Protocol for creating a dataset of U.S. state alcohol-related firearm laws 2000-2022

Firearms are a major source of preventable morbidity and mortality in the United States, contributing to over 48,000 deaths in 2022 and generating societal costs in excess of $500 billion. A body of work has examined the relationship between US state level firearm laws and health outcomes, generally finding that some firearm regulations are associated with lower firearm-related mortality. Alcohol has been identified as an additional risk factor for both homicides and suicide and stronger state alcohol laws have been associated with lower rates of suicide. To date, there are no empirical studies that have investigated the impact of laws over a long period of time that target the intersection of alcohol and firearm. One reason for this may be because there is no existing dataset that includes the range of these state laws over time. This study describes the protocol for collecting, coding and operationalizing these legal data.

An assessment of court fees, surcharges, and penalties for alcohol-impaired driving in five midwestern U.S. states: implications for exacerbating poverty and health inequalities

Driving under the influence (DUI) remains an important threat to public health in the United States, and a substantial literature has evaluated the effectiveness of state-mandated penalties. Researchers have overlooked accelerated use of obscured fees and surcharges levied by local and state court systems added to penalties in the past 15 years. We present data regarding DUI penalties for offenders with a blood alcohol content (BAC of 0.08) and the fees and surcharges attached to them in Minnesota, Illinois, Wisconsin, Michigan, and Iowa, and variation in these within Wisconsin at four BAC levels. In all states, surcharges and fees exceed penalty fines substantially. Variation within Wisconsin is also meaningful. Our data suggest that opaque costs in state court systems add a substantial financial burden to DUI penalties, particularly for those with lower incomes. An appraisal of the deterrent role of these added costs is warranted.

Income determines the impact of cash transfers on HIV/AIDS: cohort study of 22.7 million Brazilians

Living with extremely low-income is an important risk factor for HIV/AIDS and can be mitigated by conditional cash transfers. Using a cohort of 22.7 million low-income individuals during 9 years, we evaluated the effects of the world's largest conditional cash transfer, the Programa Bolsa Família, on HIV/AIDS-related outcomes. Exposure to Programa Bolsa Família was associated with reduced AIDS incidence by 41% (RR:0.59; 95%CI:0.57-0.61), mortality by 39% (RR:0.61; 95%CI:0.57-0.64), and case fatality rates by 25% (RR:0.75; 95%CI:0.66-0.85) in the cohort, and Programa Bolsa Família effects were considerably stronger among individuals of extremely low-income [reduction of 55% for incidence (RR:0.45, 95% CI:0.42-0.47), 54% mortality (RR:0.46, 95% CI:0.42-0.49), and 37% case-fatality (RR:0.63, 95% CI:0.51 -0.76)], decreasing gradually until having no effect in individuals with higher incomes. Similar effects were observed on HIV notification. Programa Bolsa Família impact was also stronger among women and adolescents. Several sensitivity and triangulation analyses demonstrated the robustness of the results. Conditional cash transfers can significantly reduce AIDS morbidity and mortality in extremely vulnerable populations and should be considered an essential intervention to achieve AIDS-related sustainable development goals by 2030.

Modelling HIV/AIDS epidemiological complexity: A scoping review of Agent-Based Models and their application

OBJECTIVE

To end the AIDS epidemic by 2030, despite the increasing poverty and inequalities, policies should be designed to deal with population heterogeneity and environmental changes. Bottom-up designs, such as the Agent-Based Model (ABM), can model these features, dealing with such complexity. HIV/AIDS has a complex dynamic of structural factors, risk behaviors, biomedical characteristics and interventions. All embedded in unequal, stigmatized and heterogeneous social structure. To understand how ABMs can model this complexity, we performed a scoping review of HIV applications, highlighting their potentialities.

METHODS

We searched on PubMed, Web of Science, and Scopus repositories following the PRISMA extension for scoping reviews. Our inclusion criteria were HIV/AIDS studies with an ABM application. We identified the main articles using a local co-citation analysis and categorized the overall literature aims, (sub)populations, regions, and if the papers declared the use of ODD protocol and limitations.

RESULTS

We found 154 articles. We identified eleven main papers, and discussed them using the overall category results. Most studies model Transmission Dynamics (37/154), about Men who have sex with Men (MSM) (41/154), or individuals living in the US or South Africa (84/154). Recent studies applied ABM to model PrEP interventions (17/154) and Racial Disparities (12/154). Only six papers declared the use of ODD Protocol (6/154), and 34/154 didn't mention the study limitations.

CONCLUSIONS

While ABM is among the most sophisticated techniques available to model HIV/AIDS complexity. Their applications are still restricted to some realities. However, researchers are challenged to think about social structure due model characteristics, the inclusion of these features is still restricted to case-specific. Data and computational power availability can enhance this feature providing insightful results.

Socioeconomic, Disease Burden, Physical Functioning, Psychosocial, and Environmental Factors Associated With Mortality Among Older Adults: The Brazilian Longitudinal Study of Ageing (ELSI-Brazil)

OBJECTIVES

There is little nationally representative information about factors associated with longevity among older Brazilians.

METHODS

Baseline survey data from the Brazilian longitudinal Study of Aging (ELSI-Brazil) were linked to vital statistics systems. Mortality rates and life expectancy estimates were calculated and compared to official sources. Cox Proportional Hazards models and Population Attributable Fractions (PAFs) identified significant predictors of mortality. Results: Calculated mortality rates and life expectancy estimates were similar to official statistics for most ages with higher risk of death among older ages, as expected. High School completion, being partnered, and female sex were negatively associated with mortality, while being underweight, previous diagnosis of a chronic condition, having any functional limitations, poor self-rated health, low grip strength, and smoking were all associated with higher mortality risk. Discussion: The ELSI-Brazil study has potential to identify factors associated with longevity and to inform programs and policies designed to enhance healthy aging among older adults in Brazil.

Evolving academic and research partnerships in global health: a capacity-building partnership to assess primary healthcare in the Philippines

Building fair, equitable, and beneficial partnerships between institutions collaborating in research in low- and middle-income countries (LMIC) and high-income countries (HIC) has become an integral part of research capacity building in global health in recent years. In this paper, we offer an example of an academic collaboration between the University of California Los Angeles, Center for Health Policy and Research (UCLA CHPR) and the University of Philippines, Manila, College of Public Health (UPM CPH) that sought to build an equitable partnership between research institutions. The partnership was built on a project to build capacity for research and produce data for policy action for the prevention and care of non-communicable diseases (NCDs) through primary healthcare in the Philippines. The specific objectives of the project were to: (1) locally adapt the Primary Care Assessment Tool for the Philippines and use the adapted tool to measure facility-level primary care delivery, (2) conduct focus group discussions (FGDs) to gather qualitative observations regarding primary care readiness and capacity, and (3) conduct a comprehensive population-based health survey among adults on NCDs and prior healthcare experience. We describe here the progression of the partnership between these institutions to carry out the project and the elements that helped build a stronger connection between the institutions, such as mutual goal setting, cultural bridging, collaborative teams, and capacity building. This example, which can be used as a model depicting new directionality and opportunities for LMIC-HIC academic partnerships, was written based on the review of shared project documents, including study protocols, and written and oral communications with the project team members, including the primary investigators. The innovation of this partnership includes: LMIC-initiated project need identification, LMIC-based funding allocation, a capacity-building role of the HIC institution, and the expansion of scope through jointly offered courses on global health.

The effect of primary health care on AIDS incidence and mortality: a cohort study of 3.4 million Brazilians

Background

Primary Health Care (PHC) is essential for the health and wellbeing of people living with HIV/AIDS. This study evaluated the effects of one of the largest community-based PHC programs in the world, the Brazilian Family Health Strategy (FHS), on AIDS incidence and mortality.

Methods

A retrospective cohort study carried out in Brazil, from January 1 2007 to December 31 2015. We conducted a quasi-experimental effect evaluation using a cohort of 3,435,068 ≥13 years low-income individuals who were members of the 100 Million Brazilians Cohort, linked to AIDS diagnoses and deaths registries. We evaluated the effect of FHS on AIDS incidence and mortality and comparing outcomes between residents of municipalities with no FHS coverage with those in municipalities with full FHS coverage. We used multivariable Poisson regressions adjusted for all relevant municipal and individual-level demographic, socioeconomic, and contextual variables, and weighted with inverse probability of treatment weighting (IPTW). We also estimated FHS effect by sex and age, and performed a wide range of sensitivity and triangulation analyses.

