Crosswalk Files regarding plan renewal, termination, and other status changes from 2014 to 2015. SUBJECTS Three hundred eighty-nine MA contracts. MEASURES Primary outcomes are MLRs and gross margins. RESULTS MLRs averaged 93% in 2014; 11% of contracts reported MLRs of at least 100%. Fifty-six percent reported negative margins, or costs that exceeded revenues. Seventeen percent of plans in contracts in the lowest quartile of gross margins were terminated in 2015, compared to under 5% of plans in the highest-margin contracts. CONCLUSIONS In 2014, MA contracts reported MLRs greater than the mandatory minimum of 85%. Gross margins likely contribute to trends in plan and insurer availability. MLR reports from subsequent years can help explain fluctuations in insurers' participation in MA.

BACKGROUND: The aim of the study was to assess the relationship between educational attainment and health care access and use among Mexican-origin populations. METHODS: Data from the 2012 Mexican National Health and Nutrition Study, the 2013 Project Migrante Health Care Access and Utilization Survey, and the 2013–2014 California Health Interview Survey were used to examine educational gradients in health insurance, medical home, and hospitalization among Mexicans in Mexico, northbound, southbound, and deported migrants, and U.S.-and foreign-born Mexican Americans. RESULTS: College graduates had greater odds of being insured relative to those with less than a high school degree among Mexicans (AOR=1.48, p

OBJECTIVES To examine whether enrollment in Medicare Advantage (MA) and fee-for-service traditional Medicare (TM) is differential by food insecurity and then examine differences in health care utilization, financial burden, care satisfaction, and health status between food-insecure enrollees in MA and TM and between food-secure enrollees in MA and TM. STUDY DESIGN We employed a retrospective cohort study design. Using the 2015-2016 Medicare Current Beneficiary Survey, we identified the following 4 mutually exclusive groups: food-insecure enrollees in MA, food-insecure enrollees in TM, food-secure enrollees in MA, and food-secure enrollees in TM. METHODS We used an instrumental variable approach to address endogenous choice between MA and TM. Using a 2-stage least squares regression model, we estimated the adjusted outcomes for each group and differences in the adjusted outcomes between food-insecure enrollees in MA and TM and between food-secure enrollees in MA and TM. RESULTS There were no significant differences in enrollment between MA and TM by food insecurity status. Compared with food-insecure enrollees in TM, food-insecure enrollees in MA had significantly lower health care utilization and financial burden. A similar pattern was observed among food-secure enrollees, but the difference in health care utilization was greater between food-insecure enrollees in MA and TM than between food-secure enrollees in MA and TM. There were no significant differences in care satisfaction and health status between MA and TM. However, food insecurity status did not improve in MA and TM enrollees over time. CONCLUSIONS MA may deliver care more efficiently to food-insecure beneficiaries than TM, but it is not better at reducing food insecurity.

Medicare beneficiaries in rural areas may face challenges to gaining access to care, particularly if enrolled in Medicare Advantage (MA) plans with limited benefits and restrictive provider networks. These barriers to care may, in turn, increase switching to traditional fee-for-service Medicare among rural MA enrollees. Using 2010-16 Medicare Current Beneficiary Survey data, we found that switching from traditional Medicare to Medicare Advantage was uncommon among enrollees, both rural (1.7 percent) and nonrural (2.2 percent). Switching from Medicare Advantage to traditional Medicare was more common in both settings, especially for rural enrollees (10.5 percent) compared with nonrural enrollees (5.0 percent). The differential was even greater among rural enrollees who were high cost or high need. Of eleven care satisfaction variables we examined, dissatisfaction with care access had the strongest association with switching from Medicare Advantage to traditional Medicare among rural enrollees. Our findings point to the importance of developing policies targeted at improving care access for rural MA enrollees.

Cross-impact balance (CIB) analysis leverages expert knowledge pertaining to the nature and strength of relationships between components of a system to identify the most plausible future ‘scenarios’ of the system. These scenarios, also referred to as ‘storylines’, provide qualitative insights into how the state of one factor can either promote or restrict the future state of one or multiple other factors in the system. This paper presents a novel, visually oriented questionnaire developed to elicit expert knowledge about the relationships between key factors in a system, for the purpose of CIB analysis. The questionnaire requires experts to make selections from a series of standardized cause-effect graphical profiles that depict a range of linear and non-linear relationships between factor pairs. The questionnaire and the process of translating the graphical selections into data that can be used for CIB analysis is described using an applied example which focuses on urban health in Latin American cities. • A questionnaire featuring a set of standardized cause-effect profiles was developed. • Cause-effect profiles were used to elicit information about the strength of linear and non-linear bivariate relationships. • The questionnaire represents an intuitive visual means for collecting data required for the conduct of CIB analysis.

Urban health is shaped by a system of factors spanning multiple levels and scales, and through a complex set of interactions. Building on causal loop diagrams developed via several group model building workshops, we apply the cross-impact balance (CIB) method to understand the strength and nature of the relationships between factors in the food and transportation system, and to identify possible future urban health scenarios (i.e., permutations of factor states that impact health in cities). We recruited 16 food and transportation system experts spanning private, academic, non-government, and policy sectors from six Latin American countries to complete an interviewer-assisted questionnaire. The questionnaire, which was pilot tested on six researchers, used a combination of questions and visual prompts to elicit participants’ perceptions about the bivariate relationships between 11 factors in the food and transportation system. Each participant answered questions related to a unique set of relationships within their domain of expertise. Using CIB analysis, we identified 21 plausible future scenarios for the system. In the baseline model, ‘healthy’ scenarios (with low chronic disease, high physical activity, and low consumption of highly processed foods) were characterized by high public transportation subsidies, low car use, high street safety, and high free time, illustrating the links between transportation, free time and dietary behaviors. In analyses of interventions, low car use, high public transport subsidies and high free time were associated with the highest proportion of factors in a healthful state and with high proportions of ‘healthy’ scenarios. High political will for social change also emerged as critically important in promoting healthy systems and urban health outcomes. The CIB method can play a novel role in augmenting understandings of complex urban systems by enabling insights into future scenarios that can be used alongside other approaches to guide urban health policy planning and action., Highlights • We used the CIB method to augment findings from group model building workshops. • The CIB method highlights possible future scenarios to guide health policy planning. • We identified 21 plausible future scenarios for cities in Latin America. • Healthy scenarios featured low car use, high public transport subsidies and safety. • Political will appears critically important in promoting healthy urban scenarios.

Introduction Time spent eating is associated with obesity and diet-related diseases. We examined the association between time adults spent eating, immigrant status, race/ethnicity, and race/ethnicity among adults in the United States. Methods We used multivariate linear regression to analyze a cross-sectional, nationally representative sample of respondents aged 19 years or older (N = 192,486) from the 2016 American Time Use Survey. The outcome measures were time spent per day on primary eating and drinking and secondary eating. The predictors were immigrant status, race/ethnicity, and years spent living in the United States. Results Multivariate adjusted minutes per day spent on primary eating and drinking were 66.4 for noncitizens, 66.5 for naturalized citizens, and 60.1 for US-born individuals. Multivariate adjusted minutes per day spent on secondary eating were 11.1 for noncitizens, 12.2 for naturalized citizens, and 12.9 for US-born individuals. Minutes per day spent on primary eating and drinking for immigrants by length of residence in the United States was 69.7 minutes for 5 years or less of residence, 67.9 minutes for 6 to 10 years of residence, 63.6 minutes for 11 to 15 years of residence, and 63.6 minutes for more than 15 years of residence. Minutes per day spent on secondary eating for immigrants by length of residence was 5.5 minutes for 5 years or less of residence, 9.7 minutes for 6 to 10 years of residence, 8.4 minutes for 11 to 15 years of residence, and 12.6 minutes for more than 15 years of residence. Conclusion Time spent eating varied by immigrant status and length of residence in the United States.

Objective The objective of this study was to analyze new telehealth benefits offered by Medicare Advantage (MA) plans in 2020 and examine plan characteristics associated with the provision of the new telehealth benefits. Research design Using publicly available data from the Centers for Medicare and Medicaid Services, we identified unique MA plans with at least 1 enrollee in January 2020. We examined whether plans offered any new telehealth benefits in 2020, the 20 most common types of telehealth services covered, and cost-sharing. Next, we used multivariable logistic regression to identify associations between offering any telehealth benefits and plan characteristics. We conducted a similar analysis for each of the 3 most commonly covered telehealth services. Results Of 2992 unique MA plans, 58.1% offered new telehealth benefits in 2020. The most frequently covered services were primary care, mental health, and urgent care. Coverage for other types of services was limited. Our multivariable logistic regression showed that offering any new telehealth benefits was not more common among plans in rural areas, but was more likely among national plans, those with a monthly premium, those with >3540 enrollees, and those with a star rating of 4.0-4.5. The new telehealth benefits were less likely to be provided by for-profit plans. Overall, findings remained similar when analyzed according to the type of services. Conclusions MA plans are embracing new telehealth benefits, but there is room for improvement. Policymakers should consider how to accelerate the adoption curve of telehealth in MA plans.