Findings

FHS coverage was associated with lower AIDS incidence (rate ratio [RR]:0.76, 95%CI:0.68-0.84) and mortality (RR:0.68,95%CI:0.56-0.82). FHS effect was similar between men and women, but was larger in people aged ≥35 years old both for incidence (RR 0.62, 95%CI:0.53-0.72) and mortality (RR 0.56, 95%CI:0.43-0.72).

Conclusions

AIDS should be an avoidable outcome for most people living with HIV today, and our study shows that FHS coverage could significantly reduce AIDS incidence and mortality among low-income populations in Brazil. Universal access to comprehensive healthcare through community-based PHC programs should be promoted to achieve the Sustainable Development Goals of ending AIDS by 2030.

The Diffusion of Punitive Firearm Preemption Laws Across U.S. States

INTRODUCTION

Firearm violence is a public health crisis. Most states prohibit local firearm laws, but some states have laws that allow for lawsuits and other penalties against local governments and lawmakers who pass firearm laws deemed preempted. These punitive firearm preemptive laws may reduce firearm policy innovation, discussion, and adoption beyond preemption alone. Yet, it is unknown how these laws spread from state to state.

METHODS

In 2022, using an event history analysis framework with state dyads, logistic regression models estimate the factors associated with adoption and diffusion of firearm punitive preemption laws, including state-level demographic, economic, legal, political, population, and state-neighbor factors.

RESULTS

As of 2021, 15 states had punitive firearm preemption laws. Higher numbers of background checks (AOR=1.50; 95% CI=1.15, 2.04), more conservative government ideology (AOR=7.79; 95% CI=2.05, 35.02), lower per capita income (AOR=0.16; 95% CI=0.05, 0.44), a higher number of permissive state firearm laws (AOR=2.75; 95% CI=1.57, 5.30), and neighboring state passage of the law (AOR=3.97; 95% CI=1.52, 11.51) were associated with law adoption.

CONCLUSIONS

Both internal and external state factors predict the adoption of punitive firearm preemption. This study may provide insight into which states are susceptible to adoption in the future. Advocates, especially in neighboring states without such laws, may want to focus their firearm safety policy efforts on opposing the passage of punitive firearm preemption.

Extracurricular Activities, Child and Caregiver Mental Health, and Parental Aggravation-A National Cross-Sectional Study

OBJECTIVE

Expanding access to extracurricular activities (EA) may help address the growing mental health needs of children and caregivers. Evidence supports that EA may benefit child mental health, but few studies explore whether this association is influenced by child and EA factors. Further, the impact of EA on caregivers remains unknown.

METHODS

We conducted a secondary analysis of the 2019 National Survey of Children's Health (NSCH), a nationally representative sample of children and their caregivers. We used responses from caregivers of children aged 6 to 17. Weighted logistic regressions tested associations between EA and 1) child anxiety and/or depression diagnosis, 2) caregiver mental health, and 3) parental aggravation, controlling for child, family, and neighborhood-level covariates. Interaction terms tested whether associations were moderated by child age, sex, and presence of physical, developmental, or behavioral condition. Subanalyses explored whether results varied by EA number and type.

RESULTS

Weighted sample included 21,259 children. There were disparities in which children were engaged in EA. EA participation was associated with lower odds of a 1) child being diagnosed with anxiety and/or depression; 2) caregiver reporting "fair/poor" mental health, and 3) caregiver reporting "usually/always" experiencing parental aggravation. Child age, sex, EA number and type, but not health condition, influenced the relationship between EA and child anxiety and/or depression diagnosis.

CONCLUSIONS

Access to EA is associated with child mental health and family functioning. Further studies should assess causality and specific mechanisms of action.

The effects of social determinants of health on acquired immune deficiency syndrome in a low-income population of Brazil: a retrospective cohort study of 28.3 million individuals

Background

Social determinants of health (SDH) include factors such as income, education, and race, that could significantly affect the human immunodeficiency virus and acquired immunodeficiency syndrome (HIV/AIDS). Studies on the effects of SDH on HIV/AIDS are limited, and do not yet provide a systematic understanding of how the various SDH act on important indicators of HIV/AIDS progression. We aimed to evaluate the effects of SDH on AIDS morbidity and mortality.

Methods

A retrospective cohort of 28.3 million individuals was evaluated over a 9-year period (from 2007 to 2015). Multivariable Poisson regression, with a hierarchical approach, was used to estimate the effects of SDH-at the individual and familial level-on AIDS incidence, mortality, and case-fatality rates.

Findings

A total of 28,318,532 individuals, representing the low-income Brazilian population, were assessed, who had a mean age of 36.18 (SD: 16.96) years, 52.69% (14,920,049) were female, 57.52% (15,360,569) were pardos, 34.13% (9,113,222) were white/Asian, 7.77% (2,075,977) were black, and 0.58% (154,146) were indigenous. Specific socioeconomic, household, and geographic factors were significantly associated with AIDS-related outcomes. Less wealth was strongly associated with a higher AIDS incidence (rate ratios-RR: 1.55; 95% confidence interval-CI: 1.43-1.68) and mortality (RR: 1.99; 95% CI: 1.70-2.34). Lower educational attainment was also greatly associated with higher AIDS incidence (RR: 1.46; 95% CI: 1.26-1.68), mortality (RR: 2.76; 95% CI: 1.99-3.82) and case-fatality rates (RR: 2.30; 95% CI: 1.31-4.01). Being black was associated with a higher AIDS incidence (RR: 1.53; 95% CI: 1.45-1.61), mortality (RR: 1.69; 95% CI: 1.57-1.83) and case-fatality rates (RR: 1.16; 95% CI: 1.03-1.32). Overall, also considering the other SDH, individuals experiencing greater levels of socioeconomic deprivation were, by far, more likely to acquire AIDS, and to die from it.

Interpretation

In the population studied, SDH related to poverty and social vulnerability are strongly associated with a higher burden of HIV/AIDS, most notably less wealth, illiteracy, and being black. In the absence of relevant social protection policies, the current worldwide increase in poverty and inequalities-due to the consequences of the COVID-19 pandemic, and the effects of war in the Ukraine-could reverse progress made in the fight against HIV/AIDS in low- and middle-income countries (LMIC).

Recreational cannabis legislation and binge drinking in U.S. adolescents and adults

BACKGROUND

Recreational cannabis laws (RCLs) may have spillover effects on binge drinking. Our aims were to investigate binge drinking time trends and the association between RCLs and changes in binge drinking in the United States (U.S.).

METHODS

We used restricted National Survey on Drug Use and Health data (2008-2019). We examined trends in the prevalence of past-month binge drinking by age groups (12-20, 21-30, 31-40, 41-50, 51+). Then, we compared model-based prevalences of past-month binge drinking before and after RCL by age group, using multi-level logistic regression with state random intercepts, an RCL by age group interaction term, and controlling for state alcohol policies.

RESULTS

Binge drinking declined overall from 2008 to 2019 among people aged 12-20 (17.54% to 11.08%), and those aged 21-30 (43.66% to 40.22%). However, binge drinking increased among people aged 31+ (ages 31-40: 28.11% to 33.34%, ages 41-50: 25.48% to 28.32%, ages 51+: 13.28% to 16.75%). When investigating model-based prevalences after versus before RCL, binge drinking decreased among people aged 12-20 (prevalence difference=-4.8%; adjusted odds ratio (aOR)=0.77, [95% confidence interval (CI) 0.70-0.85]), and increased among participants aged 31-40 (+1.7%; 1.09[1.01-1.26]), 41-50 (+2.5; 1.15[1.05-1.26]) and 51+ (+1.8%; 1.17[1.06-1.30]). No RCL-related changes were noted in respondents ages 21-30.

CONCLUSIONS

Implementation of RCLs was associated with increased past-month binge drinking in adults aged 31+ and decreased past-month binge drinking in those aged < 21. As the cannabis legislative landscape continues to change in the U.S., efforts to minimize harms related to binge drinking are critical.

The effects of cash transfer programmes on HIV/AIDS prevention and care outcomes: a systematic review and meta-analysis of intervention studies

BACKGROUND

Poverty and social inequality are risk factors for poor health outcomes in patients with HIV/AIDS. In addition to eligibility, cash transfer programmes can be divided into two categories: those with specific requirements (conditional cash transfers [CCTs]) and those without specific requirements (unconditional cash transfers). Common CCT requirements include health care (eg, undergoing an HIV test) and education (eg, children attending school). Trials assessing the effect of cash transfer programmes on HIV/AIDS outcomes have yielded divergent findings. This review aimed to summarise evidence to evaluate the effects of cash transfer programmes on HIV/AIDS prevention and care outcomes.

METHODS

For this systematic review and meta-analysis, we searched PubMed, EMBASE, Cochrane Library, LILACS, WHO IRIS, PAHO-IRIS, BDENF, Secretaria Estadual de Saúde SP, Localizador de Informação em Saúde, Coleciona SUS, BINACIS, IBECS, CUMED, SciELO, and Web of Science up to Nov 28, 2022. We included randomised controlled trials (RCTs) that evaluated the effects of cash transfer programmes on HIV incidence, HIV testing, retention in HIV care, and antiretroviral therapy adherence, and conducted risk of bias and quality of evidence assessments using the Cochrane Risk of Bias tool and the Grading of Recommendations, Assessment, Development, and Evaluations approach. A random-effects meta-analysis model was used to combine studies and calculate risk ratios (RRs). Subgroup analyses were performed using conditionality types (ie, school attendance or health care). The protocol was registered with PROSPERO, CRD42021274452.

FINDINGS

16 RCTs, which included 5241 individuals, fulfilled the inclusion criteria. Of these, 13 studies included conditionalities for receiving cash transfer programmes. The results showed that receiving a cash transfer was associated with lowered HIV incidence among individuals who had to meet health-care conditionalities (RR 0·74, 95% CI 0·56-0·98) and with increased retention in HIV care for pregnant women (1·14, 95% CI 1·03-1·27). No significant effect was observed for HIV testing (RR 0·45, 95% CI 0·18-1·12) or antiretroviral therapy adherence (1·13, 0·73-1·75). Lower risk of bias was observed for HIV incidence and having an HIV test. The strength of available evidence can be classified as moderate.

INTERPRETATION

Cash transfer programmes have a positive effect on mitigating HIV incidence for individuals who have to meet health-care conditionalities and on increasing retention in HIV care for pregnant women. These results show the potential of cash transfer programmes for HIV prevention and care, especially among people in extreme poverty, and highlight that cash transfer programmes must be considered when developing policies for HIV/AIDS control, as indicated by the UNAIDS 95-95-95 target of the HIV care continuum.

Distinct domains of childhood disadvantage and cognitive performance among older Brazilians: Evidence from ELSI-Brazil

Objective

To investigate the relationship between of distinct domains of childhood disadvantage and cognitive performance among older adults within the context of a middle-income country.

Methods

This study used baseline data (2015/2016) from the Brazilian Longitudinal Study of Aging (ELSI), a nationally representative cohort of 9412 adults aged 50 and over. Nine childhood exposure variables were grouped into three domains (family SES, childhood health, and cultural capital), for which scores were created. Survey-weighted Ordinary Least Squares (OLS) regressions estimated the association childhood disadvantage with cognitive performance as measured by immediate memory, late memory and semantic verbal fluency. Mediation analysis assessed whether adulthood socioeconomic status (SES) mediated this relationship of interest.

Results

Important disparities in cognitive performance were observed, particularly in terms of age, education, income, occupational status. Before controlling for adulthood SES in the multivariable analysis, all domains of childhood disadvantage were found to be associated with lower cognitive performance across all three measures. After inclusion of adulthood SES variables, the observed associations only remained for semantic verbal fluency. Formal mediation analysis indicated that adulthood SES mediates 47.9% (95% CI: 34.3%-78.6%) of the association between later-life verbal fluency and poor childhood health, and 49.9% (95% CI: 43.6%-57.8%) of the association between later-life verbal fluency and low childhood cultural capital.

Conclusions

We found that childhood disadvantage is associated with low performance in memory tests and semantic verbal fluency tests among older Brazilians. Adulthood SES fully mediated the association between all domains of childhood disadvantage and memory performance and only partially mediated its association with verbal fluency. Our findings support policy efforts to enhance early childhood development and improve adulthood SES, and guide additional research to better the mechanisms driving these relationships.

Effective primary care attenuates the association between frailty and hospital admission in old age: the ELSI-Brazil

BACKGROUND

Frailty is a multidimensional syndrome leading to a higher hospitalization. However, few studies explicitly analyze whether measures of effective primary care modify the relationship between frailty and hospital admission.

METHODS

This cross-sectional study included data from the second wave of the Brazilian Longitudinal Study of Aging (ELSI-Brazil), a representative community-based study with older adults aged 50 years and over, conducted in 2019-2021. Self-reported hospital admission in the past 12 months was the outcome. Frailty included the 5 phenotypic criteria: weight loss, exhaustion, low physical activity, weakness, and slowness. The effective primary care index included 12 attributes indicators, continuously. Statistical analyzes comprised logistic regression.

RESULTS

Among the 7,436 study participants, frailty (odds ratio [OR] 2.17; 95% confidence intervals [95% CI] 1.31-3.62) and effective primary care index (OR 1.10; 95% CI 1.03-1.16) were positively associated with higher hospitalization. Interaction revealed that while effective primary care was positively associated with hospitalization, this association was different among frail older adults (OR 0.80; 95% CI 0.65-0.99). After stratification by frailty status, positive association with hospitalization remained only among prefrail and nonfrail individuals. The predicted probability of hospitalization tended to decrease along with higher primary care index values among frail older adults and became similar to prefrail/nonfrail at the highest end of the scale.

CONCLUSIONS

Effective primary care decreases the likelihood of hospital admission among frail older adults. Interventions for delaying frailty should be initiated in primary care along with policies to strengthen primary care's organizational and provider/team-level attributes.

Do alcohol policies affect everyone equally? An assessment of the effects of state policies on education-related patterns of alcohol use, 2011-2019

BACKGROUND

Public policies are a powerful tool to change behaviors that may harm population health, but little is known about how state alcohol policies affect different population groups. This study assesses the effects of a comprehensive measure of the state alcohol regulatory environment (the State Alcohol Policy Score or SAPS) on heavy drinking-a risk factor for premature death-on different population groups, defined by levels of educational attainment, then by race/ethnicity, and sex.

METHODS

We pool each state's Behavioral Risk Factor Surveillance Survey (BRFSS) 2011-2019 and use robust Poisson regression analyses that control for individual-level factors, state-level factors (1 year lagged SAPS score for each state, state fixed effects), and year fixed effects to assess the relationship between SAPS and heavy drinking behaviors by education group. Interaction terms test whether education moderates the relationship by race/ethnicity and gender.

RESULTS

SAPS scores increased 2010-2018, but substantial gaps persist between states. A 10 % increase in a state's alcohol policy score is associated with a 2 % lower prevalence in current drinking (APR=0.97, 95 % CI=0.97-0.97, p < 0.0011) although not for those with a high school education or less. A 10 % increase in the SAPS was associated with a 3 % lower prevalence of heavy drinking; interaction terms in models reveal that a 10 % increase in the SAPS was associated with a lower prevalence of heavy drinking among those with less than a college education.

CONCLUSION

Narrowing gaps in alcohol policies between states may reduce heavy drinking among those with lower educational attainment.

Effect of a conditional cash transfer programme on AIDS incidence, hospitalisations, and mortality in Brazil: a longitudinal ecological study

BACKGROUND

One of the biggest challenges of the response to the AIDS epidemic is to reach the poorest people. In 2004, Brazil implemented one of the world's largest conditional cash transfer programmes, the Bolsa Família Programme (BFP). We aimed to evaluate the effect of BFP coverage on AIDS incidence, hospitalisations, and mortality in Brazil.

METHODS

In this longitudinal ecological study, we developed a conceptual framework linking key mechanisms of BFP effects on AIDS indicators and used ecological panel data from 5507 Brazilian municipalities over the period of 2004-18. We used government sources to calculate municipal-level AIDS incidence, hospitalisation, and mortality rates, and used multivariable regressions analyses of panel data with fixed-effects negative binomial models to estimate the effect of BFP coverage, which was classified as low (0-29%), intermediate (30-69%), and high (≥70%), on AIDS indicators, while adjusting for all relevant demographic, socioeconomic, and health-care covariates at the municipal level.

FINDINGS

Between 2004 and 2018, in the municipalities under study, 601 977 new cases of AIDS were notified, of which 376 772 (62·6%) were in males older than 14 years, 212 465 (35·3%) were in females older than 14 years, and 12 740 (2·1%) were in children aged 14 years or younger. 533 624 HIV/AIDS-related hospitalisations, and 176 868 AIDS-related deaths had been notified. High BFP coverage was associated with reductions in incidence rate ratios of 5·1% (95% CI 0·9-9·1) for AIDS incidence, 14·3% (7·7-20·5) for HIV/AIDS hospitalisations, and 12·0% (5·2-18·4) for AIDS mortality. The effect of the BFP on AIDS indicators was more pronounced in municipalities with higher AIDS endemicity levels, with reductions in incidence rate ratios of 12·7% (95% CI 5·4-19·4) for AIDS incidence, 21·1% (10·7-30·2) for HIV/AIDS hospitalisations, and 14·7% (3·2-24·9) for AIDS-related mortality, and reductions in AIDS incidence of 14·6% (5·9-22·5) in females older than 14 years, 9·7% (1·4-17·3) in males older than 14 years, and 24·5% (0·5-42·7) in children aged 14 years or younger.