Introduction The objective of this study is to examine how allostatic load, a multidimensional measure of the body's cumulative response to stressors experienced throughout the life course, has changed over time and by age among U.S.- and foreign-born Whites, Blacks, and Latinx. Methods Data were from 26,818 adult participants in the 2005–2018 National Health and Nutrition Examination Survey, a national repeated cross-sectional study. Allostatic load was measured based on 10 indicators of cardiovascular, metabolic, and immunologic risk. The analyses were conducted in March 2020. Results Allostatic load increased over time across all groups. The difference between the first and last survey cycle was greatest among U.S.-born Black women (from 2.74 in 2005–2006 to 3.02 in 2017–2018), U.S.-born Latino men (from 2.69 to 3.09) and foreign-born Latino men (from 2.58 to 2.87). Aging gradients in allostatic load were steepest among foreign-born Blacks of both genders and foreign-born Latina women and flattest among U.S.-born and foreign-born Whites. Conclusions Chronic exposure to stressors leads to an erosion of health that is particularly severe among foreign-born Blacks and Latinx. Policies should seek to reduce exposure to structural and environmental risks and to ensure equitable opportunities to achieve optimal health among racial/ethnic minorities and immigrants.

Background: This paper provides statewide estimates on health care access and utilization patterns and physical and behavioral health by citizenship and documentation status among Latinos in California. Methods: This study used data from the 2011–2015 California Health Interview Survey to examine health care access and utilization and physical and behavioral health among a representative sample of all nonelderly Latino and US-born non-Latino white adults (N=51,386). Multivariable regressions estimated the associations between the dependent measures and citizenship/documentation status among Latinos (US-born, naturalized citizen, green card holder, and undocumented). Results: Adjusted results from multivariable analyses observed worse access and utilization patterns among immigrant Latinos compared with US-born Latinos, with undocumented immigrants using significantly less health care. Undocumented Latinos had lower odds of self-reporting excellent/very good health status compared with US-born Latinos, despite them having lower odds of having several physical and behavioral health outcomes (overweight/obesity, physician-diagnosed hypertension, asthma, self-reported psychological distress, and need for behavioral health services). Among those reporting a need for behavioral health services, access was also worse for undocumented Latinos when compared with US-born Latinos. Conclusions: Patterns of poor health care access and utilization and better physical and behavioral health are observed across the continuum of documentation status, with undocumented immigrants having the worst access and utilization patterns and less disease. Despite fewer reported diagnoses and better mental health, undocumented Latinos reported poorer health status than their US-born counterparts.

Objective To examine whether there have been changes in insurance coverage and health care utilization for youth before and after the national implementation of the Patient Protection and Affordable Care Act (ACA) and to assess whether racial and ethnic inequities have improved. Methods Data are from 64,565 youth (ages 0–17 years) participants in the 2011 to 2015 National Health Interview Survey. We conducted multivariate logistic regression analyses to determine how the period after national implementation of the ACA (years 2011–2013 vs years 2014–2015) was associated with health insurance coverage and utilization of health care services (well-child visits, having visited an emergency department, and having visited a physician, all in the past 12 months), and whether changes over the pre- and post-ACA periods varied according to race and Latino ethnicity. Results The post-ACA period was associated with improvements in insurance coverage and well-child visits for all youth. Latino youth had the largest absolute gain in insurance coverage; however, they continued to have the highest proportion of uninsurance post national ACA implementation. With regard to health care equity, non-Latino black youth were less likely to be uninsured and Latino youth had no significant improvements in insurance coverage relative to non-Latino white youth after national ACA implementation. Inequities in health care utilization for non-Latino black and Latino youth relative to non-Latino white youth did not improve. Conclusions Insurance coverage and well-child visits have significantly improved for all youth since passage of the ACA, but inequities persist, especially for Latino youth.

Policymakers are increasingly proposing sugar-sweetened beverage (SSB) taxes as an evidence-based strategy to reduce chronic disease risk; and local health departments (LHDs) are well-positioned to play a role in SSB policy development and advocacy. However, most SSB tax proposals fail to become law and limited empiric guidance exists to inform advocacy efforts. In June 2016, Philadelphia, Pennsylvania, passed an SSB tax. To identify features of the Philadelphia SSB tax policymaking process that contributed to the proposal's passage. Qualitative case study. Semistructured interviews were conducted with key informants closely involved with the policymaking process. Interviews were audio-recorded and transcribed. Local news media about the SSB tax proposal were analyzed to triangulate interview findings. Analysis was conducted in NVivo 10 using inductive qualitative content analysis. Philadelphia, Pennsylvania, during the SSB tax policymaking in process. Nine key informants (2 city councilpersons, 4 city agency officials, 1 community-based advocate, 1 news reporter, and 1 researcher). The Philadelphia SSB tax proposal was introduced with the explicit goal of financing universal prekindergarten and deliberately not framed as a health intervention. This framing shifted contentious debates about government involvement in individual behavior toward discussions about how to finance universal prekindergarten, a goal for which broad support existed. The LHD played an important role in communicating research evidence about potential health benefits of the SSB tax proposal at the end of the policymaking process. During local SSB tax policy development processes, LHD officials and other advocates should encourage policymakers to design SSB tax policies so that revenue is directed toward community investments for which broad public support exists. When communicating with policymakers and the public, LHDs should consider emphasizing how SSB tax revenue will be used in addition to presenting evidence about the potential health benefits of the SSB tax at the local level.

This cross-sectional study examines the association between quality of care for Latinx youths and the ethnic concordance of the mothers and clinicians., Key Points Question Is maternal-clinician ethnic concordance associated with youth receipt of family-centered care? Findings In this cross-sectional study including 2515 Latinx youths, maternal-clinician Latinx ethnic concordance was found to have had a positive average association with maternal reports of their youths receiving family-centered care, after adjusting for maternal characteristics. Meaning The findings of this study suggest that clinicians from underrepresented minority backgrounds contribute to the attenuation of medical home provision disparities among Latinx youths in the US., Importance Disparities in medical home provisions, including receipt of family-centered care (FCC), have persisted for Latinx youths in the US. Objective To examine the association between maternal-clinician ethnic concordance and receipt of FCC among US-born Latinx youths. Design, Setting, and Participants A cross-sectional secondary analysis of data from the Medical Expenditure Panel Survey from January 1, 2010, to December 31, 2017, was conducted. Data analysis was performed from January 6 to February 3, 2020. Latinx youths (age, ≤17 years) born in the US who had a usual source of care and used care in the past year, their Latina mothers (age, 18-64 years), and youths’ health care clinician characteristics (eg, race, ethnicity, and sex) were evaluated using χ2 tests and propensity-score matching methods. Main Outcomes and Measures Maternal reports on whether their youths’ clinician listened carefully to the parent, explained things in a way the parent could understand, showed respect, and spent enough time with the patient. Results There were 2515 US-born Latinx youths with linked maternal characteristics during the study period; 51.67% (95% CI, 48.87%-54.45%) of the youths were male, mean (SD) age was 8.48 (0.17) years (30.86% [95% CI, 28.39%-33.44%] were between ages 5 and 9 years), 61.53% (95% CI, 57.15%-65.74%) had public insurance coverage, and 39.89% (95% CI, 32.33%-47.89%) had mothers who were ethnically concordant with the youths’ medical care clinician. We found that for youths with maternal-clinician ethnic concordance, the probabilities of reporting FCC were significantly higher than they would have been in the absence of concordance: that the medical care clinician listened carefully to the parent (average treatment effect on the treated [ATET], 5.44%; 95% CI, 2.14%-8.74%), explained things in a way the parent could understand (ATET, 4.82%; 95% CI, 1.60%-8.03%), showed respect for what the parent had to say (ATET, 5.51%; 95% CI, 2.58%-8.45%), and spent enough time with the patient (ATET, 5.28%; 95% CI, 1.68%-8.88%). Conclusions and Relevance Given the increase of Latinx populations and the simultaneous shortage of underrepresented minority health care clinicians, the findings of this study suggest that increasing the number of clinicians from underrepresented minority backgrounds and ethnic-concordant parental-clinician relationships may help reduce disparities in receipt of medical home provision among US-born Latinx youths.