INTERPRETATION

The effect of BFP coverage on AIDS indicators in Brazil could be explained by the reduction of households' poverty and by BFP health-related conditionalities. The protection of the most vulnerable populations through conditional cash transfers could contribute to the reduction of AIDS burden in low-income and middle-income countries.

Expansion of primary healthcare and emergency hospital admissions among the urban poor in Rio de Janeiro Brazil: A cohort analysis

Background

Robust evidence on the relationship between primary care and emergency admissions is lacking in low- and middle-income countries. This study evaluates how the phased roll out of the family health strategy (FHS) to the urban poor in Rio de Janeiro Brazil affected emergency hospital admissions and readmissions from ambulatory-care sensitives conditions (ACSCs).

Methods

A cohort of 1.2 million adults in Rio de Janeiro city were followed for five years (Jan 2012 to Dec 2016). The association between FHS use and the likelihood of emergency hospital admissions and 30-day readmissions were evaluated using multi-level Poisson regression models with inverse probability treatment weighting and regression adjustment (IPTW-RA) for socioeconomic and household characteristics. Inequalities in associations were examined across groups of causes and by key socioeconomic groups.

Results

Records from 2,551,934 primary care consultations and 15,627 admissions were analysed. In IPTW-RA analyses, each additional FHS consultation was associated with a 3% lower rate of ACSC admission (RR: 0.97; 95%CI: 0.95, 0.98), a 63% lower rate of 30-day readmissions from any non-birth cause (RR: 0.37; 95%CI: 0.30, 0.46), and an 57% lower rate of 30-day readmissions from ACSCs (RR: 0.43; 95%CI: 0.33, 0.55). Individuals who were older, had the lowest educational attainment, were unemployed, and had higher incomes had larger reductions in ACSC admissions associated with FHS use.

Interpretation

Investment in primary care is important for reducing emergency hospital admissions and their associated costs in LMICs.

Healthcare utilization among older Brazilians during the COVID-19 pandemic: The Brazilian Longitudinal Study of Ageing-COVID-19 initiative

BACKGROUND

As the COVID-19 pandemic progresses, understanding its sustained impact on healthcare access and utilization represents a vital task for decision-makers and health systems. This study investigates how three aspects of health care utilization (i.e., consultations for COVID-19 related symptoms, cancelation of previously scheduled care and hospitalisation in the past 30 days) relate to individual and municipal factors in a nationally-representative sample of Brazilians aged 50 and over.

METHODS

Data were obtained for 6584 participants from the second wave of the Brazilian Longitudinal Study of Ageing (ELSI-Brazil in Portuguese) who were administered supplemental telephone interviews between September and October 2020. Descriptive statistics, bivariate analysis and multivariate analysis using survey-weighted Poisson regression were applied to evaluate all three outcomes of interest (consultation, care cancelation, and hospitalisation). Predicted probabilities were also calculated to understand the overall effect of relevant covariates.

RESULTS

Women were 76% less likely to seek care for COVID-19 symptoms (Odds Ratio [OR] = 0.24, 95% Confidence Interval [CI] = 0.10, 0.53) and 82% more likely to have healthcare cancelled due to the pandemic (OR = 1.82, 95% CI = 1.43, 2.33) than men. Those who live in municipalities with low coverage (<40%) of community-based primary care (the Family Health Strategy) were more likely (OR = 1.80, 95% CI = 1.00, 3.22) to be hospitalised for any reason in the past 30 days and more likely to experience healthcare cancelation (OR = 1.43, 95% CI = 1.01, 2.02). Living in the Southeast and Midwest regions was associated with 62% and 78%, respectively, lower odds of previously scheduled care being cancelled due to the pandemic, in comparison to the North region (OR = 0.38, 95% CI = 0.21, 0.67, and OR = 0.22, 95% CI = 0.14, 0.36). Living in the Southeast region was associated with over 7.61 higher odds of having sought care for COVID-19-related symptoms, relative to those living in the North (OR = 7.61, 95% CI = 2.16, 26.85).

CONCLUSION

Results highlight the uneven impact of the COVID-19 pandemic on health care utilization between males and females, and across Brazilian municipalities and regions.

Primary care experiences among Brazilian adults: Cross-sectional evidence from the 2019 National Health Survey

Objectives

The Brazilian Family Health Strategy (FHS) is strongly associated with better health system performance, but there are no nationally-representative data examining individual-level primary care experiences in the country. Here, we examine reports of primary care experiences among adults with different forms of healthcare coverage (FHS, “traditional” public health posts, and private health plans).

Methods

Data are from the 2019 National Health Survey that included a shortened version of the Primary Care Assessment Tool (PCAT). PCAT questions were administered to a subsample of randomly-selected adults who had a doctor visit within the past 6 months and sought care in a primary care setting (9677 respondents). We used linear regression to examine the association between type of healthcare coverage and PCAT scores adjusted for sex, age, socioeconomic status, health status, geographic region and state of residence.

Results

Primary care experiences in the sample of Brazilians who had a doctor visit 6 months prior to the survey averaged a modest PCAT score of 57 out of 100. Regression models show that users of the FHS had superior primary care experiences, but with large variations across Brazilian regions and states. Individuals selected to respond to the PCAT questions were more likely to be female, older, and poorer, and to be in worse health than the general population.

Conclusions

Brazil’s FHS is associated with modest, but higher-reported primary care experiences than both traditional public health posts and those who have a private health plan. Future iterations of the PCAT module could enhance generalizability by including individuals who had a doctor visit in the past 12 (instead of 6) months.

Education-related health inequities in noncommunicable diseases: an analysis of the Brazilian National Health Survey, 2013 and 2019

This study assesses changes in the prevalence and distribution of noncommunicable diseases (NCDs) and related risk factors among Brazilian adults from the 2013 and 2019 Brazilian National Health Surveys (PNS). It is based on the hypothesis that deteriorating socioeconomic conditions over this period would lead to increased NCDs among the least advantaged populations. We estimated adjusted prevalence ratios by education category and three inequality measures - the slope index of inequality (SII), the relative index of inequality (RII), and population attributable fraction (PAF) - for obesity, hypertension, arthritis, asthma, cancer, depression, diabetes, heart disease, having any chronic condition, and multimorbidity by survey year. We also estimated the 27 Brazilian Federative Units RII and prevalence rates for diabetes and multimorbidity per year and plotted the RII against prevalence by year. Results showed that all NCDs increased over the period observed, ranging from an 8% increase in the adjusted prevalence of arthritis to a 24% increase in the adjusted prevalence of obesity. Measures of inequality showed that most conditions exhibited significant educational inequities in both 2013 and 2019. However, on average, education-based inequities did not significantly change between the two periods. Considering the deterioration of the socioeconomic conditions of most Brazilians, the erosion of social protections, and the continuing economic, political, and health crises occurring in the nation, we observed an urgent need for discussion about the best way to adopt equity-promoting health policies and programs and action to reduce socioeconomic and geographic inequalities in NCDs throughout the country.

Evaluating the impact of social determinants, conditional cash transfers and primary health care on HIV/AIDS: Study protocol of a retrospective and forecasting approach based on the data integration with a cohort of 100 million Brazilians

Background

Despite the great progress made over the last decades, stronger structural interventions are needed to end the HIV/AIDS pandemic in Low and Middle-Income Countries (LMIC). Brazil is one of the largest and data-richest LMIC, with rapidly changing socioeconomic characteristics and an important HIV/AIDS burden. Over the last two decades Brazil has also implemented the world’s largest Conditional Cash Transfer programs, the Bolsa Familia Program (BFP), and one of the most consolidated Primary Health Care (PHC) interventions, the Family Health Strategy (FHS).

Objective

We will evaluate the effects of socioeconomic determinants, BFP exposure and FHS coverage on HIV/AIDS incidence, treatment adherence, hospitalizations, case fatality, and mortality using unprecedently large aggregate and individual-level longitudinal data. Moreover, we will integrate the retrospective datasets and estimated parameters with comprehensive forecasting models to project HIV/AIDS incidence, prevalence and mortality scenarios up to 2030 according to future socioeconomic conditions and alternative policy implementations.