Thank you for the opportunity to respond to the recent letter to the editor regarding our paper “Sugar-Sweetened and Diet Beverage Consumption in Philadelphia One Year after the Beverage Tax” [...]

ObjectivePhiladelphia passed a 1·5-cent-per-ounce sweetened beverage tax (SBT). Revenue will fund 10 000 quality pre-kindergarten slots for poor children. It is imperative to understand how revenue from SBT can be used to fund programmes to address education and other social determinants of health. The objective of the present study was to simulate quality pre-kindergarten attendance, educational achievement and sugar-sweetened beverage (SSB) consumption among Philadelphia children and adolescents under six intervention scenarios: (i) no intervention; (ii) 10 000 additional quality pre-kindergarten slots; (iii) a 1·5-cent-per-ounce SBT; (iv) expanded pre-kindergarten and 1·5-cent-per-ounce SBT; (v) a 3-cent-per-ounce SBT; and (vi) expanded pre-kindergarten and 3-cent-per-ounce SBT.DesignWe used an agent-based model to estimate pre-kindergarten enrolment, educational achievement and SSB consumption under the six policy scenarios. We identified key parameters in the model from the published literature and secondary analyses of the Panel Study of Income Dynamics – Child Development Supplement.SettingPhiladelphia, Pennsylvania, USA.SubjectsPhiladelphia children and adolescents aged 4–18 years.ResultsA 1·5-cents-per-ounce tax would reduce SSB consumption by 1·3 drinks/week among Philadelphia children and adolescents relative to no intervention, with larger effects among children below the poverty level. Quality pre-kindergarten expansion magnifies the effect of the SBT by 8 %, but has the largest effect on moderate-income children just above the poverty level. The SBT and quality pre-kindergarten programme each reduce SSB consumption, but primarily benefit different children and adolescents.ConclusionsPairing an excise tax with a complementary programme to improve a social determinant of health represents a progressive strategy to combat obesity, a disease regressive in its social patterning.

Starting in 2014, the Affordable Care Act mandated that Medicare Advantage (MA) contracts spend at least 85% of total revenue on claims and quality improvement [ie, the medical loss ratio (MLR)] and submit revenue and cost data annually in MLR reports. These reports can improve transparency of the financial performance of MA contracts. However, little is known about revenues and costs of insurers that participate in MA and its impacts on status changes in the following year.To characterize revenues and costs of MA contracts in 2014, with a focus on MLRs and gross margins, and to assess heterogeneity in subsequent-year plan renewal and termination rates by gross margins.Cross-sectional data from MLR reports submitted in 2014 by MA contracts and from 2015 Part CD Plan Crosswalk Files regarding plan renewal, termination, and other status changes from 2014 to 2015.Three hundred eighty-nine MA contracts.Primary outcomes are MLRs and gross margins.MLRs averaged 93% in 2014; 11% of contracts reported MLRs of at least 100%. Fifty-six percent reported negative margins, or costs that exceeded revenues. Seventeen percent of plans in contracts in the lowest quartile of gross margins were terminated in 2015, compared to under 5% of plans in the highest-margin contracts.In 2014, MA contracts reported MLRs greater than the mandatory minimum of 85%. Gross margins likely contribute to trends in plan and insurer availability. MLR reports from subsequent years can help explain fluctuations in insurers' participation in MA.

In January 2017, Philadelphia (Pennsylvania) implemented an excise tax ($ 0.015/ounce) on sugar-sweetened and diet beverages. This study is a general population-based study to report on the longer-term impacts of the tax on within-person changes in consumption 12 months after implementation. A quasi-experimental difference-in-difference design was used to contrast Philadelphia vs. nearby comparison cities (Trenton, New Jersey, Camden, New Jersey, and Wilmington, Delaware) at baseline (December 2016&ndash, January 2017) vs. 12-month follow-up (December 2017&ndash, February 2018). A random-digit-dialing phone survey was administered to a population-based cohort. Analyses assessed changes in 30-day consumption frequency and ounces of sugar-sweetened and diet beverages (and a substitution beverage, bottled water) in the analytic sample (N = 515). After 12 months, relative to the comparison group, Philadelphians were slightly more likely to decrease their frequency of sugar-sweetened beverage consumption (39.2% vs. 33.5%), and slightly less likely to increase their frequency of sugar-sweetened beverage consumption (38.9% vs. 43.0%). The effects of the tax estimated in the adjusted difference-in-difference analysis were very small (for example, changes in monthly sugar-sweetened beverage consumption in Philadelphia relative to comparison cities was &minus, 3.03 times or &minus, 51.65 ounces) and confidence intervals were very wide. Results suggested that, one year after implementation, there was no major overall impact of the tax on general population-level consumption of sugar-sweetened or diet beverages, or bottled water. Future studies should test whether the tax&rsquo, s effect differs in vulnerable sub-populations.