Methods and analysis

We will combine individual-level data from all national HIV/AIDS registries with large-scale databases, including the “100 Million Brazilian Cohort”, over a 19-year period (2000–2018). Several approaches will be used for the retrospective quasi-experimental impact evaluations, such as Regression Discontinuity Design (RDD), Random Administrative Delays (RAD) and Propensity Score Matching (PSM), combined with multivariable Poisson regressions for cohort analyses. Moreover, we will explore in depth lagged and long-term effects of changes in living conditions and in exposures to BFP and FHS. We will also investigate the effects of the interventions in a wide range of subpopulations. Finally, we will integrate such retrospective analyses with microsimulation, compartmental and agent-based models to forecast future HIV/AIDS scenarios.

Conclusion

The unprecedented datasets, analyzed through state-of-the-art quasi-experimental methods and innovative mathematical models will provide essential evidences to the understanding and control of HIV/AIDS epidemic in LMICs such as Brazil.

Reductions in under-5 mortality and public health improvements of the China Healthy Cities (Counties) initiative: a nationwide quasi-experimental study

Introduction

The China Healthy Cities (Counties) public health initiative has been at the forefront of China’s efforts to counteract the growing challenges in the urban environment since the 1990s. It primarily focuses on improving the urban living environment. However, the nationwide health impacts of the initiative remain unexplored.

Methods

We constructed nationwide county-level and city-level panel data from 1996 to 2012 using data on under-5 mortality rates (U5MR), the list of China healthy cities and counties and socioeconomic factors. We used a two-step staggered difference-in-differences approach that exploits variations in the timing of achieving the title of China Healthy City/County. Subgroup analyses by region were performed.

Results

We included 707 cities in the China Healthy Cities study, and 1631 counties in the China Healthy Counties study. Our results indicate substantial and significant reductions in U5MR associated with the public health initiative in China. The association varies across regions with different socioeconomic statuses. China Healthy Cities were significantly associated with a reduction of 0.7/1000 (95% CI −1.2 to −0.2) in under-5 mortality 5 years after cities gained the title and a decrease of 1.4/1000 (95% CI −2.2 to −0.6) 10 years afterward. Cities from western China saw the largest statistically significant gains with 3.2/1000 and 7.2/1000 reductions in child mortality after 5 and 10 years, respectively. China Healthy Counties were also associated with significant reductions in under-5 mortality 8 years after achieving the title; it was associated with 2.6/1000 reductions in under-5 mortality nationwide and 3.8/1000 reductions in eastern China. Our results are robust to heterogeneous treatment effects across cities/counties over time and various model specifications.

Conclusion

Our results suggest significant reductions in under-5 mortality associated with this public health intervention focusing on living environment conditions. Future research could explore differential effects across regions and clarify the underlying causal mechanisms.

Dual Use of Public and Private Health Care Services in Brazil

(1) Background: Brazil has a universal public healthcare system, but individuals can still opt to buy private health insurance and/or pay out-of-pocket for healthcare. Past research suggests that Brazilians make combined use of public and private services, possibly causing double costs. This study aims to describe this dual use and assess its relationship with socioeconomic status (SES). (2) Methods: We calculated survey-weighted population estimates and descriptive statistics, and built a survey-weighted logistic regression model to explore the effect of SES on dual use of healthcare, including demographic characteristics and other variables related to healthcare need and use as additional explanatory variables using data from the 2019 Brazilian National Health Survey. (3) Results: An estimated 39,039,016 (n = 46,914; 18.6%) persons sought care in the two weeks before the survey, of which 5,576,216 were dual users (n = 6484; 14.7%). Dual use happened both in the direction of public to private (n = 4628; 67.3%), and of private to public (n = 1855; 32.7%). Higher income had a significant effect on dual use (p < 0.0001), suggesting a dose–response relationship, even after controlling for confounders. Significant effects were also found for region (p < 0.0001) and usual source of care (USC) (p < 0.0001). (4) Conclusion: A large number of Brazilians are seeking care from a source different than their regular system. Higher SES, region, and USC are associated factors, possibly leading to more health inequity. Due to its high prevalence and important implications, more research is warranted to illuminate the main causes of dual use.

Hesitação vacinal contra a COVID-19 em amostra nacional de idosos brasileiros: iniciativa ELSI-COVID, março de 2021

Resumo Objetivo: Determinar a prevalência e fatores associados à intenção de se vacinar contra a COVID-19 entre idosos brasileiros. Métodos: Estudo seccional, baseado em entrevistas telefônicas de participantes do Estudo Longitudinal da Saúde dos Idosos Brasileiros (60 anos ou mais), conduzidas em 70 municípios, em março de 2021. As análises foram realizadas mediante regressão logística multinomial. Resultados: Entre 4.364 participantes (idade média = 70,1 anos), 91,8% pretendiam se vacinar ou já haviam sido vacinados, 2,5% não tinham essa intenção e 5,7% estavam indecisos. Residentes do Norte e Sudeste brasileiros apresentaram maiores propensões para se vacinar, assim como aqueles com duas ou mais doenças crônicas. Os que se informam sobre a COVID-19 com amigos/familiares/mídia social foram mais propensos a estarem indecisos acerca da vacinação (odds ratio = 3,15; IC95% 1,28;7,77). Conclusão: Identificou-se uma das mais altas prevalências da intenção de se vacinar contra a COVID-19 descritas até a presente data.

Acesso, utilização e qualidade dos serviços de saúde após um desastre: resultados do Projeto Saúde Brumadinho

RESUMO Objetivo: Em janeiro de 2019, uma barragem da mina Córrego do Feijão sofreu um rompimento catastrófico que matou 270 pessoas e causou danos extensos. Não se sabe como a exposição a tal desastre pode afetar a utilização dos serviços de saúde. Métodos: Avaliamos os dados do Projeto Saúde Brumadinho, estudo de coorte que incluiu pessoas expostas ao rompimento da barragem e dois grupos de comparação: pessoas não expostas à mineração ou ao desastre e pessoas de uma comunidade mineira, mas não expostas ao desastre. Os desfechos avaliados foram consulta médica ou hospitalização no último ano, fonte habitual de cuidados, pressão arterial e glicemia verificadas e haver recebido vacinas recomendadas, entre adultos de 18 anos ou mais. A regressão de Poisson robusta ponderada foi usada para avaliar as diferenças entre os expostos e os dois grupos de comparação, controlando por fatores de confusão. Resultados: indivíduos expostos tiveram uma razão de prevalência (RP) 15% maior de relatar uma consulta médica do que os não expostos. Para hospitalização e medidas de pressão arterial e glicemia, não houve diferença significativa entre os grupos. O grupo exposto teve RP 24% maior, e a comunidade mineira RP 143% maior de haver recebido imunizações preventivas em relação ao grupo não exposto. Conclusão: Houve diferenças na utilização dos serviços de saúde entre os indivíduos expostos ao rompimento da barragem. O monitoramento contínuo da situação é necessário, pois as consequências de um evento tão traumático podem levar um tempo considerável para se manifestar.

Healthcare access, utilization, and quality after a disaster: results from the Brumadinho Health Project

ABSTRACT Objective: In January 2019 a dam at the Córrego do Feijão mine suffered a catastrophic failure that killed 270 people and caused extensive damage. It is unknown how exposure to such a disaster might affect healthcare utilization. Methods: We assessed survey data from the Brumadinho Health Project, a cohort study that includes people who were exposed to the dam failure and two comparison groups: people unexposed to mining or the disaster and people from a mining community, but not exposed to the disaster. Main outcomes include any doctor visit or hospitalization in the past year, having a usual source of healthcare, having blood pressure and blood sugar checked, and being up to date with vaccinations, for adults 18 years and over. We used survey-weighted robust Poisson regression to assess differences between those exposed and the two comparison groups while controlling for confounders. Results: In multivariable models, the exposed group had a 15% higher chance of having a doctor visit than the unexposed group. For hospitalization and reports of blood pressure and blood sugar assessments, there was no significant difference among any of the groups. The exposed group had a 24% higher chance and the unexposed mining community had a 143% higher chance of being up to date with immunizations, as compared to the unexposed group. Conclusion: There were some differences in healthcare utilization among individuals exposed to the dam failure. Continued monitoring of the situation is warranted, as the full consequences of such a traumatic event may take considerable time to unfold.

Childhood Disadvantage and Later-Life Multimorbidity: Demonstrating Robustness Under Imperfect Identification

This study assesses the relationship between indicators of early childhood disadvantage and later-life multimorbidity within a nationally representative sample of Brazilians aged 50 and over (n = 9,412). Data come from the baseline assessment (2015/2016) of the Brazilian Longitudinal Study of Aging (ELSI). We employed survey-weighted Ordinary Least Squares regression to estimate the effects of individual and combined measures of childhood disadvantage on the total number of chronic conditions in later life. Mediation analysis assessed whether adult socioeconomic status (SES) mediated the relationship between childhood disadvantage and chronic conditions. We found that individual and combined measures of childhood disadvantage were associated with the total number of chronic conditions, even after controlling for potential confounders. Mediation analysis suggested that part of the effect of childhood adversity is mediated by higher SES in adulthood (~10%). A formal strategy of sensitivity analysis showed that omitted variable bias is extremely unlikely. To rule out the observed effect, an unobserved hypothetical confounder would need the explanatory power of the residual variance of both the independent and the dependent variables that is at least 30 times larger than that of BMI or 5 times larger than the explanatory power of age. Results should inform efforts to strengthen interventions targeting early childhood development and to improve other key inputs (such as education) to enhance adult SES and lessen the impact of early life stressors on health in older adulthood.

Which older Brazilians will accept a COVID-19 vaccine? Cross-sectional evidence from the Brazilian Longitudinal Study of Aging (ELSI-Brazil)

OBJECTIVES

Vaccine hesitancy may represent a barrier to effective COVID-19 immunisation campaigns. This study assesses individual, disease-specific and contextual factors associated with COVID-19 vaccine acceptance among a nationally representative sample of older Brazilian adults.

DESIGN

Cross-sectional analysis of data from household interviews and a supplementary telephone survey.

SETTING

Brazil and its five geographic regions.

PARTICIPANTS

Data are derived from 6584 individuals aged 50 years and over who participated in the second wave of the Brazilian Longitudinal Study of Aging.

PRIMARY AND SECONDARY OUTCOME MEASURES

Survey-weighted multinomial logistic regression assesses factors associated with intending, not intending or being uncertain about one's intention to vaccinate against COVID-19.

FINDINGS

Seventy-one per cent of study participants intend to receive a COVID-19 vaccine once available, while 17% (representative of nearly 9 million people) have no intention to vaccinate, and 12% are still undecided. Besides age, demographic and health-related factors related to COVID-19 severity and complications were not associated with intention to vaccinate. Those who most trusted social media or friends and family for COVID-19 information and those who did not trust any information source were 68% and 78% more likely to refuse vaccination, respectively, as compared with those who trusted official information sources. People who inconsistently used face masks when outside were 3.4 times more likely than consistent face mask users to intend to refuse vaccination. Higher municipal COVID-19 fatality rates were negatively associated with vaccine refusal.

CONCLUSIONS

Most national COVID-19 immunisation strategies identify older individuals as among those prioritised for early vaccination, given their increased risk of more severe symptoms and complications of the disease. Because individual, disease-specific, and contextual factors were associated with vaccine acceptance, there is a clear need for multilevel and multichannel information and outreach campaigns to increase COVID-19 vaccine acceptance among vulnerable older populations.

Trust In Governments And Health Workers Low Globally, Influencing Attitudes Toward Health Information, Vaccines

Trust, particularly during emergencies, is essential for effective health care delivery and health policy implementation. We used data from the 2018 Wellcome Global Monitor survey (comprising nationally representative samples from 144 countries) to examine levels and correlates of trust in governments and health workers and attitudes toward vaccines. Only one-quarter of respondents globally expressed a lot of trust in their government (trust was more common among people with less schooling, those living in rural areas, those who were financially comfortable, and those who were older), and fewer than half of respondents globally said that they trust doctors and nurses a lot. People's trust in these institutions was correlated with trust in health or medical advice from them, and with more positive attitudes toward vaccines. Vaccine enthusiasm varied substantially across regions, with safety being the most common concern. Policy makers should understand that the public may have varying levels of trust in different institutions and actors. Although much attention is paid to crafting public health messages, it may be equally important, especially during a pandemic, to identify appropriate, trusted messengers to deliver those messages more effectively to different target populations.

Life-course risk factors are associated with activity of daily living disability in older adults

BACKGROUND

Multiple risk factors accumulate over the life-course and contribute to higher rates of disability at older ages. This study investigates whether three life-course risk factors (low educational attainment, poor health in childhood and multimorbidity) are associated with increased risk of disability [defined as any limitation in basic activities of daily living (BADL)] in older adults and whether this relationship is moderated by the national socioeconomic context, measured by the Human Development Index (HDI).

METHODS

Data include 100 062 adults (aged 50 and over) participating in longitudinal studies of aging conducted in 19 countries. Analyses include multivariable Poisson models with robust standard errors to assess the associations between HDI, life-course risk factors and other individual-level control variables (sex and age) with any BADL disability.

RESULTS

In country-specific analyses, both educational attainment and multimorbidity are independently associated with disability in nearly every country. The interaction between these risk factors further increases the magnitude of this association. In pooled regression analyses, the relationship between life-course risk factors and disability is moderated by a country's HDI. For individuals with all three life-course risk factors, the predicted probability of disability ranged from 36.7% in the lowest HDI country to 21.8% in the highest HDI country.

CONCLUSIONS

Social and health system policies directed toward reducing the development of life-course risk factors are essential to reduce disability in all countries, but are even more urgently needed in those with lower levels of socioeconomic development.

Family Health Strategy, Primary Health Care, and Social Inequalities in Mortality Among Older Adults in Bagé, Southern Brazil

Objectives. To investigate the role of the Family Health Strategy (FHS) in reducing social inequalities in mortality over a 9-year follow-up period.Methods. We carried out a population-based cohort study of individuals aged 60 years and older from the city of Bagé, Brazil. Of 1593 participants at baseline (2008), 1314 (82.5%) were included in this 9-year follow-up (2017). We assessed type of primary health care (PHC) coverage and other variables at baseline. In 2017, we ascertained 579 deaths through mortality registers. Hazard ratios and their 95% confidence intervals modeled time to death estimated by Cox regression. We also tested the effect modification between PHC and wealth.Results. The FHS had a protective effect on mortality among individuals aged 60 to 64 years, a result not found among those not covered by the FHS. Interaction analysis showed that the FHS modified the effect of wealth on mortality. The FHS protected the poorest from all-cause mortality (hazard ratio [HR] = 0.59; 95% confidence interval [CI] = 0.36, 0.96) and avoidable mortality (HR = 0.46; 95% CI = 0.25, 0.85).Conclusions. FHS coverage reduced social inequalities in mortality among older adults. Our findings highlight the need to guarantee universal health coverage in Brazil by expanding and strengthening the FHS to promote health equity.

Maternal height and double-burden of malnutrition households in Mexico: stunted children with overweight or obese mothers

OBJECTIVE

To assess the association between short maternal height and four types of mother-child nutritional status groupings within Mexican households.

DESIGN

We classified mother-child dyads into four groups: stunted child and a non-overweight/non-obese mother (stunting-only), non-stunted child and an overweight/obese mother (overweight-only), stunted child with an overweight/obese mother (double-burden) and households with neither child stunting nor overweight/obese mothers (neither-condition). We assessed the association between maternal height and mother-child nutrition status using multinomial logistic regression, controlling for socio-economic covariates.

SETTING

Nationally representative cross-section of households from the 2012 Mexican National Health and Nutrition Survey.

PARTICIPANTS

Children <5 years of age were matched to their mothers, resulting in a sample of 4706 mother-child dyads.

RESULTS

We found that among children with stunting, 53·3% have an overweight/obese mother. Double-burden was observed in 8·1% of Mexican households. Maternal short stature increased the probability of stunting-only by 3·5% points (p.p.) and double-burden by 9·7 p.p. (P < 0·05). The inverse association was observed for overweight-only and neither-condition households, where the probability of these outcomes decreased by 7·2 and 6 p.p. in households with short-statured mothers (P < 0·05), respectively.

CONCLUSIONS

Women with short stature are more likely to develop overweight and simultaneously have a stunted child than those who are not short-statured. Our findings underline the challenges faced by public health systems, which have to balance the provision of services for both an undernourished and increasingly overweight/obese population.