To examine differences in health information seeking between U.S.-born and foreign-born populations in the U.S.Data from 2008 to 2014 from the Health Information National Trends Survey were used in this study (n = 15,249). Bivariate analyses, logistic regression, and predicted probabilities were used to examine health information seeking and sources of health information.Findings demonstrate that 59.3% of the Hispanic foreign-born population reported looking for health information, fewer than other racial/ethnic groups in the sample. Compared with non-Hispanic White, non-Hispanic Black (OR = 0.62) and Hispanic foreign-born individuals (OR = 0.31) were the least likely to use the internet as a first source for health information. Adjustment for language preference explains much of the disparity in health information seeking between the Hispanic foreign-born population and Whites; controlling for nativity, respondents who prefer Spanish have 0.25 the odds of using the internet as a first source of health information compared to those who prefer English.Foreign-born nativity and language preference are significant determinants of health information seeking. Further research is needed to better understand how information seeking patterns can influence health care use, and ultimately health outcomes. To best serve diverse racial and ethnic minority populations, health care systems, health care providers, and public health professionals must provide culturally competent health information resources to strengthen access and use by vulnerable populations, and to ensure that all populations are able to benefit from evolving health information sources in the digital age.

This cross-sectional study uses data from the American Community Survey to examine the association of state-level immigrant integration and criminalization policies and maternal citizenship status with health insurance coverage among US-born Latino youths., Key Points Question Are state-level policies that integrate or criminalize immigrants associated with disparities in youth health insurance coverage by maternal citizenship status? Findings In this cross-sectional study of 226 691 US-born Latino youths, residing in a state with a lower level of immigrant integration policies and a higher level of immigrant criminalization policies was associated with higher uninsurance rates. Uninsurance rates for youths with non–US citizen mothers were higher for those who resided in states with low integration and high criminalization immigrant policies. Meaning State-level immigrant policies may be associated with health care access among US-born Latino youths based on maternal citizenship status, and awareness of these disparities appears to be needed to inform advocacy efforts., Importance The association of state-level immigrant policies with uninsurance among Latino youths remains unknown. Objective To assess the association of state-level immigrant integration and criminalization policies with health insurance coverage among US-born Latino youths by maternal citizenship. Design, Setting, and Participants This cross-sectional study analyzed secondary data from the American Community Survey, January 1, 2016, to December 31, 2018, for US-born Latino youths (age, ≤17 years) and their mothers (age, 18-64 years) as well as state-level indicators of immigrant integration and criminalization policies (in all 50 states and the District of Columbia). Exposures Immigrant integration and criminalization policies. Main Outcomes and Measures The main outcome was maternal reports of youth uninsurance status at the time of the American Community Survey interview. Variation in youth uninsurance by maternal citizenship, state immigrant integration policy context, and state immigrant criminalization policy context were examined. All analyses were conducted with weighted survey data. Results Of the 226 691 US-born Latino youths (115 431 [50.92%] male; mean [SD] age, 7.66 [4.92] years) included in the study, 36.64% (95% CI, 36.21%-36.92%) had noncitizen mothers. Overall, 7.09% (95% CI, 6.78%-7.41%) of noncitizen mothers reported that their youths were uninsured compared with 4.68% (95% CI, 4.49%-4.88%) of citizen mothers. Of uninsured youths who resided in states with a low level of immigrant integration policies, 9.10% (8.22%-10.06%) had noncitizen mothers and 4.75% (95% CI, 4.19%-5.37%) had citizen mothers; of uninsured youths who resided in states with high criminalization policies, 9.37% (95% CI, 8.90%-9.87%) had noncitizen mothers and 5.91% (95% CI, 5.64%-6.20%) had citizen mothers. In states with few immigrant integration policies, the probability of uninsurance among youths with noncitizen mothers was 3.3% (95% CI, 2.3%-4.4%) higher than that among youths with citizen mothers. Among youths with noncitizen mothers, the difference in the probability of uninsurance between those residing in states with a low level vs a high level of immigrant integration policies was 2.1% (95% CI, 0.6%-3.6%). Among youths residing in states with high levels of immigrant criminalization policies, those with noncitizen mothers had a 2.6% (95% CI, 1.9%-3.0%) higher probability of being uninsured compared with those whose mothers were citizens. Among youths with noncitizen mothers, the difference in the probability of uninsurance between those who resided in a state with a low level vs a state with a high level of immigrant criminalization policies was 1.7% (95% CI, 0.7%-2.7%). Conclusions and Relevance The findings of this cross-sectional study suggest that among US-born Latino youths, disparities in uninsurance by maternal citizenship are associated with state-level immigrant integration and criminalization policies and that anti-immigrant policies may be associated with disparities in health care access for US-born Latino youths.