Prevalence and characteristics of Brazilians aged 50 and over that received a doctor's diagnosis of COVID-19: the ELSI-COVID-19 initiative

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused over half a million deaths worldwide. Brazil has been particularly impacted, registering more than 1.3 million infections and 57,000 deaths by late June 2020. Aggregate numbers of cases are essential in modeling the epidemic and planning responses; however, more detailed analysis of risk factors associated with SARS-CoV-2 infection are needed. Our study provides an initial examination of characteristics associated with receiving a doctor's diagnosis of COVID-19 among a nationally representative sample of Brazilians aged 50 and over. Data are derived from the second wave of the Brazilian Longitudinal Study of Aging (ELSI-Brazil) and a telephone follow-up survey to ELSI-Brazil participants, known as the ELSI-COVID-19 initiative. The telephone survey was conducted between 26 May and 8 June 2020. Results show that about 2.4% (n = 70) of the sample reported being told by a doctor they had COVID-19, however, only about half of these individuals (n = 37) reported receiving a diagnostic confirmation from viral testing (RT-PCR). Demographic factors (aged 50-60 years), socioeconomic factors (lower household income), health-related factors (obesity, three or more chronic conditions), and geography (living in the Northern region of the country) were positively associated with reporting a COVID-19 diagnosis. Despite the descriptive and preliminary nature of these findings, results reported here suggest the need for more targeted approaches to enhance personal protection and provide greater viral testing options, especially for older, sicker and more vulnerable adults in Brazil.

Why do some countries do better or worse in life expectancy relative to income? An analysis of Brazil, Ethiopia, and the United States of America

BACKGROUND

While in general a country's life expectancy increases with national income, some countries "punch above their weight", while some "punch below their weight" - achieving higher or lower life expectancy than would be predicted by their per capita income. Discovering which conditions or policies contribute to this outcome is critical to improving population health globally.

METHODS

We conducted a mixed-method study which included: analysis of life expectancy relative to income for all countries; an expert opinion study; and scoping reviews of literature and data to examine factors that may impact on life expectancy relative to income in three countries: Ethiopia, Brazil, and the United States. Punching above or below weight status was calculated using life expectancy at birth and gross domestic product per capita for 2014-2018. The scoping reviews covered the political context and history, social determinants of health, civil society, and political participation in each country.

RESULTS

Possible drivers identified for Ethiopia's extra 3 years life expectancy included community-based health strategies, improving access to safe water, female education and gender empowerment, and the rise of civil society organisations. Brazil punched above its weight by 2 years. Possible drivers identified included socio-political and economic improvements, reduced inequality, female education, health care coverage, civil society, and political participation. The United States' neoliberal economics and limited social security, market-based healthcare, limited public health regulation, weak social safety net, significant increases in income inequality and lower levels of political participation may have contributed to the country punching 2.9 years below weight.

CONCLUSIONS

The review highlighted potential structural determinants driving differential performance in population health outcomes cross-nationally. These included greater equity, a more inclusive welfare system, high political participation, strong civil society and access to employment, housing, safe water, a clean environment, and education. We recommend research comparing more countries, and also to examine the processes driving within-country inequities.

ELSI-COVID-19 initiative: methodology of the telephone survey on coronavirus in the Brazilian Longitudinal Study of Aging

The COVID-19 pandemic (caused by the SARS-CoV-2) is a public health emergency of international concern that particularly affects older people. Brazil is one of the countries most affected by the pandemic, ranking second with the highest number of confirmed cases and deaths worldwide as of mid-June 2020. The ELSI-COVID-19 initiative is based on telephone interviews with participants of the Brazilian Longitudinal Study of Aging (ELSI-Brazil), conducted on a nationally representative sample of the population aged 50 or older. This initiative aims to provide information on adherence to preventive measures (social distancing, wearing masks, and handwashing/hygiene); reasons for leaving the house, when that was the case; difficulties obtaining medications, medical diagnosis of COVID-19, and receipt of confirmatory results; use of health-care services (recent care-seeking, care-seeking location, care receipt, among other aspects); and mental health (sleep, depression, and loneliness). The first round of telephone interviews was conducted between May 26 and June 8, 2020. The second and third rounds are expected to occur within the coming months. This article presents this initiative methodology and some sociodemographic characteristics of the 6,149 participants in the survey first round, relative the Brazilian population within the same age group.

Health care seeking due to COVID-19 related symptoms and health care cancellations among older Brazilian adults: the ELSI-COVID-19 initiative

The continent of the Americas has the greatest number of people infected and deaths associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in the world. Brazil occupies the 2nd position in numbers of infected cases and deaths, preceded only by the United States. Older adults and those with pre-existing chronic illnesses are more vulnerable to the consequences of the virus. The SARS-CoV-2 epidemic has serious consequences for health services. Therefore, an assessment of the pandemic's effect on the older Brazilian population is urgently needed. The study examines the prevalence of COVID-19 related symptoms, care-seeking, and cancellation of surgery or other scheduled medical care among a nationally representative sample of Brazilians aged 50 and over derived from the Brazilian Longitudinal Study of Aging (ELSI-Brazil) and a telephone follow-up survey (the ELSI-COVID-19 initiative) between late May and early June 2020. About 10.4% of older adults reported any fever, dry cough or difficulty breathing in the 30 days prior to the interview, with the highest prevalence in the North region (50%). Among individuals with symptoms, only 33.6% sought care. Individuals living in the South or Southeast regions were significantly less likely to seek care for COVID-19 related symptoms. Nearly one in six participants had to cancel scheduled surgery or other medical care; this proportion was higher among women, those with more education, and people with multiple chronic conditions. This paper is among the first to investigate the effect of COVID-19 on health care use in Brazil among older adults. Results highlight the need to adapt health care delivery (such as through telemedicine) to ensure the continuity of care as well as the urgent need for wide dissemination of information to guide the population on disease prevention measures and how to obtain healthcare when needed.

Social distancing, use of face masks and hand washing among participants in the Brazilian Longitudinal Study of Aging: the ELSI-COVID-19 initiative

The aim of the study was to examine the prevalence of social distancing, the use of face masks and hand washing when leaving home among Brazilian adults aged 50 or over. Data from 6,149 telephone interviews were used, conducted between May 26 and June 8, 2020 among participants in the Brazilian Longitudinal Study of Aging (ELSI-Brazil). Social distancing was defined by not having left home in the last seven days. Only 32.8% of study participants did not leave home during the period considered, 36.3% left between one and two times, 15.2% between three and five times and 15.7% left every day. The main reasons for leaving home were to buy medicine or food (74.2%), to work (25.1%), to pay bills (24.5%), for health care (10.5%), to exercise (6.2%), and to meet family or friends (8.8%). Among those who left home, 97.3% always wore face masks and 97.3% always performed hand washing. Women left home less often than men. Men left home more often to work and exercise while women left home more often to seek healthcare. Men (odds ratio - OR = 1.84), those with higher education (OR = 1.48 and 1.95 for 5-8 and 9 years, respectively) and urban residents (OR = 1.54) left home more frequently to perform essential activities, regardless of age or other characteristics. Results show low adherence to social distancing, but high prevalence in the reported use of face masks and hand washing.

Education-Related Inequalities in Dental Services Use among Older Adults in 23 Countries

This study aimed to measure the magnitude of education-related inequalities in the use of dental services among older adults (aged 50 y or older) from a sizable multicountry sample of 23 upper-middle- and high-income countries. This study used cross-sectional data from nationally representative surveys of people aged 50 y and over. Countries included in the Health and Retirement Study surveys were the following: Brazil, China, South Korea, Mexico, United States, Austria, Belgium, Croatia, Czech Republic, Denmark, Estonia, France, Germany, Greece, Italy, Israel, Luxembourg, Poland, Portugal, Slovenia, Spain, Sweden, and Switzerland. The dependent variable was the use of dental services, based on the self-report of having had a dental visit within the previous year, except for the United States and South Korea, which used 2-y recall periods. Educational level was used as the measure of socioeconomic position and was standardized across countries. Multivariate logistic regression modeling was used to evaluate the factors associated with the use of dental services, and the magnitude of education inequalities in the use of dental services was assessed using the slope index of inequality (SII) to measure absolute inequalities and the relative index of inequality for relative inequalities. The pooled prevalence of the use of dental services was 31.7% and ranged from 18.7% in China to 81.2% in Sweden. In the overall sample, the absolute difference in the prevalence of use between the lowest and highest educational groups was 20 percentage points. SII was significant for all countries except Portugal. Relative educational inequalities were significant for all countries and ranged from 3.2 in Poland to 1.2 in Sweden. There were significant education-related inequalities in the use of dental care by older adults in all countries. Monitoring these inequalities is critical to the planning and delivery of dental services.

Unavailability of paid sick leave among parents is a barrier for children's utilization of nonemergency health services: Evidence from the National Health Interview Survey

OBJECTIVE

To assess the association between availability of paid sick leave among parents and children's use of several distinct types of nonurgent health services and emergency care.