Refereed/Peer-reviewed We conducted a systematic review of studies employing complex systems approaches (i.e., agent based and system dynamics models) to understand drivers of mental health and inform mental health policy. We extracted key data (e.g., purpose, design, data) for each study and provide a narrative synthesis of insights generated across studies. The studies investigated drivers and policy intervention strategies across a diversity of mental health outcomes. Based on these studies and the extant literature, we propose a typology of mental health research and policy areas that may benefit from complex systems approaches.

We discuss the design, implementation, and results of a collaborative process designed to elucidate the complex systems that drive food behaviors, transport, and health in Latin American cities and to build capacity for systems thinking and community-based system dynamics (CBSD) methods among diverse research team members and stakeholders. During three CBSD workshops, 62 stakeholders from 10 Latin American countries identified 98 variables and a series of feedback loops that shape food behaviors, transportation and health, along with 52 policy levers. Our findings suggest that CBSD can engage local stakeholders, help them view problems through the lens of complex systems and use their insights to prioritize research efforts and identify novel solutions that consider mechanisms of complexity., Highlights • CBSD methods can promote systems thinking and help identify policy approaches. • Stakeholders identified 98 variables driving food behaviors and transport in cities. • Balancing and reinforcing feedbacks drive change in food behavior and transport. • Feedback loops can also explain policy responses and lack of policy responses. • Stakeholders identified 52 policies that leverage variables and feedbacks.

Refereed/Peer-reviewed Purpose: To: (1) explore how multi-level factors impact the longitudinal prevalence of depression and alcohol misuse among urban older adults (≥ 65 years), and (2) simulate the impact of alcohol taxation policies and targeted interventions that increase social connectedness among excessive drinkers, socially isolated and depressed older adults; both alone and in combination. Methods: An agent-based model was developed to explore the temporal co-evolution of depression and alcohol misuse prevalence among older adults nested in a spatial network. The model was based on Los Angeles and calibrated longitudinally using data from the Multi-Ethnic Study of Atherosclerosis. Results: Interventions with a social component targeting depressed and socially isolated older adults appeared more effective in curbing depression prevalence than those focused on excessive drinkers. Targeting had similar impacts on alcohol misuse, though the effects were marginal compared to those on depression. Alcohol taxation alone had little impact on either depression or alcohol misuse trajectories. Conclusions: Interventions that improve social connectedness may reduce the prevalence of depression among older adults. Targeting considerations could play an important role in determining the success of such efforts.

Latino youth experience worse access to and utilization of health care compared with non-Latino "white" youth, with inequities persisting following the implementation of the Affordable Care Act (ACA). To better understand these disparities, we examine changes in youth's access and utilization associated with the ACA for different Latino heritage groups relative to whites.We use 6 years (2011-2016) of National Health Interview Survey data to examine Latino youth's insurance coverage and health care utilization by heritage group, nativity, and parental language. The dependent measures of utilization included well-child, emergency department, and physician visits. We used multivariable logistic regression models to estimate the odds of each dependent measure and interacted heritage group and time period [2011-2013 (pre-ACA) versus 2014-2016 (post-ACA)] to examine how changes associated with the ACA varied by group.Insurance coverage and well-child visits improved among youth overall following implementation of the ACA. Although Mexican and Central or South American youth experienced the largest absolute increase in coverage, they still had high levels of uninsurance post-ACA (9.9% and 9.1%, respectively). Disparities in coverage between Puerto Rican and white youth improved, while disparities in well-child visits between Mexican and white youth worsened. Little to no movement was observed in disparities by nativity and parental language.Most disparities in insurance and utilization across Latino heritage groups and white youth persisted post-ACA despite significant gains within groups. Although disparities for Puerto Rican youth have improved, Mexican and Central or South American youth continue to experience disparities.