METHODS

Using pooled 2013 to 2017 data from the National Health Interview Survey (NHIS), we created dyadic units of observation linking adults with their children (n = 21 235). Descriptive statistics, logistic regressions for binary outcomes, and regular and zero-inflated negative binomial regressions for count outcomes assessed the relationship between parental coverage by paid sick leave benefits and 12 dependent variables related to health care utilization. Regression analyses controlled for a set of child, parent, and family covariates.

RESULTS

Overall, 58.3% of individuals in our sample reported having paid sick leave in their current or latest job. There are substantial disparities in availability of paid sick leave in terms of parent sex, race, education, and income. Controlling for covariates, the odds of children with at least one parent with access to paid sick leave having any visit to a medical office in the past 12 months are 27% higher than for children whose parents do not have this benefit. Similar positive associations were observed for general doctor visit (OR = 1.18, 95%CI: 1.05-1.32), mental health professional visit (OR = 1.19, 95%CI: 1.01-1.42), and receipt of flu vaccination (OR = 1.21, 95%CI: 1.11-1.33). There was no statistically significant association with emergency room use, once covariates were controlled.

CONCLUSIONS

Availability of paid sick leave among parents is associated with increased children's utilization of nonemergency health services and primary care.

Presence of Counterfeit Marlboro Gold Packs in Licensed Retail Stores in New York City: Evidence From Test Purchases

BACKGROUND

There are no independent studies measuring the availability of premium brand counterfeit cigarettes in New York City from licensed retailers.

METHODS

We forensically analyzed the cigarette packaging of Marlboro Gold (n = 1021) purchased from licensed tobacco retailers in New York City, using ultraviolet irradiation and light microscopy to determine whether they were counterfeit.

RESULTS

We find that while only 0.5% (n = 5) of our sample exhibits at least one characteristic synonymous with counterfeit packaging, none of our packs can be conclusively classified as counterfeit.

CONCLUSIONS

We do not find any counterfeit Marlboro Gold packs purchased at full price from licensed cigarette retailers throughout New York City. Future research using test purchases should include other venues (eg, street and online) and specifically ask for discounts to ascertain the overall presence of counterfeit cigarettes.

IMPLICATIONS

This is the first study to independently measure the availability of counterfeit cigarette packs purchased at full price from licensed retailers in New York City. We find that none of the Marlboro Gold packs purchased from licensed cigarette retailers are counterfeit.

Meeting the complex challenge of health and social care provision for rapidly-ageing populations: introducing the concept of "avoidable displacement from home"

The increasing numbers of people at very old ages pose specific policy challenges for health and social care and highlight the need to rethink established models of service provision. The main objective of this paper is to introduce the concept of "avoidable displacement from home" (ADH). The study argues that ADH builds on and adds value to existing concepts, offering a holistic, person-centered framework for integrated health and social care provision for older people. It also demonstrates that this framework can be applied across different levels, ranging from macro policymaking to organizational and individual decision-making. The paper pays attention to the Brazilian context but argues that ADH is a universally applicable concept.

Factors Associated with the Use of Meditation, U.S. Adults 2017

Objectives: Relatively little is known about who uses various types of meditation or how health problems and health care barriers might simultaneously impact its use. This article describes the current prevalence of meditation and identifies significant individual and health system-related factors associated with its use. Design: Cross-sectional descriptive analysis of the 2017 National Health Interview Survey analyzed in 2019. Setting/Location: United States. Subjects: The adult, civilian, noninstitutionalized U.S. population. Outcome measures: Self-reported use of any type of meditation in past year (mantra, mindfulness, spiritual, guided imagery, and progressive relaxation) or as part of yoga or t'ai chi practice. Control variables included demographic characteristics, health status, risk behaviors, and health system-related factors (self-reported barriers and facilitators to health care access) hypothesized to be associated with greater meditation use. Results: Over 46 million people (19% of the adult, civilian, noninstitutionalized U.S. population) currently practice some type of meditation. Three main factors predict meditation use: the presence of a health problem (chronic disease, pain, anxiety/depression, and sleeping problems), cost or access barriers to conventional medical care, and individual characteristics (younger age, female sex, and sexual minority status). Conclusions: Meditation is one of the most common forms of complementary and alternative medicine in the United States today. While its health benefits are still emerging, public health practitioners and clinicians should be aware of the increasing use of these therapies to treat common health problems, their relatively low prevalence among some groups that might benefit from them (such as older people, those with less healthy lifestyles, and men), and their higher use among those who face barriers to obtaining conventional care.

Brazil's unified health system: the first 30 years and prospects for the future

In 1988, the Brazilian Constitution defined health as a universal right and a state responsibility. Progress towards universal health coverage in Brazil has been achieved through a unified health system (Sistema Único de Saúde [SUS]), created in 1990. With successes and setbacks in the implementation of health programmes and the organisation of its health system, Brazil has achieved nearly universal access to health-care services for the population. The trajectory of the development and expansion of the SUS offers valuable lessons on how to scale universal health coverage in a highly unequal country with relatively low resources allocated to health-care services by the government compared with that in middle-income and high-income countries. Analysis of the past 30 years since the inception of the SUS shows that innovations extend beyond the development of new models of care and highlights the importance of establishing political, legal, organisational, and management-related structures, with clearly defined roles for both the federal and local governments in the governance, planning, financing, and provision of health-care services. The expansion of the SUS has allowed Brazil to rapidly address the changing health needs of the population, with dramatic upscaling of health service coverage in just three decades. However, despite its successes, analysis of future scenarios suggests the urgent need to address lingering geographical inequalities, insufficient funding, and suboptimal private sector-public sector collaboration. Fiscal policies implemented in 2016 ushered in austerity measures that, alongside the new environmental, educational, and health policies of the Brazilian government, could reverse the hard-earned achievements of the SUS and threaten its sustainability and ability to fulfil its constitutional mandate of providing health care for all.

Short relative leg length is associated with overweight and obesity in Mexican immigrant women

Background

Prior research suggests that undernutrition and enteric infections predispose children to stunted growth. Undernutrition and infections have been associated with limited access to healthy diets, lack of sanitation, and access barriers to healthcare – all associated with human rights. Stunting has also been documented to be a major determinant of subsequent obesity and non-communicable diseases. Short leg length relative to stature during adulthood seems to be a good proxy indicator tracking such barriers, and has been reported to be associated with adverse health effects during adulthood. Our objective was to examine the association between relative leg length (as measured by the leg length index, LLI) and measures of adiposity – based on body mass index (BMI) and waist circumference (WC) – in a population of recent Mexican immigrant women to the New York City Area.

Methods

The analysis was based on a cross-sectional survey of 200 Mexican immigrant women aged 18 to 70 years, whose data were collected between April and November 2008; although for purposes of the current study we restricted the sample to those aged 18 to 59 years. The dependent variables were BMI and WC, both transformed into categorical variables. The main independent variable was LLI, and other correlates were controlled for (i.e. age, education, having had children, characteristics of the community of origin, acculturation, chronic conditions, sedentary behaviors, access to fresh fruits and vegetables). Two probit models were estimated: the first one analyzed the effect of LLI on BMI categories and the second one estimated the effect of LLI on WC.

Results

The probit assessing the effect of LLI on overweight/obesity suggested that having a short LLI increased the probability of overweight/obesity by 21 percentage points. Results from the probit model estimating the effect of LLI on WC indicated that having a short LLI increased the probability of having abdominal adiposity by 39 percentage points. Both results were statistically significant at p < 0.05.

Conclusion

The study found an association between having shorter legs relative to one’s height and increased risk of overweight/obesity and abdominal adiposity. Findings support the epidemiological evidence regarding the association between short leg length, early life socioeconomic conditions (i.e. limited access to basic rights), and increased risk of adverse health effects later in life.

Reform movements in the Federal District Health Care System:conversion of the Primary Health Care assistance model

CONCLUSION

The Unified Health System has undergone constant evolution and expansion since the publication of Brazil's 1988 Federal Constitution. The Federal District has provided contributions to the field of Primary Health Care Policy, especially between 2016 and 2018, by defining the Family Health Strategy as the definitive way of organizing Primary Health Care (PHC) services and by establishing a set of actions aimed at conversion of existing PHC services to this model. This article describes and analyzes the key processes of this change. The method used was analysis of ordinances, resolutions, reports and other documents, as well as assessment of data from official databases. We emphasize the development of a normative structure that includes the teams' implementation, the professionals' work processes, changes in medical specialties and reorganization of the health professionals who already worked in PHC. with an effect of increasing the population's Family Health Strategy coverage (in a population of approximately 3 million inhabitants) from 28% to 69% during a two-year period, the experience demonstrates the feasibility of incremental changes in health policies such as defining priorities, better management of the workforce, training and decentralized planning to increase access to health services.