Objective. To describe food expenditure and consumption of foods prepared away from home among Mexican adults. Materials and methods. Data were from 45 241 adult participants in the National Health and Nutrition Survey 2006,a nationally-representative, cross-sectional survey of Mexican households. Descriptive statistics and multivariable linear and logistic regression were used to assess the relationship between location of residence, educational attainment, socioeconomic status and the following: 1) expenditure on all food and at restaurants, and 2) frequency of consumption of comida corrida or restaurant food and street food. Results. Food expenditure and consumption of food prepared away from home were positively associated with socioeconomicstatus, educational attainment, and urban vs. rural residence (p

ObjectiveInvestments have been made to alter the food environment of neighbourhoods that have a disproportionate number of unhealthy food venues. Corner store conversions are one strategy to increase access to fruits and vegetables (F&V). Although the literature shows modest success, the effectiveness of these interventions remains equivocal. The present paper reports on the evaluation of Proyecto MercadoFRESCO, a corner store conversion intervention in two Latino communities.DesignA repeated cross-sectional design was employed. Data were stratified by intervention arm and bivariate tests assessed changes over time. Logistic and multiple regression models with intervention arm, time and the interaction of intervention and time were conducted. Supplementary analyses account for clustering of patrons within stores and staggering of store conversions.SettingThree stores were converted and five stores served as comparisons in East Los Angeles and Boyle Heights, California, USA.SubjectsStore patrons were interviewed before (n550) and after (n407) the intervention.ResultsRelative to patrons of comparison stores, patrons of intervention stores demonstrated more favourable perceptions of corner stores and increased purchasing of F&V during that store visit. Changes were not detected in store patronage, percentage of weekly dollars spent on food for F&V or daily consumption of F&V.ConclusionsConsistent with some extant food environment literature, findings demonstrate limited effects. Investments should be made in multilevel, comprehensive interventions that target a variety retail food outlets rather than focusing on corner stores exclusively. Complementary policies limiting the availability, affordability and marketing of energy-dense, nutrient-poor foods should also be pursued.

Objectives. We assessed the effect of the new Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) food package, implemented in October 2009, on breastfeeding outcomes among a predominately Latina sample of WIC participants in Los Angeles County, California. Methods. We used data from 5020 WIC participants who were interviewed in a series of repeated cross-sectional surveys conducted in 2005, 2008, and 2011. Participants were randomly selected from Los Angeles County residents who received WIC services during those years. Results. Consistent with the WIC population in Los Angeles, participants were mostly Latina and had low levels of income and education; more than half were foreign-born. We found small but significant increases from pre- to postimplementation of the new WIC food package in prevalence of prenatal intention to breastfeed and breastfeeding initiation, but no changes in any breastfeeding at 3 and 6 months. The prevalence of exclusive breastfeeding at 3 and 6 months roughly doubled, an increase that remained large and significant after adjustment for other factors. Conclusions. The new food package can improve breastfeeding outcomes in a population at high risk for negative breastfeeding outcomes.

Introduction: An increasingly popular strategy to improve the food retail environment and promote healthy eating in low-income and minority communities is the corner store conversion. This approach involves partnering with small ‘corner’ food stores to expand access to high-quality fruits, vegetables, and other healthy foods. Methods: We conducted a structured review of the literature to assess inventories and sales in corner stores, as well as to identify intervention strategies employed by corner store conversions. Results: Our review returned eight descriptive studies that discussed corner store inventories and sales, as well as ten intervention studies discussing six unique corner store conversion interventions in the United States, the Marshall Islands, and Canada. Common intervention strategies included: 1) partnering with an existing store, 2) stocking healthy foods, and 3) social marketing and nutrition education. We summarize each strategy and review the effectiveness of overall corner store conversions at changing peoples’ food purchasing, preparation, and consumption behaviors. Conclusions: Consumption of fresh, healthy, affordable foods could be improved by supporting existing retailers to expand their selection of healthy foods and promoting healthy eating at the neighborhood level. Additional corner store conversions should be conducted to determine the effectiveness and importance of specific intervention strategies.
